Shangguan Dao's trump card

Shangguan Daodao, who runs a wine business under an assumed name, is a descendant of a former master strategist in the business world. Years ago, Lao Gui framed his father, seizing an ocean liner and maliciously swindling its customers. His fellow disciple Zhou Ming was trapped and in debt, while his childhood sweetheart Lin Qingqian was held hostage. Shangguan Daodao disguised himself as a customer and boarded the ship, secretly gathering evidence with his excellent judgment. He repeatedly dealt with Manli, who was being coerced by Lao Gui. After realizing the evil deeds of Lao Gui, Manli chose to help him. Shangguan Daodao devised a plan to expose all the illegal activities, preserving complete evidence. With the cooperation of law enforcement, the criminal gang was brought to justice, the victims were rescued, and the perpetrators were punished according to law.
