In exchange of godl (2)

"I am not the son of my mother," 

Murong Si's words caused even Yu Dong to raise her head, in fact, it happened so fast that she almost cracked her neck. 

"What—— Oww," Yu Dong winced as she cupped the back of her neck while Shen Li massaged her neck. The two of them looked at Murong Si who had dropped such a heavy bomb out of nowhere. Murong Si was not the biological son of Old Madam Murong. Then why was he living with the Murong family? 

'That greedy old hag doesn't look like someone who would take an Orphan child in her family and raise him for so long,' Yu Dong grimaced as she thought, one of her eyes was closed because of the sharp sting in her neck. 

Murong Si seemed to have realised what Yu Dong was thinking about and then explained to her, "I am the son of a woman with whom my father had an affair. My mother did not want the villagers to know that she had been cheated on, so she took me in but she does not have any feelings towards me."
