After the early dynasty, Duan Lun, the secretary of the Ministry of Industry, found him, and Li Su, the cement superintendent, temporarily belonged to the Ministry of Industry, and was nominally under Duan Lun's management. The identity of this Duan Shangshu is not simple, Li Su has to call him uncle, his wife is Li Shimin's fourth sister Princess Gaomi, Li Su also saw it at the last banquet, but that Princess Gaomi is very low-key and quiet, not as active as Princess Danyang.

"Liulang sees his uncle, and in the future, the little nephew will eat under his uncle, I hope uncle, you don't embarrass the little nephew!" Li Su didn't have a deep impression of Duan Lun, he only remembered that he drank a lot, don't look at him as a civil official, the last time he fought with those veteran ruffians at the Five Kings Banquet, he was not inferior.

"Haha~, Liulang, you are too modest, you can come to this small temple of the Ministry of Industry, it is really Chapter 41 The Human Cat Li Yifu and the New Workshop have commissioned you!" Duan Lun smiled haha, and by the way, he also praised Li Su a few words, and then said: "Liulang, you go to the Ministry of Industry with me, I helped you select some competent people yesterday, and the office space was also cleaned up, just waiting for you, the superintendent, to take office." "Although the holy decree was only issued today, Duan Lun received a notice from the palace yesterday and had already prepared everything.

"Hehe, then there is Uncle Lao!" Li Su hurriedly thanked. The two went out of the palace and got into the same carriage, and Duan Lun was very enthusiastic about it, and asked Li Su questions, Li Su was also very respectful, and answered one by one, which made Duan Lun have a good impression of him.

After entering the Ministry of Industry, Li Su found that this place was very different from his imagination, in his imagination, the Ministry of Industry should be a comprehensive large workshop, which was full of all kinds of craftsmen, working in their respective workshops. But after coming in, he found that in fact, the Ministry of Industry is a very ordinary government department, and the people working in it are ordinary officials at all levels, and there are no craftsmen at all, which makes Li Su very puzzled.

If you don't understand, you have to ask, and after Li Su told his doubts, Duan Lun laughed, and after a long chapter 41, the human cat Li Yifu and the new workshop would quip: "Liulang, according to your idea, then I, the secretary of the Ministry of Industry, will not become a master craftsman?" But I don't have the skills of craftsmen! ”

This Duan Lun is also funny, seeing Li Su's very depressed expression, he laughed again, but after laughing, he still explained the situation of the Ministry of Industry to Li Su in detail. Of course, the supreme governor of the Ministry of Industry is him, the Shangshu, and there is also a squire, which is his deputy, and there are four departments under the Ministry of Industry, each with a Lang Zhong and a member of the Wai Lang, and each department also has several directors, who are in charge of all aspects of things.

As for the craftsmen mentioned by Li Su, of course there are in the Ministry of Industry, but most of them are in the major workshops under the jurisdiction of the Ministry of Industry, and there are also a few craftsmen who have been promoted to officials because of their exquisite craftsmanship, but these technical officials are not here, but work in a large workshop behind the Ministry of Industry, and their work is also different from that of ordinary officials, mainly to use their exquisite skills to improve the existing technology, which is equivalent to the research and development institutions of later generations. It's a pity that due to secrecy, even the prince Li Su can't easily enter it, which makes him very disappointed.

The operation of cement is very important, Duan Lun also attaches great importance to it, so he specially sent a famous director as Li Su's deputy, and there are more than a dozen experienced officials to assist, as for Li Su's office, it is next to the Ministry of Industry, is an independent yard, the area is not small, nearly 30 acres, there are many houses, not only there is a place for the usual office, and even a room for temporary rest.

Duan Lun took Li Su around the courtyard, and finally came to the hall where the guests were received, and all the personnel transferred from the Ministry of Industry had been waiting in the hall for a long time. The leader was a nine-rank chief in a green robe, and as soon as these people saw Li Su and Duan Lun coming in, they immediately bowed down and saluted: "See His Royal Highness King Liang and Lord Shangshu!" ”

"Well, get up!" After Duan Lun finished speaking, he turned his head and said to Li Su, "Liuyun, let me introduce to you, this is Li Yifu, the director of the Ministry of Industry, don't look at him young, but he is very talented, and he is a rare young man in my Ministry of Industry!" ”

In fact, there is no need for Duan Lun to focus on the introduction, Li Su has already noticed the head of the Ministry of Industry, not only because he is the only official in the crowd, but more importantly, this person is too young, he looks about twenty years old at most, with long lips and red teeth and white teeth is very handsome.

"Weichen Li Yifu, participate in His Highness!" Hearing Duan Lun introduce himself, Li Yifu hurriedly took two steps forward and bowed to the tunnel.

Li Yifu? Li Su always feels that this name is a little familiar, is it possible that he is a historical celebrity again? But now is not the time to think about it, so he smiled and said: "Hehe, I didn't expect that Director Li is so young, and he has been valued by Lord Shangshu, it is really my blessing of the Tang Dynasty!" ”

"His Royal Highness Xie praised, Xia Guan actually has no ability, but he is just serious, and these are all thanks to Lord Shangshu's good teaching, so that the villain has the opportunity to follow His Highness." Although this Li Yifu is young, he speaks without leaking, not only praised Li Su and Duan Lun, but also praised him himself.

"Haha~, Yifu is still so good at talking, and the old man's favorite thing is a young man like you." Duan Lun obviously likes others to pat him on the back the most, and he was so happy that he couldn't find the north all of a sudden, no wonder he handed over such an important matter as cement to Li Yifu?

Li Yifu? Wait a minute! Li Su suddenly remembered, this Li Yi Mansion can't be the Li Yi Mansion in history, right? The one who is known as one of the two major thugs under Wu Zetian, and is the best at stabbing knives in the back with a smile in the face, so he is also known as the 'human cat', and Li Linfu, who is known as the 'Honey Belly Sword', has to be called "senior" when he meets him. If it was really him, then Li Su met an amazing guy today.

"Listening to Director Li's accent, it seems that he is not from Chang'an, and he came to Chang'an to work in Chang'an without knowing why?" Li Su was not sure, so he could only test it first.

"Your Royal Highness, the ancestral home of the lower official is Raoyang County. After moving to Yongtai, Zhenguan came to Chang'an after eight years of recommendation. Li Yifu still looked like a smile, and replied honestly.

Li Yi was shocked, he didn't know where Li Yifu was from, but he knew that Li Yifu did come to Chang'an in the eighth year of Zhenguan, and served as many low-level petty officials at the beginning, until Li Zhi was named the crown prince, Li Yifu climbed the high branch of Li Zhi, and then began to soar. Now that the name and time are right, it seems that he is the person who is known as one of the two major thugs under Wu Zetian in history.

"Liuyang, I still have some things to deal with over there, you can get more familiar with Director Li and them, and then let Director Li take you to see the newly built cement workshop outside the city, all the craftsmen who have been allocated are there." Duan Lun saw that he didn't have anything to do with himself, so he got up and said goodbye, after all, he was not available to accompany Li Su all the time.

"Oh, that little nephew sends my uncle!" Duan Lun's words interrupted Li Su, who was in a daze, and he hurriedly stood up and sent Duan Lun out, and of course Li Yifu and the others followed. Except for Li Yifu, the head of the Nine Grades, the others are all small officials without any grade, and Li Yi doesn't need to know, just tell Li Yifu directly if there is anything.

Although he was shocked by Li Yifu, a historical celebrity, Li Yi didn't think much about it, he still had to use it, and the first thing he did was to order Li Yifu to make a plaque of 'Cement Supervision Institute', and then hang it at the door of the courtyard, which is the official name of his cement supervision officer.

Then Li Su talked to everyone again, and it was noon at this time, so Li Su invited guests, and everyone went to the restaurant opened by Wang Zihao for a big meal. In the afternoon, led by Li Yifu, Li Su went out of the city again to the place set aside by the Ministry of Industry as a cement workshop.

On the way, after the introduction of Li Yifu, Li Su learned that this new workshop was also a lime workshop of the Ministry of Industry, Duan Lun heard that Li Su was using the lime workshop to refine cement in the prison, so in order to facilitate Li Su, this large-scale lime workshop was carved out, which was also considered to provide some convenience for Li Su. This made Li Su sigh with emotion, there are still people in the DPRK who are good officials!

The new workshop is in the northwest corner of Chang'an City, next to Weishui, the workshop occupies a very large scale, according to Li Yifu's introduction, it can accommodate up to 1,000 people to work together, after all, the Ministry of Industry sometimes has to do some very large-scale projects, the demand for lime is very large, like this scale of lime workshop, there are several in other parts of the country.

As soon as Li Su entered the door of the new workshop, he saw Bai Qingzheng, who was wearing an eight-grade official uniform, commanding the craftsmen to transform the cement kiln, although the lime kiln could also burn cement, but after the research and improvement of the craftsmen who would be the supervisors in Bai Qing, a new cement kiln was invented, which could improve the calcination efficiency of cement.

"Your Highness, you can come, the lime workshop of this Ministry of Industry is different, even the big water wheel specially used for crushing." Bai Qing saw that Li Su was coming, and hurriedly ran over and said very excitedly. Because of his meritorious service in assisting Li Su in firing cement, Bai Qing, a petty official of the ninth grade, was finally promoted to one level, and now he is the signing order under the eighth grade, but he was transferred from the general supervisor to Li Su.

"Oh, there's a waterwheel? Take me to see it! Li Su was also very excited when he heard it, the ingredients of cement were crushed before calcination, but because the conditions were not enough when he was going to be imprisoned, he had been crushed by manpower, and the efficiency was very low.

"Yes, Your Highness, please come with me!" Bai Qing agreed, hurriedly turned around and left, he was too excited, he didn't even notice that there was still a person standing next to Li Su.

"Bai Qing, this is Li Yifu, the director of the Ministry of Industry, you have many aspects to cooperate in the future, let's get to know each other!" However, Li Su did not forget to introduce Li Yifu to Bai Qing, and Bai Qing was in charge of the internal operation of the new workshop, and Li Yifu assisted Li Su in managing the cement supervision institute.

"Uh~, Director Li is really young and promising, I was so excited just now, I neglected Director Li a little, and I hope you don't blame it." Bai Qing was stunned when he saw Li Yifu, and hurriedly saluted. Don't look at his grade is one level higher than Li Yifu, but he is a craftsman, and it would have been very difficult to be promoted, otherwise he would not have been a nine-rank petty official for almost a lifetime, and even if he was promoted, there was very little room for improvement, and it was already considered a top day to be promoted to six or seven grades. But Li Yifu is different, the head of the Ministry of Industry is a serious scholar, although it is only nine products now, but as long as the work is done effectively, there are nobles in the court to help, and it is not impossible to worship the prime minister in the future.

"Hehe, Bai Cheng is too polite, you are dedicated to the public, you are a model for my generation to learn, and the younger generation has just come into contact with this cement thing, and you will have to learn more from your predecessors in the future." Li Yifu still looked like he was smiling, and the words he said were still so beautiful.

Where did Bai Qing receive such compliments, and immediately regarded Li Yifu as his own nephew, and knew everything about his questioning. Li Su was also moved in his heart, it seems that there is no simple person who can leave a mark in history, not to mention the reputation of Li Yifu in history, but from his current point of view, this guy is definitely a rare talent.

After turning a few rows of lime kilns, Li Su saw a row of tall waterwheels standing by the Weishui River, slowly rotating under the impact of the water, and the sound of heavy objects hitting "Woo Woo Woo~" kept coming from under the waterwheel.

Li Su walked quickly to the waterwheel, the scene in front of him made him amazed, only to see each waterwheel through a simple machinery, driven by five metal hammers, when the hammer reaches the highest place, it will fall suddenly, using its own weight to smash the material in the groove below, there are two craftsmen standing on both sides of the groove, one is responsible for the stir-fry of the material in the groove, so that the hammer will smash the material more evenly, and the other is responsible for shoveling the smashed material to the trolley next to it, when the trolley is full, there is a special force to push to the front to mix calcination. Although the scene was full of dust, the craftsmen seemed to have a clear and orderly division of labor.

Although he didn't know Li Su, he knew Bai Qing and knew Bai Qing's boss, so he worked very hard to introduce the working principle and workflow of the waterwheel to them.

Li Su is also a person who has received general education in later generations, and his theoretical knowledge is stronger than anyone else, so after looking at it for a while, he found that the application of mechanical principles in some places is not very reasonable, but unfortunately there is no time to improve it now, so he can only wait for later.

After visiting the waterwheel, Li Su, under the leadership of Bai Qing, probably looked at the entire workshop again, most of them were very satisfied, and some unsatisfactory places Bai Qing was also rectifying, and Li Su didn't need to worry about it at all.

When leaving, Li Su instructed Bai Qing to prepare the previous cement stockpile, and try to speed up the production of cement, he will use it tomorrow, Bai Qing promised not to make a mistake at the moment, Li Su left with Li Yifu. However, before he arrived at his cement supervision institute, Li Su sent Li Yifu to the Ministry of Industry and asked him to ask a group of road builders to come back, and it will be done today, and Li Yifu was also ordered to do it.

Now it's not early, watching the sunset, Li Su is proud on the horse, cement is just a small thing, how to maximize its function is a big thing, now everything is ready, just wait for tomorrow to start action, then he will use cement to build a few long 'billboards', so that everyone can figure out what cement does, and then announce their plan, when the time comes......

"Hahahaha~" Thinking of the smugness, Li Su couldn't help laughing, causing the attention of the surrounding pedestrians, if it weren't for Li Su's gorgeous clothes and many guards around him, it is estimated that someone would have rushed up and arrested him as a psychopath!!
