In ancient times, in order to break through to the highest realm, the Cangxuan dragon killed both good and evil thoughts, but it caused a catastrophe of three hundred years of cause and effect. Young Su Chen carries a mysterious jade pendant and awakens the dragon bloodline. In the process of practicing the "Nine Transformations of Cangxuan", he gradually reveals the truth about himself as a "container of good thoughts". When the seal of Beihai is broken and the ancient bronze palace appears, he must make a choice between strength and Taoist heart - to become the new Cang Xuan, or to break the cycle of reincarnation and redefine the laws of heaven and earth?
