When Su Chen, an SSS-level superpower, piloted a god-killing mecha made from the genes of alien gods, he was the only hope for mankind to fight against the "beyond the wall".
Human beings prefer to stay within high walls. The real threat is not the strange beasts in the wilderness, but the high-dimensional creatures called "gods" behind the "door". Super-powered mechas allow humans to steal the power of gods, and the protagonist's ultimate choice will determine whether human civilization is completely destroyed or sublimated into a new "god."
