On the surface, it is a modern urban "mirror city", but in fact it is a "breeding farm" kept in captivity by "gods" who exist in higher dimensions. 99% Of the residents are "weirds" disguised as humans. The Mirror City is separated from the real world by an invisible barrier. The "God" will open the "Harvest Gate" on the first day of every month, allowing some "weird" creatures to enter the real world to hunt. At the same time, this is also the only chance for humans to escape.
