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.

Hero Hack: Reversing Heroes and Raising Harem

Zain walked through the hall, making his way to the receptionist.

A tall humanoid robot assistant turned toward him.

Zain smirked and set the cloth-wrapped sack down in front of the bot.

"I'm here to finish my hunting mission."

"A-Rank advancement trial. Name's Heavenly Demon."

The robot's optics scanned the sack briefly before turning back to him.

"Target: Karven. A-Rank rogue villain."

"Identity confirmed. Status: deceased."

"A-Rank qualification trial success."

"Please proceed to the advancement verification room. That way."

It raised a hand, pointing to a corridor to the left.

Zain nodded, lips curling into a grin.

He adjusted the strap over his shoulder.

He then walked down the hall, opening the door.
