Sign-In: I Raised Humanity for Three Years and Became the Demon King

In this divine world of swords and magic, Antuen is merely a mixed-blood demon.

Fortunately, his noble bloodline earns him a job at a ranch where humans are raised.

He thinks he's landed an easy job, but it turns out to be a massive trap left behind by the previous ranch owner.

If he fails to complete his tasks, the Demon King will have him executed.

Luckily, at the crucial moment, he awakens the Infinite Sign-In System. As long as he signs in every day, he can receive incredible rewards.

Everyone thinks he's just a ranch owner who raises human livestock.

But the army of ten thousand under his command storms cities and seizes territory, undefeated wherever it goes.

When the Demon King tries to seize his human army, he discovers...

That the little demon from three years ago has become a Demon King just like him!
