In his previous life, Chen Feng was reviled by the whole city as a "traitor who killed his teammates" and died in despair. Reborn 48 hours before the end of the world, he no longer defended himself and directly showed the Savior Medal - the ultimate honor that can only be obtained by those who truly hold the last line of defense. The live broadcast on the entire network exploded, and the hatred and doubts collapsed instantly. But the real enemy is sneering in the dark: medals can be forged, but people will not believe them easily. Su Wanqing returned to the front line with antibody research, Zhao Tiezhu risked his life to send a list of traitors, and inside the base, the gentle Han Ya was quietly releasing mutated zombies. Chen Feng must rebuild trust in the countdown, lead a group of people who once hated him, and kill a more terrifying apocalypse.
