Just read the following passage 233333:
The young writer Li Su often dreams of a figure wearing a yellow shirt playing the guqin from behind. Then by chance, he comes to Qinchuan, a place he often visits in his dreams, where he meets a young girl named Ashue and gets a jade stone in Qinchuan, whose real name is Yuheng. One night, a soul appeared in Yuheng, which was the person he often dreamed about in his dreams. That person's name was Ouyang Shaogong. After meeting Shaogong, Li Su felt very kind and heart-to-heart. After that, every night I dreamed about the past, remembering Ouyang Shaogong and the battle at Gonggong Mountain. That day, both he and Shao Gong were supposed to have lost their souls. Shao Gong used his own soul to fill Tu Su's vacancy at the last moment, so that Tu Su could be reincarnated. The remaining souls stayed in Yuheng, waiting for Tu Su.
