Protecting the country, Grand General He Lin guarded the borders for ten years. Returning victorious, he discovered his biological daughter was replaced by an impostor and thrown into a brothel with her tendons cut by the four unfilial sons he had adopted, lingering on the edge of death. The iron-blooded general launched a thunderous revenge, tearing apart layers of conspiracies with his military power and murderous aura, forcing the palace to depose the crown prince, and settling scores with all enemies one by one. He used ten years of military achievements in exchange for justice for his daughter, and the rest of his life to protect her safety. In the end, father and daughter stood side by side to guard their home and country.
