Tian Liang, Huang Bochun, Zhao Zhongjing, Ananda, and Ji Ji sat around the fire, taking turns sipping the liquor in the bowl while eating. The five of them were all young people sent by Miao Jiang to study in the Perak Army, and they had been friends before they came. They had been under Perak for almost a month and had not seen each other. On the one hand, this is because after getting off the boat in Chongqing Mansion City, they were led to their respective study places. On the other hand, it is also because of the heavy academic schedule, and the schedule is extremely tight, and I have to attend classes even at night. Because of the Spring Festival, each teaching site has a three-day holiday. "Thinking of relatives every festive season", several people thought that tomorrow would be the Spring Festival, so they made an appointment to have dinner at a restaurant in Chongqing Fu City on the 30th night of the Chinese New Year's Eve.

This year's winter was exceptionally cold, with a snowfall the other day. In the middle of winter, it is also a great pleasure to eat oily meat and fragrant wheat cakes around the fire. What is especially happy is that Tian Liang took out a bottle of wine from his arms like a trick, which made everyone smile. The Perak Army's ban on alcohol was to prevent the consumption of precious food, mainly to combat the brewing and sale of commercial liquor. In fact, the Perak Army officially runs a distillery, and in addition to purifying medical alcohol, the wine produced is also available to the public on festivals, but in very small quantities. Tian Liang's bottle of wine was brought by him from Banshu.

Those who can come to the Perak Army to study are naturally young talents, and these five people are no exception. Tian Liang, Huang Bochun, and Zhao Zhongjing are the children of the big family in Banzhou, and Tian Liang is the son of the head of Tian University. The three of them studied in the direction of military, teacher, and doctor, which is also the most important thing in Banshu. Ananda and Jiji are from the Hao chieftains of Zhenzhou and Luo's ghost kingdom respectively, and their study direction is industry, mining and agriculture. These two places are extremely backward in production, and the soldiers are extremely brave and good at fighting for limited resources. Therefore, they did not disdain to learn how to fight with the Thunderbolt army, but were more interested in how to mine and smelt iron to build weapons and farm tools, and how to increase grain production to fill the crop.

After drinking, several people opened up their chatterboxes and talked about their studies in the Perak Army. The first speaker was Ananda, who studied in Wanjiaping. After large-scale mining, the resources in the Jiguan Mountain have been depleted, so that the mine is getting deeper and deeper, and the mining is becoming more and more difficult. The mining centers of the Perak Army are now in Linqiong, Huojing, and Dayi in Qiongzhou, and in order to improve efficiency, new factories are also set up near mines. At present, although there are still many coal, iron and other mines in Liuliba and Wanjiaping, and some production workshops, the technology and production capacity are far less than the new mines and new factories in Qiongzhou and other places.

In addition to secrecy, the more important reason for arranging the personnel of Miaojiang to study industrial and mining in Wanjiaping instead of Qiongzhou, which is more selective, is to adapt to the local productivity level, achieve rapid learning, and quickly take root in Miaojiang. Compared with the Banzhou industry and mining industry, the surrounding tribes are even poorer and whiter. Although the selected people can understand Chinese and even recognize some Chinese characters, they have struggled to study in Wanjiaping. The technology of the new mine and factory in Qiongzhou has been iterated many times, and it is not only difficult to learn, but also a long-term process.

Ananda's learning experience is a case in point. There are a total of 100 people who studied industrial and mining technology in Wanjiaping, including 60 people from Banzhou and various tribes, and 40 people from Yibo area. These trainees will first mine for three months, smelt for three months, and finally learn to cast. The training of students is mainly practice-oriented, supplemented by theory. If you want to say that practice is good, after all, it only takes strength to pick up a sledgehammer and work hard, and it is difficult for Ananda. But Ananda didn't understand the theory at all, and often dozed off as soon as he took the theory class, and the instructors who taught it were helpless, after all, it was not only Ananda who dozed off, but a considerable number of people.

"When I arrived at Wanjiaping, I realized how powerful the Thunderbolt Army was," Ananda sighed with a sip of wine. When these 100 students first arrived in Wanjiaping, they did not start learning first, but visited the industrial and mining production first, so that they could have a preliminary concept of the production process and links, so as to facilitate teaching. The trainees first visited the bottomless mine and the mountains of coal, iron ore and other ores outside the mine. Next, we visited the coal and coke plant, smelting blast furnace and material warehouse. What shocked Ananda the most was the foundry. In his words, the Wanjiaping foundry produced farm tools, swords and other weapons in one day, which was equivalent to the annual production of his tribe, and the quality of iron tools was even better. And I heard from the teacher that the production capacity of Wanjiaping Foundry can only rank in the middle and lower positions among the foundries under the rule of the Perak Army.

The next person to sigh was Zhao Zhongjing, whose barefoot Langzhong training school was in Hengyuan Village. The transportation and location of Hengyuan Village are extremely superior, so with the recovery of the economy, the Thunderbolt Army rebuilt the village on the original site. Unlike the original wooden wall, the current wall is made of concrete walls filled with rammed earth, and there are moats outside. Coupled with the protection of the adjacent Yokohara Fort, the safety is naturally safe, and the people in the village can also evacuate to the Cockscomb Mountain in the midst of the war. The Perak Army's barefoot doctor training school was located in Hengyuan Village, and in addition to 60 students from Miao Xinjiang and 40 students from Yibo, the school also had 300 local students.

When he first heard the name of the school, Zhao Zhongjing was quite puzzled. Later, after hearing the explanation of the school teacher, I understood why it was named Barefoot Lang Middle School. It turned out that according to Ouyang Xuan's idea of running a school, not only could the people see the disease, but also could afford to see the disease. According to the traditional system of mentoring and apprenticeship, it takes a long time to train Langzhong, but illness does not wait for people. Therefore, Ouyang Xuan adopted the idea of industrial production, quickly formed a group of Langzhong, and first solved the problem of whether there was or not. The reason why it is called barefoot is because after these students became Langzhong, they did not detach themselves from production, but took root in various reclamation points and industrial and mining enterprises, and engaged in industrial and agricultural production while treating the diseases of the people.

Different from the traditional master-apprentice teaching, the school's theoretical courses, especially the courses on the five elements of traditional Chinese medicine, are not much, but more practical skills training such as diagnosis and treatment of common diseases, public epidemic prevention knowledge, and the procurement of medicinal materials and the production of prescriptions. There are also many people in Zhao Zhongjing's family who are Lang Zhong, and they have been exposed to it all year round, so that he thinks he knows something about medicine. For example, according to the Five Elements, the disease is caused by the imbalance of gold, wood, water, fire, and earth in the body, although the school teachers did not deny the claim, they believed that some of them were caused by microorganisms.

For this reason, Zhao Zhongjing also argued with the instructor, but the instructor did a comparative test to convince him. The core of this experiment is the newly developed microscope of Thunderbolt Junma, under which Zhao Zhongjing really saw the wriggling protozoa, schistosomiasis and other disease-causing pathogens. It is said that this microscope is much more difficult to make than a telescope, and the lens grinding is very difficult, and it can only achieve a low magnification of dozens of times at present, and it is not yet possible to grind a high-magnification lens.

Of course, the school and the teachers did not deny the Five Elements Theory, but pursued the standard of pragmatism in teaching in line with the principle of "no matter whether it is a black cat or a white cat, catching a mouse is a good cat". Ouyang Xuan expressed his support for this, believing that "practice is the only criterion for testing truth." Under the guidance of this kind of thinking, the school resisted all kinds of pressures, and even opened a human anatomy class, allowing students to observe internal organs and muscles, blood vessels, nerves and other tissues. In the eyes of Confucianism, this practice was not only bloody but also contrary to human ethics, and it was Ouyang Xuan who used his prestige to suppress the opposing voices. Fortunately, it was a war, and there was no shortage of corpses of the enemy, otherwise he would not have been able to convince an old pedant like Rudezhi.
