With the firepower in these bunkers, there is a huge threat to the devil soldiers who break through the fortifications and rush in, and because the fortifications in front of them are relatively high, it is difficult for the devils to climb directly.

In that way, there are not many devil soldiers who can enter directly in the first wave, so there will be plenty of time to annihilate those devils who rush in.

Now it is to set a trap for the devils, weakening the offensive ability of the devils under layers of resistance, so that the devils cannot give full play to their strong military advantages, and at the same time, the devils have no heavy artillery, so these pillboxes have almost no threat.

This layer of defense is different from the previous one, because it has to defend thousands of meters of fortifications, so the troops are extremely scattered, but the second layer is only five or six hundred meters long, and there are so many pillboxes with a relatively wide line of sight to attack, it should be more difficult to break through than fortifications.

In such a place, light and heavy machine guns in the rear of the devils could not effectively support.

The defending troops only need to deal with the devil troops rushing in in the trenches, and even if they lose the trenches in front of them, the trenches in the rear are only more than 100 meters away from the devils' army fortifications.

At such a distance, the AK-47 submachine gun is capable of exerting a powerful striking force.

And Qin Feng had already left a lot of gifts for the devils in the trenches below the fortifications, and the devils' troops encountered a fierce blow after attacking the fortifications.

Qin Feng's troops used those original trenches to engage in positional warfare with them at the first time, so Qin Feng had already taken into account all the possible actions of the devils.

The so-called clever calculation, in fact, is to make an accurate guess of the enemy's psychology, what the enemy will make in a certain situation, what judgments and choices the enemy will make, these are all things that a good commander should think about, and the simple thing is to empathize.

Sure enough, just a few minutes after retreating, the devil keenly discovered that the Chinese troops in the front fortifications had retreated.

For a moment they thought that the Chinese troops had been frightened by their onslaught, so they abandoned such a strong fortification.

After all, in the eyes of the devils, even if they can blow up these fortifications, it will take a bloody battle to completely capture such fortifications.

And they know the combat effectiveness of the Chinese troops, and they are ready to fight bloody battles in the trenches and annihilate or crush the Chinese troops with their own bayonets.

But the Chinese troops withdrew on their own, which was a pie-in-the-sky thing for the devils, so the commander of the devils did not hesitate and immediately commanded the troops to rush forward.

Poof! A ghost soldier rushed in from the low part about four or five meters wide, and the moment he rushed in, the devil soldier immediately fell to the ground.

They were also very worried about whether they would be attacked by the Chinese troops when they rushed in, but he lay on the ground for a while but did not hear the gunshots, and it was clear that the Chinese troops were not attacking him.

The devil soldiers couldn't help but raise their heads, the rear of the fortifications was burning everywhere with piles of flames, and there were still some flames in the distance that were emitting smoke, in the eyes of the devils, this must be the result of their artillery, and the Chinese troops had lost their combat effectiveness under the bombardment of their artillery.

"Yeongxi, the people of China have collapsed, rush!" The devil soldiers who rushed in showed a look of ecstasy on their faces, this group of Chinese troops had already blocked their attacks so many times here, but they didn't expect to collapse at this time.

In their opinion, such a strong fortification is not defended by a single soldier, then it can only be said that the Chinese army has lost its combat effectiveness.

......The front-line commander of the devil had a ecstatic face, immediately drew his saber and raised it high, and rushed towards the rear of the fortification with hundreds of devil soldiers, who wanted to follow and pursue, and strive to annihilate more Chinese troops.

The news of the breach of the Chinese fortifications ahead brought a smile to the faces of Yasu, the Chinese commanders of the troops, despite their superb command skills.

But after all, their own side has an absolute superiority in troops, which makes it impossible for the other side to compare with them no matter what intrigues and tricks they have.

"Continue to increase the number of troops, and it is best to take the opportunity to launch an attack on the second layer of fortifications of the Chinese and annihilate them in one fell swoop." Kang Tianfu's confidence was bursting.

In his opinion, the two regiments under his command had not breached the position for more than a day, and it took him less than a few hours of hard work, which satisfied his self-esteem, and he immediately made the decision to continue to expand the results.

However, when the second wave of the devils' attack force rushed in through the small concrete fortifications, suddenly there was a fierce shooting sound from behind the fortifications, which made all the devils slightly stunned.

Da Da Da ...... Sudden ......

A hundred-strong squad of devils charged forward with rifles, because of the fog in the early morning, as well as the smoke bombs and smoke from the fire that Qin Feng and they deliberately placed, the devils did not see the situation in front clearly.

When he rushed out of the twenty meters, a Chinese trench suddenly appeared more than ten meters away, and then he saw countless Chinese soldiers peeking their heads out of the trench, and then countless bullets pounced on him like locusts in the sky.

Poof...... Poof...... The sound of bullets hitting the flesh and the screams of devils came one after another, and a few hundred devils were swept to the ground like wheat by the dense bullets almost instantly.

And the troops in the rear of the devils were also taken aback by such a sudden attack, and the devils who had just rushed into the fortifications immediately bent down to prepare for defense, and at the moment they remembered the gunshots, they knew that it must be the Chinese troops who were still resisting.

"Baga, the people of China are still in the fortifications, immediately let the troops entering be cautious, and if the defensive fire of the people of China is too strong, immediately stabilize the position and reduce the intensity of the attack." Kang Tianfu's eyes were puzzled.

The fleeting sound of gunfire stopped Kang Tianfu, who was already preparing to step into the Chinese army fortifications, and at the same time had a strong sense of crisis in his heart.

At this time, he suddenly felt something strange, because the closer he got to the Chinese troops' fortifications, the more he felt that the Chinese troops were retreating too strangely.

Because the fortifications in front of them were not fatally damaged, it was difficult for their troops to destroy the fortifications in a short period of time, and the Chinese troops actually chose to retreat.

If the forces collapse, then it is impossible for the Chinese forces to still put up fierce resistance at the front, so it can only be said that the other side has a certain conspiracy.

At the same time, a hint of red glow had already appeared in the east of the sky, and the sky was already about to dawn, and there was no need to continue to risk the danger of attacking at such a time.

Instead, wait for the weather to brighten up before concentrating a large number of troops to strike at the Chinese troops in the rear.
