Lin Fan felt a chill run down his spine, but Zi Xue had put the gag back into his mouth after removing her finger.
So even if he wanted to say something, there was nothing he could do.
He could only watch as Zi Xue brought the scalpel down over his arm and made the first incision.
Since she hadn't given him any anesthetic like in a normal operation, the full pain of being cut with the scalpel hit him. He endured it at first, but the way that she continued cutting him filled him with more and more pain until his mind had no choice but to completely numb itself.
In his daze, he turned his head to look at what she was doing.
She had made one quick cut at first, going lengthwise across his arm. She had done it in such a way that it avoided the major blood veins in his arm, so there was only a mild amount of blood that came out.
This was not something that could be done unless one had a deep understanding of human anatomy and was very skilled with a scalpel.
