The little Taoist nun goes down the mountain to level up and fight monsters. She is supported by the Taoist genius male head of a southern family whose parents have made a marriage contract, and she is also pursued by the loyal dog male second, the future heir of a northern metaphysics family. The heroine is a weirdo when next to the hero, and she always wants to "kiss, hug, and lift him up." Seeing the man turn into a vicious-tongued girl in seconds, she said with a cold face that she cultivated the ruthless way. The male protagonist is affectionate and gentle and responds to the female protagonist's requests. The second male lead is domineering and arrogant and puts a family token of love on the female lead when they meet. The three people have been entangled since ancient times, and they are reunited in this life because they share the law of heaven.
