A Demonic Cultivator's Compassion: I'll Slaughter My Way Through the Apocalypse for Merit

[Zombies + Dual-World Apocalypse. Also known as: I'm a Dual-Cultivation Demon, Following the Yellow Emperor's Example to Ascend by Day]

Han Fei transmigrates to Jiuzhou, inherits the legacy of a Demon Lord, and is hunted by both righteous and demonic factions, with his life hanging by a thread.

Fortunately, he activates the Myriad Heavens Merit System. By spending merit, he can upgrade anything with a single click.

To help Han Fei grow stronger without distractions, the System specially opens a passage to the apocalypse.

Han Fei transmigrates to one post-apocalyptic world after another, racking up merit and maxing out every skill.

[Host has slain a zombie]

[Merit +1+1+1...]

He upgrades his alchemy with a few points, and the pills he casually makes earn the adoration of countless top experts.

He upgrades his artifact-refining with a few points, and the magical treasures he makes on a whim are the most precious treasures guarding other sects.

He upgrades his fireball spell with a few points, and every attack blankets the sky in endless karmic flames, annihilating all living beings.

He upgrades his ice spell with a few points, and with a single thought freezes the heavens and earth, the eternal river of time, and all of time itself...

Countless years later, Han Fei rules over the ages. Looking back, he says, “Sure, I refine corpses, raise ghosts, practice gu, abduct immortals, and have killed countless people, but I'm a compassionate demon cultivator, the kind who slaughters his way through the apocalypse and attains sainthood through merit!”
