Upside-Down Ghost House

Su Linxiao, Wei Wei, and Lu Li check into the viral 414 room, which is haunted. Su Linxiao uncovers a dead body possession scheme, but the two others refuse to believe. After connecting to an inverted WiFi, strange events occur frequently, and Wei Wei is possessed by the male landlord Chen Zhiyong's ghost. Su Linxiao attempts to resolve the situation using her grandmother's Yin-Yang Mystical Record but fails, only to discover that the red-clad female ghost is actually a victim secretly helping them. The three endure inverted yin and yang, time reversal, and spatial loops, and finally, with the female ghost's help, destroy the formation, scatter the male ghost, and successfully escape. In the end, it is revealed that everything was a VR script murder game; the three receive an S-level pass, but eerie traces remain in reality, which is terrifying upon reflection.
