Hei Xiong and Xu Xiao You didn't disappoint Tang Wanwan with their task. Tang Wanwan couldn't show her face, so she taught Xu Xiao You the method of blood testing. Xu Xiao You, understanding medicine, grasped it right away when Tang Wanwan explained.
Fortunately, Hei Xiong was there. Although he quarreled a bit with Mrs. Gu, finally the blood testing was completed.
Gu Xinyu and Gu Xinwen could both give blood to Gu Yunzhi, but the required blood volume was substantial. It caused some concern.
When Gu Xinwen heard she had to give blood, she refused outright in public. "Why should I give my blood? You're all quacks. What if I die, who's going to pay for my life?"
Xu Xiao You, following Tang Wanwan's words, said: "According to ancient texts, it's not life-threatening for a person to normally draw a bowl of blood in a day. It just requires a few days of rest and some nutrition to recover."
"Nonsense, you're just seeking revenge."
