Wear easily, no CP, no competition
Zombies have empty brains, and most zombies are stupid, but they can still cause infection if bitten or scratched by them. There are crystal nuclei in the brains of mutant beasts. These crystal nuclei are divided into three levels: Level 1, Level 2, and Level 3, with Level 1 being the weakest. This kind of crystal core can not only repair the injuries caused by mutant beasts, but also has a high chance of eliminating zombie viruses.
