The Sect of the Lost Heir.

In a forgotten lower world, Lin Yuan grew up as an orphan, convinced he had been abandoned at birth. His only clue to his origin is a dull gray medallion that seems completely worthless, a strange object no one in his remote region can recognize. When he tries to enter the Grey Cloud Sect to change his fate, he discovers that his spiritual meridians are severely damaged and is publicly humiliated as trash incapable of cultivation. But just when his life seems to have reached its end, a dimensional rift drags him into an impossible inheritance: the Supreme Sect Foundation System. Instead of turning him into a lone warrior, the system gives him a far greater mission—to found a sect, raise monstrous disciples, and lead it to a height that can challenge the heavens. With his meridians only partially repaired, a sealed legacy hidden within the Firmament-Sealed Medallion, and a ruined mountain as his only starting point, Lin Yuan must build the Primordial Firmament Sect from nothing. As he gathers the world's discarded talents and faces clans, sects, and hidden enemies, the mystery of his past begins to awaken. The medallion that protected him when he was a baby does not belong to that world, and all signs point to the truth that Lin Yuan is no ordinary orphan, but the lost heir of the mighty Lin Family of the Celestial Firmament, one of the great bloodlines of the higher worlds. From humiliation to ascension, Lin Yuan will walk a path of blood, glory, loss, and conquest to discover who cast him into the abyss... and why the heavens are not done with him yet.
