In his previous life, Wang Dazhu wasted his life on drinking and gambling, eventually falling into poverty and freezing to death on the streets. Reborn on the day his father died and the family divided their inheritance, he unexpectedly discovers that he can understand his loyal dog Dahuang, who can spot treasures hidden among discarded junk that ordinary people would never notice. Determined to make up for his past regrets, Dazhu abandons his bad habits and starts over with a battered three-wheeled cart. With Dahuang and his mentor, Uncle Li, helping him learn scrap sorting, metal refining, and antique appraisal, he discovers silver ingots, valuable stamps, and rare metals among seemingly worthless scrap. Through hard work and honesty, he gradually establishes a construction cleanup crew and creates job opportunities for the villagers.
