On a snowy night in the far north, the nine-headed demon god Xiang Liu picked up a cursed little fox demon, named him Ji Xiaoyao, and took him as his only apprentice.
The years in the Valley of Ten Thousand Demons were gentle and affectionate. He taught her how to practice and protected her, but little did he know that this clingy disciple was actually the emperor of the Fox Clan who was responsible for the Heaven-Mending Bone, and she was the key to maintaining the boundaries of the Three Realms.
When the demon clan broke the seal, the seven sects rebelled, and ancient secrets were revealed layer by layer, he was willing to sacrifice eight heads in exchange for her safety, and she was willing to offer him three lives in exchange for the Sky-Mending Bone.
The bond that spans thousands of years is master and disciple, confidant, and each other's only salvation.
