Hard Training? I’ll Just Go All In on Power-Ups!

[Advanced martial arts + feel-good power fantasy + ruthless protagonist + fast-paced + lighthearted + overwhelming victories]

He's in a world of advanced martial arts, but he can't cultivate any techniques. He has only six months to live, and even his girlfriend of two and a half years has run off into another man's arms.

At the brink of despair, Ning Fan awakens the Immunity System.

If the righteous path has no place for me, then I'll join the demonic path!

Demonic techniques come at a price? I'll make myself immune to every last one!

No matter what the demonic art is or what price it demands, I'll take them all!

While others pay with their lifespans or sacrifice their organs to use demonic arts, Ning Fan has already become immune to the cost and raised each technique to perfection.

“Ning Fan, do you know the price of cultivating this demonic art? It drains all the essence and blood from your body. You can't withstand it! ...Wait, how did you learn it?!”

“Sorry, Ning Fan, I'm actually a spy! ...What, you are too? How could someone as sinister as you be a spy?!”

“Ning Fan, demonic arts will never be respectable. The righteous path is the center of the world! ...What? You beat every new student on your own?!”

“Ning Fan, how dare you destroy the Church! I'll tear you limb from limb! ...Wait, you clearly practice demonic arts, so why aren't you under my control? No, how did I end up under your control?!”

“Don't be ridiculous, Ning Fan. Those are prodigies from an alien race. You can't possibly... What? You took care of all of them while you were at it?!”

The Evil God descends, turning the land into a slaughterhouse of flesh and blood.

Unfathomable beings invade from beyond the skies, while countless alien races set their sights on the human world. The world is plunged into its darkest hour.

Ning Fan bears the heavens alone, shrouded in overwhelming demonic energy, and suppresses all who stand in his way!
