In an age where everyone practices cultivation, I—thanks to a twisted system—am tasked with becoming a demon lord?

[Ding! Congratulations, Host, you’ve bound the Chaos-Bringing System. As long as you complete demon-lord-style missions, you can ascend as the Supreme Demon!]

“System, are you kidding? This is the civilized age of cultivation, and you want me to be a villain? Are you trying to get me killed?”

[Mission 1: As a true demon, killing and stealing treasures should be as natural as eating and drinking. Seize others’ fortunes and make them your own.]

“That’s illegal! Robbery means three to ten years in prison!”

[Mission 2: A demon lord should lead countless followers, each willingly offering tribute to aid your path. Recruit 1000 followers.]

“That's a cult! The last one got disbanded and sentenced!”

[Mission 3: You’re now qualified. Refine your first demonic artifact—the Banner of Ten Thousand Souls.]

“Trading souls is capital punishment! This system is out for my life!”

…

“What? Stealing someone’s food delivery is seizing fortune too?”

“What? Livestream selling counts as recruiting followers?”

“What? AI-generated digital life can be used in artifact refinement?”

“You’re not a system—you’re my dad!”

…

Years later, after completing mission after mission through food delivery jobs, streaming, and online trolling, Su Yuan becomes the fearsome Supreme Demon—yet the world bestows upon him an unexpected title:

The Working Immortal.
