Honestly, it was not that the doctors and nurses of the medical center liked spectating, but that after the arrival of the Trinity Institute group, the pressure on them was suddenly relieved. Everyone heard the Trinity Institute was really fast at treating their patients, and the operations were even performed in a basic operating room that was not sterile.
When the doctors heard about this, they found it a little incredulous. How could the surgeries be performed in an unsanitary environment? Wouldn't the patients suffer from complications?
But when they went to check on the patients in the wards, many of the doctors realized the patients were actually recovering very well. Some of the patients were actually able to sit up in bed and chat with others after being operated on just a few hours before.
