In order to ensure that the fortifications that the troops had occupied would not be recaptured by the Chinese troops, he still sent a large group of troops into the fortifications, preparing to use Qin Feng's trenches inside them for defense.

But he didn't know that his order had dug a huge grave for his troops.

In the central trench of the fortifications, there were scattered logs everywhere, which were originally wooden structures that had been used to build artillery shell defenses in the rear, but they had been torn down by Qin Feng when they were retreating.

But in the choking smoke and dust, the devil did not notice that there were always some dark wood chips under the trench, and the small black water flowing at the edge of the lower trench.

The Devil's troops stepped on logs to enter the trenches, where they could escape some of the cold, but there were grenades and explosive packs scattered throughout the trenches.

This caused the devils not to immediately light a fire to keep warm, but to tidy up the trenches, and some of the devil soldiers leaned on the back of the log-built fortifications, which were already only more than half a meter high, paying attention to the gradually brightening earth in the distance.

A gust of wind blew, and all the smoke and fog in the distance dissipated, and at this time, the devils could see the trench where the Chinese troops were located a hundred meters away, but the scene they saw did not understand what they saw.

The attack of the devils at dawn was a failure, because they did not break into the trenches of the Chinese troops at all, but were frightened by the heavy fire of the opposing side.

But the scene now is indeed that the Chinese troops retreated in panic after seeing the trenches where the devils had been stationed, as if they saw some kind of terrifying danger slowly approaching.

The devils were very puzzled, could it be because the strength of their own side was too strong, so the Chinese troops were terrified?

Ushijima Sadao brought more than a thousand soldiers to this fortification that Qin Feng used before, and he couldn't help but sigh when he looked at the dense log structure here and the buildings made of cement, stone and wood on the fortifications.

No wonder their violent crowding and the blasting of the explosives packs were so difficult, for the structure was divided into concrete stones, and at the end there was a thick layer of logs.

Such a log can withstand a very strong impact, and it also has the function of setting fire.

After all, the flames caused by artillery explosions could hardly ignite logs with concrete layers, so these fortifications were difficult to destroy.

But all of a sudden, he saw a group of soldiers who had brought dry firewood from somewhere, apparently because of the cold weather, so they were ready to warm themselves in the trenches.

But Ushijima Sadao was not faintly uneasy, he didn't know why this was happening, generally speaking, there was nothing wrong with lighting a fire in the trenches to keep warm?

And he looked at the Chinese troops who were desperately retreating, and he always felt that there was something strange, and suddenly his eyes widened, and he glanced at his feet, and then at the soldiers who had lit the matches and were ready to start the fire.

Suddenly, his face changed dramatically and he couldn't help but scream in horror, but it was already too late.

Ushijima Sadao looked frightened and shouted at the ghost soldiers who were lighting the bonfire.

However, when he shouted, the campfire had already been lit by the devil's soldiers.

The Chinese troops, who also saw the firelight, frantically wanted to retreat, retreating to the trench behind the pillbox a hundred meters away, they retreated in such a hurry that they almost ignored the devil troops behind them.

This made Ushijima Sadao immediately guess that the Chinese troops must have hidden some conspiracy in this fortification, and as the cold wind blew, the thick scorching smell also lessened a lot, and only then did he smell the smell of diesel fuel coming from under his feet.

Before that, the smell of diesel fuel was obscured by the smoke of various burning fires in the distance above, so that the devil did not smell it immediately.

However, as the cold wind from above and the weakening of those fires gradually became discovered, this discovery immediately made Ushijima Sadao understand what the conspiracy of the Huaxia people was.

From ancient times to the present, fire is one of the most feared existences of human beings, and many devils who know something about Chinese culture know how to burn the Chibi Fire Ox Formation and so on.

And Qin Feng likes to use this method to deal with devils, especially now that he has kerosene, diesel and other fuels, so that Qin Feng has sufficient resources to implement these methods.

In order to confuse the devil, he deliberately burned a series of fires before retreating, and the fires were covered with a layer of animal fur to hide the smell of oil and gas in the first layer of fortifications.

And because the devils had just rushed into the defensive positions of the Chinese troops, they did not find the fuel flowing under the scattered logs in the trenches.

Coupled with a layer of wood chips, the fuel will first mix with the wood chips on the ground, and when the wood chips have reached their peak absorption capacity, they will emit a strong odor.

However, by the time the devil can smell the smell of oil and gas, it will be too late.

For example, now, even if the devil doesn't light the bonfire himself, Qin Feng will also project flames on the first layer of trenches, and it only takes a little flame to rush in, and the devil's troops will fall into an endless sea of fire.

And once it burns, the flame will not be extinguished for a few hours, and then the devil's attack will be blocked by them for a long time, and at the same time it will cause huge pressure on the psychology of the devil soldiers.

War is to test the country's material capacity, but also to test the courage and faith of the soldiers on the battlefield, continuous long battles, the devil has left countless corpses on this battlefield, which itself has made the devil's soldiers fearful.

Coupled with such a terrifying fire, if the devil's troops want to continue attacking, they will inevitably have a lot of courage, which is a huge benefit to Qin Feng and their defense, which can reduce their pressure.

The devil's soldiers pressed the border, although the continuous resistance was very smooth, and the huge casualties of the devils also greatly increased the confidence of the soldiers under his command, but the continuous high-intensity battles, the soldiers on their side are now exhausted.

Especially those machine gun shooters, the continuous shooting of a day and a night has made many soldiers sore, which is very unfavorable for the subsequent battle, if there is such a few hours of rest time, it is very necessary for the soldiers.

And the devil's troops now have no idea what is going on inside the fortifications, because the high fortification wall is in front of them, and they only see the troops of their own side rushing in.

The rest of the devil troops are also rapidly assembling and preparing to continue to enter, wanting to occupy a firmly captured position so that they can continue to attack.
