Wu Nanshan slowly opened a jade bottle. As the rich medicinal fragrance wafted out, a faint spiritual power overflowed from Wu Nanshan's body at the same time.
Under his control, a drop of emerald-green spirit medicine essence floated out of the jade bottle and slowly entered the space between Gu Xi's brows.
In the next moment, Gu Xi's entire body suddenly trembled.
The essence entered his body and under Wu Nanshan's control, seeped into Gu Xi's broken meridians. Then, it slowly spread toward the latter's limbs and bones.
Gu Xi only felt a cool sensation all over his body. It was as if his entire body was soaked in a medicinal pot.
However, what followed closely was a heart-wrenching pain!
If all of Gu Xi's meridians had been twisted into a rope, the treatment now was equivalent to slowly untying this rope.
One could imagine the pain!
