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 and Stoneclaw walked through the main gates of the Hero Association.

Several heroes turned. Conversations dropped.

But everyone looked when they saw the two corpses being dragged behind them.

Blood-stained. Burned. Clearly executed.

One of the guards blinked in surprise.

"Those are—wait… are those Blast and Blunt?"

Zain tossed down a blood-crusted ID card.

The guard looked at the bodies again, then waved over staff.

Two white-coated workers rushed over with containment gear.

Zain stepped back, letting them haul the bodies away.

Once the IDs were confirmed, the clerk gave a quick nod.

"Confirmed… both B-Rank fugitives. You're cleared."

Zain turned without a word. Stoneclaw followed.

They made their way straight to Savra's office.

A-Rank or Bust!
