Since Xue Qianyu was already engaged to Gu Nian, he could be considered half a member of the Gu family. Therefore, grandma Gu and Gu shouxin did not ask him to leave.
Grandma Gu told her what she knew.
Back then, her parents eloped and left Fuzhou. Her mother had a difficult labor when giving birth and died in the end. Her father took her to the village at the crossroads.
Her father didn't know her mother's true identity, only her name. At that time, her father was only the son of a tea merchant in Fuzhou, so how could he know about the kingdom of goddess? so, he didn't suspect much.
Therefore, the father and daughter had always thought that her mother had only given birth to one child and had died in childbirth.
As for the corpse, it must have been a fake one made by the people from the goddess Kingdom who had come to find her mother!
