Description：Su Yishui (played by Deng Wei), a genius in immortal cultivation, had his destiny changed by his master Mu Qingge (played by Xiang Hanzhi) 18 years ago. The rebellious "female devil" Mu Qingge also died with a stigma for this. 18 years later, Mu Qingge became Xue Ranran, and Su Yishui, who had succeeded as the head of the Xishan School, took the weak and dying Ranran into his school, vowing to protect her for the rest of her life. Since then, the identities of master and apprentice have been swapped. What hilarious stories will happen between the two?
