Chen Mo, the legitimate son of the Chen family in Yunzhou, was originally a genius with extraordinary talent in alchemy. However, he lost his alchemy veins due to an explosion of an alchemy furnace ten years ago and became an abandoned son of the family. When his fiancée Chen Xueyao broke off their engagement in public, his father Chen Zhenyue stuffed a blood-stained half of the broken Nine Heavens Cauldron into his mouth in order to protect family secrets.

The two worked together to explore the Chiyang Sect and the Alchemy King Valley, and faced off against Chu Lingxiao, the young master of the Blood Soul Sect at the Nine Continent Alchemy Conference. However, they uncovered a bigger mystery - the one who massacred the Chen family back then was actually a disciple of the Demon Lord killed by Su Yan himself in his previous life!
