Coffin of the Heavens

After his clan is massacred, fifteen-year-old Lin Yuan is forced to open the ancient nine-layer evil-suppressing coffin passed down for millennia. Using his lifespan as fuel, emotions as sacrifice, and memories as payment, he embarks on a path of guarding the coffin with no return. The stronger he becomes, the faster he forgets; the deeper his cultivation, the colder his heart. From a restrained and affectionate youth, he gradually turns into a lonely coffin guardian with withered emotions and shattered memories. His hair turns white, his face ages prematurely—every gain in power is repayment for the heavy karma of a past life sacrificed to the heavens. This is not a power fantasy; it leaves its mark through pain and regret. Friendship burns out, family is buried, warmth is severed, humanity is stripped away. Above the true immortals, the eternal truth is unveiled—his lifelong revenge is actually a grand scheme to resurrect his past life. From the mortal realm to the myriad heavens, from body refinement to Dao Lord. Along the way, he loses, forgets, and laments. There is no happy ending, only the lingering aftertaste of fate. In the end, he transforms into the Dao, forever suppressing the darkness of the heavens. This life has no joy, no warmth, no return—only an ancient coffin accompanying him in eternal solitude.
