Li Shimin, who was pondering, suddenly heard Li Su's words, his eyes were slightly condensed, and he turned to stare directly at Li Su and said: "Su'er, I won't pursue the previous matter, but now we are talking about military affairs, and it is not something you can participate in without permission, so don't step back quickly!" ”

Li Shimin waved his hand when he said this, although the altitude sickness that Li Su just explained helped him, but in Li Shimin's opinion, this was just a coincidence, and he did not change his opinion of Li Su from the bottom of his heart, so he didn't believe that Li Su could have any good way to build roads.

Li Ke also quietly pulled his clothes behind Li Su's back, signaling Li Su not to speak again, after all, as princes, they were vainly discussing the government if they were caught by someone with a heart, but it was very unfavorable to themselves.

"Father, what the son wants to say is not a military matter, after all, these things are not understood by the minister, but the son knows that there is one thing, if you use it to build a road, it is not only convenient and fast, low cost, but also rock solid and not afraid of water and fire, even if the road is flooded, as long as the water is not too deep, you can still walk unharmed." Li Su bowed down again and saluted.

"Oh? Is there such a thing in this world? Li Shimin was also intrigued by Li Su's words. Fang Xuanling and the others below also looked at Li Su with interest, they were now full of curiosity about Li Su, and they didn't understand what this unexpected King Liang was going to do?

"Father, this thing is called cement, it is made of several very common materials, usually like gray flour, when you use it, add water, sand, and gravel to stir, and then pave it on the road, and after a few days, it will become a cement pavement like a stone slab, and the hardness is almost the same as that of a real stone, even if it is soaked in water for several years, it is fine." Li Su was very satisfied with everyone's reaction, and told the new invention of cement in 1510.

"Okay, you can make some samples as soon as possible Chapter 33 Fired Cement (I), and I will check it with all Aiqing at that time!" Li Shimin slapped the table excitedly, although he had not seen the real thing, but only listened to Li Su's introduction, Li Shimin was already sensitively aware of the great significance of the appearance of cement.

"The retainers obey!" Li Su immediately got up and received the order. In his previous life, he worked everywhere for his life, and once spent a month in a small unlicensed cement factory, and then he couldn't stand the dusty environment in the factory, and his hair was full of cement blocks after a day's work, and he couldn't wash it off, so he paid for it and left directly after a month, and most of the materials and firing process of cement were remembered, so he was still very confident in making cement in Datang.

Fang Xuanling and the others were noncommittal about cement, although they believed that Li Su would not dare to lie about such a big thing, but after all, they had not seen the real thing, and they didn't know what the performance of cement was, so they all kept silent.

Next, Li Su proposed to Li Shimin that he wanted some craftsmen to assist him, but he didn't expect Li Shimin to wave his pen and directly appoint Li Su as the cement superintendent, temporarily manage the superintendent, and have the right to call all the manpower and material resources of the superintendent. The name of the superintendent is good, but in fact it is only a temporary official position, and there is no record at all in the history department in charge of the promotion of officials, and there is no grade, and it will be automatically dismissed after the cement is made.

Li Su gladly accepted the order, and then Li Shimin drove him and Li Ke out of the main hall, and instructed him to immediately go to the post of supervisor and try to make cement as soon as possible.

As soon as he walked out of the main hall, Li Ke grabbed Li Su and asked anxiously, "Sixth brother, are you really sure to make cement?" It doesn't matter if we usually mess around, but in these military affairs, we must not mess around! ”

"Hehe, third brother, don't worry, isn't it just a small cement, don't you see that I made new tea and distilled liquor before?" Li Su said with a smile on his face, "Other junior brothers don't dare to guarantee it, but when it comes to making these novelty items, I dare to say that in the entire Tang Dynasty, absolutely no one can be better than me." ”

For the invention of this aspect, Li Su is absolutely full of confidence, he is from the later generations, more than a thousand years of knowledge than the Tang Dynasty, coupled with the experience and technology accumulated by working around in later generations, inventing something new is not handy?

"This ......" Li Ke still hesitated, after all, this is not a trivial matter, in case Li Su can't do it, if he is caught by someone with a heart and doesn't let go, it will be very unfavorable to Li Su.

"Third brother, otherwise you will follow me all the time, see what the younger brother is doing wrong, and help me point me out?" Li Su saw that Li Ke still didn't believe it, so he could only say helplessly.

"That's fine, I have an acquaintance in the prison who can help you introduce him." Li Ke's eyes suddenly lit up, he remembered someone, and said very happily at the moment. Li Ke was sweating profusely, but he didn't expect Li Ke to really communicate broadly, and there were people he knew anywhere.

It was just after noon, and the days were long in June, so it was still early, so Li Ke and Li Su rushed to the prison together. The prison will be located in the imperial city, out of the Taiji Palace through the Chengtian Gate turn right, next to the palace wall is the will be the prison. will be in charge of the construction of civil engineering, with two master craftsmen, from the three products; There are two young prisoners, and from the fourth grade, there are also left schools, right schools, middle colonels, Zhen officials and other offices in the prison, and there are two officers and one person in the department.

When they came to the prison, they saw that the person who was going to be the prisoner was already waiting for them, and it was estimated that they had already received Li Shimin's will, but they saved Li Su from explaining.

"I will be the master craftsman Yu Wenhu, and I have seen His Royal Highness the King of Shu and His Royal Highness the King of Liang!" The young black-faced official at the head saluted with a human salute.

"Haha~, Brother Yuwen, don't play these false courtesies between you and me!" Li Ke was about to return the gift, but he didn't expect Li Ke to go up and punch Yuwen Hu, and said with an intimate smile.

Li Su suddenly realized that the acquaintance Li Ke knew turned out to be a master craftsman who would be a prisoner, no wonder Li Ke had to introduce himself, with the help of this Yuwen brother, he could indeed be much easier.

"Liuyun come on, let me introduce you to you, this is my good brother Yuwen Hu, his grandfather is the former dynasty builder Yu Wenkai, Yuwen brother has a family history, and he has a deep knowledge in construction, and he has won the true inheritance of Yuwen's predecessors." Li Ke beckoned over Li Su and patted Yuwen Hu's shoulder to introduce him.

Li Ke's Yuwenkai is a bull, he was born in a family of military generals, well-read since childhood, proficient in the rules and regulations of the past dynasties and a variety of craft skills, personally designed the construction of many big cities, such as Chang'an, Luoyang, the two world-famous big cities, are from his hands, but also participated in the design of the Beijing-Hangzhou Grand Canal, it can be said that in the large-scale projects of the Sui Yang Emperor period, almost all of them have Yu Wenkai's figure in it.

"Hehe, I've heard the third brother mention Brother Yuwen's name for a long time, but unfortunately I haven't had the chance to meet, I didn't expect to meet today because of business, and I must get drunk with Brother Yuwen another day." Li Ke also hurriedly came up to set up a friendship, anyway, Li Ke would not expose him.

"His Royal Highness King Liang is polite, the lower officials have really admired His Royal Highness for a long time, and now in the entire Chang'an City, who doesn't know Li Liuyang's name?" Yuwen Hu is also very polite, although he has some friendship with Li Ke, but when facing Li Ke who met for the first time, he still didn't dare to be too presumptuous.

Li Su likes others to praise him the most, and his current impression of Yuwen Hu is very good. The two praised each other a few more words, and then turned to the topic.

"Brother Yuwen, this time my father sent me to burn cement, and other things are easy to do, but the selected manpower must be able to be kept secret, and the younger brother is not familiar with the general prisoner, so there must be Brother Lao Yuwen for this." Li Su didn't want to let people leak it out as soon as he figured out the firing method of cement, and he was still counting on this to make money.

"Your Highness, rest assured, the lower officials will personally select the people who have passed the letter!" Yuwen Hu patted his chest and promised, but soon frowned and asked, "But we haven't seen anything like cement, I don't know what kind of manpower and materials His Highness needs, so it's better for the lower officials to prepare?" ”

Li Su thought for a moment, and then said: "Hmm~, I don't know if there will be craftsmen who burn lime or ceramics in prison?" The firing of cement is actually very simple, and anyone who can burn lime or ceramics should be able to do so. ”

"Hehe, there are many of these two kinds of craftsmen in the prison, which belong to the Right School Office and the Zhen Official Office who will be the supervisor, and the lower officials will be able to find people immediately." Yuwen Hu breathed a sigh of relief after hearing this, he was originally worried that the craftsmen asked by Li Su were too difficult to find, but he didn't expect the firing of cement to be so low?

"Okay, in addition, I also ask Brother Yuwen to prepare some limestone, clay, iron slag and gypsum, which are all materials for firing cement." Li Su then commanded again.

"Your Highness, rest assured, the lower officials will go to prepare, please wait in the hall for a while!" Yuwen Hu is worthy of being a technical background, a typical man of action, and immediately left after listening to Li Su's orders, leaving Li Su and Li Ke in the hall of his official office.

"Hehe, this Brother Yuwen is still the same, he does everything in a hurry, and he doesn't delay for a moment." Li Ke had long understood Yuwen Hu's character, and said to Li Su with a smile.

"Brother Yuwen is a person who does practical things, and only a person like him can be qualified for the position of a master craftsman." Li Su admires Yuwen Hu very much, there are many more types of craftsmen in the prison than in his house, and if he wants to do anything new in the future, it is estimated that he will have to deal with Yuwen Hu.

The two sat in the hall for a while, feeling a little bored, Li Ke was an idle character, stood up and walked around the hall a few times, and then walked to the corner of the hall very skillfully, opened a hidden small door and beckoned to Li Su: "Sixth brother, come and take a look at the novelty that will be produced by the supervisor, there are a lot of good things in it!" ”！！！
