Li Feng was in a relatively comfortable mood when he pulled a large cart of silk with a ox cart and left Yuwen Kai's temporary station with a ox cart. He decided to deepen his cooperation with Yuwen Kai in the future.

As for copper coins, they have silk shops, so of course they use silk to pay for it. Don’t be jealous of money. At this time, silk fabrics are also hard currency, and because they are lighter, they are easier to use than copper coins and are the preferred currency.

When they returned to the clinic, they handed the silk to Master Yin. The students were not surprised. They thought that Master Li's ability to make money might be more skilled than medical skills.

He went to comfort his grandmother again. The old man was a little dazed and obviously hadn't recovered. Li Feng briefly explained his plans to his grandmother, and finally said confidently: "Grandma, it takes less than a year. The family side will have to use the eight-carrying sedan chair to invite you back. Moreover, even if we carry them, we won't go back!"

Grandma still believed in her grandson's ability, and most of the worry on her face disappeared. The little Nannan was also happy and even pulled her elder brother to ask, "What is the eight-carrying sedan chair? Eight, the grandma seems to be unable to sit alone, can Nunu be good enough?"

I forgot that there is no sedan chair at this time, but it doesn’t matter. At worst, I can make one at that time.

In the following days, in addition to guiding the students in the clinic, Li Feng guided everyone to prepare medicines, various pills, pastes, pills, etc. Of course, there is also the most important penicillin. Others are not allowed to interfere in this work, only Yasha and Rakshasa were secretly in charge.

The cooling oil that Li Feng had been thinking about finally came out. Niu Er dug a piece with his finger and stuffed it into his mouth. While savoring the taste, he nodded: "It tastes pretty good, it's a little cool breeze."

"This is used externally!" Li Feng didn't know what to say about this guy. He also drank alcohol and cool oil, and he was simply a monster.

Niu Er didn't care too much, anyway, anyway, he couldn't even vomit it out.

Li Feng was also inspired by some: he really had to get some oral cooling and anti-smoking medicine. The best one was Huoxiang Zhengqi Water. The most convenient one was Rendan.

The human pill is almost extinct in modern society. But before liberation until Li Feng was young, it was a life-saving medicine for summer.

Even now, if you go to Africa on a business trip and take out a bag of human pills to give to the locals, you will be regarded as a guest of honor immediately, which is absolutely good.

The human pill is packed in a small paper bag, which is about the size of a match head. Because it has the ingredients of cinnabar, it is red in color. A few pills are stuffed into your mouth, which are cool, cool and relieve heat. Children are happy to play with it.

In addition to the human elixir produced in our country, there is also the "Rendan" produced in the island country, which is the one with two small beards on the advertisement. Therefore, the beard is called Rendanhu.

Before liberation, the island country dumped Rendan to China, which aroused dissatisfaction among patriots. So a patriotic industrialist named Huang Chujiu organized manpower to develop Chinese humandan based on the recipe of Zhuge Zhenjunsan in ancient times.

After fiddling with it for two days, the human pill was produced, but due to the equipment, the output was not improved. It was too difficult to make pills. Just keep the most affordable form of medicine and pour it into the patient's mouth.

In this way, the name cannot be called "Pan", but it cannot be called "Ren San". Just restore the original name and call it "Ming Jun San".

However, during the experiment, I still knitted dozens of human pills. It happened to be discovered by Nunu and Miss Wuyou, who was invited by Nunu, to be a guest.

The two little girls and their family stuffed a pill into their mouths, and then wrapped all the elixirs of their elder brother and husband, probably to be eaten as snacks.

Li Feng was about to tease them when he saw Niu Er rushing in in a panic with a man on his back, followed by a large group of students.

When Li Feng saw that the person Niu Er was carrying was Xue Daoheng and Master Xue, he was also anxious and asked Niu Er to put the person on the chair. While taking the pulse, he observed Master Xue's expression.

The old man's face was dusty, obviously thinner than when he first arrived in Luoyang, his face turned pale and cold sweats were rising on his forehead.

After checking the pulse, Li Feng breathed a sigh of relief: "It's not a big deal, it's just a tiring journey, and the weather is a little hot. Master, you are so old, don't be able to bump around again in the future!"

Is there any disciple who teaches his master like this? You are promising, right? Xue Daoheng was about to stare at him, but then he thought that the disciple was also thinking about him, so he smiled bitterly and shook his head: "You are the doctor, you have the final say, you have the emperor's grace, and you dare not refuse!"

The students next to them also breathed a sigh of relief. Just now, I thought the old man was not going to be able to do it. But why didn’t Master Li give me medicine?

Just as he was puzzled, Li Feng waved to Nunu, the little guy came to Xue Daoheng, took out a few human pills, and stuffed them into Xue Daoheng's mouth: "Grandpa ate Candies."

Tangdoudou, do you think I am a child? Xue Daoheng was a little amused. But soon, a coolness surged in his mouth, which rushed upwards, penetrated his lungs, and became much more transparent in his body.

He tried to exhale a breath of turbid air and reached out to touch Nunu's little head: "This sugar bean is really effective, and grandpa will be fine immediately after eating it."

Nunu raised his little head happily, then looked at Li Feng: "It was given to me by my eldest brother, the eldest brother is the most amazing-"

After saying that, he ran over, and Li Feng had to bend down and ask the little guy to kiss him in the face. Before he could stand straight, he felt that the other side of his face was also cold, and he was kissed by Changsun's little lady.

The students around couldn't help but want to laugh. Sun Erniang liked to tease her children: "Young lady likes your husband so much, why not marry me earlier, you can be with Master Li every day."

The little man said seriously: "My mother said that she has to wait until she is thirteen to get married."

Well, she was thirteen years old, it seemed that she married Li Xiaoer that year.

Li Feng waved his hand and drove away all the students who made fun of him: "It's useless to teach you how to refine the marching sanctuary, right? Why don't you know how to take Master Xue?"

Everyone dared not say: If it weren't for Mr. Li, you, we would have given it to you long ago.

So he scattered, and Nunu divided the remaining human pills to Xue Daoheng half of the old ones. The old ones, I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and I was one by one, and

Seeing that Changsun’s little lady was also happy: “Husband, this kind of sugar bean is more effective than the golden elixir of Taishang Laojun. Husband, did you steal it from Laojun’s alchemy furnace?”

Alchemy furnace, stole it - is this to treat me as a grandson again, right?

Li Feng looked at Changsun's little lady depressedly, but saw her covering her mouth and laughing secretly. It was obvious that she was deliberately joking about him just now. This little girl knew she was teasing people, right? But the little look at that moment actually made Li Feng's heart tremble.

He shook his head twice and threw away his distracting thoughts. Then, he saw Xie Yingdeng trot into the house: "Brother Feng, the charcoal has been refined, the Taoist priests are waiting for you to go back and refine glass!"
