The story takes place in the fictional Jiangnan city in modern times. Due to a special secret, Xu Mohan became anonymous and married into the Xu family. His apparent status is humble, but he conceals his power, ingenuity and bloodiness as the God of War. He not only has to deal with the overt and covert struggles within the family (for power, family ties, marriage) and the coveting of external interest groups, but he also has to resolve threats and old enemies from the past. As the situation in the family, city and country becomes increasingly tense, Xu Mohan gradually breaks through the shackles and takes on the important task of saving his family and his loved ones in the storm. In the multi-faceted intertwining of court power, black and white fights, emotional entanglements and self-salvation, he eventually became everyone's reliance and spiritual guardian. The novel progresses on many fronts: the protagonist's self-growth; the Xu family's split and reorganization; emotional triangles and ethical choices; national turmoil and social security, all of which converge at the climax.
