Dragon originated from the famous Hong Kong cartoonist Ma Rongcheng's famous work Fengyun. Long Yuan is the true element of the dragon, which is condensed by the whole body essence of the dragon. It is something that has just arrived at the sun. Eat Long Yuan and you will live forever. Dragon-an island hidden in the lake of fire, somewhere in the sea in the middle of the lake, the residents of the island have guarded the "aquarium" for generations. More than 100 years ago, the ancestors of the water god of the Shui nationality entered the lake of fire to explore, and their hands were accidentally stained with dragon blood. Later, his skill was greatly improved, and his hands were invulnerable (similar to Kirin's arm). After his death, his body did not rot, and he was awakened and resurrected by the power of the fire unicorn, which is also the power of the beast in the fire sword. The aquarium regards the dragon as the patron saint of the aquarium, but the dragon is a ferocious beast without humanity, and it is the strongest and fiercest of the four auspicious beasts.
