Li Shimin, who was deep in thought, suddenly heard Li Min's words, his eyes narrowed slightly, he turned and stared directly at Li Min and said: "Min'er, I won't pursue the previous matter, but what we are talking about now is a major military matter, and you are not allowed to participate without authorization.

Yes, please retreat quickly!"

Li Shimin waved his hand when he said this. Although the altitude sickness that Li Min just explained helped him, in Li Shimin's view, it was just a coincidence. He did not change his view of Li Min from the bottom of his heart, so he did not believe that Li Min could do it.

Is there any good way to build roads?

Li Ke also quietly tugged on Li Min's clothes behind his back, signaling Li Min to stop talking. After all, as princes, they would be very disadvantageous if they were caught making irresponsible remarks about government affairs. Li Min stood just now

When he got up to explain altitude sickness, he was startled. Unexpectedly, Li Min jumped out again this time.

"Father, what I want to say is not a major military or national matter. After all, I don't understand these things, but I know that there is one thing. If you use it to build roads, it will not only be convenient, fast, low-cost, but also durable.

If the rock is not afraid of water and fire, even if the road is flooded by floods, as long as the water is not too deep, you can still walk without any problems." Li Min bowed and saluted again.

"Oh? There is such a thing in this world?" Li Shimin was also aroused by Li Min's words. Fang Xuanling and others below also looked at Li Min with interest. They were now full of curiosity about Li Min.

I don’t understand what amazing move this unexpected King of Liang is going to do?

"Father, this thing is called cement. It is made of several very common materials. It is usually like gray flour. When used, add water, sand, and gravel, mix it, and then spread it on the road. After a few days,

It will turn into a slate-like cement pavement, with a hardness almost the same as real stone. Even if it is soaked in water for several years, it will be fine." Li Min was very satisfied with everyone's reaction, and explained the new invention of cement one by one.

Speak out.

"Okay, Min'er, please make some samples as soon as possible. Then I will check them with all my dear friends!" Li Shimin slammed the table excitedly. Although he had not seen the real thing yet, but just listening to Li Min's introduction, Li Shimin was already sensitive.

Realized the great significance of the emergence of cement.

"My son, I obey!" Li Min immediately stood up and accepted the order. Making cement was really not a difficult task for Li Min. In his previous life, he worked everywhere to make a living. He once stayed in a small unlicensed cement factory for a month. Later, he was really tortured.

I couldn't live in the factory's dusty environment. After a day's work, my hair was covered with cement chunks that couldn't be washed away, so I just paid the money and left after working for a month. Regarding the cement materials and firing process, Li Min was mostly

He still remembered them all, so he was very confident about making cement in Datang.

Fang Xuanling and others were non-committal about the cement. Although they believed that Li Min would not dare to lie about such a big matter, after all, they had not seen the real thing yet and did not know the performance of the cement, so they all remained silent.

Next, Li Min asked Li Shimin to ask some craftsmen to assist him, but he did not expect that Li Shimin directly appointed Li Min as the cement supervisor with a stroke of his pen. He temporarily managed the general supervisor and had the right to use all the manpower and material resources of the general supervisor.

The name "Supervisor" sounds nice, but in fact it is just a temporary official position. It is not registered at all in the Ministry of History, which is in charge of official promotions, and there is no grade. He will be dismissed automatically after the cement is built.

Li Min accepted the order happily, and then Li Shimin drove him and Li Ke out of the hall, and ordered him to take up the post of supervisor immediately and try to make cement as soon as possible.

As soon as he walked out of the hall, Li Ke grabbed Li Min and asked anxiously: "Sixth brother, are you really sure you can make cement? It doesn't matter that we usually mess around, but in these military and national affairs, we must be careful.

You can’t act recklessly!”

"Haha, don't worry, Third Brother, isn't it just a small piece of cement? Didn't I make new tea and distilled liquor before?" Li Min said with a smile on his face, "Other brothers can't guarantee it, but let's talk about it.

When it comes to making these novel items, I dare say that no one in the entire Tang Dynasty can be better than me."

When it comes to inventions, Li Min is absolutely confident. He comes from a later generation and has more than a thousand years of experience than the people of the Tang Dynasty. Coupled with the experience and technology accumulated by working everywhere in later generations, inventing something new is not enough.

Got it within reach?

"This..." Li Ke was still a little hesitant. After all, this was no small matter. If Li Min couldn't do it and was caught by someone who wanted to do it, it would be very detrimental to Li Min.

"Third brother, why don't you just keep following me and help me point out what I'm doing wrong?" Li Min saw that Li Ke still didn't believe it and could only say helplessly.

"That's good. I have an acquaintance at the prison, and I can introduce him to you." Li Ke's eyes suddenly lit up, he thought of a person, and he said very happily. Li Min was sweating profusely. Unexpectedly,

Li Ke really has a wide range of communication and can meet people everywhere.

It's just past noon, and the days are long in June, so it's still early. Li Ke and Li Min rushed to Jiang Zuo Jian together. Jiang Zuo Jian is located in the imperial city. After exiting Taiji Palace and passing through Chengtian Gate, turn right, next to

Next to the palace wall is the general supervisor. The general supervisor is in charge of civil construction matters. There are two master craftsmen, from the third rank, and two young eunuchs, from the fourth rank. There are also left school and right school in the prison.

Lieutenant Colonel, Zhen Guan and other departments, there are two people in the department, and one person is the chief.

When they arrived at the general prison, they saw that the general prisoner was already waiting for them. They probably had received Li Shimin's order, but they spared Li Min the time to explain.

"The great craftsman Yu Wenhu, the general supervisor, has met His Royal Highness the King of Shu and His Royal Highness the King of Liang!" The young black-faced official who led the group saluted.

"Haha~, brother Yuwen, let's stop playing with these false gifts between you and me!" Li Min was about to return the gift, but he didn't expect that Li Ke went up and punched Yuwen Hu, smiling in an intimate manner.

Li Min suddenly realized that the acquaintance of Li Ke was actually the master craftsman who would be the supervisor. No wonder Li Ke had to introduce him to him. With the help of Brother Yuwen, he could indeed feel much more relaxed.

"Liu Lang, come here, let me introduce you. This is my good brother Yu Wenhu. His grandfather is the former construction master Yu Wenkai. Brother Yuwen has a long history of family studies. He is very accomplished in construction and has won the respect of Yu Wen.

The true biography of the senior." Li Ke waved over Li Min, patted Yu Wenhu's shoulder and introduced him.

Yu Wenkai, as mentioned by Li Ke, is an outstanding man. He was born into a family of military generals and heroes. He has read extensively since he was a child. He is proficient in the laws and regulations of the past dynasties and various craft skills. He personally designed the construction of many large cities, such as Chang'an and Luoyang.

The famous big cities were all designed by him, and he also participated in the design of the Beijing-Hangzhou Grand Canal. It can be said that Yu Wenkai was involved in almost all large-scale projects during the period of Emperor Yang of the Sui Dynasty.

"Haha, I have heard the name of Brother Yuwen mentioned by the third brother a long time ago. Unfortunately, we have never had a chance to meet each other. I didn't expect that we would meet for official business today. I will definitely have a drunken time with Brother Yuwen another day." Li Min also hurriedly came up to try to make friends. Anyway, Li Min

Ke will not expose him.

"His Royal Highness King Liang is so polite. I have been admiring His Highness for a long time. Who in the entire Chang'an city doesn't know Li Liuyang's name?" Yuwen Hu was also very polite. Although he and Li Ke had some friendship, they didn't know each other in person.

When meeting Li Min for the first time, he still didn't dare to be too presumptuous.

Li Min liked others to praise him most, and he had a good impression of Yu Wenhu at the moment. The two complimented each other a few more words, and then turned to the topic.

"Brother Yuwen, this time my father sent me to bake cement. Everything else will be easy to handle, but the personnel selected must be able to keep confidentiality. I am not familiar with generals as supervisors, so I have to take care of Brother Yuwen.

"Li Min didn't want someone to leak it out as soon as he figured out how to bake cement. He was still counting on making money from this.

"Don't worry, Your Highness, I will personally select trustworthy people!" Yu Wenhu assured, patting his chest, but soon frowned and asked, "But we have never seen such a thing as cement, so I didn't know that Your Highness needs it.

What kind of manpower and materials can a lower official prepare?"

Li Min thought for a moment and then said: "Hmm~, I wonder if the general supervisor has craftsmen who can bake lime or ceramics? The firing of cement is actually very simple. Anyone who can bake lime or ceramics should be able to do it.

"

"Haha, there are many of these two types of craftsmen's prisons. They belong to the Right School Office and Zhen Guan Office, which are the supervisors. The subordinates will be able to find them right away." Yuwen Hu breathed a sigh of relief after hearing this. He was originally worried about Li

I’m shocked that it’s so hard to find craftsmen with the required requirements. I didn’t expect the requirements for cement firing to be so low?

"Okay, please also ask Brother Yuwen to prepare some limestone, clay, iron slag and gypsum. These are all materials for firing cement." Li Min then ordered again.

"Don't worry, Your Highness, I will go and make preparations now. Please come to the hall and wait for a moment!" Yu Wenhu is worthy of his background in technology. He is a typical activist. After listening to Li Min's instructions, he immediately left and sent Li Min.

Min and Li Ke stayed in the hall of his official office.

"Haha, this brother Yuwen is still the same as before. He does everything in a hurry and never loses a moment." Li Ke knew Yuwenhu's character for a long time and said to Li Min with a smile.

"Brother Yuwen is a practical person, and only a person like him can be qualified for the position of master craftsman." Li Min admired Yuwenhu very much. There were more types of craftsmen in the prison than in his house.

There are many. If he wants to do something new in the future, he will probably have to deal with Yu Wenhu.

The two sat in the hall for a while, feeling a little bored. Li Ke had a restless temper, so he stood up and walked around the hall a few times, then walked to the corner of the hall skillfully, opened a hidden door and opened a small hidden door to Li Min.

He beckoned: "Sixth brother, come and see the novelties produced by the director, there are a lot of good things in them!"
Chapter completed!
