To fully heal Elder Liu's legs was indeed a formidable challenge for Fang Yi, even to the point of seeming like a fool's dream.
Yet Fang Yi found it very challenging. If one attempt didn't work, then he would try several more times, and Fang Yi planned to adopt a long-term strategy, slowly treating Elder Liu's legs.
After all, Elder Liu had endured ten years; what was a moment more?
As he inserted the silver needles one by one into Elder Liu's legs, Fang Yi exhaled a breath and also sighed in relief.
Just now, Fang Yi had manipulated the needles with True Qi, and precision was absolutely critical—deviation was not an option, or all his efforts would have been wasted.
Needle insertion wasn't something to be taken lightly; it required meticulous precision, which was why Fang Yi was so serious and careful.
Looking at the silver needles stuck into Elder Liu's legs, Fang Yi thought that this set of needles was ruined and that he must find time to craft another set.
