Journey to the West: I, the Sweeping Star, Grow Stronger by Sweeping

Zhong Cheng was desperate. He had transmigrated. But of all the things he could have become, why did he have to transmigrate into the universally despised Jinx? And it wasn't even quite like the myths: he really had become a Star Sweeper, in charge of sanitation in the Heavenly Court?! Fortunately, he was bound to a System that made him stronger by sweeping. Sweeping the Divine Powers Hall earned him the Nine Revolutions Origin Art. Sweeping the True Lord's Shrine earned him ancient double pupils... From then on, immortal life was just this boring: he swept floors and became invincible!
