Everyone is trapped in a dormitory survival instance. Chen Mo unexpectedly obtains exclusive information from the administrator, allowing him to gather supplies in advance and craft equipment. While other players panic and struggle to escape, he unlocks a dimensional backpack and various crafting blueprints to reinforce his dormitory. When zombies and mutated monsters attack at night, he relies on his skills and talismans to hunt them and level up. Along the way, he teams up with Cao Qingqing. He must also beware of looting players such as Brother Fei, explore the library and underground secret realms for powerful weapons, and face threats from veteran players who suddenly arrive. Growing stronger step by step, he defends his shelter and battles the instance's final boss.
