Li Luo had a strange dream. In the dream, he was in a fog, and a strange ball of light floated beside him and said some strange words.Early in the morning, Li Luo brushed his teeth and suddenly saw the light ball behind him from the mirror, which scared him so much that he almost screamed.The light ball floated quietly behind him, like a ghost. After a while, Li Luo suppressed his heart, turned around and looked around. The roommates were all busy with their own affairs, and no one saw the light ball.
