The Hidden Supreme of the Sect

Kaelen Grove transmigrated into a xianxia world, gaining a system. He pretends to be an ordinary mortal, not cultivating, only doing chores. Everyone thinks he's a good-for-nothing. The Azure Sea Sect assigns him junior sister Liora Lu. Liora, a great power's reincarnation, hides her talent, pretending to be a good-for-nothing. Assigned to Evergreen Palace, she finds her senior brother also seems a good-for-nothing... or is he?
