But history is history. Zhang Chi has to change history when he reaches this time and space, especially since he cannot let the history of "paying a heavy price and not being able to seize the train fortress" happen again... The troops attacking the railway station are the New Regiment. If this history happens again, it means that the New Regiment will have to suffer heavy casualties, and it is very likely that Zhang Chi himself will include.

But it is one thing to refuse to admit defeat. Zhang Chi lost his mind when facing such a steel defense line that cannot be penetrated by guns and cannons.

Just when Zhang Chi was worried, he saw several soldiers on the battlefield who had no time to retreat were digging fortifications... This was what Sun Brambled's training was. The American instructor said: "If you didn't have time to retreat when you failed the offense, then you should stop and take out any tools you can use to do one thing, dig fortifications!"

This theory naturally has its own reason, because the offensive failure did not withdraw, and more often happened between the defense lines of the two armies. Everyone knows that this area is the place with the most bullets and the most guns. If you run back desperately at this time, the chance of survival is slim.

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

At this time, Zhang Chi discovered a problem: the vast majority of the Japanese troops in the "Train Fortress" used direct firepower... This is determined by the particularity of the "Train Fortress". The Japanese troops' firepower configurations on the train defense line are divided into upper, middle, lower, middle and lower layers, upper and lower layers, upper and lower layers, and the top of the head is covered. The curved firepower, such as mortar grenades, cannot be used at all or it is difficult to use here... If you accidentally hit the head, you will blow yourself.

Only the upper level can use curved firepower, but the Japanese army has very few troops in the upper level. The reason is that the Chinese team has very strong firepower. Once the Japanese army is exposed in the upper level, it will soon attract a piece of shells.

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

Zhang Chi soon thought, if those warriors could do that, why can't other warriors?!

So Zhang Chi said to Wang Mazi: "The group seat... we may be able to dig it over!"

"Dig it?" Wang Mazi couldn't help but wonder when he heard this.

This tactic is actually very simple. It is to dig the trenches layer by layer in the direction of the Japanese army. Since most of the Japanese army can only use direct firepower, it has no choice but to use the soldiers in the trenches. If there is any danger, it is that the Japanese army can throw grenades at the trenches that are too close to them.

But the problem is that the Japanese army hiding behind the sandbag and having a cover on the top cannot drop the grenade too far, so the grenades of the Chinese team can blow the Japanese army first, and the Japanese grenades cannot blow the Chinese team.

The war really developed as Zhang Chi expected.

The one who carried out this mission was a company of fellow villagers. They didn't even bring rifles or bullets, and they just dug the trenches with a engineer shovel.

The reason why they did not carry rifles and bullets was, on the one hand, because there was a firepower team to provide cover for them and the Japanese army in the "train line of defense" was basically impossible to launch a charge. If the charge was launched, it would still be what the Chinese team hoped.

On the other hand, it was because the trenches they were asked to dig were only allowed to pass by one person... This was for convenience and speed, and a narrow trenches like this would undoubtedly increase a lot of difficulties and inconvenience if they carried rifles. So they simply left the rifles, with only a few platoon leaders carrying Thomson on their backs to prevent them from being 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 in parallel to the Japanese defense line... The vertical trench was to move forward, and horizontally in order to be able to expand its forces.

This method looks stupid and the progress is not fast... Although the land that has just passed the rainy season is not difficult to dig, since it can only hide in the trenches to dig in one direction at the same time and in one direction, it is almost like a snail climbing forward.

But this is undoubtedly effective, which can be seen from the reaction of the Japanese army in the "train line of defense".

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

"Are the Chinese worried that we will charge back?" Looking at these, Colonel Kaitian couldn't help laughing: "They wouldn't be so stupid that they thought we would give up these lines of defense and rush out!"

The Japanese troops around also laughed. They were obviously proud of such solid fortifications they built.

But it didn't take long for them to laugh because they saw the Chinese trenches approaching them layer by layer...

Colonel Feitian quickly realized what the Zhongzhe was doing, and couldn't help but curse: "Bastard. The Chinese are trying to dig the trenches in front of us!"

"You can't let them succeed!" The next second Colonel Feitian ordered: "Hurry up, blow them back!"

But this order was obviously wrong. When the Japanese artillery and grenade launcher had just fired more than ten shells into the trenches, the Chinese artillery that had been prepared had poured fire into the direction of the Japanese army.

So Feitian was soon stunned... He couldn't shoot a gun, and he would be suppressed by the Zhongxun Team again. He seemed to be the only thing he could do, that was to watch the trench dig forward layer by layer, and the Zhongxun people also got closer and closer.

In the end, there was no other way, Fei Tian could only report this question to the top. But the answer he got was: "What is your problem? The soldiers from other directions are still fighting with the China Team, but you are anxious because the Chinese are digging trenches in front of you!"

After saying this, there is no sound in Feitian... This may be really not worth mentioning. But it is indeed worth mentioning, because it will undoubtedly pose a threat to the "train fortress".

As for what level of threat this would be... Fei Tian didn't know. He only knew that this was definitely not a good thing.

The trenches were dug until the sky was getting darker.

But the Chinese team still refused to stop... In fact, it was not that they refused, but that they did not dare to stop.

Because Zhang Chi knew that the Japanese were very good at night battles, he was worried that the Japanese army would penetrate and destroy the trenches in the night, which would make all the efforts of the day go by wasted.

So more than a dozen searchlights illuminated the Japanese defense line, illuminating the entire area as sad as daytime. Cannons and machine guns were also ready to shoot. Any sound on the ground would be strafed and bombed without exception.

At ten o'clock in the evening, the trenches finally dug up to a location that was only about forty meters away from the Japanese defense line.
