I Worked Hard for a Hundred Days as a Spy in the Demon Sect, Then Married the Female Emperor

"Jiang Xuan, you are the hope of the righteous path. We sent you undercover in the Demon Sect this time to win the trust of that female demon. Once you rise to a high position in the sect, we can coordinate from within and without and wipe it out!"

"That's right, Jiang Xuan. The great task of sweeping away the Demon Sect rests on your shoulders. Don't let the righteous path down!"

"We'll be waiting for good news from you in a hundred days!"

Jiang Xuan transmigrated to a world of immortal cultivation, becoming an undercover agent planted in the Demon Sect by the righteous path. He was even taken on as a disciple by the notorious female demon of the cultivation world!

Jiang Xuan was panic-stricken!

Ding! Congratulations, you have activated the God-Tier Undercover System. Undercover countdown: one hundred days. Good luck!

On the first day undercover, you receive: mastery of the Sword Dao!

On the second day undercover, you receive: a Twelfth-Grade Heavenly Demon Golden Lotus!

A hundred days later, the righteous sects surrounded and attacked the Demon Sect.

On that day, Jiang Xuan held the female emperor's hand.

"The righteous path? Do we even know each other?"

"Anyone who dares to offend my Demon Sect will be hunted down, no matter how far away!"
