Zhang Wen, a bottom-level salesman, accidentally activated the Recycling Master system when he was bullied and resigned to join the recycling of second-hand mobile phones. He met Mu Qiuyue, the eldest daughter of the Duanmu family who had run away from home. The two of them worked together with Ding Feng and other partners to defeat the plots of He Tianrui, Tan Wenyao and other villains, gradually monopolizing the second-hand market, and entered the fields of second-hand cars and real estate. They also helped Mu Qiuyue regain the family rights and interests, and finally counterattacked in the second-hand market to build a business empire. The two finally got married.
