In the human metal fortress, there is a huge passage about 5 kilometers away from the front.

On both sides of the passage are rows of automatic warning devices. It can be seen from the dense weapon jet tubes on these devices. Its powerful power is no worse than the heavy machine guns on the front protective wall.

In such a 200-meter-long passage less than 10 meters wide, once these weapons are powerful, the consequences will be self-evident.

At the end of the passage is a metal door. It is now tightly closed.

More than 1 meter away from the door, red lights are crisscrossing, forming a huge net. It is now during the day. Because the light is too strong, if you don't observe carefully, these laser nets will be easily ignored.

And the location behind the metal door is in the mountain.

The one with such a close defense is obviously the outpost command post of human beings on this planet.

Major Clarkins was staying inside at this moment.

It can be seen from the expression on his face that this always serious officer also seemed a little anxious and uneasy at this moment.

Behind Krakins stood three rows of humans in military uniforms.

These were all officers from the Federation, from the lowest corporal to the lieutenant.

In the federal intelligence, there shouldn't be anything on this planet. In fact, when Major Krakins first came to this star system, he carefully scanned it.

Even after establishing the outpost, he still did not completely feel relieved. It was not until the drone's appearance that finally made him feel a bad feeling.

But this bad thing comes so quickly.

The power of the Arachi creatures is completely beyond the expectations of these humans.

Although the federal government already has information about these two creatures, it is not until people are in contact with these creatures that they appear. The creatures in front of them are not as described in the data.

No one can tell him that the creatures that spray acids even sprayed their ejaculation ranges beyond the weapons in the hands of ordinary soldiers. They are clear about the gravity of this planet.

Even though the soldiers were wearing combat armor, their movement was still much slower than those on other planets. Not only that, the huge gravity factor also limits the range of various material weapons.

And these material weapons are the ones that can really exert huge power on the battlefield.

Also, the bravery of the puppies also left a deep impression on humans.

They still remember the scene of thousands of puppies climbing over the city walls. At that time, not only Major Clakins, but also the humans in the outpost were sweating coldly.

"When will the two new production lines come?" Krakins suddenly said to Lena standing beside her after a while.

"Report to the Chief. The two production lines were shipped from Watson's letter. It is estimated that it will take nearly one day to get here." After hearing Major Crakins' order, Lena, who was thinking, immediately stood up straight. The two gangs said.

"It will take one more day? Why is it so slow? Haven't you given the specific information here to the Federation?" Major Clarkins seemed not very satisfied with Lena's answer.

"It has been reported. According to the information from the Federation, the production line transported this time was just developed by the Federation and has not been officially put into the army." Lena said.

"Oh. What's going on?" When Major Clarkins heard such words, the expression on his face immediately stretched out. He turned around to face Klena. He seemed to be very interested in this so-called newly released production line.

"This is the information. I'm just about to give it to you." Lena took out an electronic information board from her hand and handed it to Major Clarkins. She said: "This is the explanation and explanation of the two new production lines."

Major Clarkins did not open it immediately after taking the information board. He took out the card in his pocket. When he was about to use it, he suddenly stopped.

"You are now back to your post and stay alert. Although the other party has just retreated, there is no guarantee that they will not come again in a short period of time. And the most important thing is that you have also seen. These creatures are different from what you have experienced and learned in the past. Their cruelty is nature and there is no reason. Once the other party rushes in, you know the consequences. Think about the soldiers who are melted on the protective wall."

Maybe I saw the emotions the commander showed now, or maybe I thought of the tragic soldiers. After hearing this, all the officers' expressions turned pale.

Although these guys did not personally contact the Arachi creatures at that time, just what they saw and heard on the screen was enough to make them frightened.

After all, creatures that can even tear the metal baffles on the defensive wall are not something that human flesh and blood can withstand.

"Okay. Let's go back." Major Clarkins looked at the non-commissioned officers who were still staying. He shook his head and waved his hand gently. Then he swung the card on the console in front of him.

Then, as the light came, it shot into the room with the opening of the door.

The non-commissioned officers immediately walked out. But this time, their pace seemed a little messy.

Clarkins ignored these things. Although these non-commissioned officers were young, they were just assisting in command after all. The real battle was the clone soldiers who kept coming down from the production line.

After the officers completely went out, the door closed again. Only Crakins and Lena were left in the huge room.

Krakins immediately put the card on the information board. The red light on the board instantly changed to green.

All the information that was originally kept confidential will be displayed.

The entire hall then fell into silence.

Nearly half an hour later, Major Clarkins finally moved his eyes from the electronic board. He breathed a sigh of relief first and then asked Lena.

"Immediately place high-explosive electromagnetic induction lightning within 2 kilometers ahead of the outpost to 10 kilometers. Get close to the outpost within 1 kilometers. Build a defensive bunker."

"It's the sir." Lena replied immediately. Although Major Clarkins' expression is still serious now, it seems that there is less panic and more confidence than before.

It seems that the two production lines shipped by the Federation are still very powerful.

However, Lena was still a little confused about the orders Major Clarkins said. As an assistant, she looked younger. However, Lena had already followed Clarkins to participate in dozens of battles of all sizes. Therefore, she was very familiar with both of the things in the orders.

The high-explosion electromagnetic induction lightning was developed by the Federation three thousand years ago and has been used until today. Apart from the technological upgrade, its role has not changed.

Since it is called thunder, it must be something hidden below the surface. This kind of thunder has keen sensing ability. Whether it is biological or mechanical, as long as it walks above it, they can appear and quickly drill out of the surface. Then they bounce in the air about 3 meters and explode.

Unlike traditional thunder, the explosion of this kind of thunder does not make much noise. They rely on electromagnetics. For humans or organic organisms, this explosion will cause a series of reactions in the organisms, resulting in death of organisms and even the body cracks. For machinery or robots, this electromagnetic can instantly destroy the chip inside the machine, that is, the brain, and instantly turn it into a pile of scrap iron.

Moreover, this kind of lightning will not cause a chain reaction after the explosion. In other words, even if a lightning explodes, the other lightning around you will not be affected. What is hidden will still be hidden.

The advantage of this is that it can place a large amount of induction lightning within a small area. Half of it is used for special metaphysical effects.

Another device is often seen in the face-to-face wars of the federal army.

The defense bunker is hexagonally in the overall shape. You can observe six directions at the same time and can take care of the surrounding 360 degrees without any blind spots.

The height of the bunker can be adjusted according to the needs of the war. The size is not large. It is basically about 10 meters. 40 soldiers can be stationed in it at the same time. There can also be a large-power weapon above the bunker. This weapon can be changed according to the environment. It can be an ion cannon or a heavy machine gun, and even an anti-aircraft cannon.

The bunker is made of completely metal. It is thick enough to hit 40 points in total. Even the main gun of a powerful tank cannot destroy it with one shot.

Whether it is a thunder or a bunker, once it is used on the battlefield, the meaning it represents is to enter the defensive battle. The opponent's strength is strong.

And this is exactly why Lena is puzzled.

The war this morning was indeed fierce. To be honest, when Lena saw those fearful creatures fighting human soldiers from the screen. Even though she was used to seeing the bloody battlefield, she still couldn't help it. She almost vomited bile.

But fear is fear. However, this is just a fear of unknown creatures in terms of attack methods. It is not a fear of war. In fact, the number of opponents is not large. Although the war is fierce, the real damage caused is not much.

The wounds on the outer guardrail have long been repaired by repair robots. The deaths of cloned soldiers are less than 1,000. Such losses are almost negligible in previous wars.

Therefore, Lena still has great confidence in winning these creatures.

However, no matter how much I think about it, no matter how I am confused, as a soldier, Lena still knows her responsibilities. Therefore, she was stunned for a moment and then turned around and left.

With such an order, the entire outpost was once again busy.

All kinds of robots of all sizes immediately walked out of the guardrail and worked within a predetermined range according to the instructions.

The establishment of the defensive bunkers was still very fast. A large number of metal plates were transported directly from the production line to the point where they were quickly transported. Then immediately there were three to four machines more than 5 meters high. They walked up to them and assembled the metal plates and welded them together.

The robots who placed the thunder were a little slower. This was mainly due to the distance. The specific thunder was placed extremely quickly.

As a major, Clarkins's idea was different from that of Lena. The two production lines transported by the Federation were his expectations. However, the delay of the arrival time by two days made him feel extremely worried.

If there was no morning attack by creatures, he might not have done so. But judging from the situation in the morning, the other party seemed to have not tried his best. The fierceness of the war was entirely due to the way the creatures attacked, especially the thorn snake that retreated in the end.

This situation made Clarkins guess that the other party seemed to be tempting. Although he was not sure, he still didn't want to take this risk before the production line arrived.

It turns out that Major Clarkins' judgment is correct.

Zhu Tianxing was testing, and after the test was completed, he launched a large-scale attack again. For creatures, there was no need for war mobilization or rest. Everything on the battlefield could be simplified to one order.

At this moment, the biological army was moving here at a speed of 140 kilometers away. The bunkers and thunder on the human side were still tensely.

A short distance is nothing to the degree of creatures.

Unlike last time. This time there are tens of thousands of creatures.

If the creatures that were two hours ago were a torrent, then what is coming now is an ocean, an ocean composed of creatures.

When humans had not recovered from the fear of the last war, they felt the vibration from the face.

This vibration continues to increase from far to near.

"Come here. So fast." Major Krakins, who was looking at the electronic board in his hand, immediately stood up from the seat. Then quickly turned on the screen and switched to far-infrared mode.

Mini reconnaissance satellites in space also started working at the same time.

Suddenly, the alarm sounded suddenly. This time it was even more exaggerated. All outposts with a radius of dozens of kilometers showed a harsh alarm.

The pictures on each screen were forcibly switched to images sent back by satellites.

The biological ocean of all over the world is approaching the outpost at a very fast speed.

"Enter the combat post immediately." Such a sound came from the headphones of all soldiers and officers. Then, the warehouse doors of each dormitory were opened.

Tens of thousands of soldiers wearing red armor rushed towards the front protective wall with weapons. At the same time, the weapons on the protective wall also rose from below and pointed the shot port at the direction of the creature's arrival and inside the outpost. Some patios suddenly opened. Huge ion cannons also rose from the surface.

"Boom...boom..." There were loud noises, causing the entire outpost to shake like a shock.

Hundreds of light spots shot into the air instantly.

At this moment, the creatures were less than 40 kilometers away from the outpost ahead and were still running fast.

Suddenly, dozens of photoelectrics suddenly appeared above the front of the creatures, and were landing rapidly. The target was the sea of ​​creatures on the surface.

It is obviously too late to hide now.
To be continued...
