Our great China spans the multiverse

Defense Line 247, Yinshan Mountain Front.

The 48th, 49th, 7th Group Armies, 153rd and 156th Combined Divisions, as well as the original troops stationed here, in the remote command post, many commanders and combat personnel frowned and looked at the map of the entire front in front of them, and were silent for a long time.

on the map,

The mountains are densely built with various bunkers, and trenches are lined up so that the entire mountain range can be hollowed out.

The most important thing is,

According to reports from the front, a large number of mimic creatures are gathering in the narrow area in front of the defense line!

"Looking at the situation, the other party is going to fight us."

"On the 247 defense line, something was wrong, very wrong. Last time on the extended defense line, the opponent was also prepared in this way. When we were changing defense, they hit the line hard with one blow, forcing us to retreat."

"It's like they can predict the future!"

"We must make the defense line perfect and not let them have any opportunities to take advantage of it!"

"..."

The silence was broken, and all the commanders and soldiers looked angry.

Faced with these damn mimic creatures,

The human army is not invincible!

But these bastards, as if they have a God's perspective, can accurately grasp the flaws in their offensive every time.

Fighting them is like playing hide and seek.

Ambush and counter-ambush, encirclement and counter-encirclement, ambush and ambush...

In the end, they were so confused that they were suddenly attacked by mimic troops who appeared out of nowhere.

And now,

A narrow opening in position 247,

It was the key to their victory.

According to the mountain topography, this place has an unobstructed view, and it is impossible for the mimic creatures to ambush!

Also because of this,

When all the commanders and combatants saw the increasing number of mimic creatures, they also knew,

The opponent should have realized this, so they were preparing for a positional offensive and defensive battle.

Since ancient times, offensive and defensive positions have been

That is a pure meat grinding ground!

A solemn atmosphere spread in the command room until a commander took a deep breath, stood up suddenly, and said angrily:

"He's such a jerk,"

"Dig back another foot on the slope and hide the artillery for me. This time we must not let the mimic sneak attack the heavy firepower troops!"

"Blow these turtles to death!"

In the headquarters, several group armies are reinforcing their defense lines.

And at the foot of Yinshan Mountain,

In the trench, Wang Chongshan, one of the soldiers on guard at No. 6 of the 33 Highlands, looked at the narrow mouth in front of him warily, always feeling a little uneasy.

The mimic swoops to the ground,

Such a large number exceeds tens of thousands, and they are all densely packed.

But in the field of vision, there are only a few mimics here and there, which is very wrong.

"Chongshan, be careful and don't get distracted!"

Just as the soldier was thinking about it, the health worker passing by patted him on the shoulder and asked:

"What are you thinking about?"

"Something doesn't feel right. It's too quiet across the street."

Wang Chongshan concentrated. He had fought against mimic creatures on the outer defensive line and was an experienced veteran.

It is precisely because of this that

He didn't think the Mimics would really arrange their troops like this to fight a so-called positional battle with them.

In the extension direction,

That group of ghosts, those flanking troops that ambush them, were made by grandma out of the soil. It was obvious that those bastards buried themselves in the soil, knowing that they were going to pass by here.

Wait, bury yourself in the ground and ambush?

"Old Xing, do you think it's possible? Mimicry is secretly digging tunnels, preparing to ambush our defense line directly from below. Just like in the flanking ambush of Extension 224, they emerged from the soil!"

Wang Chongshan stared suddenly, and a flash of light suddenly flashed in his mind.

It's really possible!

Although this is a method that Mimic has never shown in the five years since the war with Mimic,

But this is definitely a reasonable guess.

Because they have the ability to bury themselves in the soil,

Wouldn’t it be reasonable to expand a bit and dig a hole?

"... Your idea is very reasonable. Didn't the squad leader ask us front-line soldiers to show their subjective initiative? This is your subjective initiative. I will find someone to replace you immediately. You go and tell the instructor your guess."

The night watchman who was also at Gate 6 carefully observed the outside of the defense line. After hearing Wang Chongshan's speculation, he turned on the photoelectric lock and nodded fiercely towards him.

"good!"

Wang Chongshan also felt that it made sense and nodded.

Soon, people who were keeping watch for him were arranged to come over.

And he went to find the old squad leader of their team in person.

…

"Uuuuuu——"

At night, the piercing roar of jet fighter engines sounded, and the headlights flashed out, illuminating the area in front of the entire front.

The modified unmanned model Qi Ye suddenly flew over at an ultra-low altitude.

Under the silver-white fuselage,

Mounted is a circular sky pot that greatly affects the aerodynamic layout.

Of course, Master Qi doesn't care about this influence.

Anyway, it is an unmanned model used for consumption.

This is a device that can emit high-power microwaves. This kind of microwaves will bounce off the ground and be processed by the processor, which can have a rough underground impact.

This technology is also used in archaeology. Archaeologists dare not dig out the underground palace of the emperor due to protection issues, so some use this technology to get a glimpse of what the underground palace looked like.

The silver fighter plane just touched the sky above the mimic creature.

In the light,

a mimic creature, like a cannonball, was ejected from the ground, ruthlessly cutting off the fighter plane's path.

"Boom!"

The Seventh Master, who was flying at an even lower altitude than the ultra-low altitude, instantly turned into a ball of fire and crashed at the foot of the mountain.

In the back,

the data supervision center had been connected to the command post,

and the information officer was sweating as he looked at the data sent back by the Seventh Master.

"How is it?"

The commander and fighter stood aside, frowning and asking.

Just now,

the old soldier at the No. 6 entrance of the 224 position, Wang Chongshan, who had faced a mimic ambush on the extended front, proposed to the squad leader the possibility of "mimic digging tunnels and raids".

When the intelligence was passed to him,

he attached great importance to it and immediately arranged for the drone to go forward for detection.

Now, it's time to get the results!

"The computer is summarizing, the resolution is 90%, the situation is not good."

The information officer's forehead was covered with cold sweat, he saw something.

"There is an abnormal echo underground in front of the position, the computer is describing it in detail, 100%, it's out!"

The information officer quickly took off, called up the image, saw the content, widened his eyes, and hurriedly said in surprise:

"There is a tunnel, microwave detection shows that the tunnel has been dug less than 200 meters in front of the battle line!"

"It's bad!"

The commander stared and immediately ordered:

"Pass the order, everyone be alert, the other side may launch a surprise attack tonight!"

"Send long-range fire, who cares, bomb him!"

With an angry shout,

the commander's back was sweating,

Fortunately, it was discovered in advance, about 200 meters, there is still a buffer,

If it was really dug under the feet, it would be a mess!
