I'm in the Gwen Spider universe, disguised as Peter Parker.
Not only did he fail to become Spider-Man, but he also received the script of being sacrificed... Peter was in a panic.
Fortunately, the sacrifice system has been awakened. By sacrificing items related to Marvel characters, you can gain points to strengthen yourself.
Radioactive spider remains, Mark I, Black Widow's tight leather suit, heart-shaped grass, Chitauri spaceship wreckage, Asgardian warrior armor...
Sacrifice, sacrifice, I'll sacrifice them all!

You start out surviving in the Big Apple, but end up becoming one of the ancestors.
