Yimeng people are a group that is free from various worlds and obtains rewards by exchanging dreams. Although it looks quite high-class, in fact, in the entire void world, when mentioning Yi Mengren, the word "poor" comes to everyone's mind. Even the tall and similar-looking Guimeng Tower where the Yi Meng people lived was chosen by the unscrupulous boss as a base just because it had a small area and was cheap.
Simon and Baili are one of the poor Yi Meng people who were sent into various worlds by their unscrupulous bosses to complete tasks in the name of cultural exchanges. The intentions of the unscrupulous bosses are still unknown.
