Ye Chen, a young man from Lingzhou, was originally a genius that the sect had high hopes for. However, on the eve of the establishment of the foundation, he was betrayed by his best friend. He was expelled from the sect and became an outcast who could be bullied by everyone. When he was about to die, he accidentally awakened the remnant soul of the ancient Taoist monk sleeping in his body. He changed his name to Xuan Chen and wandered around the world as a casual cultivator.
During the day, he is the low-key and tolerant Ye Chen, trading scraps in the market, surviving in the cracks of secret realms, relying on the Taoist inheritance to repair his spiritual roots, and practicing the "Nine Heavens Royal Taoist Secrets"; at night, he transforms into the mysterious Xuan Chen, killing enemies in the black market, deciphering ancient formations for top forces, and shocking everyone with his alchemy skills.
When the righteous encirclement and suppression of the Demon Cave is in a dead end, and when the thousand-year blood curse is about to devour the continent, the secrets of the two identities gradually overlap. Ye Chen breaks the formation with his sword, and Xuan Chen seals the demon with his palm seal. The abandoned son in the past will finally use his dual identity to crush Ling Xiao, uncover the shocking secret of the sect's betrayal and the dispute between Tao and demons, and become the real Taoist Master of Jiuxiao!
