Lin An, a menial disciple with a useless spiritual root, was a discarded child of the immortal path, doomed to remain stuck in the servants' quarters with no hope of ever rising.
By chance, he obtains an ancient, incomplete Heaven-Mending Mirror. He accumulates Heaven-Mending power by repairing magical artifacts, gradually restoring his shattered spiritual root and overturning his fate as a born failure.
Oppression from those at the bottom, provocations from the strong, and harassment from the stewards: danger lurks at every turn.
One hammer repairs broken artifacts; one mirror rewrites fate.
He rises from the mire and strides against the tide onto the immortal path.
