The apocalypse strikes without warning, and zombies surround the city. Chu Xiao, a courier, accidentally activates a battle vehicle upgrade system and continuously transforms his battered three-wheeled delivery vehicle into a mobile fortress. Along the way, he gathers supplies and rescues survivors, forming a five-person team with Yi Renmeng, Liu Yiyi, Ran Ting, and Si Meng. Caught between waves of zombies and powerful enemies, they continue to evolve, ultimately taking control of an apocalyptic battle vehicle and embarking on a path to rise from the bottom and become a god.
