Apocalyptic Survival Game: I Rely on Blind Boxes to Unlock Immortality

[A different world + upgrades to fight monsters + multiple female protagonists + decisive killing] In the apocalyptic world, zombies are rampant and alien beasts are raging.

Golden light explodes——[Congratulations on obtaining the master-level passive skill: Yin-Yang Symbiosis Technique] Chen Mu's old face turned red: "System, your... Blind box has something!" While others are still fighting for a few points of life span, Chen Mu has used a blind box to break through the rules of the world, sit on countless goddesses, and start his own path to immortality...
