Door World: I Can See Prompts

Overnight, all kinds of doors appeared on the earth. There are five doors that everyone must open and enter every day. No one knows what is behind the door. Just when Li Ran mustered up the courage to open the first door, a small text suddenly appeared in front of him. "Behind this door is an extremely hungry gray wolf. If I were you, I would never choose to open it." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
