I, the Living King Yama of the Demon-Suppression Bureau! Slay to Grow Stronger

[Decisive and ruthless] + [Rapid leveling and stat allocation] + [Invincible, with no needless suffering] [Multiple female leads; if that's not your thing, stay away]

Su Tianyi transmigrates as the lowest-ranking “dog” in the Demon Suppression Bureau, a nobody whose life hangs by a thread.

At the moment of crisis, the Slaughter and Stat Allocation System awakens! With swordsmanship perfected from the start, one slash blasts through a monster's skull, sending blood raining from the sky!

From then on, the Great Xia Dynasty has a living King of Hell.

A drought ghoul lays waste to hundreds of miles of Qingzhou. He splits the earth open three hundred zhang with his bare hands and burns away the corpse miasma. A flood dragon stirs up trouble in the Eastern Sea. He rips open its belly, digs out its core, and chews it up, as demon blood stains the heavens!

A Buddhist master condemns him for his overwhelming bloodlust. The next day, an arhat's golden body shatters, and the temple's chanting turns to screams!

When everyone tries to take on this King of Hell, they discover it's already too late.
