But history is history, and Zhang Chi came to this time and space to change history, especially since he couldn't let the history of "failing to capture the train fortress at a heavy price" happen again...... The troops attacking the train station were a new regiment, and if this history were to happen again, it would mean that the new regiment would have to pay heavy casualties, and that would probably include Zhang Chi himself.

But it's one thing not to admit defeat, and in the face of such a steel defense line that can't be penetrated by guns and can't be blown up, Zhang Slack has no idea for a while.

Just when Zhang Chi was at a loss, he saw that there were still several soldiers on the battlefield who had no time to retreat digging fortifications...... This was the content of the training at Sunbrabeng, and the American instructor said: "If you don't have time to retreat when the attack fails, then you should stop and take whatever tools you have at your disposal to do one thing, dig fortifications!" ”

This theory naturally has its own merits, because the failure of the offensive did not withdraw, and it happened more between the defensive lines of the two armies. Everyone knows that this area is the place where the most bullets, shells, and muzzles are the most faced, and if you run back desperately, the chances of survival are slim.

Therefore, the wisest choice is to build fortifications in place and hide yourself.

At this time, Zhang Chi discovered a problem: the vast majority of Japanese troops in the "Train Fortress" used direct firepower...... This is determined by the peculiarities of the "train fortress", the Japanese army's firepower configuration on the train defense line is divided into three layers: upper, middle and lower, the middle and lower layers are covered overhead, and curved firepower such as mortar grenadiers cannot be used here at all or is very difficult...... If you're not careful, you'll hit the top of your head and blow yourself up.

Only the upper echelons could use curved firepower, but the Japanese troops in the upper echelons were very small, because the Chinese army had very strong firepower, and once a Japanese army exposed its position in the upper echelons, it would quickly attract a field of shells.

This made the Japanese army powerless against the few soldiers who built fortifications on the battlefield, and could only watch them dig individual bunkers and hide in them.

Zhang Chi quickly thought, if those fighters could do that, why couldn't the other fighters?!

So Zhang Chi said to Wang Mazi: "Tuanzuo...... We might be able to dig it up! ”

"Dig up?" Hearing this, Wang Mazi couldn't help but be puzzled.

This tactic is actually very simple, that is, to dig the trenches layer by layer in the direction of the Japanese army. Since most of the Japanese could only use direct fire, they were helpless against the soldiers in the trenches, and if there was any danger, the Japanese could throw grenades at the trenches dug too close.

But the problem is that the Japanese soldiers hiding behind sandbags and with a cover on top of them are also unable to throw the grenade too far, so on the contrary, the grenades of the Chinese army can blow up the Japanese army first, and the grenades of the Japanese army cannot blow up the Chinese army.

The war really developed as Zhang Chi expected.

This task was carried out by a company of fellow villagers, who did not even carry rifles or bullets, but carried only a sapper shovel to dig the trenches.

The reason why they did not bring rifles and bullets was partly because they had a fire team to provide cover for them, and it was basically impossible for the Japanese troops in the "train line" to charge, and if they did, it would be what the Chinese army wanted.

On the other hand, because the trenches they were required to dig were for only one person to pass through...... This is for convenience and speed. And such a narrow trench would undoubtedly add a lot of difficulties and inconveniences if you carried a rifle, so the rifle was simply left behind, and only a few platoon commanders still carried Thomson on their backs in case they were unprepared.

The trend of this trench was to dig a section vertically in the direction of the Japanese army, and then dig a section horizontally parallel to the Japanese defense line...... The erection of the trench is for the purpose of moving forward, and the horizontal is for the purpose of being able to spread the troops.

It looks stupid and doesn't go fast...... Although the land just after the rainy season is not difficult to dig, it is almost like a snail crawling forward because it can only be done by hiding in the trenches and only one person can dig in one direction at the same time.

But this was undoubtedly effective, as can be seen from the reaction of the Japanese troops in the "train line".

At first, the Japanese army did not take this action of the Chinese army seriously. Some of them are even wondering what the Chinese soldiers are digging trenches for so far away?!

"Are the Chinese worried that we will charge back?" Looking at this, Hita Osa couldn't help laughing: "They won't be stupid enough to think that we will give up these defenses and rush out!" ”

The Japanese soldiers around them also burst into laughter, apparently proud of the fortifications they had built.

But it didn't take long for them to stop laughing, for they saw the Chinese trenches closing in on them......

Hida quickly realized what the Chinese soldiers were doing. I couldn't help but curse: "Bastard, the Chinese are going to dig the trenches in front of us!" ”

"We can't let them get away with it!" In the next second, Hida Dazuo ordered: "Quick, blow them back!" ”

But this order was clearly wrong, when the Japanese artillery and grenadier shooters had just fired more than a dozen shells into the trenches. The Chinese artillery, which had been prepared for a long time, poured a sea of fire in the direction of the Japanese army.

So Hitada was quickly dumbfounded...... If he can't shoot a gun, and if he can't shoot a gun, he will be suppressed by the Chinese army, and there seems to be only one thing he can do. That is to watch the trenches dig forward layer by layer, and the Chinese soldiers are getting closer and closer.

In the end, there was no choice, and Hitada could only report the problem to the top, but the answer he got was: "What kind of problem are you?" Our soldiers in other directions are still fighting hand-to-hand with the Chinese army, and you are anxious because the Chinese are digging trenches in front of you! ”

As soon as he said this, there was no sound in the field...... This may not be worth mentioning, but it is certainly worth mentioning, because it will undoubtedly pose a threat to the "train fortress".

As for what level of threat this would be...... Hida didn't know, he just knew that it was definitely not a good thing.

The trenches were dug until it was getting dark.

But the Chinese army still refuses to stop...... In fact, it's not that he refuses, but he doesn't dare to stop.

Because Zhang Chi knew that the Japanese were very good at night fighting, he was worried that the Japanese army would take advantage of the night to infiltrate and destroy the trenches, which would make the day's efforts undone.

As a result, more than a dozen searchlights shone on the Japanese defense line, illuminating the entire area as if it were daylight. Artillery and machine guns were also ready to fire, and any sound on the ground would be strafed and bombarded without exception.

At ten o'clock in the evening, the trenches were finally dug only a little more than 40 meters away from the Japanese defense line.

So it's time for hand-to-hand combat. (To be continued.) )
