Mo Ni was hungry and playing games all night at home when a strange knock on the door suddenly sounded in the corridor. When I opened the door, there was no one there. What? Ghost knocking on the door? Impossible, absolutely impossible! The delivery boy must be playing hide and seek with him! Just wait, I'm coming to catch you! Mo Ni started wandering in the corridor: "I'm so hungry, I'm starved to death~" Also attached: What the hell is this system that appears due to sprained feet!
