He was nervously studying and thinking about ways all night, but after dawn, Oluyumov shook his sleepy body and was about to take a nap, but the adjutant ran in panic and shouted: "Not good, no good!"

"What a panic? Is the Zhongzhao team going to attack the city?"

The adjutant nodded and Oluyumov said disdainfully: "Isn't it just siege the city and let them defend well, don't lose the chain like last night!"

After saying that, the adjutant who thought he was going to go out did not go out, so he was holding back and didn't know what to do. Finally, the adjutant said: "Master Commander, you should go out for a while!"

"Go out!" Shaking his head helplessly, Oluyumov still went out. On the observation post of the fortress, he saw what the adjutant said was heroic. Around the Chita, within a range of 10 kilometers, the Zhong** team set up a defensive camp, without any intention of siege. However, after a closer look, the opponent's artillery troops were ready. However, on the east side, there were thousands of artillery seen. The number of artillery around the entire Chita can be imagined.

Artillery is the king of infantry. Any infantry has fewer artillery and its combat effectiveness has at least decreased a lot. However, such a huge artillery force is placed in front of the Russian army. All the Russian troops who see all this are swaying. They don’t know what to do. Although Chita is a strong city and a fortified city, there are too many artillery on the other side, and tens of thousands of artillery cannons. If they are bombarded day and night, how long can the Chita last?

The first time, Oluyumov did not scold the adjutant, and he was speechless. Isn’t it just a fortress? Why did the Chinese move such a big formation?

The Chinese team got up early today. After the artillery arranged the artillery, they began to prepare for the first round of artillery fire.

In addition to guarding a small number of Mongolian troops, the remaining troops gathered in Chita. Putting aside the two armies in charge of blocking possible reinforcements, a small Chita gathered 400,000 troops, nearly 20 divisions, and a total of 25,000 artillery pieces were used, of which more than 100 mm accounted for one quarter, that is, more than 6,000. Among them, there are 300 heavy 155 howitzers specially brought for Chita.

In the past few years, the fastest development of the Northwest was the military industry. Starting from the start of building guns, we gradually built the military industry in the Northwest with the foundation of the Westernization Movement. Not only was it unique in light weapons, whether it was AK11 or squad light machine guns, heavy machine guns and blocking guns, they all came out of their own system, and are currently the best light guns in the world. Above artillery, the Northwest, has not underestimated it. Cannons are the king of infantry. Infantry is simply the target of the opponent without artillery.

Northwest has natural advantages in the development of artillery. The reason is very simple. The biggest advantage of all-in-one machine is purification and replication. After Yang Yuanzhao summarized the new functions, he developed 1,000 materials per day, and 2 million types in 5 years. Under the functions of the all-in-one machine, the full effect of these materials is displayed in front of Yang Yuanzhao.

It takes time to test the full effect of a new piece of material, in addition to time, it also takes some coincidences. Many materials have not found out their full effect and most suitable use in the 21st century. This does not exist for all-in-one machines. The sea of ​​materials may be boundless. Using such an exhaustive method to exhaust the materials, unless you have luck in getting one or two, it is not a problem for all-in-one machines.

However, from the very beginning, Yang Yuanzhao used the functions of the all-in-one machine to the maximum efficiency. He first led himself. With the help of some engineers and researchers, he used the materials of a system to understand their role and find out the deeper reasons as much as possible.

It has to be said that the aura of the all-in-one machine has allowed the biggest problem of materials science to be solved easily. The development of materials in the northwest is much higher than that of technology.

In the 21st century, the birth of a new material requires countless tests. The biggest waste of each test is the material itself, some expensive additives, precious metals, and processing methods, filled into the material, and then a cylinder of materials is produced to compare its performance. More than 99% of them are failures, but an occasional success is enough to support this project.

The cost of the Northwest is much smaller. With the help of an all-in-one machine, you can list the functions of the materials. When the amount of materials is sufficient, you can analyze the deep connections of materials based on the relationships and systems between materials. With this, the Northwest has studied different materials of at least 12 systems. By combining the quantity of certain additives and adding steps, the progress of several systems of materials science was finally completed.

From the development of world history, to be precise, the development of tools directly determines the ability and productivity of human beings to transform nature. From the Paleolithic Age in ancient times, people could only transform nature through simple trees and stones. At this time, human beings themselves were fragile and could easily be transformed by nature. However, with the development of tools, the Neolithic Age, the Bronze Age, and the Iron Age, entering the industrial revolution era, although it was still iron, this iron tool was much higher than that of the Iron Age. From pig iron, cooked iron, to synthetic steel, among steel, from 1840 to the present, I don’t know how much it has improved, especially in the battleship era, the current steel has made progress 10 years ago and 20 years ago, which is completely incomparable.

The Northwest not only has the engine project, but also in materials. It is also true that materials are a foundation, a systematic thing. The enhancement of materials, many concepts, or other things can be realized accordingly. This is the benefit of the foundation. The improvement of the foundation is not overnight, but once the foundation is improved, other aspects are made great progress. This thing is not something you can learn by imitating or copying it.

The improvement of artillery gives scientists a lot of choices. Yang Yuanzhao knows that most of the infantry artillery fire in later generations were about 150 mm. Such artillery has sufficient power and long range. It is powerful and powerful, making it convenient for infantry to carry. Although there is research on self-propelled artillery in the Armor Research Institute, self-propelled artillery is a heavy howitzer. Compared with the previous heavy tank 120 mm smoothbore cannon, it is not a concept at all, and it is extremely difficult to implement.

This batch of 155 artillery was a new product at the end of 1914. Based on the original 155 artillery, the function of some self-tightening of the tube was simply realized. The key parts were effectively strengthened, and the explosive force it could withstand was further enhanced. Quantitatively, the bearing capacity increased by 50% compared to the original artillery barrel.

The cannon barrel can increase by 10%, which can bring about a huge improvement in performance, not to mention 50%. To put it bluntly, the cannon is a way for gunpowder to push the projectiles, move quickly, and generate lethality. From simple gunpowder weapons in ancient times to the current guns and cannons, the basic concepts are the same.

Without researching the concept of aerodynamics, adding gunpowder and increasing the power of gunpowder is the best way to improve power. After using new materials and self-tightening technology of the barrel of the 155 artillery, the chamber pressure can be withstand at least 2.3 times higher than the mainstream large-caliber artillery above 150 mm in the world. Therefore, the power of the artillery is extremely powerful, which is much greater than that of the 203 artillery used in 1911.

The range is much longer, and the maximum range can reach 17 kilometers. Of course, this time, no maximum range is selected. The 155 artillery is more averagely distributed between 11 kilometers and 15 kilometers. This distance has exceeded the maximum range of the current Chita defensive artillery.

After the aircraft's reconnaissance and all other means, Yan Xishan has the Chita and the overall layout drawings. The biggest reliance on Chita is its defensive artillery, with a large number of 300, but there are only 87 of them above 120 mm. The reason is very simple, and the more portable cannons that are more than 100 mm were taken away by Brusinov. The ones that are left behind are old-fashioned and inconvenient to carry.

The largest caliber is 254 mm. This is the main gun of a Russian main battleship more than 30 years ago. After being eliminated from the back, the front-loading gun was pulled into Chita. There are 6 pieces in total. On the top of the turret, the caliber is not small, but it cannot be rotated, and even the up and down movement is not large.

The 254mm cannon, not to mention the unprotected infantry, even tank troops dare not be careless. Even heavy tanks are shot at the front of the front armor by such a caliber artillery.

Of course, it is precisely because of this that such a heavy artillery can only rely on the turret to move. This turret is basically a modified turret of an old warship. On land, unlike on ships, it can adjust its trajectory and alignment direction according to movement and orientation. There are basically no blind spots, but on land, no matter how much you pay attention, there are still dead spots, and the range of dead spots is quite large.

When Yan Xishan arranged the army, he considered the angle of the 254 artillery. In that angle, he should not arrange troops as much as possible, or simply arrange some observation posts and scouts. If he uses 254mm artillery to target dense troops, it will be quite powerful, but when targeting a person alone, it is a proof-aircraft gun to kill mosquitoes and is useless. (To be continued.)
