Scientific research and teaching made Ouyang Xuan passionate, but it was always interrupted by sudden military and political affairs. Although the daily government affairs of the Perak Army are under the control of Li Shuang, and the military affairs are in charge of Huang Dagen, Cao Ergou, Yu Zhu and others, the volume of military and political affairs has increased geometrically after going down the mountain, and the difficulty of governance has also increased exponentially. Although it is advisable to hold fewer meetings and short meetings, there are still many meetings waiting for Ouyang Xuan. This is because the matters to be decided by these clubs are so important, involving major politics and people's livelihood, and related to the fundamental governance of the Perak Army. In early June alone, he presided over two joint military-political meetings, but fortunately the lengthy meetings were not in vain, and several key matters were decided.

The first is the naturalization system. At present, the population under the rule of the Perak Army has reached 200,000 people, and in addition to the natives of western Sichuan, there are also many immigrants from other places, and there are not a few people from Yibo. Attracted by preferential policies and a stable environment, the population under the rule of the Perak Army continued to grow. Who is a citizen of the Perak Army and who can enjoy the preferential policies of the Perak Army has become a controversial topic. Ouyang Xuan adheres to the idea of integrating Huayi, believing that as long as they live in the territory and are registered, and recognize the concept of the Perak Army, they are all citizens of the Perak Army, and they can naturally enjoy various benefits. His idea was considered too lenient by others, and the plan that was ultimately approved was much more stringent.

The Military-Government Joint Conference defines a Thunderbolt Citizen as a citizen of the Thunderbolt Army who agrees with the Thunderbolt Army's philosophy, is proficient in Chinese or has made contributions, fulfills the obligations of the Thunderbolt Army, and is registered as a Thunderbolt Citizen. This definition excludes a significant number of people from citizens, especially the people of Yibo and prisoners of war in labor camps. For those who do not have citizenship, the joint council has also made a provision that they can be registered as registered citizens after they have lived in the Perak military area for three years and can speak Chinese. The joint conference also explained the circumstances of contribution, that is, elders with skills in politics, military, economics, science, medicine, etc., can become citizens even if they do not speak Chinese. The Yibo warriors in the regular army of the Perak Army met this condition.

The second is the acre system. When they first descended from the mountain, the Perak Army had already adopted the system of acreage and achieved the goal of having their own land for the cultivators, and even attracted displaced people to settle land by not paying grain, and rewarded meritorious and disabled soldiers with land. This system presupposes the existence of a large number of ownerless land, but it is also controversial. Jiang Yuan Changyuan betrayed because he held thousands of acres of land deeds, but was not recognized by the Thunderbolt army, and tried to defect to the Mongols in order to regain land ownership. In addition, the land sale, inheritance and use are not clear, so Li Shuang took the lead in formulating the new land acre system.

The new land acre system still adheres to Ouyang Xuan's idea of equalizing land and preventing land annexation, and explicitly does not recognize the title deeds of barren land. The cultivated land under the administration shall be subject to a parallel system of contracted land and permanent farmland. That is, if the land is fertile and thin, each adult man may be granted 30 to 100 mu as contracted land, and the child and woman shall be halved, and adjusted according to the increase or decrease of the population, but each household shall not exceed 1,000 mu of contracted land. Contracted land is public land, which can only be cultivated and cannot be inherited. It can be inherited and bought and sold and used as private property as a permanent field. In addition to buying and selling, the main source of Yongye Tian is rewards for military merits and scientific and technological inventions, or compensation for bereavement and disability, and each household shall not exceed 1,000 mu.

The third is grassroots governance. Chang Yuan's rebellion was mainly due to his unsatisfied personal desires, but it also reflected the weakness of the Perak Army's grassroots governance. If his superiors could be more refined, if the management system could be tighter, Chang Yuan would not have formed a gang, and then coerced so many people to participate in the rebellion, the so-called "the main general is incompetent, exhausting the three armies". The unanimous opinion of the top brass of the Perak Army is that it is necessary to strengthen the management of the grassroots units, especially the selection and use of grassroots officials and managers.

The most basic units of the Thunderbolt Army are the cantonment points, and the higher ones are the townships and counties. According to the new system, in addition to the county heads, each county also has six sections, namely, soldiers, criminals, households, rites, workers, and officials, who are respectively responsible for military armament, judicial and criminal prisons, finance, taxation, commerce, education, public health, industry and mining, and official management. Most of the townships are located in large reclamation points, and in addition to the township chief, there are only four officials: soldiers, households, ceremonies, and workers. The cantonment points are still set up according to the previous setting, and the cantonment chiefs are still elected by the people, but they must meet the new standards. In view of the fact that the Perak army will be in a state of war for a long time to come, the new system clearly stipulates that the tun chief and the township chief must have military experience and be literate. In the selection of county and township officials, in addition to assessing the corresponding professional knowledge, those with military experience are also given priority.

Fourth, there is the issue of military system. At present, the Perak Army implements a combination of a standing army and a basic militia. The joint meeting held that there should be a moderate distinction between the standing army and the basic militia in the integrated mode of farming and warfare. Zeng Yong and others drew on the military system of the Tang Dynasty and the recruitment system commonly adopted by the Song army, and put forward a plan for the professionalization of the standing army and the military of the basic militia, and proposed to control the number of militias, which was approved. At present, there are only 5,500 people in the four brigades of the Perak Army's standing army plus the troops directly under the General Staff, but there are as many as 50,000 militiamen participating in the training, including many weak-crowned young men and gray-haired old men.

According to the new military system, the number of standing armies remains unchanged, and weapons and equipment are still provided by the quartermaster departments. Soldiers of the Standing Army are in charge of training and warfare, and are no longer engaged in productive activities unless there are special circumstances, and the land allocated to them is cultivated by the village where they are located, and the labor service of their families is reduced. According to Zeng Yong's suggestion, the number of basic militia members was controlled at about 20,000, and the model of integrating farming and warfare was still adopted, and the labor required by them was reduced, and the necessary clothing, food, cold weapons, and weapons were purchased by themselves, and the firearms needed for weekday training and wartime needs were uniformly provided by the quartermaster department.

The new military system seems to be a loss for the soldiers and the people, but it is not. Although the people under the rule of the Perak Army did not pay for food, they still had to bear a lot of labor in the farms, such as bringing their own food and tools to build roads, ditches, and forts, which was also very heavy. It's just that these labors are really not worth mentioning compared to the murder and plunder of the Mongols and the oppression of other state officials. Ouyang Xuan and other high-ranking Thunderbolt Army leaders also did not want to increase the burden on the people, but at the current level of productivity, only in this way could they maintain operations and fight against the murderous Mongols.

As soon as the order for the new military system was issued, the soldiers of the standing army were in a stable mood, which caused a panic in the ranks of the militia. For no other reason, there are too many people who want to stay in the basic militia. According to the Perak Army system, even if you do not become a standing soldier, there are many advantages to becoming a basic militia, which means that you have the qualifications to be an official, economically it means that you can be exempted from hard labor, and it also means that you can obtain Yongye Land through military exploits. Proceeding from combat effectiveness and military needs, half of the establishment of the basic militia was allocated to the industrial and mining industries and the reclamation points along the river, while the rest of the localities were allocated a small number of places. As a result, the rest of the cantonment sites have asked for an increase in the number of staffing places, which has made Yu Zhu, who is in charge of this matter, anxious and in a hurry for a long time.
