Jiang Ci, the empress of Beijing's elite circles, is pressured by her family into marriage, and a contract is thrust before Sun Jin, the "golden matchmaker for whirlwind weddings." Everyone in the city knows Sun Jin as a live-in son-in-law who lives off his wife. No one knows that he's also Zhulong, the number-one name on the darknet's bounty list. After the wedding, Sun Jin has his hands full. By day, he's his CEO wife's personal assistant, pouring tea and water, taking scoldings, and diligently keeping up his useless son-in-law act. By night, he's Zhulong, the king of the underworld, able to turn the world upside down. He even has to find time to trade secret identities with his wife's secret admirer, Lu Tianhao, the bully of the Black Gold Empire.
Lu Tianhao thinks Sun Jin is just a useless freeloader living off his wife's inheritance. He laughs and boasts that he'll kick Sun Jin out in three days. Sun Jin laughs too. "Sorry, the woman you want is my wife. I'm the boss of the underground world you run in. And the weapons you're hoping to buy... they're on my inventory list." As secret identity after secret identity is exposed, the capital is shaken. Jiang Ci looks at the unfamiliar man before her and slowly raises the divorce papers. "How much are you still hiding from me?" Sun Jin sighs. "Honey, first tell me: why are you one of the Three Judges of the Yama Hall?"
