You Were Told to Be a Demon-Suppressing Guard, and You Became a Living God of Slaughter?

In the Great Qin Dynasty, demons plunge the world into chaos, eldritch horrors run rampant, and ordinary lives are worth less than weeds!

Su Yu transmigrates into this world with a Slaughter System of his own!

[Ding! Mortal Realm demon slain. Gained 30 Slaughter Points!]
[Spent 100 Slaughter Points. Raging Gale Saber Technique → Ultimate Killing Move: Traceless Windfall]
[Ding! Thousand-Year Corpse King slain. Gained 10,000 Slaughter Points!]
[Spent 10,000 Slaughter Points. Mortal Flesh → Hell-Suppressing Divine Physique!]

As long as there are monsters to kill, there are no bottlenecks to his cultivation!

Gazing at a city teeming with demons, Su Yu breaks into a kindly smile!

A passerby says, "Has that Demon-Suppressing Guard gone mad? He charged into the Den of Ten Thousand Demons all by himself!"

Three days later.

Su Yu emerges drenched in blood, leaving mountains of corpses and seas of blood behind him as system notifications ring out incessantly.

[Slaughter Points +...]

Years later, heavenly demons from beyond the realm invade, and all races bow in submission. With only his saber in hand, Su Yu stands high above the heavens, looking down upon billions of demons.

Su Yu grins, baring his chillingly white teeth. "Today, not a single one of you is getting away."

The First Emperor says, "Su Yu, you are the greatest calamity in this world!"
