Part-time BOSS

The princess locked up in the evil dragon's house is just like the yacht raised by the rich. The second best thing is to use it or not. The key is that you can't live without it. It is best to have several bounty tasks attached. The higher the task level, the better. If there is a dragon slaying The mission would be even better, this is what we want.
If you didn't have a princess in your family who would curse you to hell every day, you would be embarrassed to say hello to other evil dragons.

Hahaha, I am a dignified level 80 Black Dragon Lord, a world-class BOSS, how can I take this group of adventurers seriously?
What! The adventurer has already reached the outside of the dungeon? They are all full-level players, and there are two heroes leading the team! The leader of the team is still a dragon-slaying swordsman! It's over, what should I do now...
Heroes and villains, black dragons and mortals, the powerful BOSS in the game and the little anchor in reality.
This is a story about the Black Dragon BOSS player.
