A long siren sounded in the corridors, and there must have been a backup power generation facility at the base to prevent an emergency like this one from happening.

However, the deaths of thousands of survivors and garrison defenders have failed to trigger a siren, so is this brain-hiding room more important than all of them?

"No—"

"It's going to explode!"

"Let's go."

Luo Luo, the person in charge and Luo Luo's brother 'expressed their opinions' in the face of the impending explosion, and the dull and long alarm always made people feel depressed and panicked, so I pulled Gu Yu to turn around and walk towards the way I came.

Suddenly, I felt a wave of dizziness, Gu Yu hurriedly helped me, I shook my head and said it was okay, and continued to walk quickly towards the medicine warehouse.

"This room is a mechanically controlled elevator, and the designers are also afraid of unexpected power outages." As for why it is particularly slow, it is because the contents of the medicine warehouse are just camouflage, and if the elevator is too fast, it will shake several things over each time it starts, which can easily arouse the suspicion of others.

Gu Yu looked back at the corridor and didn't see Luo Luo or her brother, but the cry like a tide floated over like a ghost.

"Don't look at it, Luo Luo won't leave her brother, and their brother and sister will die together." I saw through Gu Yu's thoughts, pulled him and quickly rushed into the medicine warehouse to activate the ascent mechanism.

"Can't her brother go along?" Gu Yu waited for the room to move up before he spoke, he knew that everything was a foregone conclusion, and now he asked just to find out the reason why I left Luo Luo's brother without even trying, obviously he believed that I was the reason.

"He's the IM plant." I rubbed my head, which was still a little dizzy, "He injected IM into his body and became the source of infection, and the sea of brain pulp we see is his masterpiece." ”

Gu Yu didn't speak, he looked at me fixedly, and when I continued to explain, I exhaled, and these things were clearly imprinted in my mind at this moment, as if I was also a witness.

"The new virus infected by the survivors and the garrison is an improved version of IM, and the military originally wanted to use it to treat the zombie virus, and there were indeed two successful cases at that time, but unfortunately these two people only lived for 48 hours.

One hanged himself in his room, and the other jumped into a cistern and drowned. ”

Speaking of this, I had to stop and sigh, "Everyone thought that they couldn't accept that they had eaten people when they became zombies, and they chose to commit suicide because they couldn't bear the psychological pressure." ”

The medicine warehouse stopped, Gu Yu pushed the door and ran into the corridor with me, the alarm sounded more and more urgently, he didn't need to save any more abilities, and directly took me back to the surface layer by stepping on the air ladder.

Despite the urgency of the situation, we went to the person in charge's room to take a look, and he said that he still had a part of his body alive and that we hoped we could help him.

However, there was only a shriveled corpse in his room, and he was not infected, trapped alive in the room.

"Let's go." After Gu Yu checked the body, he was sure that he couldn't die anymore and there was no possibility of saving him, so he called me to hurry up and continue running outside the base.

The self-destructive explosion of a base, even if we are protected by Gu Yu's air cover, we may be bombarded into the sky, once the air cover can't withstand the high temperature and melt away, it is not a joke, so we better run as far as we can.

We rushed out of the base gate in one go, and as soon as we ran out of the gate, we heard a strange muffled noise from underground.

Then the scene of being sent into the sky by the air wave does not happen, on the contrary, we feel a strong suction, as if we are just two small iron nails, and behind us there is a magnet the size of a grinding disc that is 'beckoning' us.

Towering courtyard walls, barbed wire, airplanes, trucks, and even the surrounding ice, snow and debris were all sucked into the center of the base by this force.

The base gate behind me catapulted backwards, and I felt the air shield around me be distorted by this terrible suction.

"Hold on!" Gu Yu held my hand tightly and unfolded an air shield, like an upside-down bowl, covering the entire base underneath, while Gu Yu and I were isolated, and then the amazing suction suddenly disappeared.

In an instant, the location of the base had turned into a huge crater, into which everything on the ground was sucked in, including the snow on the surface.

It was a gravitational collapse explosion with no heat, but it was no worse than gunpowder, and the base disappeared in an instant, and the falling rocks and soil buried everything, and we couldn't see what was going on below.

I stepped away from the edge of the pit and tucked away my long hair, my heart still trembling, if it weren't for Gu Yu's quick reactions, we would have been squeezed into meatloaf by gravity in the blink of an eye.

The term 'gravitational bomb', which only appears in science fiction, has just detonated under our feet, and we have already experienced its power.

"Go on." Gu Yu waved the air shield and picked up the previous topic and asked.

"IM is infected through drinking water, the incubation period is 72 hours, 72 hours is the limit, the general infected person will have an attack within 24 hours, the human brain will be separated from the body, the separated brain plasma, will eat up the body as nutrients, and then after a period of time, the brain plasma that has no nutrients to absorb will automatically decompose."

The traces that Gu Yu and I saw in the arsenal were the marks left by the automatic decomposition of the brain, and the only thing it couldn't decompose seemed to be stones.

As a result, the floor of the base, the plastered walls, it can't decompose, which is why we haven't seen survivors' clothing and belongings.

The mutated brain not only eats its own body, it also accelerates the breakdown of contacts.

Whether people are escaping or hiding, as soon as the mutation time limit is up, they will be like baby orangutans, and their human brains will be separated by IM in an instant.

The brains found by the little robot in Area B in the video are actually fused with many brains, as are those in the elevator box.

"Any other information?"

"When he ran out of food, he thought of IM, a bacterium that can cure all diseases and make people immortal."

"Results ......"

"As a result, he became their leader, and as long as they were by his side, they would not break down due to lack of nutrients, but they would have to stay asleep until they had a new replenishment."

"What about those cries?" Gu Yu asked after being silent for a few seconds.

"God knows, maybe it's the resentment of the survivors trapped after death, it's not brainwaves anyway."

Big Mac Brainwave is Luo Luo's brother, and those brains have become his limbs in disguise, so although they are brains, they are not real brains.

"Those black shadows are all kinds of mutant beasts collected by the base, they prey on humans, and they are also the prey of IM, without them, Luo Luo her brother would not be able to hold on to today. Oh, and the reconnaissance team sent in by the New Human Alliance, which is also in that sea of brains. ”

IM is at the top of the base food chain, and when it has nothing to eat, it chooses to go into dormancy to preserve its vitality.

Luo Luo's brother is just maintaining the appearance of a human being, his core has long been infected and mutated by IM, the so-called immortality, but it has become a monster.

Gu Yu looked back at the giant pit, "IM can really treat zombie viruses?" ”

If I said yes, he would have turned back and dug up the remains of her brother, I knew him too well.

"No, it just turns people from zombies into another kind of monster." I sighed helplessly, "Those two success stories are not suicides at all. ”

I'm sorting through the information that Luoluo's brother has sent into my brain, all of which is related to the base, and it's clear that he's sifting through it while it's being delivered.

"He went to the real sample bank and read this top-secret message, after the two people received the IM injection, one had a nervous breakdown, which you can understand as a rejection reaction, and the other was controlled by the IM, and jumped into the reservoir in order to allow the bacteria to spread and multiply."

Of course, there was nothing abnormal in the man's brain after death, so the military only routinely took samples to test the water quality, found no problems, and therefore did not stop the water supply.

Catering to the water supply of thousands of people is no easy task, especially since the base was built without any intention of turning it into a containment station.

Survivors' dormitories and many facilities were urgently renovated two months before the end of the world, and the water treatment equipment barely maintained the daily water supply.

Once the water is cut off, the consequences are very serious, but now it seems that the consequences of not stopping the water are even more serious.

"Do you remember what the person in charge said about the disappearance, those people are not missing, they are decomposed. From the first infected person jumping into the reservoir, to the first case of disappearance, which was only 24 hours, to a full-scale outbreak, at most 72 hours, so many people disappeared in three days, no wonder the person in charge said that the survivors were clamoring to leave. ”

The time for bacteria to fully occupy the human body varies slightly from individual differences, but most of them occur at the same time, and all infected people have only two outcomes, crazy or mutated.

We don't know what the crazy ones did, they killed themselves, they killed people, and their bodies were dragged away by mutants who escaped from the ground.

I estimate that it was precisely because of the guard mutation in the sample library at the bottom that the mutant beast in the glass jar successfully escaped from prison, making the already disaster-stricken base even worse.

And the person in charge, he has already died, but he is unwilling to accept the reality, hoping that IM can help him resurrect.

As for the mutant beasts, they have become the nutrients of IM, according to Luo Luo's brother's observation, mutant beasts cannot be infected by IM, but IM will hunt them.

The time when the robot was stuck in the brain was actually a trap set by IM to hunt living creatures passing by.

Fortunately, the robot can spin at high speed, and it will immediately shake off the brain that is sticking to it, otherwise it will also decompose and disappear.

"That room is the core laboratory, and the information we are looking for must be in the infected body." Gu Yu looked very sorry, the infected body he said should be the sea of brains.

In order to protect the core secrets, the base has installed a self-destruction device, and now the base is buried deep in the ground along with all the research results, and the IM without nutrient absorption will not live long.

Maybe it will go back to hibernation and wait for the next batch of discoverers, but it definitely won't be me and Gu Yu, even if we dig up other research results stored in the sample bank, I don't dare to let them see the light of day without rigorous testing, this is the lesson left to us by the Snow Mountain Base, for which they have paid thousands of lives.
