The immortal cultivator Su Yishui (played by Deng Wei) was changed in destiny by his master Mu Qingge (played by Xiang Hanzhi) eighteen years ago. Mu Qingge, a female devil who has always been rebellious, also died of stigma.Eighteen years later, Mu Qingge transformed into Xue Ranran, and Su Yishui, who had succeeded as the head of the Xishan Sect, took the frail and dying Ran Ran into his sect, vowing to protect her for the rest of her life. From then on, the identities of master and apprentice were swapped.What ridiculous stories will happen during this period?

Twenty years ago, Mu Qingge, the head of the Xishan Sect, offered a golden elixir to seal the spiritual spring on his disciple Su Yishui in order to protect the common people and prevent the monster spiritual spring from causing harm to the world.Mu Qingge's move was mistaken by the world for being a demon, and he was jointly killed by the four major Xuanmen.Disciple Su Yishui learned the truth before Mu Qingge's death, went through all kinds of dangers to find the reincarnation tree, and gave half a golden elixir to help Mu Qingge be reborn.Twenty years later, Mu Qingge was reincarnated as Xue Ranran. Su Yishui took the frail and dying Xue Ranran under his tutelage, vowing to protect her throughout her life.Now that the seal of Lingquan has been loosened again, Demon Cultivator Duntian wants to use Lingquan to recreate the devil, with the intention of harming living beings.Su Yishui kept Mu Qingge's instructions in mind and sealed the spiritual spring back to the netherworld at the cost of his own life.Su Yishui was framed by Duntian while sealing the spiritual spring and lost his memory.But even though she lost her memory, Su Yishui still fell in love with Xue Ranran again. Su Yishui and Xue Ranran joined hands and went through many hardships, and finally broke through Duntian's conspiracy, protected the people, and restored peace to the world.
