Strictly speaking, the Nanyang Company's trade in Dongchuan County did not comply with the laws and regulations of the Mongols and the Dali State, and was a smuggling activity cracked down on by the Dali authorities, because both of them also implemented a monopoly system for goods such as salt and iron. It's just that Nanyang's products are not only of excellent quality, but also low in price and quantity, which is very beneficial to the local people's livelihood, so they are tacitly approved by the local people. With money in their pockets, more wealth to be scavenged from both new annexes and tribal leaders, and lucrative "road money", these powerful figures naturally turn a blind eye to local copper mining and smuggling trades.

Nanyang's primary target is, of course, copper. It is only the Dongchuan copper ore resources, but the production conditions are poor, coupled with the backward mining and smelting technology, its output and efficiency are not high. After the Mongols occupied Dali, their chicken-killing and egg-taking governance methods made the production of all industries wither. Wuliang Hetai and his Mongol generals were good at killing people, but they knew nothing about the economy. After Banzhou established an alliance with the Dongchuan Wuman tribe, the Nanyang Company immediately cooperated with the villages to open mines. The cooperation model is that Nanyang Company contributes capital and technology, and Wuman cottage contributes labor, and the copper ore produced is initially smelted locally, and then transported to Chongqing Province for further processing and production.

On the one hand, the new management model has made all parties benefit from the interests of all parties, mobilized the enthusiasm of the miners and cottages, and the local officials and the new annexed army have also gained a lot of benefits, on the other hand, the use of new prospecting and mining technology, especially the Thunderbolt army has brought powerful black powder, which has greatly improved the efficiency of mining. The smelted blister copper was transported to Banzhou as soon as possible, and then transported by land to Hejiang County, Luzhou, and transported to Chongqing Mansion for refining. At present, neither Liupanshui nor Banzhou has the conditions for refining copper, and only in Chongqing Province can there be technology and equipment to turn these copper into precision tools, machine tools and other equipment, into lighter and more powerful field guns and warship artillery, and into copper-shelled musket bullets.......

The target next to the bronze is the War Horse. The Dali horse, especially the war horse in its northwest, is extremely good, and is even taller and faster than the Mongolian horse. Before the Mongol army occupied Dali, Dali horses were the most important source of war horses for the Song army, and the Luodian Ghost Kingdom and Luo's Ghost Kingdom, which were located between the Southern Song Dynasty and Dali, made a lot of money by relying on the intermediate trade of war horses. After the Mongol army took control of Dali, all trade in war horses was banned, and although there was still sporadic smuggling trade, the volume of transactions was less than one percent of the previous one. This caused the Song army to lose its main source of war horses, and its combat effectiveness decreased a lot, and it also caused the various tribes of the Luodian Ghost Kingdom and the Luo Ghost Kingdom to lose a huge amount of income, which was also one of the reasons why they hated the Mongol army.

The Thunderbolts are also in great need of horses. One of the consequences of the rapid expansion of the army was a serious shortage of horses, that is, a shortage of war horses, as well as a shortage of pack horses. At present, the cavalry brigades under the three divisions of the Perak Army are short of two-thirds of the horses, and the lack of pack horses for the infantry to tow artillery is even more serious, so that the General Staff has transferred most of the horses directly under the command to the front-line troops. The large-scale economic construction in Jiading, Meizhou, Chengdu, Pengzhou, and Hanzhou also requires a large number of large livestock such as dwarf horses, mules, and buffaloes. Because the demand was too great, the Thunderbolt army had already bought a shortage of large livestock in the grasslands west of the arrow furnace and the grasslands in the direction of Weimao, so Li Shuang wrote to Zhu Zhuozi many times and asked him to think of a way too. Zhu Jiaozi died in his rush to procure war horses and large livestock, and slipped and fell into a cliff while risking crossing an extremely difficult road.

Because the Mongolian army punished the smuggling and trafficking of war horses very severely, and even slaughtered the entire village, the local new annex army did not dare to let the smuggling of war horses go unchecked, so they also tried their best to check at various passes, after all, although money is lovely, but after all, life is not as important. It's just that the junction of Dali and Miaojiang is full of mountains, and the new annexed army can only hold the main passage, but cannot block all the mountain paths. Stimulated by high profits, Nanyang Company was still able to obtain a lot of war horses and large livestock such as ponies, mules, and buffaloes through smuggling, but the price was much higher. Because the mountainous areas of Miaojiang, including Banzhou, were not suitable for cavalry activities, these war horses would be temporarily kept in Liupanshui, where the climate was cool, and after a certain number, they would be escorted to western Sichuan by the army.

In addition to large livestock such as copper and war horses, the Thunderbolt army also had a demand for many resources in Dali. Dali is extremely rich in minerals, in addition to coal, iron and other conventional ores, tin, lead, zinc, gold reserves are quite large. The Mongols did not control the rest of the minerals except for the gold mines, and there was no large-scale mining in the area due to its few uses. However, these things are extremely important industrial raw materials for the Perak Army, such as tin can be smelted into bronze with copper, lead is an important military raw material, and various alloy materials made of zinc can greatly improve the performance of tools and machinery and equipment. Of course, these materials are also available in western Sichuan, but the grade and quantity of ore are much worse than those in Dali, and the cost of mining and smelting is much higher. Naturally, Nanyang Company will not miss the opportunity to obtain high-quality and low-cost raw materials from Dali.

Zhu Zhuozi did a lot of hard work in the early stage, so that the trade volume of Nanyang Company in the direction of Dali showed a blowout development, of which the smuggling trade accounted for nearly half. His sudden death affected these trading activities, and Wang Youfu, who succeeded him, took a long time to become familiar with the situation, although he was experienced. Ouyang Xuan agreed to Yang Yan coming in person this time because he was the most suitable candidate. Because Nanyang's economic activities, especially smuggling, involve the balance of interests of all parties, and a little carelessness will cause Nanyang's early achievements to be wasted. Yang Yan is not only the beloved daughter of Yang Wen, the lord of Banzhou, but also the wife of Ouyang Xuan, the leader of the Thunderbolt Army, so she is naturally the most suitable person to coordinate all parties.

After Yang Yan left Ran Zhong in Banzhou to deal with other affairs of the Nanyang Company, she took Wang Youfu and Du Daquan to Liupanshui, accompanied by an armed company of the Nanyang Company. At present, the Nanyang Company has nearly 2,000 people, including nine armed escort companies, more than 300 large and small ships, and more than 1,000 horses and mules. The company's headquarters is still in Chengdu, but most of the staff are in the Miaojiang area. Since the road to Liupanshui had been widened and repaired, and there were trading posts and post stations of the Banshu army on the road, Liupanshui was reached five days later.

In Liupanshui, Yang Yan met Luo Suo's father and son and a group of clan leaders of the Luo Clan Ghost Kingdom, and met with representatives of the Wuman tribes in Dongchuan. On behalf of Banju and the Perak Army, she reaffirmed the validity of the agreement with the tribes and pledged to continue to increase military, economic, educational, and medical support. Her commitment dispelled the doubts of all tribes after Zhu Zhuozi's death, and made the next negotiations between Wang Youfu and Du Daquan very smooth.

After dealing with a series of things, it was already the beginning of December, and Yang Yan returned to Longyan City to meet Yang Bangxian and set off for Chongqing Mansion. Yang Yan was already pregnant in April at this time, so it was really not suitable to continue to run around, while Yang Bangxian sought Yang Wen's consent and continued to follow Ouyang Xuan to learn the advanced governance experience of the Thunderbolt Army. When the brother and sister returned to Chongqing Mansion, it was close to the Spring Festival.
