Médecins Sans Frontières Lin Wanzhao was reborn three months before the outbreak of the apocalypse. Relying on the memory of dying from a zombie attack in his previous life, he used professional medical skills and the awareness to stock up in advance to transform the basement of the community into a safe base, and contacted old acquaintances to form a team of survivors. After the apocalypse broke out, she used her medical knowledge to save the injured and stockpiled goods to maintain the team's survival. She successively fought against threats such as zombie waves and gangs, gradually expanded her power and established a large security base, becoming the leader of the survivors. In the process, he and underground boxer Shen Qingzhu went from being wary of each other to fighting side by side, developing a relationship of protecting each other, and eventually led the team to the dawn of the post-apocalyptic world.
