Li Shimin did not ask about the role of these gaps, in his opinion, these gaps should be left during the construction of convenient construction, of course, Li Ke can not say that this thing is an expansion joint, specifically left to prevent road cracking, an explanation has to explain what is thermal expansion and contraction, too troublesome, Lao Li does not need to know so much.

"After renovating Chang'an City, can this thing be used to build other buildings?" Li Shimin asked again.

"Of course, there are many advantages to building with it, for example, some wooden houses are prone to fire and burn down completely after they catch fire, but concrete buildings are at least not a problem in terms of fire protection."

"In addition to the bridge, Erchen is going to find some experts in bridge research after the cement research is out, and he is going to find some experts in bridge to build a bridge across the Yellow River." Li Ke began to brag again.

With cement and concrete, plus steel can theoretically build a bridge across the river, such as the way the Wuhan Yangtze River Bridge in later generations, it can be built, but that thing is not something that Li Ke can play with now.

Li Shimin was speechless, he didn't know that Li Ke's words were true, the bridge across the Yellow River? How dare you think about it.

"Okay, then you can continue." Li Shimin waved his hand and said, "By the way, I will remember the last dynasty in three days." ”

"Yes, it just so happens that Erchen also has something to do." Li Ke said very simply.

"Alright, go back to the palace." After reading the road, Li Shimin didn't bother to look at Li Ke, he was still angry, hum!

However, the eldest grandson Wuji next to him gritted his teeth, arched his hand directly at Li Ke, and said expressionlessly: "The old minister will send someone to prepare all the goods and house deeds of the cloth and grain stores in Chang'an City to the palace of His Royal Highness the King of Shu today. ”

"Thank you uncle, the elder didn't dare to resign, but the nephew was disrespectful." Li Ke smiled with a smile on his face, and directly bent down and arched his hand.

The eldest grandson Wuji has already done a good job in psychological construction, losing is losing, it's not a big deal, although there are a lot of these two lines of cloth, there are seven or eight in total, but it is not the main business of the eldest grandson's family, that is, the deed is worth money, he can not care about this money, mainly because he calculates others all the year round, but he was calculated by Li Ke, a reckless man, and the eldest grandson Wuji is a little unbearable.

But Li Ke's "uncle" almost made the eldest grandson Wuji break the defense! Thankfully, he held back.

Even Li Shimin, who was at the forefront, was almost stumbled by Li Ke's "uncle" words, for so many years, has Li Ke called Uncle Wuji, the eldest grandson? It doesn't seem to be.

In private, Li Ke will not visit each other, and he doesn't need to call it in public, it is all called an official position.

As a result, at this time, he came with a sentence of "uncle".

"Snort" "Snort" Many ministers around him were really uncomfortable, but they were also forcibly held back, and they didn't dare to laugh out loud.

Only Cheng Biting Jin and Yu Chi Dasha were smiling, like a shoehorn.

Looking at the back of them leaving, Li Ke smiled faintly, hiding his merit and fame, this is just the beginning.

The renovation of Chang'an City is actually very necessary, Chang'an City is called Daxing in Sui, this is not actually Han Chang'an City, but a new city, a brand new city completed in nine months, with an area of 84.1 square kilometers! This construction speed alone was absolutely second to none in ancient times.

Of course, this is also the reason why the planning, design, manpower, and material resources of the entire project are all big in the early stage of the project, but even so, this speed is really quite perverted in ancient times, so the ancients were really awesome people in all aspects.

And now Chang'an City and Daxing City are also very different, when Daxing City was first built, the roads of the whole city are dirt roads, and then gradually began to lay bricks and stones, slates. And now Li Ke is replacing it with cement roads throughout the city.

In fact, some of the markets in Chang'an City from the Vermilion Bird Gate to the south of the Sixth Heng Street are not inhabited by many people now, and those markets have gradually filled up in the three hundred years of history of the Tang Dynasty, at least the first three dynasties of the Tang Dynasty were definitely not filled, but with the influence of Li Ke, this may change a lot.

I don't live in the city because I don't have a place to live, but with high monthly money, this is really not possible.

Li Ke continued to renovate here, while the eldest grandson Wuji, who had descended from the dynasty, changed his direction with a gloomy face, and after avoiding most of the people, he secretly went to the East Palace.

In the study, when he saw the eldest grandson Wuji, Li Chengqian first saluted the eldest grandson Wuji, and after the two of them saluted each other, the eldest grandson Wuji directly expressed his intentions, and he had nothing to hide between him and Li Chengqian.

"Cheng Qian, don't you have a sense of crisis?" The eldest grandson Wuji asked in a deep voice.

"What does Uncle mean?" Li Chengqian was a little curious.

"Li Ke." The eldest grandson Wuji spat out a name out of his mouth.

Li Chengqian's body paused, he frowned, Li Chengqian actually has a great sense of crisis now, but it is all from Li Tai, because Li Shimin is indeed very conniving with Li Tai, of course, he also knows Li Ke's recent performance, the problem is that Li Ke's background restricts him from sitting in this position.

"You think it's impossible?" Eldest Sun Wuji asked with a sneer.

"I'm afraid there aren't many people in the court who support him, right?" Li Chengqian did not answer directly, but said from the side: "And he has offended almost all the gate valve families in the world, which means that not only the court ministers, but also all the low-level officials in the world are not willing to stand with him." ”

Li Chengqian is not stupid, what Li Ke is doing now seems to be very sensational and grandiose, but in fact it does not affect his status, it is very simple, no one in the court supports him, and Li Ke is desperately offending the gate valve family like death.

What Li Ke said, of course Li Chengqian knew that as a prince, Li Chengqian could not see the harm of the gate valve family, but what was wrong was that if he wanted to stabilize his current position, he still needed the support of these gate valve families.

This has formed a very strange theory, after he ascends to the throne, will he want to learn from Han Gaozu? I'm afraid it's difficult, each era is different from each era.

The emperor wants to deal with the gate valve family, but as the next emperor, the upper position has to rely on the gate valve family, which feels like an unsolvable theory.

And what Li Ke is doing now, it is impossible for him to sit in the position of the emperor, so why should Li Chengqian worry? What's more, Li Ke still has a background problem, with the relationship between his father and the queen mother, the prince can only appear among the sons of the queen mother.

Eldest Sun Wuji paused, he didn't actually know this truth, but he had to instill this idea in Li Chengqian first.

"But you know what? His Majesty is ready to change his title to King of Qin. Eldest Sun Wuji threw out an explosive news.

Hearing the news, Li Chengqian was really stunned.
