This is a pseudo-Nirvana in Fire fanfic. After reading "Nirvana in Fire", the stupid author cried 5678 times. He felt sorry for Lin Shu, but he also felt that if he had not become Mei Changsu, there would be no "Nirvana in Fire", so. . . . . You understand.
This is a novel in which the female protagonist travels through Langya Bang. She just feels sorry for Chang Su, but the male protagonist is not Chang Su.
