Due to limited technology and materials, Zhong Yuxiu studied for several days before she found some ideas. Instead of using toxic metals such as lead and cadmium, she successfully made a lithium battery using lithium metal. The battery can be recharged and used repeatedly. The only problem was that the initial production technology was flawed, and it exploded after being charged five times.
This meant that lithium batteries were not stable, so she spent a lot of time researching. After half a month, she finally developed a lithium battery that would not explode. She then improved the lithium battery and made it into a lithium battery chip. But then the problem arose. Today's computers are simple and cannot run well. How can she program the system into the chip?
Zhong Yuxiu had a headache and since her computer didn't work, she had to use an optical computer; her optical computer was still usable and she could input programs, but what about the follow-up?
One lie requires many lies to cover it up, and she doesn't want to do that.
The only way out was to contact the boss of the black market and see if she could get a desktop computer from him; he had a wide network of contacts and had been doing black market business for many years, so Zhong Yuxiu took the time to visit him.
"Comrade, we meet again. What are you going to give me this time?" Boss Fang smiled broadly, appearing gentle and harmless.
Zhong Yuxiu's vigilance remained undimmed. "Boss Fang is a famous figure in the Shangjing black market, but can he get anything?"
"This is nature. We have everything we want, including food, clothing and daily necessities."
"Where's the computer?"
Boss Fang looked as if he had been hit by a club, his smile frozen on his face. "Computer?"
"Yes, computers, new or old, will do."
"How did you know about computers? I've only seen them twice. They're not very popular these days, and they're bulky and inconvenient to use." Boss Fang narrowed his eyes slightly, having to reassess the woman in front of him. He slowed down his tone, "Computers are not easy to use!"
Zhong Yuxiu's starry eyes moved slightly, "Old or broken ones are fine, as long as they are available."
"Comrade, you're really capable!" Boss Fang sighed softly. What a capable person! There's a way to fix a broken computer. "There really is a broken one. If you want it, take it for fifty yuan. I'm definitely not charging you too much. After all, it's broken. If you can fix it, that's your ability. If you can't, I won't take it over."
"Okay, when can I pick it up?"
Boss Fang paused, and seeing that she was determined, he said, "You're lucky. I just got a broken one from a friend these days. Wait a minute, I'll have someone bring it over to you."
"Okay, thank you for your help."
Mr. Fang was too polite to bother with this. He turned around and shouted towards the inner room, "Go and move the broken computer from Lao Wu's house. Be careful and be gentle when you move it."
"Okay, boss."
The person in the inner room responded, walked out quickly, nodded hurriedly at Zhong Yuxiu and left.
"Sit down. I don't even know your name, comrade." Boss Fang pointed casually. "The people who work with me are all rough guys. Don't mind if the stool is dirty."
Zhong Yuxiu shook her head and sat down opposite him. "Boss Fang has quite a few subordinates."
"They're just small fry, nothing to worry about." Boss Fang said casually, "Comrade, you haven't even mentioned your name yet. Are you looking down on me, Fang?"
"Boss Fang, this is serious. I'm just a nobody. I don't dare to pollute Boss Fang's ears."
Boss Fang was stunned for a moment, then suddenly burst into laughter. "People of culture, people of culture, you people of culture are different; you speak more eloquently than us. Okay, if you don't want to say it, I won't force you. I hope we can have the opportunity to cooperate again in the future."
The more you cooperate, the more you will know the details.
"Boss Fang is a straightforward person. There will be many opportunities for cooperation in the future." It is comfortable to talk to smart people.
"He is also a straightforward person. We had a great time working together twice."
Boss Fang did not force himself to know her name, nor did he try to pry into the subject; the two of them had some similarities in their ways, and so the more they talked, the more they got along. After the people below brought the computers back, Boss Fang felt regretful and had to speak.
"The goods have been delivered, please inspect them. This computer is obsolete. A friend of mine managed to get it back, but he doesn't know how to repair it."
"No need to look, as long as there are enough parts." Zhong Yuxiu paid without hesitation. "The computer is too big, and I'll have to trouble Boss Fang to find someone to help me move it outside."
Boss Fang nodded in agreement and told the people who came to move the things out.
Zhong Yuxiu led the people into an alley with good ventilation on all sides. The optical fiber was dark. "Just put it here. Thank you very much."
"No problem, can you take it away?" A young man asked when he saw her small arms and legs.
"It's okay, someone is here to help." He gave each person one dollar and sent them away. After half a cup of tea, he still couldn't sense anyone with his mental power, so he put the computer into the storage ring and took it away. When he got home, he took it out and put it in the bedroom.
Zhong Yuxiu checked the remaining steel, used her mental energy to forge a set of specialized repair tools, and then handed them to Goudan, leaving them alone. She was supposed to be attending classes, while Goudan, a household robot, was also adept at repairing household appliances. In interstellar space, household robots were the equivalent of modern-day butlers; because they ran on chips, they could absorb whatever knowledge was stored in those chips, making them even more versatile than butlers.
An antique computer like this is no problem for Goudan.
However, Goudan fixed it in just two days; it started up and ran fine, but a little lag was inevitable, as it had been used for a long time and it still had extremely low memory requirements.
After tinkering with the computer for a few days, I programmed a simple system program and transferred it to the chip, which became a chip with a few simple instructions.
The chip was developed, and although it was very simple, it was enough to cope with the problem. For future convenience, she wrote a set of scientific research knowledge programs and recorded them into the chip for Goudan.
Then she researched a sensor and installed it on a new robot. This time she did not make a household robot, but a small robot half the height of a person, with a hollow belly for storing things, walking on two legs, no language function, but with sensing ability.
After I tried it out, I found that the little robot had limited space in its stomach and could only hold books, a small amount of clothes, food, etc.
The key is that the small robot's battery is rechargeable, so if it runs out of power, it can be recharged by the robot's Dharma command. She also replaced Goudan's battery with a rechargeable one, but Goudan's battery has a larger capacity and can last a week on a single charge, assuming it doesn't improve significantly. The small robot can't do that, at most two days.
When she looked up, it was already dawn outside. She hadn't slept all night yet again. She wasn't feeling well, her lower abdomen ached, and her mind was a little fuzzy.
"Goudan, breakfast."
"I'm here, Master." Goudan came over with a tray and placed it in front of her. "Master, it's 7:30 in the morning. You still have an hour before your first class. Please hurry up, you haven't washed up yet."
Zhong Yuxiu nodded and said, "I understand. Bring me some water to wash my face."
"Yes, Master."
After breakfast, she pushed the tray aside; 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 gave them instructions before leaving.
"Make a few more dishes today, as we have guests coming over at noon. Also, make two more good dishes and keep them warm in the pot."
"Goudan has taken note. Master, please be safe on the road. You are Goudan's master. Without you, Goudan will be destroyed."
Zhong Yuxiu paused for a moment as she stepped out of the threshold, then left with an expressionless face.
