: An "unintentional" disappearance forced Lu Jingxuan and Yao Shiqing into a deep underground exploration well that no one dared to ask about. Every door in the cave seems to mock human intelligence: the moment food spoils, the direction ventilation betrays, the surveillance disguised as the sound of wind. What's even worse is that they find themselves being thrown into the game as "material" - leaving alive does not depend on luck, but only on the pretense of being more ruthless and more human. The secret of survival is hidden in the black humor, and every step to survive in a desperate situation is calculated just right.
