The Villain in Quick Time Is Just His Right Arm and Right Arm

Lu Yu was inexplicably born between heaven and earth. At first, she just sucked in human emotions as food. She doesn't know where she comes from or where she's going. Even though she feeds on emotions and desires, she doesn't understand anything. She lived in this ignorance for thousands of years, and then one day, she began to be curious about everything. For Chun Yu, this was the first desire she was born with, called seeking knowledge. Thousands of years later, she understood what people said, how to pretend to be human, and seemed to understand what "human cunning" was, but she still didn't understand what human beings were and how they were different from herself. Gradually, she got tired of being in this world, and the desire for knowledge that she was born with seemed to be slowly disappearing. Until one day, something claiming to be a system came to her and asked her if she was willing to go to other dimensions... "Our goal is to balance luck! Maintain the plane!" "Hey, host, why did you save another villain?" "He also has a lot of desire... He wants to eat." However, Hong Yu is not a freeloader. Of course she will use resources to exchange for it. This is a mission anyway, isn't it? While traveling through the planes again and again, she was searching for where she came from, where she was going, and what... The human heart was. (It is tentatively expected that many villains will be rescued, and they will have a good impression of the heroine but will not increase their love, so they can eat it on their own)
