I can heal him

After hearing the Old master, Old Lady was shocked. Her husband was almost rear-ended. If not for Qin Yan, he would have been injured severely. And everyone knows that it is not easy to heal in old age. Nobody knew when the Old Master would recover if he got injured.

Moreover, Qin Yan had also saved Old Master Xi's life by administering timely acupuncture to him. If not for her, maybe they would be in hospital instead of enjoying the delicacies here. 

Old Lady Xi's eyes welled up with tears as she realized how much Qin Yan has helped them. Overwhelmed by emotion, the old lady slowly made her way over to Qin Yan and took her hand in her own. She looked deeply into Qin Yan's eyes and said, "Thank you. Thank you for everything you've done for us, Yan Yan. I will forever be grateful to you."

Qin Yan shook her head, "Grandma, you don't need to thank me. If I was in grandpa's place, wouldn't he have saved me? We are family. If we don't protect each other, who will?"
