After Song Qingen returned to his hometown to attend his grandfather's funeral, a century-old evil ghost appeared in his family.
Song Qingen: Are you an evil ghost?
Yu Yuanbu (nodding): Yes.
Song Qingen: How many people have you harmed?
Yu Yuanbu: "Your uncle, your great-grandfather and your grandfather."
Song Qingen:......
Song Qingen: My grandfather lived to be ninety years old.
Yu Yuanbu:? So
Song Qingen: Evil ghosts are nothing more than that.
Yu Yuanbu: Anyone who has been dead for a hundred years and has not been reincarnated is considered an evil ghost.
Song Qingen:......
Intention: Every cause must have its effect
