The strategic focus of the Qin State was determined for a while. It was mainly Shang Wen who advocated cutting military spending. In order to reduce government expenditure and increase social infrastructure construction. But Qin's military still could not be completely abandoned.

In particular, the media exposed the Baihe incident in which Qin was wiped out in the north with a force of nearly 200 people. Because the location where the bones were found at the time of the incident was close to the White River, the Qin State named a certain river in the north. That's why it's called the White River Incident.

The exposure of the Baihe incident made the Qin state once again reconsider the threat from the north. Although measured from the map, it was impossible for the Huns to move south on a large scale, and the Huns were about more than 3,000 li away from Xianyang in the Qin state. This distance was enough to keep the capital of Qin safe. However, after all, the Xiongnu had evil deeds first, and the Qin State did not want to see its neighbors full of malice. In short, under the influence of successive victories abroad, the people of Qin have formed a concept. That is, either to be a weak neighbor exists. This neighbor is Qin Guo who will clean up whenever he wants, and accept all of Qin Guo's unreasonable demands.

Either it will be completely exterminated by the Qin State. This is a concept of Qin's foreign warfare. This concept is extremely overbearing and uncompromising. The belligerence of the Qin State was thoroughly stimulated. Because war is good for all.

"Our country has twice used troops against the west. The recent events at the White River show that the Huns are re-emerging and that they will once again intend to move south. It has been learned that China's military strength in the north is very limited. The Qin army as a whole deployed more than 30,000 regular troops in the north. Its number is not as good as the 50,000-strong Zhao army. This situation is worrying for our people. A reporter said.

"Excuse me, can a regular army of more than 30,000 people guarantee to prevent the Huns from moving south?" Reporters have raised questions about Wang Jian, chief of the General Staff. And Wang Qian's answer was.

"Of course not." Wang Jian replied.

"The Huns came and went without a trace, and we do not yet have a concrete defensive line in the north to defend them from going south. But instead of defending, it is better to increase troops and completely destroy them. I think so. Wang Jian said directly. The reporters quickly wrote down what Wang Jian said.

The subsequent newspapers began to figure out what Wang Jian meant.

"The Chief of the General Staff intends to increase the number of troops in the North. Completely eliminate the great calamity of the Xiongnu in the north. The title reads. In this way, Wang Jian meant to use troops in the north. For this reason, Meng Tian in the north began to hold a meeting after learning of this news to discuss how to innovate tactics.

As for the previous train strategy, Meng Tian believes that it is still necessary, after all, it is built on civil infrastructure, and so many railway lines are being built in Qin. There is no problem with that.

For new tactical issues. There are many proposals, such as focusing on the transportation network. In particular, the emphasis is on mobile operations. The transportation network relies on the road network to divide the northern grasslands one by one. Then build a defensive point. Auxiliary mobile defense. In the end, all the Huns in the road network were cleared, and one by one, one by one. In fact, there is not much innovation in such tactics. But how effective it will be, no one knows. But these were all built on what was already in the north of the Qin army. As for the future, it is not clear what these troops have been stationed in the north for a long time.

In comparison, on the contrary, Xianyang's staff was somewhat innovative, and Wang Qian's disclosure in the media made the Qin army bound to increase troops in the north. The White River incident, coupled with the statements of the Chief of the General Staff, was enough to define the strategy.

King Qin also means this, that mainland policy already has a large market. In contrast, the interest in the ocean is not very great. Coal and iron ore on land have only just begun, and the expanding demand for steel in the Qin State has already stimulated this demand. In particular, coal and iron ore are concentrated in the north, which creates an inertial thinking, so there must be a large number of coal mines and iron ore in the grasslands where the Huns gathered. It is this kind of inertial thinking that has contributed to the prevalence of this continental policy.

It can be said that the rise of mainland policy is the representative of industrial civilization, especially with steel production as a civilization. The social demand for steel will inevitably lead the Qin State to the north. This is the inevitable choice of the Qin State. Opposite. Shangwen's marine demand is not yet so great. Or maybe the underlying ocean demand pattern hasn't been fully revealed. There is a potential consideration in Shanven's maritime policy, and that is oil, not coal, and steel. However, the places where fuel was used in the Qin State were mainly concentrated in the Guanzhong region. The oil from the north of Qin and the shallow oil from Qi were enough to support the use of motor vehicles in the Guanzhong region.

In other regions, especially the Xinjian Prefecture of Qin, a large amount of animal power was still used as a means of transportation. Even trains run on coal, not diesel. In this way, the transportation importance of the sea is far less important than that of the northern land. Under these circumstances, the land policy of the North began to be finalized. There is no big market for ocean policy for the time being.

However, Shang Wen advocates that the coming year will still be a small fight. In other words, the army was asked not to use a large-scale army, but to use a new army and equip it with new weapons to fight the Xiongnu, which was also in line with the characteristics of innovative tactics. Because, at this time, the Huns had changed the previous combat method of direct collision with large corps, and changed to wolf pack tactics and guerrilla warfare in all directions. In this way, the Huns' combat methods became more and more flexible, while the Qin army's combat methods were somewhat rigid and conservative. Even if flexible tactics such as cavalry were used, the cavalry was a formed search, and at the same time, the Huns took advantage of the grassland combat advantage and tried to hide their own characteristics as much as possible, which made the Qin army have signs of being difficult to deal with for a while. These are still present in the report. But this point has been noticed by the staff officers of the Qin army.

Just when the attention of the Qin State gradually shifted to the north. A new type of aircraft is being tested at the flight test site of the Qin State. This was the early helicopter.

The emergence of helicopters is not accidental, with the popularization of propeller technology, the folk have also imitated, especially a kind of bamboo dragonfly toy from the Qi country, this toy is actually a propeller test object, but in the hands of a very accidental child became a toy, and then this toy immediately reversed to the Qin State. Inspired by this, Qin scientists began to notice another mystery of the bamboo dragonfly, hovering, moving forward, and flying upside down. If you use this as a flying machine. A completely new aircraft is necessary.
