Lin Chengyuan, an iron-blooded soldier who had made great achievements in the army, became the Yan family's son-in-law incognito because his family was persecuted and fell apart. The Yan family is extremely powerful, and they both use and despise Lin Chengyuan. He is deeply involved in family disputes, status exclusion, and plots by foreign enemies. Faced with the complex and ever-changing family structure and threats from external forces, Lin Chengyuan relied on his military qualities and extraordinary courage to break through the situation step by step; he also gradually grew up in the fetters of his wife Yan Rujiao, his sister Lin Yuxin, and his brother Gao Zhongan. As the underlying conspiracy and truth gradually surfaced, Lin Chengyuan not only avenged the murder, but also tried to protect family and love and achieve self-salvation. The story progresses on multiple lines, including family grievances, political and business competition, personal growth and emotional evolution, and unfolds layer by layer.
