Chapter 440 Zhu Di’s Attitude: Brothers Should Settle Accounts Clearly!

on sea level.

One warship after another, riding the wind and waves, approached Jilong Island.

The bow deck of the royal ship.

Zhu Yuanzhang and Zhu Biao took all the royal family members of the Zhu family and looked far away. In the distance, the lush land appeared in their sight.

Sandwiched between two mountains, the sea extends inward.

‘Is this Jilong Island? ’

After two days of sailing, everyone basically experienced some dangers in the sea.

Seeing the bay sandwiched between two mountains, they all secretly breathed a sigh of relief, and a sense of security suddenly rose in their hearts.

Everyone looked curiously at the increasingly larger island as the warship approached.

"Father, look, a boat is coming out!"

Zhu Yunwen suddenly pointed at the two small black spots coming out of the bay and shouted.

He secretly murmured with pride: Look, the imperial court is always on the throne. Not only does the fourth uncle have to go to Jiangsu and Zhejiang to welcome him, but now that they are in the fourth uncle's territory on Jilong Island, the people under the fourth uncle also have to rush to please the imperial court.

Grandpa said that after the separation between the Fourth Uncle and the Ming Dynasty, he wanted to have the same status as the Yan Fan and the Ming Dynasty, but it would never come true.

Grandpa was indeed right.

Thinking about...

Zhu Yunwen raised his head slightly and glanced at Yong Ming and Qi Hua who were standing next to Zhu Yuanzhang and Ma Xiuying, and Cai Lu was chattering in a low voice. He couldn't hear what they were saying.

They brothers and sisters will always be inferior in front of him!

Because his father is the crown prince of Ming Dynasty!

The future emperor!

The father of the Zhu Yongming brothers and sisters was just one of the many sons of the imperial grandfather.

So what if they were pampered by the imperial grandfather and the imperial grandmother!

…

"Fourth brother is here."

While everyone was silently looking at Jilong Island, a princess saw Zhu Di coming from the flagship in a small boat and shouted.

With Zhu Yuanzhang and others watching, Zhu Di boarded the royal ship and quickly came to Zhu Yuanzhang, clasping his fists and saying, "Father, before entering the harbor, the coastal defense artillery on the hills on both sides of the bay will demonstrate shelling for my father. Do you want to see it?"

Zhu Yuanzhang smiled and glared, "I am under your rule and I will follow your arrangements. We only have our eyes and ears, you can make whatever arrangements you want."

Zhu Di smiled and gestured to the boat that sent him down below.

Soon, the entire fleet stopped about twelve or three miles away from the entrance of the bay.

"What is this going to do?"

"Yes, why don't you leave? We still want to see what King Yan's Jilong Island is like. Why did he stop at the door of his house and not let us in?"

"Do you feel that you cannot compare with our fortified cities in the Central Plains?"

…

On another large ship, the officials watched the entire fleet stop and joked.

Zhu Silang is indeed capable.

Over the years, an invincible fleet has been built.

A new army of tens of thousands of people.

But the little money he got was probably all spent on this, right?

Not to mention the city inside Jilong Island.

I'm afraid there aren't any decent buildings, right?

Li Shanchang waved to the shipowner who was standing not far away, and everyone fell silent.

After the ship owner came.

Li Shanchang asked: "What is this going to do?"

The shipowner smiled and bowed slightly, "Mr. South Korea, the warships around us have just signaled that they are about to conduct a coastal defense artillery bombardment demonstration. The ship being towed should be the target ship..."

All officials looked embarrassed for a moment.

"Are you trying to intimidate us?"

"The coastal defense gun is set up on the ridge. How can it hit such a small boat from such a long distance?"

"Want to see it!"

"Yes, I want to see how Yan Fan's shore defense artillery, which was so praised by Jin Yiwei, is doing!"

…

On this ship, Li Shanchang and others were curious, but the other officials were all filled with indignation and their faces were full of anger.

Isn't it just artillery?

Doesn’t the imperial court have it?

Weird and sexy skills!

Lu Ben was sitting in a wheelchair. Neither he nor Hu Weiyong spoke. They looked at each other and looked at the target ship that was getting closer and closer.

On the royal ship.

Zhu Yuanzhang watched the target ship stop three miles away. The naval warship towing the target ship went to Zhu Di's flagship. After receiving the order from the flagship, it sailed towards the bay.

He turned around and asked: "Fourth, from such a long distance, can your shore defense artillery really hit the target ship?"

He made a visual inspection.

The distance between the target ship and the entrance of the bay is at least ten miles.

Ten miles!

If a person travels on foot, it will take about three or four incense sticks!

How can artillery fire such a long distance?

Are firearms so powerful?

He never underestimated the power of firearms.

During the Yuan Dynasty, his army already used firearms.

Over the years, the new army trained by Laosi, with bronze cannons and rifles, has proved the power of firearms.

But even though he was ten miles away, he still didn't believe it.

Jin Yiwei has reported this news.

But he still had doubts.

Zhu Biao and others also looked at Zhu Di.

In fact, at this distance, if you look at it visually, it seems impossible.

Zhu Di said with a smile: "Father, the effective range of this coastal defense gun is eight miles, but because it is installed on the mountain ridges on both sides and the terrain is high, the effective range can reach about eleven miles..."

Just when Zhu Di was explaining to Zhu Yuanzhang and others.

Inside the forts on the mountain ridges on both sides.

Wen Qi and other artillery battalion commanders and a group of naval gunners gathered around the giant 3.3-meter-long cannon, drooling greedily.

"It will be great when our army can deploy this kind of artillery."

"Old Wen, stop dreaming. It weighs one ton. Even if you are really equipped with it, what will your army use to pull this huge cannon? Warhorse?"

"Haha..."

"Yes, yes, yes, Old Wen, stop dreaming. If you ask me, our navy may still have a chance to use this huge cannon. Our navy's warship, the flagship, has a maximum load of 30 tons. As long as the problem of hull strength is solved, this huge cannon may be installed. Except for our navy, your army will never be able to do it!"

...

Just when a group of navy and army officers were arguing, the messenger ran up from the bottom of the mountain panting.

Shouted: "Prince's order, start the artillery drill!"

Navy and army officers evacuated the artillery platform one after another.

When Wen Qi and others passed by Dongxu, they all smiled and patted Dongxu on the shoulder, encouraging him: "Don't be nervous. Even if our huge cannon can't hit the target ship, the momentum is loud enough!"

Dongxu nodded with a smile, and was very grateful for the encouragement of these uncles.

He also didn't know whether the improved coastal defense artillery scale he had made in the past few months based on the artillery scale used by the army was useful.

Because of the differences in caliber, projectile size, weight, and charge.

He couldn't guarantee the accuracy of the coastal defense artillery scale he had just completed.

He just readjusted and corrected the original scale based on the multiple relationship between the caliber, projectile, and charge of the two types of artillery.

He now only has superficial practical experience in ballistics.

The set of scales used by the army was summarized by Uncle Wen after he fired a full 534 projectiles through repeated measurements.

Although he divided the trajectory into horizontal and vertical directions.

And proved that the landing time in the vertical direction has nothing to do with the weight of the projectile.

The falling speed and time seem to be positively correlated.

...

But he is now stuck on the issue of time.

The accuracy of the various timing tools he can find now is too poor.

It is impossible to effectively summarize the specific relationship between speed and time.

He was trying to find a solution...

...

Dongxu was nervous and followed the cleared shooting channel. He squinted his eyes to measure the direction of the target ship on the sea, and then put the ruler close to the gun barrel to measure.

After a while, he said loudly: "Two body positions to the left, raise the muzzle elevation by one ruler scale!"

Look, this is the trouble he is facing now.

He didn't even unify and perfect the unit to adjust the artillery.

...

Outside the turret.

Wen Qi and others watched as Yang Dongxu commanded the soldiers of the coastal defense battalion to use the turntable to adjust the muzzle elevation and left and right.

He nodded slightly.

Wen Qi turned his head and smiled at his navy comrades: "Don't look at Dongxu's young age. The set of rulers he made for our army is very useful..."

A group of navy captains couldn't help but twitch their lips when they heard Wen Qi's boasting.

Their navy is different from the army.

Compared with the accuracy rate.

Their navy pays more attention to the speed of artillery fire when fighting at sea.

The speed of artillery fire increases the density of artillery fire.

The accuracy is not enough, but the density is enough!

Nothing else.

On the sea, not only are the warships moving all the time, but the sea surface is also not calm, and it is violently shaking all the time.

There are too many variables.

The set of scales summarized by Dongxu cannot be used in the navy at all.

The density of artillery fire, and the soldiers who operate the artillery, the kind of inexplicable perception and judgment.

Finally, add a little bit of luck.

...

On the sea in the distance.

As long as the coastal defense artillery was operating for a while, all officials began to sneer.

"Could it be that their coastal defense artillery is broken?"

"If so, the King of Yan will probably feel very uncomfortable."

"It can't show us power!"

...

Imperial ship.

Zhu Biao turned his head and whispered to Zhu Di who was standing beside him, "Old Four, does it take so long for this coastal defense artillery to load and fire? At this time and this distance, if the enemy really attacks your Jilong Island, I'm afraid the enemy has already rushed in?"

Zhu Yuanzhang and others heard the voice and looked at Zhu Di.

Zhu Di smiled and shook his head, pointing to the right ridge, "Dongxu has been tinkering with the shore defense gun scale in the past few months since he came back. It seems that today is the first test firing..."

"The shore defense gun is ten feet long and weighs one ton. It is indeed very heavy and not easy to operate. However, the shore defense gun is different from our infantry guns and naval guns in terms of usage..."

"There are two guns on each of the hills on both sides of Jilong Island. The correct way to use it should be that the four guns are deployed in the drill. During the training, as long as the gunners remember the fixed firing area of ​​the guns assigned to their respective teams, the muzzle elevation range, and the left and right range, during the enemy's attack, they only need to aim at the firing area of ​​daily training..."

In fact, the shore defense gun does not need any scale at all.

It's just that Dongxu wants to try it.

He happily supports it.

Although this kind of research is not very useful for the current shore defense guns.

But it will give a deeper understanding of ballistics.

It should be helpful for Dongxu to study ballistics.

Zhu Biao nodded and looked at Zhu Di out of the corner of his eye.

He was very puzzled.

Yang Dongxu is the favorite student of the fourth brother.

Why not let Yang Dongxu go into politics or the military?

With Yang Dongxu's ability, if he goes into politics or the military, he can definitely become the biggest helper of the fourth brother after training for one or two years.

But the fourth brother let Yang Dongxu do these strange skills.

Don't like Yang Dongxu?

Forget it, this is the matter between the fourth brother and his students, he doesn't need to say anything.

Boom!

The sudden roar interrupted Zhu Biao's thoughts.

Zhu Biao, Zhu Yuanzhang and all the others immediately looked in the direction of the sound.

When the thick smoke floated from the hill on the right, a black bullet about the size of a human head came whistling.

Bang!

The bullet hit the sea surface about twenty steps to the right of the target ship.

In an instant, a huge wave rose into the air.

It reached a height four times that of the target ship before a wave broke out.

The sea surface was even more turbulent.

The target ship shook violently from side to side.

Zhu Yuanzhang and all the people on the southern tour had their eyes widened instantly.

At this moment, everyone finally believed it.

Yan Fan's coastal defense artillery can really fire for ten miles!

At this distance, they can't even see the shadow of the gunner!

In other words, Yan Fan has mastered the weapon that can kill the enemy without even seeing the enemy's shadow?

…

"Good!"

Around the artillery, Wen Qi and others looked at the point where the shells landed, and couldn't help but cheer loudly: "Dongxu, good job!"

Yang Dongxu pursed his lips reservedly.

In fact, he already knew from chatting with the uncles in the coastal defense camp that the coastal defense artillery did not need a ruler.

But the master indulged him and encouraged him to study.

It turns out that the trajectory of both coastal defense artillery and army artillery is the same.

This proof result is very useful.

The master is like this, always willing to encourage them to toss.

Dongxu tried to gather his thoughts, clenched his fists and raised his arms horizontally, and stretched out his thumbs parallel to his eyes.

Evaluating visually, he shouted loudly: "Adjust half a body to the left again!"

"Adjustment completed!"

"Another test shot!"

Bang!

…

Bang!

The eight-inch projectile fell close to the starboard side of the target ship.

Zhu Yuanzhang's eyes trembled, "Is the artillery scale made by our apprentice so effective? The second artillery shot almost hit the target ship?"

Apprentice?

Zhu Di, Ma Xiuying, Chang, Guanyinnu and others all laughed.

Zhu Di smiled and shook his head.

If the emperor doesn't like someone, he may be hypocritical for the sake of interests.

But if he likes someone.

He will not hide it.

Hum!

Zhu Yuanzhang snorted slightly, "I am their master, aren't they our disciples? Dongxu's research also has our share, right?"

"Yes, yes, yes." Zhu Di smiled and shook his head. Anyway, the artillery scale had been handed over to Lan Yu and others. Zhu Di explained: "The artillery scale is indeed very helpful in improving the accuracy of artillery, but it is not as powerful as it was just now..."

Due to the accuracy of the artillery barrel, shells, and charge, even with the help of the scale, the results of each artillery attack are very different.

Just like the barrel.

When making wooden barrel molds, there is always a gap between each mold.

And there will be a gap when pouring the mold.

For an eight-inch barrel, the accuracy difference between each gun is actually very large.

In the production of projectiles, sufficient margins must be left.

However, the master craftsmen in the workshop are already seeking to improve these problems.

Try to make the measuring tools more refined.

For example, the smallest unit of length in all dynasties is the inch.

But this accuracy is too large for making cannons and fire guns.

Before, the craftsmen had divided the inch into three equal parts.

Slightly larger than 1 cm.

This accuracy is used to divide one centimeter into three equal parts.

This accuracy can only be said to be barely enough.

Now, several children of Yuanji who are the best in mathematics are studying with a group of master craftsmen how to make the length unit more accurate.

Many problems were encountered in the experiment.

At the same time, they are also discussing whether to re-establish a set of length units.

Because they encountered trouble in trying to divide an inch.

After dividing an inch into three equal parts, each part is 1.11 cm.

This number is difficult to divide evenly.

I don’t know what the result of the argument between Yuanji’s children and the master craftsmen was.

Boom! Boom! Boom!

Just as Zhu Di was lost in thought, three rounds of test firing were conducted on the hill on the right.

Bang!

When the third round of test firing shells fell, they hit the target ship.

A target ship that was not small.

As everyone watched, the moment the shells hit the bow deck, the stern actually tilted up!

Hiss!

"What a powerful force, this ship is not small!"

Everyone exclaimed.

...

Boom boom boom!

After Dongxu commanded a coastal defense gun to hit the target ship, the other three coastal defense guns that had already been adjusted to the firing area where the target ship was located began to join the bombardment.

Boom! Boom! Boom!

Shells hit the water surface one after another, splashing one wave after another.

The target ship swayed and bumped violently on the sea.

In the firing area where the target ship was located, the sea surface suddenly surged like a river turning upside down.

Crack!

It was hit four times in a row. Even if it was two or three miles away, everyone could clearly hear the violent cracking sound.

Then, the eyes of the observers, who were already holding their breath and looking extremely solemn, suddenly widened.

They saw that the target ship, which was already riddled with holes, suddenly broke into two.

Then, a huge vortex appeared on the sea surface, swallowing up a target ship that was not small in the eyes of the crowd and could go out to sea at a speed visible to the naked eye!

The officials were pale and whispered.

"Is the keel broken?"

"It must be, otherwise it would be impossible to break into two. Is there anyone who can completely destroy such a large ship that can sail in the sea with just a few hits?"

"Five times! Only five times!"

…

There were several people, and after speaking out, all the officials were silent for a moment.

Five hits to sink such a big ship in their eyes?

What about the naval warships currently used by the imperial court in rivers and lakes?

I'm afraid it only takes two or three rounds to send it into the sea, right?

Royal ship.

Silence fell.

Zhu Biao finally came to his senses, looked at Zhu Di, and said with a smile: "Fourth, can you provide your coastal defense artillery manufacturing technology to the imperial court? If the imperial court has it, can it be made by the imperial craftsmen?"

The imperial court needs such artillery!

As the warships were equipped with artillery, their power became more and more powerful.

Originally, the navy could only be regarded as a supplement to the Ming army.

But things are different now.

In the future, the mouth of the Ming Dynasty's waterway and both sides of the Qinhuai River in Jinling should also be equipped with this kind of shore defense artillery.

"Brother, I don't know much about the skills of the imperial cannon-smiths." Zhu Di smiled and was vague.

The imperial court wanted the technology of coastal defense artillery.

You have to exchange something.

From now on, it will not be given to you in vain.

The eldest brother didn't say anything clearly.

But if the imperial court wants to deploy coastal defense artillery, who should it be guarding against?

Looking at the world, in the next fifty years, the only one who can threaten the Ming Dynasty is Yan Fan, right?

It was obviously to guard against him.

Before the navy followed him back to the Ming Dynasty, some people deliberately spread rumors about how his navy threatened Jinling.

It is said that the eldest brother intends to move the capital to Guanzhong, just like in history.

He didn't know.

In this era, the eldest brother moved the capital to Guanzhong, and he really just liked Guanzhong.

I still wanted to be on guard against him.

Of course, these are not important.

As the crown prince of the Ming Dynasty.

It is normal for the eldest brother to consider Ming Dynasty’s homeland security.

Zhu Biao was slightly stunned.

I always felt that Zhu Di was being vague.

Zhu Yuanzhang glanced at Zhu Biao and Zhu Di and said with a smile: "The bombardment is very shocking. Next, take us into the harbor and take a good look at your Jilong Island."

He spoke slightly louder on 'you'.

‘I hope Biao’er can realize soon that the fourth child now is no longer the fourth child who led troops back to the DPRK to help in the war! ’

Zhu Yuanzhang sighed secretly.

What Biao'er said just now was like before, asking for nothing for nothing.

But the whole Ming Dynasty was shouting and killing, and Biao'er's attitude towards Chang Mao after he woke up.

Can the fourth child still give everything to the court for free?

He understood it even then.

Therefore, on the grounds of the outstanding achievements of Army No. 1 Town, he gave a year's tax in Fujian to Lao Si.

Otherwise, if he, as a father, wants to give the fourth child something in the future, he will not be able to give it to him.

The imperial court was originally opposed to his funding Lao Si.

Once the fourth child wants to negotiate terms with the court.

Everyone in the imperial court was definitely more opposed to his free funding of the fourth child.

He gave it to the fourth child.

This time, the fourth child did not refuse and accepted.

Only their father and son understand this. This is between father and son, the father's father's love for his son, and the son's filial piety not to let his father worry!

later.

Biao'er wanted to get something from Lao Si again.

First of all, the fourth child must be willing.

Secondly, we have to settle the accounts with our brothers!

After Zhu Di accepted the order, he quickly issued the order.

Woo woo woo...

The horn sounded.

"Let it go! Let it go! Let it go!"

The outer warship commanders began to issue orders.

Boom boom…

Hundreds of cannons pointed outwards, and aerial cannons fired as the fleet slowly sailed into the bay.

Within the bay.

Other warships of the navy were already waiting on both sides of the coast.

After the fleet entered the bay, they all greeted it with a cannon salute.

"Long live Long live Long live!"

"Long live Long live Long live!"

…

On the coast, the people who greeted the Holy Emperor knelt down and worshiped him.

The captain of the ship was in the middle of the fleet.

Zhu Yuanzhang entered the bay amidst the cannon salute and the shouts of "Long Live the Mountain".

As far as the eye can see, there are dense crowds of people kneeling and worshiping.

Behind the people, rows of red-brick, wooden and tile-roofed houses stand.

On both sides, after the gun salute was completed, naval officers wearing new military uniforms stood on the inner side of the ship and stood at attention to salute.

Zhu Yuanzhang turned his head, his face flushed slightly, he couldn't control his smile, he glared angrily and cursed: "What are you doing with these vain things!"

Ma Xiuying smiled and shook her head with Chang, Guanyinnu and other daughters-in-law.

It was too loud.

They had never seen such a welcome.

So shocking.

Chongba obviously likes the fourth child's arrangement, but he still doesn't want to admit it.

Zhu Di nodded with a smile: "Father, I understand. Next time Father comes, he will not engage in such foolish things. This time Father will bear with it."

‘Let’s just talk about it, why do you take it so seriously! ’

Zhu Yuanzhang's lips twitched.

Suddenly, I couldn't help but feel a little sad.

next time……

He is already so old, can he still visit the fourth child again?

I'm afraid, this is the last time, right?

That's why this brat said this.

The boat arrived at the dock.

Zhu Yuanzhang was the first to disembark.

Followed by Zhu Xi, Lan Yu and others on the flagship.

When it was the turn of the civil and military officials on another giant ship, except for Li Shanchang and a few others, all the civil and military officials were a little lost.

The welcoming ceremony just now was so shocking.

For a moment.

They thought Zhu Silang wanted to take the opportunity to kill them all!

Moreover, Dongfan does not seem to be desolate.

The rows of buildings with red brick roofs seemed more majestic than what Jian'an had seen!

Boo! Boo! Boo...

When the sound of cannons sounded again, the devastated officials came back to their senses.

They all looked forward.

An army formation stood in formation in a broad field in front.

Rows of yellow-orange-orange bronze cannons, with red silk tied to the barrels, roared with bursts of white smoke rising.

Zhu Yuanzhang pointed forward and asked with a smile: "What kind of nonsense is this?"

Zhu Di rolled his eyes helplessly.

This old man obviously likes her very much, but he insists on speaking harshly.

He really wanted to order the withdrawal directly.

Angry old man.

Forget it, this is probably the first and last time the old man comes to Dongfan to see him. Let him do whatever he wants.

He introduced with a smile: "Father, this is the review ceremony, the etiquette of the Yanfan vassal. During the exchanges between countries, when welcoming important envoys or the head of a country, this kind of etiquette will be used in the future, and the scale will be different. This time Welcoming the emperor is of the highest standard, with the navy and army reviewing it at the same time.”

Zhu Yuanzhang nodded, "Then dad will inspect and review."

As he spoke, the corners of his lips could not help but curl toward his ears.

So happy!

Zhu Di accompanied Zhu Yuanzhang in the front, followed closely by Ma Xiuying and Xu Miaoyun, followed by Zhu Biao, Crown Princess Chang and others.

At the end are the civil and military officials.

"stand at attention!"

despair!

When Zhu Yuanzhang passed by, Zhang Wu, the commander of the First Association and the First Standard Association, shouted loudly, and the first standard soldiers immediately raised their heads and stood at attention.

"salute!"

Snapped!

Thousands of soldiers beat their chests and saluted.

Pay attention.

When Lan Yu and Mu Ying passed by, they looked at Zhang Wu and others, nodded and smiled, and whispered: "Not to mention, Zhu Laosi's welcoming ceremony not only showed grandness and solemnity, but also demonstrated the power of Yan Fan. , it would be great if the court could follow suit.”

Mu Ying glanced at the civil servants and smiled bitterly, "Impossible, our civil servants in the court can let our military get such limelight? In the eyes of the civil servants, we are a bunch of vulgar people!"

The look of disappointment in Lan Yu's eyes flashed away.

…

After Zhu Yuanzhang passed by the reviewing team, Jiang Jinzhong and others came up to him, and they all bowed and paid homage.

There was no kneeling.

Just bow down and pay homage.

This scene fell in the eyes of the officials, and whispers sounded.

"snort!"

"Even their masters knelt down to worship His Majesty, but they just bowed!"

"Yan Fan is really rebellious!"

…

Zhu Yuanzhang didn't mind at all.

He had known that under the rule of Lao Si, the kneeling ceremony was cancelled.

Not just officials.

Even the common people are like this.

Zhu Yuanzhang looked at Jiang Jinzhong and Xia Shimin...

Especially Jiang Jinzhong and other officials who followed Zhu Di to Dongfan early to build Dongfan.

These people tell the truth.

Placed within the territory of the Ming Dynasty, they are all average-looking.

It stands to reason that anyone picked out in the imperial court would have better qualifications than this group of people.

But in terms of doing things, it's just the opposite.

This group of people in Dongfan helped Lao Si create this prosperous and astonishing business.

Extremely strong in practical ability.

But those in the court who were more talented and better qualified were doing nothing.

What is it that causes outstanding talents to be inferior to those with average qualifications?

Zhu Yuanzhang came to his senses and patted Jiang Jinzhong on the shoulder, "Jinzhong, you have worked hard to assist our fourth child these years. I hope you can continue to do this in the future. Our fourth child will definitely not treat you badly."

Jiang Jinzhong's voice trembled with excitement, "Your Majesty, Jinzhong will continue to work hard and never forget his original intention!"

This is Your Majesty!

How could His Majesty ever do this to an outsider?

I'm afraid that Jiang Jinzhong is the only one in the world who has this honor.

Zhu Yuanzhang encouraged everyone a few more words, and then he and Zhu Di continued to walk forward. Jiang Jinzhong went to the back to find Lan Yu, Fang Xiaoru and others who were familiar with him.

After walking down the red carpet.

Huh!

Zhu Yuanzhang let out a sigh and finally noticed the smooth pavement under his feet without any gaps.

Others were alarmed by Zhu Yuanzhang's movements and lowered their heads.

Zhu Yuanzhang rubbed his toes and looked at Zhu Di curiously: "Fourth, what kind of stone is this? How did you use it to create such a long, wide, and complete stone slab?"

Finally found it!

Zhu Di smiled secretly and replied: "Father, this is not a stone, this is cement. We, Yan Fan, have just made an adhesive. It is somewhat similar to the rice slurry used in building cities, but it is cheaper than rice slurry. Stones are used in the blast furnace. It is fired at high temperature inside, mixed with sand and gravel, and solidified when exposed to water..."

…

"The cost is very low, and the problem of large-scale mass production has been solved. It can be used to build such permanent roads, and can also be used to build houses and farmland water conservancy. In short, it has a wide range of uses and is durable."

…

Behind the crowd, Baiguan's expression became more solemn again.

Hu Weiyong and Lu Ben looked at each other silently.

Zhu Yunwen bent over, reached out and dug hard.

Lan Yu walked quickly to Zhu Di and couldn't wait to ask: "Your Majesty, this kind of cement can build houses, can it also build fortresses?"

He is now the top military commander of the demonstration area.

The entire grassland north of Yinshan Mountain has become a mess.

He wanted to ensure the stability of the demonstration area.

It must be ensured that the war north of Yinshan Mountain cannot spread to the demonstration area south of Yinshan Mountain.

Cement if strong enough.

Can build forts.

There is no shortage of stones in Yinshan Mountain.

He could build a large fortress at a barrier like the Three Gorges Pass in Yinshan, and then build a series of small fortresses along the Yinshan Mountains.

In this way, the entire demonstration area would be impregnable.

Zhu Yuanzhang and Zhu Di both understood why Lan Yu was so anxious.

Zhu Di also hoped that the demonstration area would be good.

The Mongolian people in the demonstration area had done him a favor.

And it was a political fortune he left to Xiongying.

He nodded with a smile, "Yes, the turrets of the coastal defense artillery are built with cement, which can withstand the recoil of the eight-inch cannon. As long as the fortress is built reasonably, even ordinary infantry artillery will find it difficult to blow it down."

Lan Yu nodded and rubbed his hands with a smile.

However, he did not ask Zhu Laosi directly for it.

Times have changed, and the situation has changed.

Zhu Laosi was shouted and killed like that.

The prince had that attitude.

How could he have the nerve to ask Zhu Laosi directly for it.

Just make sure the cement works well.

After settling down, he asked His Majesty for instructions and listened to His Majesty's opinion.

After the episode ended.

Zhu Di accompanied Zhu Yuanzhang to continue walking forward.

"Such thick smoke! Fourth brother, is there a fire!"

During the march, behind him, Lao Jiujiu pointed to the deep southwest of Jilong Island and exclaimed.

Everyone who was talking looked in the direction of Lao Jiujiu's finger.

Seven or eight billowing smoke rose into the air.

Zhu Yuanzhang looked over.

Zhu Di smiled and explained, "Father, there are various workshops over there. The thick smoke is produced by blast furnace iron smelting and cement burning."

Such thick smoke?

How big is Zhu Silang's blast furnace?

When the officials heard this, they looked at each other secretly.

Zhu Di followed Zhu Yuanzhang's line of sight and looked at the workshop area in the distance.

In the bay, there are usually more winds blowing from the sea.

So the workshop area was built in the downwind position in the deep southwest.

The bay was little affected.

He was confident that the prototype of large-scale industry in the workshop area would definitely give his father a very strong shock.

Let his father truly realize the power of large-scale industry.

"Father, do you want me to take everyone to the workshop area now?"

Zhu Yuanzhang came back to his senses, smiled and shook his head: "Dad will stay in Jilong Island for a long time, it doesn't matter for a while, take us to rest first."

He didn't want to see it hastily.

He had to rest well.

Watch carefully!

It's not easy to come here once, if he doesn't see it thoroughly, he may regret it for the rest of his life.

So, even if he is very eager in his heart, he has to suppress it.

Everyone can only suppress their urgency and follow Zhu Yuanzhang to where they are staying.
