Lin Yuan, who used to be an orphan from a martial arts family, has now become an insignificant son-in-law of the Su family. The outside world only sees him as humble and possessing nothing, but in his heart he is burning with hatred of family, country and pride of blood. In order to seek revenge, he hid his edge and worked step by step in family struggles and power turmoil. As the Su family is in crisis and enemy forces approach, he gradually demonstrates the power of the God of War, meets like-minded knights, joins forces to defend against powerful enemies, and regains the family's glory step by step. In the fog and darkness, parting and sacrifice, Lin Yuan completed his self-salvation, redefined the meaning of family, family, and love, and finally became a god of war. The book is spread out through multiple story lines, covering family fights, rivers and lakes friendships, business wars, foreign invasions, grievances and hatreds, etc. It has both cruel reality tests and tenderness to watch, with both depth and tension.
