In the mid-Ming Dynasty, the eunuchs took power and the court was cruel and unkind. Their minions, Jin Yiwei and Dongchang, fought constantly on the one hand and were brutal to the people on the other. The entire martial arts world was full of blood and two camps formed. One side is a knight-errant who acts righteously and is not afraid of power; the other side is a factory guard lackey who betrays the justice of martial arts. The 6-year-old protagonist Mo Yu survived after his family was wiped out. The heroine was introduced to the Duanchen Sect. After 12 years of training, Mo Yu stepped into this chaotic world. What awaits him is not only endless danger and calculation, but also his life-or-death love.
