Technology and materials are limited, Zhong Yuxiu studied for several days before finding some ideas; Don't use lead, cadmium and other toxic metals, the use of lithium metal successfully made a piece of lithium battery, can be recharged and used repeatedly, only the initial production technology is lacking, repeated charging after five times of explosion.

This means that lithium batteries are not stable, and she spent a lot of time researching them; Finally, after half a month, the lithium battery that will not explode was developed, and then the lithium battery was improved to make a lithium battery chip, and the problem came again, today's computer is simple, and the operation is not good, how can the system programming be formulated into the chip?

Zhong Yuxiu's brain hurts, and if the computer can't work, she can only use the light brain; Her light brain can still be used, and the input program is also possible, but what about the follow-up?

One lie has to be fulfilled with many lies, and she doesn't want to do that.

The only way out is to contact the boss of the black market to see if you can get a desktop computer from him; He has a wide network of contacts and has been doing black market business all year round, so Zhong Yuxiu took the time to go there.

"This comrade, meet again, what are you going to do this time?" Boss Fang was full of smiles, and the whole person showed a gentle and harmless attitude.

Zhong Yuxiu's vigilance has not disappeared, "Boss Fang is a celebrity in the black market in Shangjing City, but can he get anything?" ”

"It's natural, you can eat and wear whatever you want." Big talk.

"Where's the computer?"

Boss Fang seemed to be beaten with a stick, and his smile stiffened on his face, "Computer? ”

"Yes, computers, old and new."

"How do you know there's such a thing as a computer? I've only seen that thing twice, but it's not popular now, and it's bulky, so it's not convenient to use at all. Boss Fang's eyes narrowed slightly, and he had to re-examine the lesbian in front of him, and his tone was slow, "The computer is not easy to handle!" ”

Zhong Yuxiu's starry eyes moved lightly, "The old ones are okay, as long as there are them." ”

"Comrade is capable!" Boss Fang sighed lightly, what a capable person! There are ways to repair bad computers, "There are really bad ones, you want them, take fifty yuan; I definitely didn't overcharge you, after all, it's bad, it's your ability to cultivate, and I won't take it over if I can't fix it. ”

"Okay, when can I pick up the goods?"

Boss Fang's eyes paused slightly, and when he saw that she was determined, he said, "You wait a while, I'll ask someone to move you over." ”

"Cheng, I'm tired."

Fang Lao Dalian said politely, turned his head to the inner room and shouted: "Go to Lao Wu's house and move the broken computer over, be careful, and move lightly." ”

"Okay, boss."

The person in the inner room responded, walked out quickly, and hurried towards Zhong Yuxiu.

"Sit, I don't know who the comrade's surname is." Boss Fang pointed casually, "The people who follow me are all big and coarse, and the stools are dirty, don't mind." ”

Zhong Yuxiu shook his head and sat down opposite him, "There are really a lot of people under Boss Fang. ”

"It's all petty, it's not worth it." Boss Fang's words were relaxed and casual, "Comrade hasn't said your name and surname yet, is it because he looks down on someone in my room?" ”

"Boss Fang is serious, I'm just a nobody, I don't dare to stain Boss Fang's ears."

Boss Fang was stunned for a moment, and suddenly laughed, "Cultural people, cultural people, you cultural people are different; It's better to talk than us, okay, I don't force it if you don't say it, I hope we will have the opportunity to cooperate in the future. ”

If you cooperate more, you will naturally know the details.

"Boss Fang is a cheerful person, and there will be more opportunities for cooperation in the future." It's nice to talk to smart people.

"Comrades are also cheerful people, and we have a very pleasant cooperation on both occasions."

Boss Fang didn't insist on knowing her name and surname, nor did he try to find out; The two are somewhat similar in their behavior, so the more they talk, the more they surrender, and when the people below moved the computer back, Boss Fang had regrets and had to speak.

"When the goods are delivered, you inspect the goods; This computer is obsolete, and my buddy will not repair it after getting it back. ”

"You don't have to look at it, as long as you have a lot of parts." Zhong Yuxiu gave the money quickly, "The computer is too large, and I have to trouble the boss to find someone to help me move outside." ”

The boss nodded in response, and shouted to the person who moved the things to move out.

Zhong Yuxiu led people into a ventilated alley on all sides, and the optical fiber was dark, "Just put it here, thank you." ”

"Okay, can you get it?" When a young man saw her little arms and legs, he couldn't help but ask.

"It's okay, someone can help." One man gives a dollar and sends the man away; After half a cup of tea, the mental power did not sense people, so he put the computer in the storage ring and took it away, and took it out and put it in the bedroom when he got home.

Zhong Yuxiu checked the amount of steel left, polished a set of special repair tools with mental power, and left it alone if he threw it to the dog; She should go to class, Dog Dan is a housekeeping robot, and she is also good at repairing electrical appliances at home. In Interstellar, housekeeping robots are the modern equivalent of housekeepers; Because they run on chips, they will have as much knowledge as there is in the chip, and they are more versatile than housekeepers.

An old computer like this is not difficult for dogs.

But in just two days, the dog egg was repaired; It's no problem to boot up.,It's inevitable to have a little card.,It's been used for a long time.,It's still an extremely low memory thing.。

After a few days of tinkering on the computer, I programmed a simple system program, and transferred it to the chip to become a chip with a few simple instructions.

The chip has been researched, although it is very simple, but it can be handled; For the convenience of the future, she has written a set of programs for scientific research knowledge and entered the chip for the dog.

Then she researched a sensor and installed it on the newly made robot, this time she did not make a housekeeping robot, but made a half-human-tall small robot, with a hollow stomach that can hold things, walk on two legs, have no speech function, and have the ability to sense.

After I tried it after I did it, the little robot had limited stomach space and could only hold books, a small amount of clothes, meals, etc.

The key is that the battery of the small robot is rechargeable, and it can charge the robot by itself when it is out of power; She replaced the battery of the dog egg with a rechargeable type, but the battery capacity of the dog egg is larger, and it can be used for a week if it is not greatly improved. Small robots will not work, two days at most.

When she looked up, it was already dawn outside, and she hadn't slept all night; The mental head is not good, the small stomach hurts, and the mind is a little chaotic.

"Dog, breakfast."

"Here we are, master." Dogan came with a tray and placed it in front of her, "Master, it's half past seven in the morning, and you still have an hour to attend the first class of the day; Please hurry up, you haven't washed yet. ”

Zhong Yuxiu replied: "I know, fetch me water to wash my face." ”

"Yes, master."

After breakfast, the tray was pushed; Goudan brought hot water for her to wash her face and brush her teeth, Zhong Yuxiu took the textbooks for the four classes in the morning, and explained when she left.

"Make a few more dishes today, and some guests will come over at noon; Cook two more good dishes and warm them in the pan. ”

"The dog egg has been written down, the owner should pay attention to safety on the road, you are the owner of the dog egg, and the dog egg will be destroyed without you."

Zhong Yuxiu's feet on the threshold paused for a moment, and left expressionlessly.
