Underworld Elevator: Game of Death

The protagonist, Chen Mo, is a 35-year-old courier. He has a frail old mother, a virtuous wife and a pair of young daughters. He has a 30-year mortgage and still adheres to family responsibilities under the pressure of life. During a heavy rainstorm, he mistakenly entered a malfunctioning elevator in an old office building. The elevator plummeted to the negative 2nd floor, the "Yellow Spring Floor," and he stepped into a strange space on the 18th floor. Each floor corresponds to a different terrifying alien environment and a test of human nature. Only by clearing the floors step by step and reaching the 18th floor can he find the way home. His companions are all ordinary people who were accidentally involved in the elevator. While ghosts are around, the greed and betrayal of the human heart are more deadly.
