"The Japanese are about to start the attack and order Huang Hu to prepare for anti-aircraft bombardment. If the Japanese attacking troops are not seen, they must not come out of the anti-aircraft cave!" Zhou Cheng said with a serious order.

A minute later, the whistle of shells passing through the sky began to sound over the battlefield.

Four mountain cannons and two infantry cannons roared first, and the shells hit the trenches accurately and exploded, exploding a large amount of soil and logs, and the rolling smoke also rose from the blasting point.

"Boom boom boom..."

A series of more dense explosions then rang out on the front line, which was the Japanese mortar squadron joining the battle.

In less than a minute, the front line of positions was blown up and dust was filled with smoke, and thick smoke was everywhere, so it was impossible to see the situation inside the positions clearly.

Nearly two hundred Japanese soldiers stood up from the ground immediately. They wanted to approach the national rescue army's position as much as possible under the cover of artillery fire, shorten the attack distance, and once the artillery fire stopped, they could rush to the opponent's position in the shortest time...

When there were more than 100 meters away from the front line, the squadron leader raised his hand and ordered the troops to stop.

Because it is too dangerous to move forward, and it is likely to be accidentally injured by the shells fired by their own artillery.

Some people may say that the Japanese artillery is very good, and artillery can basically hit wherever it is pointed, and the shells fired cannot be more than a hundred meters away.

The truth is indeed the case: if you shoot at close range and only fire one or two shells at the target, the Japanese gunner can indeed achieve a hit rate of more than 70%, which means you will hit wherever you are, and the error of the bounce point will not exceed five meters.

But what the Japanese in front of him was covered with artillery fire, and one cannon fired more than twenty shells at will.

All the artillery were placed in the fortifications dug in advance, and the ground was soil, not cement. The strong recoil caused the artillery to move or sink every time it was fired...

Even if the muzzle is only one or two centimeters away from each other, after amplifying the distance by one or two thousand times, the bounce point will be 40 or 50 meters away.

If the muzzle is deflected up and down by one or two centimeters, the range of the artillery will immediately increase or decrease by hundreds of meters.

After the shelling began, almost all the shells that were fired at the beginning hit near the trenches.

Halfway through the shelling, the range of the bounce point began to expand, and many shells fell forty or fifty meters away from the trench.

When the shelling was about to end, the range of the bullet point was even larger. A mountain cannon shell landed directly ten meters in front of the attacking troops. If the attacking troops were not all lying on the ground, someone would definitely be injured.

Suddenly, the bullet point of the shell began to move toward the back of the defense line on a large scale. The squadron leader who was attacking with the team immediately pulled out his command knife and waved his order forward: "The artillery fire has begun to extend, machine gun covers, let's go out..."

"Dongdongdongdong...dakdada..."

Heavy machine guns and light machine guns joined the battle at the same time. The dense rain of bullets passed over everyone's heads and crashed head-on towards the first blocking position of the National Salvation Army.

More than a hundred Japanese soldiers immediately got up from the ground, bent over, held guns, stared at the front with a vigilant look on their faces, and ran quickly.

There was no movement on the blocking position. Either the National Salvation Army had not yet reacted to the artillery fire just now, or they suffered heavy casualties from the artillery bombardment just now and temporarily lost their combat effectiveness.

No matter which reason, the Japanese must seize this opportunity to further approach the blocking position and shorten the assault distance after the National Salvation Army began to block.

"boom……"

An explosion rang out in the middle of the attacking troops, and black smoke rose on the ground at the same time.

The squadron leader quickly reacted, but did not take it seriously: "It's a mine, don't worry about it, everyone continue to attack!"

When there were more than 80 meters of blocking positions, three consecutive explosions sounded in the squadron leader's ears at the same time.

He still didn't react much, and waved his command knife to order the troops to continue attacking forward.

He had encountered this blocking method before. The enemy buried mines in front of the camp, slowed the assault speed of the attacking troops through the mines, consumed the attacking troops' strength, and bought time for the blocking troops to prepare for the pre-war preparations.

Although the mines are very powerful, their subordinates are all lined up to attack in scattered lines, and the formation is very scattered. Under normal circumstances, one mine can kill at most two imperial troops, and this casualty will not affect the overall situation.

"Boom...boom..."

More and more landmines began to explode, and the attacking troops became closer and closer to the blocking position.

At this time, there was no movement in the blocking position ahead.

The squadron leader quickly raised his command knife and prepared to order the troops to launch the final assault...

At this moment, the deputy captain who was following him suddenly realized something was wrong: "Sir, there seems to be something wrong with the mine we encountered..."

"The anti-destructive radius is at least twice as large as ordinary landmines. The Imperial Army ten meters away can be injured by the bomb. Our formation is already scattered enough. One landmine still kills and injures four or five of us..."

The squadron leader didn't believe it very much.

The explosions kept ringing in my ears were exactly the same as the mine explosions I had heard before. The power of the explosion should be the same. How could it be so much?

But out of caution, he still glanced around...

His eyes, which were still confident just now, immediately widened, showing a shocked expression of disbelief.

The orderly offensive formation around him had been broken by landmines, and a full infantry squadron had at least one squadron.

You should know: until now, the National Salvation Army on the blocking position has not taken action, and there are still sixty or seventy meters away to attack...

"Da da da da...b...b...b..."

The squadron leader was stunned and the blocking position, which was still covered by gunfire, finally a gunshot came from the blocking position, including machine guns and rifles.

The offensive troops were caught off guard and were knocked down seven or eight people in an instant.

The remaining soldiers quickly squat down or lay down, raised their rifles and started to counterattack, shooting and attacking...

"Boom...boom..."

Two explosions sounded in the squadron leader's ear, and someone must have stepped on the landmine again. This time he saw it very clearly.

The moment the black smoke rose from the ground, all the imperial troops within ten meters around the explosion site were blown up, either dead or injured.

The squadron leader exclaimed in surprise: "What's going on? How could the landmines of the National Salvation Army have such great power?"

No one answered his question, and his subordinates couldn't understand it just like him.

"Boom..." Several explosions sounded at the blocking position of the National Salvation Army. Grenadiers joined the battle in time, destroying the machine gun fire points just exposed by the National Salvation Army, and reducing the combat pressure of the offensive troops.

After two rounds, it worked because the sound of machine gun strafing on the blocking position became obviously intermittent.

This is a good opportunity to capture the position of the National Savior Army. The squadron leader decided to temporarily put down the mines, seize this excellent opportunity, and rush forward thirty meters so that the troops can use grenades to attack the National Savior Army in the trenches.

He raised his command knife again and ordered at the top of his throat: "We knocked off the firepower point of the National Saving Army... Continue to assault..."

"The machine gun and grenade launcher provide fire cover, the rifleman prepares the grenade, captures the positions of the National Rescue Army, and kills..."

"Dongdongdongdong..."

The sound of heavy machine guns fired broke the squadron leader's dream. Two heavy machine guns suddenly appeared on both sides of the position, and the bullets fired formed cross fire, and were slaughtering his subordinates to the fullest.

"Boom..." The mines also ran over to add fuel to the fire, and seven or eight more imperial soldiers fell from the two groups of black smoke.

Seeing that the remaining soldiers were all pressing on the ground and unable to continue moving forward, the squadron leader was like burning his butt and was very anxious to order.

"Grouter launcher shooting, knock off the heavy machine gun in front immediately."

"Boom..." Grenades hit one after another and exploded next to the heavy machine gun, but the harsh gunshots never stopped. Flying bullets continued to fly against the ground, shooting at their subordinates.

The squadron leader became more and more anxious: "The position of the National Salvation Army must be hidden in the castle, and only mountain cannons can destroy it. Immediately ask the commander for artillery support, and the National Salvation Army's machine gun castle appeared!"

The brigade commander kept staring at the offensive battlefield. As soon as the two machine gun castles appeared, they ordered the mountain artillery squadron to destroy it, without waiting for the offensive troops to seek help.

"Boom boom boom..."

The thunder-like explosion quickly rang around the castle, and the heavy machine gun that had been ringing for several minutes finally stopped.

The squadron leader subconsciously believed that the castle had been destroyed by mountain cannons, so he ordered the troops to attack forward again.

"Dongdongdongdong..."

As soon as they got up from the ground and rushed forward less than ten meters, the heavy machine gun fire sounded again, which made them feel scared.

The squadron leader was about to be crazy.

Before contacting the National Salvation Army, the attacking troops were blown away by the opponent's mysterious landmines.

After contact, the National Salvation Army had a cranking machine gun and heavy machine gun, and fired at itself one after another. In addition, the mysterious landmines added fuel to the fire. On the attack road for only 20 or 30 meters, he lost more than a team.

After glanced around, he found in despair that there were less than fifty subordinates around him, and most of the soldiers had a trace of inexplicable panic flashing on their faces.

They were all frightened by the endless means of the national rescue army, and they didn't know what kind of bizarre blockage they would encounter if they continued to attack.

On the offensive position, the brigade commander was also very angry.

He couldn't understand why heavy machine guns that had been destroyed by mountain cannons could continue to fire, and block the attacking troops if they took action.

What he couldn't accept the most was that under the attack of various means by the National Salvation Army, the offensive troops had been reduced from one infantry squadron to less than one small team.

If the National Salvation Army no longer uses other means in the subsequent battle, and the offensive troops want to take down the blocking position, they will be attacked by at least one round of grenade rain on the opponent, the casualties of twenty or thirty people will definitely be indispensable.

This means that the offensive troops will have little left to the position of the National Salvation Army and have no strength to truly occupy it.

In this case, it would be better to withdraw dozens of soldiers left on the battlefield, so as not to die meaninglessly.

With anger, he ordered: "The mountain cannon squadron continues to shoot, and this time he will knock off the opponent's heavy machine gun fire point for me no matter what."

"The mortars are also fired, and then the national rescue army blocks the position of the blocking force and covers the attacking troops to retreat. We lost the first round of attack, and there is no meaning to continue to fight, and it will waste troops."

For offensive troops, retreating is not as easy as imagined.

Although the firepower on the blocking position was suppressed, the mine array behind them was still there. If they wanted to evacuate from the battlefield, they had to pass through the minefield again.

As a result, more than a dozen soldiers were killed and injured.

In order to understand why the landmines buried by the National Salvation Army were so powerful, the squadron leader ran around a bullet crater and dragged several bodies back for inspection!
