The next morning, Li Longji still had a low-grade 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 the court, carrying a thermos and a watermelon.

There is light salt water in the thermos, and watermelons are naturally watermelons, and no one else has watermelons, and Li Zhuangzi can still provide them.

The watermelons in the southern region have come down, but far from quenching their thirst.

After waiting for more than ten days, the watermelons in Jingzhao Mansion came down, and it happened to be the watermelon garden of Lijia Zhuangzi.

In the last dynasty, the ministers said that the war in Sulu was in place.

"Your Majesty, Sulu led the Great Food and Tubo to send troops, and the ministers thought they should be reprimanded." The waiter of the Ministry of Rites stepped forward.

Li Longji glanced at him: "No need, just hit him." ”

He is decisive and crisp, what's the use of scolding? If you rebel, I will beat you, when I am afraid that you will not succeed?

I was forced to be in a hurry, I asked Brother Yi to take Yulin Fei to ride over and capture you alive, when I didn't have a killer feature?

"Your Majesty, please build more ships with 100 stones to facilitate the border passes." Su Ying stepped forward, and he found the benefits of the ship.

"I have something to say......"

Li Longji began to say that his canal was dug to connect the Yellow River from the other side.

……

"This is Pujindu, there was originally a bamboo cable pontoon, and now it is replaced by iron cables." Honglu Temple Cheng Yanagi Tong was introduced in the exchange group with Japan.

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

I had dinner early this morning to go to Hukou Waterfall, and when I passed by the iron cable pontoon, Liu Tong explained.

"Liu-kun, that's cement?" Abe Nakamaro looked at the bridge and thought it was easy to use and suitable for Japan.

"Concrete, with steel bars, pebbles, cement." Liu Tong elaborates.

"Is Liu Jun familiar with the method of cement production?" Abe Nakamaro asked again.

"I don't know, the Li family Zhuangzi keeps it secret, Lantian County is under military control, and others can't inquire." Liu Tong glanced at a circle of Japanese people.

The people of Honglu Temple already knew what Li Yi meant, and the secrets that should not be leaked are absolutely not allowed to be revealed.

What's more, he really doesn't know how cement is made, and everyone who makes cement only knows his own work.

The envoys of the Japanese state showed regret and could not learn.

Of course, they understand why they should keep it secret, the cement wall is built quickly, and it is a city wall in a few days.

Listening to what Junichiro Takaki said, Datang sent a lot of cement to the border pass, and wanted to build a city there to defend against the enemy army.

Liu Tong smiled secretly in his heart, and said: "The method of production cannot be passed on. However, if you want to buy it back, you can sell it, and you only need one penny for a pound of cement. ”

He sold cement according to Li Zhuangzi's instructions, and the reserve price given by Li Zhuangzi was three catties of cement per penny.

There is a little profit, say five percent.

"Is it cheaper to buy more?" Shimodo really thinks it's a bit expensive, not that the cement isn't worth the money, it's that it takes too much, and it has to be shipped back to Japan.

Liu Tong nodded: "10,000 catties, three catties of cement for two dollars, 100,000 catties, two catties of cement for one penny, 500,000 catties of cement for two catties." ”

He still didn't say the reserve price, what he knew was that if he wanted to build a city, it was not enough to have hundreds of millions of catties of cement.

If the city is larger, it consumes more cement.

To build a house in the south of Chang'an City, it is a mixture of cement and sand.

A normal house, according to what Li Dongzhu said, is one zhang high, brick and concrete, with an area of 50 square meters, saving some use, 500 catties of cement.

Replaced with reinforced concrete, the same height and area, more than 10,000 catties of cement.

The gap is so big, it depends on which you use the cement.

The houses are all the cheapest now, who wants reinforced concrete?

The reinforced concrete base by the river, hard poured, added up on both banks, used more than 26 million catties of cement.

It's so heavy, of course, it's less used for plastering.

However, the price is not too high, and it is not as expensive as the iron cable.

Eight million dollars for cement, which is eight thousand yuan, is that money? Steel bars and iron cables, more than ten times.

It's all replaced with iron, more than 100 times, thanks to cement, saving money.

To repair the city is to plaster, otherwise the amount of cement is ......

The people of the Japanese country did not know the situation, and as soon as they heard how many thousands of catties, they felt that they could build a lot of cities.

"Liu Jun, sixty million catties, twenty million dollars." Abe Nakamaro gritted his teeth and bargained.

Liu Tong frowned and shook his head: "I can't be the master, this price is too low, I want to go back and ask, I will say that Datang and the Japanese are friendly, let Li Dongzhu sell it even if he loses." ”

"Please, Liu-kun." Abe Nakamaro was very uncomfortable when he heard the word "Wakoku".

A few years ago, they themselves thought the name Wakoku was appropriate, but later they thought it was discriminatory and changed it to Japan.

But people call you Wa Guo, and you have to admit it if you are unhappy.

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

This amount was actually 80,000 tons at Li Yi's time, what is 80,000 tons of cement enough for?

It will also be transported back by boat, in case it rains, and the cement will be drenched by the rain......

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

"Everyone, get on the boat, before the bridge is opened, let's go up, take a boat from above, 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, nearly 300 miles, against the current.

It's not bad to walk ten miles in an hour, but if you change to Li Yi's goose boat at that time, you can't run far if you're tired.

Needless to say, the goose boat and the iron paddle boat take more than ten minutes for two miles, not on the Yellow River.

The Yellow River flows fast, and it needs to offset some of the work.

On the Yangtze River, if you can go out for six miles in an hour, it is far more than the slender man.

Of course, if you change to a propeller and go up the Yellow River, you will be guaranteed to be more than 30 miles in an hour.

After passing the place where the water is fast, the speed can be increased to forty miles.

If Li Yi gets the steam engine out......

If he made a diesel engine......

The Japanese thought that speed was good, so they had already drawn the drawings and wrote the explanatory text.

The pictures they drew were different from those drawn by Li Yi, and the gap was huge.

Li Yi painted a three-dimensional perspective, and the craftsmen of the Li family Zhuangzi knew how to do it when they saw the picture.

Everyone got on the prepared boat, pedaled by themselves, and could change people, so they pedaled as hard as they could, trying to see how fast they could go.

"Liu Jun, I heard that there is another kind of boat, which is the same as flying." Fujiwara Mayo spoke at this time, and his feet kicked quickly.

"Yes, another kind of ship of the Li family Zhuangzi is faster than this." Liu Tong admitted.

There are envoys here, and it is impossible not to know the ships that amazed the audience that day.

"Can I wait and see? Lift it up and see. Fujiwara Mayo asked.

Liu Tong shook his head: "No, the military is heavy, Dr. Li will not agree, there is no need to think about this matter, it is useless to find the prime minister, it is still useless to find Your Majesty." ”

"Your Majesty is not successful? Should he be killed? Fujiwara Mayo said with a look of me thinking about His Majesty the Tang Dynasty.

"Kill him, you make something for Datang? Do you know how many good things Li Dongzhu has made? Why did Your Majesty promise you? ”

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

His Majesty hates to hold a court meeting in Li's Zhuangzi, which is safe and worry-free.

You are an envoy of the Japanese kingdom, why are there so many things?
