Go on, continue speaking

Shangguan Wanrong glanced at the both of them in surprise as she struggled to remember who they were. However, if they called her Martial Uncle, that meant that they belonged to Pill Sun Sect. 

Feng Jiu who was on the side slapped her forehead: "Oh, I forgot to tell you." She glanced at Chen Dao and Luo Heng and said in an apologetic voice: "I should have told you earlier, this is my mother."

"Wh, what?" Luo Heng looked at Feng Jiu in shock, and then at Shangguan Wanrong. He couldn't believe that Feng Jiu was Martial Uncle Shangguan's daughter. 

God, what relationship was this?

Chen Dao who had been listening on the side was a little surprised. So Shangguan Wanrong was Feng Jiu's mother? If so, then things made sense.
