Wang Weiguo is reborn in 1952 and awakens the Practice Makes Perfect System. Chopping vegetables hones his knife skills to those of a master chef, swinging a hammer turns him into a Grade Eight smith, and even beating up scoundrels earns him master-level fighting skills!
When Yi Zhonghai shows up with an enamel mug, trying to guilt-trip him with moral high ground, Wang points a homemade sniper rifle at his forehead and uses him to test the wind. When Jia Zhangshi steals half a catty of his refined flour, Wang uses nuclear submarine welding techniques to seal up the rat hole she crawled through.
As Wang goes from an invisible nobody at the steel mill to the chief designer of a great national project, the scoundrels of the courtyard kneel and beg for mercy: “Please, stop practicing your skills!” Little do they know, he has already brought his circle of beauties and slapped the blueprints for an atomic bomb onto a leader’s desk. “This time, we’ll stand atop the Blue Star!”
