Lin Qingyuan, who once terrorized the underground world in the name of the God of War, was forced to retire due to a complicated injustice case. He married into a wealthy family incognito and became a "son-in-law." Facing the contempt, provocations and conspiracies from inside and outside the Yue family, he kept a low profile and worked step by step. He not only had to protect his lover Song Yao, resolve family disputes, but also had to deal with years of grudges and the sudden reunion of his former partners. Multiple story lines are intertwined and advanced: family intrigues, the resurgence of dark forces, the reunion of old loves and family ties, and dangers everywhere. In the continuous fighting and choices, Lin Qingyuan gradually shed the heavy shackles of the past, led the Song family to break through and rise, and also evoked the passionate tenderness and past glory in his heart. In the final chapter, he faced his former mortal enemy and fate, and once again emerged as a new generation of king and god of war.
