Song Yuansheng grew up in New China under the red flag. He has received so many certificates as a "Three Good Student" and "Excellent League Member" since he was a child. He is an out-and-out atheist. But when he first entered the library, he saw a ghost.
To be precise, it was a male ghost wearing a white shirt and jeans, floating unscrupulously above the library and flying down from time to time to make faces in front of him.
Song Yuan, who had neither yin and yang eyes nor seen ghosts since he was a child, was not calm. Then the moment he saw the ghost's face, his "not calmness" reached its highest point.
