The person arranged for the five yarn machines that had been placed together on the carriage, and then proposed the five other yarn machines in stock from the warehouse, and a total of ten yarn machines were loaded and transported to the exhibition that was about to begin soon.

Li Hao looked at the carriage and left, and suddenly slapped his thigh: "Oh, look at my brain."

"What's wrong?" Li Xueyan, who was still immersed in the 500,000 points, came back to her senses and asked with concern.

Li Hao waved his hand and turned to Yuan Tiangang and said, "Old Yuan, have you tried these yarn machines?"

"Of course I tried it." Yuan Tiangang said naturally: "If I haven't tried it, how can I know the magic of this thing?"

The magic of the yarn machine was not needed by Yuan Laodao to say that Li Hao already knew. Seeing him say this, he immediately said: "Where are the yarn worker you used to test the machine? Where are the people now?"

"Shadow?" Yuan Laodao reacted for a while before he realized what Li Hao was saying. He complained: "Criminal, the college is very cautious. Even if the third or fourth rank officials cannot enter without His Majesty's order, how could there be any shadow? The one who tested the machine was just two unsatisfactory apprentices."

Only then did Li Hao remember that the Technical College was already very different from his original idea. He scratched his head and said, "Then you can lend them to me, don't worry, I will only borrow it for two days."

At the beginning, he just wanted to set up a school to train his capable subordinates and teach them some basic mathematics, physics, chemistry and other things in future generations, so as to facilitate the development of some work in the future.

But unexpectedly, after entering the academy, these Taoist priests and some craftsmen with superb skills were immediately fascinated by the various disciplines proposed by Li Haoli. They hugged Li Hao's primary physics and primary chemistry that he wrote, and called it "I don't learn how to teach students."

Later, as the Taoist priests became more knowledgeable and their minds were no longer on teaching students. They used the knowledge they learned to start using public instruments and tinker with things like alchemy.

Seeing that this was not a solution, Li Hao could not throw the academy that he had spent a lot of money to those Taoists to play, so he simply stopped recruiting students and threw them a few projects, such as sulfuric acid, nitric acid, smokeless gunpowder, and even improved iron smelting technology formulas, glass manufacturing technology, etc.

After a while, the nature of the Technical College gradually developed from the original educational institution to the scientific research institution. Until the successful development of smokeless gunpowder, the college attracted Li Er's attention. In order to prevent accidents, an imperial guard from the palace was specially transferred from the palace to be responsible for the escort work here, and strictly ordered anyone to enter without any intention.

The Technical College has also gone from being ignored at the beginning to the most mysterious place in everyone's eyes. The projects under study have also begun to become more and more high-end, and the scope has become wider and wider. This is why the college spends money like water.

When Yuan Tiangang heard that Li Hao was going to borrow someone, he immediately became nervous: "What do the prince wants to borrow them for? Is the two incompetent disciples currently carrying heavy responsibilities, so I dare not leave for too long."

"Why are you so stingy? You just borrow two people." Li Hao ignored Yuan Tiangang's thoughts, looked down on him, and turned to Li Xueyan and said, "The sales of the spinning machine will be handed over to you. Let's take care of it when you look at it. In addition, you can pick two smart girls from the house, and learn how to use the yarn machine with Old Yuan's apprentice, and then demonstrate it to those foreigners."

Speaking of serious matters, Li Xueyan was not vague and nodded slightly. This was not the first time such a thing was. She just sent an additional manager to watch: "Don't worry, I will send the most capable person."

Yuan Tiangang thought Li Hao was going to poach him, but he was so nervous. Later, he found out that he was just going to teach on site and felt relieved. He took a lot of money and said: "You can rest assured to teach disciples like this. The bad disciples guaranteed to teach the church."

That's right, isn't it just four broken spools and a shaker? As long as you are not a fool, you can basically see it at a glance.

Li Hao rolled his eyes and continued the next topic: "Old Yuan, this time I brought Princess Xueyan over here, mainly to let her come here to take charge of some things. You see if there is still an empty venue in the college, and get a textile institute out."

As one of the main leaders of the college, Dean Li Chengqian was absent from his name and the financial owner Li Hao was fishing for three days and two days of drying the net, although Yuan Tiangang did not have the name of the top manager of the college, he was the top manager.

He lowered his head and thought for a moment and nodded, "If this is the case, I think it would be better to change the name of this Machinery First Hospital directly. The manpower is enough to be arranged according to the princess."

"Then let's decide this way. The First Academy of Machinery is converted into the Textile Institute. It is mainly responsible for the research of spinning machines and looms, and try to simplify its operation steps and reliability of use." After saying this, Li Hao smiled at Li Xueyan and said, "In the future, you will be the main person in charge of this small building. Don't be lazy."

"Ah, I'm the person in charge here?" Li Xueyan never figured out what Li Hao was going to do from the beginning to the end. All arrangements were so inexplicable. She blinked her beautiful eyes and said in confusion: "Why is this? I, I'm afraid I can't get it."

Li Hao smiled slightly: "It's okay, just let go and do it. I'll take care of it if something happens."

Before they knew it, the two of them fed a handful of dog food to the handsome Chunyang guy beside him, and they made Lao Yuan leave and coughed awkwardly: "That... Prince, I see that it is the first time that the princess has come to our place. Why not take you and the princess to visit here?"

"That's good. I've been here for more than half a year. I'm just going to see what new things you are doing, Lao Yuan."

With Yuan Tiangang's greeting, someone immediately rushed to the carriage with an internal pass in the college. Li Hao and others got on it, and the carriage immediately moved and drove towards the depths of the college.

The space in the carriage was very spacious, and no one seemed crowded when seated in four or five people. Facing Li Xueyan's curious eyes, Li Hao explained: "This is a carriage specially used for passing through the college, so it was made a little bigger."

Li Xueyan said: "Why do you need to prepare a carriage in the academy?"

"Because this place is too big, if you really want to leave, I'm afraid I can't walk all the places here all in two days." Yuan Tiangang said with a smile: "But it's a blessing for the prince to make this place so big. Otherwise, I wouldn't know where to place so many research projects."

"Master Yuan, do the college have many research projects?" Li Xueyan's eyes were filled with a strong desire for knowledge.

Rather than saying that she wanted to know the research projects in the college, she wanted to know how the 500,000 yuan spent within half a year, but she asked very skillfully.

As expected, he is a good wife and can get married with such a girl. I don’t know what luck Li Hao has left.

Yuan Tiangang is also a person who has seen the world. How could he not hear the meaning of Li Xueyan's words? He now showed off his professional skills that are not inferior to those of the tour guides in later generations. He pointed outside and said, "Prince, please look at the right side. The right side is the Chemical Institute of the College, which can also be called the Chemical Branch. Currently, the main research projects of the Chemical Branch are sulfuric acid, nitric acid, and water spray proposed by the prince."

"What is 水水?" Li Xueyan asked incitement, looking like a curious baby.

"Fengshui is a kind of burning black liquid, you can also call it oil." Li Hao explained, then looked at Yuan Tiangang with a surprise and said: "I didn't expect you to study Fengshui, I thought you would use it as tinea oil."

"No, no, no, prince, Fengshui is not as simple as you think." When it comes to the research project of the college, Yuan Tiangang seemed to have changed his personal life, becoming a little crazy: "If I didn't say it, you would never have thought of what the Chemical Institute found in Fengshui."

"What did you find? You won't find air kerosene inside, right?" Li Hao joked.

When talking about oil in Datang, Li Hao probably wouldn't know anyone better than himself. No matter how powerful Yuan Tiangang is, can he still play oil with it?

Sure enough, countless question marks appeared on Yuan Tiangang’s brain: “What is aviation kerosene?”

"Nothing, you can continue to count the water." Li Hao waved his hand and did not explain what aviation kerosene was.

This thing is too complicated, and it is difficult to understand just kerosene. If it is added with aviation..., the audience will have to ruin their views.

Yuan Tiangang didn't mean to ask the question in the bottom line. The key was that he knew that if Li Hao didn't want to say it, he would ask in vain if he asked. He paused and said, "After distilling the water, the Chemical Institute discovered a solid substance that can melt at a certain temperature and has a very high viscosity..."

Before Yuan Tiangang finished speaking, Li Hao was not calm.

As far as he knows, one of the ways to extract asphalt is oil distillation, and according to Yuan Laodao's description, the black substance he described is indeed very similar to asphalt.

Damn, are these old lunatics completely letting themselves go?

Li Hao no longer knew how to express his admiration for Yuan Tiangang. He was so arrogant that he could not say anything: "Damn, you didn't study the asphalt, right?"

Yuan Tiangang automatically ignored the interjection of "告" and continued: "I don't know what the asphalt is mentioned by the prince. I only know that this object can be used for waterproofing and can also be used to dip in some items."

Li Hao shook his head, "No, the biggest function of this thing is to build roads."

It is not unreasonable for him to say this. After all, the more advanced houses in the Tang Dynasty are basically topped with tiles, while the people's houses are mostly topped with thatch, and they live in asphalt... What if it burns?

But then again, according to the current industrial level of the Tang Dynasty, using asphalt to build roads would probably be able to build a road from Chang'an to Baqiao in a hundred years, which is not worth it.

But no matter what, the appearance of asphalt is a good thing. At least Li Hao thinks that building a house by himself can be used to repair the roof for waterproofing in the future.

Just as he was thinking, Yuan Tiangang took out a flat small box from his arms and put it in front of Li Hao: "Criminal, look at this thing."

"What is this?" Li Hao picked it up casually, saw a small button on it, and then pressed it casually.

At the next moment, the flat box popped open with a "bang", and a dazzling light flashed, and Li Hao froze.

Li Xueyan leaned over her head curiously, and when she saw it, she also exclaimed: "Ah, this is a mirror?"

I dare to feed the old Taoist dog food, let’s see how I take revenge on you. Yuan Tiangang was very satisfied with the shock brought to the two of them by the small flat box, and laughed and said, “Haha, it’s the mirror, princess, this is the latest achievement of the Chemical Institute. It was only sent to my residence last night.”

"Dejian, come and show me." No matter how reserved Li Xueyan was, she could no longer remain calm in front of the visible mirror. She snatched the flat box in Li Hao's hand and looked at it in front of her.

But I saw a beautiful face reflected on the lid of the small box. I tilted my head slightly, and the people in the mirror moved with it, gently stroking my cheeks. The people in the mirror's blown and shaved their skin.

A scholar died for his confidant, and a woman satisfies him for his pleasing himself. This was the first time Li Xueyan saw himself in the mirror so clearly. After a long time, he sighed: "This, this mirror is so clear. Master Yuan, don't you know if this thing is willing to give up?"

Li Hao looked at the sweetheart around him speechlessly, and he was in a bad mood.

It was not because of Li Xueyan's obsession with the mirror, but because she was annoyed that she had not thought of such a simple God of Wealth.

Glass has been researched for a long time, glass cups, glass windows, and telescopes have been sold all over the world, but the mirror has not been created. It is really stupid to think about it.

Sighing, Li Hao smiled at Li Xueyan: "If you like it, put it away. What should you cut or not? Isn't it just a piece of glass and spray a little mercury? This thing is worth as much as you want, it's not worth it."

"Really?" Li Xueyan didn't believe it, and put down the small box in her hand and looked at Yuan Tiangang.

Yuan Tiangang, who was still proud of his face, changed his face and smiled bitterly: "It turns out that he can't hide anything from the prince. I was very sorry that I originally planned to keep it a secret. Now it seems that the prince is a scholar and a sensible person, and he can tell the whole story of the whole leopard, which is not something we can do."

"Don't flatter, it's useless." Li Hao took the conversation unhappily: "You said that it's just such a broken thing, and it's worth your hard work to study. What exactly are you guys putting on your mind, granite?"

Yuan Tiangang was so ashamed that he was said, he hung his head and couldn't even say anything refuted.

The pressure is so great. Is there anything this guy doesn't know about? There is asphalt in front and mirror in the back. The things that the chemical industry can take out are not worth a penny in the eyes of the other party. After only opening it, the other party has already told all the key points.

If I had known this, why would the Chemical Institute have studied it? I would just ask if there were any questions.

Li Xueyan felt a little embarrassed, touched Li Hao gently, and then smiled and said, "Dejian, I think this mirror is pretty good. If the price is right, it may not be impossible to recover the cost you invested before."
