Qin Mo originally came from a humble background and had a bad fate. In order to survive the family, he was forced to become the son-in-law of the wealthy Chu family, and suffered humiliation and exclusion. He tolerated it and pretended to be a pig to eat the tiger, and he worked step by step, relying on his past knowledge and hidden skills to establish his own power in the cracks. As the Chu family's civil strife intensifies, undercurrents of business and underworld forces surge. Qin Mo relies on his resourcefulness to gradually uncover a series of deep secrets such as his wife's life experience, and unites former allies and emerging forces to not only avenge the insults he suffered in the past, but also settle the family blood feud. When his personal destiny, emotional struggles, and the great changes of his family, country, and times intersect, Qin Mo finally seizes the power, completes his counterattack from son-in-law to a man of the hour, and also obtains self-salvation and emotional destiny. The whole book is multi-faceted, closely following the main theme, and realistic and rigorous.
