This time Yang Xiao performed acupuncture on Liu Uncle's son; it was an incredibly slow process.
Many needles were inserted, and each was left in place for a long time, requiring a complex and delicate technique of handling them.
Even with Yang Xiao's skill, he couldn't help but sweat profusely from his forehead, feeling mentally and physically exhausted.
One can only imagine, treating Liu Uncle's son's leg seemed simple in words, but it turned out to be extraordinarily complex in action.
And the reason he put it so lightly was probably just to prevent Liu Uncle from worrying too much, hoping to appear as calm and composed as possible to put Liu Uncle at ease.
It's worth mentioning that Liu Uncle's son was very strong.
Even though he underwent tremendous, almost inhuman pain during the procedure, he managed not to make a single sound.
He endured all the pain, even if it caused him to faint from it eventually.
