The republican army conquered the Changchun area of Jilin Province, and the results of annihilating and capturing Haisong 56312 during the retreat of Hai Song were announced, which was already the fourth group army that Hai Song lost in the hands of Ren Di. With the losses of guerrilla warfare, it is conservatively estimated that the permanent combat attrition of Hai Song reached 180,000, and such a defeat is a great defeat in front of any country. But there is only one country in the world that can (dumb tape).

However, in the face of this failure, the leadership and decision-making level of the normal country, after thinking about the pros and cons of the occupation, began to consider giving up this war that cost more than the budget, but the leaders of Hai Song had the same deep vision as Jiang Gong, and it was obvious that their competitors in the next fifty years were here. did not change generals on the spot, and arrogantly left hundreds of thousands of troops to a veteran as a tuition fee for battlefield training.

When the snow cleared, a rocket swooped down from the clear blue sky and hit the thick walls of Shenyang, breaking only a few bricks covered with ice, which meant that the Republican offensive against Haisong could only end here. Because there is no heavy artillery, it is no longer practical to rely on rockets alone to fight a fortified position. The city of Shenyang is the base camp built by Wu Jiajun to guard the northeast, and it is not an exaggeration to say that this city is a fortress-type city.

Rocket artillery, light mortars, a dozen infantry, and the collapse of a bunker house are almost the same, and it is really necessary to deal with this kind of reinforced concrete structure with a wall thickness of one or two meters. It was necessary to attack the fortifications with heavy artillery, or bombardment with aerial bombs with large carriers. However, this is still a problem in the final analysis, and the Republic is now unable to build power machinery that can set large war machines in motion. In the face of such a hard city wall and a series of defensive structures, Ren Di can only say that Lao Tzu wants gas turbines to pull trucks, tanks, and fighter planes.

As for the blasting of the civil engineering tunnel, now the northeast permafrost layer has been dug with a few shovels, and it cannot be dug at all. As for the tank, Ren Di tried to make it, whether it was a piston or a gas turbine engine, he tried to cast it, but this thing is fragile when it is stuffed into a combat vehicle made of steel shells to form a whole.

Rocks are harder than our skin, and we can't crush a random stone from the ground (say the dead side of sandstone), but a stone flake one millimeter thinner, we can easily use our thumb and forefinger to pinch this small stone flake into powder, it is not that the skin on our fingers is harder than the rock, the chopped rock, but the force on our fingers that the rock flakes cannot bear. The same is true for steel, if it is a whole piece of iron rod with a diameter of one decimeter, it can naturally withstand a lot of impact force, but the countless small steel parts of the engine bear the force of fuel explosion, and the output force is several tons of steel machinery, and the force that pushes such a large machine is equivalent to the engine that outputs energy, just like our fingers pinch a stone chip hard.

Ren Di's experiment in the production of combat vehicles was very unsuccessful, with various engine parts broken and teeth on the transmission gear collapsing. If such a tank goes to war, forget it, this crime is still not guilty.

Of course, there is another problem with large-scale mechanization, and that is oil. On oil, about 150 kilometers northwest of Harbin, the famous Daqing is here. The location of the Daqing oil well was precisely in the rear of the Republican Army. The current technology is just right for mining. Well, but it's just enough to mine.

The Northeast of this era is still too desolate, how to say, Vladivostok is still a small fishing village. Hai Song has a series of natural ice-free ports such as Sasebo and Busan, and has no interest in opening up port cities on the coast of the ice fields north of Heilongjiang, as for Daming, Dalian Lushun and other ports in hand, after the threat of the Jurchen savages in the northeast is eliminated, it is equal to a natural invincible state in the northeast. There is no economic benefit from the opening of the port of Vladivostok.

The same is true of the port, the same is true of the railway, the railway in the northeast is all concentrated in the area of Shenyang around the Bohai Sea, as for Harbin Yichun Heilongjiang River basin can not see traces of industry. Even the railway in Changchun only stayed on the desk of the elder of the Ming Dynasty in the middle of 1700 and did not become a reality. Of the 40 million people in Northeast China, about 25 million live in Liaoning, which is located around the Bohai Sea. Liaoning is also an important base for Wujia's coal and iron industry. Anshan and Fushun are two places, one iron and one coal, just got him together. Of course, this piece of coal and iron is finally a factory that Haisong provides technology and skilled workers, as well as core components. The industrial output value of the entire Northeast Shenyang region covers more than 50 percent of the entire Northeast China. As for the north, except for the coal mining in Xiaoxinganling, Heilongjiang, there is no industry.

Occupying Liaoning, with the support of steel bases and military factories, as well as a well-developed road network, the lack of heavy weapons of the Republican Army from the north is basically difficult to fight. If you want to play, you can only start from the corners and corners.

Ren Di calculated his strength, well, forget it, let's talk about it after the railway line is repaired. As for now, Ren Di is building his own coal and iron base. The large tract of land that Ren Di now controls is not useless, and the grain production data of the 21 st century has such data, and Liaoning's grain output is about 35 billion catties. Jilin's data in 2011 was 65 billion catties, and Heilongjiang Province's grain output was about 85 billion catties. Of course, this level of grain production is not expected to be attainable now, but we can see the potential of this door-shaped land on the Northeast Asian continent, including the Great Khing'an Mountains in the west, the Small Khing'an Mountains in the east, and the Great Khing'an Mountains in the north. The potential of this land was not developed by the Ming Empire. Haisong could only rely on the port to temporarily infiltrate Liaoning.

The wartime system was not only for war, but also for economic construction, and millions of laborers were engaged in industrial and agricultural production, grain cultivation, and coal mining in a vast area. The entire Northeast Workers' and Peasants' Government runs like a machine. At present, the north side of the Northeast is not bounded by the Heilongjiang River, and the specific geographical location should be bounded by the Outer Xing'an Mountains. As for Maozi, he is still fighting with Turkey, and he doesn't dare to come to the east to find fault, and the troops who are looking for fault are all cleaned up by Yunchen and Yili.

There is no iron ore on the south bank of the Heilongjiang River, but on the north bank of the lower reaches of the Heilongjiang River, there is a small place in the Jewish Autonomous Prefecture on the mouth of the big rooster on the Rendi plane China map, which contains iron ore reserves of one billion tons, which corresponds to the coal mine on the small Xing'an Mountains on the south bank of the Heilongjiang River. That's why a steel mill was set up in Yichun in the middle of it.

Grain, coal, iron, plus the population migrating north. This is Ren Di's current strategy, and under this strategy, Ren Di doesn't want to fight Nogi Noshinori's kind of meat #Dankejian City tactics. If the army consumes too much, it will inevitably be replenished from the production population, and in the future, there will be steel and heavy artillery, large areas of land to be developed, and a large number of machinery can be formed at a speed under Ren Di's talent. At the same time, there is also the support of the whole of China, and this support can enter the northeast as long as the 200,000 troops are opened on the collection line.

When the battle line was re-compressed to the border between Jilin and Liaoning after the conquest of Changchun, the two sides again reached a stalemate, although territorially the Republican army overwhelmed the expeditionary force of Hai Song in the northeast corner.

Zhao Weiguo has now moved the provisional government to Zhengzhou. The Northeast Campaign had already involved the development of the whole country to some extent, and when Changchun was subdued, the republican provisional government was in a state of excitement, and Zhao Weiguo sent a telegram to the northeast: "Is it possible to achieve a decisive victory in the war in the near future?" Ren Di said very clearly: "Now we can only do this, and we will fight in specific big cities, and we will wait for the country's industrial strength to keep up." ”

The fact that the Northeast Campaign did not end in one day shows that the Bohai Bay is not safe, and the strategic location of the capital of Beiping is not safe. Zhao Weiguo's telegram seemed to remind Ren Di, and Ren Di immediately sent back dozens of telegrams, asking for mechanical parts, skilled workers, doctors, agricultural technicians, and mineral technicians. Zhao Weiguo couldn't cry or laugh when he saw this large pile of telegrams with various urgent tones like snowflakes, and it was obvious that he was beginning to gain the upper hand, as if he was going to perish tomorrow.

But thinking about the strategic location of the Northeast, Zhao Weiguo gritted his teeth and gave Ren Di everything he wanted, and in January and March 1706, the Republic supported 150,000 talents of various types to the Northeast. As well as objective mining machinery, in order to supervise the progress of the Jitong line, Zhao Weiguo also couldn't sit still in Jiujiang, and directly set the provisional government in Zhengzhou, and then supervised the construction of the Jitong line every once in a while.

The contest between the nascent republic and the Hai Song was already to the point of a general war. And now in the second half of winter, the front in the northeast has strangely calmed down. The regional war in the Liaoshen area suddenly calmed down. Ren Di's hot and cold war decree was shocking to all observers at the time. For a time, Hai Song, South Asia, Northeast Asian islands, and major European newspapers began to speculate about what Ren Di's combat style was like. Since Ren Di's debut, there have been a series of battles, ranging from slippery sports battles to thunderous annihilation battles. and the wildness that had just annihilated the two group armies of Hai and Song in a fierce posture on the land of Northeast China. It seems that Ren Di's specific combat style cannot be seen. This kind of changeable, battlefield magician, the outside world began to give Ren Di this title.

But in fact, decades later, because a large number of people began to write memoirs about Ren Di, they understood exactly the reason, since Ren Di's debut, the army command and staff team has been changing, and most of this team was not born in a professional class, and the style has not been routinely set by orthodox military teaching at all. In the process of commanding, Ren Di had a very close relationship with the entire command team, and was very good at perceiving some wonderful and beneficial military ideas in the team. And through the practice of the army, the successful experience will be quickly amplified.

If you want to talk about Ren Di's combat style, it is basically to grasp the success, and it seems that he has suffered a loss, and the success is not great, then he will not make an appointment. When Bei Liang and Chang Shengchong began to maintain a defensive posture in the second half of winter, they waited for two months and put countless efforts on defensive buildings, but they just didn't wait for Ren Di's large army to come. The cold wind blows on the land of Liaoning, in addition to being quiet and quiet.

What is Ren Di doing now? The 200,000 troops were trained, and a large number of enemies were effectively eliminated by using the winter climate and terrain, which was earned in Ren Di's book, of course, Hai Song gave up Changchun in order to reduce consumption, which was an unexpected big profit for Ren Di. As for Hai Song, who consumes vital forces next, dies in the absence of heavy firepower, and can continuously transport troops, this seems to be a bit of a loss.

Ren Di's current footnotes are all over the north and south banks of the Heilongjiang River. There is no Maozi in the way in the north, and it is refreshing to walk in the northeast. This time, you can dig mines wherever you want, and build dams in that place if you want to build dams. The entire Heilongjiang River Transport can be completely naturalized as a whole.

A violent explosion sounded on the limestone mountain, and the large limestone mountain was still rigid and powerful a second ago. In the next second, it shattered inch by inch like tofu. The power of explosives will open up the mountain. Of course, Ren Di also cheated here, walking around the mountains, softening some of the mountain structural materials, and the power of blasting spread more widely on these softened mountains, and the depth of cracks was deepened.

A large amount of limestone is transported to the lime plant, and the lime kiln steam is lined up, steaming hot. At the high combustion temperatures of coal mines, limestone and other materials turn into cement.

In the Daqing area, dozens of tons of drilling machinery are fixed on the black soil and excavate towards 1,200 meters.

The fifteen steel buildings of the steel plant in Yichun have been built, and the exterior of these towering buildings seems to be a steel structure in the shape of various scaffolding, and huge metal pipes are connected to it, which is a blast furnace, the exterior is made of steel structure as a furnace shell, and the interior is a refractory brick, and the pipes are to control the entry of hot air and add various materials to adjust the temperature of ironmaking materials. Ironmakers can control reactions in the furnace by rotating the steering wheel-like gate on the pipe. The whole steel plant is like a building made of various steels, without the slightest exposure of refractory bricks and red bricks, this is a very advanced steel plant, the design standard is to produce 500,000 tons of steel per year. Its composition structure is all kinds of homogeneous steel processing, which the workers' and peasants' regime in Northeast China does not have under normal circumstances. But Ren Di let it have. Now it can already provide steel rails for the construction of railways in the Heilongjiang River basin in Northeast China. And, of course, a wide variety of weapons materials.

Winter was supposed to be a time of agricultural slackness, but there was no agricultural idleness, and the 50-kilometer railway from Yichun to Hegang, with wooden sleepers and steel rails, was quickly laid by the army returning from the front line and the organized masses.

As for the Yichun line, a large number of sled-pulled materials were sent to the railway section. Just like the construction of the real-time strategy, the Heilongjiang River basin is undergoing drastic changes this year. Market capital regulates unimaginable changes in production. This is the wartime economy, not for living, but for survival.

Under this economy, the target of the battle was the 20 million people controlled by the Northeast Republican Army.
