What if you could hack the strongest heroes and turn them into your devoted companions?

Once feared as the Heavenly Demon, Zain stood above all—unstoppable, unrivaled, unchallenged. 

But his reign came to an end when so-called righteous cultivators banded together to eliminate him, believing they had purged the world of its greatest evil.

Yet death was not the end.

Reborn in a world dominated by heroes and champions of justice, Zain awakens a mysterious Hero Hack System—a power that doesn’t just defeat heroes but rewrites them. 

With a single command, he can shatter their convictions, twist their destinies, and rebuild them into something new.

A ruthless warrior queen? Now a loyal blade at his side.
An untouchable holy maiden? Now eager to obey.
The strongest hero who once stood against him? Now kneeling before him, waiting for his command.

With every hero he hacks, his harem of once-unshakable warriors grows. But as he reshapes this world to his will, one question remains—who gave him this system, and what price will he have to pay?

They ended his reign once. This time, he’ll reign over them all.

The Broodlings and Sporeguards rushed at Zain, their claws out and eyes glowing.

They leaped at him, but their claws scratched only his skin.

Zain stood still, his arms crossed.

"You're not even worth dodging," he said.

The Sporelord's eye glowed, bile dripping from its mouth.

It activated [Brood Spawning], and the sacs on its back burst open.

Dozens of new Broodlings and Sporeguards poured out, eyes red and claws sharp.

"You think more of you will help?"

He grabbed a wooden stick from the ground.

His [Heavenly Demon Ether] glowed around it.

He swung it like a sword, using [Demon Slash].

A black wave shot out, cutting through the new monsters.

They fell to the ground in pieces, dissolving in green slime.

He turned to the Sporelord and swung again.

Because Slime is Money
