How Did I Become a Boss When I Wanted to Survive in the Back Room?

In 2099, many humans on the ground disappeared inexplicably. And they were transported to a space called the back room, which contained various unknown monsters. These people were the first people to explore the back room. Ye Chen, who was in class at school, was teleported to the back room because he fell asleep in class. He awakened the infinite supply system in the back room, hoarded supplies and explored the back room. Admit members, form an organization, and provide shelter for those who follow. (Adapted from the back room, part of the back room, this is another space called the back room that is equivalent to the back room but not the back room)
