Ye Xian transmigrated to a fantasy world and became a low-ranking disciple of the Qingyun Sect, with terrible aptitude and everyone picking on him. He also got an unreliable [Slacker's Anti-Grind System]: the lazier he is, the more he grumbles, and the less he plays by the rules, the more absurd the rewards he gets!
