Xuanhuan: The Ultimate Undercover Agent

He transmigrates to a fantasy world with a Villain System in his head!

He thought he could bully a few princes and swindle some lovely young immortals, but instead, he was unexpectedly sent to infiltrate the Demonic Sect.

Three years, then another three years, and Gao Yuan has become the sect master of the Demonic Sect.

When a spy from the righteous sects comes to make contact, Gao Yuan cuts him down without hesitation.

Then he declares righteously, "Our Demonic Sect is going to unite the world!"
