Department Chief Kong's surgery was neither fast nor slow. His skill level was so high that he could not slow down even if he wanted to.
Perhaps in the eyes of others, Department Chief Kong's skill level was very high. However, in Zheng Ren's eyes, the surgery he performed could only be considered average.
That was a difference in the order of magnitude. It was not something that could be made up with years of surgical experience.
Even if surgical experience was compared, Zheng Ren had more time than Department Chief Kong to perform high-level surgeries in the operating theater without rest or sleep.
However, Zheng Ren just watched quietly. Department Chief Kong's surgery was not a problem and more than enough to complete the job. Zheng Ren would not jump out there and then just to show off his skills and suppress an old chief who loved and cared for him.
