Dong Ku was lacking in skills at this time, and could only be tired of defense in the face of the continuous attack of Soviet Russia, and stationed 200,000 troops at a distance of more than 100 kilometers to deal with the attack of Soviet Russia. There were no more Russian air raids, and in the middle of May, when there was only snow in the back of the mountains, the Russian air raids never came again.

It's not that the Russians really gave up, but that Dong Ku once again smashed their air raids, so that the Russians were powerless to resist the anti-aircraft artillery of the advance army and died down, and no longer wasted expensive planes as fireworks.

Soviet Russia thought that it would use the people lurking in the territory to make internal responses, set fire to guide the bombing targets, and carry out a large-scale night bombardment, but it did not expect that the lurkers were captured by the advance army when they were plotting to step on the point, and they followed the vine to capture all the lurking personnel, and learned of the Soviet Russian air raid plan.

Dong Ku, of course, did not miss this opportunity, and in the hours before the air strike, he sent a telegram to Siberia confirming that the air attack could be carried out. And he, in the wilderness, prepared several locations, the town curfew strictly prohibited lights, and anti-aircraft guns were arranged around these points.

When the Russian bombers flew near the sky, they just saw the fire on the ground, and then the pillars of light locked on them, and before the Soviet Russian bombers who knew that the road was not good reacted and left, the barrage covered the airspace.

Under the positioning of the listening machine and the guidance of the searchlight, a total of 360 planes of the Yi series were left in Mongolia, and there was no need to worry about the problem of insufficient fuel on the return trip.

This blow also made the bearded man completely dead, and before he could solve the opponent's anti-aircraft artillery, he decided to use the tactics of crowds to continue to drag down the advance army.

Of course, his trick was still very effective, and the large troops of the advance army were stunned and could not leave this defense area, even if there was no battle. can only stay on the top of the mountain, in the dense forest, and cannot leave. As a result, a lot of supplies and ammunition are consumed.

Fortunately, the ammunition is still quite sufficient here in Dong Ku, and even if it is constantly consumed, it does not make his logistics tight. It's just that it is impossible to let the army leave, and it is difficult to have the opportunity to implement other strategic goals, which makes Dong Ku distressed. If he expanded the recruitment, he could not afford to raise it, and there was not enough food, so he still ordered the purchase of a large number of cattle and sheep in the hands of the Mongols to be slaughtered, or made into jerky, or sent directly to the house. to fill the food gap.

As for the large-scale slaughter of cattle and sheep, in fact, Dong Ku is not entirely because of the lack of grain, but he has the memory of later generations, the desert of the grassland, and the excessive development of the four wildernesses is one thing, the key is the number of cattle and sheep surged, the pursuit of production at the same time, can not take into account the rotation of the grassland. As a result, desertification is difficult to control once it occurs. Even if the Mongolians cherish the pasture, after all, the animal is not something that people can control, so they control the number of cattle and sheep in advance, gradually abolish nomadism, and graze at fixed points. Or captive breeding, reducing the destruction of grasslands, and also making some contributions to leaving some beautiful grasslands in the future.

Just when Dong Ku was not fixed here and there was a fierce battle in the patch region, a piece of news made him really excited.

Crescent Island there. Shanzi sent a telegram and reported to Dong Ku that in the past few months, except for the end of the plucking plan, the convergence of all the more than 600 scientists on the list, and the more than 600 scientists brought in by the way, the research work has been carried out in an orderly manner, and whether they want to or not, these scientists have devoted themselves to research in their respective fields. With their participation, some of the previous projects of Jewish research, due to the lack of scientists in some fields, led to many projects not perfect, or even unable to carry out normally, after these scientists are in place, many projects have been gradually launched.

And these scientists, as Dong Ku expected, saw the scientific and technological directions that they imagined or did not expect for the time being in their own fields, and they all frantically invested in research, and solved a lot of problems for those projects that had directions before, but no one came to solve them, and as a result, one project after another was launched, and new scientific and technological products continued to appear.

Shanzi's message listed several products that had been finalized these days, and a few products that had solved most of the problems and were just short of being produced.

Here, what makes Dong Ku the happiest is the research of engines, which include not only airplanes, tanks, trucks, etc. These engines were all products of the mid-to-late stages of World War II, so to speak, a few years ahead of schedule. With these engines, Dong Ku's favorite aircraft tank can be successfully manufactured into the model he needs.

In addition to the engine, there are also modified U-submarines that have been manufactured and launched for a long time. The U-boat was quite good at the end of World War II, but the diving was only a limit of 600 meters, and 700 meters was a miracle. The submarine structure given by Dong Kuci is a better U-boat that Germany did not have time to produce at the end of World War II, and it is a top-notch product in the early days of the Cold War.

The structure and other related things have been solved and produced by Jewish scientists on Crescent Island, the only thing that cannot be solved is the engine, and the blades of the propeller, the way to reduce the noise, so that the submarine that already has a body has been docked in the dock for several months.

Just a few hours earlier, the sonar detection and diving depth experiments had ended, and the unnamed submarine had surfaced in the deep waters on the side of Crescent Island, amidst cheers. After inspection, the whole boat was not damaged, and the submarine was also dived at a depth of 750 meters, staying for two hours, and if you do the limit dive, the depth of 800 meters can be reached.

There is another one, that is, the torpedo, the torpedo has also successfully achieved the level of the middle and late stages of World War II, although it does not reach the speed given by Dong Ku in the early days of the Cold War, but now, when the torpedo trajectory is discovered, it will be too late to dodge.

In addition to the fact that the submarine already has combat capability, and some auxiliary parameters can be finalized and mass-produced, there are also landing ships, hovercraft, and small walkie-talkies that Dong Ku needs.

The landing ship was relatively simple, and it was only because the power of the engine, the displacement of the propeller, and the torque of the propeller required by Dong Ku could not be solved, and the hull and other ancillary parts were also produced, but it could not be launched. After the engine was solved, the alloy technology of the steel was improved, all the problems were solved, and the test was completed today.

As for the air-cushion landing ship, it was also launched yesterday and all the tests were completed today.

Here, what makes Dong Ku the happiest is the walkie-talkie. With the efforts of scientists, walkie-talkies have been able to cover a range of five kilometers, and independent channels, multiple walkie-talkies at the same time, as long as the small volume of the headset required by Dong Ku is solved, and the power is increased, the coverage is a little wider, it can be produced.

With walkie-talkies, which were only solved during the Cold War, Dong Ku believed that his special forces would be invincible to any country and would be invincible.

In addition, Dong Ku also has several special forces auxiliary items that he needs, and when the electronic problems are solved, he can be trial-produced.

And one of the most important things is rocket artillery.

After those scientists were in place on the island, several scientists in related fields were gathered, and after two months of research to solve the problem of parameters given by Dong Ku, finally, the first rocket successfully flew out of the barrel.

This shoulder-fired rocket developed according to the 604 rocket launcher will solve the drawback of the iron fist aiming too closely, and with the current amount of auxiliary propulsion, it can hit the target and destroy it at a distance of 300 meters. After solving the most difficult problem of boosting gunpowder, this rocket will be able to reach a range of 600 meters.

There is one more thing that Dong Ku is looking forward to, and that is the helicopter.

The helicopter was not conceived by no one at the beginning, but it was impossible to solve the centrifugal force and torque balance generated when the propeller rotated, and Dong Ku was given the direct parameters, and scientists only needed to solve the materials and engines that the current production technology could not reach, and these, after the series of engines were made, the helicopter was no longer a problem.

The reason why Dong Ku researched helicopters was actually because before there was no over-the-horizon lock-on strike capability, aerial dogfights, fighter jets were not as good as flexible helicopters, after all, the flight speed of fighter jets in this period was too slow, not faster than helicopters, or even inferior.

These will be put into production in a few months, and the island is building a related production plant, and it is believed that in three or four months, the first gunship will be available. As for the study of attack aircraft and bombers, Dong Ku did not relax either. When Dong Ku's helicopter shines on the battlefield and other countries devote themselves to research, they will lag behind fighter jets that are faster and sharper in attack, and suitable for big wars. And in the future, helicopters without missiles will be eliminated, become pig's feet in local wars, and withdraw from the stage of big wars. By that time, when they went back to the study of fighters, they were already lagging behind.

During this time, Dong Ku already believed that he could lead or change the trajectory of part of history, but his Dafang idea would not change, so he wanted to squeeze out time for backward China, so that China would have enough time to catch up with the development speed of the great powers and improve the overall industrial revolution after driving out the invaders.

The release of these weapons, Dong Ku was pleasantly surprised, and the depression of being forced by Lao Maozi to carry out a war of attrition was swept away, he had already seen him for another two or three months, his tank came out, and the helicopter came out, what kind of surprise would it give Lao Maozi and Japan, he would achieve his goal, drive Lao Maozi out of Asia, cripple little Japan, perhaps, it is not difficult to establish a Tokyo Province.

It's just that Dong Ku didn't know what to do at this time, and he didn't have a chance to complete his plan in a short time, because history has changed, even if the wheel doesn't stop, the variables have come out, and it will be a change that he can't predict and control......
