I Just Wanted to Survive the Backrooms, So How Did I Become a Big Shot?

In 2099, people are mysteriously disappearing in huge numbers from all over the world. They are transported to a space called the Backrooms, where all kinds of unknown monsters lurk. These people become the first explorers of the Backrooms. Ye Chen is in class at school when he dozes off and is transported to the Backrooms. There, he awakens the Infinite Supplies System and stockpiles provisions as he explores. He recruits members, establishes an organization, and provides shelter for those who come after him. (Adapted from the Backrooms. Some elements are drawn from the Backrooms. This is another space called the Backrooms, similar to but not actually the Backrooms.)
