Pick up garbage in another world and bring it back to build infrastructure in the end times

"Little sister, are you keeping this thing for yourself? Just give me an ordinary optical computer, and take this back."

He took it off directly, but was immediately rejected by Sang Chu:

"Brother, I've set up self-destruct devices on all my optical computers. As soon as they're out of the hands of the certified person and activated by someone else, they'll explode immediately. Everything stored in the optical computer will self-destruct. If the hover car wasn't the only thing that can be stored in the optical computer once it's turned on and used, I wouldn't have put it in the optical computer."

Sang Jingwen was frightened by Sang Chu and dared not make any unnecessary movements.

Xiao Yifei said cheerfully, "A self-destruct device is good. This way, we don't have to worry about other people snatching away the good stuff. Sister, can your self-destruct device be cracked by others?"

Sang Chu shook his head: "No, this was already set during the authentication."

She didn't explain clearly that she was the first certifier of all the hovercrafts, optical computers and space ties, and only she could recycle these things. Once the things were activated by others without going through her, all of them would immediately enter the destruction program.

She suddenly remembered that she hadn't told anyone else about this, so she immediately sent a group message asking them not to let anyone else try it on or give it away as a gift.

Once the self-destruct device is activated, everything will turn to ashes.

"Sister, how about we go to Xinshi and take a look?"

Xiao Yifei spoke cautiously. Sang Jingwen looked at him and asked, "Do you want to go find your parents?"

"Well, although I don't know if they can survive, they are my family after all. I want to go and see them. I have to go find zombies anyway, so why not take the Xinshi route?"

Xinshi is much farther away than Shangjing, but since the hovercraft travels very fast, it may not take long to arrive.

Sang Jingwen: "Little sister?"

"In that case, let's go to Xinshi. Lu Minfeng's parents are also in Xinshi, so we can take a look together."

"Yeah, sister, you are so nice!"

Sang Chu: "Since we are going to Xinshi, we can't continue to be in this off-road vehicle. Sit tight, I will change my form back."

"Uh-huh!!!"

Xiao Yifei nodded excitedly, hugged Sang Jingwen's waist tightly with both hands, and stared at Sang Chu motionlessly.

She just operated the computer and the off-road vehicle instantly turned back into a hover car.

They are also sitting on the soft sofa at this moment.

Xiao Yifei couldn't help but kick it hard. This white and soft sofa like a cloud was so attractive that he couldn't let it go.

"Wow, sister, do you still have this hover car? Can I buy one from you?"

"The hovercars are limited. Sorry."

Xiao Yifei: "That's fine, but if you have any more, be sure to reserve a few for me. I'll keep all the crystal cores for you when you kill zombies later!"

"Okay, I'll remember that!"

"Of course I will. My word is my bond!"

Sang Chu looked at him and couldn't help but smile: "Brother Yi's personality is quite different from my brother's. I never thought that you two would be good friends!"

Xiao Yifei sat up, put his arm around Sang Jingwen's shoulders, and said with a brotherly look:

"Then you don't know how aloof your brother can be. We've been living in the same dormitory for three years. In the first year, he ignored me. I chased after him but got rejected many times!"

Sang Chu smiled and said, "My brother is like this, cold on the outside but warm on the inside. Okay, you two can chat. There should be some food that Lu Minfeng made in the kitchen. If you're hungry, just heat it up. I'm going to take a nap. Call me if you find any zombies."

Sang Jingwen: "Well, go ahead."

Sang Chu took Tu You back to the room and continued to practice using the spirit stone jade.

Xiao Yifei: "Your sister seems to be much easier to get along with than you!"

Sang Jingwen: "Well, Sangsang has always had a good personality, but since we met again after the apocalypse, he has become much calmer than before."

"Hey, it's the end of the world, everyone is growing up. Remember when you and I were killing people and zombies, our hands were shaking like crazy? You had nightmares for days. Growth is a good thing. You don't have to be so worried."

Sang Jingwen sighed helplessly, "I don't have any special abilities, so I can't help her with many things. She even gave me the computer she prepared for herself. After we met again, I just felt like I was holding her back."

"Brother, you're totally wrong to think that. Think about it, how many people can you trust in the apocalypse? Those few I brought here just wanted to kill me. If you hadn't reminded me that I had a trick up my sleeve, you wouldn't even be able to see me now. You can imagine that you have a pretty good brain. Your sister wants to build a base, so why don't you help her check who can be used and who can't? If you observe more, won't you be able to help as well?"

"What do you consider useless?"

Sang Jingwen couldn't help but complain, but who knew that this arrogant guy would lie back on his lap, eating the chestnuts he had peeled, and said slowly: "Since we are here, we should make the best of it. Who knows when this apocalypse will end? We should just live one day at a time. Why think so much?"

"Too."

Maybe he should learn from Xiao Yifei's attitude, not think too much, and just focus on the things at hand.

......

In the room, Sang Chu just stopped practicing. As soon as she opened her eyes, she saw Tu You staring at her with wide eyes: "A Chu, your ability is improving so fast!"

"This spirit jade should be more effective. After I kill the zombies, I will try the crystal core. If the crystal core has the same effect as the spirit jade, I will use the crystal core to practice in the future."

Tuyou shook his head: "How can they be the same? Spirit Jade is much better than Crystal Core. But, do you really want to hunt zombies?"

Sang Chu heard something strange in his words and asked, "Is there a problem?"

Tuyo: "Of course, not every zombie has a crystal core. If you kill all the zombies, what will you do if there are no crystal cores?"

"this....."

Tuyo: "I think you should choose some zombies that look like they've awakened superpowers to kill. That way, you can guarantee you can dig out crystal cores from every one you kill. You can keep the ordinary zombies. Aren't there a lot of bases out there? Once crystal cores become common, you can use them to trade. You have so many supplies on hand, are you worried that no one will use them to buy things from you?"

After hearing this, Sang Chu fell into silence. Although the zombies were isolated outside the high walls, they still posed a serious threat to humans.

If we really keep it as Tuyou said, will it become an uncontrollable existence in the future?

Seeing Sang Chu remained silent, Tuyou continued, "Besides, you can now travel between various time and space. Who knows if any world will develop a cure for zombies? If you kill all the zombies now, what if one day you find a cure for zombies? Wouldn't you feel cruel?"
