The Evil God of Desolation Accompanies Me Through the Apocalypse

The good news is that in the apocalypse, the protagonist accidentally gains the favor of the ancient evil god. Bad news, the evil god is now down and out! As an orphan, the protagonist Wang Mingrui barely makes ends meet by doing odd jobs in the dungeon. The former five evil gods have now been eliminated by other evil gods, kicked out of the subspace, and curled up in a dagger to survive for hundreds of years. Two equally miserable souls collide and move forward hand in hand, feeling sympathy for each other? Or are they plotting against each other and deceiving each other?
