Tai Chi Temple.

Cheng Yanjin jumped out at once and said loudly: "Your Majesty, the border fortresses are all dilapidated, and they must be repaired, otherwise the soldiers can only carry them with flesh and blood, and they are all good sons of our Tang Dynasty!" ”

Fang Xuanling said: "Your Majesty, the treasury is tight, and there is not much money and food that can be transferred. ”

Wei Zheng said: "Your Majesty, the amount of all the repair works is too large, and the people need to rest and recuperate soon." ”

Cheng Biting Jin said: "The world is peaceful and the Turks are eyeing each other, can you make the world peaceful?" ”

Wei Chigong came out and said: "That is, the Turks in the north will go south at any time, so you must be on guard!" ”

……

"Alright, stop arguing!" Li Shimin said helplessly, in fact, these are all clichés, everyone understands the situation on the border, and everyone understands the tension in the national treasury.

The border fortress needs to be repaired, and the treasury is tight and can't allocate much food, so it can only choose the most important fortress that needs to be repaired for repair.

Li Shimin muttered: "Let's come up with a plan first, how much grain can be allocated, and those fortresses need to be repaired the most." ”

Cheng Yanjin said with a big grin: "It's so troublesome, it will be repaired in ten days and half a month by using local materials, how much more money can it cost." ”

Suddenly, the entire hall fell silent, and everyone looked at Cheng Yanjin as if they were looking at a fool.

It was repaired in ten days and half a month? You're going to repair a latrine, huh?

The biggest reaction was Tang Jian, the secretary of the Ministry of Industry: "Cheng Zhijie, are you dreaming?" Can you repair a fortress in ten days and half a month? How many people do you have to mobilize? Or local materials? What kind of materials are taken locally? ”

Cheng bit his neck and said: "As long as limestone and clay are enough, and there is no need to mobilize the people, ten days and half a month are enough!" ”

There was silence in the hall for a while, and then it exploded, they didn't expect Cheng Yanjin to say such an ignorant thing.

It shouldn't be, Cheng Yanjin is a well-informed person who travels south and north, how can he say such a stupid thing that is not boundary?

Could it be that Yu Chigong was stupid?

Wei Chigong and other generals were also a little stunned when they looked at Cheng Yanjin, under normal circumstances, they were in a group, but now they didn't know what to say, because they also felt that Cheng Yanjin's words were too inconsequential.

You really would be taken for a fool.

Tang Jian said speechlessly: "Should you repair the city wall or paste the wall?" We also use only limestone and clay from local materials! ”

Cheng Biting Jin said loudly: "I, Cheng Biting Jin, have experienced a hundred battles, and you can't be an ignorant child when I am a child?" Limestone and clay can repair the walls, and they are very strong! ”

Tang Jian said categorically: "Impossible! ”

Cheng Yanjin snorted: "That's because your Ministry of Industry is stupid and can't do it!" Just because you won't know it doesn't mean that others won't! ”

Tang Jian suddenly jumped to his feet and said, "What? Are we stupid? Do you have the ability to repair it with clay and limestone to show us? ”

Boom!

Li Shimin, who was sitting on the throne, slapped it on the imperial case, and the hall suddenly fell silent.

"Cheng Zhijie, can you really use clay and limestone to repair the city wall?" Li Shimin asked, with a hint of excitement in his voice.

If you can repair the walls with only clay and limestone, it will be very significant! That means you don't have to go far to mine stone, you don't have to have to go through difficult transportation, you don't have to recruit people, and you don't have to spend a lot of money!

Cheng Yanjin hurriedly bowed down and said, "Your Majesty, it's not Chenneng, it's Su Chengneng!" ”

Su Cheng?

This voice fell in the hall and immediately aroused a burst of discussion, this name is very familiar to everyone, because Su Cheng has become famous in Chang'an in recent days.

This is a great talent! He wrote a few poems that will go down in time!

Moreover, this man also found rice seeds that can be harvested twice a year, made great contributions, and was named Ankangbo by the emperor. Of course, everyone thinks this kid is shit lucky.

However, there is no doubt that Su Cheng is a great talent.

Of course, there are also some people who know that Su Cheng brewed a good wine with burning knives.

Is there any other way for this kid to repair the walls out of clay and limestone?

Everyone shook their heads slightly, clay? Limestone? It's not a solid thing, how can it be used to repair the city walls?

Repair the walls with clay and limestone, but after a rain of arrows, the walls will collapse! This is not a joke, this is related to the life and death of countless soldiers!

"Su Cheng?" Li Shimin muttered softly, he didn't expect Cheng Yanjin to mention Su Cheng, which means that Su Cheng had a way to repair the city wall with clay and limestone?

If it was Su Cheng who said it, it would be much more reliable than what Cheng Yanjin said! After all, Su Cheng's kid is a bit weird, his master's origin is mysterious, and Su Cheng's kid's methods are also a little mysterious.

Regardless of whether the gods are mysterious or not, if you can really repair the city walls with clay and limestone, it will definitely be a great achievement!

Li Shimin felt both anticipation and nervousness in his heart, and said loudly: "Xuan'an Kangbo Su Cheng will see you!" ”

Su Cheng stretched his waist and walked out of the bedroom, still carrying two belly pockets in his arms, he was a little strange, what about Cheng Biting Jin?

Why didn't Cheng Yanjin come to him?

Because of Cheng's gold-biting temperament, he would definitely go to the emperor in a hurry, but Su Cheng didn't expect that there would be no movement at all.

Do you not believe that he can repair the walls of clay and limestone?

Clay and limestone make cement, and clay can also make red bricks, and that thing can definitely repair a city wall!

Not only can the city wall be repaired, the cement and red bricks can be used to make the boss, and the bridge can be repaired, paved and built a house, which is definitely a earth-shaking change for Datang!

This means a lot more than distilled spirits!

It's just a pity that you may not see the antique mansions in the future, and there are blue brick houses everywhere......

Just when Su Cheng was thinking about it, Cheng Chumo hurriedly walked over with his group.

"Su Cheng, hurry, the emperor summons you!" He shouted excitedly from the old distance, his tone was full of envy, although he could often see the emperor, but it was all thanks to his father, and he had never taken the initiative to be summoned by the emperor.

But Su Cheng was summoned by the emperor again and again, and he was often beaten by the emperor, which was really enviable.

Su Cheng looked up at the sun in a bit of confusion: "Isn't it the time for the early dynasty?" ”

Father-in-law Yao said repeatedly: "Oh, Uncle Ankang, you should hurry up, the emperor and the hundred officials of cultural relics are still waiting in the main hall!" ”

When he saw Su Cheng for the first time, Gonggong Yao concluded that this kid was dead, but under the forty boards, this kid not only did not die but also jumped alive, and now he has become an uncle.

Of course, what shocked him even more was that this kid beat Princess Gaoyang's ass yesterday, and he is still like no one.

I can't afford to mess with it!

So Yao's attitude is still very respectful.

"But I haven't eaten breakfast yet!" Su Cheng touched his stomach and muttered.
