Five days, Li Hao ate and lived in the office, never went home, and finally finished reading all the test papers, in fact, this time the test papers are not difficult, if you give those veterans who have fought to answer, it is estimated that half of them can answer, but at the moment this group is a new recruit, who has never fought, the exam is just a test of their mental activity, even if someone gives an answer that is not very realistic, but if you can open your mind, Li Hao will let it pass, but if you answer lifeless and conformist, then you can only be eliminated, What Li Hao needs is talents, talents with innovative spirit.

Among the 20,000 test papers, only one hundred and twenty people meet Li Hao's requirements, the elimination rate is comparable to the imperial examination, Li Hao liquidated the test papers again, among which eighty-five people are illiterate, among these illiterates, there are forty under the age of eighteen, accounting for nearly half, and the answer sheets of these forty young people make Li Hao very satisfied, among them, there is one person who makes Li Hao very happy, because this person is a famous general in history, but now he is still young, only sixteen years old, his name is Wang Xiaojie.

Wang Xiaojie was a famous general in the Wu Zetian period and had high military talent, but he didn't expect to be recruited as soon as the Tiance Mansion opened this time, which was really unexpected.

Li Hao immediately began to formulate a study curriculum for these 120 people, 85 illiterate people gathered together, was classified as Tianzi No. 1 class, the remaining 35 people were classified as Dizi No. 1 class, Tianyi class first started with simple teaching words and mathematics courses, two classes a day, each class for an hour, that is, half an hour, for a period of one year, six months later, there will be a new course, the art of war theory course, the fifth day of each month, the fifteenth, twenty-fifth class.

As for the first class, it is to start the art of war theory class directly, taught by Li Hao himself, if he is not available, he will ask Li Ji or other celebrities to substitute for him, this is the key to cultivating talents, and it cannot be delayed.

Whether it is the first class of the day or the first class of the earth, their training is carried out as usual, not only that, but the intensity of the training will be increased, and the difficulty of the special forces will be increased in the later stage, for a period of two years, after two years, the Tiance Mansion will assess the students of these two classes, and if the performance is too poor, they will be kicked out of the elite class.

Soon, the various plans formulated by Li Hao have begun to be implemented smoothly, the courses of the two elite classes have begun, and the training intensity of the personnel of the two elite classes has also increased, and a quagmire training has been added, and it is said that a 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 did not even pay attention to him deliberately at all, Wang Xiaojie may be a talent, since he is a talent, he will always stand out, if he does not have that ability, Li Zhi can only say sorry.

After 20 days, these recruits gradually began to adapt to the high-intensity training formulated by Li Hao, the training was very hard, at least six hours a day, and even there was a time limit for eating and bathing, only 2 minutes (Li Hao installed a clock in the barracks and popularized the method of calculating time in 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 theirs, not to mention the training intensity, let's talk about the time to eat and take a bath, 1 minute to eat and 1 minute to take a bath.

Although the training is hard, Li Hao did not treat them badly, the quality of the meals is good, not only full, but also almost every day there is meat to eat, and there will be additional meals at the end of the night training, which can be said to be a very big temptation for this group of recruits, most of them are poor peasants, and they are used to doing farm work, in ancient times, they were very tired of doing farm work, they had to endure hardship, but they couldn't stand hunger, as long as they could eat enough, they could accept it.

Tiance Mansion is finally on the right track, Li Hao hasn't been home for a long time, take the time to go home, go back to the house to eat with his wife and children, and then take a bath and sleep beautifully, when he woke up, just walked out of the door, he saw Cheng Qingyun respectfully standing outside the door waiting.

As soon as he saw Li Hao come out, Cheng Qingyun hurriedly saluted: "Meet the teacher." ”

Seeing this, Li Hao was surprised and asked, "Hey, why are you here?" ”

Since the summer resort in Lantian was built, Li Hao rebuilt the school next to the summer resort, and now the students and all the people in the scientific research room have moved there, Cheng Chuliang is a scientific madman, in order to do scientific research, he lives in the scientific research room all the year round, and he has not been home for two years, he came to see himself this time, there must be something.

"Teacher, didn't you mention the generator, I made it." Cheng Qingyun forcibly suppressed his excitement, but it didn't seem to be useful, his face was full of smiles.

"Seriously!" Li Hao was also very surprised when he heard this, and hurriedly asked, "Where is it?" ”

"It's in the school's research room." Cheng Qingyun said, "That thing...... Can't move. ”

"Let's go and have a look." Li Hao hurriedly pulled Cheng Qingyun out and asked people to prepare horses as he ran.

Li Hao and Cheng Qingyun rushed all the way to Lantian Shanghe Village, and built a school across the river in the south of the summer resort, and the scale of the school is not small, because now the students in the school have reached more than 1,800 people, more than 30 teachers, and more than 4,000 students have graduated in these years.

Li Hao and Cheng Qingyun came to the physics research room, there were four researchers in the research room doing research work, Li Hao saw a guy fiddling with a big machine at first sight, he was surprised, he felt that this machine was not simple, without waiting for him to ask, Cheng Qingyun explained: "I and others have been studying the steam engine you said for the past two years, although it is currently roughly formed, but it has not been completed, so I did not report to you." ”

"Good, good, well done, keep up the good work!" Li Hao was very excited, he came to see the generator, but he didn't expect to see the steam engine, although the steam engine has not yet been completed, but Li Hao believes that it is only a matter of time, the steam engine, an epoch-making thing, is a great invention than the generator.

Li Haoqiang pressed his excitement, Cheng Qingyun and other scientific researchers took Li Hao to the middle of the scientific research room, only to see a huge pillar standing on the ground, the pillar is more than one person high, all made of steel, the shape is very complicated, Li Hao asked: "This is the generator?" ”

"Yes." Cheng Qingyun nodded and glanced at the other scientific researchers, who hurriedly started wiring.

In this era, there is no rubber, their wires are all bare wires, fortunately, all the wires are straight, not touching anything else, there will not be much danger, the wire is connected to a huge bulb, this bulb is also developed by them, it is tungsten filament, but the tungsten filament is a bit thick, it needs a large current to light, in fact, in this era, the biggest difficulty of the bulb is not the filament, but the air extraction, there is no air in the bulb, the most primitive bulb is a vacuum, Later, argon was filled into the bulb, argon is relatively stable, non-combustible, and does not support combustion, which can make the internal air pressure of the bulb similar to the air pressure, so that the bulb is not easy to burst.

Cheng Qingyun and their scientific research laboratory have already researched all kinds of things that are beyond this era, and they have the ability to extract the air in the light bulb, but ...... When pumping, the bulbs are prone to breaking, so the bulbs here are precious.

After connecting the wires, Cheng Qingyun introduced: "Teacher, when you built the school, let the school cross this river, and said that this river is of great use, I didn't understand at first, but now I finally understand, my generator is powered by the water of this river, but it took a lot of work to build this dam, and I only need to open the sluice gate later, and the water flow will drive the generator, and the generator will start to run to generate electricity, which can light up this bulb." ”

"Please start your show." Li Hao spread his hands with a smile, he was really looking forward to it, although this generator is a little small and a little simple, but this is only a prototype, as long as this generator is successful, the improvement work in the future will be simple.

"Yes!" Cheng Qingyun said in a loud voice, "Open the sluice!" ”

The two researchers immediately began to push the winch shaft, and then they heard the sound of the generator whining and turning, the noise was quite loud, there was no way, the current process was not perfect enough, and noise was inevitable.

With the opening of the sluice, the generator is turning faster and faster, and the huge bulb is getting brighter and brighter, the filament is slightly red at the beginning to the end of the fiery dazzling light, like a small sun, the temperature of the whole room seems to have risen, no way, this bulb is too big, the filament is thick, the power is naturally high, and it is precisely because of the thickness of the filament that it can withstand the strong current provided by a generator, but Li Hao can feel that the bulb is overloaded, and the filament is estimated to not last long.

Sure enough, after a few minutes, the bulb suddenly emitted a burst of intense light, and then instantly dimmed, the filament fused, and everyone's eyes were used to high-brightness lights, and suddenly there was no light, even if there was some sunlight in the room, they felt that it was dark in front of them.

"Well, it worked." Li Hao smiled and said, "And it's alternating current, Cheng Qingyun, you really didn't disappoint your teacher." ”

"It's all cultivated by teachers." Cheng Qingyun saluted excitedly, for 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, increase its power, at the same time, the scientific research on power storage will also be carried out, energy storage technology is not so easy, you must use all the knowledge you have learned, if you don't understand something, go directly to Chang'an to ask me."

"Yes, Teacher."

Li Hao continued: "This wire, bare wire is too dangerous, I know that there is a thing, called rubber, is a very soft insulator, can be used to wrap wires, I will order people to build rubber factories and wire drawing factories in Liu, produce rubber-wrapped wires, and then specially transport them to you for research, if you can also study the steam engine successfully, I will invest in the construction of a small steam engine power plant, first take our school as a test point for electrification, our school, will be the first place in the world to use electricity!" ”

"Thank you, Lord Wang!" Cheng Qingyun looked at Li Hao excitedly, he could almost imagine that a few years later, the entire school would be lit up everywhere even at night, what a beautiful picture it was.

Li Hao turned his head to look at the steam engine, but also fell into reverie with a smile on his face, the emergence of the steam engine and electricity, the change of the world is the greatest, this will be the two deepest footprints of scientific and technological progress, it is these two things, in the industrial revolution, so that European countries by leaps and bounds, far beyond China in decades, and then there is a tragic history of China.

However, now that Li Hao is here, history will be rewritten, as long as the steam engine can be successfully manufactured, Datang will enter the era of industrial revolution a thousand years ahead of history, and the already powerful Datang will undoubtedly become the hegemon of the world.
