Everyone inside the room sat watching but remained silent as Ji Yang stepped forward and placed his hand on the old man's head.
The old man didn't object to his action and merely glanced at him.
Once his hand touched the other's head, Ji Yang began to sense his breath.
As the breaths made contact, Ji Yang found he could clearly feel the condition inside the man's body.
Stroke, in fact, is a situation where evil qi invades the body.
Ji Yang quickly discovered a dense presence of evil qi within the old man.
What is described as evil qi by doctors is simply a kind of qi to a cultivator. However, most people cannot resolve it.
Even Ji Yang had studied that many cases of poisoning were nothing more than the body's inability to withstand that particular kind of energy. If one could withstand it, even poison could turn into inner qi.
