He was bullied and was kicked out of the house when he was rescued by Chushuang, the first disciple of Nandou Tianyi. In the process of getting along, he fell in love with Chushuang. In order to be worthy of Chushuang, he improved his martial arts and stood out among the younger generations of the Mu family, but was feared by the direct descendants and framed. When Mu Fengduo's life was hanging by a thread, he was rescued by Queen Ai, who cursed the Mu family to "die in three generations", and was involved in the fight between Queen Ai and Mu Yunqi, the head of the Mu family. In order to wipe out the entire Mu family, Queen Ai released the Lord of the Dark Realm, and the world was in chaos.
