Zhao Ting, who heard the voice, walked out of the door and saw the person Li Guocheng was carrying in her hand, her face changed, with her understanding of Li Guocheng, she would never take the initiative to bully people.

"What's going on?"

"I'll give you a big gift", Li Guocheng repeated.

As he spoke, he grabbed his hair with his other hand and exposed Hu Tianqi's face.

"Hu Tianqi! How is he in your hands? ”

"Let's talk about it when we enter the house", Li Guocheng walked to the door of the house with Hu Tianqi in his hand, and when he passed by Zhao Ting, he slapped her lightly on the buttocks covertly, in exchange for the other party's coquettishness.

Li Guocheng threw Hu Tianqi on the ground, took out 56 and a half from behind him, and handed it to Zhao Ting.

"You're not hurt, are you?" After the three of them sat down, Zhao Ting asked about Li Guocheng's physical condition with concern.

"Oops" Li Guocheng held his head and fell to Zhao Ting, she saw through it, pushed it up with both hands, and then gently kicked Li Guocheng's calf with his foot, and glanced at Aunt Liu from the corner of his eye, full of warning.

Li Guocheng was cheeky, smiled, and briefly recounted what had just happened.

"He locked on me with a gun, but he didn't shoot it, probably because he was afraid that the shooting would attract the police or patrols, so he deliberately climbed on the roof to make it easier for me to find out, so as to lure me into pursuit. And then he ambushed at the mouth of the alley and attacked, if it wasn't for my super strong perception, ordinary people might have been hit."

"The timing of the sneak attack is very ingenious, and at the mouth of the alley, people are in a hurry to go out or probe to observe the whereabouts of the other party, and will not pay attention to the corner of the alley in front of them, which is worthy of being an enemy."

"I didn't expect him to be lurking in the rolling mill for more than 20 years, and he has never been married, the information shows that his family died in the war, it is estimated that he was an impostor, we are investigating, it is estimated that it is difficult, the society was very chaotic at that time, and there is no evidence", Zhao Ting explained.

During the chat, Li Guocheng, who had been paying attention to Hu Tianqi, got up and walked to Hu Tianqi's side, squatted down, and pointed a knife at the main artery. From getting up to making a move, it was very sudden, Zhao Ting was thoughtful, and Aunt Liu was full of consternation.

"This kid has just woken up and is pretending to be dead, since he wants to pretend to be dead so much, I'll help him", Li Guocheng explained.

"That's what you learned?" , Zhao Ting gestured with her hand to chop.

"Don't forget, I'm a doctor, and although I don't have a license, I don't have shoes yet."

Such a turn of events is relatively novel for people in this era, Zhao Ting was happy, and Aunt Liu was at a loss.

Zhao Ting noticed Aunt Liu's expression and explained, "Guocheng means that he is a barefoot doctor."

Aunt Liu reacted and scolded with a smile: "You stinky boy."

At this time, the car also arrived, and Li Guocheng helped carry Hu Tianqi and threw it at the foot of the back seat.

"Pay attention to this kid on the road", Li Guocheng knew that he was not qualified to follow now.

"Go back, it's estimated that you will have to interrogate and investigate again in the next few days, and you may not be able to come back at night", Zhao Ting asked before getting into the car.

"Then I'll leave the door for you", Li Guocheng saw Zhao Ting's embarrassed expression, and hurriedly said: "Just kidding, then I'll come to you next weekend."

"Ride slowly on the road", Zhao Ting reminded her, and the car drove away.

I got home without incident, pulled out a semiconductor-related book from the bookcase, and read it. Behind Li Guocheng, the bookshelf is already full of books, mainly physics, semiconductors, and mechanical books, as well as some beautifully painted comic books.

Of course, before each time he goes, he will carefully put on makeup to avoid being recognized in the future, and with the assistance of telekinesis, he will change several key positions and paint his face a little gray, even if an acquaintance can't recognize it at a glance.

In order to facilitate the purchase of 'waste products', I got acquainted with the boss half a year ago, and invited the old man to drink. The old man was quite vigilant at first, and when Li Guocheng bought some old books from the technical school every time he went, he said that the technical school here was the palace in his mind, so the old man let down his guard, and if he drank too much, he would use the palace to squeeze Li Guocheng.

The old man was also righteous, and the books that came out of this technical school were left for Li Guocheng to choose.

The old man did not expect that in recent months, more and more books have come out of the technical school, and occasionally he will receive some strange objects, which the old man has purchased according to scrap iron.

There are a few things that are placed on the test bench in the secret realm, and by the way, the test bench was also exchanged from this acquisition station.

A few days ago, Li Guocheng felt that the old man should have collected a lot of things, and then he asked for leave to go to the acquisition station, but he didn't expect to give Li Guocheng a big surprise, and he actually found a large open wooden box in the corner, which was gray-black powder, which was very similar to what he saw in the hometown laboratory.

"Uncle, what is this?"

"Hey, when a few students were pushing a cart to sell scrap, they said it was a good thing, I thought it was coal ash at first glance, and rubbed it with my hands, damn it, I don't know what it is, so I didn't accept it, a few students dropped their things and left, I was about to wait for my son to come over and help lose it."

Li Guocheng didn't dare to say anything, picked out more than a dozen books, and when he left, he casually said that he would help throw them away, the old man was very happy, and even said that he would leave something good for Li Guocheng next time.

When I went out and threw myself into a secret place in a no-man's corner, I found a description in a semiconductor book when I got home, and I was sure that it was silicon powder.

Now my main job is to learn semiconductor knowledge, and I went to college with a bachelor's and master's degree in electronic automation, and I know how to use chips, but I can't make chips. It seems that the undergraduate "Fundamentals of Electronic Technology" or "University Physics" explains the characteristics and structural principles of transistors, but how to make them is still confused.

Now I only have a copy of "Semiconductor Physics" co-authored by Huang Kun and Xie Xide, and another copy is in Russian, and I only noticed it when I saw the picture on the cover, a very strange physical experiment, and I opened it and saw the familiar transistor structure diagram.

Some of the other magazines about semiconductors have no practical meaning and are news-like stuff.

Do you have to rely on these two books to make chips, I originally thought that Wudaokou would have a lot of relevant information in this technical school, but I didn't expect to buy only two books. It seems that I will have to go to this technical school in the future.

Li Guocheng closed "Semiconductor Physics" and learned a little about how transistors are made, and his next main job was to learn Russian. At this stage, I don't dare to find a Russian translator. Well, Yiduo didn't press down, so he had to comfort himself.

Entering the secret realm, looking at the three crucibles on the test bench and the only small cube, just like the size of the lead word in the printing factory, 3*3mm, through reading "Semiconductor Physics", I know that this thing is called silicon seed crystal, which is the main raw material for drawing silicon single crystal.

This small cube was bought with the crucible, the value that the old man didn't know, Li Guocheng was also confused, and he spent a total of 3 yuan to accept it by feeling, and for this, the two of them bargained for a long time with a white face. In principle, the acquisition station has the type and price of the purchase, but now is an extraordinary period, the management is relatively chaotic, and the old man is also a bold man, who dares to collect anything.

Put the precious silicon seed crystals into the brocade box and go out of the secret realm to sleep. Tomorrow I will take a leave of absence and go to the acquisition station again, hoping to find materials for studying Russian.
