In the ruins of a certain city, there lived a human, a man with a robe made of worn cloth. Also true, it's too difficult to mass produce fabric.

?: Ah, here it is! A little bit of machinery can be used.

Half a motorbike? Looks like it's been heavily rusted. If you want to use it, then there is only the engine. As for this metal shell, it must be forged as a tool.

I need to keep digging, if I can't find anything I'll just starve. I wish I had an excavator, but it's just a dream. That's only enough for slave owners. For someone like me, it's equal to being able to look at the sun again. Oh, it reminds me of that day. If I lie down like this, I probably won't have anything to eat today. All because of that damn explosion, without it I would be a completely different person now. It reminds me of my parents' deaths, for a moment a beam of light passed through the shattered glass they had covered for me. But at least I'm still luckier than most people, not everyone can live, let alone ask here.

?: Come on, wake up! aght real back pain. I guess I'll have to buy a blanket.

He continued walking around the ruin, layers of dust still blowing through. The hard breathing through the gas mask was simply overpowered by the hiss of the wind. He only found a little more metal. After he finished picking it up, he took off his cloak, put the scraps in and carried it over his shoulder. He walked step by step in a sandstorm. Perhaps there was no one else in this place but him. If they really wanted to survive, they would have chosen to go east away from the explosion, but he still held on to this inhospitable place. After spending a whole day walking, he stopped at a ruin from a tall building. Inside the broken glass on the floor, he cautiously stepped inside. Just lose focus for a moment, there will be hundreds of guys ready to kill him just to let his best friend survive.

He glanced around to make sure the place was safe. He just slowly spread a large canvas over this place. In this world, a single open wound was enough to make death inevitable.

He gently set the metal bag aside. Choose a sheltered spot and slowly relax your body. He rummaged through his old backpack and pulled from it a book, which was about physics. In a place ravaged by technology, knowledge is like an absolute evil.

?: ah I finally got some rest. I think I'll have to find more books. I should slow down the reading speed.

He closed the book without looking at it difficult to understand, he must have read it a hundred times. But whether the dream was an illusion or not, the pressure of survival forced him to put the book down to check his surroundings and slowly fall asleep.

?: Ah! a great sleep ! How long has it been since I slept like that?

But now maybe just go? He once again took his backpack and left, still holding the heavy bag in his hand. Although the sandstorm has stopped, it is clearly still not easy. He kept walking leaving a trail of footprints that stretched like a straight line. He went to a place that looked like a giant factory. On it was a small grafity line that simply said "market". On the flagpole hangs a black background flag with a red diamond inside. He seemed quite familiar with the place.

"Hello Seimei!" - a man with dark skin, muscular body.

Seimei: Hi Kevin! but Seimei is last name.

Kevin: I'm still not very good at Asian names, am I?

Seimei: Then you'll get used to it.

Kevin: So you have something again today?

Seimei: Oh, some metal stuff. I was going to sell it to the smithy, but there's a small problem.

Kevin: What's the problem bro?

Seimei: Can you remove the "bro", in general I have a copper coil, but the power generators that I know of, they don't need.

Kevin: Dong? Looks like there's a new stall on the east side of the aid zone that buys copper and gunpowder in bulk.

Seimei: Are they going to make bullets?

Kevin: Yeah they said they were going far northeast so they needed to build some ammo just to be safe from the bandits.

Seimei: Ok, goodbye!

Kevin: Yeah bye bro!

Seimei: Can remove "bro"?

Kevin: Haha.. Ok Ok
