Song Jiahao did not notice the change on the workbench at all.

He stared intently at the changes in the virus under the microscope, completely forgetting about the dog whose leg and foot he had broken a few minutes earlier.

It's really not much to pay attention to.

Regarding Chen Po's fierceness and aggressiveness, Song Jiahao has a very clear understanding in the previous research process.

Therefore, for today's trial, he specially chose this puppy that has just been weaned for a short time. Small things have the benefits of small things———— teeth are soft, lack of strength, clumsy movements, and even if they are infected by a virus, they can be easily eliminated. I've tried it just now, and it won't even bite my fingers.

The dog's eyes suddenly widened with a thick killing intent. Words like plush cute have nothing to do with today's puppies.

Its body shape and volume have not changed, but its eye sockets are rapidly congested. The mouth slowly opens, revealing swollen soft tissue. Two rows of sharp teeth are sticking out. It is no longer the weak milk teeth of the past, but the hard fangs that are extremely sharp, reflecting the cold light of the forest in the light.

Song Jiahao didn't notice the anomaly behind him.

He was intently observing the blood sample under the microscope.

Although the blood was taken from Chen's body and then added with internal organs or fragments, body fluids or blood from other animals, similar sample analyses had been done many times in the past few days. But in today's sample made of fresh dog blood, Song Jiahao obviously found some very special content.

The main body is still those viruses. They are extremely aggressive and predatory. Therefore, it can cause complete damage to the host's physiological system in a short period of time, and the entire parasitic process can be easily completed. From this point of view, it is actually a kind of saboteur, a deadly weapon that has no reason at all, and all actions are aimed at killing existence.

There are two sides to everything, and this virus is no exception.

Among the infected cells underneath the microscope lens, several very small, but existent, variants have appeared.

They make up a very small percentage of the whole sample cell. Per cent...... No, it should be one thousandth, not more than two thousandths at most. The exact numbers need to be further validated, and electron microscopy and computer analysis are required to obtain accurate results. But no matter what, Song Jiahao feels that this ratio should not change much. He trusts his own judgment and has never been wrong.

These mutated cells, which are extremely rare, are easy to overlook. They account for almost no count of the total number of hosts. However, Song Jiahao still discovered the subtleties through the comparison of the appearance with ordinary infected cells.

They have thicker cell walls and are more divisive.

Most importantly, they seem to be able to create a wonderful communication with mitochondria, which in turn leads to control of infected cells at the source. This is important because it is equivalent to another new group of people that emerge as the virus mutates. And in terms of bloodline and ability, it far exceeds the normal form of infected cells.

If we use human beings as a comparison, the gray blood extracted from Chen Po's body is regarded as a miniature version of society. Among them, the common form of infected cells is the common people, that is, the group that is located at the bottom of the society and has the largest number. And this special virus, which has just been discovered by Song Jiahao, is equivalent to the most elite class in human society. They control a lot of resources, control more than 80 percent or even more of the wealth, and are the core of power at the top of the whole society. If human society is seen as a pyramid, then these special viruses exist at the top of the tower.

If the mysterious person who has been communicating with Liu Tianming through the Internet sees this situation, he must be very surprised.

Song Jiahao found that the difference between the two mutant viruses is actually a significant difference between the diffuse form of infection and the normal form of infection. It's just that, in Liu Tianming's view, the name of the diffuse type of infected body is very troublesome, and it is more appropriate to call them "walking corpses". The number of normal forms of infection is extremely rare, and the actual proportion of the population with a large number of diffuse forms of infection is almost 1/1000 to 2/1000 calculated by Song Jiahao before.

The conditions in the underground bomb shelter are limited, and you have to be careful not to be detected by outsiders. Therefore, Song Jiahao, the research equipment that was too large, could not get in. Now I use a very ordinary optical microscope. If he had used a more sophisticated device such as an electron microscope, he would have found that even among such scarce numbers of special viruses, there was a more refined classification.

In fact, human society has similar group distinctions.

Just like the rich are divided into millions, tens of millions, billions, and so on. If Liu Tianming saw this situation, he would definitely understand what the mysterious person on the computer once said.

Among the normal forms of infection, the number of infected individuals in the mutant form is extremely rare and very rare.

"It's the perfect masterpiece of heaven......"

Song Jiahao stared at the few particularly special black spots under the microscope, his face was intoxicated, and his eyes released endless surprise and shock. He muttered to himself, his palms drenched in sweat. It wasn't because of fright, but because of the discovery, he saw a whole new world that he had never imagined.

If these mutated viruses are successfully parasitic in the human body, the most direct feature of this is the multiplication of power.

Song Jiahao has a very intuitive understanding of biology. Although he has not yet done a detailed analysis of the virus samples, he is sure of this by comparing Chen Po with those before him.

The problem now is that the number of special viruses is too small.

In the case of Chen Po, although this particular virus is present in her body, it cannot form a large group with a control effect. Nutrients are the fundamental factors that determine the division of the virus. The range of food that Chen Po now consumes from the outside world is raw meat. The main population of this food energy supply is the normal form of infected cells. There are so many of them that they eat like crazy, and the special virus simply can't get enough energy. In addition to this, they also seem to require very different nutrients from the normal form of the virus. But what it is, Song Jiahao couldn't find a clue for a while.

Suddenly, there was an extremely violent noise behind him.

Song Jiahao hurriedly turned around, and the pupils in his eyes suddenly contracted, turning into incomparably small needle tips.

The dog strapped to the workbench was struggling.

Its shape, especially the head, has undergone a great change. The entire neck was elongated by an invisible force, more than five centimeters above its original size.

This unforeseen change should be caused by the proliferation of cells and tissues, or the mutation effect caused by a virus. It wants to break free from the bondage of the plastic rope, but it can't change its predicament for a while.

It opened its mouth, a beastly roar from between its sharp, hard fangs, and its bloodshot eyes were filled with hatred and resentment. The entire upper body twisted into a big angle, the three legs and feet could not move, and the mutated dog twisted its neck and slowly licked the wound on the broken leg in the back.

The severed hind leg has been attached.

Of course, this is not Song Jiahao's masterpiece, and he is also sure that he has not done anything like it at all.

There is no doubt that it is the mutant virus that has contaminated the surface of the wound that has produced its effect.

Although the disconnected hind leg is at a different angle from the other three limbs, and the direction of the knee bending is completely reversed, it has reconnected with the body, and the cells and tissues at the edge of the wound have begun to grow, and the muscles are intertwined from the inside out. Through the blood-stained hair, you can see the bright red subcutaneous part and the fine ligaments that reflect the silver sheen.

Song Jiahao stared blankly at the terrifying mutant monster on the workbench.

He never imagined that he would be the creator of such an ugly creature.

God, I never thought I'd create something horrible like this.

I, I, I just think it's small, easy to handle, and not aggressive. Even if I am infected by a virus during an experiment, it will not pose a threat to me...... But in hindsight, this notion is clearly wrong.

"Whew————"

The mutant dog lies on the workbench, and when it turns its neck, it makes a clear sound of bone joints colliding.

It looked at Song Jiahao with extremely fierce eyes, and the cold light in its eyes was like a wolf that had been hungry for a long time. In connection with its current immobile predicament, the sound coming out of its mouth should be a demonstrative intimidation. But in Song Jiahao's ears, it was like a tiger and lion and other fierce beasts sending out an offensive signal before hunting.

I need a weapon!

A voice in his head told Song Jiahao like this.

No, it should be a warning to him, a loud warning to him with the cruelest facts.

Scalpel? No kidding, that thing is just a toy right now.

Medical scissors? It's sharp, but it's as desperate as using a matchstick against a giant on such an occasion.

I, what other weapons do I have?

Large drops of sweat seeped out densely from Song Jiahao's forehead.

He quickly turned, grabbed his backpack, and scrambled through anything that could be used as a weapon.

He regretted it, why didn't he think about this earlier?

No, it was my negligence. I should have thought there would be danger. You should have a gun, a bigger knife, even a hammer!

Song Jiahao now finally understands why Liu Tianming rushed into his office that day and said those words to himself.

Po Chen is really dangerous, she is indeed an extremely unstable source of infection.

Although the basement has been renovated, once she gets out of it, the consequences are really unimaginable.

Now, it was Song Jiahao's turn to face this terrible danger himself.
