Ning had locked the door from the inside and asked the man to bite on the corner of the pillow. After that, Ning started massaging.
The man seemed to have gotten into a small accident after which he started to stop feeling his lower body. It started off numb and soon he couldn't move it at all.
From what Ning could tell, the man had most of the nerves responsible for his lower body trapped inside his different vertebra. So, the signal to and from his legs was cut off.
Ning was trying to massage his body such that he would hit the different vertebra and have them separate themselves. Opening up the vertebra would cause intense pain, but he didn't have anything for anesthesia, so the man would have to suffer a bit.
"ARGGG" the man screamed for a total of 5 minutes as Ning continuously used his 10 Fingers Heavenly Massage technique on the old man.
