PS: Thank you for the warlord mighty ing, the big explosion Jun children's shoes Del reward, thank you, thank you!!

After Dong Ku specified the plan, he quickly transferred anti-aircraft artillery from Harbin and Shuangcheng, and transferred two-thirds of Harbin's anti-aircraft artillery to the front line of Shuangcheng. At the same time, Dong Ku ordered the formation of a machine gun brigade, with more than 5,000 fighters all Depp and crooked handles, to escort the anti-aircraft artillery positions and act as bodyguards for the artillery positions.

In addition to those peasants who have entered remote areas to open up wasteland, young people who are temporarily unable to enter the army have set up a huge support corps under the organization of Liu Canghao to transport ammunition and supplies and other materials to the front line.

In the middle of the night, forty 120 and 150 caliber howitzer positions were constructed, and thirty 75 field guns and mountain guns were brought in to deal with the grenadiers and possible mountain artillery positions and field artillery positions.

Dong Ku judged from the information obtained by Shunzi that there were still artillery positions in the depth of the Japanese army's positions, not only the 105 cannon heavy artillery positions, how could they also arrange several positions with a range of several kilometers to more than ten kilometers, but the positions were not in danger of being breached, and they did not move all of them.

After the carpet bombardment, the secret post confirmed that the enemy had retreated, and did not advance, in addition to increasing troops, they planted the damaged barbed wire and mines overnight, and in the night, resealed the torn holes. Let the position return to its previous state of iron bucket.

Dong Ku, who had been running wildly for two days and one night, had finished arranging all the matters and went to sleep at the end, and this time he did not sleep for more than ten hours as he imagined, but only five hours, and the antiaircraft artillery position had been constructed and the artillery was waking up in the middle of transportation. After a quick bite to eat, he hurried to the Twin Cities with the guards.

By the time he arrived, the positions outside the twin cities had been built, the camouflage nets were all in place, and the receivers had begun to be set up kilometers away from the point of attack, and the squads with more than a dozen sets of receivers were ready for early warning.

The position was divided into three parts, one with thirty large-caliber guns, one with thirty field and mountain guns, and one with ten 120 howitzers. All of them were also ready to attack the enemy's long-range artillery positions. And the artillery is carrying the shells, preparing for the most rear-end attack.

After Dong Ku arrived, he entered the temporary headquarters far away from the artillery position, glanced at the Junzi and those personnel who were already in place, and after understanding, he ordered: "Prepare in half an hour, start the attack at three o'clock!" ”

"Yes!"

The communications officer in charge of delivering the order quickly conveyed the order.

Dong Ku looked at the Japanese positions in the distance in the night that was not cold. Took a deep breath. Whether the Japanese army's hole cards can be lifted is today. Whether it was possible to annihilate most of the bombers of the Japanese army is also today. And today, it will be a battle to hold back the Japanese army, and he has no bottom in his heart whether it will succeed or not.

Half an hour passed, and with a wave of Dong Ku's big hand, a roar came from the position of thirty cannons.

The shells tore through the darkness before dawn and struck the Japanese positions. The earth shook and the mountains shook, and the fire soared into the sky in the distance.

The shells fell, and the 300-meter-diameter radius in front of the barbed wire fence was swept away by a violent shock wave, and there were no shrubs and weeds, and the Japanese troops hiding in the holes in the ground did not know what was going on. was buried alive, so that all the three dark sentinels in that area disappeared.

The artillery fire did not stop at the beginning, but extended along the barbed wire fence to both sides, but did not bombard in depth.

In the firelight, the Japanese troops on the position were in a panic, and the dark post in front seemed to have been discovered by the other party. Having lost their eyes and ears, what they wanted from Minlin was the furious attack of the advance army.

At the same time, Lao Zhao used 20 120 and 150 howitzers to bombard the Japanese positions piece by piece at the appointed time.

After receiving the report of artillery fire on the front line, the Japanese army's response can be described as extremely fast, artillery positions everywhere were ready, and the airport in Xinjing also began to be busy, and one after another planes left and flew into the night sky.

After clearing the barbed wire fence one kilometer away, Dong Ku turned the muzzle of the gun, hit one point, and a group of ten guns began to bombard the depth of the Japanese position vertically along the barbed wire.

Needless to say, the power of the effective shot was naturally extinguished, and when the shells fell, the barbed wire and mines all disappeared, clearing the open space with a diameter of 100 meters in one round, leaving behind large craters with smoke.

The Japanese soldiers in the position took refuge in fear in the thicker bunkers, trying to dodge the devastating shelling. But when the shells fell, they realized that more than two meters deep could not stop the violent shock.

As the shells fell, there were not many people left alive in the bunker, and even those who were alive lost the ability to control the machine guns.

The shelling continued, and after extending inward for a kilometer, it began again, again bombarding row by row.

Seeing that after the artillery fire was extended, the attacking troops could enter a position without defense, and the whimper of heavy artillery grenades suddenly sounded in the sky, and in the scream, the shells rained down, covering the range of 500 meters in the front of the barbed wire, and in the dense flickering fire, it turned that piece into a sea of fire.

"Sample!"

Dong Ku put down the binoculars, muttered contemptuously, and ordered: "Five to the left, no correction, continue to bombard!" ”

He had long expected that the Japanese army's long-range artillery fire would cover and intercept in advance to prevent the attacking troops from rushing up when the Japanese army's long-range artillery fire was unguided and the depth of the position was bombarded. And he didn't intend to let the troops center at all.

The dense explosion was drowned out by the following loud noise, and four or five hundred meters to the left of the Japanese artillery fire, the artillery bombardment of the advance army began to extend straight inwards again.

The Japanese troops on the position were miserable at this time, the Japanese troops who were crowded and hiding on both sides did not expect that the opposite side would change the location of the bombardment, a round of shells fell, hundreds of Japanese soldiers turned into dead bodies, in the dim light, the tunnels were sprayed with blood mist, and there were also fragments of lung lobes mixed in between.

As the artillery fire of the advance army extended, the long-range positions of the Japanese responded at the same time, and before they could extend a few hundred meters, the shells of the long-range artillery covered the forward positions in that area.

However, when the Japanese shells fell, the artillery fire of the advance army turned again, aimed at the position of the first bombardment 500 meters to the right, and launched an extended fire.

At the beginning of the shelling, the Japanese army moved all the nearby positions that were bombarded into the tunnels on both sides to avoid the attack of destruction, but this time, the sardine-like pile of people there was unlucky, and hundreds of Japanese troops disappeared in one round of shelling.

And then, the Japanese artillery shells flew over to intercept that piece, blocking the possible charging team, and buying time for the Japanese troops running in the tunnel to enter the position.

In the rumbling cannon, the soldiers of the advance army lay thousands of meters away from the forward position, and they had no intention of approaching, they did not receive the order to charge, so naturally they would not charge with refueling tactics like the last time.

The commanders of the Japanese army were dazed by the shelling of Dong Ku, interception, purely a waste of shells, without interception, without the guidance of the front, where would they dare to ensure that the enemy did not approach the bunker? Once you blow up the bunker and get inside, there's no way to get it, after all, the advance army's charge is quite terrifying.

"Are they going to attack on all fronts?"

In the headquarters, the generals of the Japanese army frowned and listened to the sound of artillery.

Major General Onomiya, the commander of the new 7th Division in charge of the Harbin position, frowned, listened to the reports that kept coming back from the front, struggled in his heart several times, and still gritted his teeth and ordered: "04 field artillery position support, fill the gap of long-range artillery!" ”

He had to give this order, the enemy's artillery could not determine the location of the attack, and although the 105 heavy cannon would not be destroyed by the opponent, after all, the distance was too far, twenty kilometers, and the shells would always fly for a while, so it was not necessarily possible to guarantee that the shells would be in place in time during the protruding attack.

With his order, a field artillery position three kilometers away roared, and just as Dong Ku had changed his bombing position, it landed on the periphery of the barbed wire area, and the entrance to the extension route of Dong Ku's effectiveness was blocked.

Can't hold on?

With a faint smile, Dong Ku picked up the phone and ordered, the three groups of the No. 1 position are not open, the observation post calculates the trajectory, looks for the position, and the No. 2 position is ready!

Sure enough, the Japanese army really could not judge the attack position of the advance army, as long as the advance army carried out effective fire, it would soon have more than 20 artillery pieces covering the place, so that the front of the Japanese position was under continuous artillery fire.

However, the Japanese did not know what to do, although their 75 guns were mixed with large-caliber shells to confuse the other side, but it had no effect, and in less than five minutes, the coordinates of the four 75 mountain artillery positions appeared on the artillery map.

"The four groups are separated, shoot effectively, and each lock on to the target!"

With Dong Ku's order, the artillery that had been adjusted roared, and the projectiles roared towards the artillery positions several kilometers away, and then, the loud bangs broke out one after another, and the sky illuminated by the light in the distance was clear, and the violent shock shook even Dong Ku a few kilometers away, and they felt that the ground was uneven.

The four artillery positions were destroyed without accident, and the violent explosion also destroyed everything within a kilometer of the surrounding area, and even the Japanese troops in the bunker were not spared, not buried alive, but also shocked to death, so that the piece disappeared in the firelight, became a place of death, silent.

"Airplane!! Call for Airplane Support!! Why hasn't it arrived yet?!! ”

Onomiya roared wildly, he couldn't take it anymore. Although the opponent did not launch a general attack, this momentum is no different from the attack on all fronts. (To be continued......)
