The Mad Undercover Demon King

Some mysterious big shot from the Nine Heavens Immortal Realm was unbearably bored and wanted to play spy games among the Three Realms.

And so, Cheng Ren became the unfortunate victim.

One moment, he was still “enjoying” the blessings of the 996 work schedule. The next, he woke up transformed into a black-eyed, nine-clawed golden roc!

The Seven-Star Grass of the Nine Heavens gave him an inexhaustible supply of powerful energy. After refining himself into a demon, he was sent to the mortal world as a spy on the orders of a great demon king.

His master said he had a real demonic streak, and that it would be a shame not to go to the Demon Realm and gather intelligence!

The great demon king said, “I've got a secret manual for demon cultivation. Go to the Demon Realm and keep a close eye on things for me!”

The big shot said, “The calamity of the Three Realms is upon us.” What was going on? Had someone picked up the wrong script?!
