Five years ago, Gu Nanzheng was an invincible war god on the border battlefield. He was seriously injured during a mission. In order to avoid being pursued by his enemies and certain forces, he became anonymous and married into the Su family. In the Su family, he suffered cold looks and ridicule, and was regarded as an incompetent waste. His wife Su Wanqing is full of misunderstandings about him, and his father-in-law Su Guotao makes things difficult for him in every possible way. However, Gu Nanzheng always endured it silently and secretly protected his family. As the Su family faces crisis and former enemies appear, Gu Nanzheng is forced to gradually show his strength. While he was solving the Su family's dilemma, he was also investigating the truth of the incident that year. In the process, Su Wanqing gradually discovered Gu Nanzheng's true value, and their relationship heated up. In the end, Gu Nanzheng returned to the battlefield, exposed Li Hao's conspiracy, avenged his comrades, proved his worth, and won the respect of everyone. He defended national security with iron-blooded means and protected his family with sincere feelings.
