Ouyang Xuan proposed the measures, everyone has no opinions, and they also put forward relevant measures in combination with their own division of labor. Li Shuang proposed that "water conservancy is the lifeblood of grain production" and that it is necessary to take advantage of the time when the water is dry and the farmers are slack to dig more ditches and open more ponds, which is not only conducive to drought and flood control, but also restricts the activities of the Mongolian cavalry. The excavation of the ditch seems to reduce the area of grain planting, but the water surface can be used to raise fish and shrimp and plant crops such as lotus root and taro, which also increases the moisture retention capacity of the land, and the silt in the ditch is also an excellent fertilizer.

Li San'er, who was in charge of industrial production, put forward a request for the construction of hydrochloric acid, nitric acid, soda ash and caustic soda plants. These raw materials and sulfuric acid, commonly known as "three acids and two alkalis", are important raw materials for the chemical industry, and it is naturally not difficult for Ouyang Xuan, a chemical professional. Long before the Thunderbolts descended, under his guidance, research institutes and industrial companies developed production methods and production processes, but they could not be manufactured due to the lack of key raw materials. Now the territory of the Thunderbolt Army is more than ten times larger than that of the Jiguan Mountain area, and through its own mining and caravan to obtain key raw materials, large-scale production is naturally on the agenda. For example, in Yixing Township, near Wugen Mountain, large-scale production began. This miscanthus is the sodium sulfate in Ouyang Xuan's mouth, and it is also an important chemical raw material. As for why Li San'er didn't mention the production of sulfuric acid, it is because most of the iron ore in Jiguan Mountain is siderite with more sulfur, which is still a large inventory as a by-product of ironmaking, and a large amount of sulfide can also be collected to make sulfuric acid when coal is smelted into coke.

At present, the trade of the Perak army is mainly based on the tea and horse trade with the Fan and Yi districts. Although the volume of tea is large, Yazhou is the main producing area, and Meizhou and Jiading also produce a large number of tea, and the tea of the Perak Army competes with it and does not have much advantage. Although porcelain and iron farm tools were also lucrative, the trading volume was not large. It is not too much of a problem to buy mules and horses on trade profits, but it is not realistic to buy expensive war horses. In fact, the money earned by the Thunderbolt Army merchant team in a year could not buy the 400 war horses of the steppe tribe captured last time. Among the industrial and mineral products of the Perak army, although the output of coal and cement is large, it is not suitable for long-distance transportation, and there is no market demand, and copper, lead, mercury and other products can be sold at a good price, but the output is not enough even for the Perak army itself. Although iron is produced in large quantities and in stock, it is not easily sold as the most important raw material for the military industry.

At Ouyang Xuan's request, Li San'er is now actively developing and producing consumer products, expanding the market from Jiading to Chongqing and even Dali, and even dumping them into the Mongol-occupied areas if possible. In addition to the alkali for washing clothes, the focus of the first products to be developed is glass. This thing looks shiny, and if it is made into tableware, it will definitely be sought after by dignitaries. Ouyang Xuan firmly believes that "the money of the rich is best earned", and they are the main force in the trading of goods. Of course, there is another important purpose for the priority development of glass, that is, to make telescopes, and there is no doubt about the military role of this thing.

Li San'er talked endlessly, but it caused the four military personnel to be unhappy. In the eyes of Cao Ergou and other military figures, the production of firearms and other military industries is a major matter, but Li San'er's speech has nothing to do with it, but focuses on how to make money, and his mouth is full of copper smell, which is really not like an official but like a businessman. Even Yu Zhu, who has always been calm and stable, asked whether the production of firearms is lagging behind because not enough attention has been paid to it, and whether the management of this military factory needs to be improved. These interrogations made Li San'er blush.

In fact, Cao Ergou and other high-ranking military personnel also knew that the affairs involved in the relocation of the factory were extremely complex, and Li San'er and his thousands of people worked day and night, which was really very hard. However, after the expansion of the army, the shortage of firearms in the brigades was too large, which really affected the training. What if the Mongols called at this time? I couldn't help but complain. Ouyang Xuan knew Li San'er's difficulties best, so he pressed the controversy immediately, and deployed the firearms of each brigade to give priority to meeting the needs of key defense and combat units. As for the shortage of firearms in other units, we have to wait slowly.

The construction of this industrial system will not happen overnight. Taking the Dayi Military Factory as an example, this is by no means as simple as moving the military factories in Wanjiaping and Liuliba down the mountain, and it is not only an expansion of the scale and increase of manpower, but a large-scale upgrading of the entire military production system. It is no exaggeration to say that it is very different from the original military factories in terms of production equipment and power, personnel management, technical standards, and quality control. Taking the production of gun barrels as an example, in the past, it was produced by casting method, which was to pour molten iron into the mold; Now it is improved to the boring and milling method, that is, the solid round iron column is machined into a barrel with a lathe. The barrel produced in this way is of excellent quality and has a low defective rate, but it is necessary to make a fine iron lathe first, and a forging press is also needed, both of which need to be driven by power, so it is necessary to hold back the water and build a dam to obtain enough water energy. This is also the reason why the Dayi Arsenal will not be put into operation until at least early next year.

In Ouyang Xuan's plan, the first-line troops of the Thunderbolt Army will gradually be equipped with new types of artillery, muskets and grenades, and some of the replaced weapons will be used to equip the second-line troops, and some will be sold to friendly forces. The arms deal has never been a simple sale, but a means of building political alliances. Of course, the sale of weapons is also due to lack of money. Especially in the recent rapid expansion of the Thunderbolt Army's various undertakings, large-scale construction and army operations require a large amount of funds, which makes Ouyang Xuan, Li Shuang and others have a headache, and naturally they will not let go of the profiteering industry of arms trading. With the support of sufficient funds, more and more R&D and technology investment will be made, and more new technologies and new products will be developed. As for the inevitable proliferation of technology, it is possible to delay it as much as possible, but it is absolutely impossible to prevent it. Based on this line of thinking, Ouyang Xuan's idea is to form a virtuous circle of R&D system and a perfect industrial foundation as soon as possible. Even if the Mongols stole firearm technology, they would not be able to produce it on a large scale, or the production would be different from the Thunderbolt firearms. It will still be crushed by the advanced technology of the Thunderbolt Army, and it will still be beaten by the Thunderbolt Army's strong production capacity.

The final topic of the joint meeting was to discuss how to rescue the cannon casting technicians who had been detained by Yu Xing and his son. Before the meeting, Dong Hu had already reported the situation found by the scouts to Ouyang Xuan. After Yu Dazhong led his army to attack Pengshan and failed, he did not return to Jiading, but stationed in Meizhou City, and the technicians were imprisoned in a dock fort in the west of the city. The participants all agreed with Ouyang Xuan's opinion, believing that no matter what the cost, they must be rescued. There is only a slight controversy about the way it is adopted.

Lu Dezhi believes that although Yu Xing is only the nominal top boss of the Thunderbolt Army, if he uses force to recapture the hostages, he will be suspected of rebelling against the imperial court in the eyes of the world. The Thunderbolts must not stand on the opposite side of morality, but still have to take the road of property redemption, and the price can be negotiated slowly. Since Yu Xing can ask for a price all over the sky, the Thunderbolt Army can bargain on the ground. Lu Dezhi's opinion was supported by Li Shuang and Huang Dagen, while Yu Zhu, Li San'er and others could not be denied, but Dong Hu and Cao Ergou resolutely opposed this approach. In their opinion, Yu Xing's father and son are bullying people with their power, and they are getting more and more inches, and this unhealthy trend cannot be long. During this time, Yu Xing's actions made Ouyang Xuan hate these corrupt bureaucrats more and more, and he decided that he would never let Yu Xing's father and son get their wish, but sent special forces to rescue the hostages. It's just how to save it, and then add it up. At this time, Yang Xiucai, who had been silent and did not speak, said slowly: "Why don't you pretend to be a Tartar cavalry to rob people?" ”
