The neck is located closer to the head and also closer to the torso.

Sometimes the diagnostic results will be more accurate, but as time goes by, few people know how to take the pulse at the neck.

Sheng Kangning has identified a location, but further confirmation is needed.

Sheng Kangning stretched out his hand and placed his fingers on Yang Hui's carotid artery. He frowned slightly and felt carefully. At this moment, there was a very slight sound and Sheng Kangning's hand was grabbed by someone.

Sheng Kangning raised his eyes and met Yang Hui's gaze.

When Yang Hui saw that it was Sheng Kangning, the initial vigilance in his eyes immediately turned into joy.

"Why are you here?"

Sheng Kangning patted Yang Hui's hand: "Let go, I'm checking your pulse!"

Yang Hui laughed: "You touch my neck to diagnose my pulse? Are you?"

Sheng Kangning frowned and was about to argue with him when he saw Yang Hui roll his eyes and faint again.

He didn't finish his words.

Fortunately, Sheng Kangning finally confirmed the location.

Yang Hui's sudden awakening and sudden coma had no effect on Sheng Kangning. Sheng Kangning calmly took out the silver needle that had been disinfected before.

The next step was to give Yang Hui acupuncture to force out the blood clots in his head.

Sheng Kangning's set of silver needles is an heirloom of the Ling family.

It has been passed down in the Ling family for hundreds of years.

It’s the old nine needles.

The old nine needles are divided into filiform needles, short needles, long needles, etc. according to the length, thickness and thickness of the needles.

What Sheng Kangning is going to use this time is filiform needles, which are very thin, as thin as a hair.

Sheng Kangning's hands were steady and quick when he inserted the needle.

In just one breath, nine needles were inserted.

After a few breaths, Sheng Kangning pinched the first needle and pulled it out.

As the silver needle was pulled out, a tiny drop of blood oozed out.

Next, every time Sheng Kangning pulled out a needle, a tiny drop of blood oozed out.

This scene fell into Zhou Bowen's eyes.
