1. All things can mutate, monsters rule humans, and with the legacy of technological civilization from thousands of years ago, it has a bit of a cyberpunk and broken world flavor.
2. The protagonist Xu Xiu is dormant in the market, using a brand-new ability system to avoid surveillance and wait for opportunities.
3. The story focuses on the protagonist relying on his brain and ability to develop himself, make companions, and subvert the monster's rule. While striving for a sense of substitution, he does not deliberately suppress the protagonist.
4. Kind reminder: I don't deliberately create scenes of pretense, harem, regret, invincibility, etc. I'm sorry for those who like this kind of stuff."
