After studying and figuring out ways all night, but after dawn, Oluyumov, who had not thought of a good solution, shook his sleepy body and was about to take a nap, when the adjutant ran in in a panic and shouted: "Oh no, no good!" ”

"What's the panic, is it that the Chinese army is going to attack the city!"

The adjutant nodded, and Oluyumov said disdainfully: "Don't you just attack the city, just let them defend it well, don't drop the chain like last night!" ”

After finishing speaking, the adjutant who thought he was going out didn't go out, holding back and not knowing what to do, and finally, the adjutant still said: "Your Excellency Commander, you better go out for a while!" ”

"Get out!" Shaking his head helplessly, Oluyumov still went out, on the observation post of the fortress, he saw what the adjutant said about heroism, around Chita, within a range of 10 kilometers, the Chinese army put out a defensive camp, there was no intention of attacking the city at all, but after a careful look, the opponent's artillery unit was ready, just on the eastern side, there were thousands of artillery pieces seen, and the number of artillery around the entire Chita can be imagined.

Artillery is the king of infantry, any infantry without artillery, the combat effectiveness will drop a lot at least, but such a huge artillery force, in front of the Russian army, all the Russian troops who saw all this are swaying, they don't know what to do, although, Chita is a strong city, is a fortress city, but the other side has too much artillery, tens of thousands of artillery, if there is no day and night bombardment, how long can Chita last?

For the first time, Oluyumov did not reprimand the adjutant, he was speechless. Isn't it just a fortress, why would the Chinese move such a big formation?

The Chinese army got up early in the morning today. After the artillery was arranged, the first round of artillery preparation began.

The Mongol Northern Army except for guarding a small number of troops in Mongolia. The rest of the army is all gathered in Chita, leaving aside the 2 corps responsible for blocking possible reinforcements, in a small Chita, gathered 400,000 troops, close to 20 divisions, a total of 25,000 artillery pieces, of which more than 100 mm accounted for a quarter, that is, more than 6,000 guns, in between. There are also 300 heavy 155 howitzers, which were brought specifically for Chita.

In the past few years, the fastest growing military industry in the northwest has been the military industry, starting from the beginning of gun manufacturing, step by step, with the foundation of the Westernization movement, to build the military industry in the northwest. Not only in light weapons, it is unique, whether it is AK11 or squad light machine guns. Heavy machine guns and stunter guns, both out of their own systems, are currently the best light firearms in the world. On top of the artillery. The Northwest is not underestimated either, artillery is the king of infantry. The infantry, without artillery, is simply a target for the opponent.

The Northwest has a natural advantage in the development of artillery. The reason is very simple, all-in-one machine, the biggest benefit of the all-in-one machine is purification and copying, after Yang Yuanzhao summed up the new function, and developed in addition to the synthesis of new materials, 1000 kinds of materials per day, 5 years, is 2 million kinds, under the function of the all-in-one machine, all the effects of these materials are displayed in front of Yang Yuanzhao.

A new material, in order to test its full efficacy, in addition to taking time, also needs some coincidences, many materials to the 21st century, have not found out all its efficacy and the most suitable use, this does not exist for all-in-one computers. The sea of materials may be boundless, with such an exhaustive method, exhaustively enumerating materials, unless it is shit luck, to be able to meet one or two, for the all-in-one machine, it is not a problem.

However, from the very beginning, Yang Yuanzhao made the most efficient use of the effect of the all-in-one machine, he first led himself, with the help of some engineers and researchers, to understand the role of a system of materials, and find out the deep-seated reasons as much as possible.

I have to say that the anti-natural effect of the all-in-one machine has solved the biggest problem of materials science, and the development of materials in the northwest is much higher than the level of science and technology.

In the 21st century, the birth of a new material requires countless tests, each test, the biggest waste is the material itself, some expensive additives, precious metals, processing methods, filled into the material, and then produce a cylinder of material, used to compare his performance, more than nine out of nine, is a failure, but an occasional success, is enough to make the project support.

The cost of the northwest is much smaller, with the help of the all-in-one machine, you can list all the functions of the material, when the number of materials is large enough, you can analyze the deep connection of materials according to the interrelationship between materials, the system, the northwest is with the help of this, the study of at least 12 different materials of the system, through the allocation of the number of additives, adding steps, and finally completed the progress of several systems of materials science.

From the development of world history, to be precise, is the development of tools, directly determines the ability and productivity of man to transform nature, from the ancient Paleolithic Age, people can only transform nature through simple trees, stones, at this time, people themselves are fragile, easy to be transformed by nature, but with the development of tools, the Neolithic Age, the Bronze Age, the Iron Age, into the era of the Industrial Revolution, although it is still iron, but this iron tool is much higher than the iron of the Iron Age, I don't know how much higher, from pig iron, wrought iron, to synthetic steel, in terms of steel, from 1840 to the present, I don't know how much it has improved, especially in the era of battleships, the current steel, and 10 years ago, 20 years ago, there is a stage of progress, which is completely incomparable.

Northwest not only in the engine of the project, the whole world, in the material is even more so, you can say that the material is a foundation, is a systematic thing, the enhancement of materials, many ideas of ideas, or something else, can be realized, this is the benefit of the foundation, the improvement of the foundation is not overnight, but once the foundation is improved, the progress in other aspects is very great, this thing, not you imitate or cottage can learn to go.

Artillery promotion, so that scientists have a lot of choices, Yang Yuanzhao knows that the infantry artillery fire of later generations, most of them are about 150 mm, such artillery, powerful enough, long range, along with the strength, easy to carry infantry, although in the armored research institute, there is a research on self-propelled artillery, but self-propelled artillery is a heavy howitzer, compared with the previous heavy tank 120 mm smoothbore gun, it is not a concept at all, and it is extremely difficult to achieve.

This batch of 155 guns is a new product at the end of 1914, on the basis of the original 155 guns, simply realized the function of self-tightening of part of the tube body, the key parts have been effectively strengthened, the explosion force that can be withstood is further enhanced, quantitatively calculated, compared with the original barrel, the bearing capacity increased by 50%.

The barrel of the artillery can be increased by 10%, which can bring a huge improvement in performance, not to mention 50%, to put it bluntly, artillery is a method of gunpowder to push the projectile, move quickly, and produce lethality, from the simple gunpowder weapons in ancient times to the current guns, the basic concept is the same.

Under the premise of not studying the concept of aerodynamics, increasing gunpowder and increasing the power of gunpowder is the best way to increase the power, the barrel of the 155 gun, after using new materials and the technology of self-tightening of the barrel body, can withstand the chamber pressure at least 2.3 times more than the world's mainstream large-caliber 150 mm artillery, so the power of the artillery is extremely great, and it is much more powerful than the 203 artillery used at that time in 1911, when the battle of the city was sold.

The firing range is also much farther, the maximum firing range can already reach 17 kilometers, of course, this time, the maximum firing range was not chosen, the 155 artillery is relatively evenly distributed between 11 kilometers and 15 kilometers, this distance, has exceeded the maximum firing range of the current Chita defensive artillery.

After the reconnaissance of the aircraft and all other means, Yan Xishan here, there is Chita, the overall layout of the drawings, Chita's biggest reliance, is his defensive artillery, the number is quite a lot, reaching 300, but more than 120 mm, only 87, the reason is very simple, easy to carry, the relatively new more than 100 mm artillery, all taken away by Brusinov, left behind, are old-fashioned, inconvenient to carry.

The largest caliber is 254 mm, which is more than 30 years ago, the main gun of a capital ship in Russia, after the rear was eliminated, this front-loading gun was gotten to Chita, a total of 6, on the top of the battery, the caliber is not small, but it cannot be rotated, and even the amplitude of moving up and down is not large.

254 mm artillery, let alone unprotected infantry, even if it is a tank unit, do not dare to be careless, even if it is a heavy tank, under the premise that a gun of such a caliber, hits the frontal armor on the premise, it is also the result of one shot.

Of course, it is precisely because of this that such a heavy artillery can only rely on the battery to move, this battery, basically, is still a retrofit of the battery of an old-fashioned battleship, on land, and different from on the ship, you can adjust the direction according to the movement, adjust the direction, to adjust his trajectory and the direction of alignment, basically there are not many dead ends, but on land, no matter how much you pay attention, there are still dead ends, and the range of dead ends is quite large.

When Yan Xishan arranged the army, he took into account the angle of the 254 artillery, and in that angle, he did not arrange troops as much as possible, or simply arranged some observation posts and scouts, etc., and used 254 mm artillery to strike at the dense army, which was quite powerful, but when it was aimed at a person alone, it was an anti-aircraft gun that was useless to fight mosquitoes.
