Kunlun, Ashes!

Born a slave on Kunlun's sacred peak, Bai Ze endured a life beneath the immortals—his bloodline stolen, his name erased, his very existence deemed worthless. Day after day, he crawled like dust under the heel of Bai Jinghong, the cold-eyed heir who saw him as nothing more than a resource to be exploited. When the young master rips out Bai Ze's 'waste bone' in pursuit of supreme cultivation and casts him into the spirit-severed Burial Immortal Cold Abyss, he thinks he's discarding trash. He doesn't know that bone held a secret—and that the abyss will forge what heaven tried to destroy.
