Chapter 533 Death, Arrival

The underground fortress is an emergency-built building.

It is cylindrical in shape and stands in the underground space. It occupies a large area with a diameter of more than 350 meters. The internal space is not large, only more than 20,000 square meters, and the thickness of the external metal wall is more than 150 meters.

The wall adopts a super-strong molecular order structure.

This structure does not increase the density of the material, but arranges the molecules in order, and then inserts a kind of creation particles with strong traction in the gap.

The creation particles firmly grasp the surrounding molecular structures with electrostatic force.

The shape of these molecular structures has changed from cubes to bricks, and they are like bricks, and the creation particles are cement between bricks.

This stable structure can withstand other attack methods except electromagnetic force attacks, and the demand for materials is not high, so it is widely used.

Through a 20-meter-high gate, everyone began to retreat back to the bunker.

The way to open and close the gate is to first increase the gap between the surrounding wall particles, and then decompose the gate into particles and temporarily put them into the gap between the wall particles.

In this way, the door does not need extra space to be installed. After all, the thickness of the entire wall is more than 150 meters. In order to ensure the overall strength, the door must also be 150 meters thick.

The open door is only temporary. The wall will slowly repel the particles of these doors and then return them to their original position.

"Hurry up!"

Yan Xia asked the soldiers to hurry up.

The federal people will start to advance after dealing with the arranged soldiers. Yan Xia believes that their speed will not be very slow.

At this time, they should send some robots to explore the surroundings.

These robots do not have any crystals, but a mechanical structure similar to the Stirling engine, which uses the alternation of hot and cold to provide mechanical power.

Their movement mode is like a clockwork car, rushing around.

These robots crawl on six legs and can ignore most of the terrain.

Their essential function is to clear mines and other induction traps.

If these robots are released in large numbers, the federal soldiers will advance very quickly, which is impossible to prevent.

Just as Yan Xia reminded, a bug-like thing rushed over here.

Yan Xia could not see him, and the others around him were also unable to see him.

But the sound of its mechanical mechanism could be heard approaching.

"Get out of the way!" Yan Xia shouted.

The soldiers outside were also panicking at this time.

Although this robot does not have any crystals, it has a simple biological trigger device. Generally speaking, other objects around it maintain a constant temperature, and only the temperature of the organism itself will be different from the surroundings.

As long as this temperature abnormality is detected, it will explode.

"Bang!!!"

Just three seconds after Yan Xia shouted, the explosion occurred.

The terrifying impact blew away all the soldiers around, and those who were closer were all minced meat at this time even if they were protected by mechas.

This bomb is a special anti-mecha bomb.

Most of its power comes from the shock wave of vibration.

The shock wave is transmitted through the compressed gas molecules inside the bomb. When the gas molecules come into contact with objects on a large scale, the special kinetic energy stored in the molecules will be transferred to the surface of the mecha.

Mechas can generally absorb quite strong kinetic energy, such as the physical impact caused by pure gunpowder, even a 1 million dense mecha can easily defend.

However, the kinetic energy stored in these molecules can instantly exceed the impact of 500 million dense explosives exploding at the same time, and it is densely packed in a very small area.

And it is transmitted to the inside of the mecha through a highly penetrating induced resonance mode.

The mecha itself is also a material, and the vibration of the molecules ejected by the bomb can cause the material of the mecha shell to resonate.

The explosion killed 4 people.

The remaining injured will recover with the help of the quark robot.

The explosion itself is not the main threat.

The real threat is that the enemy can know their location through the explosion.

When the location is determined, it is the release of weapons.

"Go in, go in!"

Everyone rushed into the bunker frantically. It was chaotic and panic.

Even Yan Xia could not stop the chaos from happening. Everyone has their own independent consciousness, and they all serve themselves.

The so-called discipline cannot achieve order when these people are individuals.

Fortunately, Yan Xia has other means.

Directly through his own permission, everyone's thoughts at this time have a slight change.

The chaotic situation suddenly became orderly.

The enemy will not give them a chance.

The information had been received by the enemy, and a new round of attacks came in an instant.

At this time, everyone who was still outside felt that their bodies were hit by something, and their entire bodies were instantly accelerated to a speed of more than 100 km/s and hit the wall of the bunker.

The surface of the bunker rippled like water, absorbing this energy.

And those who were hit had turned into meat paste.

Including Yan Xia.

"Captain!" People who had entered the bunker saw the information.

[Captain Yan Xia died! ]

Everyone felt cold in their hearts.

Yan Xia, who led them all the way, died just like that?

They couldn't believe it, but at this time they could only enter the bunker.

The door of the bunker was then closed.

Less than 3 minutes later, the roar of machinery came, and more and more robots arrived here, and then they kept moving forward against the wall of the bunker.

After all, they were just some mechanical robots with clockwork structures.

Following behind them were federal soldiers wearing mechas.

"The bunker is in front, legion commander!"

The legion commander is almost the highest military rank on E-star, and captains above him rarely enter E-star directly.

The people from the Federation who came to the underground battlefield were actually of this level.

More and more federal soldiers gathered in front of the bunker, and the number seemed to be close to 1,000.

On the battlefield of E-star, this is already a very large number of people.

Although it is easy for human civilization technology to produce clones to go to the battlefield, it is almost impossible to do so in a closed battlefield like E-star.

There is no production line for high-strength mechas or quark robots on E-star.

Even if clones are produced, they are at best low-level cannon fodder, and the threat they cause on the battlefield is limited.

And mechas and quark robots are almost equivalent to consumables on a battlefield of this level.

Too many weapons can damage mechas and quark robots.

Instead of doing this, it is better to directly transport people to E-star from the outside, which is very cost-effective.

Reeves, the commander of the federal army, asked everyone to start equipping defense and weapons on the spot.

"Is the upper passage broken?" he asked the people around him.

The other one was a staff officer.

He received information from other teams through a special vibration mode.

"It was blocked before we attacked."

The bunker is like a jar underground. There will be an elevator shaft connected to the ground above. At the same time, the elevator shaft also serves to transmit ground information to the entire bunker, and use the host above to control the bunker to escape upward.

The bunker is similar to a jar, but it is still a war machine. It can dig soil and move underground.

In order to prevent these situations, the federation has already cut off the bunker's retreat.

"That's it, now we have caught the turtle in the jar." The commander of the army said confidently.
