An old locust tree in the town suddenly cracked. The crack was in the shape of a perfect five-pointed star, and silver light powder would flow out at night. Qingqing recorded this incident in her "Strange Occurrence Record Book".
The next day, a strange boy named Mark moved next door. He didn't know how to smile, and his eyes were as dark as a starless night sky. Qingqing discovered that Mark and her jar of "night sky-colored slime" that disappeared inexplicably had the same blue shimmer.
