Su Qingyuan, a modern paleontologist, was accidentally involved in the turbulence of time and space while studying a suspected phoenix egg fossil. When he opened his eyes, he turned into a young phoenix that had just hatched from the nine heavens. Carrying the "fire of Nirvana" but not yet enlightened, he was picked up by the passing Cang Yuan and brought back to the abyss lair.
Cang Yuan is the oldest living creature in this "Xuanhuang Continent" and the supreme dragon clan. He has guarded the "Netherworld Abyss" where the ancient ferocious beasts have been sealed for thousands of years. He has a cold and aloof temperament and regards all things as dust. When he adopted the young phoenix, he originally wanted to refine the only true phoenix fire in the world into a "container" that could suppress the ferocious beasts. However, he did not expect that this small furry fireball would stir up huge waves in the frozen lake of his heart.
From the "incompatible relationship between fire and water" when the young Phoenix was young - she pecked his scales, and he froze her tail feathers; to the tit-for-tat confrontation as an adult - she drew a sword with him to protect the Phoenix clan's heritage, and he violated the laws of heaven to protect her; to the revelation of the blood feud between the two clans in the ancient war, they were repeatedly pulled on the edge of love and hate. When the seal of the Netherworld Abyss loosened, ferocious beasts broke out, and the Xuanhuang Continent faced the crisis of destruction, this pair of destined natural enemies and lovers finally understood: the so-called love and killing are just the bonds that have been written by fate - her red feathers can burn his mysterious scales, and his Abyssal Power can extinguish her fire, but only the bond deep in each other's souls cannot be burned or frozen.
