Gu Qingxue could not afford to use gas anesthesia yet, and she could not let Gong Lingyu see the whole process of the operation, so she had to give her a general anesthetic.
In addition, Gong Lingyu was weak, so the effect of the anesthetic was exceptionally good. According to her preliminary estimation, Gong Lingyu would need another four or two hours to wake up.
However, it was not a big deal. As long as she stayed by Gong Lingyu's side and paid attention to the situation, she would be safe.
Knock, knock.
At this moment, there was a knock on the door.
Gu Qingxue looked at the door and heard Miao Yin's respectful voice from outside, "Lady Gu, as you instructed, I've boiled a new hot water."
