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 sat on his couch again, legs kicked up.

His eyes were focused straight ahead, but his mind was racing.

Now that the system's updated…

It should know more about [Classes], right?

He raised a hand, flicked through his system menu, and grinned.

"Give me the full description of Skybrand's class."

"Her class is [Skybrand Duelist], isn't it?"

The system responded with a soft hum.

Then, text began to appear before his eyes.

[Class: Skybrand Duelist]

[Active Abilities:]

[Skybrand Shift: Grow wings and fly fast. Every move launches you. Every attack sends out air blasts. You stay in the air, hit hard, and stay hard to catch.]

So That’s What a Class Looks Like…
