At this time, Liu Rui was completely unaware of what was happening outside after taking the drunken dream, so if Yun Fan was willing, no matter what he did to Liu Rui, Liu Rui would just be a fish on the chopping board for him to slaughter.

However, Yun Fan would not do anything to Liu Rui, all his attention was on the source qi, and as the source qi flowed into Liu Rui's body, the meridians around Liu Rui's body had clearly appeared in Yun Fan's heart.

Previously, whether it was in the illusion or the Spirit Beast Xuan, Yun Fan could not devote himself wholeheartedly, so the treatment of Liu Rui could only rely on his own experience to slowly repair the damaged meridians of Liu Rui's head using source qi. At this time, as Yun Fan immersed all his spiritual power in it, he could accurately repair and heal through Liu Rui's meridian diagram that appeared in his heart.

When Liu Rui's meridians all appeared clearly, Yun Fan couldn't help frowning, yesterday in the Spirit Beast Xuan, he had repaired all of Liu Rui's damaged meridians, the main purpose of coming here today is to discharge the residual poison he investigated, and in Liu Rui's meridians, there is no area showing the existence of residual poison, if you look at it from the meridians alone, there is no problem with Liu Rui at this time, which makes Yun Fan where to start.

According to the location of yesterday's memory, Yun Fan flowed the source qi to the area where the residual poison appeared before, and sure enough, at this time, there was no longer any residual poison here, if it wasn't for the slight detection of a trace of residual poison, Yun Fan even felt that he had misremembered the location.

Although the residual poison has disappeared, Yun Fan's expression has not relaxed in the slightest, he knew very well in his heart about Liu Rui's treatment yesterday, he only repaired Liu Rui's damaged meridians, and deliberately left the residual poison, waiting for it to be completely eradicated today, but he clearly didn't do anything, how could the residual poison dissipate by itself......

Yun Fan would not be naïve to think that the residual poison would slowly dissipate by itself, as for the Mingxin Qingluo Pill he gave Liu Rui, he knew how effective this thing was.

So since the residual poison will not disappear on its own, the only explanation can only be...... It's hidden......

With this judgment, the cloud

Fan can't help but feel a little tricky, maybe as Dafu said, what caused Liu Rui so much pain was not any residual poison, but the medicinal effect of the Divine Pill, but since it is a medicinal effect, there should also be areas and traces of the effect of the medicinal effect, but the area that can still perceive the problem yesterday is no different from the normal meridians today.

Thinking of this, a trace of sweat oozed from Yun Fan's forehead, because he came to a very bad conclusion, that is, the residual poison of the Shen Pill, which may only appear when Liu Rui's illness occurs, and when the condition subsides, the residual poison will recede, and finally it will seem as if it never existed.

Could it be that we must wait until the next time Liu Rui's condition attacks before we have the opportunity to be treated...... Yun Fan couldn't help but clench his fists, damn it! If that's the case, then wouldn't all these efforts he had made be in vain, and more importantly, what was his promise to Liu Rui, if he couldn't do it after all this time, what reason would he need to find to make him cooperate with him so much next time, and at that time, would he still believe in himself as much as he does now......

Yun Fan shook his head and dispelled all these bad thoughts, no! There must be a way, there must still be a way! If the master was here, what would he do if he encountered such a situation......

Yun Fan tried to calm his mind, imagining what kind of method Yuan Ping would choose to solve this kind of disease that he didn't know how to start.

Yuan Ping's earnest teachings continue to echo in the ears, in the face of those various incurable diseases, how Yuan Ping treated, these complex cases, most of which have reference significance, have been recorded by Yuan Ping in the Quartet Medical Dictionary, and there are many rare cases, Yuan Ping will also use them as stories to tell Yun Fan in his spare time.

"Master, have you ever encountered that kind of patient who can't find the cause?" Yun Fan recalled that he had such a conversation with Master.

"What do you mean by this question?" Yuan Ping twisted his beard lightly and asked with a smile, "As a doctor, looking at and hearing the method of asking questions, finding the cause of the disease is the way of a doctor. ”

"Hmm...... That is, sick

The patient is extremely painful, but after you diagnose it, you can't determine what caused it, what will you do?" Yun Fan asked mischievously, in his heart, although Master's medical skills were superb, he also wanted to see if there were any problems that Master couldn't solve.

"Oh, the patient is extremely painful, but I can't diagnose the cause......" Although Yun Fan asked a naughty question, deliberately trying to embarrass the master, Yuan Ping did not take Yun Fan's question as a joke, but thought about it very seriously, "Good question...... Good question......"

Yun Fan saw that the master had said two good questions in a row, so he began to think seriously, so he also quietly silenced and quietly waited for Yuan Ping's answer.

"The diseases in the world are ever-changing, but they are complex, and as doctors, we are definitely not a few who cannot diagnose the causes...... "But as the teacher often says, the practice of medicine is the accumulation of precipitation and learning, so in the face of undiagnosed causes, first of all, do not deny yourself, but believe that you can do it, because at this time you are the only reliance on the patient, if you deny yourself first, then the patient will also lose all hope......

"After that, we have to find out what happened to the patient, his past before the onset of the disease, the process of the onset of the disease, and the ...... after the onset of the disease," Yuan Ping's voice slowly appeared in Yun Fan's mind, "I still remember that the teacher once told you that everything in the Nine Realms is composed of qi, including the human body, no illness will come for no reason, and no illness will disappear for no reason, and the root of everything lies in qi...... If the qi is not right, the disease will be evil, and the qi will gradually calm down, then Taihe will come to ......"

No illness comes for no reason, and no illness goes away for no reason......

These two sentences kept echoing in Yun Fan's mind, looking at Liu Rui in front of him, Yun Fan seemed to know what he should do, the remaining medicinal effect of the Divine Pill, as long as Liu Rui's illness is not cured, it will not really disappear, even if he can't perceive its existence, but Yun Fan has already expected that it is hidden in Liu Rui's head meridians!
