Reject the ancient gods from parasitism at the beginning.
No rebirth, no cheating, no systematic doomsday writing.
A red rain has started the apocalypse. Under a series of doomsday catastrophes such as zombies, alien beasts, and cleansing rules, you can only rely on yourself to survive. I originally thought it was a simple zombie apocalypse, but as the apocalypse progressed, I discovered that it was a long-planned conspiracy, just to exterminate mankind. In the face of invincible enemies and human predicament, humanity can only survive step by step if it wants to survive.
In the apocalypse of the Red Wasteland, their only way to survive is to create gods.
