Fujiwara Mayang was in a daze for a while, and he felt panicked in his heart and wanted to cry.

Also wanting to cry were the other Wa people who got the newspaper, and they spent a lot of money just to see the process.

In the blink of an eye, Li Yi wrote the method in the newspaper, that money!

How good would it be to wait a few days if you knew this was the case?

"Great, Li Yi has become stupid, he dares to disclose cement technology, we can burn cement by ourselves in Tubo."

The residence of the Tubo people in Honglu Temple, Bo Yan shouted excitedly.

Ishimba, who was next to him, was just as happy at first, he knew how fast he could get cement to build roads and houses.

So many people in Tibet made cement and used it to repair the city.

When he continued to look and saw that the following introduction said that coal was used, he became distressed again.

There is no coal in Tibet, what to burn? Wood?

The cement kiln in the newspaper is burned with firewood, which does not seem to work, and the structure of the firewood kiln is different.

"Blah, blatan, look back." Isimba said to Berber, who was grinning there.

"Huh? Yes! What do you think about Li Yi, he dares to release the secret cement manufacturing method, I'll see how to do it. ”

Bo Yan is still so happy, keep watching, see, see.

His smile faded, and his brow began to furrow.

"Hmm~~" After reading it, he made a long sound from his nose and clenched his fists: "Li Yi!" ”

At the same time, many people were sighing, they were envoys from various places.

In fact, including the envoys of the Japanese state, they learned and now found that there is no coal, so they can only use a lot of firewood to burn.

Junichiro Takaki knows the difference between coal and firewood, coal can be burned for a long time at a time, and firewood needs to be added constantly.

Coal coke is better to use, and if you use wood, you can only use a lot of dry coarse chopping wood or coarse charcoal.

Instead of spending so much effort to burn cement, it is better to burn bricks.

"Coal, why don't I have coal in Japan?" Abe Nakamaro is sad, Japan is short of things, and there is so much coal in Datang, Japan can't see it at all.

He didn't know, someone knew where he had a coal mine, Hokkaido.

Now it's not called Hokkaido, and at the same time it's not under their control, and it's very cold in the local winter.

"You can burn firewood, you can burn porcelain, let alone cement. Ask other nations to pay tribute. ”

Fujiwara Mayo thought of the emperor to give an order to tell the other feudal countries to attack cement.

With cement to repair the city wall and roads, at least the road surface of Pingchengjing should be repaired well.

Learn the Chang'an of the Tang Dynasty, and then learn the entire Jingzhao Mansion.

At about the same time, the envoys in other places thought of the same method, as long as there were enough people, what were they afraid of?

The rich people in Chang'an City were tempted to read the newspaper and allowed themselves to burn it?

Coal words, there is, there are a lot of them.

In addition to the coal specially given to the Li family Zhuangzi and the imperial court, the rest was sold, bought with money, and sold after the cement was burned.

It's just that the requirements are a bit much, and the requirements are the same as the previous lime kilns.

People must wear masks and have rapeseed oil on hand.

When the ash gets into the eyes, it needs to be rinsed with rapeseed oil, and it is not allowed to be washed with water.

At the same time, wear hats, tight clothing, gloves, and boots for the people who work and try not to let the skin contact for a long time.

Otherwise, if they are caught, the government will arrest people, confiscate the kiln, and fine money.

This is all cost, a piece of clothing is a lot of money, the key is that the wear is large, there must be a change of washing.

Masks are even more, gloves always work, how long can they last?

"It's finally released, send people to the front line with technology and money, and let the front line look for the coal mine provided by Xiaoyi."

Bi Gou looked at the newspaper in the government hall and knew that it had begun.

In order to occupy the Yellow River Basin, the recipe was announced, and everyone could burn it themselves, without having to keep it official secret.

There will be more wealthy people to invest in building kilns, and people will also be able to use cement.

The steps of the mountain road with cement are more convenient than stones, and if the stones are not large, small gravel, they will break if you step on them.

How can it be convenient to transport cement when transporting large blocks? Add pebbles and sand, mix together, and it is strong and fast.

"How does he know so many mines?" Su Ying was still pondering the question of where Li Yi's ability came from.

"He knows it's not good?" Bi Gou didn't think about it at all, it didn't make sense.

He just needs to know that Li Yi is a native of the Tang Dynasty, and he won't think about being an emperor.

"The Yellow River Basin." Song Jing looked at the map on the wall and muttered.

On the wall there is now a map from Longyou to Sister Lake, and there is an introduction text next to it.

Talk about the local climate, the average altitude, the plants, the animals, the lifestyle of the locals, the difficulties they will encounter in life, etc.!

This was added later, Bi Gou was embarrassed last time, so he hurriedly learned from Li Yi, that is, he asked Li Yi to write a booklet and send it over.

Li Yi also sent a picture to the Yulin Flying Riders and pasted it on the wall of the political affairs hall, and the people in the political affairs hall must learn all of them.

It is necessary to know what the situation is in the place of war, and not to ask questions and not to know anything.

Among them, there is an introduction to coal, but I didn't say where it was, for fear that someone would read it and spread it.

Wait for it to be occupied, and then provide it, and then build a kiln directly from there, and burn whatever you want.

"Shu Road is difficult, use cement." Bi Gou said another use.

"It's okay to go up and downhill, but the plank road can't be used. Instead, it was taken out to make piers, and it was possible to tie iron chains to build suspension bridges. ”

Su Ying thought of the pier of Pujindu and saved a lot of iron.

If the bridge is close, shoot it with a bow and arrow with a thin rope, and connect a thicker rope to one end of the thin rope, and the rope gradually thickens.

Then put the bamboo tube on a thick rope, hang the iron chain on the bamboo tube, pull the bamboo tube, and the iron chain will be pulled over.

One end is fixed first, and the other is tightened with a winch, which is also fixed.

If you are far away, you should go down the rope first, and if there is a river below, you will send it by boat, and if there is no river, you will walk over.

Then climb the mountain, or throw the rope on the opposite side to bring the rope on this side.

It doesn't seem to be needed now, there are hot air balloons, wait for the wind to be good, put a thin rope on the hot air balloon and fly over.

"I wonder if I can build piers with cement? If feasible, the Yellow River will be built in the river when it reaches the dry season. Song Jing thought about repairing the bridge.

The suspension bridge is not as easy to use as the bridge with piers, he thought that the cement was the same, and he did not know that Li Yi wanted to repair the piers, and there would be other cement.

"Ask Xiao Yi, can you repair it in Pujindu? Winter! "Bi Gou is going to try, let's take a look first.

The distance is a little closer, the water is a little shallower, and then ......

He didn't know what to do next, but he usually piled up with stones, one pier after another.

In some places, the water is dry, and in some places, it is necessary to temporarily block a little river, build a pier, and block a position.

So is it necessary to make a pier out of cement first and send it over by boat? How many piers? How big is the ship?

How many hand hoists are used when hanging? Will it be flipped over?

Bi Gou is a question mark about repairing the bridge, he is not professional, he wants to repair the bridge, he can only find someone from the Ministry of Works.

It is estimated that Li Yi will take the time to ask.
