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 looked at Blazren and shrugged.

"If you really believe there's someone behind Velvet Demon," he said, "then go find out who it is."

Zain raised an eyebrow. "Why not?"

Blazren leaned on the table beside him, eyes tired.

"Velvet Demon is already AA-Rank. Not just barely—she's solid."

Blazren's eyes narrowed. "If there's someone behind her, they're even more terrifying."

Blazren continued. "I'm just A-Rank."

"I don't have the power or the access to track someone like that."

Zain spoke again, casual. "Then why don't you ask an AA-Rank hero to help?"

Blazren let out a dry laugh. "That's the problem."

"They're too arrogant," he said. "Most of them act like they're above everyone."

Zain smirked a little. "And yet, you still need them."
