At the beginning, I awakened the Taobao system

"Say!"

Li Shimin said.

Wei Zheng looked back and forth at the cement wall, and finally, he looked at the earth wall and stone wall next to him: "Your Majesty, if my guess is correct, Wu Gonghou will build a stone wall and an earth wall next to the 7K mud wall. compared to.

Wei Chen very much agrees with this.

Cement building a city wall not only has to withstand the devastation of war, but also torrential rain, burning fire, and heavy objects hitting. After all, the enemy has many methods, and only by withstanding various tests can the value of cement be proved. "

Wei Zheng took the lead, and the officials were naturally unwilling to lag behind.

"That's right, the matter of city defense is the most important thing and should not be taken lightly."

"Your Majesty, I propose to immediately flood it with water, set it on fire, and hit it with heavy objects to test the strength of the cement."

"Yes, if the cement has withstood all kinds of tests, it should be rewarded with martial arts. If the cement fails to withstand the test, the next best thing is to build irrigation canals
Dao, martial arts is still meritorious. "

Some officials did not want to offend Chen Yi, so they said in a tactful tone.

Lier is this Lier.

The matter of city defense cannot be careless.

Li Shimin looked at Chen Yi and asked, "You mean it."

"If you mess around casually, I will lose if the wall collapses." Chen Yiman said nonchalantly.

"it is good!"

"Come on, arrange it immediately."

Li Shimin shouted to the entourage, he also thought about how powerful the cement is.

A group of tigers came and went, gathered firewood and set fire to it, flooded it with water, threw stones, pushed wooden piles and hit them with heavy objects, all kinds of methods were used, and the concrete wall still stood firm under the eyes of everyone.

However, the earth wall was flooded with flood water, and its thickness was weakened a lot, while the stone wall was directly pushed down by wooden piles, and the gravel rolled all over the ground.

After a lot of tossing, the ending was completely different from what Wei Zheng had imagined.

He stroked the concrete wall, his face was full of doubts, and he muttered to himself: "I am wondering, how can it be so strong."

"Hahaha, Wei Zheng, Chen Yi has always been reliable in his work, and it's not like you haven't seen his methods before, so you must be convinced now." Cheng Yaojinlang said with a smile.The stronger the wall, the better it can hide his previous embarrassment.

"That's right, this high concrete wall is really extraordinary, it's an excellent thing to build a city wall." Li Xiaogong said.

Unconvinced, Wei Zheng pointed to the spots left by the peeling off of the wall and said, "This cement wall still has flaws. You see, after various tests, it is already full of bumps and holes. The frontier fortress often fights all year round. It won't last long."

"Your Majesty, there are flaws." The official said, supporting Wei Zheng.

Hearing the sound, Li Shimin, Cheng Yaojin, Li Xiaogong and others couldn't help turning to look at Chen Yi.

Although it is said that Wei Zheng's approach is nitpicking, but there are flaws after all, and it has been shining for many years, and it is easy to be destroyed.

"Is this a problem?"

Chen Yi sneered arrogantly, waved to the craftsmen in the distance, and shouted: "Get some cement and smooth this place."

Soon several craftsmen came with fresh cement and applied the cement on the uneven wall in front of Li Shimin and his ministers. Soon the scarred wall, except that the cement had not yet solidified, was completely restored to its original state.

After several craftsmen left, Chen Yi proudly said to Li Shimin: "It takes half a day, at most a day, for the cement to solidify, and the wall is still indestructible."

"That's it?"

Li Shimin looked at the wall in disbelief.

This wall is extremely strong, and the Turkic people may not be able to destroy it if they build a city wall on the frontier.Unless he sieges the city day and night, the speed of destruction is far less than the speed of repair.

In the future, building walls and canals with cement will not be done once and for all. At least there will be no need to manage them for a few years, which will save a huge sum of money for the national treasury.

Wei Zheng.

No more squeaks.

It would be a bit self-defeating to say more.

At this time, Li Shimin's Long Yan was very happy, Cheng Yaojin, Li Xiaogong, Hou Junji and others looked delighted.

Cement can build such a strong wall. When defending the city, it will surely save many lives. Chen Yi's move is definitely a kind act.

"Nephew, the old man is convinced." Cheng Yaojin patted Chen Yi on the shoulder and said.

"Someone is also convinced."

"I can't accept it, I didn't expect there to be such a solid thing in the world."

When the few people were happy, Changsun Wuji said: "Nephew, is the cement good? Can we use local materials?"

Building a city wall is costly, and if local materials cannot be obtained, a lot of manpower and material resources are required.

It will seriously affect the promotion of cement.

"Must!" Chen Yi said.

"Okay, that's great." Changsun Wuji nodded repeatedly.

Folding his body and cupping his fists, he said to Li Shimin: "Your Majesty, I believe that cement can not only repair canals and city walls, but also build houses and roads. This thing must be returned to the Ministry of Industry, and the secret recipe for making it must be strictly protected."

"Your Majesty, not only must it be kept secret, but even the kiln craftsmen should be strictly screened." Fang Xuanling said.

This object has a wide range of uses, and the production method must not be spread at will.

Li Shimin nodded: "It should be done."

"Congratulations, Your Majesty, for obtaining this treasure."

"Congratulations, Your Majesty, His Majesty."

A group of officials rushed forward, clasping their fists in congratulations.

Li Shimin enjoyed the compliments from all the officials, and said proudly: "I said earlier that my good son-in-law is not simple, now you know how powerful he is."

After hearing the news, all officials congratulated again.

Li Shimin waved his hand to stop him and asked, "Chen Yi, after all, what does cement look like?"

"Yes, nephew, I have been here for so long, but I still haven't seen the cement." Cheng Yaojin complained, he wanted to see what the cement looked like
child.

"Hahaha."

"It's not worth mentioning, it's not worth mentioning." Chen Yi looked at the few people and smiled wantonly, signaling to the craftsmen in the distance to bring some cement.

Quiet.

Silent as a valley.

Li Shimin and his ministers stared at the cement that the craftsmen were holding, they were stunned and poked there like half a wooden stake.

Even though they have seen the cement made by craftsmen, they still can't believe it is real when they look at the cement that is no different from fine soil and think about the rock-solid high wall.

drop.

The gap is too great.

Cheng Yaojin's face was as red as sauce, and he tried to convince himself: "Nephew, I think you should be joking?"

This thing, not to mention heavy punches, he can blow it away with one breath.

"Nephew, this is not fun." Li Xiaogong said in astonishment: "A gust of wind can blow all these things away."

"Chen Yi, you'd better not fool me." Li Shimin said blankly.

"Hahaha……"

"It's really cement."

"Haven't you heard that dripping water wears through stones, and sawing wood breaks? Cement looks inconspicuous, and rainwater solidifies like an ice wall."

For a group of ignorant bumpkins, Chen Yi didn't even bother to explain.

At this time, Fang Xuanling came out and said, "Your Majesty, this is indeed cement, and I witnessed the craftsman pouring it with my own eyes."

Shocked.

It was too shocking.

"The high wall is solid, but there is still room for improvement. Before pouring, put some steel in advance, and the built wall will be absolutely rock-solid." Chen Yi said. "Okay!"

Li Shimin chose to believe Chen Yi's words: "My son-in-law, you have made great contributions to this move, and you should also serve as the minister of the Ministry of Industry."

Concurrently serving as the minister of the Ministry of Industry?

All the officials were shocked when they heard the sound.

On the bright side, Chen Yi served as the servant of the household department, concurrently served as Tai Changqing, and a bachelor of Hongwenguan.

With his military talent shown in the Northern Expedition, he will definitely serve in the army in the future, not to mention that Chen Yi has already taken charge of an unknown number of black cavalry.

He also served as the minister of the Ministry of Industry, and his power involved three ministries.

Even if Chen Yi is not greedy for power, his status is still very high.

"Your Majesty, it is true that martial arts can make cement, and it will benefit the future. However, it is not appropriate to serve as the minister of the Ministry of Industry."

"Your Majesty, I suggest that you reward jewels, gold and silver, beauties and horses, and you can no longer be appointed officials."

"Your Majesty, this matter is definitely not a joke. From ancient times to the present, no one has ever served as the minister of the Ministry of Industry and the Ministry of Households."

The six civil servants and generals spoke, hoping that Li Shimin would change his mind temporarily.

"Your Majesty, too much power can easily breed corruption." Wei Zhengjin said that among the officials, he and a few people knew that Chen Yi was in charge of the Shenwu Army, and that Chen Yi's power had penetrated into the Ministry of War.

Li Shimin's expression was displeased, and he said bluntly: "Since ancient times, no one has made cement. My dear friends, whoever has the ability, I will let you hold two positions at the same time."

Today there is cement.

In the future, if Chen Yi comes up with other things.
