Fang Nan, who transmigrated into the world of *Highschool of the Dead*, received a five-minute warning of a zombie crisis the moment he opened his eyes. Fortunately, he was bound to a super-powerful enhancement system, which comprehensively enhanced his stamina and swordsmanship. He broke out of the dormitory, slayed the first zombie, unlocked achievement rewards, and used the system's power to become invincible among the hordes of zombies. Along the way, he encountered Saya Takagi and Saeko Busujima, and their team-up survival journey officially began.
