At a quarter past noon, the Prince's Mansion. Li Chengqian had just finished eating and was lying on the Taishi chair, thinking about resting for an hour before calling Cheng Yanjin and Qin Qiong to inspect the Ministry of Industry.

However, Cheng Yanjin, the old horseman, insisted on pulling Qin Qiong into the prince's mansion and shouted loudly: "Nephew Gao Ming, is lunch finished now?" Let's go? ”

Li Chengqian was unhappy in his heart, but he didn't dare to express it. Because it was useless, he reluctantly walked out of the door and said to them, "When we have finished eating, let's go." ”

At three o'clock in the afternoon, I finally arrived at the Ministry of Works. Duan Lun, the secretary of the Ministry of Industry, hurriedly stepped forward to greet him: "Welcome to the prince." Prince Chitose Chitose Chitose. Li Chengqian got out of the car and replied: "Get up, take us in and see the generator you made." Cheng Biting Jin, Qin Qiong said excitedly: "Don't engage in these fictitious things, hurry up!" Li Chengqian looked at the excited expressions of these two old guys and shook his head speechlessly. So, Duan Lun didn't dare to slack off. He quickly led them to a large area with citrus trees.

Cheng Yanjin immediately became anxious: "Shouldn't you take us to the place where there is a generator?" How did you get to the farm? Didn't you only see a bunch of iron lumps when you came to the Ministry of Industry before? Aren't you kidding us? ”

Duan Lun laughed and said, "Don't worry about Lu Guogong, wait for me to take my time." ”

Qin Qiong also said: "Yizhen, don't worry. He must have brought us here for a reason. ”

Cheng Yanjin had no choice but to say, "Okay, I'll listen to what you say." ”

Duan Lun cleared his throat and said truthfully: "Yes, according to the information given by the prince. The finished product should indeed be a bunch of machinery, according to the prince, our technology, manpower, and material resources cannot keep up now. And we only learned about this technology and ideas from the prince, but it has only been a year. Therefore, it is impossible to complete such a good product in a short time, so we can only complete this generator in a simpler way. You all know by now that artillery needs shells, and fire needs iron eggs. Electricity also needs something to be generated, and of all the ways, only the way to generate electricity from fruit is the safest, most convenient, and most reliable. Although it consumes a lot of raw materials. ”

Qin Qiong said thoughtfully: "In other words, these citrus fruits are used to generate electricity, so where is the electricity?" ”

Duan Lun pointed to the iron pieces and wires connected to the citrus and said, "The electricity is in that." ”

Cheng Yanjin was taken aback: "This is electricity?" A bunch of wires and pieces of iron is it? As he spoke, he tried to touch it with his hand. Li Chengqian felt bad and hurriedly said, "Uncle, hurry up and stop!" Being beaten by electricity is life-threatening! ”

Cheng Yanjin said with a face full of disbelief: "I haven't seen anything in Lao Chen, how can I be frightened by just a few electric pieces and iron wires!" But he still obediently stopped, because, in the past, when inventing fire systems and artillery, he had a time when he almost died if he didn't listen to Li Chengqian. Now I have learned to be obedient, and when Li Chengqian said that his life was in danger, he only insisted on one or two words of obedience.

Li Chengqian smiled and said, "Your Ministry of Industry is very good, you can study to this extent; Now that I've learned how to generate electricity from plants, I can start making light bulbs the way I said. Also, we have to study the hydropower, wind power, and magnetic field power generation that I said. ”

Duan Lun saluted and said: "Humble obedience, thank you Your Highness for giving you this knowledge." ”

Li Chengqian then asked: "I want you to continue to improve the fire system and artillery. How's it going? ”

Duan Lun replied, "Your Highness, we can't go further now because of the material problem. We're looking at how we can elevate the material. ”

Li Chengqian approvingly: "This is a good thing, it shows that you have made a lot of progress." Let me go and see these artillery and artillery systems. ”

Duan Lun replied: "Okay, Your Highness, please." ”

Li Chengqian turned his head and said to Cheng Yanjin and Qin Qiong: "Two uncles, you can go back now." The next thing is more monotonous, discussing technical things. Because Li Chengqian knew that these martial artists were full of muscles, and they fell asleep when they saw the words and heard the boring physics discussions. (It's happened before, when I came to check on the fire system.) The Ministry of Industry discovered the deficiencies of the fire system and asked Li Chengqian about ways to improve it. And Cheng Biting Jin, who accompanied him, and Qin Qiong fell asleep after listening to it. And this time it's just a freshness, and now I've finished watching it. ）

So, Cheng Yanjin and the others laughed and left when they heard this.

Came to the workshop for the production of artillery and artillery. In accordance with Li Chengqian's arrangement, it has become very specialized, there are many steps that should be taken, and the secrecy work has also been done very well. In addition, it is not allowed to buy and sell these weapons without permission, and once discovered, they will be beheaded for public display (in the early days of making muskets, some people in the Ministry of Industry leaked secrets and made them privately. Under Li Chengqian's strong suggestion and the use of means to suppress them, all those people were beheaded for public display. The great majesty was established, which was also a reason why Li Shimin was relieved to give the Ministry of Industry to Li Chengqian. There is no ambiguity. In this way, all firearms are in the possession of only the royal family and the army. This also led to the real invincibility of the Tang Dynasty, which greatly reduced the damage of the Tang Dynasty army; After all, military technology is leading.

After coming to the working fluid room to understand the current smelting technology and temperature control technology, he proposed the method of using chemical reaction and the method of open-hearth steelmaking. It made them feel empowered and happy. However, they raised a variety of other questions.

After solving their various problems, Li Chengqian said: "I want all the certified engineers of the Ministry of Industry (Li Chengqian has personally selected and trained a group of craftsmen who can invent, create, and research in the 21st century) to appear here within half an hour, and I have something to announce." ”

The Ministry of Engineering did not dare to slack off, and hurriedly shouted people everywhere, and in less than half an hour, 100 engineers appeared in front of him. After they stood up, Li Chengqian said unhurriedly: "After some time, I will go to Longmen to make a county order and establish the first polytechnic university in Datang, and I want to take 20 outstanding engineers to be teachers and researchers." Those who are willing will come to my prince's mansion tomorrow afternoon to report and be tested. If passed, then you will shoulder the glorious responsibility of cultivating the next generation for Datang and making Datang stronger, and you will also be remembered by history and praised by the people and can get a rich fortune! ”

This made these engineers enthusiastic when they listened, and they all wanted to be the first to go to the prince's mansion to report.

Li Chengqian looked at their expressions like chicken blood, and felt a pain in his heart and thought: It seems that tomorrow will not be idle.

But Li Chengqian is really happy that he can change so many places in this Datang.

In this way, after bidding farewell to Duan Lun, the secretary of the Ministry of Industry; When I returned to the Prince's Mansion, I quickly washed up and went to bed. He also muttered: "Hey, this prince is so tired." But he smiled happily......
