Elder Wang, with a chuckle, stroked his beard and immediately took out a silver needle to demonstrate his Wang Family's "Nine Dragons Divine Needles" before Lin Dong.
There are a total of nine needles in the Nine Dragons Divine Needles, each with many variations, though they are not as complex as the Taiyi Yin-Yang Divine Needle.
But it is still an extremely profound acupuncture technique!
Once Lin Dong learns it, he can use the Nine Dragons Divine Needles to treat ordinary patients in the future.
One advantage the Nine Dragons Divine Needles have over the Taiyi Yin-Yang Divine Needle is that they do not require the use of inner Qi.
For Lin Dong, it would practically be without any consumption.
If he were to treat many patients, say a hundred in one day, Lin Dong would be exhausted if he used the Taiyi Yin-Yang Divine Needle.
