Ling Ran massaged the elderly one after another, his touch becoming more fluid as he continued.
He was already familiar with using the standard movements to perform tasks in the operating theater. The same applied to performing the chiropractic manipulation for the cervical spine[1].
Using the correct posture to perform the massage would not cause the person doing it to feel overly exhausted. The intensity of performing chiropractic manipulation repeatedly was almost similar to that of performing surgery.
While in the operating theater, Ling Ran was a man who could continuously hold himself in one position for half an hour. He was even capable of performing fifteen hours of surgery in a day while maintaining one single posture.
Of course, under normal circumstances, performing surgeries for eleven to twelve hours straight was comparably much healthier than performing surgeries for fifteen hours.
