Villain System: You Were Told to Go Undercover, Not Seduce Your Master!

In his previous life, Lu Yuan devoted himself heart and soul to the righteous path, only to have his hypocritical master drain his marrow and bones before he died beneath her sword.

Reborn, he returned to the day he was sent undercover to the Demon Sect.

The head of the righteous sect made lofty promises: “My disciple, spend ten years infiltrating the Demon Sect. The future of the righteous path rests on you!”

Lu Yuan sneered inwardly, then turned around and joined the Demon Sect, awakening the [Supreme Villain System]! Villains get rewards, so whoever wants to be a spy can do it themselves!

Who knew that as soon as he entered the Demon Sect, its icy, peerlessly beautiful mistress would set her sights on him, intending to use him as a cultivation furnace and drain him of all his power!

“Ding! Villain choice triggered!”

“Option One: Hold fast to the righteous path. Reward: Your soul will be scattered!”

“Option Two: Turn the tables and win over your master! Reward: Heaven-Devouring Demonic Physique, a massive boost in cultivation!”

Lu Yuan promptly chose the second option, pinning his aloof master against the wall. “Forgive me, Master!”

…

Several years later, the alliance of righteous sects was surrounded on all sides by the demonic army.

The head of the righteous sect frantically squeezed his voice transmission talisman. “My good disciple, where’s the intelligence? Hurry up and close the net! The righteous path is about to be wiped out!”

On the throne of the Demon Realm, Lu Yuan held the Demon Sect’s female emperor in his arms and crushed the jade talisman with a sneer. “Close the net? You old geezer, I’ve been the Demon Lord for ages. Prepare to die!”
