The undead communicate with each other as if they didn't need to open their mouths to spit out clear words. And such exchanges are generally very short-lived, but they contain a lot of information.

The institute was clearly still in use, at least until they opened the protective doors of the institute. When they violently opened the protective door, the air inside the research institute was quickly lost. The cold to the bone marrow instantly pulled the temperature of the entire research institute to the lowest level.

The dozen or so masked guards who were originally guarding behind the door had almost no defensive effect, and they were frozen to death in an instant. They are the only guards of the Institute. They didn't think about the Institute being invaded in the first place. Knowing that the temperature on Pluto would kill them instantly, they still came here with laser guns.

If they weren't guarding here, they would have to resist in the research room, but it would be easy to destroy some of the valuable equipment. Even though they knew that the probability of survival was low, they still came here to meet death.

The burly alien led by him slightly tilted his head to look at the guards around him who instantly froze into ice sculptures, and then walked towards the interior of the research institute. Pluto's atmosphere is mainly composed of nitrogen and carbon monoxide, and the planet's main components are rock and ice. The institute established here has been more than a kilometer underground, and the earth's crust is still moving so frequently that there is still a strong heartbeat beneath Pluto's surface.

The vast majority of the Institute's energy comes from geothermal energy. At this moment, inside the research institute, behind the closed door, some researchers are trying to destroy the materials in the research institute. Almost all of the research here is related to human beings themselves. If the information here is known to the undead, God knows how the undead technology will create weapons to destroy humanity.

A large number of materials and storage cards were destroyed in the flames, and many paper materials were scattered on the floor. At a time when paper is rarely used on the planet, it is used in large quantities. Maybe they feel that it's safer to use documents than computers. After all, there are countless highly skilled electronic thieves of all kinds. Putting it on paper is the safest thing to do with Pluto.

But now, a large number of paper documents need to be destroyed, but they regret such a way of secrecy. A worker spills a jug of alcohol on a large amount of manuscript paper and then lights a flame.

When the entire research institute was in chaos, the undead warrior at the head was already standing at the final gate with a team of soldiers.

Looking up at the alloy gate in front of him, he could see the surveillance in the corner of the gate, their movements were all under the monitoring of the Institute, but no one could stop them. Just now, the last dozen or so guards were also frozen to death by the cold air pouring in from outside the gate that opened instantly. Originally, it would have been easier to break through the defenses and open the gates using Earth's backward software technology, but the guards destroyed all the entrances, leaving only a cloud of charred black and debris.

So the undead moved a little slower. But it's only a little slower. In front of the hot melt gun, even if it is the last alloy guarding the door, it is only a matter of time before it opens.

The institute was equipped with training armor and BX heavy armor, but those were used by the warriors who originally guarded the corridors.

Now that the warriors of the undead are standing here, the fate of those guards is known without even thinking about it.

Inside the institute is a crazy world, where a researcher shoots his former colleagues one by one with a laser gun, while some researchers search around for a safe place to hide, fire, smoke, blood, and wailing.

And beneath the depths of the Institute, a group of unclothed test subjects looked up with their indifferent eyes. They could naturally feel the terrifying atmosphere in the research institute, and some blood donations were leaking down the cracks.

They were once allies of the Allies, but during World War III, they lost their homeland. When the Allies sent criminals back again, they were also brought by hiding in warships.

At first, he said that he was going to take them to the Martian colony, but he ended up here.

A laser falls from above, killing one of the test subjects in an instant. The heat of the laser stabilized the wound again, and he didn't shed much blood, and he fell to the ground so softly. The high temperature of the laser burned the nerves around his wound in an instant, and he didn't even feel much pain, so he collapsed next to his companion.

But no one around him cared about him. Their nature has not changed for so many years, and it has even penetrated deeper into their souls. It is a nature to fear the strong and oppress the weak. Now they are on the weak side, but the anger in their hearts can destroy the whole world.

They watched in silence, without any emotion in their eyes. Over the years, the Allies have conducted all sorts of experiments on them. Experiments that most people can't imagine are performed on them. They used to experiment with others, but now it's them.

A country without territory is not a country, but a wandering people, and a wandering nation will not have any dignity. Because they have no one behind them to protect them.

This is the sorrow of the Red Sun people, who have hurt their own people to help the allies complete some human experiments, and after they lose their territory, the allies will classify them all as experimental mice.

There was a frenzied pleasure to see the madness of those allied researchers, under their calm gaze. In the rendering of fear and death, such a calm makes people feel the horror of this nation deep in the bone marrow.

It didn't take long for the institute to be covered in the cold. Without the protection of the soil, it is impossible for the institute to maintain the right temperature and oxygen. And the undead do not need prisoners of war, death is the best gift for them.

And under the research institute, the pair of crazy glasses still looked up at the top, and until death, they looked up like that.

"This seems to be a research institute." Looking at the surrounding equipment, these are considered the most advanced equipment on the earth, but these undead don't look at it. They looked at the institute, the corpses were frozen, and there was even an allied scientist holding a gun at their ice sculpture. He was covered in a layer of crystal frost.

The heat in his body dissipated instantly, and a small amount of water vapor condensed a layer of frost on his corpse, clinging to it.

And the breakthrough of the research institute also announced the demise of the Red Sun nation, which once had a glorious history, and all their clansmen are here. I don't know if people in the future will remember such a nation. However, if the affairs of the research institute are exposed, people may still remember such a nation, but the allies will definitely not admit and expose such a thing.

This nation that once helped the allies do evil, a nation that bullied the weak and feared the hard, disappeared in this way, perished at the hands of their former allies.

And such a thing was destined not to be known, because even the Allied fighters who came later did not know what was going on here. They were ordered to come, and if they could save the scientific researchers here, they should be rescued first, and as for the "white rats" under the research institute, they were not interested. If it's too late, they'll blow it up. Let this institute be an eternal secret under Pluto.

The communication of the undead was fast and low.

"I just received the news that the humans have defeated the team on the three detons." An undead whispered. He looked around at several captains. It wasn't for them to think about why the weak race called their race human. And some basic knowledge about humanity, they have already learned from the awakened human warriors.

Yes, they call awakening when they transform dead humans into undead.

"The people here can wake up, and then we will be stronger." The undead warrior led by him said in a deep voice that he knew about the battle situation on the three guards. Now that the humans have sent warships, they will definitely bring more troops in the future.

Just as Major Ye Feng thought, he originally wanted to eat this previous team. But there was not enough time for him to send more soldiers. I can only give it a try and see if I can give them a heavy blow.

"How's the other side doing?" Compared to the level of understanding of the undead by humans, the undead can already be regarded as proficient in humans. After all, there are "awakened" human warriors who explain the situation, and the undead know more about humans than humans think.

"The fighters of the allies are not worth mentioning. But the forces of the Entente and the Celestial Empire were very difficult to deal with. "Recruits will suffer the most casualties when they first go into battle, and if they survive the first battle, they will be much braver after that.

nodded, "They should come to us later, protect the hot melt cannon, and send out vicious dogs, I hope they can escape the pursuit of vicious dogs!" At that, several of the undead warriors laughed.

The Vicious Dogs are from a planet full of lava, and after taking over it, they found the creatures in a brutal environment and awakened them. They are excellent scouts and hunters. After waking up, it became even more terrifying than before.

Let the vicious dogs that are not very large deal with the weak body of humans, and even have some suspicions of bullying humans.

But this time, it was precisely because of the presence of vicious dogs that they were able to quietly invade here. If it weren't for the fact that they didn't know that there was a research institute and passed on the information, they would have been able to grow on Pluto for a long, long time until they were strong enough to face the entire human alliance.
