Lin Xiaoman, an overworked corporate drone, suddenly dies from exhaustion and finds herself trapped in an endless series of terrifying survival trials. Unexpectedly, she awakens the ability to understand insect language. In her first dungeon, Qingshan Psychiatric Hospital, she uses snacks to recruit venomous insect allies, including centipedes and spiders, dismantles layers of fabricated rules, and exposes researcher Chen Jingzhi's conspiracy involving human experimentation. In subsequent island and orphanage dungeons, she meets wealthy heir Lu Ze, official team captain Du Yan, and timid Su Xiao. She recruits a Scorpion King, a silver-scaled little snake named 007, and other venomous creatures, gradually uncovering Chen Jingzhi's cross-dungeon experimental network. Finally, at the Happy Orphanage, she defeats Chen Jingzhi, whose obsession has consumed him, and earns the title of Lord of All Insects.
