What's more, a few years ago, Ren Xian had a serious illness, and when all treatment techniques didn't work, Han Tongshan took him to Han's house and personally went to the clinic to help him rejuvenate his hands.

It was also during those days of living in the Han family that Ren Chen had a deep understanding of the Han family's medical skills, and happened to see a rumored exchange transfusion.

However, in Ren Chen's medical philosophy, this kind of behavior of using other people's essence and blood to improve one's own physique is undoubtedly harmful to others and self-interested, and extremely immoral behavior, which is despised by the medical profession.

So after Han Tongshan argued a few words, because the two disagreed, Ren Yan left the Han family in a bad mood and returned to Ren'an Pharmacy.

Since then, the two have been strangers, and Ren Yan has never seen Han Tongshan again, not even a phone call.

Until today, when Han Tongshan was dying, he actually thought of Ren Chen, which made him unexpected, and even a little flattered.

Han Tongshan had a life-saving grace to Ren Yan back then, although the two stopped contacting each other later, but Ren Yan has always kept this in mind, and now he finally has the opportunity to repay the favor, and he is ready to go all out.

However, when Ren Yi asked Han Tongshan to be carried into his consultation room, after a careful diagnosis, the sweat on his sideburns came down.

It is said that doctors do not treat themselves, and no matter how much ability a doctor has, when he diagnoses and treats himself, it is inevitable that there will be a situation where the authorities are confused.

When treating oneself or one's family, they often have more concerns, worrying that a certain drug is harmful or toxic, and the taste of the medicine is changed again and again, and the final prescription is either not effective in correcting or inconsistent with the four sexes, so that the drug power is greatly reduced, and the efficacy is naturally poorer.

Actually, this is not the only reason.

A smart doctor often understands and pays more attention to his body than the average person, and also knows how to regulate it daily, so he usually lives longer.

And once they get sick, it must be a serious illness, serious illness and advanced age, even if the superb medical skills, most of them are unable to return to heaven, which also creates the origin of doctors who do not treat themselves.

Therefore, Ren Xi believed that Han Tongshan must have diagnosed and treated himself during his illness, but in the end he had little effect, so he pinned his hope on Ren Chen.

However, Ren Yan found that Han Tongshan's body was extremely weak at present, and the muscles of his whole body were in a tense state, this symptom he had never seen in the past, and he wanted to rescue, but he didn't know where to start.

This is like a fortress with an empty interior and an extremely strong outer wall, even if the enemy can't get in, his own reinforcements can't get in, and if it continues to wear down like this, even if the enemy doesn't attack again, the fortress will automatically lose its combat effectiveness and become a lifeless ornament in a short time.

According to Ren Chen's diagnosis, with Han Tongshan's current physical condition, it can only last for three days at most, and if the medicinal properties cannot enter the internal organs within three days, then I am afraid that there will be no surgery.

Subsequently, Ren Yan also tried some techniques, such as acupuncture, decoction, qigong, etc., but even if he took out what he had learned in his life, it still didn't work on Han Tongshan, and he was so anxious that he thought of Lin Yun.

In the phone call with Yang Yingxuan, Ren Xian just told her that this patient is very important and is likely to affect the development prospects of the entire Ren'an Pharmacy, which caused Yang Yingxuan to be restless, and she didn't know which big man was coming, which would make her Grandpa Ren nervous to this extent.

And when she learned that the patient was Han Tongshan, Yang Yingxuan's mood became more complicated.

On the one hand, having been with Lin Yun and Ouyang Yueling for so long, Yang Yingxuan also had a certain understanding of the martial arts family, especially when the Fang family encountered all kinds of troubles, she also had a trace of resistance to the martial arts family psychologically, worried that the Yang family would also repeat the mistakes of the past.

On the other hand, with Han Tongshan's high reputation in the medical community, if Ringan Pharmacy can cure his illness, then Ringan Pharmacy must be famous, which will be more effective than any advertisement.

In such a dilemma, in the final analysis, there is only one focus, that is, how to cure Han Tongshan's disease, and now the life and death of this old man have been firmly tied to the prospect of Ren'an Pharmacy.

Thinking of this, Yang Yingxuan couldn't help but set her eyes on Lin Yun, if even Ren Yi couldn't do anything about it, could Lin Yun do it?

After listening to Ren Yan's narration, Lin Yun also looked solemn, he knew Han Tongshan's current illness, the problem was that he wanted to cure this disease, but it was not so easy to do.

"Teacher Ren, can you take me to see the patient?" Lin Yun asked quietly.

"Of course, please come with the old man." After Ren Yan finished speaking, he led Lin Yun and Yang Yingxuan through the hall and came to an independent consultation room at the back.

At present, those family members of the Han family have been temporarily invited out of the Ren'an Pharmacy on the grounds of not disturbing their treatment, and Han Tongshan is the only one in the small consultation room, lying on the hospital bed silently.

Lin Yun stepped forward, first looked at Han Tongshan's pupils, and then checked his pulse, as Ren Wei described, Han Tongshan seemed to be always on guard, his muscles were tense to the limit, so that the golden needle couldn't penetrate it.

Lin Yun stood beside the hospital bed and observed for a while, then suddenly asked, "Teacher Ren, do you know subconscious self-protection?" ”

Ren was stunned and nodded noncommittally, although medical psychology is not his specialty, but as a doctor, he still knows a little bit.

"When the mind is greatly stimulated, the self-subconscious mind as a human being will trigger a defensive function of self-protection in order to seek a sense of psychological balance." Lin Yun explained slowly, but Ren Yi didn't understand what this had to do with Han Tongshan's current condition.

"Old Man Han is a person who is proficient in Western medicine, and he must know what methods should be used to protect himself when his body encounters great danger." Lin Yun continued.

"You mean, Han Tongshan used his subconscious mind to protect his body and use it to buy time for treatment?" Ren asked hesitantly.

"Things may not be as simple as we think."

Lin Yun said, gently breaking Han Tongshan's lips, only to see that the teeth inside were tightly locked, just like the muscles in his body, which could not be invaded by external forces.

Then, Lin Yun took out a silver needle, carefully pierced it between Han Tongshan's teeth, and after penetrating to a certain extent, he paused for a moment before taking it out again.

At this time, look at the silver needle, it is still shining silver, and there is no sign of blackening.

"You suspect he's poisoned?" Ren Yan knew very well what this move meant, and immediately asked.

"Possibly." Lin Yun replied lightly.

"But only with the words of the silver needle......" Ren stopped talking.

Silver needle drug testing is only a practice in ancient times, mainly using arsenic trioxide in arsenic, which will react with silver to produce black arsenide principle, which is used to test poison.

However, the limitations of the silver needle test are very large, some items do not contain poison, but contain a lot of sulfur, such as egg yolk, and the silver needle will turn black when inserted.

On the contrary, some are very poisonous, but do not contain sulfur, such as mushrooms, nitrites, pesticides, rat poison, cyanide, etc., and silver needles will not react black when they come into contact with them.

But in Ren Chen's opinion, such a simple truth, Lin Yun should know it well, it is impossible to make such a low-level mistake, isn't what he did just now to test the poison?

I saw Lin Yun holding the silver needle, came to the table on the side, and took out a ginger-like medicinal herb from his backpack, cut off a piece, and spread it on the table.

After the piece of medicinal herb was in full contact with the air, Lin Yun pasted the silver needle on the surface of the medicinal herb.

In just an instant, the surface of the originally tender yellow medicinal herbs was suddenly printed with a blood red, the red was bright like blood, shocking, and there was a pungent fishy smell in the air.

"What's going on?" Ren Yan and Yang Yingxuan covered their noses at the same time and widened their eyes.

Ren Yan has been a traditional Chinese medicine practitioner all his life, and he has never seen such a strange scene, not to mention that he doesn't understand how this phenomenon is formed, even the kind of medicinal material in Lin Yun's hand, he doesn't know its name, and a feeling of shame immediately wells up in his heart.

"Sure enough, as I thought, Old Man Han was poisoned." Lin Yun didn't rush to explain, but muttered to himself.

"Poisoned? As a dignified Han family, he would be poisoned? Ren was shocked and said that this result was not only for him, but also for all doctors in the country to believe it.

"Refining the poison fruit will not deceive people, judging from the results of the poison test just now, the toxicity remaining in Old Man Han's body is still very strong, presumably because he can't remove the toxicity in his body in a short period of time, so he chose to use the method of self-protection and let people send him to Ren'an Pharmacy." Lin Yun said after wrapping the piece of medicinal herb in paper and throwing it into the trash.

Although he didn't know what the poison refining fruit in Lin Yun's mouth was, judging from his calm expression, he should be completely sure.

Ren Yan no longer doubted Lin Yun's judgment, and asked thoughtfully: "With Han Tongshan's status, who could poison him, and what poison could he deceive him?" ”

"Hmph, it goes without saying that it must be the closest person around him, so he didn't watch out." Yang Yingxuan snorted coldly and said, she has always been extremely disgusted with this kind of conspiracy.

"Even Xiao Xuan can see the problem, I don't think I need to explain it anymore, right?" Lin Yun said with a smile.

In the face of Lin Yun's undisguised IQ discrimination, Yang Yingxuan gave him a roll of the eyes very unceremoniously, and she was forced to be present with Ren Chen, but she still restrained herself and did not return the favor.

"No wonder he didn't dare to treat at home,
