The Black Dragon's Leisurely Life

He, a legendary being, he, invincible in all things.

His name is... the World-Ending Black Dragon, Nidhogg!

Some black dragon: Destroy what? I’m a peaceful herbivore, for crying out loud.

This is a story about a protagonist taking it easy while grinding powerful foes like they’re no more than cannon fodder.

The main world is original. The protagonist treats transmigrating as a long-distance journey, so it probably makes up only a little more than half the story.
