The Shattered Realm Pearl

Chen Xuan, erased from the records by his sworn brother and the person who shared his bed, is reborn in the body of Lin Yue, a sickly young man from the Lower Third Ward. When a bead grows hot, he can see how another person's "qi" flows. The price is temporary blindness and deafness, and having to spend a lifespan he barely has left. No qi in his own body? He can borrow the half-breath of qi you exhale and shift a spell just half an inch off course. But the qi in the spiritual dregs is so evenly distributed it might as well have been weighed. The ledger has a blank space for the prescription, the ward school's qi technique is missing a line, and someone tore out several pages of old records three years ago. The next day, he fell ill.

Above the Nine Pillars, someone has been going through the records all along.
