After accepting the ancient medical book and expressing his gratitude, Zhang Yuan lifted the red cloth covering Chen Yunshan's plate, revealing another medical book inside.

The content of this book is all about the art of diagnosis by observation. The copying time marked at the end of the page is the Yuan Dynasty, so it is also a handwritten copy.

Zhang Yuan now thinks that his diagnosis skills are still good enough.

After all, his spiritual perception was far beyond that of ordinary people, and he could clearly sense the direction of the body's meridians and breath.

Therefore, diagnosis by observation has become Zhang Yuan's strong point.

However, this book still contains many new and unique aspects regarding the art of diagnosis by observation.

Zhang Yuan was quite satisfied after just flipping through a few pages.

After receiving the two medical books, Zhang Yuan expressed his gratitude to Chen Guangrong and Chen Yunshan, father and son.

However, what the father and son prepared for Zhang Yuan was not only medical books, but also a large amount of collected Chinese medicinal materials.

After Zhang Yuan handed the medical skills to Heitao, more than 20 men in black came in.

Each of them was carrying two large suitcases in their hands. When they opened them, they were found to be filled with extremely precious Chinese medicinal materials.

Zhang Yuan picked up some at random and put it to his nose to smell it, and he knew that it was indeed a first-class medicine.

The price on the market is at least hundreds of thousands for a box. Ordinary people will never be able to get such high-grade medicinal materials in their lifetime. It is not something you can get just by wanting to.

Because some Chinese medicines have extremely strict requirements on their growing location and environment.

For example, some fire-natured medicinal herbs must grow near a crater to absorb the essence of the heaven, earth, sun, and moon, as well as the unique fire energy of the crater.

The Chinese medicine grown in such places is authentic and has excellent medicinal properties.

There are also some medicinal herbs with cold properties and tonic properties. They must grow on Changbai Mountain and endure the bitter cold all year round. Their medicinal properties are hundreds of times stronger than those of Chinese herbal medicines grown in greenhouses.

The medicinal properties of something are, on the one hand, affected by the medicinal materials themselves, but to a greater extent, they are affected by the environment.

Therefore, truly good medicines are not circulated and are extremely expensive.

After Zhang Yuan checked these medicinal herbs, he felt even happier.

Once again, I expressed my gratitude to Chen Guangrong and his son.

At this time, the door of the reception hall was pushed open again.

A middle-aged man in a wheelchair was pushed in. He looked very serious.

His cold and resolute face always shows seriousness and solemnity.

Zhang Yuan recognized him at a glance. Isn’t this Guo Qiming from the Guo family?

Why is he suddenly in a wheelchair?

He was a normal person, but now he looks a little unwell. This is a little different from the state that Guo Meiting described to herself.

After Guo Qiming came in, he looked straight at Zhang Yuan and said:

"Dr. Zhang, I have heard of your great name for a long time... You wanted to come to see me with my niece several times before, but I didn't see you. This is my fault. I want to apologize to you here."

Zhang Yuan quickly said:

"Uncle Qiming, you are too polite. We are all family. Weren't you fine before? Why are you suddenly in a wheelchair now?"

Guo Qiming sighed.

"Alas... most likely... I've also been poisoned. In fact, I've always felt that there's something wrong with my body."

"But the hospital in the family, including some very good doctors, and I even went to the Liu family's top medical institution for a physical examination, and there were no problems."

"I have had a lot of contact with Brother Li in the past two days, and I just realized that my condition is most likely a case of poisoning."

"I wanted to ask you to check my illness, but your condition seems a little dangerous right now, and you have been busy with your own things in recent days, so I didn't bother you."

"Now that you have finally finished your personal affairs, I think you should have time to help me check my body."

"As for medical books and Chinese herbal medicines, I have also asked the Guo family to go all out to search for them."

"My niece has already told me about this matter, and I have been working on it. I believe there will be results soon."

"Now, please help me take a look at what's going on. I want to know the final answer."

Zhang Yuan nodded silently.

He pulled a chair from the reception hall, sat opposite Guo Qiming, and began to take Guo Qiming's pulse.

Time passes by every second.

About 5 minutes later.

Zhang Yuan's eyes were filled with helplessness, and he said to Guo Qiming with certainty:

"Uncle Qiming, you are really a person with strong self-awareness... That's right, you are poisoned. The pain in your legs that makes you unable to stand is a sign of the poison taking effect."

"Well, I'll give you acupuncture first. The symptoms of your poison are in your legs, and they will be under control soon."

"It's not as complicated as the internal organs. After I finish the acupuncture, you can basically walk again."

When Guo Qiming heard this, an excitement that could not be described in words instantly appeared on his face.

He nodded repeatedly and said:

"Dr. Zhang, thank you, thank you so much..."

Zhang Yuan smiled and said, "You are too polite. We are all family."

Next, Zhang Yuan used the silver needles provided by Li Aiping to perform leg acupuncture on Guo Qiming on the spot.

In less than 20 minutes, the silver needles were put away again.

......

After the needle was removed, Guo Qiming's legs began to sweat, with tiny drops of black blood oozing out one after another.

These blood beads actually seeped out from the pores.

As the black blood seeped in, Guo Qiming's legs looked extremely scary because the skin was black and purple.

To people who don't know medical knowledge, Guo Qiming's legs looked like they were necrotic at this moment.

Especially the skin, it's really scary.

However, Guo Qiming felt his legs were warm, without the chilling pain he had felt before.

He tried to stand up slowly and took two steps. Surprisingly, there was no problem at all. Everything was normal and he could walk.

Guo Qiming was so excited that he couldn't express it in words.

He bowed deeply to Zhang Yuan.

Zhang Yuan smiled and clapped his hands and said:

"This is what I should do. Tomorrow... I will ask Guo Meiting to send you some medicine to regulate your body. You must drink this medicine according to my instructions to you at that time."

Guo Qiming nodded repeatedly:

"Okay, Dr. Zhang...um...I know you're not short of money now, but I still have to express my gratitude to you."

"Please keep this black card. You never know when it might come in handy. There's 20 million in it. I hope you don't mind it, Doctor Zhang."

Guo Qiming directly gave Zhang Yuan 20 million, which made Zhang Yuan laugh and cry.

We are all our own people, yet they are still so polite.

Zhang Yuan naturally chose to refuse politely.

But Guo Qiming was too enthusiastic. If Zhang Yuan didn't accept his 20 million black card, Guo Qiming would kneel on the ground and never get up.

Zhang Yuan really had no choice but to bite the bullet and take the 20 million from Guo Qiming.

Collect the money.

Li Aiping looked at Zhang Yuan very formally and said:

"Doctor Zhang, you can actually see that today, the three major families of Qingcheng City, the Li family, the Chen family, and the Guo family, have gathered here to discuss something with you."

"Our three families have decided...from now on, we will unite and each family will bring out their most powerful experts to provide all-round protection for you, Doctor Zhang, and we will resolutely prevent the person who poisoned you from persecuting you."

"You risked your life at any time to treat us, and your family was also threatened... You paid too much..."

"So, let's decide now and see where to place the masters from our three families so as to provide better protection."

"Dr. Zhang, what do you think?"
