Everyone’s support should be strong.

After Pharmacist Kong came over, he didn't say anything nonsense and asked directly: "How much does it cost to ask for a Master Xu's lecture coupon?"

The servant spread his palms, shook them in front of the pharmacist Kong, and said, "Five hundred taels of silver cannot be lost."

"Give me one." Pharmacist Kong said readily.

The servant was stunned. Since Zhang's mansion hung the banner out, Pharmacist Kong was the first person to pay for it without bargaining. He quickly took out a beautiful wooden sign prepared in advance, wrote a number on it with a brush, and asked, "Sir, are you a surname?"

"Kong." The pharmacist Kong said concisely.

The servant added the word "地" to the wooden sign, then dried the ink marks on the wooden sign, respectfully handed the wooden sign to Yaoshi Kong. The latter looked at it, carefully received the wooden sign in his arms, and then took out a silver note of 500 taels of silver and handed it to the servant.

Until the pharmacist Kong turned around and left, the servant was still in a dream. When his master set the price to 500 taels, he thought the master was crazy. He didn't expect that there were really rich people in the world who were willing to give out such a large sum of money and listen to others' lectures.

Isn’t it just like talking to people? Isn’t it scary?

The servant was puzzled.

Li Wenjun knew that the pharmacist Kong was a famous pharmacist in the city. Even he felt that Xu Yidan’s lectures were worth listening to, so there must be something good here, and perhaps there are things he needs. Many things in the world are gone after this village. If this is the opportunity he is waiting for, once he missed it, he would not know what the year of the Monkey and Horse Month will be waiting for next time.

Thinking of this, Li Wenjun no longer hesitated. He first found a secluded place, changed into a set of clothes, disguised it for a while, then returned to the door of the Zhang Mansion, took out a few gold pieces, and collected fifty taels of gold, and asked for a class coupon.

After getting the class ticket, he hurriedly left. If someone was jealous of him and was about to attack him, although he was not afraid, it would be a big and small trouble.

Perhaps Fengshou Town has been prosperous these days, with people everywhere, and the government has strengthened patrols and patrols, so it is difficult to find a place to attack. When Li Wenjun returned to Sun Baicao and his son, no one jumped out and blocked the road to rob him.

Li Wenjun asked about the situation of Sun Baicao and his son. Sun Baicao and his son were not idle today. They had a division of labor. Sun Jianing stayed behind, and Sun Baicao was outside inquiring about the market. The father and son cooperated to try to make the herbs they had accumulated for a long time and be able to sell them at a good price.

There was nothing to say all night. The next day, Li Wenjun rushed to Zhang's mansion a quarter of an hour in advance and showed his lecture voucher. The servant respectfully invited him in.

After entering the gate of Zhang's mansion, turn right, and in a corner of Zhang's mansion, there is a kind of elementary school. This was set up by Zhang Jianjie for his children, relatives, slaves, etc. All the expenses are the responsibility of the Zhang's mansion. There are only a dozen children here, but the elementary school school covers a large area, which is more than one acre.

Xu Yidan’s lecture location is here. Li Wenjun walked into the school. He was still dressed up when he asked for a class voucher yesterday. He looked like a young man in his thirties.

Li Wenjun thought he was not too late, but after entering the school, he found that the school was almost full. He didn't know that the fifty places determined by the Zhang family were sold out one day yesterday. Just this item, the Zhang family earned 25,000 taels of silver. In addition to the cost of hiring Xu Yidan, the Zhang family would have to make a lot of money.

Li Wenjun sat down in a not-so-obvious place and randomly looked at the dozens of people attending the class. Except for the Yaoshi Kong who was sitting in the front row, he knew, all the others were strangers to him. These people were discussing each other enthusiastically, and the topic basically revolved around Xu Yidan.

Li Wenjun was afraid that someone would talk to him, so he would show his timidity as soon as he opened his mouth, so he simply sat down and closed his eyes to rest. Sure enough, the person sitting next to him wanted to talk to him, but when he saw his appearance, he lost interest.

After a while, a middle-aged man in a private outfit accompanied a man in a Confucian robe into the school. The man who knew the man in a private outfit shouted, "Mr. Zhang is here."

The person who came was the owner of this house, Zhang Jianjie, the most powerful man in Fengshou Town. His face was filled with smiles, he clasped his fists, bowed to everyone, and said, "Everyone, Zhang is late, I have been waiting for you for a long time."

The man Zhang Jianjie accompanied was not smiling at all, with a stern face and expressionless face, as if someone owed him eight hundred yuan to pay.

After saying hello to everyone, Zhang Jianjie pointed to the man beside him and said, "Everyone, this is a famous doctor from the capital, known as Master Xu Yidan, who is known as the rejuvenation of the wonderful hands. This time, I am really lucky to be able to invite Master Xu in my Zhang family."

Xu Yidan nodded reservedly, and he said lightly: "Zhang Yuanwai, Xu has limited time and has no time to waste. I think we'll start now."

"Master Xu, please." Zhang Jianjie quickly raised his hand and made a false inducement action.

Xu Yidan stepped forward and walked to the front of everyone. There were several tables placed there, with many items on it, including stoves, mortars, crocks, casseroles and other items, which were all tools for boiling medicine and making medicine.

Xu Yidan stood behind the table and faced everyone. As soon as he opened his mouth, he went straight to the topic and said, "Everyone, what I am talking about today is the technique of pharmaceuticals. The so-called pharmaceutical arts are to boil, extract the essence from the herbs, and make them into powder, ointments, pills, etc., so as to facilitate the use of patients. The first step in pharmaceuticals is to choose medicines. If the medicine is not selected well, then no matter how exquisite your pharmaceutical arts are, the medicines prepared are also failures. Let's first talk about how to choose medicines."

Gong Yaoshi and others all listened with breath, even Li Wenjun was no exception. He listened carefully, for fear of missing Xu Yidan's words. Perhaps any sentence he missed was an opportunity that he could not find for a long time.

Xu Yidan is worthy of being a famous doctor from the capital. He has his own unique and profound understanding of all the steps of pharmaceutical technology. What he said this time may be just a small part of the knowledge he mastered, but even so, it made Kong Yaoshi and others fascinated.

Li Wenjun is a completely out of the art of doctors. Many things Xu Yidan said were somewhat obscure and difficult to understand and extremely difficult. In a very rare occasion, he could verify and deepen his understanding from Xu Yidan's explanation with what he saw in "Changchun Gong" and "Miscellaneous Treatise on Immortality" and "Miscellaneous Treatise on Immortality".

An hour passed in a blink of an eye. Xu Yidan stopped. He pointed to the many objects placed on the table and said, "That's all for today. Everyone should take a break. After half an incense stick, I will demonstrate to you how to make medicine in public. During the demonstration, I will take time to answer your questions. You can take advantage of the rest and think carefully and ask me what you want to ask me later."

Everyone was immediately excited, and Li Wenjun was also full of expectations for Xu Yidan's upcoming demonstration.

The half-incense stick passed quickly. After resting for a while, drinking tea, Xu Yidan, who had moistened his throat, walked back to the back of the table. He took out a bag and opened it, and saw that there were many paper bags inside. After the paper bag was opened, it was covered with various herbs.

"The medicine I'm going to make is the golden sore medicine. You can see how I make the medicine." Xu Yidan said as he began to weigh herbs with slags.

Xu Yidan's movements were very stable, and the steps were explained very clearly, with clear structure and no confusion at all. He weighed the herbs needed for refining the golden sore medicine as needed, then used a mortar and other treatments, poured them into a casserole, and then started to boil them.

Boiling medicine is very time-consuming, so Xu Yidan used this time to ask everyone questions at will. Of course, it is said that it is casual, but there are actually restrictions. Each person only has one chance to ask questions, and he can only ask one question. For each person, whether he can ask questions must be decided by drawing lots.

Li Wenjun really wanted to ask how he should refine the gathering of energy if Xu Yidan stood in his position. However, it was unwise to do so, so he chose to give up asking questions without hesitation.

Soon, the draw ended, and only ten out of the fifty people got the opportunity to ask questions. They quickly seized the opportunity and asked Xu Yidan about the questions in their hearts.

Xu Yidan answered patiently, Li Wenjun frowned, and nine people passed by in a row. He was depressed to find the question of the questioner, but he couldn't understand. Xu Yidan's answer was also confused when he heard his ears. Listening to the question and answer between Yaoshi Kong and Xu Yidan, he was almost the same as listening to the heavenly book.

Li Wenjun thought to himself: I lost, I lost.

Although Xu Yidan's lectures answered some of his questions, they did not help him to refine the gas accumulation and dispersion, and the alchemy furnace he most wanted to see had no shadow at all.

At this moment, the last questioner stood up. The man seemed to be a doctor. He asked, "Master Xu, I have a patient who is sick in bed for a long time and is not awake. I can't get the medicine soup in, and I can't get the pills in. What should I do to give him medicine?"

Xu Yidan said: "If you use medicine to a patient, you don't have to send the medicine to his mouth and let him swallow it. There are other ways. For example, you can boil the herbs into soup, bathe him and wipe it, or make it into ointment and apply it to him. Of course, doing so will reduce the efficacy of the medicine, and some diseases are not suitable for these two methods. I am trying a new method recently, creating a hollow iron needle, and then pierce the iron needle into the patient's blood vessels and pour the medicine liquid directly into the patient's body."

boom!

The school suddenly became a sensation and everyone was talking, as if they had heard a fantasy.

The noisy discussions between Kong Yaoshi and others were ignored by Li Wenjun. He sat there with his eyes dull and muttered something. At first glance, he seemed to be possessed.
