Chapter 544

There is a ghost that has been lurking in nature for billions of years, lurking around us.

It's prion.

The existence of prion is very old and its distribution is very wide. Cattle, sheep, deer, human And so on, there may be prions in animals.

Prion will erode the biological nervous system, make the neural circuit of biological brain chaotic, leaving only the instinct of eating and reproduction, and become crazy and violent, which is equivalent to becoming a "zombie".

Prion, also known as "zombie virus".

This is a very special and strange existence.

So far, the scientific community is still unable to figure out what prion is.

In essence, prion is a protein molecule, it is not a virus at all.

The virus is composed of a layer of protein wrapped in the viral DNA. However, prion has only protein molecules, but no DNA. It is the protein itself.

In principle, without DNA information, there is no condition for replication and proliferation Prion, on the other hand, has the ability to replicate. It can transform other normal protein molecules into prion protein molecules.

It's just It's so unscientific!

No DNA information, no transcription template, how do you complete the replication?

In the scientific community, prion replication principle is still a mystery.

In addition to this, the terrible thing about prions is that they are essential components of life itself - proteins.

We know that protein is the basic component of life, and it is also an essential component of life.

Every cell is absorbing protein all the time. As a protein molecule, the invasion of prion is almost unprotected!

Seeing that the zombie virus is a variant prion, Lu Li's heart has cooled.

Prion, it is no solution!

In the real world, there have also been outbreaks of prions.

Yingjili's mad cow disease incident was caused by prion infection.

Zombie deer in North America are also caused by prion infection.

The event of prion infecting human beings also happened in the real world.

In the human genome map, chromosome 20, gene fragment contains a horrible and frightening truth.

This gene fragment, the gene information expressed, is suddenly the antibody gene against prion.

As we all know, having a certain antibody means having been infected with a certain virus.

Gene 20 reveals a frightening and terrifying truth. Long, long ago, all primitive humans were infected with prions.

Imagine that there was a large-scale outbreak of "zombie virus" in the primitive population, and all people became zombies!

Perhaps the ancestors of modern humans were survivors of the zombie virus.

Maybe The more frightening conclusion is that modern people are all the descendants of "zombies"!

This is so creepy!

Now, in front of Luli, it is also the end of the world caused by prions.

In the display of the electron microscope, Lu Li clearly saw that the zombie virus in this simulated world also has the characteristics of prion, and must be a variant of some prion.

The prion mutated.

Even if the human gene contains prion antibody gene, it is still unable to resist the more fierce and violent mutation of prion.

Prion itself is terrible.

This mutated prion is even more terrifying.

Now How can we solve prion?

No matter taking the route of "salvation", or "destruction", or even no route, Luli must also fight against mutant prion.

I'm so hard!

Even as the world's top geneticist, Lu Li felt powerless.

All known antiviral methods can't kill prions.

The prion can still survive at 600 ℃. Prions can swim in 75% alcohol.

Only when the bones of the sick cattle are burned to ashes in a high-temperature furnace, as yingjili did in the treatment of mad cow disease, can prion be killed.

To eliminate mutated prions in this world, do we need to burn all the animals in this world to ashes?

It's easier to blow up the earth in the world.

Lu Li is helpless.

The task of fighting prion is too difficult, but Luli has to do it.

Study this mutant prion first!

In the virtual laboratory, Luli has carried out detailed detection for the mutated prion samples.

Even Luli also invented a normal human experimental human body to observe the infection mechanism of mutated prion.

Through a series of experiments, Lu Li also had some knowledge of this mutant prion.The structure of this mutant prion is very complex.

In addition to the core part of prion itself, it also combines the characteristics of rabies virus, and even the pathogenic characteristics of hemophilia.

Prion has the characteristics of zombie virus, plus rabies's madness and aggressiveness, as well as the violent characteristics of bloodthirsty, which is simply terrible.

Such a virus, enough to destroy everything!

Fortunately, this is just a simulation plot. If this kind of virus appears in reality, it will also become the end of the world, totally unstoppable.

Lu Li gave a long sigh.

For this mutant prion, Luli is still at a loss.

Prion is just a kind of protein! It's a necessary ingredient for all living things, a completely defenceless ingredient. All means of targeting viruses and bacteria have no effect on prions at all.

This ruled out the possibility of all antibiotics.

As for gene editing technology? Prion has no genetic information, it is just a protein molecule, without any genetic information. You don't even have genes, you still edit a hair?

This is the most difficult plot Lu Li has ever encountered.

Even as the most top scientist, Lu Li felt helpless, unable to find a research direction or train of thought.

Fortunately, the transmission mechanism of this mutated prion is not too bad.

In addition to body fluid transmission, it is mainly the most common "bite" transmission in zombie films.

In addition, mutated prions do not infect plants. So, in this zombie doomsday world, plants are safe.

Fortunately, the mutant prion does not infect bacteria. Otherwise There is nothing left in the world.

Waving to close the virtual laboratory, Lu Li is helpless. Mutated prion can only be studied slowly and figured out slowly.

Now Get some sleep, tomorrow!

It turns out that zombies still need to sleep. Lu Li has proved it himself.

…………

The next morning, when Lu Li woke up, it was just dawn.

Lu Li didn't sleep until he woke up, but I woke up hungry.

Hungry! The instinct to eat broke out again.

Lu Li's eyes were red with blood, and his mind was pounding like a tide.

"Open the mechanized mind!"

Lu Li quickly entered a rational state to resist the bloodthirsty fury brought by the mutated prion.

Entering a rational state, Lu Li turned over and got up, put on his clothes and went to the bathroom to wash. Then he went downstairs to the kitchen and picked up the packet of barbecue.

European villas have fireplaces. Lu Li chopped a log table with a Miao Dao, lit the fire and reheated the barbecue.

And then Again, I ate several kilos of barbecue.

Lifting the mechanical mind, Lu Li breathed a long breath.

Food is a problem!

The rest of the barbecue will be finished soon. What's next?

And Lu Li thought of another problem. If zombies mainly feed on human beings, what do hundreds of millions of zombies eat when there are few human survivors?

Go out and have a look!

One is to find new food sources, and the other is to study the living rules of zombies.

Thinking of this, Lu Li turned to go out with a Miao Dao.

There are cars in the garage of the villa.

Luli had seen it when he was cleaning. In addition to another "big G" SUV, there was also a Yamaha R1 motorcycle.

Entering the garage, Lu Li only found the motorcycle key beside the motorcycle.

Pick up the key and press the start button, the motorcycle can even start. Although the amount of fuel is not much, we should still be able to find gasoline in the gas station outside.

With a long knife on his back and a motorcycle on his back, Luli rushed out of the villa and galloped along the driveway in the community.

A moment later, Lu Li came to the gate of the community.

And then He had to get out of the car.

In front of the gate of the community, there are a lot of cars. The scene was full of collision marks.

Obviously, this is where the zombie virus broke out. People rushed to drive and ran away, crashing into a pile in chaos.

Countless broken clothes were scattered around, countless bloodstains were left on the ground, and more were gnawed bones.

Through the dusty window glass, Lu Li saw the remains of a woman in a car full of scratch marks in front of him.

Walking up, Lu Li knocked with the handle of Miao Dao, broke the window, and saw the body in the car.

She should have been a beautiful young girl.

Perhaps, she is still a goddess in many people's minds.

Now She has become a rotten corpse.

Rotten?Lu Li quickly picked up a piece of broken glass, scraped it on the corpse, and scraped off some rotten tissue that had not yet dried.

Generally speaking, 15 days after death, the human body will be completely decomposed. After three months, the body will turn into a mummy.

Now This corpse, which has not been gnawed by zombies, can even scrape a little bit of dried tissue. In other words, it has not been more than three months since the zombie virus broke out?

More than 15 days, but less than three months, maybe about two months.

Has the world been destroyed in such a short time?

Lu Li sighed and threw away the broken glass.

First move these cars and open a road!

Although he became a zombie, Lu Li's original physical quality and true Qi internal power did not disappear, and he could still operate freely.

The physical strength of more than four tons, coupled with the catalysis of real gas, was enough for Luli to lift and throw away these cars and SUVs one by one.

Soon, Lu Li cleared out a passageway at the gate of the general community at the scene of the large-scale traffic accident.

Turning around and stepping on the motorcycle, Luli rushed out of the gate of the community and into the road outside.

In front of me Cars everywhere! There are traffic accidents everywhere!

It's a mistake for me to ride a motorcycle!

Lu Li, with a depressed face, leaves his motorcycle outside the gate of the community and walks on foot with a Miao Dao.

Outside the community is a main road, on the left is a commercial street, and on the opposite side of the road is a park.

On the top of a hill in the park, Luli can also see a towering TV Tower.

It's just I'm afraid nobody's watching TV now, right?

Lu Li sighed and turned to walk in the direction of the commercial street.

We should be able to find new food sources in the commercial street, and the flow of people in the commercial street is huge, so there must be zombies.

Why? I've been out for a long time, and when I moved the car just now, it was banging. Why didn't these movements attract the zombies?

Where are the zombies?

Lu Li had some doubts.

Carrying Miao Dao all the way forward, Luli soon walked to the commercial street.

It's a mess. The original prosperous scene, now no longer exists.

After a glance, Lu Li still didn't see the zombie. There's no zombies like those seen in the movies, which are wandering around.

The zombie in this world is still a kind of creature, or an animal.

They're not living bodies, they're still living creatures. So Do zombies still have some biological habits?

Lu Li didn't think much about it, so he walked to a supermarket in front of him.

This is a large supermarket.

The whole supermarket has five floors, which can be regarded as a large shopping center.

The entrance to the supermarket is not surprisingly messy. All kinds of broken debris spilled all over the ground, the ground was bloodstained, and there were many gnawed bones.

Obviously, there has been a tragedy here, maybe more than one!

Lu Li sighed and walked into the supermarket.

And then He saw the zombie.

Next to the supermarket cashier, a zombie squats on the ground, burying his head and gnawing at something.

This zombie was supposed to be the security guard of the supermarket. He was dressed in tattered security fees and covered with blood. There was a pool of blood flowing on the ground, showing a strong smell of blood.

Zombies What are you eating?

Lu Li slightly frowned and had some bad guesses in his heart.

At this time, the zombie, who was engrossed in gnawing, suddenly stopped and turned to look at Lu Li.

A bloody face appeared in front of Lu Li. Bright red mouth, and a drop of blood dripping.

The zombie stares at a pair of blood red eyes, stares at Lu Li, and his nose stirs, as if he is smelling something.

A moment later, the zombie roared at Luli, but did not attack him. The roar seemed to drive him away.

Is this animal food protection?

Is it declaring sovereignty and preventing me from robbing its food?

Sure enough, the zombies didn't attack at the first time.

Because I'm a zombie, just like it!
