Whether it was the guard Tapa who had the first outbreak of symptoms, or the doctor who was killed by Gu Ji's own hands.

Not only can they communicate normally, but they also have basic thinking skills.

For example, resisting, calling, opening doors, and so on.

But compared to the zombies in the movie, these infected people will be less aggressive.

At least they won't rush up and bite people by the neck, scratch and scratch indiscriminately, and kill people.

If it weren't for the fact that his body was too weak at that time, Gu Ji would not have shot rashly and killed the male doctor directly.

Gu Ji tightened the Galil ACE rifle to his chest, pulled out his pistol and dagger from his tactical belt, crossed his grip up and down, and cautiously came to the door of the sixth staircase.

Carve followed, grabbing his shoulders with some nervousness.

"Sima, shall we just go in like this, do you want to throw something first and attract the attention of those crazy people?"

"Shut up."

Gu Ji let out a low sigh, and first used the cut corners to observe the situation in the corridor.

Visible to the naked eye, it is a central office observation area obscured by a half-height front desk.

On the left is a filing cabinet, while on the right wall hangs rows of LCD televisions, each displaying images from different laboratories and research values, including the temperature and radiation values of each room in the confinement chamber.

In the middle are a variety of desks and chairs.

It's just that now it's already messy, tables and chairs are crooked, all kinds of discarded documents are scattered all over the sky, and even the TV has been smashed several times.

And the most eye-catching thing is the pool of plasma on the wall of the entrance and exit on the left.

If you read it right, there is also a lot of yellow-green liquid mixed in it, which is brain pulp!

"You keep an eye on the right."

The observation area was flanked by a zigzag corridor, and Gu Ji could only focus on one side before handing the other side to Carf.

Although this woman is a little timid.

But she has survived until now, at least not stupidly.

So, Gu Ji turned sideways slightly, walked through the stairwell, and came to the door along the wall, turned the muzzle of the gun, and used the corner cutting tactic to quickly cut into the corridor on the left.

And Cave also did as he asked, moving to the right.

It's just that what Gu Ji didn't expect was that there was nothing on the left, except for the medical waste scattered on the ground and a few smashed glass shards, and no suspicious figure appeared.

He continued to move laterally, approaching the observation area.

It turned out to be a disgusting scene.

The corpse of a nurse wearing a chemical protective suit fell to the root of the high platform, and the whole head was like a watermelon that had been knocked out, and the face and skull were completely dented, and all kinds of yellow and red turbidity were splashed all over the ground.

Rao is Gu is used to seeing dead people, but he is inevitably deeply stimulated by the scene in front of him.

"Left side safe."

"Right, Right, Right ......"

As a result, as soon as he finished speaking with his front foot, Kafu stumbled backwards with his back foot, and when he saw the female corpse next to Gu Ji, he was so frightened that he jumped up half a meter high on the spot!

Gu Ji quickly turned around and stepped forward.

The muzzle of the gun is aimed at the center line of the corridor.

I saw that the dilapidated yellow-green lacquered walls of the entire corridor were full of traces of bloody handprints and plasma dragging, and a figure in a hospital gown was lying near the corner at the end of the corridor, not knowing whether it was life or death.

"Hold on to me, keep an eye on the rear at all times!"

Leaving the next sentence, Gu Ji took a gun and approached the target lying in the corridor on the right.

Carf followed closely behind him, grabbed his tactical belt with his left hand, held the dagger in front of him with his right hand, turned around in three steps, and looked at the hidden laboratory rooms on both sides from time to time, for fear that one of the rooms would suddenly open the door and rush out of a "madman"!

"Uh-huh......"

"Yes, there's movement! He, he's still alive!! ”

Just when Gu Ji walked halfway to the distance, he didn't expect that the "corpse" in the hospital gown suddenly let out a faint moan, which frightened Kafu so much that his face turned pale and he almost screamed.

"Shut up! Watch the back! ”

Gu Ji snorted coldly.

This is the gap between ordinary people and professional military and police personnel.

If Wu Kang was present, no matter what movement happened in front of him, he would not turn back, unless he received an order, just like Gu Ji would never worry about someone sneaking up behind.

This is the trust and tacit understanding between teammates!

The distance is closer.

Gu Ji finally saw clearly that the hospital gown lying on the ground was a middle-aged uncle.

His injuries were very serious, his hands were scraped by sharp weapons, his body was full of bloody holes, and next to his legs, there was a hardware wrench stained with minced meat.

It seems that the nurse in the observation area was stoned to death by him.

This is different from the zombie setting in the film and television.

Zombies don't attack each other.

But these infected people in front of them will indiscriminately attack any human, animal, or even inanimate dead objects, as evidenced by the smashed TVs on the walls and the shards of glass all over the floor.

"Ah...... It hurts...... It's so painful, it's fun, you're here to play hide and seek, ahahaha......"

The middle-aged sick number screamed in pain at first, but the shouting and shouting suddenly turned into wild laughter, which was completely unpredictable.

However, according to Cave, he was originally severely mentally ill.

"There's another person, where's that?"

Gu Ji didn't bother to talk nonsense with him, and he didn't even want to get close.

Don't look at the fact that he is wearing an M50 gas mask now, but he does not have a chemical protective suit, and the gunshot wound on his leg is completely exposed to the air, in case this virus can be transmitted through aerosols, then the closer you are to this guy, the easier it is to be infected.

"People? Where are the people? Damn it! You are all sinful! I'm going to kill you, kill ......"

"Whoa!"

"Ahh Be careful!! ”

Something has changed!

The middle-aged patient on the ground was venting his anger, when suddenly, there was a sudden noise in the room on the left, and a black shadow suddenly pounced on the door as soon as the door opened.

Carf screamed in horror.

Gu swept a few moments of light, only to see the cold blade attacking, and quickly reacted to the ground and retreated to avoid the attack.

Then the upper body rotated like a top, and the blade of the left hand flashed, "poof" a knife, stabbed horizontally to the opponent's shoulder, and stirred hard.

"Ah——!h

The blow missed, and the blade spun in the flesh, causing the black shadow to scream in unison.

If you want to pounce back, you can take care of the hind feet have already left the ground, twist your waist and turn your hips and knees, your front legs are like arrows off the string, your instep is straight, and you can sweep and hook it, and with a "snap", it hits the wrist of the black shadow.

This one foot down.

In an instant, the black shadow's wrist was numb, his five fingers were loose, and the metal weapon came out of his hand directly.

The footsteps fell, Gu Ji covered his face with a mask, his eyes were as cold as knives, he picked up the pistol in his right hand, aimed it at the black shadow's face, and smashed it in an instant, one more ruthless and heavier.

Not a few tricks.

The black shadow was already a collapsed nasal bone, an eyelid hematoma, a bloody face, and a kneel on the ground.

"This ......"

Carf had already run out of the room five meters away and hid.

Seeing this scene, I was so shocked that my jaw was about to fall.

After solving the last madman, Gu Ji pulled out the dagger, rubbed the gun on the hospital gown to remove the blood, and said, "Is there anyone else?" ”

"Yes, it should be gone!"

Carve hurried over.

"Then go find me a chemical protective suit, plus alcohol, gauze, and food!"

"Yes, I'll go right away!"

After seeing Gu Ji's bloody methods, Kafu dared not listen to him, turned his head and rushed into a room and began to collect the supplies he mentioned.

Gu Ji took a few steps back.

Begin to observe the two infected subjects closely.

There was a mistake in his previous inference, after these madmen were infected with the madness virus, it was not that they did not feel pain, but that they secreted a lot of adrenaline like normal humans fighting, which weakened the pain to a certain extent.

When it comes to the roots, it's still an emotional change: irritability, inability to control the desire to attack.

This is very similar to the symptoms of some psychosis.

In addition to genetics and external stimuli, the main causes of psychosis are damage to the dopaminergic system in the brain center, or the frontal lobe, basal ganglia, and temporal lobe.

To put it mildly, it means that the "brain" is broken.

So is it understandable that the pathogenesis of this unknown virus that can make people crazy is destroying the nervous system of the human brain?

This couldn't help but make Gu Ji think of a virus classification:

Neurophagovirus!

The most well-known of these viruses are rabies virus, herpes zoster virus, and HIV human immunodeficiency virus.

Without exception, neurophagoviruses are extremely harmful to the human body.

If you don't get vaccinated or treated aggressively as soon as possible, there's only one basic outcome: death!

The pathogenesis of their disease is also very simple.

It spreads into the human body through bloodstream or respiratory droplets, replicates in large numbers within the host cell, and spreads to the central nervous system and peripheral nerve roots.

Among them, the rabies virus is more special.

It will follow the nerves all the way up, invade the spinal cord and the entire central nervous system, destroy the neurons that invade the brain and cerebellum, etc., and eventually kill the host!

And the unknown crazy virus in front of us seems to have a very similar mechanism to this kind of neurotropic virus.

It is likely to stimulate excessive dopamine secretion by destroying neurotransmitters in the central nervous system of the brain, causing positive symptoms of schizophrenia, such as hallucinations and delusional aggression.

There is also the limbic system, if the amygdala is stimulated, there will also be symptoms of emotional out-of-control.

However, these are not the most important things for Gu Ji.

What he needs to address most now is how the virus spreads and where it originates.

Because the virus in front of him is a new type of virus that he has never seen before, it is impossible for him to study treatment options, vaccines and special drugs through pathogenesis.

To put it more bluntly, even a country can't do it in three years and five years.

Unless a few superpowers work together, it will have to be measured on a monthly basis.

So.

The quickest way to solve this crisis is to lock down the source of infection, first "strangle" the source, and then isolate it accordingly by determining the mode of transmission.

Only in this way can this "zombie crisis" be truly solved.

Relying on the armed blockade of those police outside alone is completely self-consolation and has no effect.

Don't forget.

All the members of the extremist group have fled in advance, and among those who have retreated, there must be people who are infected in the incubation period with the virus.

When the time comes, when they break out, they will bring the virus into society.

First the city, then the region.

In the end, the whole of Nepal will probably fall with it!!

"Suck and slip~"

Just as Gu Ji was deep in thought, suddenly, he felt a hot nostril, as if there was snot flowing out.

He subconsciously sniffled.

But soon I felt some mucous liquid pouring into my throat, first a fishy sweetness, and then a strong rusty smell.

It's blood!

Gu Ji's eyelids jumped.

Bleeding is also one of the symptoms of radiation sickness.

He hurriedly pressed the Geiger counter on his shoulder, and with a "buzzing" sound, he measured a value as high as "1904" millisieverts.

", what the hell are these guys working on......"

Gu Ji scolded and stepped back, using the Geiger counter as a detector to find the area with the lowest radiation.

At this time, he already felt waves of nausea welling up in his chest, and his head began to faint, as if he had hypoglycemia, and his eyes were black.

In the next second, a figure suddenly appeared in front of him.

Gu Ji instinctively raised the pistol.

"Ahh Don't shoot! It's me! ”

Kafu exclaimed, and hurriedly took the chemical protective suit to block the front, "I have already found what you want!" ”

"Quick, help me in!"

Gu Ji was already so weak at this time that he seemed to be able to fall down at any time.

Kafu didn't know what was going on, and thought that she hadn't eaten for too long, but right now, except for Gu Ji, no one could protect her and let him leave this murderous experimental area.

So she honestly helped Gu Ji into the office next to her and locked the door.

Enter the house.

Gu Ji glanced at the Geiger counter and confirmed that the value had become low.

Only then did he endure the dizziness and nausea, and took off his equipment and coat, but the pistol was always in his hand to ensure that he could control the situation at any time.

"Alcohol! Quick, sprinkle all over my body! ”

"Good!"

Cafu did it all.

After being disinfected all over the body, Gu Ji put on this set of gun-gray military three-defense uniforms, and put on a set of tactical vests, belts and other equipment.

So far.

He can truly achieve 360-degree protection without dead ends.

"All the supplies are here, but I can't find food......"

"It's okay, there's something to eat down there."

Gu Ji covered his head, sat down to rest for a while, and suddenly felt more comfortable.

At the mention of this, Caph's emotions immediately soared, but she quickly retreated.

"But, how can we go down, the access control system has been sealed, the door is all metal, even with a gun can't be opened, and we don't have an IC card in our hands......"

"Who said you have to go through the main entrance?"

As he spoke, Gu Ji turned his head slightly.

Following the direction of his eyes, Carf saw the window of her office.

In order to prevent patients from committing suicide when they lose control of their emotions, the windows of the psychiatric hospital cannot be fully opened, and metal security nets are installed outside.

But compared to the access control system.

The probability of this thing being damaged by a gun is greater.

Gu Ji got up and opened the window, which could be opened inward, but there was a steel bar the thickness of a little thumb outside, he touched the edge of the protective net and found the fixing bolt, "Next to the middle-aged infected person, there seems to be a tool wrench!" ”
