Youth Lin Xiaoman accidentally crosses into the withered spring dead land, forced overnight to shoulder the legend of bone tempering. He embarks on a journey to find the truth behind the nine dragons' withered bones, fortuitously meeting the innocent little girl Baituan, while the friend-turned-enemy Tieya, the deep-scheming Jinse, and the fairy court princess Bailu successively enter the fray. Amidst the blood tax of Xucheng, the dragon vein withered bones, and the sound of horse hooves, various factions vie in secret and open struggle for the secret power controlling the world. Step by step, Lin Xiaoman is refined from an ignorant mortal into the fire-bearer, shaking the old order that subverts the fairy court amidst repeated life-and-death banquets and tragic choices. When the truth surfaces, in the season finale battle, he must make a fate-rewriting choice between power and morality.
