Yunyi did it on purpose. If Wu Bingjie dares make a sound, he won't get off easy today.
Wu Bingjie probably realized this, so he chose to endure quietly instead of reacting, but in his heart he was thinking: Just you wait.
But how could Yunyi just let him go? After all, this was Hua'an Farm Reclamation's clinic, where members of the Agricultural Reclamation Group received subsidies for medical visits, but people from nearby villages had to pay for treatments out of their own pockets.
Although keeping him here was very unsettling, seeing him suffer more bitterness and pay extra medical fees was still quite satisfying.
So when it came to stitching the wound, the matter of administering anesthesia wasn't mentioned.
Yunyi directed Kong Jiaqiao to help him treat the wound, then prepared to stitch it up herself.
This terrified Wu Bingjie: "Aren't you going to use anesthesia?"
