On the night when the broken sword was reforged, Li Zhishuang cut out his heart and took blood to sacrifice the blade. He broke through the sky with one sword and made the world crazy. Xie Jinhou, who once broke his sword for her and went into seclusion, pulled out the sword stained with her tears and bones in the rain of blood, and asked with a smile: "You are crazy, I will accompany you to kill the so-called righteous way." She is not a demon, but a sword soul who was forced to become a demon by the world; he is not a knight, but a madman who is willing to fall into hell to burn out the rest of his life for her. There are rumors in the world that Li Zheshuang's sword will be stained with blood, and Xie Jinhou's smile will break his soul - but no one knows that every inch of the sword in his hand is rusted for her, and he lives for her.
