Chapter 52 The First Technical Exchange Meeting

(Bill: 15 more.)

Wu Fanghai is very patient, explaining in detail and pointing out the key points, intending to cultivate Zhang Hao's war wisdom.

Zhang Hao also studied hard. He understands that the way of fighting in the practice world, especially the way of fighting in the large army, is by no means simple.

Wu Fanghai used several classic wars as examples to give Zhang Hao the most intuitive understanding of the Eastern Expedition:

But he said that the country of Taihua and the country of Canglan are cheap.

why?

Because people never take the initiative to attack!

As long as they control the trade routes, they will be able to suck up the bone marrow and perhaps the massive resources of the western countries little by little; when the fruit is ripe, they will get the vast land of the west without any effort.

Therefore, they deployed their defenses along Daxue Mountain and Qiufeng Ridge. After thousands of years, this line of defense has really been impenetrable. All kinds of formations and outposts are endless.

The two countries also encourage non-governmental forces to go to Daxue Mountain and Qiufengling for training as much as possible when training future generations.

Many people, big and small families, etc. migrated to farm, breed, mine, etc. at the foot of the mountain.

Under various arrangements, there are almost no loopholes in the border.

Western countries also sent masters to sneak attacks, but after thousands of masters crossed mountains and mountains, they were surrounded by tens of thousands of troops. Several sneak attacks resulted in heavy losses, and finally had to give up the sneak attack.

Wu Fanghai sighed: "In war, there is one thing that will never change, that is: use your strengths to attack the enemy's weaknesses!

So, what are the strengths of our West?

It is a large amount of black iron resources!

We can use black iron to create huge and sharp war weapons. These war weapons can only be manipulated at the Qi refining stage and the foundation building stage; but they can cause fatal damage to the Jindan stage and even the Nascent Soul stage. "

"So, we must launch a large army battle.

Use our masters to hold back the enemy's masters; create opportunities for a large number of grassroots soldiers to win.

This is our way of war.

This is also the most effective way of warfare that Western countries have summed up for thousands of years.

Victory needs to be created by grassroots soldiers. "

…………

Zhang Hao stood in front of the map for a whole night. He didn't collect the map until dawn and returned it to Wu Fanghai.

Such military maps are state secrets.

After sending Wu Fanghai away, Zhang Shengde finally breathed a sigh of relief, but he held Zhang Hao's shoulder tightly, "You are crazy. In two months, five thousand tons of 95% black iron will be delivered to the imperial capital. This... …

Also, we promised others a lot of black iron before, and there are thousands of tons! "

Zhang Hao smiled easily: "Father, if I say that within two months, we can produce 10,000 tons of black iron, would you believe me?"

"real?"

"Of course! But we need sufficient raw materials, and what the city lord provides may not be enough."

"No problem. We can obtain raw materials through the Black Iron Guild."

Zhang Hao nodded, thought for a while and said, "Father, the guild has a function, which is technical exchange. I think it's time to strike while the iron is hot and do a technical exchange to consolidate the Zhang family's position."

Zhang Shengde was thoughtful: "Then what technology are we going to disclose this time?"

"Production "methods" such as ore crushing, spiritual stone crushing, and water separation. The real technology is not disclosed. For example, blasting into molten iron cannot be said."

Zhang Shengde thought for a while, nodded in agreement, and handed Zhang Hao the responsibility.

With the experience of publicizing the water forging technique last time, this time Zhang Hao first conducted an experiment by himself to find out the situation clearly.

…………

At dawn, City Lord Liu Jingming was awakened. Sure enough, the emperor's command came: fully cooperate with the Zhang family to smelt black iron, and supervise the Zhang family. If there is any misbehavior, it can be dealt with cheaply.

…………

In the early morning, the gates of the Xuantie Guild were closed tightly, and those who came to purchase Xuantie met with rejection.

Speaking of which, since the establishment of the Black Iron Guild, although the price has risen slightly, the quality has also improved a lot, and the market has regained order. For the time being, it seems to be a happy scene for everyone.

Moreover, the price of black iron in Ninghe County is still the lowest.

With good quality and low price, there is an endless stream of buyers.

But this morning, the door of the Black Iron Guild was closed, and more than a dozen young masters in the foundation building stage were guarding the door.

Only members of the Xuantie Guild can enter; the rest are not allowed to enter.

"What's the matter?" Liu Xian of Yunying Trading Company was stunned.

Some time ago, the black iron purchased on credit from Zhang's family was about to run out, and they were going to buy it; they were turned away.

"I'm sorry, I'm sorry, senior, please come back tomorrow, okay. Today we have some internal affairs that need to be rectified. I'm sorry for the inconvenience caused to senior." Gongsun Xuan, the young master of Longyun Trading Company, came up and apologized.

"What's the matter?"

"Our internal affairs." Gongsun Xuan continued to accompany the smiling face.

"Okay." Liu Xian left helplessly.

At this time, inside the Xuantie Guild and inside the barrier, there were a lot of people.

Today, the Zhang family will hold the first technical exchange meeting since the establishment of the Black Iron Guild; all members of the Black Iron Guild can participate. There is only one thing, this is an internal technical exchange meeting, and the secrets must not be leaked to the outside world, and I swear.

"Quiet." On the high platform, Liang Siguang, the head of the organization, shouted loudly, "Let us welcome the representative of the Zhang family, Zhang Hao!

Today, Zhang Hao will show us some of the Zhang family's black iron smelting technology. "

Everyone applauded, Zhang Hao walked up to the high platform step by step, bowed his hands in return, and talked eloquently:

"One of the purposes of establishing the Black Iron Guild is to promote the progress of Black Iron technology. To improve technology, communication is necessary.

So today, I will show you the latest Zhang family's black iron smelting method.

For example, how to directly smelt black iron with a purity of more than 60% without forging! "

Swish!

Everyone's eyes suddenly brightened!

Although the water forging technique is good, it still needs to be forged, and the craftsmen are also very hard.

In fact, everyone has a lot of guesses about the Zhang family's black iron smelting technology.

Unexpectedly, the Zhang family would take the initiative to disclose it.

Zhang Hao does things very simply. After finishing speaking, he smiled again and said, "Then, please take care of it."

The craftsmen of the Zhang family came to the stage, and some small smelting equipment was quickly set up. The smelting furnace is only one foot in size - or it is more appropriate to call it a large crucible.

The craftsmen were in an orderly manner, and Zhang Hao was in charge of explaining.

"We believe that there are three main sources of impurities in black iron. In addition to the 'iron' that is usually considered by everyone, there are impurities from the ore itself, and impurities from broken spirit stones of inferior quality.

Then, if we can find a way to remove the impurities of iron ore and crushed spirit stone in advance, we can directly obtain high-purity crude iron. "

"First, we select the highest quality ore."

"Secondly, the iron ore should be crushed, and it is best to grind it into a fine powder."

"Third, water separation, or called flotation. During water separation, stir vigorously. The stone powder is lighter and will be taken away by the water flow; what is left, we call it 'iron ore fine powder', or directly It is called 'iron fine powder'.

Pay attention to the degree and amount of water during the mixing process.

The stirring is light, the water is less, and the effect is not ideal.

Stirring is heavy and the amount of water is too much, which may cause unnecessary losses. "

"After the water selection is over, it needs to be precipitated and dried."

"Then is the spirit stone. In order to smelt high-purity black iron, we use spirit stones instead of non-inferior broken spirit stones. The spirit stones must also be crushed."

"The last is charcoal. The usual charcoal contains high impurities. We use bamboo charcoal instead of charcoal."

"There is also the flame. We replaced the ground fire with the flame stimulated by the spirit stone."

After all, Zhang Hao stood aside, and the craftsmen were nervously busy.

It was quiet below, everyone's eyes were bright, and their breathing slowed down, so as not to disturb the craftsmen.

For a while inside the enchantment, there were only the busy voices of craftsmen.

Unknowingly, for more than two hours, the boiling molten iron was poured into thin pieces of iron, and after cooling, they were distributed to everyone.

Suddenly there was an exclamation.

"61%!"

"It's actually smelting 60% crude iron directly!"

Standing on the high platform, Zhang Hao looked down at everyone from such a perspective for the second time.
