In five days, Li Hao was in the office and had never returned home. He finally finished reviewing all the test papers. In fact, this test paper was not difficult. If the veterans who had fought wars answered, it would probably be half of them could answer it. But at present, these recruits are new recruits and have never fought a war. The exam is just a test of their mentality. Even if the answer given by someone is not realistic, if they can open their brains, Li Hao will let him pass it. But if the answer is lifeless and stick to the rules, he will only be eliminated. What Li Hao needs is talents, talents with innovative spirit.

Among the 20,000 test papers, only 120 people met Li Hao's requirements, and the elimination rate was comparable to the imperial examination. Li Hao cleared the test papers again. Eighty-five of them were illiterate. Among these illiterate illiterate, forty of them were under 18 years old, accounting for nearly half. The answers from these forty young people made Li Hao very satisfied. Among them, one of them made Li Hao very happy because this person was a famous general in history. However, he is still young and only sixteen years old. His name is Wang Xiaojie.

Wang Xiaojie was a famous general during the Wu Zetian period and had high military talents. Unexpectedly, he was attracted to him as soon as the Tiance Mansion was opened. It was really a surprise.

Li Hao immediately began to formulate learning courses for these 120 people. Eighty-five illiterate people gathered together and were classified as Tianzi Class No. 1, and the remaining 35 people were classified as Dizi Class No. 1. Tianzi Class first started with simple teaching and mathematics courses. There were two classes a day, each class was one hour, that is, half an hour, and a year, and a new course will be added in six months, military theory courses, and classes will be held on the fifth, fifteenth and twenty-fiveth day of each month.

As for Class 1, it directly starts the military theory course, which Li Hao personally teaches. If he is not available, he will invite Li Ji or other famous futures to substitute the class. This is the key to cultivating talents and cannot be delayed.

Whether it is Tianyi or Earth Class, their training will be carried out as usual. Not only that, the training intensity will also be increased, and it will increase to the difficulty of special forces in the later stage, which will last for two years. After two years, the Tiance Mansion will assess the students of these two classes. If the performance is too poor, they will be kicked out of the elite class.

Soon, the various plans formulated by Li Hao began to be implemented smoothly, and the courses of the two elite classes began, and the training intensity of the two elite classes also increased, and a quagmire training was added. It is said that one new training will be added every month in the future.

Although Wang Xiaojie is a famous historical general, Li Hao did not give him special care, and even did not deliberately pay attention to him. Wang Xiaojie may be a talent. Since he is a talent, he will always stand out. If he doesn't have that ability, Li Zhi can only say sorry.

After twenty days, these recruits gradually began to adapt to the high-intensity training formulated by Li Hao. The training was very difficult, and they had to train for at least six hours a day. Even eating and taking a bath had time regulations, which was only 2 minutes (Li Hao installed a clock in the military camp and popularized the calculation method of the future world to them). They always felt that they were racing against time.

In fact, they don’t know that the training of the two elite classes is much harder than that of them. Not to mention the intensity of the training, just talk about the time of eating and taking a bath. Eat for 1 minute and take a bath for 1 minute.

Although the training was difficult, Li Hao did not treat them badly. The food was of good quality. Not only did he take full care, but he also had meat almost every day. He would also eat extra meals after the night training camp. This can be said to be a very big temptation for this group of recruits. Most of them were from poor peasants and were used to farm work. In ancient times, they were very tiring to do farm work. They could endure hardships, but they could not stand hungry. As long as they could eat enough, they could accept it.

The Tiance Mansion was finally getting on track, and Li Hao hadn't been home for a long time. He took the time to go home, went back to the mansion to have dinner with his wife and children, and then took a shower and slept beautifully. When he woke up and just walked out of the room, he saw Cheng Qingyun standing respectfully outside the door waiting.

When he saw Li Hao coming out, Cheng Qingyun hurriedly saluted: "Greetings to the teacher."

Seeing this, Li Hao asked in surprise: "Hey, why are you here?"

Since the construction of the Summer Resort in Lantian, Li Hao has rebuilt the school next to the Summer Resort. Now the students and all the people in the scientific research department have moved there. Cheng Chuliang is a science madman. In order to do scientific research, he lives in the scientific research department for many years and has not been home for two years. He came to see him this time, and there must be something wrong.

"Teacher, have you mentioned the generator before? I made it." Cheng Qingyun suppressed the excitement, but it seemed useless. His face was full of smiles.

"Take it seriously!" Li Hao was also surprised when he heard this, so he hurriedly asked, "Where is it?"

"It's in the school's research department." Cheng Qingyun said, "That thing... can't be moved."

"Let's go and have a look." Li Hao hurriedly pulled Cheng Qingyun out, asking people to prepare horses while running.

Li Hao and Cheng Qingyun rushed to Shanghe Village in Lantian in a hurry, and built a school across the river to the south of the Summer Resort. The school was quite large because there are more than 1,800 students in the school and more than 30 teachers. There are more than 4,000 students who have graduated in these years.

Li Hao and Cheng Qingyun came to the physics research room. Four scientific researchers in the research room were doing research work. Li Hao saw a guy fiddling with a big machine at first sight. He was shocked and felt that the machine was not simple. Without waiting for him to ask, Cheng Qingyun explained: "I and others are studying the steam engine you mentioned in the past two years. Although it is roughly formed, it has not been completed yet, so I have not reported it to you."

"Okay, very good, done well, keep working hard!" Li Hao was very excited. He came to see the generator himself, but he didn't expect to see the steam engine. Although the steam engine has not been completed yet, Li Hao believes that it is just a matter of time. Steam engines, something of epoch-making, is an invention that is even greater than a generator.

Li Haoqiang was excited, Cheng Qingyun and other scientific researchers took Li Hao to the middle of the scientific research room, and saw a huge pillar standing on the ground. The pillars were more than one person tall, all made of steel, and the shape was very complicated. Li Hao asked in surprise: "Is this the generator?"

"Yes." Cheng Qingyun nodded and gave a look to other researchers. Other researchers hurriedly started wiring.

In this era, there was no rubber. Their wires were all bare wires. Fortunately, all wires were straight and did not touch anything else, so there would be no danger. The wire was connected to a huge light bulb. The light bulb was also developed by them. It was made of tungsten wire, but the tungsten wire was a bit thick and needed a large current to light up. In fact, in this era, the biggest difficulty of the light bulb was not the filament, but the exhaust. There was no air inside the light bulb. The most primitive light bulb was filled with a vacuum. Later, argon gas was filled with a relatively stable argon gas, and it was not combustible and did not help burning. It could make the internal air pressure of the light bulb similar to the air pressure, so that the bulb would not explode easily.

Cheng Qingyun and his scientific research laboratory have long developed various things that transcend this era. They have the ability to extract the air from the light bulb, but... when pumping, the light bulbs are prone to burst, so the light bulbs here are very precious.

After connecting the wires, Cheng Qingyun introduced: "Teacher, when you built the school, you asked the school to cross this river and said that this river was of great use. I didn't understand at first, but now I finally understand that my generator uses the water of this river as power. However, it took a lot of time to build this dam. As long as I open the sluice gate, the water flow will drive the generator. The generator starts to operate and generate electricity, and can light up the light bulb."

"Please start your performance." Li Hao smiled and spread his hands. He was really looking forward to it. Although the generator was a little small and a little simple, it was just a prototype. As long as the generator was successful, the subsequent improvement work would be simple.

"Yes!" Cheng Qingyun whispered loudly, "Open the water gate!"

The two scientific researchers immediately began to push the spindle, and then they heard the generator turning sound. The noise was quite loud. There was no way. The current process was not perfect enough, so it was inevitable that there was noise.

As the sluice opened, the generator turned faster and faster, and the huge light bulb became brighter and brighter. The filament went from being slightly red at first to finally emitted a dazzling light, like a small sun. The temperature in the whole room seemed to have increased. There was no way. The bulb was too big and the filament was thick, so the power was naturally high. It was precisely because the filament was thick that it could withstand the powerful current provided by a generator. However, Li Hao could feel that the bulb was overloaded and the filament probably wouldn't last long.

Sure enough, within a few minutes, the light bulb suddenly emitted a strong light, and then it became dark in an instant. The filament broke. Everyone's eyes became accustomed to the high-brightness light, and suddenly there was no light. Even if there was some sunlight in the room, they felt dark in front of them.

"Okay, it's really successful." Li Hao said with a smile, "And it's AC, Cheng Qingyun, you really didn't disappoint me."

"It's all well trained by the teacher." Cheng Qingyun saluted excitedly. To him, the praise of 100,000 people was not as useful as Li Hao's praise.

"Next, you will find a way to improve the generator and increase its power. At the same time, scientific research on power storage must be carried out. Power storage technology is not that easy. You need to use all the knowledge you have learned. If you don't understand, go directly to Chang'an to ask me."

"Yes, teacher."

Li Hao continued: "This wire is too dangerous. I know there is something called rubber. It is an insulator with a very soft texture that can be used to wrap wires. I will order people to build rubber factories and wire drawing factories to produce rubber-wrapped wires, and then transport them to you for research. If you can successfully study the steam engine, I will invest in building a small steam engine power plant. First, we use our school as the power supply test site. Our school will be the first place in the world to use electricity!"

"Thank you, Prince!" Cheng Qingyun looked at Li Hao excitedly. He could almost imagine that a few years later, the whole school would be brightly lit everywhere even at night. What a beautiful picture it would be.

Li Hao turned his head and looked at the steam engine, and fell into imagination with a smile on his face. The emergence of steam engines and electricity has changed the world the most tremendously. These will be the two deepest footprints of technological progress. It was these two things that made European countries make rapid progress during the Industrial Revolution, far surpassing China for decades, and later China's tragic history.
