Three days before Yang Kai was reborn and returned to the apocalypse, the first thing he did was not to stock up on cans, but to mortgage all his wealth and frantically buy a "waste" called "Inert Crystal Catalyst." The entire Internet mocked him as a "doomsday delusional patient."
It wasn't until the blood moon came and zombies were rampant that everyone discovered in horror:
The "scrap" he bought is the core of activating super weapons!
The "crazy post" he posted was a secret letter to recruit future strong men!
The "abandoned mine" he seized was the only prototype of an S-class shelter!
