Seeing at least 80,000 people retreat into the mountains west of Shenyang, the goal of the Hai Song attack to occupy the land was achieved, but the strength of the Republican Army was not achieved by destroying as much as possible.

Beiliang is now faced with the problem that all invading armies face, 1: either stop and stabilize the occupied area, and then continue to advance. 2: Continue to advance, completely defeat the local formed forces, and then carry out the clearance of the occupied areas.

These two questions are not two separate questions, but problems that are connected together. If 1 is chosen, then the occupation forces will encounter a situation where the regular troops guarding the territory are not completely wiped out, and the guerrillas who are sweeping the occupied area are trying to wring out a sponge in the water. It is not clean at all, and after a sweep, there is a large area of frontal battlefield forces that produce food and weapons, and in order to reduce the pressure on the frontal battlefield, they will once again put their forces behind enemy lines. Spread the battlefield as far as possible. The guerrillas could not be swept away at all, and the spring breeze blew and reborn.

If you choose 2, you will win directly on the frontal battlefield, crush the regular army force, and make the rear guerrillas a source of water, the Yuan Dynasty is like this, when the invasion, the Southern Song Dynasty revolted everywhere, but unfortunately there was no cooperation from the regular army, and the result was extinguished by the Yuan army one by one.

However, if 2 is chosen, it is necessary to take down the regular army of the defending army in a short period of time, and completely destroy the mines, factories and farms of the frontal resistance forces, so that they cannot organize the frontal resistance forces. If the main strategic goal of destruction cannot be achieved in the short term, what will be the consequences if the time drags on? Well, it seems that this world Napoleon has not yet been born.

So I can, as an excellent leader of the Anti-Japanese War. Do you want to divide the rear of the enemy line and the front into two parts? To suppress or even belittle the role of one side, it can only be said that such a force that dominates the War of Resistance is really not a good leader.

Nearly 100,000 republican troops in the Tongliao area, some of them were transferred to Chifeng, the mountainous areas near Jinzhou, and some of them were transferred to the Xing'an League area, relying on the supply of railway lines across the mountains to maintain their resistance in this mountainous area.

As for the 200-kilometer front of the Hai Song Dynasty, the frontal forces of the Republican Army began to assemble on a large scale in Songyuan City, on the banks of the Songhua River. Such an arrangement is tantamount to hooking your fingers and letting Hai Song come over to fight.

As for Beiliang's choice, Beiliang will definitely not choose 1, completely pacify the rebels in the rear, this can't be pacified at all, even if the republican army troops of the Chifeng Jinzhou generation are finished, they will also implement supplies from Chengde Pass, and a simple road for the republican army to cross the mountains has been built. The signboard of the Republican Army is guerrilla warfare, and Li Ziming was in the southern mountains when he was driving around the Ming Empire in the southern mountains, and the scene of the four group armies going around in circles has impressed the military experts in this world without a deep impression. As for the active republican army in the Great Khing'an Mountains, it is even more impossible for Hai Song to go up, and a railway is no joke in this mountainous area.

At present, due to the threat of the frontal battlefield and the rear battlefield in the northeast, Hai Song cannot get the material frontal output of the northeast land at all. All farmland and mines, due to the unsafe production environment and arbitrary expropriation, skillfully seized land annexation, a large number of production waste.

The Hai Song Dynasty was a high consumption of maintenance in the Northeast Battlefield, and it was already the limit of the maintenance of the Hai Song overseas war. Hai Song can't tolerate procrastination. Faced with the build-up of the Republican Army in Matsubara City, Kitarashi immediately chose to attack this goal.

The commanders of several Haisong armies had just arrived in Changchun, and within a few hours of announcing the recapture of this symbolic position, they ordered them to move forward with a military order to move forward. There are many of the group army commanders of these Hai Song Dynasty who are the children of the side branches of the patriarchal families. Dealing with Beiliang's order of the patriarch, there was no shortage of ridicule for Beiliang in private: "I don't want to stay in this sad place for too long." The implication is that these people who easily occupied Changchun are very level. It's a gag of course. But these army group officers had no idea how the war would happen.

Ren Di is now in Harbing, looking at a military map, and the chief of staff next to him keeps measuring the distance between two points on the map with his hand, and then calculates it through the scale. The military map is different from the ordinary civilian map, which is not marked on the ordinary map, but the sheep intestine trails that can shorten the distance between the two places are thoroughly marked, and the terrain is different, whether there is forest and grass to cover it. Whether there is a river blocking it. All these factors were actually measured in order to calculate the approximate speed of the troops' march.

As for Ren Di, he doesn't use the length of his hand to compare the map, Ren Di's so-called high intelligence and high perception, the specific multi-kill distance, you don't need a ruler to measure, you can see it at a glance. The city of Matsubara was built in 1693 on the plane of Rendi. On the plane, Wu Sangui, with the support of Hai Song, after occupying the northeast, in order to control the Songhua River Plain, built a city here according to the advice of Hai Song's technicians. Originally, the city was for military purposes. However, with the absence of war in the Northeast. There was no chance of a resurgence in the post-Jin era of firearms, and the city began to develop towards a gathering place. When the Republican Army developed the Heilongjiang River Valley, the city became an important light industry production area for the Republican Army. Quilts, military cans, and military horse breeding are all here. As for now, this is a defensive position.

The headquarters where the war broke out was the most lively place, and the sound of ticking telegrams was endless, and the situation of the headquarters getting information about the war situation came from the transmission of telegraphs. On the front-line battlefield, after discovering the enemy in the distance, one by one reconnaissance units immediately ran to a hidden place in the jungle bushes to send out wireless spark telegrams. Some of these telegrams were in the tunnels under the stoves of abandoned houses, and some were in the tunnels of wells. There are even hidden bunkers in the woods. Hai Song, who was in a hurry to advance, did not know that his army was exposed under these hidden eyes. This information is gradually aggregated to the front line, and then analyzed and gradually marked on the map.

Ren Di's head in the command room turned faster and faster, in the noisy room, the telegram ticked sound, Ren Di listened carefully, and then compared the encrypted telegram book, Ren Di gradually felt that he understood the meaning of the telegram according to the syllable frequency of the telegram. Before the telegram was translated and sent by the staff, Ren Di had already received the approximate meaning of the telegram.

"The location of telegram No. 7, the codebook is Jin Zhumei, the codebook of telegram No. 6 is Jinghuayuan, and the codebook of telegram No. 5 is the Chronicles of the Three Kingdoms" Ren Di's mind quickly turned, and the above passwords were all in one of the many chapters of a book. Ren Di basically listened attentively to the syllables of the telegraph position, and compared them with the codebook of that location. Read it out quickly. Ten hours ago, only one telegraph position could be heard, but now three telegraph positions can be heard. From trying to judge in a rusty way, to now being as fluent and fast as listening to a language.

"Oil Seller" takes a gourd and places it on the ground, covers its mouth with money, Xu uses a ladle to drain the oil, and enters it from the money hole, and the money is not wet. Because he said: "I don't have him, but I know it." Or in the early days of liberation, some salespeople could achieve the same accuracy as electronic scales with their hands, reaching the point of grasping them. These things seem extraordinary, but they are all done by ordinary people. These people are determined to do it, so they have done it to a level that is unimaginable to ordinary people. And now Ren Di is determined to win, evolving to load a huge sense and intelligence. Step by step to extraordinary effect. For example, at this point, this is the situation where Ren Di's ear hearing perception and brain thinking are coordinated to synchronize operation. As for why, because Ren Di wanted to win, he felt that the telegraph was waiting for someone to decipher it, which was too slow, and Ren Di was in a hurry and decided to listen to it himself. This is the path of growth for the evolution of senior officers to harness a vast intelligence. No matter how strong your intelligence is, it's still scum, and if you don't try to use it, it won't have much effect after all.

High intelligence is not king, and there are too many distractions, such as fear and fear, and the feeling of comfort and enjoyment, which are several times higher than that of ordinary people. Smart children are sometimes more likely to indulge in games than stupid children, and this is the reason, because under high intelligence, the external interference is also increased, so they do not use high intelligence to decide their own fate.

"They're coming?" When a piece of code sounded on the telegraph, the telegraph operator at the position seemed to understand part of the meaning of the telegram, and hurriedly translated, Ren Di had already read the information clearly, and Hai Song's troops had arrived.

Propeller fighters, on the runway behind Matsubara Castle, took off, and from the sky you could see a mirrored river crossing the city complex. On the flat earth, the green land of the revival of the city river is mundane and magnificent.

As Hai Song's army approached Matsubara Castle, the Republican army in the sky began to launch air strikes against Hai Song's assault forces.

The combat vehicles on the ground shot long points of light dragged out by tracer bullets into the sky, one after another in a line, and the rotating steel machine gun turret tried to capture the planes hovering in the sky with the line of fire, but the fighters in the sky circled and threw a few rockets towards the armored troops on the ground. Under the thrust of the tail flame jet, a rocket spiraled through the steel armor of the armored vehicle, hit the edge of the track, burst into a blazing flame, glued to the track, and quickly turned into a hot wheel as the track turned.

White phosphorus, this thing is an incendiary weapon that the Republic can obviously produce at present, as for the higher-level thermite burning # incendiary bomb, then there must be electricity first, as for the power industry, the Republic is still experimenting with various technologies.

In the dense barrage of innate air, planes fell, and under the blows of planes, there were also chariots burning with flames on the ground. This will be a symbol of the war at the highest technological level at this time. As Hai Song's army gradually arrived and the airstrip was built, Hai Song's fighter jets appeared in the sky, which were obviously faster than the Republican army's fighters, and their various turning movements were more agile.

The air units of the Republican Army had to turn their focus to air power against Haisong. The Great Air War broke out. Both sides use machine gun shuttles, drawing lines in the sky, chasing each other. From time to time, wooden wings were shattered, and a forced landing site had to be searched. Note that the Republican fighters in this era have not yet been crushed by the Hai Song, although the engines of the power Republican Army are insufficient, but the planes of this era are made of wood, and the weapons on both sides are machine guns that can break through wood. In this way, it is equivalent to a twelve-year-old child and an adult man both holding guns, and both must face the guns in their hands. The bodies of both sides were very fragile in front of the gun.

This is how it is now in the air war. With the continuous development of the aviation industry and the advent of the era of all-metal aircraft, after the geometric multiplication of the capacity of the aero engine, it will be more and more difficult to capture the aircraft with more and more speed and power, and the engine will become the key to determining the victory or defeat of the air.

The structure of the machine gun coordinator is not difficult, but Hai Song and the Republican Army did not struggle for a long time as they did in history. The two sides directly reached the era of passionate air combat with machine guns firing at each other in the sky.

Air supremacy, only by completely eliminating the existence in the sky of the other side can it be said to take air supremacy, and the pursuit of each other's aircraft groups in the sky above Matsubara City began to intensify. Three of the Republican Army's forward airfields were blown up by Haisong's aircraft group, forcing the Republican Army to place the aircraft group twenty kilometers behind Songyuan Castle. Similarly, the airport in Haisong was suppressed fifty kilometers away from Matsubara Castle. Since the two sides could not control air supremacy, there was no chance that a group of bombers would be able to use a slower bombing speed. Let the world see the power of carpet air strikes. Therefore, the army is still the protagonist of the contest.
