During this time, the personnel of the research institute were also busy enough with Ouyang Xuan, going to the industrial and mining production sites during the day and going to the training school at night. This is what Ouyang Xuan specially requested, because although the researchers are selected from various industries and cottages, they are both literate and flexible, but they lack practical knowledge of industry and mining, and they need to start from students. At present, the training school only holds classes in the evenings, much like the amateur night schools of later generations. There are courses in forcination, chemistry, refining, mining, commerce and trade, construction, etc., and the students are all from the management and technical personnel of industrial, mining, construction, and trading companies. Unlike other students who only study their own specialty, the staff of the graduate school also take all courses except business and trade.

Ouyang Xuan is busier than a researcher, because he also has to teach — in addition to his specialization, he also teaches politics. In terms of curriculum, Ouyang Xuan asked the school to take political courses as compulsory content in addition to professional courses, which were taught by him and Lu Dezhi. Ouyang Xuan's political ideology is mainly the idea of serving the country with loyalty, diligence and love for the people, and also tells the story of Yue Fei and Yu Jue who were loyal to the country but were framed by traitors. The content of Rude's lecture focused on instilling Mencius's concept of "the people are the first, the society is secondary, and the monarch is light". Although these political views are quoted from the scriptures and are said by Confucian Confucius and Mencius, if they are known by the court traitors, they will still be remembered. But Ouyang Xuan still insisted on teaching the above content, and the reason was very simple - the Southern Song Dynasty court had neither the will nor the way to make great efforts to save the people from the massacre of the Mongols, so why did it want this rotten regime to work hard?

In addition to teaching political courses, Ouyang Xuan also has to teach professional courses in various classes, although he is not proficient in other professional knowledge except chemistry, but this is only for modern people. Ouyang Xuan's knowledge horizon beyond the millennium still caused great shock and impact to the students. He not only pointed out the way forward for the students, but also broke the shackles of outdated concepts and thinking in their minds. When Ouyang Xuan was lecturing, Du Daquan and Lu Dezhi respectively ordered someone to record the content of his lecture, and bound it into a book together with the lecture content of other teachers, which was carefully preserved as the most important information of the institute and the school. As for why it is not printed into a book, one is that there are not many literate people at present, and the other is that there are no printing conditions in this mountain, and more importantly, these contents are absolutely the highest and most sophisticated technology in this era, and they are not suitable for large-scale dissemination for the time being. Ouyang Xuan's lectures mostly use modern scientific terminology, which is also consistent with the terminology used by industrial, mining and construction companies. At the beginning of the establishment of the industrial and mining industry, Ouyang Xuan fully adopted the modern weights and measures system of "kilometers, meters, centimeters, tons, kilograms, grams" and so on. This system of weights and measures is more suitable for industrialization, and it also invisibly increases the difficulty of imitation and plagiarism by the enemy.

Of course, the diffusion of technology is inevitable, and Ouyang Xuan just hopes that it will come a little later to ensure the overwhelming superiority of the Thunderbolt Army in technology. In order to prevent leaks, Dong Hu and the security team conducted strict background checks and investigations not only on the researchers, but also on the participating students. Of course, the strict review almost buried the talents, once Ouyang Xuan went to the iron mine cave to inspect the production, found that the mine support frame is not only fastened but also extremely fine, so he asked who the maker was. Dang Shijian, the manager of the mining company who accompanied him, told him that it was made by a prisoner named Ni Xianzhong in the labor camp. This Ni Xianzhong was originally a craftsman who made siege equipment in the Chongqing army, and was captured with several craftsmen during the attack on Liuliba and became a member of the labor camp. Ouyang Xuan then ordered Dong Hu to conduct an in-depth investigation of his situation, and after verifying that he was indeed coerced as a bandit, he transferred him to an industrial company and specially approved him as a trainee, and authorized him to select personnel who were proficient in equipment among the captives to engage in relevant research. In this era, the production of siege equipment is definitely a high-tech and delicate work. Of course, Ouyang Xuan didn't ask them to make trebuchets and ballistas, but asked them to try out machine tools. In fact, since the Sui and Tang dynasties, China has had primitive machine tools, but most of them are mainly wood materials supplemented by iron materials, and the structure is also very simple. Ouyang Xuan asked Ni Xianzhong and others to develop and manufacture machine tools for the production of muskets, cannons, and other weapons.

Ouyang Xuan's education and training is not limited to research institutes and schools, and in his opinion, the ideological and political education of the Perak Army is one of the current priorities. For this reason, he also set up a political course in the Perak Army, in addition to the political content taught by him and Lu Dezhi, he also asked Yu Zhu, Huang Dagen, Cao Ergou and others to tell the story of the anti-Mongolian war that they had personally experienced, and bitterly complained about the brutality of the Mongolian army, the weakness and corruption of the traitors in the court, and the deep suffering of the people in the four roads of Sichuan Gorge. Through political education, the political consciousness of the officers and men of Perak has been greatly enhanced, and they have a preliminary understanding of fighting for the people.

The purpose of the existence of the army is to win the war. Cao Ergou was also extremely strict with the Perak Army's concept of discipline and military skills training, which were all high-intensity drills close to actual combat, which made the soldiers complain. The increase in training intensity has also brought about a sharp increase in food consumption, which makes Yang Xiucai, who is in charge of food supply, sad all day long. During the break in the training, Ouyang Xuan did not let the soldiers be completely idle, and let the soldiers have a big discussion in the squad, and after the winners were divided between the squads, they also had to debate between the companies. For example, the first discussion question is: How can we defeat the Wanjiaping bandit gang at the lowest cost and obtain the maximum benefit? The second question is: if you are in the plains, how can you resist the attack of siege weapons and cavalry?

Ouyang Xuan discussed military issues in this way, but he was not afraid of leaking secrets. In addition to the implementation of closed management by the Perak Army, it is also because the strategy of attacking Wanjiaping or going down the mountain to Tuntian can be seen by anyone with a discerning eye. As for what will be implemented after the discussion, it is a secret that only the top brass of the Perak Army knows. In addition to pooling the wisdom of the people and opening up their views, it can also enhance the soldiers' sense of responsibility and belonging. At the same time, through this method of confrontation and debate, we can also discover talented people and lay a solid foundation for the establishment of a general staff department in the next step of the Perak Army, and the transformation of the traditional command of the generals leading the troops into a modern military command system.
