Going in means death.
Fatty silently nodded. "The door you saw in the painting is probably the dormitory door the Doctor was looking for. We both guessed something bad would happen if that door was opened. The Doctor must have opened it…"
Then he was pulled through the door, but there was no bloodshed. No, there might be blood in the future, but it certainly won't be the Doctor's, Fatty thought.
At that moment, Chu Changge continued, "I suspect that the door is the boundary between the real world and this 'Vanishing Game'. Those who have played this game before have all disappeared, and no one has ever seen their bodies. So I suspect that the people who disappeared before were all pulled into this pixel game, through that door."
Of course, they were still alive when they were pulled into this pixel game, but once in, there was essentially only one path left: death. Later, the people who were pulled into the game became ghosts, continuing to draw subsequent players into the game.
