In 2099, a zombie apocalypse ravages the globe. Two weeks in, the Federation announces a miraculous airborne vaccine—only for it to fail spectacularly. Betrayed by his ex-girlfriend Xu Feifei and beaten by thugs led by Li Yinhe, Qin Yun flees for his life. At death’s door, he awakens a powerful Survival System. Just as the undead rise again, Qin Yun meets the righteous Su Qingyan. When his betrayers return hunting for supplies, they find a changed man. This time, Qin Yun isn’s a "simp"—he’s their worst nightmare.
