The Republican Army conquered the Changchun area of ​​Jilin, and the result of annihilation and captive of Hai Song 561 was announced when Hai Song retreated. This was already the fourth army organization that Hai Song lost in Ren Di. With the losses of guerrilla warfare, it is conservatively estimated that Hai Song permanently lost its troops to 180,000. Such failures are injustice in front of any country. But there is only one country in the world who can (stuck tape).

However, after encountering such failure, the normal national leadership decision-making team began to consider giving up this war with losses exceeding the budget after thinking about the pros and cons of occupation. However, Hai Song's leader's vision was as profound as that of Jiang Gong, and it was obvious that his competitors in the next fifty years were here. He did not change players at the last minute, and he proudly left more than 100,000 troops to a veteran as the tuition for training on the battlefield.

When the snow passed by the clear sky, a rocket shot from the blue sky dived down from the sky and hit the thick Chenyang city wall, only a few bricks covered with ice collapsed, meaning that the Republican army's offensive against Hai Song could only end here. Because there were no heavy artillery, it was no longer practical to rely on rockets to fight the tough battle. The city of Chenyang is the base camp built by the Wu family army to guard the northeast, and it is not an exaggeration to be an fortress-type city.

Rocket launchers, light mortars, killing infantry, and destroying bunker houses is almost the same. To really deal with this kind of steel and concrete structure with a wall of one or two meters thick, it must be used to attack the tough, or bombard the aircraft carried by large-scale aircraft. However, these are still a problem in the final analysis. The Republic is now unable to create power machinery that moves large-scale war machinery. Faced with such a hard city wall and a series of defensive structural buildings, Ren Di can only need gas turbines to traction trucks, tanks, and fighter jets.

As for the blasting of civil fortification tunnels, there are now several shovels in the northeast permafrost layer and they cannot be dug at all. As for the tanks, Ren Di tried to make them, whether they were pistons or gas wheel engines, but this thing was stuffed into a steel shell and formed a chariot, which showed fragility when it formed a whole.

The rock is harder than our skin. We can't hold a stone from the ground, but we can't hold it to pieces (the dead side of sandstone). However, a piece of stone that is one millimeter thin, we can easily pinch the piece of stone into powder with our thumb and index finger. It is not that the skin on our fingers is harder than the rock. It is chopped rock, but that the force that the rock piece is unbearable on our fingers is applied to the unbearable force of the rock piece. The same is true for steel. If it is a whole iron rod with a diameter of one decimeter, it can naturally withstand a large amount of impact. However, the engine, the countless fine steel parts, bear the power of fuel explosion, and the output force is a steel machinery of several tons. The force that pushes such a large machine is equivalent to the engine that outputs energy, just like our fingers pinch a piece of stone.

Ren Di's tank production experiment was very failed, with engine parts broken and gears crashing. If such a tank went to the battlefield, forget it, don't take this crime.

Of course, there is another problem with large-scale mechanization, that is, oil. In terms of oil, the famous Daqing is located about 150 kilometers northwest of Harbin. The location of the Daqing oil well is exactly behind the Republican Army. Current technology is just enough to be mined. Well, but it just can be mined.

The Northeast of this era was still too desolate. Why? Vladivostok is still a fishing village now. Hae Song has a series of natural unfreezing ports such as Sasebo and Busan, and there is no interest in opening port cities on the coast of the ice field north of Heilongjiang. As for ports such as the Ming Dynasty and Dalian Lushun, the threat of Jurchen savages in the northeast was eliminated, and it was equal to a natural invincible state in the northeast. There was no economic benefit to opening a port in Vladivostok.

This is true for ports and railways. The railways in the northeast are all concentrated in the Chenyang area of ​​the Bohai Rim. As for the Heilongjiang River Basin in Harbin, there is no trace of industry. Even the railway in Changchun was only stayed on the desk of the Ming Dynasty in 1700 and did not become a reality. The population of 40 million in the northeast was about 25 million in Liaoning in the Bohai Rim area. The Liaoning area is also an important base for Wujia coal and iron industry. One iron and one coal in Anshan and Fushun were just gathered together for him. Of course, this coal and iron was finally a factory that Haisong provides technical and technical workers, as well as a core component. The industrial output value of the entire northeast area includes more than 50% of the entire northeast. As for the coal mining industry in Xing'anling, Heilongjiang, there is no industry in the north.

With the support of Liaoning with the support of steel bases and military factories, as well as a developed road network, it is basically difficult to fight the Republican army that came from the north without heavy weapons. If you want to fight, you can only start from the edges and corners.

Ren Di calculated his strength, well, let's forget it, it's better to get the railway line built. As for Ren Di now building his own coal-iron base. The large area of ​​land controlled by Ren Di is not useless. There is such data in the 21st century grain production data. Liaoning's grain output is about 5 billion jin. Jilin's data in 2011 was 65 billion jin, and Heilongjiang Province's grain output is about 85 billion jin in the country. Of course, this level of grain output is not expected to be achieved now, but it can be seen that the potential of this door-shaped land is included in the Northeast Asian continent, the Great Xing'an Mountains to the west, the Xing'an Mountains to the east, and the Great Xing'an Mountains to the north. The potential of this land is the Ming Empire that was not able to develop it. Hai Song could only temporarily penetrate Liaoning by the port.

The wartime system was not just for war, but also for economic construction. Millions of laborers were engaged in industrial and agricultural production, grain planting, and coal mining. The entire Northeast Workers and Peasants Government operated like a machine. The northeast of the Northeast is not bounded by Heilongjiang, and the specific geographical location should be bounded by the Xing'anling. As for the Russians, they are still fighting with Turkey and dare not come to the east to find fault. The troops that were looking for faults were all cleaned up by Yun Chen and Yili.

There is no iron ore on the south bank of Heilongjiang, but on the north bank of the lower reaches of Heilongjiang, there is the place on the top of the big cock in the Rendi plane of the Rendi plane, which contains an iron ore with a reserve of one billion tons, corresponding to the coal mine on the Xing'anling on the south bank of Heilongjiang. This is why the steel plant was set up in Yichun in the middle.

Food, coal and iron, plus the population migrating northward. This is Ren Di's current strategy. Under this strategy, Ren Di does not want to fight Nogi Hidun's tactic of meat #Keken City. If the army consumes too much, it must be supplemented from the production population. In the future, there will be heavy steel artillery, large areas of land need 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 support within the entire Chinese pass. This support can enter the Northeast for combat as long as the Jitong Line is opened.

When Changchun conquered and the front line was compressed again to the border between Jilin and Liaoning, the two sides reached a stalemate again, although from a territorial perspective, the Republican Army overwhelmed Hai Song's expeditionary force in a corner of the northeast.

Zhao Weiguo has moved the provisional government to Zhengzhou. The Northeast Battle has to some extent involved the development of the entire country. When Changchun conquered, the Republic's Provisional Government was excited. Zhao Weiguo sent a telegram to the Northeast: "Is there a decisive victory in the near future?" Ren Di said clearly: "We can only achieve this point now, and the battle against major cities will be fought with the national industrial forces."

The Northeast Battle did not end for a day, and the strategic location of the capital of the Ming Bohai Bay was unsafe. Zhao Weiguo's telegram seemed to remind Ren Di, and Ren Di immediately sent dozens of telegrams, asking for mechanical parts, skilled workers, doctors, agricultural technicians, and mineral technicians. Zhao Weiguo saw this large number of telegrams that were full of urgent tones like snowflakes, and was amused and cried. He was obviously beginning to gain the upper hand, and it was like he was about to perish tomorrow.

But after thinking about the strategic location of the Northeast, Zhao Weiguo gritted his teeth and gave Ren Di everything he wanted. 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 could not sit still in Jiujiang, so he directly set the temporary government in Zhengzhou, and then supervised the construction of the Jitong Line every few days.

The battle between the new Republic and Hai Song was already at the level of a total war. Now in the second half of the winter, the front line on the northeast was strangely calmed down. The war in the Liaoshen area suddenly calmed down. Ren Di's cold and hot war was shocked by all observers at that time. For a time, Hai Song, South Asia, Northeast Asian Islands, and major European newspapers began to speculate on what Ren Di's combat style looked like. Since Ren Di's debut, a series of battles, including slippery mobile warfare, quick and thunderous annihilation war, and the wildness of just annihilated the two armies of Hai Song on the northeast. It seemed that Ren Di's specific combat style could not be seen. This changeable, the battlefield magician, the outside world began to give Ren Di this title.

But in fact, decades later, as a large number of people began to write memoirs of Ren Di, they understood the reason exactly. Since Ren Di's debut, the military command and staff team has been changing. Most of this team was not professional, and its style was not scheming by orthodox military teaching routines. Ren Di had a close relationship with the entire command team during the command process, and was very good at detecting some wonderful and beneficial military ideas in the team. And through military practice, he quickly amplified his successful experience.

If you want to talk about Ren Di's combat style, you will basically be successful if you are sure of success. It seems that you are at a disadvantage and have little success, then you won't make an appointment. When Beiliang and Changsheng Chong started to maintain a defensive posture in the second half of the winter, they waited for two months and put in countless efforts on the defensive buildings, but they didn't wait for Ren Di's large troops to come. The cold wind blew on the land of Liaoning, which was also quiet.

What is Ren Di doing now? The 200,000 troops were trained and effectively eliminated a large number of enemies by using the winter climate and terrain. This was a profit in Ren Di's notebook. Of course, in order to reduce consumption, Hai Song gave up Changchun, which was even more unexpectedly profitable. As for Hai Song, who consumed vital power in the future, and fought to the death without heavy firepower, he could transport troops continuously, this seemed to be a loss.

Ren Di's current footnotes are all over the north and south river basins of Heilongjiang. There are no Russians in the north and it is a big pleasure to stroll around the northeast. Now, if you want to dig, you can dig the mine wherever you want to build a dam. If you want to build a dam, you can build a dam in that place. The entire Heilongjiang River transportation can be completely naturalized.

The violent explosion sounded on the Lime Mountain. The large limestone mountain was still strong in the first second. The next second it was shattered like tofu. The power of explosives opened up the mountains. Of course, Ren Di also cheated here, walked around the mountains, softening some of the mountain structural materials. The power of blasting spread wider on these softened mountains, and the depth of cracks was deeper.

A large amount of limestone was transported to lime factories, and the steam was arranged in lime kilns, emitting hot air. At the high temperature of the coal mine, limestone and other materials turned into cement.

In the Daqing area, dozens of tons of drilling machinery were fixed on the black soil and dug toward one thousand two hundred meters.

Fifteen steel buildings in Yichun's steel factory have been built. The exterior of these towering buildings seems to be steel structures of various scaffolding shapes, with huge metal pipes connected to them. This is a blast furnace. The outside is a steel structure as the furnace shell, and the inside is refractory bricks. The pipes control the entry of hot air and add various materials to adjust the temperature of iron-making materials. Iron-making workers can control the reaction in the furnace by rotating the steering wheel-like gate on the pipe. The entire steel factory is like a building built by various steel, without any exposed red bricks. This is a very advanced steel factory. The design standard is to produce 500,000 tons of steel annually. Its composition structure is processed with various uniform steel materials. It was originally not available under normal circumstances by the Northeast Workers and Peasants' regime. However, Ren Di let it have it. Now it can provide rails for railway construction in the Heilongjiang River Basin in the Northeast. Of course, there are various weapon materials.

Winter was originally a slack season, but it did not come to slack season. The 50-kilometer railway from Yichun to Hegang was quickly laid out by the army returning from the front line and the organized masses.

As for the large amount of sledding materials on the Yichun Line were sent to the railway section. Just like the construction process of real-time strategy, the Heilongjiang River Basin is undergoing drastic changes this year. Market capital regulation of production is unimaginable. This is the wartime economy, not for the purpose of life, but for the purpose of survival.
