Zhao Lei looked at Tian Yan with a shocked face, he never expected that Tian Yan had a wide range of contacts and was sought after by dignitaries and nobles, because he had the technique of pox to prevent smallpox.

Smallpox is a virulent infectious disease caused by a filtering virus, with a very high mortality rate, usually up to 25 percent, and sometimes even as high as 40 percent.

There is a saying in the Northern Song Dynasty: "Only half of the children are born, and smallpox is complete." It can be seen that smallpox was in danger in the Northern Song Dynasty.

As far as Zhao Lei knows, as early as more than 3,000 years ago, people had seen smallpox scars on Egyptian mummies, and India also had this disease in the sixth century BC.

In the Middle Ages, smallpox was widely prevalent in all countries in the world, almost 10% of the inhabitants died of smallpox, one of the five people had pockmarks on their faces, and even the emperor was not spared, the French Emperor Louis XV, Queen Mary II of England, the German Emperor Joseph I, the Russian Emperor Peter II, etc., were infected with smallpox and died, and during the Northern Song Dynasty, most of the royal heirs and children of dignitaries died of smallpox.

In the eighteenth century, more than 150 million Europeans died of smallpox, smallpox was brought in by the Spaniards in the sixteenth century, it is reported that smallpox was epidemic in the United States in 1872, more than 2,000 people died in Philadelphia alone, and in Russia, from 19oo to 19o9, 500,000 people died of smallpox, which shows that smallpox is an extremely dangerous infectious disease.

In the Central Plains, as early as the two Jin Dynasty periods, there were records about smallpox, and Ge Hong's "Preparation for Emergency Prescription Behind the Elbow" of the Jin Dynasty described the symptoms and epidemic situation of smallpox for the first time: "When there is a disease than the year, it is the sores on the head, face and body, and the turn around the body must be around for a while, like fire sores, all of which contain white pulp, and they will be born with the decision, and if they are not cured, the dramatists will die." Those who are poorly cured, the sores are purple and black, and they will be extinguished at the end of their lives, and this vicious breath will be extinguished. According to Ge Hong's "Elbow Preparation", it is recorded: "The result of the capture in Nanyang in Jianwu is called a captive sore." It is believed that this disease was introduced to our country in the first century AD, and it was brought by captives during the war, so it was called "sore".

Since then, there have been records of smallpox in the classics of our country, although the names of the diseases in each book are different, but from the symptoms described, there is no doubt that it is smallpox. Since the Tang and Song dynasties, the disease has gradually increased, the transportation is reachable, the personnel exchanges are frequent, smallpox is widely prevalent in the Central Plains, and even spreads to the deep palace forbidden, becoming a violent danger in the entire Northern Song Dynasty.

Zhao Lei was born in a family of traditional Chinese medicine, the disease of smallpox, very familiar, but after a thousand years has been completely eliminated, only in the books have been seen, as far as he knows, the Qing Dynasty Zhu Chunyi's "pox rash conclusion" once recorded a story, said that the prime minister Wang Dan during the Zhenzong period, several children died of smallpox, after Wang Su was born, Wang Dan was afraid of accidents, and found a miracle doctor Taoist priest in Mount Emei to give Wang Su pox, as a result, Wang Su was not infected with smallpox, and lived to be seventy-six years old.

But Zhao Lei always thought that this was a false story, but when he heard Tian Yan's words, he thought about the time, place and characters in the story, and immediately thought that the person who gave Wang Su pox was very likely to be a Taoist priest of Peng Zu's lineage.

"Master! The Emei Divine Doctor Taoist who gave Wang Su pox back then wouldn't be a person from our Peng Zu lineage! Zhao Lei asked in surprise.

Tian Yan smiled proudly and said: "I didn't expect this incident from decades ago, but there are still people who know about it, not bad!" That's exactly what your ancestors did back then! ”

No way! Zhao Lei was stunned, he didn't expect to meet a pox master who appeared more than 500 years later in the Northern Song Dynasty.

"Master! What the hell is the pox all about! Zhao Lei asked curiously, smallpox has been extinct after a thousand years, many doctors don't know about this disease, let alone treatment, Zhao Lei only heard that the pox is taken from cowpox, and other things are not clear.

"Pox in the Central Plains, has a history of hundreds of years, as early as Ge Hong's "Elbow Preparation", began to study the prevention and treatment of acne, and later used poison to prevent smallpox, so began to start the medical research of pox.

In the past, the earliest means of prevention was to make buffalo lice and powder into cakes or burnt ashes and porridge and rice, but there was no effect at all, and then it was developed into the pox clothing method, and the sore-affected underwear was put on by the inoculated person to cause infection, but this method had a high mortality rate, and then gradually ceased to be used, and then the research came out, which was the pox pulp method, that is, to take the pulp of the pox, and use cotton to plug the nostrils of the inoculated, but this method had a higher mortality rate and was also abandoned.

Now we are using the dry seedling method and the water seedling method.

The dry seedling method is to dry and grind the pox scab and blow it into the nostrils with a silver tube; The water seedling method is to grind the acne scab finely and mix it with water, and stuff it into the nostrils with cotton staining.

These two methods have their advantages, the dry seedling method pox is violently toxic, but the effect is wonderful, only suitable for people with strong bodies; The water seedling method is not very toxic because it is diluted with water, and it is used for people with weak bodies.

But the two methods also have their own shortcomings, the dry seedling method is too toxic and easy to kill, and the water seedling method is too peaceful and not easy to infect, so what seedlings to use, how to use seedlings, and the treatment after seedlings are the most important things, which is also the main reason why pox can not be promoted. Tian Yan said with a sigh.

"Why not use cowpox! Cowpox is not fatal, and it is very infectious, so it can prevent acne after planting! Zhao Lei asked disappointedly when he heard that there was no cowpox method in later generations.

"Cowpox! Haven't heard of cowpox can also be planted in people! Cows are beasts! Tian Yan looked at Zhao Lei strangely and asked.

"Absolutely! Master, you should go to the field and ask, there are many cattle farmers who are infected with cowpox, which is rarely life-threatening, but it can prevent acne, and cowpox is more effective than any dry seedlings and water seedlings, and there is no danger to life! Zhao Lei said loudly and affirmatively.

"Really! Master immediately sent someone to investigate, if cowpox can really prevent acne and is not life-threatening, you will definitely leave a heavy mark in history, this is a great act of kindness that can save thousands of people! Hearing Zhao Lei's affirmative words, Tian Yan absolutely believed in Zhao Lei, just as he believed that he could save the patient just now.

"Cowpox will definitely prevent acne!" Zhao Lei continued to affirm.

"In that case! Master will send someone to investigate now! Tian Yan finished speaking with some excitement and walked quickly outside.

………………………………

Tian Yan was reminded by Zhao Lei, and in the next few days, he took Xiaodao Tong everywhere to investigate the feasibility of collecting evidence and planting cowpox, while Zhao Lei, staying in the Taoist temple, began to read Tian Yan's "Elbow Preparation", "Qianjin Fang", "Outer Taiwan Secrets", "New Materia Medica" and other ancient books of medicine.

Zhao Lei's life is relaxed and fulfilling, reading in the morning and evening, helping Tian Lan take care of patients in the Taoist temple during the day, and flirting casually.

And the patient who Zhao Lei was treated by blood transfusion successfully got out of the danger period and slowly recovered, and he was even more grateful to Zhao Lei who saved him.

Zhao Lei's use of blood transfusion to revive the dying patient spread throughout Wuyang in just a few days, and there is a tendency to gradually expand outward, this qiē is thanks to Tian Yan, he accepted Zhao Lei as a disciple, greatly improving Zhao Lei's status in the medical field, otherwise only one patient was cured, how could he become famous so quickly!

But Zhao Lei's Western medicines and medical devices are useless again, after all, no one will believe in strange drugs that they have never seen or heard of, and no one wants to be cut into pieces by Zhao Lei.

The weather is getting hotter and hotter, and it has reached the scorching heat of July, and in the era when there is no air conditioning and ice cream, Zhao Lei feels that summer is particularly difficult.

In the early morning, it was drizzling again, the weather was very cool, Zhao Lei was dressed in a short shirt, and read hand medicine under the pavilion outside the Taoist temple.

At this moment, at the official road position on the west side of the Taoist temple, there was a sound of horses' hooves.

Not a carriage, it's a cavalry! Zhao Lei immediately judged from the sound of the horse's hooves that it was a person galloping on a horse, this was not that he was smart, but a lone horse, in the drizzle, had already met his eyes.

This is a military horse, galloping by a lone horse, and Zhao Lei clearly saw the imprint of the military horse on the horse's hips.

What are the military horses doing in the Taoist temple? Watching the lone horse gallop into the Taoist temple, Zhao Lei got up and thought strangely.

Just when Zhao Lei was puzzled, the rarely used carriage of the Taoist temple was actually pulled out, and Tian Yan also carried the medicine box, rushed out of the Taoist temple, ran to the pavilion, and said anxiously to Zhao Lei: "Quick! Prepare, Meishan County Ling Ge has a carbuncle and his life is in danger! ”

Carbuncles! Two months of bad supplementation made Zhao Lei understand that the so-called intestinal carbuncle is appendicitis after a thousand years.

Is appendicitis in such a hurry! Zhao Lei thought strangely.

During the Northern Song Dynasty, acupuncture, massage, traditional Chinese medicine and other medical fields have reached a peak, and the small disease of intestinal carbuncles, a few injections, two pairs of traditional Chinese medicine, and a few more massages, there is no problem at all, so there is no need to think about the future generations, and the surgery is so strict at every turn.

"Master Ge used to have a sudden intestinal carbuncle, but after being cured, it turned into a chronic intestinal carbuncle, which was no big problem, but now it is sudden again, and acupuncture, massage and Chinese medicine do not work, so let us go for treatment!" Tian Yan said eagerly.

It's over, it won't work if you don't operate this time, Meishan County order, it is obvious that the appendicitis is perforated, if you don't have surgery, it will definitely be life-threatening, Zhao Lei thought uneasily after listening to Tian Yan's words.

Meishan County Ling's carbuncle is a very strict challenge to Zhao Lei, the appendix is a slender blind tube on the inside of the human cecum, but everyone's appendix length and position are inconsistent, with Zhao Lei's experience and technology, it is difficult to accurately find the correct position of the appendix in the patient's body, if the operation is successful, it is good to say, Zhao Lei will definitely become famous in one fell swoop, but if the operation fails, I am afraid that no one will dare to find him to go under the knife.

Opportunities and risks coexist! Zhao Lei pondered for a moment, and finally decided to give it a go, ran back to the Taoist temple in the rain, and took out a complete set of surgical tools from the warehouse, although there is a lack of anesthetics, but Tian Yan has a kind of zombie grass here, after eating, it can make people like zombies, although the brain is awake, but the body has no sense, and it is harmless to the human body, but the effect of the medicine is only three hours.

Ready to get ready, Tian Yan and Zhao Lei got into the carriage and began to march towards Meishan.

What awaits Zhao Lei is the first open surgery, and success will shock the world, and failure will be doomed.
