After the arrival of the Japanese planes, they were still the same, hovering at the edge of the range of the Dongku anti-aircraft guns, and did not come close.

Dong Ku didn't care at all, if he didn't get close, he wouldn't get close, anyway, it wouldn't affect the bombardment, and the attacking troops were always prepared, once the opponent's shells could not bombard intensively, then they would rush into the Japanese position, and if they didn't make a move to break through the whole line, they would also tear apart the Japanese defense line and engage in hand-to-hand combat. Although the advance army was not necessarily stronger than the Japanese in white-knuckle combat, it was better to equip each person with a shell gun, and would not engage in white-knuckle combat with the Japanese army at all, nor would it give them a chance.

But at this moment, in the rumbling cannonball, a shell landed on the edge of the anti-aircraft artillery position at the southern end, and a huge wave of air lifted the camouflage net, and several nearby soldiers fell in a pool of blood.

Hearing the explosion behind him, Dong Ku was clever and asked loudly: "Where are the shells from?!" ”

Soon, the observer of the attacked position, based on the sound of shells heard in advance and the point of impact, deduced that, although there was no specific location, the direction of the big cover, the front of the Japanese position.

"75 mountain guns were set up at the front of the Japanese position?"

Dong Ku was startled and hurriedly raised his binoculars.

The Japanese mountain artillery appeared in the front line, and the front end of the anti-aircraft artillery position was completely exposed to the enemy's firing range, which would be a big trouble.

However, in the smoke of gunfire, he could not see the situation in the distance at all.

At that moment, he clearly heard the sound of cannonballs flying, and not one, but at least three.

"Position No. 1 and Position No. 2, with an effective shot of 651 ...... 78, left and right correction 3 to both sides of the second shot! ”

Before his shouts fell, there were several loud bangs, and an anti-aircraft gun and an anti-aircraft machine gun were hit by shells, and the fragments flew around, killing all a dozen fighters around him. No one was spared.

Ten seconds after the explosion sounded, a shell flew again, and landed on an anti-aircraft gun truck with a thud.

With a loud bang, the truck burst into flames, and the camouflage net began to burn.

"Extinguish the flames!!"

The surrounding fighters did not panic, they were already equipped with a large number of dry powder fire extinguishers. This is something that has only been mass-produced in Dongku Industrial Park for a short time.

As patches of white fog rose, the burning trucks quickly extinguished, and the camouflage net stopped the spread of the fire.

"The front-end anti-aircraft artillery retreated for a kilometer, the camouflage nets were all put away, and the shells were not allowed to remain on the ground!"

Dong Ku looked at the busy figure in the distance, and when the artillery roared here, he gave the order to retreat.

During his order, there was a loud bang from the Japanese positions in the distance, and a huge ball of fire rose in the direction where the shells were flying.

After the loud bang. Another round of shelling, the fire began on both sides of the first loud bang, and rose within one or two hundred meters.

After two rounds of shelling, Dong Ku looked at the Japanese position in the distance in the telescope, and his expression became solemn.

The shells just now flew to show that the Japanese army had transported the artillery to the front of the position, and cooperated with the bombers to countermeasure the artillery here, and a bitter battle was coming.

Did they disassemble the artillery. Shipped to the tunnel?

Dong Ku's guess is really right. It was the Japanese who dismantled the mountain artillery and transported it along the tunnel to the front line. Reassemble again. It's just that due to the height of the tunnel, they have no other way than to dig deep into the ground to place the artillery, and the firing port of the bunker is very small, and disassembling the wood will also affect the firmness of the tunnel, so. It is only possible to use the limited angle of fire of the shooting hole to shell the coordinates to be bombarded.

The effective firing did not accidentally kill all the Japanese soldiers in that area of four mountain guns, but this did not stop the artillery firing.

As the second wave of shells flew, more than a dozen mountain guns were erected, and in two minutes after the loud bang. Shells fell one after another on the evacuated anti-aircraft artillery positions.

With the explosion, one machine gun, two anti-aircraft guns were hit, and dozens of fighters fell in pools of blood.

"Non-stop shelling of the shelled area from all positions!!"

The constant explosions made Dong Ku see the crisis, stopped the offensive shelling of the Japanese position, and concentrated all the artillery to the position of the shelling.

The Japanese machine, still not moving at this moment, is still circling, outside the Dongku anti-aircraft artillery area, not forward.

The shelling here played an operational role, and the cannonballs did not fly.

But Dong Ku didn't dare to be careless, he made Junko ready to attack, and wanted to use the attack to force the Japanese plane to fly to support.

But just as he gave the order, in a whistling sound, more than 30 shells flew from the Japanese positions in front and flew towards the anti-aircraft artillery positions.

Without waiting for the shells to fall, the Japanese planes hovering in the distance aimed in the direction of the position, and the engines screamed and rushed straight at them.

"Artillery interception!!"

In the sound of the explosion, Dong Ku's order was conveyed.

The anti-aircraft artillery roared in the violent explosion at the front of the position, and one shell after another was fired into the void, in the direction where the Japanese plane was flying.

In the clouds of smoke in the sky, the Japanese planes were constantly destroyed by steel balls, but they did not stop their moths from fighting the fire.

At the southern end of the anti-aircraft artillery position, at this time, nearly half of the anti-aircraft machine guns and machine guns were destroyed by the round of bombardment just now, and even the nearby light machine gunners were also affected, so that the originally woven large net appeared vacant.

The cannons on this side did not use Dong Ku's orders, and they were in a group of ten, locking on their respective targets, and the effective fire bombarded the past.

However, the Japanese did not concentrate their artillery this time, but scattered them in the entire first line of defense, stretching thousands of kilometers away, and only aimed at the southern end of the anti-aircraft artillery position, ignoring the nearby anti-aircraft artillery, the intention was very simple, that is, to tear a hole for the Japanese plane, in order to destroy the position here.

This time it was broken, although the Japanese were directly killed in the shelling, they were almost lined up in the tunnel, as long as there was a loud noise at the front, the corresponding artillery here would fly up, and the corpses would be dragged out. As a result, the shells rained down on the southern end of the position without stopping.

In the distance, the 105 heavy cannons of nearly 200 men did not stop, and the barrage blockade was implemented at the front end of the position, and even those heavy artillery with a range of 15 kilometers and 13 kilometers roared at this moment, obviously preventing the advance army from a possible attack.

The Japanese shells successfully tore a hole in the anti-aircraft guns at the southern end, and they were still extending inward, to both sides.

At the same time, the Japanese planes, which had broken through the first barrage interception, roared and dived towards the anti-aircraft artillery positions regardless of it.

Dong Ku, who had already seen the figure of the Japanese fuselage, shouted: "All defenses are on!" ”

With the order of Dong Ku. All the antiaircraft guns concentrated on meeting the dozens of enemy planes that flew in, the machine guns roared, the shells flew into the sky intensively, the antiaircraft machine guns were full of fire, and the bullets of the antiaircraft guns cut through the void several pieces, and the bullets of the light machine guns formed a dense interception net.

The advance army clearly underestimated the mania of the Japanese army to advance bravely. The Japanese planes did not intend to dodge at all, but Fu Chong, directly hit with the plane, in the front of the ground explosion of the fire, the sky bloomed with fire, the festival fireworks like splendor, but this still could not stop the flying Japanese planes, one after another was hit but did not disintegrate the Japanese planes hit the ground straight to the ground, hit the vicinity of the anti-aircraft artillery position.

Rumble!

A heavy Mitsubishi series bomber at the moment of hitting the ground. There was a shocking bang, and Zhan Dan inside had obviously installed a fuse, and in the impact, it was directly detonated.

The violent explosion destroyed everything within a hundred meters of the surroundings, and the light machine gunners who were close to there did not have time to react and directly vaporized.

The shockwave swept through the area all the way, and although it failed to destroy the approaching anti-aircraft guns, the warriors were in the midst of this loud noise. One by one dizzy, let alone jerk off. I couldn't even see the shells that came up from the pit under the ground.

Dong Ku looked at the suicidal Japanese machine, he kept his calm, he knew that the big war he was waiting for was coming, and the Japanese opportunity was pouring out, and the loss of these cannons. He's just going to replace those planes.

He took a deep breath and shouted, "Anti-aircraft artillery position, the second plan!" ”

With his roar, all the anti-aircraft artillery teams, heavy machine gun teams, and machine gun teams guarding the phone heard it. Subsequently, some of the mobile anti-aircraft guns began to move, shrinking closer to the main attack of the Japanese planes, plugging the gap that had been torn apart. And those immovable fixed anti-aircraft guns are tightly blocked with the barrage of love that gap. In the dense rain of bullets, I am afraid that not even a fly can fly over it.

Just as Dong Ku adjusted the defense on this side, the shells of the opposite position fell without spending money, and the shelling of this side continued, and the second wave of attacks by the Japanese planes also arrived.

Before all the planes in the first wave fell, the Japanese planes charged in groups, and the path was still the same, starting to dive from a few kilometers away, using the dive to accelerate. And bombing and strafing were obviously not their purpose, they were just like in the Battle of Midway, using aircraft bombs to directly hit and create a bombing opportunity for the attacking troops behind.

The battle, at this moment, was immediately white-hot, and all the fighters held light machine guns and sprayed tongues of fire into the sky. All the anti-aircraft machine guns also opened fire with all their might at this moment, and the machine guns continued to roar, throwing dense projectiles into the air.

The fire of the anti-aircraft artillery has not stopped, according to the distance of 3,000 meters, 2,000 meters, and 1,000 meters, constantly spraying steel ball barrage, firmly blocking the airspace of that area.

The frantic attack made the anti-aircraft guns on the truck still fire in motion, and at this moment, all the anti-aircraft guns on the position moved, and only fifteen machine guns were not lacking to prevent the fish from slipping through the net and rushing into the position.

The Japanese planes didn't seem to care about the smoke that was waving, nor did they care about the large metal net woven in front of them without any gaps, and the pilots roared one by one, accelerating desperately, and crashing straight into the ground.

In the sky, the loud roar continued, one after another planes exploded violently in the air, and one after another fell to the ground with thick smoke, but unexpectedly, none of them parachuted out.

The sky was quickly covered by thick smoke in the violent explosion in the air, and even the sun was no longer so bright, emitting a dark red, often obscured by the smoke clouds.

"Enemy planes approached from the position at three o'clock !! With a height of two hundred and a speed of four hundred and five or more, it is a flamingo!! ”

During the fierce battle, the listeners found the sound of the engine in the violent explosion, and warned the flamingo when it was 3,000 meters closer to the position.

With the shouts of the monitor, the anti-aircraft guns and machine guns tied to him immediately turned around and aimed in the direction where the flamingo was flying, and without waiting for Dong Ku's order, they had already fired.

There were a total of thirty flamingos, this was the most powerful new fighter plane from Terauchi Shouichi, they all carried two sixty kilogram bombs, plus twenty machine guns, destroying the anti-aircraft guns was like playing.

The barrage was a bit slow to form, and when the anti-aircraft shells flew into that airspace, the flamingos were all swooped down and passed through the first interception, except for four that were hit by the oncoming shells.

"All the machine guns and machine guns at three o'clock stop the flamingos!!"

Dong Ku clenched his fists, stared at the direction of three o'clock, and yelled to order.

With his command, all the machine gunners in that area aimed their guns in the direction where the flamingo was flying to the roar of the group leader.

However, one of the flamingos was fast enough, and at this time it had reached a maximum speed of 500 kilometers per hour, and the other was approaching quickly under the cover of the fierce battle at the southern end, so that the interception on this side was not timely.

The flamingo's flying fuel tank followed them and swooped down towards the ground, and the machine gun in the nose had already spewed tongues of fire, and at the same time as the ground machine guns were pumping into the camp of the unprotected fighters on the ground.

In the blood mist, one after another flamingos were cannon fired. The anti-aircraft machine gun hit, and there was a violent explosion directly, igniting a large fireball that soared into the sky and fell to the ground.

As the front was hit and the fire broke out, the Japanese machine behind did not hesitate to burrow into the flames and continued to pounce forward.

The warriors were in the loud noise, and at the moment when the flames pounced, they could no longer dodge, and many of the soldiers were on fire.

The soldiers with fire extinguishers in their hands pounced on the moment the fire fell, and in the bursts of white fog rising, the flames were extinguished in just a few seconds, and most of the soldiers were temporarily free of life except for burns.

At the moment when they saw that they were about to stop this wave of sneak attacks, the three flamingos drilled out of the fire that was still burning in the air and threw out two bombs on the planes one after another.

"Grass mud horse!!"

The soldiers had blood-red eyes and desperately pulled the trigger in the face of the incoming plane. The battery of anti-aircraft machine guns was also drawn on the plane.

In the midst of the sparks, three loud bangs sounded in the scream of the bomb falling, and then the huge ball of fire fell to the ground only thirty or forty meters high, and then, in the loud bang, the bomb thrown by the plane fell to the ground and exploded. The furious impact burst into flames of the fuel tank that had already hit the ground and was splashing with oil.

With a bang, after the shock wave, the anti-aircraft guns, anti-aircraft machine guns, and machine guns were overturned at the same time, a huge fireball rose up, and a layer of fire waves rolled and spread outward...... (To be continued......)
