On the second day after the establishment of Li Su's cement supervision institute, a very ordinary thing attracted the attention of many people. In the most prosperous east and west cities of Chang'an, the two main roads began to be renovated at the same time, and the construction of one side turned out to be the newly established cement supervision institute, many people know that Liang Wang Li Su was appointed as the cement supervision envoy, so at the beginning there were many people concerned about the cement supervision institute's every move, but I didn't expect Li Su to take office after not doing business, put down the cement production business, but robbed the name of the Ministry of Industry to start building roads?

There were a few supervisors who couldn't look past it, and immediately impeached Li Su for exceeding his power, but he was criticized by Li Shimin, because Li Su used cement to build roads, and the cement superintendent was in charge of all cement-related affairs, so this is not the right of the cement industry association in Chapter 42. Although this reason is barely said in the past, anyone with a discerning eye can see that this is obviously Li Shimin favoring Li Su, and it is true that cement is used to build roads, but road construction is a matter within the Ministry of Work, Li Suda can only provide cement, and then let the Ministry of Industry send someone to repair it, and there is no need for his cement supervision institute to come forward.

But with the construction of the two main roads, everyone's attention was drawn to the road itself, and no one cared who built it anymore. Because as long as people who have seen the cement road, they will be shocked by the smooth as a mirror, hard as a stone cement pavement, in the eyes of the Tang people, a pile of floury cement and sand stone are mixed together, and then poured on the road after smoothing, after a few days it will become like a stone, which is simply incredible. Therefore, when the road is being built now, there is always a group of good people who follow them, and they can't get rid of them, and even many people make a special trip to the east and west cities to watch. With the flow of people in the east and west cities, almost everyone in Chang'an now knows about cement, a magical thing, and also knows that the person who invented cement is King Liang who held the banquet of the five kings before, and for a time the name of Li Su once again became the focus of the entire Chang'an.

On this day, Fang Xuanling had just finished the morning court, and he was about to return to Zhongshu Province to deal with government affairs, but he didn't expect that Chapter 42 Cement Industry Association was stopped by Li Shimin, and he had to take him to see the cement pavement repaired by Li Su. Fang Xuanling, as a Zhongshu Ling, had a lot of affairs on his body, and he didn't want to go, but Cheng Jin, who was beside Li Shimin, was dragged hard, and in the end he could only go with them. All of them changed into civilian clothes, in addition to Li Shimin, Cheng Yanjin and Fang Xuanling himself, there were also Li Jing and the eldest grandson Wuji, just two liters and two martial arts plus an emperor.

A group of five people came to the East Market, the first thing they saw was a busy scene, the main road of the entire East Market was divided into two halves from the middle, the right side has been paved with cement, and it has also been hardened, and now it is ready to leave. The part on the left is also under construction, only to see the craftsman use a wooden board to divide the road surface into a rectangle, and then pour the mixed concrete into it little by little, there are craftsmen in it to smooth out the performance, but in a few quarters of an hour, a section of more than ten meters long cement pavement will be repaired, and then let it dry for a period of time, and when the surface is almost condensed, it will be paved with straw and wait for the shade to dry.

"This speed is too fast, from the time Rokuro started to build the road to now, it has only taken more than ten days, how can the main road in the East City be repaired by more than half at once?" Li Shimin looked at the road surface that was quickly covered by cement, and said with some hesitation.

"Your Majesty, in fact, this is His Royal Highness King Liang playing tricks!" Fang Xuanling understood it, smiled and pointed to the places where the roads were built and whispered, "Your Majesty, please see, those craftsmen are just laying cement on the original road surface, because this road is originally paved with bricks and stones, which is quite solid, just pave a layer of cement, but if you want to build a new road, you must first smooth and tamp the road surface, and then you can pave cement, and the speed at that time is much slower." ”

"Haha, I didn't pay attention to this!" Li Shimin took a closer look, and sure enough, as Fang Xuanling said, he smiled.

Li Jing and Cheng Yanjin walked curiously to the repaired road, first stomped with their feet, and found that it was almost the same as the cement slab they saw that day, and now the repaired half of the road has begun to be used, there are many pedestrians and vehicles on the road, and many people are like Li Jing and Cheng Yanjin, very curious about the smooth and hard cement pavement under their feet, and some people even bent down to touch the road, almost exactly the same as Li Shimin when they first saw the cement.

"Your Majesty, if you don't see it with your own eyes, you really can't imagine that there are so many benefits of cement pavement, if the whole country uses cement to build roads, not only do you not have to worry about the rain in the future, but also when the carriage transporting goods travels on it, the speed can run faster, and save horsepower, in the old minister's estimation, if a horse-drawn carriage can run a hundred miles a day in the past, then it can run three or four hundred miles a day on the cement road, and in the future, whether it is transporting grain and grass or soldiers and horses, it will be several times faster than before." Li Jing also came back with an excited face to report, although they were out on patrol in civilian clothes, they had guards around them to separate the people around them, so they were not afraid that someone would hear their conversation.

"What the pharmacist said is good, if the cement road is built, it will not only be of great use in the military, but also can speed up the circulation of goods in various places, make all industries more prosperous, and the people will be richer, which is really a feat that will benefit the future!" Li Shimin also said with emotion, if he still had some doubts about building roads in a big way before, now after seeing the half of the street that has been built, he immediately strengthened his confidence in building roads, but he didn't find that the eldest grandson Wuji behind him was full of gloom.

Li Shimin walked around the cement road with great interest, listened to the discussions of the people around him, and found that most of the discussions were about cement and Li Su, and the rumors about Li Su aroused his interest.

Li Su's previous bastard appearance was known to the whole Chang'an, but since the last time he was injured and lost his memory, he began to show a unique talent, which is extremely legendary. Therefore, there are many rumors that Li Su has the royal blood of the two dynasties and his status is extremely noble, so he is favored by the gods and can teach the heavenly divine arts, so he began to become so extraordinary. And the rumors are also well-documented, for example, the five kings drunk is actually the heavenly immortal brew, cement is the legendary Yu used to control the water, etc., anyway, one is more outrageous than the other, but the more outrageous, the more the people like to listen.

For these rumors, Li Shimin laughed after hearing it, he didn't believe in the nonsense that the gods took a fancy to Li Su, if there were really immortals who took a fancy to his son, it should also be because of Li Ke, no matter from which point of view, Li Ke was much stronger than Li Su before.

However, some people praise their son, as a father Li Shimin is still very happy, and recently Li Su has indeed been angry, and the literary talent he showed is shocking, not to mention, he offered cement, a strange thing that benefits the country and the people, and also helped himself set a strategy to destroy Liao, which really made him a big face as a father, and even the smile on Concubine Yang's face has increased recently.

After going around the East Market for a while, Li Shimin and the others went to Li Su's cement supervision institute again. Now that the sign of the Superintendent has been hung up, there are two officials standing at the door, and they look very good.

Li Shimin's guards went up and flashed the sign of the guards, but the officials did not dare to stop them and immediately let them go. But before they could go in, they saw a few servants hurrying out of it, as if they were still holding something in their arms. Li Shimin and the others didn't care, and walked straight to the office hall inside.

"Your Highness, for every ton of cement produced, merchants have to pay a royalty of 20 yuan, isn't this too little, according to this calculation, we don't seem to be able to collect much money a year?" Before Li Shimin could enter, he heard a young voice inside asking loudly.

"Hehe, Yifu, you still underestimate the output of cement, the country is about to overhaul the cement road, this needs cement is not a little bit, according to my estimates, at least millions of tons per year, and after the people see the various effects of cement, it will definitely attract a lot of people to use, they are the big users of cement, there is no output of millions of tons, can not meet the needs of the whole country, so calculated, a year to collect 100,000 yuan of patent fees, or more than enough." Li Su said in a slow tone, his voice looking very tired.

"But this is only when the market reaches its maximum, and the demand for the first few years will certainly not reach a few million tons, so we will not be able to reach the minimum cost promised to His Majesty in the first few years." The young voice spoke again.

Li Shimin's face was stunned when he heard this, which reminded him that in order to take charge of cement affairs, Li Su had promised him that he would pay at least 100,000 yuan a year, and listening to the content of their conversation, this fee seemed to come from the 'patent fee'. It's just that what Li Shimin doesn't understand is, what is that 'ton', it sounds like it is used to calculate cement production?

"It doesn't matter, there are so many craftsmen under the Supervision Institute, in addition to some who have the ability to study the improvement of cement, most of the others can also be used to produce cement, and the profits from the sale of these cement can be used to make up for the lack of royalties, and maybe there will be a surplus." Li Su seemed full of confidence, and it seemed that he had really put a lot of effort into this area.

"Well, in that case, it works." The young voice groaned for a moment, and then said again with a wry smile, "Your Highness's plan has been clarified, and it is indeed feasible in theory, but for the 'Cement Industry Association', the lower officials are still a little worried, after all, no one has ever done this since ancient times." ”

"Hahaha~, no one has done it, we just want to create a new model, let everyone follow our model, no matter what kind of industry in the future, we must copy the operation of the cement industry association, this is a good opportunity to leave a name for the ages, and it is also a good opportunity for your Yifu brother to get ahead." The camera pulled into the office hall, Li Su was half-lying on the chair with two dark circles under his eyes, and said to Li Yifu excitedly.

In the past few days, he has to organize craftsmen to build roads, and he has to write the regulations of the Cement Industry Association.

In fact, Li Su's idea of cement operation is very simple, that is, to imitate the patent model of later generations, and the cement supervision institute will provide technology to attract those powerful people from all over the country to invest in the construction of factories, and then for every ton of cement they produce, Li Su will collect 20 yuan as a patent fee. Li Su represents the most powerful imperial power in feudal society, so he is not afraid of others defaulting on his debts at all. As for the cement industry association, it is a semi-official organization that manages all cement manufacturers, mainly to coordinate and deal with the difficulties and problems encountered by various cement manufacturers, and to hold a general meeting of manufacturers in the association every year to agree on the price of cement in various places in the next year, after all, the manpower and prices in each place are different, and it is impossible to unify the pricing, unless all factories are placed in the same area, but this is obviously not realistic.

Today, Li Yi called Li Yifu to explain to him, after all, he would definitely not be able to do such a big thing alone, and it was a bit of a waste to have such a good helper as Li Yifu. But Li Yifu, as a traditional scholar, couldn't adapt to Li Su's advanced ideas for a while, so Li Su spent a lot of words.

"But...... Xia Guan really didn't have much confidence. Li Yifu is still obviously lacking in confidence, after this period of getting along, Li Yi's temper has been touched through by him, knowing that His Royal Highness King Liang has always been informal, and he can usually gain his favor by being casual in front of him, so Li Yifu slowly took a lot less care. He really didn't have confidence in this matter today, so he hesitated again and again, but he didn't have to worry that Li Su would be blamed for this.

"Okay, the matter is settled, you will be the vice president of the Cement Industry Association in the future, and I have already asked people to post the notice, maybe someone will come to inquire tomorrow, you should prepare well." Seeing that Li Yifu was still hesitating, Li Yi simply pressed it down directly, and made a decision for him with a wave of his hand.

"The eldest husband should have the courage to 'dare to be the first in the world', but my mother-in-law and mother are not my generation?" Li Su then encouraged. Li Yifu slandered in his heart: You are the boss who said it is light, but it is still us petty officials who do the specific work!

"Good! What a 'dare to be the first in the world'! Su'er, you really deserve to be my son, hahaha~" At this moment, Li Shimin, who had been listening outside for a long time, praised loudly, if he hadn't heard it with his own ears, he really couldn't believe that his son had such courage?!!!
