Legend has it that in the prehistoric world, the war between humans and demons has subsided. The remnants of the dragon clan who have contributed to killing the demon god and quelling the war are allowed to go to Jiutian Yaochi to purify the demonic energy and practice to ascend to heaven. In order to prevent the demons from absorbing the remaining essence, blood and resentment from the demon's tribulation, the gods retrieved the demon's weapons and recast the demon. Mingba led the dragon-guarding horses to guard the waters of Longtan. Every ninety-nine years, he turned the wheel of reincarnation and opened the Yaochi to the waters of Longtan. A divine dragon appeared in the world to guard the mortal world.
The demons secretly practiced to recast the demon god, and even planned to kill the dragon that came into the world this time to prevent it from preventing the demon god from reincarnating.
The demons invaded the waters of Longtan with a large number of troops, and the dragon-guarding horses retreated steadily. The injured Baxia turned the world of reincarnation in advance and fought to the death with the demons. Little did they know that a small white dragon appeared in the waters of Longtan. After stepping through the water, it transformed into a little girl wearing white clothes and golden skirts. She said her name was: Pang Tiantian. .
