Xiao Yifei's injury was very severe. He only woke up after 16 hours of sleep. When he slowly opened his eyes and hadn't grasped what had happened to him, the nurse taking care of him said, "Doctor Xiao, you finally woke up. You scared me to death all day and night. This is the first time I've seen a doctor so exhausted after surgery."
Xiao Yifei listened to the nurse babbling about something, but he didn't hear a single word she said. His head hurt so much it felt like it was about to explode, and he clearly felt his blood vessels pounding fiercely. He wanted to sit up, but suddenly realized he couldn't muster any strength in his arm; he felt like his body didn't belong to him.
The nurse came over to help him sit up, but he gently shook his head and refused her offer. He didn't want anyone to see how weak he was now.
So he asked the nurse to buy him some food, sending her out of the room temporarily.
