An overworked office worker, Lin Xiaoman, dies suddenly from working overtime and finds herself trapped in an endless series of terrifying trial dungeons. By chance, she awakens the ability to understand insect language and recruits four deadly creatures: a centipede, a spider, a scorpion, and a little silver-scaled snake. From an abandoned psychiatric hospital to a mysterious island and a horrifying orphanage, every dungeon is filled with deadly traps and survival rules that mix truth with lies. The mad researcher Chen Jing conducts human experiments across multiple dungeons, regarding Lin Xiaoman as the once-in-thirty-years perfect test subject, Number 07. Cleverly exploiting loopholes in the rules, Lin Xiaoman commands countless insects to expose the conspiracy. Together with the wealthy heir Lu Ze, the official team captain Du, and others, she storms the underground experimental base, earns millions of points, and builds a prosperous new life.
