I'm Really Not the Demon King

Zheng Xian was reborn as a small Taoist disciple, but was sent to the Demon Sect as an undercover agent. As a Taoist disciple, I work undercover in the Demon Sect. Year after year, if you don't let me go back, I will become the Demon King! In order to survive in the cruel demon sect, Zheng Xian tried his best not to cause trouble, but he was always ashes when he made a move. He planned everything before he did anything, hugging his thighs, hiding his trump cards, and refining poison pills.

I am really not the Demon King, I am also a member of the Taoist sect...
