He was the tail of the crane, and he did everything he wanted to do for himself, and finally he killed himself. Originally, this life was miserable, and it was over when it ended. Who knew that he would be reborn, and that would be it, and he would encounter Gu Ruoheng, his enemy from his previous life, and continue to be entangled with him.
