Liu Buyan was dumbfounded when he heard that and immediately after, his expression turned ugly.
The weak lass right in front of him was extremely immodest. She returned the ridicule that he had sent to her just minutes ago.
Earlier he said "if she wanted to throw herself him, just tell him straight" and now her reply was "if you're not able to cure me, just tell me now", didn't this mean she was doubting his medical skill?
If this could be tolerated, then what else could not be!
In Liu Buyan's entire life, the one thing that he could not tolerate was someone doubting his medical skills!
