Chapter 969: Leading a Team to Visit and Sell Cement

The next morning, Li Longji still had a low fever, and Li Yi didn't give him medicine.

He drank half a bowl of thick chicken and vegetable porridge, ate some pickles, and went to court, carrying a thermos and a watermelon.

The thermos was filled with light salt water, and the watermelon was naturally a watermelon. Others had no watermelons, and Li's manor could still provide them.

The watermelons in the southern region have come, but distant water cannot quench immediate thirst.

After ten days, the watermelons in Jingzhao Prefecture came, just when the watermelons in Li's manor were out of season.

At court, the ministers talked about the war in Sulu.

"Your Majesty, Sulu led the Arabs and Tubo to send troops, and I think he should be rebuked." The Minister of Rites stood up.

Li Longji looked at him and said, "No need, just beat him."

He was decisive and straightforward. What's the use of scolding? I'll beat you if you rebel, do you think I'm afraid of you?

If you force me into a corner, I'll let my brother Yi take the Yulin Flying Cavalry to capture you alive, do you think I don't have a trump card?

"Your Majesty, I would like to build more ships with a capacity of 100 shi to facilitate the border." Su Yan stood up, and he found the benefits of ships.

"I have something to say..."

Li Longji began to talk about his canal excavation, connecting the Yellow River from the other side.

...

"This is Pujin Ferry. Originally there was a bamboo rope floating bridge, but now it is replaced by iron ropes." Honglu Temple Secretary Liu Tong introduced to the Japanese exchange group.

They came last night and saw the terraced fields planted by more than 220,000 surrendered households.

This morning after breakfast, we were going to Hukou Waterfall. When passing by the iron rope floating bridge, Liu Tong explained.

"Liu Jun, is that cement?" Abe no Nakamaro looked at the bridge and thought it was easy to use and suitable for Japan.

"Concrete, there are steel bars, pebbles, and cement." Liu Tong explained in detail.

"Are you familiar with the method of making cement?" Abe no Nakamaro asked again.

"I don't know. Li's manor is confidential. Lantian County is under military control. Others are not allowed to inquire." Liu Tong glanced at the Japanese.

The people in the Honglu Temple already knew what Li Yi meant. Secrets that should not be disclosed must not be disclosed.

Moreover, he really didn't understand how cement was made. Everyone who made cement only knew his own work.

The Japanese envoys showed regret that they couldn't learn it.

Of course, they understood why they had to keep it secret. Cement can build a city wall quickly, and a city wall can be built in a few days.

According to what Takagi Junichiro said, the Tang Dynasty sent a lot of cement to the border to build a city there to resist the enemy.

Liu Tong smiled secretly in his heart and said, "The method of making cannot be passed on. However, if you want to buy it back, you can sell it. One pound of cement only costs one penny."

He promoted cement according to Li Jiazhuangzi's instructions. Li Jiazhuangzi gave a base price of three pounds of cement for one penny.

There is a little profit, which is said to be 5%.

"Can it be cheaper if you buy more?" Xia Dao Zhenbei thought it was a bit expensive. It's not that he thought the cement was not worth the money, but that he needed too much and had to ship it back to Japan.

Liu Tong nodded: "For 10,000 jin, 3 jin of cement costs 2 cents; for 100,000 jin, 2 jin of cement costs 1 cent; for 500,000 jin, 5 jin of cement costs 2 cents."

He still didn't tell the bottom price. What he knew was that if he wanted to build a city, he would need hundreds of millions of jin of cement.

If the city is bigger, the cement consumption will be even greater.

Building houses in the south of Chang'an City is a mixture of cement and sand.

A normal house, as Li Dongzhu said, is 10 feet high, brick-concrete, and has an area of ​​50 square meters. If you use it sparingly, you can use 500 jin of cement.

If it is reinforced concrete, the same height and area require more than 10,000 jin of cement.

The difference is so big, it depends on where you use the cement.

Now all the houses are built with the cheapest kind, who wants reinforced concrete?

The reinforced concrete foundation by the river is hard poured, and the cement used on both sides of the river is more than 26 million jin.

It is so heavy, so of course less is used for plastering.

But the price is not too high, not as expensive as iron ropes.

Cement costs eight million coins, equal to eight thousand coins. Does that count? Steel bars and iron chains cost more than ten times.

If all are replaced with iron, it costs more than a hundred times. Thanks to cement, money is saved.

Building a city is just plastering, otherwise the amount of cement...

The Japanese don't know the situation. When they hear how many tens of thousands of catties it is, they think they can build a lot of cities.

"Mr. Liu, sixty million catties, twenty million coins." Abe no Nakamaro gritted his teeth and bargained.

Liu Tong frowned and shook his head: "I can't make the decision. This price is too low. I will go back and ask. I will say that the Tang Dynasty and Wa are friendly, so that Li Dongzhu will sell it even if he loses money."

"Please, Mr. Liu." Abe no Nakamaro was very uncomfortable when he heard the word Wa.

A few years ago, they also thought that the name Wa was okay, but later they thought it was discriminatory, so they changed it to Japan.

But the Tang Dynasty called you Wa, you have to accept it even if you are unhappy.

Others also bowed together, hoping that Liu Tong would help more.

In fact, this amount was only 80,000 tons at Li Yi's time. What can 80,000 tons of cement do?

It also needs to be transported back by ship. If it rains, the cement will be soaked by rain...

Even if there is no rain, the sea is humid and the cement is exposed to moisture...

"Everyone, get on the boat. Before the bridge is opened, let's go up and take a boat from the top. It will take two and a half days to reach Hukou Waterfall."

Liu Tong invited 555 people to take a boat. From here to Hukou Waterfall, it is nearly 300 miles, upstream.

It is good to walk ten miles in an hour. If it is changed to the goose boat at Li Yi's time, people can't go far even if they are exhausted.

Not to mention the goose boat, the iron paddle boat takes more than ten minutes to travel two miles, and it is not on the Yellow River.

The Yellow River flows fast, and some work needs to be offset.

If it is put on the Yangtze River, it can go six miles in one hour, which is far better than the boatmen pulling the boat.

Of course, if it is replaced with a propeller and goes up the Yellow River, it is guaranteed to go more than thirty miles in one hour.

After passing the place with turbulent water, the speed can be increased to forty miles.

If Li Yi makes a steam engine...

If he makes a diesel engine...

The Japanese think the speed is good, and they have already drawn a picture and written a description.

The picture they drew is different from the picture drawn by Li Yi, and the difference is big.

Li Yi drew a three-dimensional perspective drawing, and the craftsmen of Lijiazhuang knew how to do it after seeing the picture.

Everyone got on the prepared boat and pedaled by themselves. If they could change people, they would pedal desperately to test how fast they could go.

"Mr. Liu, I heard that there is another kind of boat, which is like flying." Fujiwara Mayang said at this time, and he pedaled quickly with both feet. ＵU Reading www.uukanshu.net

"Yes, there is another kind of boat in Lijiazhuang, which is faster than this one." Liu Tong admitted.

They have envoys here, so it is impossible that they don't know about the amazing ship that day.

"Can we take a look? Lift it up and let's see." Fujiwara no Mayang asked.

Liu Tong shook his head: "No, it's a military and national treasure, Doctor Li will not agree, there is no need to think about it, it's useless to ask the prime minister, it's still useless to ask your majesty."

"Your majesty can't do it? He should be beheaded?" Fujiwara no Mayang said as if I am thinking about the majesty of the Tang Dynasty.

"Kill him, and you make good things for the Tang Dynasty? Do you know how many good things Li Dongzhu has made? Why should your majesty agree to you?"

Liu Tong's face turned ugly, you still want to sow discord, do you know what the relationship between your majesty and Li Dongzhu is?

Your majesty wishes he could hold a court meeting in Li's manor, which is safe and worry-free.

You are a Japanese envoy, why do you have so many things to do?
