Li Wei thought that he would return in one day, but he didn't think that he was directly left in Beijing.

Although the construction of the city was to complete the official duties of the Ministry of Industry, it was also what he wanted to do, in addition to making money, it could also bring many other benefits, such as cultivating the skills of craftsmen, stimulating various industries, manufacturing some new machinery, and so on.

Zhu Yuanzhang's move seriously hit his enthusiasm, and after a few days of recuperation, he couldn't help but ask to play twice, but both were rejected.

Helpless, he could only follow Zhu Yuanzhang's wishes and let Jiang Shouqing preside over the construction of the city for him.

At the Yamen of the Ministry of Industry, Li Wei was a little irritable and explained to Jiang Shouqing the use of cement.

"This cement, as long as it is mixed with sand and gravel in a certain proportion, can replace glutinous rice gray water as a binder for building a city, and it can also be directly used as a construction material, and the hardness after solidification is comparable to stone." Li Wei pointed to a bag of cement that he had ordered someone to get and said.

Jiang Shouqing usually doesn't communicate much with him, but he is really careful in his work, and he almost never worries about the affairs of the Tuntian Qing Officials.

And Jiang Shouqing is indeed a pragmatic person, he was surprised to hear his descriptions, and asked endless questions:

"Why is that?"

He can understand that cement can be coagulated as a binder, and clay is like that, but after solidification, the hardness is comparable to that of stone, which he can't understand.

Li Wei frowned slightly and explained: "Well, it's a kind of hydration reaction, these powder particles will slowly expand and become larger after encountering water, the density will increase, and the natural hardness will also increase, understand?" ”

Jiang Shouqing frowned and pondered, trying to imagine the picture described by Li Wei, but he still couldn't understand it.

"Why don't you understand? After the particles expand, they squeeze each other, and the gap in the middle is smaller, which is naturally more solid......"

Li Wei was a little impatient.

After listening to this, Jiang Shouqing seemed to understand a little, but he didn't understand it too much.

Li Wei frowned, and said a little impatiently: "Forget it, you just need to know that after this thing solidifies, you have to pour water to maintain humidity, so that it can be tighter." ”

Jiang Shouqing was even more surprised: "Since it has been solidified, why do you still need to drench it?" ”

Li Wei glanced at him, feeling a little helpless.

The use of cement is not so simple, in addition to the mixing ratio of sand and gravel, it is also necessary to be cured with water after solidification to ensure that it fully completes the hydration reaction in order to ensure hardness and strength.

And depending on the intensity of sunlight, the time of drenching is different.

If he can go to the scene by himself, he can naturally direct the craftsmen to do it at a good time, and when these craftsmen are familiar with the process, there will naturally be no problem after that, and now it is because it is the first time to use it, he has to teach it by hand.

Looking at Jiang Shouqing's half-understood appearance, he was even more uneasy, if this was not done well, it would be a big trouble.

Hey?

Li Wei was about to patiently explain to him carefully, but suddenly his heart moved.

If you don't understand, just let him tell Zhu Yuanzhang if he doesn't understand, if Jiang Shouqing can't do it, then Zhu Yuanzhang has to let him go in person?

Thinking of this, Li Wei suddenly changed his words, and said to him seriously: "Shouqing, knowing is knowing, not knowing is not knowing, you have a very good attitude, so let's do it, you can just play Your Majesty and say that you don't understand." ”

"Huh?"

Jiang Shouqing was stunned, a little stunned in his heart.

He actually understood a little, as long as Li Wei explained it carefully, he felt that it should be fine.

But Li Wei stopped explaining directly, and patted him on the shoulder with a smile, "Tell Your Majesty as soon as possible, don't delay the progress of building the city." ”

"This ...... All right. Jiang Shouqing replied reluctantly, he still wanted to hear Li Wei explain clearly.

Li Wei ignored his eager eyes, directly asked people to put away the cement, and the originally planned demonstration was canceled, and he waved his hand and drove him out.

After Jiang Shouqing left, Ru Taisu followed closely to see Li Wei.

Li Wei went to him several times without notification, and he would not be polite, so he broke in directly.

"Master Li, tell me about your purchase of land, Your Majesty has asked me to be in charge of this matter, and I still have some questions to communicate with you!"

Ru Taisu came to Li Wei with a happy face and said.

Zhu Yuanzhang ordered him to be in charge of Li Wei's plan to buy land, and he immediately realized that this was a great thing for the benefit of the country and the people, and he was greatly surprised.

However, in the face of his inquiry, Li Wei took a sip of tea unhurriedly, and then said leisurely: "Lord Ru, buy the land, it can only be understood, not spoken, understand is understand, if you don't understand, it's useless to say it." ”

When Ru Taisu heard his mysterious words, the joy on his face suddenly froze, and he said with some displeasure: "Why can't you say it?" Isn't it just to give benefits to the households and increase their enthusiasm for reclaiming wasteland? You think I don't understand anything, do you? ”

"Yo, yes, Lord Ru is very perceptive!" Li Wei praised in surprise.

Ru Taisu glanced at him disdainfully, a little proud in her heart.

"Since this is the case, then there is no need for the official to say more, if Mrs. Ru has any doubts and can't do it, she will directly write to Your Majesty and ask Gao Ming."

Li Wei followed the temptation, hoping that he could play directly like Jiang Shouqing, so that he could go out in person.

However, Ru Taisu didn't give him this face, and when he heard his words, he snorted a little angrily: "Hmph, if you don't say it, you won't say it, you can't figure it out without your old man." ”

After speaking, Ru Taisu waved his sleeves and left.

Li Wei's face froze, and he couldn't sit still, so he quickly got up and chased after him: "Don't, Lord Ru, just tell Your Majesty that you can't do it, and let me ...... the rest."

Ru Taisu ignored it and left the Ministry of Industry without looking back.

Although Ru Taisu did not cooperate, Jiang Shouqing was still obedient and handed over the book early, and although Ru Taisu had some views on the matter of buying land and hoarding land, he did not understand what kind of investment banknotes were issued, and finally had to ask for instructions.

Soon, these recitals were handed to Zhu Yuanzhang's imperial case, and Zhu Yuanzhang couldn't help frowning when he looked at the two of them who "couldn't do it".

"This stinky boy, dare to play this trick with us!" Zhu Yuanzhang scolded in a low voice.

As far as Li Wei's careful thinking is concerned, he can see through it at a glance.

After a moment of silence, he raised his head and instructed Xu Shou on the side: "Go, let someone call that stinky boy to us!" ”

"Yes!" Xu Shou bowed down, walked away quickly, went outside and gave a few orders, and soon a little eunuch went out of the palace to find Li Wei.

Soon after, Li Wei was brought into the palace and came to Zhu Yuanzhang.

Zhu Yuanzhang threw the book in front of him and glared at him angrily: "You just want to go by yourself like this?" ”

Li Wei quietly glanced at the book on the ground, and knew that his own method had worked without looking at it, and he suddenly felt a little secretly happy in his heart.

"Your Majesty, after all, Yangzhou Xinjian is the first time to try this method, the minister does not personally go to star, it is really a little uneasy, in case things are messed up, you blame it, the minister can not afford to bear it!"

Li Wei said softly.

"Hmph, it's for your own good that we won't let you go!" Zhu Yuanzhang said unhappily.

"The minister understands, thank Your Majesty for your grace, but the minister can't be in danger once and won't go out in the future, right? In that case, how can you contribute to the Ming Dynasty? ”

Li Wei said softly.

In fact, the reason why he wanted to go out in person was that in addition to completing the task and driving the development, deep down he also wanted to take this as a starting point and gradually move away from Jingshi, so as to prepare for leaving Daming and flying high in the future.

Although he saved Queen Ma, was like Anqing again, and his relationship with the old Zhu family was further, he still had no change of ambition, thinking of taking Xiaoqing and Anqing overseas to find a place to be at ease, away from these rules and grievances of the Ming Dynasty.

According to history, ah no, it was staged on TV, and the current Ming Dynasty is quite calm, but when Zhu Yuanzhang gets old, it will be bloody, and later Jianwen will rebel, he doesn't want to fall into this whirlpool.

Zhu Yuanzhang didn't think much about this, but he was active and hard-working with a work attitude, and he was both satisfied and hesitant for a while.

After pondering for a moment, Zhu Yuanzhang finally made a decision in his heart, and said in a deep voice: "Do you know why we let you go to Yangzhou?" ”

Li Wei was stunned, not understanding what he meant by suddenly asking.

Zhu Yuanzhang didn't wait for him to answer, so he got up and went to the apse, and after a while, he took a long brocade box and handed it to Li Wei.

"Open it and take a look." Zhu Yuanzhang said lightly.

Li Wei took it suspiciously, opened it and looked at it, only to see that there was a holy decree in the box, but unlike ordinary holy decrees, this scrolled holy decree was woven from precious silk brocade and made of jade, which was very gorgeous. (End of chapter)
