Three years after his marriage, Chen Mo lived like a transparent person in the Jiang family until he found a scrapped Nokia in the old mobile phone market, with a dragon pattern flashing through the cracks in the screen. That night, the black market bounty in the city went viral, and the missing old subordinates, information dealers disguised as scalpers, and even his contemptuous mother-in-law all began to circle around this mobile phone. Chen Mo just wanted to repair his mobile phone and earn some pocket money, but he found that with the touch of his fingertips, the black market trading system automatically popped up the 'Dragon Head Certification'. He was forced to get involved in the fight, and his wife Jiang Wanqing also discovered his secret-it turned out that the abandoned son-in-law she married was the king of the underground world who had been missing for three years. But if he wants to regain control of his old ministry, he must first pass through the resource blockade set up by his mother-in-law, and he must also be wary of Lao Zhou, who helps him investigate the case. He seems to have other agendas.
