On the surface, Wugang City is a first-tier city where finance and shipping coexist. In fact, due to a "Qinglan Fault Incident" that was buried twenty years ago, an underground order where the powerful, capital, and old forces are entangled has formed. The protagonist Lu Chenzhou was once an ace agent of the secret operations team. After a mission failed, he took the blame and retired. After coming down from the mountain, he entered the Shen family as a "son-in-law" and secretly investigated the relationship between the truth of the accident and the annihilation of his master. The Shen family is in an awkward position among the local wealthy families in Wugang. Although the heroine Shen Qingzhi is very capable, she is suppressed by the family and the business world. Marriage is just a stop-gap measure for her to ward off the knife. As Lu Chenzhou took action step by step, the man-made "information gap" in the upper echelons of Wugang was torn open, leading to a dark network spanning chaebols, security groups and overseas forces.
