Five years ago, Xiao Yi married into the Su family to repay his kindness. He suffered humiliation and was treated as a waste. However, his true identity is the god of war who frightens his enemies on the battlefield. Five years later, the border war subsided and Xiao Yi was ordered to return to the city. In order to protect his family, he had to gradually show his strength. In the mall, he strategized and worked step by step to help the Su family get out of trouble and achieve business dominance. In secret, he kills demons, punishes rape and evil, and protects the peace of the city. As Xiao Yi's strength continues to show, more and more conspiracies surface. It turns out that it was not an accident that Xiao Yi was forced to remain anonymous, but someone was behind it. In order to expose the truth and clear his name, Xiao Yi launched a fierce struggle with various forces, and finally shattered the enemy's conspiracy and became the patron saint of the city.
