The apocalypse descends, and the white tiger guards the border alone, holding out against the beast tide for a month, fighting bloody battles until exhausted and dying. Three days after the white tiger's death, the city fell and its people perished. The entire body of city survivors experienced collective rebirth, returning sixty days before the apocalypse. Commoners brought food to feed the tiger, the military mobilized entirely, and everyone shared the single goal of finding the white tiger. The transmigrator Gong Baiwan is reincarnated as a frail albino baby white tiger, awakening the twin systems of devouring evolution and national fortune. The apocalyptic countdown begins, and the military takes the lead in finding the baby tiger. In the past life, the tiger protected all citizens with its flesh and blood; in this present life, the whole country accompanies the tiger to resist the apocalypse together. Ten major cities: Jicheng, Nicheng, Taicheng, Meicheng, Liangcheng, Niancheng, Bancheng, Liancheng, Xicheng, Baicheng.
