After Li Shimin inspected for a while, he took Yu Wenshi and left the present.

When Li Chengqian wanted to leave.

And Duan Lun stopped Li Chengqian

"His Royal Highness the Prince, please stay!"

Li Chengqian stopped.

"Oh? What is Duan Shangshu? ”

Duan Lun said: "Thank you, Your Royal Highness the Crown Prince, what do you need, just talk about it." ”

Not to mention, Li Chengqian really needs Duan Lun to do something.

Next they were working on cement.

And what is cement? That is the powdered hydraulic inorganic cementitious material. After adding water and stirring, it forms a slurry, which can be hardened in air or water, and can firmly cement sand, stone and other materials together.

The mixture of early lime and pozzolana was similar to that of modern lime pozzolana cement, and the concrete made from cemented crushed stone was not only strong when hardened, but also resistant to the erosion of fresh or salt water.

According to this characteristic, Li Chengqian knew what to do.

"This king wants you to get some lime and volcanic ash, can you do it?"

When Duan Lun heard this, he asked:

"Lime is easy to do, but what is volcanic ash?"

"Yes, it's the ash from the eruption!"

After Li Chengqian said this, Duan Lun seemed to think of something.

"This seems to be found near the Flaming Mountain!"

It is best to get nature, so Li Chengqian said:

"Okay, within two days, you must get 3,000 catties, is it difficult?"

Three thousand catties is not much.

When Duan Lun heard this, he said with a package ticket: "There is no difficulty!" Your Royal Highness the Crown Prince, please rest assured, the minister will definitely complete it! ”

"Well, in two days, this king is waiting for you here! If not, remember to say it in advance, don't say it until the end! ”

"Yes!"

Of course, the steel is also very advanced now, and Li Chengqian, of course, also wants to build reinforced concrete to ensure the degree of solidity.

I believe that Li Shimin will be shocked in the future, and collect a wave of points by the way.

As soon as Li Chengqian finished speaking, he left.

Duan Lun went down to prepare one or two.

And in the next two days, there were people gossiping about Li Shimin.

In particular, Yu Wenshi and Li Shimin's ears constantly slandered Li Chengqian's behavior.

"Your Majesty, His Royal Highness the Crown Prince has not acted in the past two days, I am afraid that he did not take the words of that day to heart, he knows that His Majesty is very concerned about the city defense, but he is not concerned at all, and is busy with other things, according to the minister's opinion, do you want to urge it?"

Li Shimin was puzzled and asked, "Gao Ming really didn't do anything?" ”

Yu Wenshi took the opportunity to say: "Yes, Your Majesty, His Royal Highness the Crown Prince at this time travels with Wu Yu every day, and he does not take state affairs to heart at all, and please make a decision on your Majesty!" ”

"Yu Wenshi and, Gao Ming has grown up, this relationship between men and women should also be released, from last year to now, as the crown prince, he has done better than any dynasty, he should not be blamed at this time, he is still a nine-year-old child!"

Of course, Empress Changsun is speaking for Li Chengqian.

Li Shimin also didn't care.

"Sometimes I'm too strict with him, so it's hard to have a few days off, so let him go!"

"But Your Majesty, the matter of the city wall cannot be delayed! One more day, one more day dangerous. If you get it done early, you can also keep the people safe! ”

Yu Wenshi and very urgent request.

If you talk too much about a thing, you will involuntarily pay attention to it.

Hearing what Yu Wenshi said, Li Shimin seemed to think that this was the case.

Yu Wenshi took a step further and said: "Now is not the time to fall in love, His Royal Highness the Crown Prince shoulders a heavy responsibility, and he must deal with national affairs with the warmest mood at all times!" ”

"Yu Wenshiji, you're too demanding, aren't you? He's still a kid! ”

Empress Eldest Sun was the first to be unhappy and said directly

"Her Royal Highness the Queen, the minister is also thinking about the Tang Dynasty! And His Royal Highness the Crown Prince is now a scholar, and naturally he also has to shoulder the heavy responsibility of developing the Tang Dynasty, the greater the so-called ability, the greater the responsibility! The minister is not wrong, right? ”

Yu Wenshi and they are all about to cry, whether it is true or not, whether it is true or not, it is moving.

"Yu Wenshi and what he said is not unreasonable, Gao Ming has really not been moved in the past two days?"

Li Shimin asked.

"Yes, Your Majesty, the minister has been looking at the city wall for the past two days, and there is no special change, it is still the same."

"No, it doesn't make sense, Gao Ming won't be like this!"

Li Shimin didn't want to believe that Li Chengqian would not do anything.

"Maybe it's because of what he's doing, we don't know!"

"Her Royal Highness the Queen, the minister also asked people to inquire, His Royal Highness the Crown Prince has not done anything, and is now accompanying the daughter of the martial family in the East Palace, the minister thinks that His Royal Highness the Crown Prince has lost a big one because of a small loss, and this daughter of the martial family is probably not a good person!"

Yu Wenshi and even burned the war on Wu Jue, also because Liu Hui was not elected as the crown princess, right? He was on Liu Hongji's side.

"Oh? Is this really the case? ”

"Therefore, the minister thinks that it is a plan to let Liu Hui, the daughter of the Duke of Kui, be elected as the crown princess!"

Yu Wenshi and sure enough, he still said so

"Your Majesty's will has been decided, how can it be changed at will? Yu Wenshi, you're too lenient, aren't you? This crown princess was elected by His Majesty and the ministers, and she can't be abandoned because of a trivial matter? If it is a new election, this palace thinks that it can be elected from the people, no matter how it turns, it will not be Liu Hui's turn! ”

Empress Eldest Sun is a little disgusted with Yuwenshi, after all, the position of the crown princess is something that everyone wants.

But it's just that Yu Wenshi's eating appearance is too ugly.

How could she do what he wanted?

And her relationship with Wu Zetian has become better and better.

For this prospective daughter-in-law, she is very concerned.

"Your Royal Highness, the minister is just a suggestion. It is not the intention of swaying His Majesty. ”

This frightened Yu Wenshi and a little trembling, he definitely didn't know that at this time, the relationship between Wu Zetian and Empress Changsun had become very good.

"This palace has another thing to say, the matter of the crown princess is so decided. And the real situation there can't be concluded by your family's words! There is still one day left before the three-day appointment, and we only need to wait for tomorrow to know. Don't chew on the root of our ears next to us, it's annoying, you know? ”

Empress Eldest Sun's sudden strength made Yu Wenshi a little overwhelmed.

At the same time, Li Shimin also regained his senses.

"I think the queen is right, let's see the situation tomorrow."

"Your Majesty......"

"Okay, don't talk about it, what about letting him play for a few days? I can't finish it tomorrow, so I'll give it another three days. ”

Li Shimin said with a gloomy face. After all, Li Chengqian can't finish it, so what? Give him another three days, so what? Why be harsh on him?

If it weren't for the presence of Empress Changsun, I'm afraid this matter would not be over.

Yu Wenshi had no choice but to touch his nose and said, "Yes! ”
