Liu Jin went back to Beijing more often than Chen He, and heard about Yu Xi's rumors, so he couldn't help but "gossip" with Chen He.

Of course, he couldn't imagine that Yu Xi was an existence from another time and space, not to mention that with the narrow cognitive ability of the ancients about this world, even a high-achieving student like Yu Xi in the 21st century would be inexplicable.

People are accustomed to blaming ghosts and gods for unexplained things, such as these old people who saw that Yu Xi had advanced thinking ability, medical skills, and some abilities that they did not have, so they naturally felt that she was not a mortal.

Chen He listened to Liu Jin's words, and then looked at Yu Xi, how did he think that the rumors were true.

Big peach blossom eyes, pointed chin, and a pitiful little melon seed face, what is this look like a fox?

Moreover, when Yu Xi looks at people, how can he be comparable to the cleverness of mortals?

Chen He stared at Yu Xi and couldn't help but be stupid.

Yu Xi was busy experimenting with her "hand **", and she had no time to take care of these two people.

With the small space and combustibles in place, the next step is to prepare the combustion conditions.

In the 21st century, the hand ** can explode with a pull and a throw, but she can only put open fire into it. This open flame can neither be too fast nor too slow, and it is by no means an easy task.

Why not put black ** in the sheep's bladder? Yu Xi didn't think about it, but when the black ** burned and exploded, the controllability was relatively low, and it was too dangerous for the soldiers of Feng Kingdom to ignite it with bare hands.

Eventually, she used a hollow bamboo tube to insert it into the small opening left by the sheep's bladder, and left a noodle thread in the bamboo tube that looked like an oil wick, but this wire was more flammable, burning faster than the wick of an oil lamp, and would become shorter in a suitable time.

A person buried himself in the experiment for most of the day, and when the sheep's bladder exploded, Yu Xi's face was as dirty as a little cat.

This experiment was considered a success, and Yu Xi immediately told Gong Chengyun about the progress. Gong Chengyun was overjoyed, and hurriedly asked Chen He and Liu Jin to go to the baggage camp to support the silver, and followed Yu Xi to purchase a large amount of finely ground flour and sheep bladders.

The flour is okay, originally the soldiers of Fengguo ate steamed buns, and they were not fine enough to grind a few more times, and a few more sieves would meet the requirements.

But sheep bladder is not so simple.

Ningcheng in Fengguo is only separated by a mountain from the shepherd's city, but the economic environment and customs are completely different. Fengguo pays attention to farming, raising silkworms and spinning yarn, while most of the herding cities in Tanran make a living from grazing.

Most of the beef and mutton eaten by the people of Fengguo are purchased from the people of Tanran on the border line, and the refined grain eaten by the people of Tanran is also imported from Fengguo.

As a result, over the years, the two countries have been at war on the one hand, and on the other hand, they have to have certain economic exchanges.

The army needs a large number of sheep bladders, and Yu Xi knew that it was difficult to buy affordable and large sheep bladders in Fengguo, so he had to mix with Chen and Liu Jin to buy them.

Yu Xi and his entourage came to the largest slaughterhouse in Tanran Mucheng and found the boss to discuss the procurement problem.

The boss was a middle-aged man with large white spots on his face and neck, like a cow with black and white flowers.

Yu Xi knew that he had vitiligo at a glance, and said that he could teach him some treatment recipes after buying things.

Who knew that he saw that Yu Xi and others were Fengguo accents, and the demand was large, and only he could supply the goods in the entire Mucheng, so he felt that the strange goods could be lived, and the price of sitting on the ground was raised, and the original one or two silver could buy several large baskets of sheep bladders, and he would ask for one or two silver when he opened his mouth.

The army is in high demand, and the three of them calculate that they need at least more than a thousand, that is, more than a thousand taels of silver. More than 1,000 taels of silver to buy sheep into the water, but are you crazy?

Yu Xi's heart was broken, but his face was silent.

The first time there was no negotiation, and after coming out, several people discussed countermeasures.

"Two ways: either go to another small slaughterhouse to make up, or kidnap his wife and kidnap him." Chen He was indignant and proposed.

Liu Jin shook his head: "Absolutely not." The war is urgent, and the small slaughterhouses are getting together, and it is too late. If he kidns up his wife and children and threatens him, it is even more undesirable, even if he is a citizen of another country, after all, he is adjacent to our country, and he will lose the hearts of the people, and the world will not last long. ”

Feng Guo and Tanran have had a grudge for a long time, and several cities were snatched from Tanran. Liu Jin said this for the sake of defending the people.

"So what do you say?" Chen He had no choice but to ask.

Liu Jin couldn't think of a solution.

Yu Xi frowned, thought for a moment, and said, "I have an idea, I can talk about the medicine and exchange it with him." ”

"Medication exchange? What medicine costs a thousand taels of silver? The two were puzzled and asked in unison.

"I can cure him of his madness." Yu Xi said, "There is no other good way now, you might as well give it a try." ”

Yu Xi remembered that there was a record in the "General Record of Shengji" of the ancients: "On the form of vitiligo, the liver is hot, and the wind evil takes advantage of it." Wind and heat are combined, spreading the camp guards, stagnation muscles, and not dissipating for a long time, so it has become this. "Something to the effect that the cause of vitiligo is due to the fire on the liver and the wind cold entering the body, and the wind is strong by the fire, resulting in the formation of the wind cold that does not heal for a long time.

"Introduction to Medicine" wrote, "Red vitiligo is caused by liver wind beating on the skin, and blood and qi are not in harmony." "Materia Medica" also says that "vitiligo" is caused by blood deficiency in the liver and wind, "covering the liver is the position of wind and wood, hiding the blood organs, blood deficiency is fever, and heat is even wind." "Medical Forest Correction Error" clearly states that "vitiligo, blood stasis in the skin".

It can be seen that skin hypopigmentation diseases involve the lungs, liver, and heart, and are related to external wind, internal heat, external dampness, qi, and blood, and the pathogenesis is qi and blood disharmony or qi and blood stasis, and the disease is located in the skin and muscles. In the 21st century, the treatment of vitiligo often adopts methods such as dispelling wind with blood, soothing the liver and relieving depression, promoting blood circulation and removing stasis, and clearing dampness and heat. It is also in the same vein as the ancients.

The methods of treating vitiligo in ancient times were mainly divided into internal treatment, external treatment and moxibustion.

The internal treatment method has four fundamentals: dispelling wind and dispersing evil, dispelling wind and channeling, promoting qi and invigorating blood, and strengthening righteousness and dispelling evil.

Yu Xi remembered that the "Introduction to Medicine" discussed in detail the syndrome differentiation and treatment of "vitiligo" and the points to be paid attention to: "Bai belongs to qi, those who are hot, those who are poisonous, sepsis powder or Xiao Chai Hu Tong plus fengfeng, forsythia, those who are deficient, tonic and beneficial qi Tongjia qianghuo, and fengfeng, if it is a person who is poisonous, Hu Ma San, a single Cang'er pill, and a single duckweed pill, if this disease lasts for a long time, it is only suitable to nourish qi and blood, then the fire is self-resting, the wind is self-determined, and the itching is self-stopping. ”

But this book does not exist in this era, it was imprinted in her mind when she was studying Chinese medicine in the 21st century.

The external treatment method mostly uses wind-dispelling drugs: duckweed, self-defense, mulberry ash, capsule, Xanthus leaves, snake molt and other drugs are often used. For example, in "Taiping Shenghui Fang", it is washed with capsules and wood to prevent burnt ashes and juice.
