The Dragon Lord and the Scourge Maid Group

As the new lord of Sharp Ridge, Blue Dragon always feels powerless. The elves in the forest are always harassing you, the orcs in the territory frequently rebel, and the treasures in the lair are often stolen by adventurers! His subordinates are all jackals, kobolds and the like, and he has to deal with them personally every time. Alas, there are warriors guarding the four sides~ The blue dragon sighed, is this the sorrow of a young dragon? Until one day, a fallen legendary paladin came to seek refuge, and the blue dragon suddenly understood the art of trading (deception). From then on, a simple and upright (questionable) blue dragon died, and a mature and cunning evil dragon lord was reborn! And under his throne, those fallen people who signed contracts were eventually cultivated into a natural disaster-level... Maid group?
