How Did I Become the Big Villain?

[Sign-in story, invincible power fantasy]

If immortality is out of reach, become a demon!

After transmigrating to an immortal cultivation world, Zhang Ze discovers he has a body cursed by the heavens, leaving him with no chance of becoming an immortal. With no other choice, he devotes himself to demonic cultivation in search of eternal life.

The righteous factions hunt him down, and the immortal sects soon move to surround him. Fortunately, he awakens a sign-in System:

“Ding! Sign in before the Heavenly Demon Stele and receive: The Demonic Path Heavenly Tome!”

“Ding! Sign in at the Fallen Immortal Abyss and receive: The Immortal-Demon Halberd!”

Thus begins Zhang Ze's path as a villain!

In the peaceful mortal realm, he tramples the immortal sects and sweeps across the Nine Provinces. In the ancient primordial wilderness, he wages bloody battles, his demonic aura soaring to the heavens. In the Eight Wastelands Immortal Domain, he stands alone against the Immortal Emperor and claims supremacy with a single hand.

“I am the Demon Emperor. I shall wield the divine halberd and slay every enemy beneath the heavens!”
