Zhang Fan slept extremely well. He fell asleep around 1:00 p.m. and reached a deep state of sleep almost instantly. He slept all the way until 8:00 p.m. or so, reaching the point where he felt dizzy after finally waking up. Why had he slept so well? It was because he had performed too many surgeries, and also because his surgical assistants had been Wang Yanan, who was a young woman, or Xue Fei, who was rather unreliable.
