The Qin army's tactics in the northern and western regions were carried out by dispersing forces, while in the north, the Qin army was building a new offensive and defensive system, which was both a civilian and a military facility. This kind of facility is the railway "Great Wall." ”

The King of Qin spent two months inspecting the entire north. And the situation in the north is basically very optimistic. However, because of the main forces of the Qin State, the materials were mainly concentrated in the Western Regions, and the war situation in the north could not be expanded for a long time.

But Meng Tian soon noticed a new strange phenomenon. That is, compared with the military investment of the Qin army, the investment in domestic infrastructure is far greater than the military expenditure. Not only did the central government increase investment in infrastructure, but even the newly established state governments issued bonds and borrowed heavily to build various infrastructure to attract investment. Among these investments: In particular, the proportion of railway investment is quite large. According to a survey conducted by Qin's domestic "Finance" magazine, railway investment has always been a hot spot for investment.

The state of Qin was attracting a large number of investors to participate in it by selling large quantities of cheap land. Railroad stocks have also risen wildly. There are currently three major railway companies in the Qin State. They are the Wenyang Railway Company, the Royal Railway Company, and the Li Baiwei United Railway Company. Its Chinese Yang Railway Company has the largest market share. Almost sixty percent of Qin's railway construction projects were under its control. The Wenyang Railway has an absolute advantage with the help of the alliance of banks and iron and steel enterprises, and the remaining royal railway companies can get the remaining share of the market by relying on the Qin Wangqin project, but the private investors, especially the traditional non-governmental forces of the Qin State, the joint railway company formed by the Li family, the Bai family, and the Wei family, once occupied the remaining railway share with the royal railway company.

Behind the railway is the extreme expansion of the monopoly form of the Qin State, but this expansion is still very suitable for the Qin State at present, because the Qin State needs these monopoly organizations to build the infrastructure of the Qin State, if the anti-monopoly at this time is equivalent to knocking off his own arm, this practice is very undesirable, and the large industry of the Qin State has only just begun, that is, it is the time when monopoly capitalism needs the most for the overall economic development of the Qin State.

Based on the massive rise of railway construction, especially in the northern part of the Qin state. Wherever there is ore, there is a great demand for railways. Meng Tian's idea was whether he could expand his influence on the northern war based on the railway.

"The king, the last general thinks that the grassland warfare, especially the battle in the northern desert, requires crossing the great desert, and if you use horses, it will require a lot of pressure, but if you build a railway. It can greatly save logistical pressure, not only that, after connecting the north-south traffic arteries. It is possible to lay railways in the east-west direction. In this way, our army used the railway as the line of defense to compress the living space of the Xiongnu step by step. Meng Tian said as he drew one railway concept after another on the big map.

King Qin nodded, expressing his approval of Meng Tian's idea.

"But, General, the construction of the railroad requires a lot of money, and these sources of funds are not a simple matter. Moreover, the value of building a railway requires a lot of economic value to support it. If we build a railway to transport cattle and sheep, then the economic value will ・・・・・・. Meng Yi put forward his own opinion. Perhaps it is related to his long-term economic work as a deputy prime minister. Meng Yi's views are mostly from an economic point of view.

"It's true, if it's purely military, the widow can repair it, but the prime minister sent a telegram a few days ago saying that he would further reduce military spending. The widow thought about it and thought that the prime minister's decision was not unreasonable to cut military spending. King Qin said.

Meng Yi nodded as he spoke. But Meng Tian had obviously thought of this layer. Meng Tian had been by Shang Wen's side and deeply felt the influence of that economic and scientific atmosphere. At a time when the North bears such a burden. He's also constantly learning. For example, he studied all kinds of scientific knowledge, and also read some economic theories and business management. Not only that, but when he was patrolling the troops, he often visited major enterprises in the two states. This gave the general a further understanding of his country's economy.

This is something that the general thinks can be solved. There are many mineral resources in the north, and Simon Prefecture is rich in rare earth resources, iron ore, and coal. There are also in Dongmeng Prefecture. There is also the appearance of gold in places close to the mountains, which can be connected to trains, and in Mobei, there is also such an abundance of iron ore. If we publish this information and auction off those areas, we can get the railroad there. In order to ensure their safety, we can adopt the strategy of mobile defense, using ironclad locomotives for mobile defense and increasing troops. Then rely on the railroad to extend our defenses. In this way, the goal of besieging the Xiongnu and developing and strengthening the strength of our army was slowly achieved. Meng Tian said what he thought.

"Yes. Yes, this is a good idea, get a report out and let the prime minister study it. We have to do it. King Qin said.

Meng Tian's idea was actually formulated according to the current strategy of the Qin army in the north. The northern part of the Qin army as a whole was in an active defensive state. Don't look at the fact that the Qin army can launch a small-scale attack. But the whole is in a state of strategic defense. Mainly because the cost of a one-time solution to the northern nomads is simply too high. Moreover, the Qin State continuously launched foreign wars, and each foreign war required huge financial expenditures, and the Qin State supported its foreign wars in the form of continuous issuance of national bonds. This model developed benignly under Shangwen's control. And many times for the purpose of self-reduction of military spending to control, for the north, especially against the Xiongnu. Its economic value is far from rising to the level of strategic value, so the overall allocation of military spending is very small.

This directly causes the north to be in a state of strategic defense, but Meng Tian believes that since it is defensive, then it must be actively defended. Since the military spending is small. That can make full use of private capital and private resources to achieve the purpose of this kind of defense and siege. This is a way of organically combining the military and the economic.

Take advantage of the potential mineral resources in the north to lure more people to invest. The construction of railways brought about by investment is bound to be in it, and there is a large potential military value behind civilian facilities. That's what Meng Tian thinks. Use of civilian facilities for military purposes. Putting military facilities into the civilian market. The use of these facilities is then reached in the name of borrowed protection. This account is a very cost-effective calculation, and it can be said that the military can achieve its original strategic goals without paying a penny.
