300 155 heavy howitzers, with their characteristic armor-piercing shells, passed through more than ten kilometers of distances between them and accurately hit Chita City. At the same time, tens of thousands of cannons with more than 100 mm fired at the same time, and tens of thousands of cannons were fired at the same time. Just a base cannon, the Chita was flying dust.

In Chita City, the Russian army was baptized by artillery. Countless artillery fire exploded and roared in the city. Fortunately, all the houses made of stones were strong enough, and there were old castles. These soldiers hid in the house, and only a few of them were unlucky, and they were hit by shells or bombarded by shells.

The artillery fire in the northwest has always focused on timeliness, and high-explosive armor-piercing bombs are amazingly efficient in exercises, but they are still not strong enough in the face of a defensive worker like Chita who is all made of stones. The effect produced by a round of broken artillery fire is almost minimal.

After a round of artillery fire was prepared, the artillery gradually stopped. All the Northwest Army officers who looked at the telescopes, looked bad in their faces. A base cannon was at least hundreds of thousands of shells. Logically speaking, the Red Tower should be in ruins, but when they looked over, most of the houses were intact, and to some extent, they were a little better than the reinforced concrete ones.

I knew that Chita's defense was all-round, but it was beyond everyone's expectations that the defense was so powerful that it was beyond everyone's expectations. Yan Xishan had prepared for it, but Chita's defense still made him feel a little tricky. He cut off the Siberian Railway, and with all other necessary preparations, he had at least 20 days to capture Chita. This was only one artillery preparation, and under his attack, it should have an effect, but the actual effect was not satisfactory. It took a long time to capture such a strong city.

The initial contact between the Northwest and Russia came to an end. On the front line of Chita, the Northwest had an absolute advantage. Whether in terms of firepower or preparation, the actual effect was minimal. If you don’t think of other solutions, you might be prepared. All this preparation is illusory.

Baotou, northwest, is another busy day. It is a big city with a population of over 10 million, and the new capital of China. Baotou has gradually accepted this status quo. The entire city and even the entire country have developed smoothly, and the battle in the north has not affected many other mentalities, but at most it is the attention of military enthusiasts.

The Northwest started with wars. It began with a number of wars since its rise in 1908. There was no defeat. It was this series of victories that gave them enough confidence to make them believe that China would not suffer failure.

In Yang Yuanzhao's office, the battle reports on the front line flew like snowflakes. He was always hesitating whether to use the aircraft. Although the Northwest has been using aircraft one after another, and other countries, like history, while developing airships, they also discovered the role of aircraft. Some aircraft began to enter the army of various countries to conduct reconnaissance, and the military role of aircraft began to appear, but these aircraft were at least 20 years away from the Northwest aircraft. In a short period of time, before huge progress was made in the materials, the Northwest was not worried that the other party's aircraft would catch up with it. In this case, even if the aircraft was exposed, the impact on the Northwest would be minimal.

But is it okay to have the plane? According to the actual situation sent back by Yan Xishan on the front line, Chita's protection ability is much stronger than they expected. All are cities built of stones. After hundreds of years of operation, cities that have been in operation and have been in the cold for countless years, are really strong. It seems that Russian cities are like this, Chita, Chita, and Chaktu, and even Leningrad during World War II. They are not rigorous in the Russians. They are not rigorous in the Russians. The construction of houses is made of real materials. The key is climate and reality. It makes cities built without stones easily fall down due to cold or north wind. Only stones with real materials can be preserved for hundreds of years.

Strategic bombers carry a little more explosives than ordinary bombers, and armor-piercing bombs falling from high altitudes are also more powerful. But are these enough to bomb a city? During World War II, there were not many big cities that were bombed. An obvious example is London and Japan.

Due to the earthquake, most cities in Japan were mainly brick and wood structures, so they suffered huge losses when bombing. But even so, Japan never surrendered during the bombing. On the eve of bombing Tokyo and many industrial bases, Japan made Kamikaze special attack stronger, and there was no other move except for the strong attack.

Bombing cannot solve a country, even Japan, which is now exhausted from ammunition and food. Due to the emergence of Yang Yuanzhao, the Northwest has paid attention to the role of the air force earlier than other countries, and aviation bombs have also been released in advance. In order to enhance their power, especially when Yang Yuanzhao proposed some ideas known to later generations, aviation bombs are really changing with each passing day, from 25 kilograms to 50 kilograms at the beginning to 1,800 kilograms at the beginning, especially the latter, which is no longer suitable for use on land, and is used against warships, especially warships with more than 50,000 tons.

In the General Staff, it is not that there are no staff members who have studied the problem of bombs, but the final problem all point to a result. Bombs have great lethality for unprotected infantry, but the effect is minimal for urban offensive and defense, especially for prepared urban defense forces.

On the practical training ground in the northwest, the amount of damage to the secret defense and the city of aviation bombs is almost minimal. Of course, in addition to intensive bombing, he has been hesitating about another topic, but in order to increase the power of the air force, he still proposed it, very simply, it is incendiary bomb.

The cracking products of oil have relatively large energy and are far higher in thermal effects than explosives, but they are not that outstanding in explosiveness. With the help of these energy and some methods to improve their explosiveness, they can create weapon-level incendiary bombs.

In the era of knowledge explosion, Yang Yuanzhao still knew that the earliest incendiary bombs were to use a mixture of gasoline and rubber, and add other combustion aids. The second generation was aluminum thermal agent, which used the combustion energy of aluminum and magnesium to increase the explosiveness of gasoline.

Compared with ordinary bombs, incendiary bombs are much crueler. Especially the second-generation aluminum thermal agent, which can be made into cloud explosion bombs at a sufficient dose.

Although this thing is a conventional weapon, it is not much weaker than a restricted weapon. Especially for narrow spaces and tunnels, it is simply a killer weapon. There may not be many direct damages. However, the vacuum effect caused by the extraction of air can directly suffocate everyone to death.

Therefore, cloud explosion bombs are also called nuclear weapons among conventional weapons, entering the new century. The development of technology is almost changing with each passing day. Among conventional weapons, all weapons far exceed the ordinary level in the world have been born. Cloud explosion bombs are one of them. After thinking for a long time, without solving the problem of forecast orders, countries can only produce cloud explosion bombs.

In this era, there is still an unsolvable problem for cloud explosion bombing. The emergence of airships has made bombing the main force in the world's ground attacks. In fact, if you think about it carefully, this weapon has a very wide range of use.

Since he had overcome the hurdle in his heart, Yang Yuanzhao let go a lot and directly expressed the creativity of the two incendiary bombs. He gave it to the Northwest for research, and with clear guidance. The most important thing is that the Northwest controls a rubber and oil production area. These two things are ready-made, and the development of the first generation of incendiary bombs was very smooth.

A month ago, the laboratory was completed and is now being produced in small batches. Currently, 2,000 pieces have been produced, all of which are in the 200 kilogram level.

According to the test calculation, the 200 kg incendiary bomb is much more powerful than the 200 kg bomb under the premise of dense release. Especially for cities with reinforced concrete, when this amount reaches a certain level, only the air in the area is extracted in large quantities, and the suffocation effect of this vacuum effect is enough to solve most problems.

I had been hesitating before whether to use this thing or not. Now, according to Yan Xishan's plan and after careful research by the General Staff, there may be more than 50,000 or even 100,000 casualties, and Yang Yuanzhao could no longer sit still.

From beginning to end, the Northwest paid far more attention to personnel than other countries in the world. Whether during the Qing Dynasty or during the war against Russia, even if the war in the northwest was fierce, the attention to personnel was the world's number one. At this critical critical juncture, perhaps he could not express his position, but the general trend was still irreversible.

Although the production of the incendiary bomb is still in a confidential state, Yang Yuanzhao looked at the red telephone at hand, answered the special forces' phone number, and then issued an order.

Three hours later, a regiment of the Special Forces escorted 2,000 200 kilograms with huge red exclamation marks on it, and boarded the train heading for the sale.

The fire of the Annunciation finally stopped at night. During this day, the northwest fired a total of more than 2 million shells of large and small caliber shells at Chita. Almost every gun fired 100 shells, with saturated and dense attacks, which had some effect on Chita. Some non-stone-built buildings or smaller buildings were hit by devastating blows. Unfortunately, the main body of Chita is still strong, and even the city walls can't see many traces of damage.

In the military command, Yan Xishan frowned and had been prepared for the protection of Chita for a long time, but Chita's protection was still beyond his expectations. It was too powerful. In this way, let alone three to five days of artillery fire preparation, even 10 days and half a month of artillery fire may not be able to blow the strong protection of Chita. How to fight

"Or why, let the troops have a feint attack tomorrow to test it." A staff officer said tentatively.

Feint attack, yes, according to the plan, under the premise that the artillery preparation is not effective, you can choose to let the troops' feint attack, find out the opponent's weakness through close contact and consume the opponent's army. Unless the artillery is in a field environment and in urban warfare, it is a red undead person, and the army must be tried.

Unfortunately, the opponent's defense line has not been broken yet, and even the personnel losses are not large. There is enough room for attack. As long as a large number of personnel are sent, the number of casualties will rise.

Whether to try it or continue to prepare for artillery fire, it takes time to solve it. After hesitating for a long time, there was no way. In the end, Yan Xishan chose to wait. Anyway, the logistics supplies were sufficient, and the temporary walkway was built with various road construction machinery. The progress was smooth. It was less than 40 kilometers away from Chita. It could be completed simply in one week at most. At that time, logistics would no longer be a problem.

The Northwest is large-scale production, produced using large-scale machinery and automated production lines. When the quantity reaches a certain level, the cost of various weapons is actually extremely low. In terms of production efficiency, the Northwest's production efficiency is 5 times that of the United States and about 7 times that of Germany and the United Kingdom. Under the premise of such production efficiency, many additional costs are being reduced. At most, the cost of weapons is about twice the cost of raw materials. Especially under the premise of super-large-scale procurement, it is still slowly reducing, and the limit may be reduced to 70% or 80%, which is already a very low value.

Take the current situation as an example. It seems that the price of shells that are one million a day can be purchased is only equivalent to the purchase price of the Russian army of about 200,000, of which 50,000 are the difference. The reason is very simple. The American rental bill seems that the United States has paid a lot, but the United States pays the government, and arms dealers have to make money. The arms dealers have added enough profits, which may be one or two times. On this basis, the government has increased a little and reduced government spending.

If there were no more artillery fire preparations for two days, Yan Xishan sat down on the decision that made him very grateful, because within two days, the order from the Northwest General Staff had already been called, suspending the attack and waiting for the headquarters special forces to come.

Although Yan Xishan didn't know what the special forces could do when they arrived, he still waited because the surrounding situation was very good, and the structure of the two armies' blocking positions was quite sorted out, especially after the pavement was repaired, various machinery passed the railway from Buying and Selling City to Kulun

It was sent to the front line continuously, with high-grade special cement, and various concretes quickly, and various solid fortifications began to be constructed. If the front could withstand artillery below 100 mm, it could now almost withstand artillery below 180 mm. With the two wings being more solid, the time to attack the Chita was more guaranteed. Not to mention 2 days, even three or five days, it would be enough to wait.

While waiting patiently, two days passed in a flash. In the past two days, Yan Xishan was patiently waiting for the result of the artillery fire. The Red Tower, which is all made of stone, has strong protection. Although there is not much attack, it has more than enough defense. Three days have passed, and countless shells fell under the Red Tower's city wall. However, the Red Tower is still under the protection of the Russians (to be continued.)
