Just when the banks in the coastal areas organized expeditions to venture everywhere on the ocean, looking for opportunities to make a fortune, the Bank of Shanxi, which was deep inland, began to march to the northwest according to Zhu Youxiao's guidance, covering the entire northwest and even as far as Moscow.

In history, Lu silk is a very good silk products, its sales throughout the country, Shanxi merchants just started with the sale of Lu silk, with the continuous expansion of the market, raw materials are naturally not enough, businessmen from the south to Shanxi trafficking, and then the silk trafficked, to later not limited to silk such as Lu silk, but also includes the south of tea, porcelain, the north of camel hair, cashmere, sheepskin, cowhide, etc., as long as the things that can make money are sold, and gradually formed a large scale, later generations of Ningxia, Zhangjiakou, Baotou and other places have left their footprints.

With the continuous westward expansion of the Ming army, the footsteps of Shanxi merchants are also with the expansion of the army, especially in the Western Regions, with a large number of soldiers on the spot to farm the troops, but also to make the caravan of Shanxi people where is very active, the original use of horses to traffic the need for feed labor costs are huge, and later with the development of the pot camel machine, it has gradually replaced the use of some horses.

The implementation of Zhu Youxiao's expedition policy has broadened the horizons of Shanxi businessmen, and many things that were originally inconvenient for long-distance transportation began to be processed into canned food on the spot with the successful development of canned products, or processed into finished products that can be stored for a long time, which makes a large number of materials that can be trafficked, and these processing plants need a certain amount of financial support, and Shanxi Bank began to invest in a large number of these processing plants.

The students who graduated from Daming Institute of Technology, through countless experiments on packaging paper, developed a closed paper bag that can be used to package cooked food, the inner layer is packaged with edible beeswax-soaked oil paper, and the outer layer is vacuum sealed with this paper bag, according to the principle of bellows, a vacuum sealing machine is manufactured, so that the food under this packaging can be stored for a long time. This patent was bought by Shanxi Bank, and then began to be used in a large number of processing plants around the country, so that Shanxi Bank got three new industries at once, food deep processing, new packaging paper, vacuum sealing machine, so that the value of their goods got a higher grade, and earned higher profits.

Then there is the Shanxi Bank to assist the Ming Dynasty in the country to set up a post office, this is Zhu Youxiao has been considering the problem, although there were all over the country post stations in this work, but the cost is still a little too high, Jin merchants and Hui merchants business outlets all over the country, they also have a lot of things to transport, bulk commodities can naturally be transported through the caravan and convoy, but many small things, including letters and other low-value things are not cared for, now the flow of the country's population is very large, there are a lot of things that need to be sent, If you still rely on the post station to do these jobs, you have to add a lot of manpower, and the cost will have to increase more, so Zhu Youxiao let the Daming Royal Trading Commercial Bank and Shanxi Bank and Huishang Bank set up the Daming Post Office.

The duty of the Daming Post Office is to be responsible for sending all the letters in the country, no matter far or near, all of them are five copper coins, and the letters mailed back by the soldiers are free, so Zhu Youxiao made a fresh decision, the mail truck that transports the letters can advertise for these three commercial houses for free, and can also accept the advertising business of merchants, workshops, and factories. Secondly, in order to save the workload of the post office staff, according to the practice of later generations, each province was numbered, and the envelopes were printed and sent to each province to use the envelopes of each province, so that the sorting speed was very fast, and as for the city and county to the village, it was relatively less, especially in the countryside, and the letters were sent to the school and passed by the students. Small parcels are billed by the pound, and the price is the same, regardless of the distance, and valuables are charged separately. At first glance, these behaviors are not profitable, but after careful analysis, these have great profits, especially in advertising, which contains unlimited business opportunities, depending on how each business bank operates.

Since ancient times, Hui businessmen have traveled all over the country, and they will participate in any business meeting, and Zhu Youxiao does not need to provide them with any advice at all. On the one hand, the Hui merchants traveled all over the world, and the value of commodities everywhere was under their control, and secondly, in their eyes, there were opportunities everywhere, such as machetes, iron pots, copper spoons, bows and crossbows, and even shovels, hoes, sickles and other things needed for the exploration of the three major coastal banks, as long as they were shipped in large quantities, they could manufacture or sell them.

Ma'anshan is a famous iron ore base, Huishang Bank invested in the construction of a steel mill here, and it is a very large steel mill, and then there are small workshops that have sprung up like mushrooms after a rain, all kinds of iron products emerge in endlessly, attracting the expedition teams of the three major coastal commercial banks to come here to purchase, and gradually formed an iron distribution center.

In order to ensure the quality of the problem, there is also a special department responsible for quality, called the Quality and Technical Supervision Association, any individual or partner who wishes to open a workshop, factory, must be registered here, although it belongs to the private organization, but it is the most authoritative technical organization here, where there is no quality certification certificate for the product, it is difficult to develop here, because no one supplies raw materials, no one buys products. In order to expand its influence, it also came up with an ingenious advertisement, as long as there are counterfeit and shoddy goods in the factories or workshops that have passed the certification here, the Quality and Technical Supervision Association will be responsible for compensation, and it is double the compensation. As for where its funds come from, this is very simple, except for charging a little industry membership fee from the enterprise, that is, delisting and taking out the quality certificate, so that the enterprise has no way out except for bankruptcy.

In fact, the idea of the Quality and Technical Supervision Association is Zhu Youxiao to Anhui Buzheng envoy, because Zhu Youxiao knows that Anhui people are too smart, if there is no previous word "too", Zhu Youxiao will not come up with this idea, people are too smart will return to opportunism, and the most taboo in industrial production is opportunistic, it must move forward step by step, so as to lay a solid foundation for the future industrial base. In later generations, Anhui had too many national initiatives and originality, but in the end there were very few well-known enterprises in the country, the reason was that they were too smart, too focused on immediate interests, and lost the best opportunity for development. Hu Xueyan, a famous red-topped businessman in modern history, had a very good grasp of the first few speculative opportunities, but excessive speculation caused the final bankruptcy. The world's first VCD after the reform and opening up was made in Anhui, and the ending was also sad. Now Zhu Youxiao has set up a cage for the smart Anhui people in advance, so that those who are too smart will not dare to take shortcuts.

When the expedition team with the support of the major banks attacked everywhere, as the boss of the Tenglong Bank and the Ming Royal Trading Company naturally could not stand still, the Fushun Coal Mine, Anshan Iron Mine and Anshan Steel Mill in the Northeast are the most advanced in the Ming Dynasty, it is also the largest investment project of the Tenglong Bank and the Ming Royal Trading Bank, the steel it smelts is the best in the Ming Dynasty, and it is also the most varied, so the iron tools made here are the most advanced in the Ming Dynasty, and most of the alloy steel is used to make cannons and barrels, equipped with the soldiers of the Ming Dynasty, The rest is used to make pot camel machine, water wheel and other goods, the pot camel machine made here is also mainly for the army, so its power is relatively large, and the fuel used is no longer firewood and other sundries, the selection of high-quality coal and heavy oil, so its efficiency is much higher than the general pot camel machine, and the operation is much faster.

After Niu Jinxing arrived in the capital, in addition to reporting to Zhu Youxiao about the situation along the way and the development in the Americas, he also thought that Zhu Youxiao raised the problem of the slow speed of warships and the inability to find suitable fuel on the sea. Therefore, Zhu Youxiao asked Yu Hualong to drive all the warships and merchant ships to the Liaodong Peninsula after the New Year, where all the steam engines were replaced with coal-fired boilers, so that as long as the amount of coal needed per 100 miles was calculated, enough coal-carrying ships could be equipped according to the distance.

By the end of March, more than 260 warships and armed merchant ships of the Ming Royal Trading Company that had been fully prepared set off from the port of Tianjin, this time Zhu Youxiao suggested that Niu Jinxing and Yu Hualong sail eastward along the 50th parallel of north latitude, and it would take less than three months to reach North America. When you get there, see how Zhao Shujiao, Fu Guan, and Man Gui are doing, and then you can go south to Yidao, Li Shaoxian, and Qian Shoulian, and give them some help as much as possible, and then you can return the goods there along the route you came back last time. This time the fleet brought more than 5,000 merchants and craftsmen who wanted to take risks, and when they returned, they could also bring back people who were not accustomed to being there, and there would be such voyages several times a year in the future, to supplement the Ming people there, so as to occupy a foothold.
