The men of the engineering battalion were already in place, rushing to work during the day and resting at night.

During the break, I also went to night school first, and the instructor did not change.

The king of a country, who personally built a city in the suburbs, participated in the construction of the new capital, and gave great encouragement to the people of the engineering battalion.

The official family who lived on Gaogang was no stranger to them, and they once led them to win the Youyan War three times and destroyed the invincible Jurchen Jin Kingdom.

He would eat around the campfire with everyone, laugh heartily because of vulgar country slang jokes, and occasionally brag about the soldiers around him.

It was he who single-handedly raised the treatment of soldiers, so that when everyone risked their lives to fight, they had a reason to persuade themselves to die for the country.

The suburbs of Hebei, dotted with stars, are as bright as fireworks that will never dissipate in the sky.

In a hammock, Yang Lin pillowed his hands, looked at the stars in the sky, and walked through the recent events in his mind.

Bai Shizhong's reform this time, he has fully agreed, and it is bound to make Great Xia go further; Fang Qifo is still chasing and killing Tusi, will it be too much, when the whole world is bathing in the prosperous world, Qianzhong is still a bloody storm; When the civil war in Goryeo subsided, he needed to pay close attention to the direction of the two forces; Yelu Dashi won another battle, and after this grandson sold the Song army once in Yunnei, he swept away the decline of repeated defeats before, and swept the West like a hanging...

It was easier to come up on this dragon chair, because he was in control of the army, but after sitting on it, there were more troubles.

You can't learn from Zhao Ji, create a prosperous world in the capital, eat, drink and have fun.

The affairs of Goryeo can only wait and see, waiting for the final pattern of the peninsula to be formed.

And the Liao people in the west, the business is prosperous, if the Yelu big stone thief is not dead, and wants to fight back to the east, he has to make plans in advance.

After all, the birthplace of the Liao people has become today's Changchun Prefecture, and cities and buildings are being built.

When he was pondering, there was a burst of laughter next to him, and when he turned his head, he saw that it was a few little palace maids, playing a chess and card game.

This is the invention of Li Qingzhao, the female lifter of the Jinshi Pavilion, which is most loved by the female dependents of large families, and the spiritual entertainment and pastime of this era are still too scarce.

A wealthy society actually needs people like Li Qingzhao and Li Bai, who are full of talent, unbridled poetry and creativity, which can diverge people's spiritual emptiness after they have eaten and drunk.

The star chasing of later generations is probably the same, but compared with Li Bai and Li Qingzhao, the stars of later generations are a little far behind.

A light breeze blew, making Yang Lin hum comfortably, and crossed his legs to look up at the starry sky in the hammock.

"What's in charge, according to what I think in my heart, building a prosperous world is."

When he got up early in the morning, Yang Lin heard a commotion outside.

It is said that the emperor is here, there should not be such a discordant thing, after Yang Lin washed up, he came to the city that had begun to be built below.

The two groups of people quarreled inextricably, but the people around them surrounded them and listened to their quarrels.

After Yang Lin came, he figured out that it was two groups of people who had a disagreement over the use of materials.

When the construction camp built the city, the walls were built with mud or stone.

There are some people who change the materials without authorization, resulting in the joints of the city wall being unable to be fixed.

Yang Lin stopped the quarrel and took people to see the connection, there was a city wall that was obviously stronger and had no gaps.

Yang Lin paused for a moment, and immediately thought that this is the prototype of cement, right?

With the lesson of the last firecracker, he didn't have a lot of hope this time.

In Yuyan's military school, someone mixes lime and clay to make building materials that can be quickly fixed and molded.

Yang Lin asked with interest, "Who made this and what is its name?" ”

"Back to the official's house, this is made by Dean Yang Tianci of the Wubei School, because this thing needs to be mixed with water and soil, so it is called cement. And because it is dried and hardened, the color is blue-gray, some like the volcanic ash of Tianchi, so it is named Tianchi cement. ”

Yang Lin felt the light on his face, and said with a smile: "I just don't know how hard it is?" ”

The ordinary engineers around were all a little disdainful, and the traditional materials they used for city construction didn't really believe in this kind of gray thing.

Youyan came out of the military academy, very confident, and said loudly: "The official family can let us each build a wall to come out, and then use the siege equipment in the army to try the degree of solidity, and you will know." ”

His words were so arrogant that the other engineers were very dissatisfied, and Yang Lin was happy to see this kind of competition.

He waved his hand and said, "Today, I will give you a testimony to see if this Tianchi cement will work." ”

A hundred and ten men were chosen on each side, and in the open field, they began to lay the foundations and build the walls.

After the third day, a simple small wall is piled up, slightly dried, and when the ordinary earth is formed, the competition begins.

The early morning sun was very comfortable, and Yang Lin sat under the Luo cover under the tree, and specially instructed that there was no need to hold an umbrella and bask in the sun.

In front of him was a wooden table, and after sitting down, he was accompanied by Concubine Xian Guiyi and Xiu Lingyun.

Yang Lin was full of interest, and the two concubines were also curious, and the people below were naturally full of strength to prove themselves in front of the emperor.

In the distance, the people of the new army in Beijing were divided into two teams, handling crashes and explosives, preparing to break the wall.

Yang Lin smiled and planted the order flag in his hand, "Little Peach, you go and give the order to start!" ”

Chong Guiyi's eyes lit up, he got up, and hurriedly stepped forward to raise the order flag and waved it vigorously.

As soon as the horn sounded, everything was decent, and the elite of the new army in Beijing first used a crash car and began to hit the city wall.

Neither wall collapsed, but the dirt wall was more damaged.

Immediately after that, someone stepped forward and immediately used explosives.

Yang Lin hurriedly took the two little concubines into his arms and helped them cover their ears.

A loud explosion sounded, and the walls of ordinary dirt were in tatters, but half of the cement of Tianchi was still standing.

Yang Lin stood up and clapped his hands, this cement is made. The other officers and men of the engineering battalion were also very excited.

They argued not for their own sake, but because they felt that this unsightly earth would delay the progress of the walls.

Since there are better raw materials, my own work is easy to do, and the quality is still high.

In Yang Lin's heart, the most important significance of this matter is not to build the city wall of the new capital, but to finally build roads.

"Youyan Wubei School, making this Tianchi cement is really a great achievement. Immediately sent an order for Yang Tianci to come here, and I wanted to ask him how to produce this thing. ”

The principle of cement is very simple, and Yang Lin's first class after accepting apprentices is to take the disciples to see the lime workshop.

Lime and cement are available, and the future of Daxia will have a new look!
