In fact, Lin Qi and Zhang Dahai's cooperation was relatively smooth. However, in order to determine who the dominant power was in control, Lin Qi had to hit Zhang Dahai.

The knocking is also for Zhang Dahai's goodness. Otherwise, Zhang Dahai will be too inflated and cannot recognize the situation, and sooner or later he will be abandoned by Lin Qi.

And if Zhang Dahai can truly realize that he is a chess piece that Lin Qi is playing, then he will benefit for the rest of his life!

After returning from the company, after returning home.

Lin Qi hung a wooden sign outside his home, saying that he would go out for inspiration and return in three days.

In fact, in the past few days, Lin Qi is preparing to go back to the 21st century.

Lin Qi took a "return permit" processed by Xinhua News Agency's Hong Kong branch and returned to Shenzhen on the other side from the Zhongying Street Port on this side of Hong Kong.

He is preparing to open the door of traveling in Shenzhen...

...

"The door of time travel... opens! expands!..."

The opening of the crossing door is not without conditions.

In fact, it takes about one month of energy to open for 10 minutes. When the portal is completely opened, the gap is large enough that people can pass through.

When the portal is not opened, there are only a small gap to observe the opposite side.

Lin Qi only knew that when he did not use the time travel gate, it was probably charging with enough energy to satisfy the use of the next time travel.

As for whether the energy used for the crossing gate is light energy, electromagnetic waves, or something else, Lin Qi knows nothing.

Of course, Lin Qi is not a scientific researcher, so it doesn’t matter if he doesn’t understand the principle, as long as he masters the method of use.

In essence, Lin Qi is a pragmatist - a white cat and a black cat. A good cat who can catch mice is a good cat.

...

Before the portal opened, Lin Qi carefully observed the opposite side until he found that there was neither a person nor a camera on the opposite side, and there were old buildings nearby.

At this time, Lin Qi began to take steps and got into the game...

Take one step and you will be in the end!

The next moment, Lin Qi had returned to the world of the 21st century.

When he came back, Lin Qi was empty-handed and took nothing except his ID card and 1,000 yuan in cash. He was in Shenzhen, thousands of miles away from his hometown, and he was unfamiliar with his place.

However, this doesn't matter. Lin Qi thought about it and spent 499 yuan to buy a mobile phone with an outdated configuration.

After you get the phone.

The next moment, Lin Qi found Starbucks on the street and ordered a cup of coffee, and then he felt at ease to hop on the Internet in the coffee shop.

Although the phone does not have a card installed, it is still OK to use the free hotspot signal as a tablet that can access the Internet.

After downloading various apps, Lin Qi opened QQ and sent a message to a friend with the online name "The God of Electronic Fever": "I want to buy some electronic components to play with, but I don't know, what are some good suggestions?"

"Playing with electronics? This range is too wide. Most of the things that fly from the sky, climb on the ground, play in your hands, and put on electric items at home are related to electronics." The God of Electronic Fever replied quickly, "What do you want to play?"

"I don't know, I don't know very well for the time being. First, play some electronic watches, calculators, etc. If you understand, then play with the handheld machine. I want to make a toy that can play Tetris by myself." Lin Qi said.

"It's simple, I can teach you." said the God of Electronic Fever, "You can download some tutorials, books, and videos at this website. Starting from scratch, use the simplest electronic components, make circuit diagrams by yourself, solder circuit boards by yourself, and write programs by yourself. I tell you that playing hardware is just an introduction. When you play to a certain level, you can hand-solder CPU by yourself."

"This, brother. After getting started, I have to buy components. I don't understand!" Lin Qi said humbly.

"It's troublesome not to understand at all. It takes a long time to learn... When you get stronger, your hair will probably be bald!" said the God of Electronic Fever with a headache, "You are there, I'll send you something to try to play with. If you're enjoyable, you can buy some components yourself."

"I'm in Shenzhen..." Lin Qi said.

"Ah? That's great. I've always worked in Shenzhen." said the God of Electronic Fever, "Go to this address to find me..."

Later, Lin Qi humbly found the stronghold of the God of Electronic Fever...a warehouse of an electronic component company. This netizen was originally engaged in the electronic component business. Because he is an enthusiast of various hardware and likes to design and manufacture various hardware and toys by himself, he also likes to make friends with others and often make some strange electronic toys to give them to others, so he is called Doctor Cat by some online friends.

Lin Qi felt that this friend was very magical, and now he needed such a friend's help.

After coming to the warehouse of the home of the God of Electronic Fever, the God of Fever gave orders to his employees. After assigning some tasks, he took Lin Qi to his laboratory with great enthusiasm.

"Look, this is a wearable phone I designed myself. The size of the phone is about the same as a watch, and it is also the shape of a watch... You can insert a phone card, and 2g communication is fine. There are touch screen phones all over the street. If you wear this thing on your hand and make a phone call, it will definitely attract attention." The God of Fever took out the watch and said, "I've come to the humble house all the way, and there are no gifts, I'll give it to you!"

Lin Qi took this thing with a lot of laughter and cry. This watch-shaped mobile phone is useless! You can’t install apps online, and you can’t even krypton money on mobile games.

Despite this, Lin Qi still accepted the gift.

After seeing Lin Qi accepting the gift, the electronic fever friend showed a satisfied smile. He seemed to be an unsuccessful artist, and his greatest ambition was that his works were recognized.

Friends of electronic fever are named Liu Rui. They have been exposed to various electronic components since childhood.

When he was a child, his father worked in a TV factory. Later, his father opened an OEM factory, starting from OEM manufacturing MP3 to OEM computers, mobile phones, and tablets, which gave him more opportunities to play with hardware.

Through years of hard work, he has become a hardware master and has many lost skills. For example, he has written a similar program of "Super Mario" under the limitation of memory with only 64k or even smaller memory.

This kind of skill that tests programmers' level was probably only before the 1980s, with small memory calculated in bytes. At that time, 1kb was already a very large capacity. Under those harsh conditions, programmers used assembly to write code, which was completely different from current programmers.

Of course, it is one thing that Liu Rui has a high technical level, but his hobbies are too biased. For example, he designed and made a game machine similar to a red and white machine. All the components including CPU were soldered by himself, and the source code was written by himself, but what's the point?

After all, it is now the 21st century... Those inventions and technologies will not have market prospects unless they go back to decades.

After Lin Qi visited his laboratory in person, Liu Rui wanted to accept Lin Qi as his disciple and teach him all his lifelong knowledge and experience in electronics.

However, Liu Rui found that Lin Qi's foundation was too poor. If you start learning from scratch, it would take at least a few years before you could get started.

Therefore, Liu Rui recommended a lot of information, from easy to difficult, to sort it out for Lin Qi. In addition, he sent a bunch of introductory electronic components, which can assemble function calculators, handheld game consoles, home game consoles, etc.

"Learning electronic knowledge is one aspect, and the more important thing is to do it..." Liu Rui said, "It doesn't matter if the foundation is poor, the key is love! As long as you keep this hobby and never give up on research, you will definitely succeed in your studies in the future!"

The two bid farewell to each other.

Before leaving, Liu Rui said, "If you don't understand, I can go online at any time!"
Chapter completed!
