In the parallel world Blue Star, the apocalypse broke out, and construction site worker Jiang Wu accidentally activated the "Happy Worker Beating System." Although the system is not powerful, it can be exchanged for key props such as antidote potions and gene evolution substrates. The apocalypse is coming, and zombies and mutated creatures are rampant. Jiang Wu relies on system supplies and his own perseverance to hoard food and establish a safe base to protect his paralyzed sister Su Ziyu. During this period, he met and fell in love with Chairman Bai Feiming, recruited loyal nanny Wang Xi, faced ordinary zombies and agile and powerful evolved zombies, and fought giant mutant creatures. Jiang Wu completed strange tasks in the system to earn points while strengthening his own strength, with the goal of redeeming the panacea.
