The shelling, as sharp as ever, was flying on the Japanese positions, and in just half an hour, those artillery positions had been razed to the ground.

No, it was the permafrost that flew and filled the open space under the bunker, and from above, it looked like it had been filled. The frozen soil on those bunkers was already more than a meter deep and soft, and when the shells fell, a large crater appeared, and then most of them were filled in by the falling clods, and the cycle began over and over again, and as the shock wave gradually decreased, some places faintly exposed the concrete below.

Most of the holes in the fortress guns were buried in the earth, or the Japanese blocked the holes at the beginning, and they all disappeared anyway, and the shelling only kept rolling debris and the smoke from the pits.

The fierce shelling is enough to destroy all the lives here in normal times, but Dong Ku and they all know that where they can resist the vibration of the cannon, the concrete is probably not as thin as a meter, and it is destined not to be thin.

After half an hour of shelling, tanks and Spitfires chased the shells, crossed the front line, and slammed into the Japanese artillery positions several kilometers away as the covered fire extended.

Helicopters also took to the air, flying above the shells to the smoke-filled area, ready to block the ground there, replace the infantry, and provide protection for the tanks.

"Hound report, approaching the area of potentiation."

"Stop shelling!!"

As the information in the headsets was exchanged, the roaring cannons stopped, and the shaking of the ground ended, and there were only smoking areas and potholed soft earth.

Inside the tank, the periscope saw a mess everywhere, and in some places there were faint traces of concrete.

"Numbers one to six. High-explosive shells are loaded, revealing the position of cement in the middle of the bunker in front of the target. ”

The commander of the team ordered.

Immediately, the muzzles of the tanks were aimed at the target. The position that was more than a meter above the ground, revealing the faint concrete, and a few seconds later, the tom cannon rang out.

The explosion swept away the small amount of frozen soil, and when the dust cleared, a concrete wall about two meters in diameter appeared in the periscope.

"No. 1 to No. 6 armor-piercing bullets reloaded! The rest of the precautions! ”

The captain of the team calmly ordered.

More than two dozen tanks formed a circle, and the anti-aircraft machine guns and heavy machine guns on the vehicles were pointed in all directions. As long as the Japanese army dares to show their heads, Bibao will invite a devastating blow.

The helicopter is a hundred meters away from here, in the air. Vulcan cannons and heavy machine guns keep an eye on the tanks below, and they can tear them to shreds if a figure appears nearby.

The roaring explosions continued one after another, in the midst of the fires. Splashes of cement fragments everywhere. Whistling in the air, clanging on the tank.

A round of shelling, but did not blow up the cement bunker, obviously, the thickness should be more than one meter, Liu fired the shell, there was only a pit more than half a meter deep and more than one meter in diameter. However, the turtle pattern is dense, and it has lost the solidity of the cement bunker.

Wait for the smoke to clear. Seeing that it didn't explode, the commander was stunned and ordered again, "The second round of armor-piercing shell loading!" ”

Before the cannon could be fired, the Japanese seemed to understand their intentions, and the muzzles of the guns were suddenly exposed in the distant bunkers around them, and then the flames flickered, and one warhead dragged the tail straight into the tank.

In the roar, the tank also found the direction of the iron fist, and then the muzzle and machine gun were aimed there, and the dense rain of bullets began to return fire.

In the bunker, the casualties of the Japanese army were not heavy, but the ineffectiveness of the iron fist made them very helpless, and their hearts sank to the bottom when they saw the flames erupting on the tank.

Fortress artillery can't hit the approaching tanks, if they are allowed to bombard, no matter how thick the bunker is, they will not be able to block their shells, and sooner or later they will be blasted away, not to mention that the other side is obviously using armor-piercing shells, and they are new shells that they do not have, with high explosive power, not hard-hitting armor-piercing shells.

The iron fist and the gunfire stopped, and it didn't take even a minute before and after, and then the fighters on the helicopter saw the funnels appear one by one in front of the bunkers, like quicksand in bunkers.

"Look! Why do those places seem to be missing? ”

A fighter shouted from the open hatch pointing to a position dozens of meters away.

"Could it be that the Japanese bunker is leaking?"

Another soldier held the Vulcan cannon and said suspiciously.

As he spoke, suddenly, a black hand stretched out from the base of the funnel, and then the funnel expanded rapidly.

"It's the Japanese army who is coming out!!"

In the midst of the shouting, the muzzle of the soldier who saw the hand was raised, and with a buzz, the terrifying sound of the Vulcan cannon rang out, and the bullet casings rained down from the sky in the spray of fire.

As soon as the bullets flashed, they covered the vicinity of the funnel, and in the dust, blood splattered, and needless to say, the Japanese troops there were torn apart by the dense bullets.

"Watch the funnel below!!"

Shouts rang out from the helicopter's special channel, and then the fighters on the helicopter saw the craters that were collapsing rapidly, and then saw their heads coming out, and even worse, holding explosives bags in their hands.

"Sample! I still want to blow up the tank!! ”

A contemptuous muttering came from the helicopter's channel, then drowned out by the sudden buzz.

As the tongue of fire erupted, the dust below floated up one by one, and then the blood mist mixed with the dust floated into the air.

The tank matrix also saw something strange there, and the machine guns were pointed there, ready to fire at any time.

The Japanese were trying to climb out of the narrow exits, but the soil accumulation caused by the shelling filled in these reserved small openings, and in desperation, they quickly cut the soil into the tunnel, which formed a funnel-shaped shape on the ground.

But where have they seen the power of helicopters, before they can get out of the tunnel, they are torn apart by the dense rain of bullets, and they are blocked at the mouth of the tunnel.

They were holding explosives in their hands, and under the dense bullet penetration, the detonators were naturally exploded.

Boom!

One explosion after another engulfed hundreds of funnels in flames, accompanied by the screams of the Japanese soldiers who failed to climb out from behind. Not to mention that they had their own bombs buried the hole, and even the Japanese soldiers in the narrow passage were shocked to death.

The blast wave of the explosion set off waves of air that made it difficult to control the plane that began to circle and lower, and then, at the command of the handheld plane, the helicopter circled and ascended, avoiding these shock waves and the cement and stones that could fly.

Just a moment, the second round of shelling ended, and a hole the size of a bathtub appeared in the concrete wall a few dozen meters in front of the tank.

"Pay attention to protection, the tank retreats! Firefox One step forward! ”

The captain of the team gave orders one after another.

There are cannons in the tunnel, but there are shells in them, which will cause explosions if ignited, and the tanks are too close to each other, and people will not be killed, but they will be shocked to death, and even more shells will directly tear the tank apart.

The helicopters also received the order, and they all ascended, and then they all increased their horsepower, flew away into the air, and flew away to the side, and evacuated this airspace.

As the matrix dispersed, the tank orderly leaned towards a section of cover 100 meters behind, and then a Spitfire came out of the crowd, and after the tank withdrew dozens of meters, with a snort, a fire dragon rushed straight to the hole that exploded.

The fire dragon burrowed into the hole without waste, and the tank sprayed twice in a row, and the hole was in flames, so that it didn't even lose its head, and galloped backwards quickly.

As the flames erupted, the cave immediately became a sea of fire. More than 20 meters next to the location of the explosion was a cannon, a 150-year-old howitzer, at this time, it was wrapped in flames, burning fiercely.

At the entrance of the cave, the air was pumped inside, forming the effect of a blower, making the sea of fire inside burn more violently.

In the flames, piles of large cannonballs were also burning, and they were placed less than ten meters next to the cannons. Further in, a narrow aisle leading to the gun chamber of another cannon, no more than thirty or forty meters apart, where another cannon squatted.

The flames, with the sound of the wind and the whining sound, slammed into the tunnel with the second fire dragon of the Spitfire Tank, and swooped down the narrow passage to a gun chamber, and then wrapped the cannons there, as well as the piles of shells of a hundred pounds.

At both ends of the fire-breathing gun chamber, when the flames poured in and there was nowhere to vent, it was really like a fire dragon, filling the gun chambers on both sides with flames, wrapped in piles of cannonballs, burning fiercely, and the temperature in the gun chamber also rose suddenly.

In the artillery room, there was not a single Japanese soldier, they all hid in the anti-artillery room on the second floor, holding guns, guarding one after another insidiously designed interception points, waiting to blow up the bunker and give a devastating blow to the enemy who rushed in.

They all wore gas masks, they were not nervous at all, under the brainwashing of militarism, their fanaticism made them not timid, and their eyes behind the glass were even more bursting with the frenzy of drinking blood.

But they never expected that the advance army was not fighting for this place and destroying them, but to burn the artillery here, and they were already sitting on the volcano, waiting for the release of the critical point after the sudden compression.

The retreating tank quickly arrived at the bunker a hundred meters away, and was turning rapidly, and the tank in charge of Spitfire had not yet rushed to them, the earth suddenly trembled violently, followed by an even more violent uplift, and then, an earth-shattering loud noise came, and the world was suddenly quiet in everyone's ears.

The pilot on the helicopter only felt a light in his eyes, and at the same time he was blind, and his ears buzzed again. The helicopter, like a dead leaf, rolled in the raging air waves, lost control, and threw the four fighters in the cabin out of the plane without closing the hatch, rolling and being engulfed in flames.

A huge cement block was crushed and blown away by the shock wave, and with a bang, along with the helicopter, it turned into pieces, and then into dust.

On the ground, the shock wave swept through, and the tank and the Spitfire tank were heavy enough, and fortunately they were not overturned, but the violent shock caused the soldiers inside to erupt out of their lungs one after another, and they died in the tank, allowing the tank to be wrapped in flames, and then ignited a fire.

There were not many tanks that turned the corner, but fortunately the two Spitfires followed, but the drivers inside also lost consciousness in the earthquake, and let the tanks continue to run through the falling debris like flies until they hit the cover. (To be continued......)
