In just a few minutes, dozens of needles had been inserted by Yin Tian around Zhen Huayi's eyes.
Sweat was also beginning to bead on Yin Tian's forehead.
This was the secret technique passed on to him by his master.
Apart from this, there was no other way to restore Zhen Huayi's sight.
Some time passed and suddenly there was a knock at the door.
"Master, the medicine you asked me to grind is ready. Shall I bring it in now?"
"Yes."
Yin Tian responded loudly.
With a creak, the door to the operating room opened, and Doctor Hua came in holding a bowl.
In the bowl was a yellow powder, emitting a strong medicinal fragrance.
Doctor Hua carefully approached Yin Tian and handed over the bowl.
Yin Tian glanced at it and then nodded slightly, "Good, mix it with water to dampen it, then spread it on a gauze pad. We need to wrap Huayi's eyes with this medicine."
Doctor Hua did as instructed, holding the gauze, waiting on the side.
