Fifty-year-old security guard Chen Fusheng has worked diligently for half his life, only to be spurned by his wealth-despising wife Liu Yuhe and pressured by his son Chen Jiaan for an exorbitant bride price. When he is critically ill, the mother and son even abandon him to collect on a death insurance policy. In his desperate plight, he triggers the Carefree Life System, gaining one hundred thousand in cash and a vigor pill, returning from the dead. Rejecting moral blackmail and unlocking system perks, he becomes confident and strong. After divorcing his ex-wife, by a twist of fate he rescues Su Wanxing, the president of the Su Group who has been drugged. Relying on his skills, Chen Fusheng undergoes a complete transformation, repeatedly slapping faces at class reunions, workplace competitions, and antique markets, kicking off a fantastical counter-attack from a pathetic security guard to a winner in life.
