Azure Bone

In the vast wilderness world, where immortal sects stand like forests and mortals are as insignificant as ants, young Chen Yuan is born into a family of border mine slaves. With his father dead and his mother ill, he descends into the mines at twelve to dig spirit stones in exchange for herbs. During a mining accident, he unexpectedly obtains a section of azure spine from an unknown era. After it fuses into his body, he can devour the essence blood of demon beasts to nourish himself, but it also continuously erodes his sanity. To survive and uncover the truth behind his father's death, Chen Yuan enters the Xuantian Sect as a handyman, starting from the lowest sweeper boy in the outer sect. Amidst sect infighting, aristocratic oppression, and beast tides, he uses the bone as a blade and his life as a stake, step by step ascending to the azure firmament.
