I Am the Barbarian King of the Apocalypse

The apocalypse arrived, and most of humanity mutated into zombies. The creatures that survived the transformation were even more terrifying than the undead. Zhang Fan survived in the apocalypse for two years, then suddenly found himself reborn on the very day it began. After a great deal of effort, he gained an ability with tremendous potential for growth. 【Ability acquired: Barbarian King. Active Skill 1: For five seconds after activation, ignore all damage. Passive: Double physical attributes, with the multiplier equal to your level.】 【Barbarian King: Level 1 (1/10). Current physical attribute multiplier: 1】 【Note: The active skill can only be used once per day and resets at 00:00. Unused ability uses do not accumulate.】 “With an ability this powerful, if I stay a little more cautious, I should... be able to survive a little longer...” P.S. Story tags: calm, cautious, not a self-sacrificing do-gooder, self-interested, logical, highly plausible, high-IQ, not a simp, not an idiot.
