In the beast world of Canglan, the tide of beasts is raging, and the five ancient beast tribes are looking for holy objects to quell the disaster.
Feng Qi of the Fire Phoenix Tribe is the jewel in the palm of their hands. She has a beautiful appearance and a healing aura, but she only remembers the little black snake she saved in her childhood. Ao Jin from the Black Dragon Clan is a rare and proud son of heaven. He is cold, arrogant, taciturn, and extremely possessive. His only obsession is to find the little ball of fire that warmed him back then.
In the Council of Five Tribes, the two were forced to team up to investigate the beast tide. When they first met, they were tit for tat, but as they experienced life and death together, they were attracted by the familiar aura of each other. Fragments of childhood appear in the fantasy world, the dragon scale jade pendant and the token of the newborn phoenix feather are recognized, and the dust-laden memories are finally awakened - it turns out that the people who have been looking for each other for half their lives have already formed an indissoluble bond when they were young.
After acknowledging each other, the sweetness is overwhelming. The cold black dragon transforms into a maniac who dotes on his wife, but is also plunged into a life-and-death crisis due to the conspiracy of the evil beast: Feng Qi destroyed the beast core to save Ao Jin's mother, and Ao Jin burned the dragon core to protect his lover. From one-way protection to fighting side by side, when the fire of nirvana met the black dragon flame, the two activated the ancient inheritance with their heart and soul, and finally became the dragon and phoenix gods of the Canglan beast world, working together to protect all things, and turning their millennium obsession into an eternal legend that will last a lifetime.
