Hengcheng's domestic water is well water, and every household has water storage pottery. However, the water storage pottery in the common people's home is obviously too small.

In the end, the water storage pottery in the city Lord's mansion was moved out, but it was not very big. At most, it was the same size as the stainless steel bucket of the world where Chen Hui came.

Fortunately, the quantity is enough. There are six such pottery in the whole city Lord's mansion, all of which are used by Chen Hui.

The six potteries were overhead in the open space of the city master's mansion, and the fire was built underneath.

Some unused herbs were picked out by Chen Hui and put on one side.

Then, Chen Hui asked the four Shui civilians to put the same medicine into three water storage containers.

Chen Hui once taught them this prescription. The herbs used are bupleurum, Scutellaria baicalensis, ephedra, fried almonds, honeysuckle, Forsythia suspense, burdock, notopterygium, Maolu root and raw licorice.

"Is there any doubt?" Chen Hui asked when the four of them were adding herbs.

"The prescription is Xuanfei decoction. It's just right!" One of them answered immediately.

At this time, Chen Hui asked: "what is the main symptom of Xuanfei Decoction acupuncture?"

"Main symptoms: fever, aversion to cold, sore throat, headache, sore muscles and joints, shortness of breath, cough, less phlegm, white fur." The guy replied without hesitation.

Chen Hui nodded with satisfaction, looked at the other and asked, "what's the pathogenesis?"

"The pathogenesis of the disease is that the toxin and evil attack the lung Wei, causing the lung Wei to accumulate evil and the lung to lose its circulation." The one asked immediately bowed to Chen Hui and answered.

There is no doubt that Chen Hui took advantage of this incident to make a little assessment of them.

Chen Hui nodded again, then looked at the third one and asked, "what is the medical theory?"

"Clearing away heat and toxin, dispersing lung and removing pathogenic factors." The third answered immediately.

Chen Hui let out a "well", turned to the fourth and youngest one, and asked, "do you have any questions when you repeatedly look at the other three pots just now?"

When Chen Hui asked the first three questions, they were all about prescriptions and the diseases he was treating. When he asked the fourth guy, he asked a irrelevant question.

At this time, in front of the black emperor and the big Wizard of the Shui nationality, he was the youngest of the four. He was estimated to be 15 or 16 years old. Hearing Chen Hui's words, I didn't dare to say it.

"After you have learned something, you want to treat the common people of the Shui nationality. In the future, you will often see high-level warriors and Witches of the Shui nationality, including the great wizard of the Shui nationality and the black emperor of the Shui nationality. If you can't speak in front of them, how can you treat people?" Chen Hui said in a deep voice: "to learn this method of treating diseases is to face life and death. If you learn it well, you will be a good doctor for treating diseases. If you don't learn it well, you will be a quack for killing people!"

"Yes, sir!" After hearing Chen Hui's words, the young man took a deep breath and said, "I see the three pots are empty, but the herbs selected by Mr. Chen are still enough for Xuanfei decoction, so I wonder if we need other different prescriptions!"

Chen Hui showed a happy smile on his face and nodded his head with satisfaction. He began to ask three questions. According to what he said, he put herbs into the pottery pot, but he didn't have any doubts. This is of course due to their short learning time, but there are also problems about their understanding.

Or it can be said that although they are smart, they are not as smart as this young man.

To be fair, all the people of the five ethnic groups who study medicine are smart enough. In this month, Chen Hui taught them many prescriptions. From the previous answers of the three Shui civilians, we can see that they study very hard. They all remember the prescriptions that Chen Hui taught them.

But there are some differences between cleverness and cleverness. This young man's cleverness is not only reflected in his hard work, but also in other aspects. Seeing that the other three pots have not added the same medicinal materials, and the selected medicinal materials are still enough for the use of Xuanfei decoction, his doubts show that he observes in detail.

"Satisfy your curiosity and solve your doubts." Chen Hui light said: "the other three pots, need to put medicine is Fangfeng, Schizonepeta tenuifolia, notopterygium, Angelica pubescens, Peucedanum, Cimicifuga, kudzu, radix paeoniae rubra, Platycodon grandiflorum, Ligusticum chuanxiong, Angelica dahurica, mint, burdock, licorice, bupleurum."

Although Chen Hui didn't name the prescription, he did name the medicinal materials used in it. Obviously, he wanted them to add medicinal materials to the three pots.

The four guys immediately began to put herbs into the remaining three pots.

Chen Hui said at this time: "this prescription is called Baidu powder. I wrote it down!"

Four people in the addition of medicinal materials at the same time, the chorus should be!

"This Hengcheng event is an epidemic, not an ordinary disease." Chen Hui continued: "this point should be determined at the beginning, because illness is a personal illness, but thousands of civilians in Hengcheng fall ill. This is not just a disease. The pathogenesis of Xuanfei decoction is that toxic pathogens attack Feiwei, causing Feiwei to accumulate pathogenic factors, and the lung is not xuanjiang."

Chen Hui pointed to the three pots of Xuanfei Decoction and said, "it's true that the symptoms are right, but the pathogenic factors of the disease are not in the lungs. They are caused by an epidemic disease and then attack the lung Wei. Therefore, we should use Baidu powder to thoroughly remove the pathogenic factors in the body. Only by doing so can we cure all the civilians in Hengcheng."

After a pause, Chen Hui said: "although the two prescriptions need to be taken in two ways, they can be divided into different orders. Do you think about it, should you take Xuanfei decoction or Baidu powder first? Answer me when you've finished adding herbs! "

After a short time, the medicinal materials of Baidu powder were added up.

The four guys also gave their own answers.

The four guys tied, and the two agreed, as opposed to the other two.

It's not surprising that this happens.

Chen Hui nodded and said, "you should take Xuanfei Decoction first and then Baidu powder. The toxin has attacked Feiwei and made the patient short of breath, which is likely to develop more seriously. Therefore, treat the exterior first and then the root cause! What you two think is to cut corners from the bottom. It's a common method, but you need to distinguish priorities and write them down! "

The two guys who gave the wrong answer agreed to speak out immediately.

Chen Hui also said at this time: "when you study medicine, you should pay attention to the details. The observation of the details should be applied to all aspects. You study very hard and you are smart enough, but you lack the observation of the details. I asked you to take Xuanfei Decoction first and then Baidu powder. In fact, it is obvious that you should take Xuanfei Decoction first and then Baidu powder, It's just that you don't have enough details to observe. The Xuanfei decoction that you'd better boil first will be better. Naturally, you need to take it first! "
