After deciphering the Tor cipher text from ten years ago, the Seventh Research Group discovered an isolated island that was completely disconnected from a technologically advanced society. On an isolated island far away from the hustle and bustle of the world, the effectiveness of all precision electronic equipment is greatly reduced. Even the humanoid weapons that scientists are most proud of cannot be used normally. In order to find out the truth about the isolated island, the top management sent a special force directly under the cabinet to the island and launched a carpet exploration. The ecological environment of the isolated island is strange, with zombies and evil spirits emerging one after another, and a vampire was even found by a special soldier. A vampire wakes up from the coffin: "Who are you?" A special soldier: "..." I just want to ask who you are!
