Dragon' s Vow

The ancient Black Dragon King Kale was betrayed by his brother Draco, the White Dragon King. His body shattered and only his soul was reincarnated as an F-class little black dragon. He was contracted by the kind girl Celia, unlocked the devouring evolution system, and gradually regained his strength by absorbing monsters and elemental crystals. Kale crushed the aristocratic children who mocked Celia all the way, conquered the old members of the Black Dragon in various secret realms, collected nine dragon powers and ten blades, and met Elizabeth, who had an unsullied spirit body, and Alice, a descendant of the Dragon Clan. White Dragon King Della continues to send White Dragon Guards to chase and kill. The college antagonist Blake and the noble Tovad set up traps one after another to harm. Kyle collects Thousand Spirit Stones in the secret realm of the sky, learns the power of the Dragon Emperor, collects a complete sword formation with ten blades, and finally fights against Draco in the sky above the Supreme Academy, seals the enemy, and guards the peace between the human and dragon races with Celia and Elizabeth, taking charge of the territory of ten thousand dragons.
