Xiao Ce, a modern chief instructor of the Longyan military training corps, transmigrates into the body of Xiao Laizi, an ancient-era gambling addict, inheriting a mountain of gambling debts and a broken family. Horrified by his predecessor's cruelty in selling his own children, he uses his tactical spatial ring to lead the entire family to turn their lives around. First, he uses military combat techniques to rescue his eldest daughter from being sold, then outsmarts the Black Tiger Gambling House and destroys the debt documents. Next, he uses modern dyes to break the dye industry's monopoly and earn his first fortune. He then builds greenhouses to grow out-of-season fruits and vegetables, helping the entire village become prosperous. Zhou Tong, a wealthy local businessman determined to protect his dominance, repeatedly resorts to sinister schemes, including poisoning seedlings with tung oil, spreading rumors of plant diseases, and hiring assassins to wipe out the family. But Xiao Ce foils every one of his plots.
