Thousands of years ago, Mu'er was an arrogant demon king. She led the demon tribe to expand its territory, and never thought of being destroyed by her opponents.
Fortunately, she didn't die and came back to life in the body of a cat;
Unfortunately, she forgot the fact that she was the Demon King, and lived a happy life of acting coquettishly and being cute, content to be just a rice bug.
Bai Shu has an enviable talent and an unparalleled family background. He has had high hopes since his birth. If nothing unexpected happens, he will become the strongest among the new generation of monster hunters.
But he didn't take the ordinary path. He betrayed his family for a monster and became an anomaly among monster hunters.
Unexpectedly, Mu'er, who was just waiting for death, met the down-and-out demon hunter Bai Shu. The two were destined to be enemies. They bound the contract by mistake, and Bai Shu became Mu'er's master.
In the process of protecting Bai Shu, Mu Er went from being afraid of Bai Shu to becoming deeply in love with her. She thought Bai Shu was the same to her, but she didn't expect that after Bai Shu became a demon hunter again, she would be the first demon he wanted to get rid of.
Bai Shu seemed to have everything, but he was just a perfect tool cultivated by his family. He rebelled and ran away from home, but he didn't expect to meet the kitten demon Mu'er. The kitten demon was weak in magic but very courageous. He couldn't drive him away no matter how he stayed by his side. Bai Shu disliked Mu'er from the beginning to treating him like a treasure, but he didn't expect that one day, he would personally crush his treasure.
