The matter of teaching children to learn words and arithmetic has been handed over to Huo Xingxing of the Huo family by Dr. He. Huo Xingxing is the little baby who couldn't persist in studying medicine for three days. Although he is really not talented in studying medicine, this baby is very talented in the subset of history, arithmetic and the like, and is far smarter than his peers.

After studying in Dr. He's private school for so many years, it stands to reason that he could go to the town to register and take the national unified imperial examination—this is one of the few opportunities for ordinary people who have not cultivated spiritual power to improve their class and become a high-ranking official. But Huo Xingxing refused.

He is kind-hearted and straight-minded, and he can't see some filthy things done by officialdom, if he enters the officialdom, he will be swallowed up to his bones in minutes.

After thinking about it, it is better to learn from Dr. He to be a private school teacher and benefit the village children. It just so happened that Dr. He wanted to concentrate more on teaching Yang Yongyong, so he simply handed over the work of the private school to Huo Xingxing.

Under the guidance of Dr. He, the young man was energetic, and he contracted an idle dilapidated house in the village, decorated it, arranged the tables, chairs, benches, blackboard chalk, and began the enrollment teaching.

In the past few months, the small private school has been run impressively and has been unanimously recognized by the villagers. As his mentor, Dr. Ho is very pleased.

The children of Yangshu Village are all his students, but Yang Yongyong is a special one, because he is the personal disciple who has held the apprenticeship ceremony.

In the blink of an eye, it was time to teach alchemy skills as agreed. On this day, Dr. Ho led Yang Yongyong to the storeroom that is usually used to stack herbs.

As usual, there are piles of dried herbs, as well as some mineral and animal medicinal herbs.

But unlike usual, there is an extra table in the middle of today's storeroom, and there is a swarthy three-legged tripod on the table.

"Apprentice, this is the alchemy furnace used for the teacher's alchemy, called Qiming Ding." Physician He stroked the three-legged Xiaoding, and his expression couldn't help revealing a trace of nostalgia, "This was given to me by your master on the day I left the school, and he hoped that I could take this Danding with me to walk the mainland and benefit all the people." ”

"It's a pity, I finally failed my master's expectations." Doctor He sighed, his eyes stained with a little sadness, "Practicing medicine and healing in Yangshu Village over the years can be regarded as more or less making up for my mistakes." ”

"Master......" Yang bravely whispered worriedly.

"Forget it, let's not talk about it." The corners of Dr. He's mouth twitched, he waved his hand expressionlessly, took a few deep breaths, and straightened his waist again.

"Apprentice, let's start talking about this alchemy now." Doctor He sat in the rocking chair, smiled, and said.

"Hmm!" Yang Yong sat on the small bench with a serious expression, ready to listen to the lecture.

The history of alchemy had already been told to Yang Yongyong in the past teaching. Today, I want to talk about the classification of alchemists on the Xuanwu Continent and the medicinal materials used in alchemy.

On the Xuanwu continent, the two schools of medicine have their own hierarchies and affiliations.

The general association of doctors in the Xuanwu Continent is located in Ancheng, the capital of the Qin State, and the other eight countries are all large branches of the Physician Association, and the names of doctors in the Xuanwu Continent are all registered. Every three years, a comprehensive assessment is conducted according to the treatment of the registered physician during the three years and the on-site inspection, and the specific cure rate is divided into four grades from high to low.

Among them, a cure rate of 90 percent or more is called a worker, a cure rate of less than 70 percent but more than 70 percent is called a middle worker, a cure rate of less than 60 percent but more than 60 percent is called a layoff, and a cure rate of less than 60 percent is called an inferior worker, but if the cure rate is less than 40 percent, they will be directly deprived of medical qualifications, so as not to delay the disease and harm people's lives. Doctors who can be supported by the royal family and the family are almost always working.

The Veterinary Association is affiliated to the Physician Branch, which mainly treats veterinarians of common animals, such as poultry, pigs, cattle and sheep, and is called a domestic veterinarian; And the veterinarian who can treat spirit animals is called a spirit veterinarian. There is no clear hierarchy among veterinarians, only according to the different people they treat. Because of the demand for spirit masters, spirit veterinarians are also a popular profession on the Xuanwu Continent.

Spirit beasts are different from poultry, pigs, cattle and sheep, they are born with the spiritual power of heaven and earth, have a long lifespan, and can become the fighting partners of spirit masters through contracts, or they can go crazy and carry out fierce attacks on human cities, which is sometimes a blessing and sometimes a curse for human beings.

Speaking of the Alchemist Association, it is much larger than the Physicians' Association. Its branches are also set up in the national capitals of various countries, among which the Mexican Alchemist Association is the general meeting of the Xuanwu Continent Alchemist Association. The Alchemist Association is supported by the royal family, and the Danxiang Yingmen is the place of yearning for the apprentices who have just set foot in the medical gate in the Xuanwu Continent.

According to the different levels of Dancheng, the ranks of alchemists are divided into the following categories from high to low: Supreme Danshi, True Danshi, Supreme Danshi, Shengdanshi, Xiandanshi, and Fandanshi. As the name suggests, Fan Danshi is the alchemist who refines the mortal elixir, and the Supreme Danshi is the alchemist who refines the supreme elixir.

Nowadays, the highest level of alchemists in the Xuanwu Continent is only the true Dan Master, since the battle three thousand years ago, many spirit masters and alchemist schools in the Xuanwu Continent have broken off the inheritance, and the descendants of later generations have tried their best to restore the original inheritance, but after all, it cannot be completely restored, in the past three thousand years, no one has been able to reach the realm of the Supreme Danshi, which makes the existence of the Supreme Danshi a legend, and some people even suspect that this is a realm that is impossible to reach at all.

But in fact, in ancient times, there were still Supreme Dan Masters in the Xuanwu Continent, although the number was extremely small, but there were still some of them. These records are recorded in the historical books of the medical sect passed down by Physician He, and now they are passed down to Yang Yongyong through the mouth of Physician He.

On the Xuanwu Continent, the Alchemist Association and the Physician Association are just a governing body, and the alchemists and physicians have their own sects.

Although these sects are located in the territory of the Nine Great Kingdoms, they do not accept the jurisdiction of the royal family of the Nine Kingdoms, and they can be said to be independent in their own sects.

However, after all, it is located in the territory of the Nine Great Countries, so the relationship between each alchemy sect and the royal family of the country where it is located is relatively close, and the descendants of the royal family with a little talent can directly enter the alchemy sect to study without going through the basic assessment path, which is an unwritten agreement between the royal family and the alchemists of various countries.

The alchemy sect is headed by the Xuantian Sect in the territory of the Mexican Kingdom, and its sect master is Master Mo Mingsha, the current president of the Mexican Alchemist Association, and he is also one of the few true Dan masters in the Xuanwu Continent.

The Physician Sect is not as powerful as the Alchemy Sect, and the most large-scale is the Zhongsheng Sect founded by Zhang Zhong, the medical saint of the Xuanwu Continent, which is located in the territory of the Zhou State. Most sects are only the size of a small mountain village, and the number of disciples is generally no more than 50 people, and the disciples are scattered in different places in the Xuanwu Continent, following the teacher's instructions to cure diseases and save people.

After registering with their respective associations, alchemists and physicians are given an exclusive metal coat of arms according to their respective ranks, which can be worn on their bodies as a symbol of their status. The issuance of each coat of arms is registered, and each coat of arms has its own number, one number corresponds to an alchemist or physician, which is not allowed to be impersonated, nor is it allowed to forge the coat of arms without permission.

If there is no such coat of arms, it is an unlicensed practice of medicine, and the patient can appeal to the Alchemist Association or the Physicians' Association according to this situation, and the practitioner can be punished.

Doctor He was wearing a coat of arms representing work, which made Yang Yongyong wonder: according to the 100% cure rate of his master in Yangshu Village, how could it be the coat of arms of work, right? Why is that? Moreover, the master said that he was an alchemist, but why did he never see the master take out the alchemist crest? Don't you just want to take it out? Or is there something else going on?

Forget it, since the master didn't explain, it means that the master doesn't want to mention this matter, so let's not ask for now. Well, first follow the master to learn the alchemy skills well!
