I thought it was just a game.
A disgusting NTR martial world I never should have touched.

Until I was betrayed by the one person I trusted most.

And then I woke up inside it.

Pang Yujin has been reborn into a corrupted martial world—
a realm twisted by betrayal, power, and filth.

Stranded on an uninhabited island, with nothing but modern knowledge and a broken body,
he realizes something simple:

this world cannot be fixed with fists or philosophy.

Only firepower can clean what is rotten.

From crude experiments to forbidden weapons,
from survival to revolution,
he begins forging a new path in the martial world—one built on gunpowder and wrath.

When he finally reenters civilization,
he joins Princess Hyejin’s army against pirates…
but the battlefield he returns to is far darker than expected.

conspiracies, betrayal, and rot hidden beneath martial honor begin to surface.

And this time, he has no intention of forgiving anyone.

Because in this world—

justice is not inherited. It is enforced.
