Xiao Tiance, the God of War, guarded the country for five years and guarded the reunion of thousands of families in bloody battles. When he returned, he found that his biological daughter Xiao Nianjun had been abandoned in a doghouse by his sister-in-law Zhao Yufeng, and was left to eat scraps and suffered all kinds of abuse. The former iron-blooded god of war was furious, and the mark of the god of war, which had been dormant for five years, suddenly awakened. Hundreds of thousands of his old troops moved upon hearing the order, and flattened the city just to protect his daughter Zhou. From cleaning up the family property, liquidating the villains, to overturning the black network of power and money behind his back, Xiao Tiance used thunderous means to repay the blood debt, and used iron and blood to hold up a clear sky for his daughter. The secrets behind his daughter's life experience, the truth behind his wife's disappearance, and the old enemies and forces lurking in the dark were also revealed layer by layer with his return, and a storm sweeping the city and even the wider world began.
