"Hello, are you there?" Zhang Bei asked anxiously.
After about three seconds, just as Zhang Bei was about to send another message, the other party replied, "Yes. What can I do for you?"
Zhang Bei was overjoyed. He asked, "How do you want to trade that thing of yours?"
The other party hesitated for a moment and asked, "What do you want this thing for? What do you plan to exchange for it? I only want to exchange it for food."
Zhang Bei heaved a sigh of relief and said, "That's okay. How much food do you want?"
The other party thought for a while and said, "I want three days' worth of food."
Zhang Bei did not agree immediately. After all, food was very hard to come by nowadays. It was better to save as much as possible.
Zhang Bei: "Two days. I'm not the kind of person who takes advantage of others. Food is indeed too scarce. Two days' worth of food is the highest I can afford. If you agree, we can trade. If you don't agree, then forget it. Anyway, I don't really need this thing."
After about a minute, the other party replied that it was a deal. Zhang Bei took out two days' worth of food and placed it aside to confirm the deal. After about ten seconds, the other party's item was also exchanged.
He took a look at it and found that it was a classic old computer console. Its black outer shell had lost a lot of its paint.
Zhang Bei didn't care much about its outer shell. He only cared about the circuit board and wires inside.
He picked up the small knife and removed all the screws, then carefully put them aside.
He opened the back cover of the console to see if there was anything he could use.
Zhang Bei was very happy. Not only were the wires and other things intact, but the circuit board was also intact. He thought that there was definitely hope for this mecha repair.
First, he carefully removed the wires while keeping the interfaces intact. Then, he removed the circuit board and checked the storage cards.
"I wonder if this mecha can install things like these storage cards." Zhang Bei didn't think too much about it. He just put them aside, and picked up the circuit board. This was the most important thing. But when he picked it up, he found that there were many things missing.
The various test points inside were not connected, and there was no silicon material inside.
This was like pouring a bucket of cold water on Zhang Bei. It was so cold that his heart chilled. "How can I repair such a high-tech thing like circuit boards in space?"
Although he was from the engineering department, he had never built a circuit board before. Zhang Bei held the circuit board and looked around, feeling helpless.
After a while, Zhang Bei suddenly thought of something. If he could melt the copper, or connect it directly with the copper wire, would that be enough? Could he consider replacing silicon material with something else?
He looked at the circuit board and thought for a while. He decided to try melting the copper first.
When Zhang Bei connected the wires earlier, he had used fire to burn the wires. After the wires were softened, he connected them together. He should be able to melt copper wires and connect the test points on the circuit board.
He was a doer. He first picked up the flame stick. Because the fire needed this time was indeed larger, he used the thorny brambles that he had cut down previously and piled them together. Then, he lit a fire.
Zhang Bei piled the mecha and some necessary items beside the fire. He would repair it all together. This would save a lot of energy.
He thought for a while. Since he had already lit the fire, he might as well take out the chicken wings and cook them as well. Zhang Bei looked at the bag of chicken wings beside the bed. The chicken wings had thawed and become soft.
He brought over a few packets of instant noodles, took out the seasoning packs and put them in a basin. Instead of calling it a basin, it was more like a slightly larger pot from the kitchen wares that he had picked up earlier.
Zhang Bei washed the chicken wings with water and made a few incisions with a knife to make it easy for the condiments to seep in. Then, he put them in the pot. He put 20 chicken wings in the pot, opened the seasoning packets, and sprinkled them over the chicken wings.
He rubbed the chicken wings hard to let the flavor of the condiment bag seep into the chicken wings, then put the chicken wings aside and waited for them to marinate.
While waiting for the chicken wings, the copper wires were still being burned. Zhang Bei realized that after a certain period of time, the copper wires would only be burned red, but they would not melt.
"Looks like I have to think of other ways. After all, the circuit board needs melted copper wire. This definitely won't do," Zhang Bei scratched his head and thought.
Then, he casually threw the copper wires beside the fire. He suddenly recalled that the connected copper wire was exposed. If there was a leak, it might be dangerous.
Therefore, he cut off a part of the water pipes in the greenhouse, and then cut them into small pieces. He quickly heated the plastic, softened it, and wrapped the exposed copper wire with it.
He heated the pipe pieces one by one. With his quick reflexes, he quickly finished wrapping all the copper wires.
"It's much safer this way. I'll feel much more at ease when I use the mecha to explore in the future, and won't have to worry about electric shock."
"The chicken wings should be marinated." Zhang Bei walked into the tent and looked at the chicken wings scattered all over the table. He breathed in the fragrance and couldn't help but drool.
He chipped a few thorny brambles into skewers, making it easier to spit-roast the chicken wings.
After some thought, he took out a few more ham sausages and skewered them as well. Then, he scored them lightly. This way, it would be easier to roast them.
He then began to insert the chicken wings into the skewers.
Soon, Zhang Bei finished preparing a few skewers of chicken wings and brought them outside to roast beside the fire.
