Li Shimin turned around and left, and above the main hall of Taiji Palace, only Li Chengqian and Yu Wenshi and two people existed.

Li Chengqian said unceremoniously: "Yu Wenshi, this king has persuaded you, but you are still against this king!" ”

Yuwen Shiji said: "What His Royal Highness the Crown Prince said, the minister doesn't understand, the minister is just thinking about the Tang Dynasty, not against you!" ”

"Whether you are right or not, you know it very well in your own heart, and you will not elaborate on the specific king. With His Majesty supporting you at the moment, you will be fine, but you will not know in the future. ”

"His Royal Highness the Crown Prince doesn't understand!"

"Don't pretend, you're so exposed."

"The heart of the minister, dedicated to Datang, as long as Datang is good, the minister will naturally follow the good direction of Datang! Please also ask His Royal Highness the Crown Prince not to discredit Yu Chen! ”

Yu Wenshi became more and more difficult to deal with, no matter how Li Chengqian scolded him, he did not admit to going against him.

"Well, don't let this king catch the handle, otherwise it will be the same as Liu Hongji, which is equivalent to being exiled, and the worst will be ...... Hang your head above the city gate for future generations to spur! ”

Li Chengqian dropped this sentence and went outside to wait for Li Shimin, which made Yu Wenshi and a little shuddered.

But when he left, Yu Wenshi said coldly: "At the moment, it is Your Majesty's Tang Dynasty, you are a prince, what big waves can you make?" I don't believe it, you can cover the sky with one hand! ”

Li Chengqian walked out of the hall and looked at the sky, it was already close to noon.

I am afraid that I will not be able to return to the East Palace in the afternoon, so I will attract a small yellow door.

"You go back to the East Palace, talk to Guan Lishi, and say that this king will not go back, so let Wu Jue not wait for this king!"

"Yes!"

After Xiao Huangmen left for a while, Li Shimin also walked out of it.

"Let's go, you go with me."

"Your Majesty, I don't know where the problem is?"

Li Chengqian asked.

"The city wall on the east side, the last flood washed away a large part of the wall, and the Ministry of Works repaired it several times, but it was not in the best situation, I want to go and see what is going on. What are these people doing. ”

The city wall of the Tang Dynasty was covered with bricks on the rammed earth, and then a layer of mud and pebbles was laid on the rammed earth, and then bricks were laid on it.

In the late Tang Dynasty, both sides of the city wall were brick walls, with different brick specifications, including pattern bricks in the Han Dynasty and plain bricks in the Tang Dynasty.

There is scattered water on one side of the outer wall, and the paving is neat, divided into two construction methods: oblique paving and tiling, and the outer side of the scattered water is fixed with Ding bricks.

This method of wall cannot withstand wind and rain, especially when it rains heavily, and it is very difficult to repair if the foundation is not strong.

And the top of the ground defense is also inferior to the modern city wall.

Li Shimin said that at this time, Li Chengqian had a thing, which may be very useful, and its appearance may affect the architecture of the entire Tang Dynasty.

That's right, this thing is cement, if it appears, then Datang's houses will be able to be built higher, maybe some high-rise buildings can be built, then more people can live, and it is not impossible to forcibly pull Datang to modernization.

"Let's go, the people from the Ministry of Engineering have been waiting there for a long time!"

Li Shimin said, and after finishing, he walked to the front.

The group waited, and then headed for the east gate.

At this time, the place has been emptied, and there are no idle people waiting to haunt it.

Duan Lun, the secretary of the Ministry of Industry, saluted Li Shimin as soon as he saw him coming.

"Greetings to Your Majesty and His Royal Highness the Crown Prince!"

"Don't be polite, tell me what you're going to do next? About that wall! ”

Li Shimin pointed to the wall on the side, which had collapsed at this time, and some of it was still being repaired, so it was not completed so quickly.

"Your Majesty, because of the flood, the city wall is a little fragile, and after the foundation is soaked in water, it can't be forced, so it is a little difficult to repair, so I think it can be rebuilt again!"

As soon as these words came out, Yu Wenshi, who let him aside, say: "If this is the case, the next time the flood comes, won't it have to be rebuilt again?" Is there a one-size-fits-all solution? ”

He's right, that's what happened, what if next time?

What should I do next time?

"Yes, what if there is a next time? I'm afraid you don't have to do it anymore! ”

Li Shimin's face was gloomy.

But this is not to blame Duan Lun, the current level of craftsmanship is like this, and there is no way to do the best.

"Your Majesty, let your sons do this, and ensure that it will not be damaged for a hundred years! Forever for a thousand years! ”

Li Chengqian looked at the surrounding walls and said.

"His Royal Highness the Prince, that's not a joke, this place is not simple!"

Duan Lun said, and at the same time whispered: "His Royal Highness the Prince, this is the fault of the minister, you still don't want to muddy the water, in case someone gets in the way, then what should I do?" ”

Sure enough, the Yu scholar found an opportunity.

directly said: "His Royal Highness the Crown Prince must have a way, if you can really create a thousand-year-old eternal existence, it will be the luck of the Tang Dynasty, Your Majesty, the minister thought that this matter would be handled by His Royal Highness the Prince!" ”

He wished he wanted to make Li Chengqian make a fool of himself, so that he would have a way to join him.

This time, Li Chengqian will definitely be pulled off the horse.

Yu Wenshi thought with hatred in his heart.

"Gao Ming, what do you think?"

Li Shimin asked curiously.

"Your Majesty, Erchen wants to build a kind of city wall that is difficult to break even by trebuchets!"

As soon as he said this, everyone was shocked, as far as they knew, it was impossible.

"Since His Royal Highness the Crown Prince can make it, then without further ado, it is better to start today!"

"Yu Wenshiji, are you an immortal when you are the king? Come on? Is it okay to use some brains? ”

It was said that the Yu scribe was speechless for a while.

"Gao Ming, how long will that take?"

Li Chengqian didn't think about it, and said directly:

"In three days, Your Majesty will be able to see all this!"

Three days? What can you do in three days?

There's not much you can do in three days.

When Li Shimin heard this, he said:

"Okay, in three days, I want to see how you do it, if it's really like what you said, then our city is really impregnable!"

It is naturally the best to solve the problems of people's livelihood, and Li Shimin is naturally overjoyed in his heart.

"That's for sure!"

Duan Lun looked at Li Chengqian, and felt a little reluctant in his heart.

He asked in a low voice, "His Royal Highness the Crown Prince, is it really possible?" ”

"Naturally!"

Yu Wenshi and said: "If it can't be completed in three days, what should it do?" ”

Li Chengqian smiled

"How? Naturally, His Majesty will deal with it, and this king still needs to report to you? ”

Frightened, Yu Wenshi and said again and again: "Your Royal Highness the Prince, the minister didn't mean that. ”

"It is better that this courtier is not above the king, for that will not do you any good."

Yu Wenshi bowed his head and said nothing.

After eating the turtle this time, Yu Wenshi and thought in his heart that next time Li Chengqian couldn't finish it, he must take a good look at him.
