With the replacement of hosts one by one, Yi Chen is becoming more and more familiar with invasive infections.

As a result of his long immersion in knowledge, he has even abandoned the question of time, and even somewhat forgotten his true human identity.

Other than that

Yi Chen also has a general understanding of the old world (before the lockdown) with the help of the hosts' memories.

The source epidemic area can be compared to a large country in the human world, and the patients who come out of the source epidemic area are much higher in status, and even enjoy a lot of privileges.

Most of the patients born in the old world also have the same goal, and through their own unremitting efforts, they have been certified by a source epidemic area, accepted as an insider, and obtained the corresponding disease system.

In addition to the source epidemic area, there are also a large number of neutral cities and countries in the Old World, but many neutral cities cannot get out once they enter...... Even privately it is possible to produce a table of "urban survival rates".

After all, the fertility of the sick is much stronger than that of humans, and it is not uncommon to see a female squatting in the wild, and within a month, children crawl out of the hole.

In order to stabilize the population, there were no laws in the Old World, let alone the so-called individual rights.

And very importantly, the most different thing from the human world is that the sick make perfect use of the world space.

The ground is only the most superficial layer, and it is home to the weakest group of patients, but it is also the most diverse, the most likely place for the birth of new types of patients and infinite possibilities.

Most of the sick people live and move in underground areas, such as the [source epidemic area] is located in a deeper and more dangerous area.

There are special connecting channels between the different levels, which are often located between some large neutral cities, and there are fees to pay for access, identity verification, and even some special things.

The reason why everyone pursues the depths and the source epidemic areas are also established in the depths is very simple.

The Old World, or the unique living world of Focus of Infection, has the earliest and most primitive pathological roots in the deepest places.

Therefore, the closer you get to the depths, the more you can establish a connection with the source of the disease, and the easier it is to gain growth and understanding.

All in all.

Judging from the memories ingested by Yi Chen's parasitism, this world is quite powerful, so powerful that Yi Chen doesn't know how to describe it at all.

Even if one of them comes out, it can easily destroy the existing gentlemen organization of the human race, and even if Zion City wants to move in, it can only take root on the surface or the second layer at most.

This situation also made Yi Chen extremely puzzled, why the old world, which was so powerful and suffocating, was actually blocked by the world, and even the most fundamental rules were locked.

Fertility isolation, quantity lock-in, and even disqualification from death......

The giant sword that penetrated the black sun and plunged into the earth, Yi Chen still remembers it clearly.

Forcing the old world to survive only through "world parasitism".

Who did it? It is not known, and there must have been a major war at that time, and many source epidemic areas were wiped out in this war.

Only a few powerful source epidemic areas have been retained, and they have all been greatly weakened, and the overall strength is far less than at its peak.

……

There is no concept of time at all.

As a epileptic virus, Yi Chen has long adapted to and even accepted such a life.

More than 5,000 people have been infected by him, 93% of whom have been successfully indoctrinated.

Even in the process of indoctrination, Yi Chen has developed a spiritual network that belongs to him, as long as he is on the surface of the old world, he can get in touch with these indoctrinated people at any time, and even conduct 'online teaching'.

Slowly,

A special group was formed, and for some reason Yi Chen temporarily named it [Yuan].

Always stay in the surface area and have no intention of going to the depths of the Old World.

Yi Chen knew very well that with his current state of the virus, even if he wanted to go deeper, he would not be able to go deeper, and if he provoked a certain source epidemic area, he might be wiped out.

But

Although there is no physical depth, Yi Chen continues to seep deep at the spiritual level, leaning towards the root of the disease.

When the knowledge he has absorbed is sufficient for his final evolution, he gathers all the indoctrinated sick in a no-man's land.

With Yi Chen's parasitic host as the center, it is surrounded by layers and sits around.

Integrating everyone's mental power to "signal amplification", so that Yi Chen's spirit has the most direct connection with the source of the disease, which will be an excellent opportunity for patients to open source.

The host controlled by Yi Chen sat cross-legged.

Click!

The entire skull is pinched upwards by cerebral tentacles, revealing an extremely active brain.

At this moment, the epileptic virus also completely opened the "characteristic capsid", releasing the internal brain to fuse with the host's brain nucleus.

The active brain is blackened and wrapped in pin-and-needle chains, spilling with a dead and metallic sheen.

If there are real madmen passing by here, they will be amazed by the changes in Yi Chen.

This is completely different from the usual progression of the mad, and even beyond the mad in some way, a new individual is being born.

……

【Hippocrates Hospital-Inpatient Department】

Whether it is a private ward with good isolation effect, or a multi-person ward,

The patients lying in the hospital resting all have more or less headaches, dizziness, and patients in a coma state wake up early, and even a vegetative person wakes up because of this.

After the examination of the professional team, it was found that the problem was not in the patient, but in the head caused by external interference.

This effect has even slowly spread to some apprentices and employees, and the ringing in the ears continues.

Teachers and students who are proficient in sensing have borrowed instruments to capture mental perception and found that

The source of the head discomfort is actually within the hospital.

It is the enclosed white building that is used for patient research, pathological materials, literature, and books.

Moreover, when some doctors looked up at the sky, they unexpectedly found that the clouds condensed overhead showed a circuit structure similar to that of the cerebral sulcus, and there was a tendency to evolve to the brain over time.

Not only that, but the clouds were getting darker and darker, and there was even a faint smell of death.

The increasingly bizarre situation caused many doctors to gather towards the white building, along with a woman who happened to pass by, wearing round-rimmed glasses and wearing long leather boots.

Pathology Research Center, Deep in the Death Studio.

Vice-President and one of the heads of the Department of Secret Drug Review. Dr. Vesalius was standing in a completely dry pool with four depleted bottles of "Twilight Silver Liquid" on the shore.

Although Vesalius was very painful, the sight in front of him made him not regret it at all,

As early as a few days ago, in his capacity as vice-president, it had been decreed that no one should come near this place without his permission.

Dry pool center.

A young man with a smooth skull cut open is sitting in the air,

A black biomass brain resembling a mad brain is wriggling between the cut skulls, and spiked chains are wound around it, increasing the activity of the brain with pain stimulation.

There's even an opening at the top of the brain that breathes out the breath of death.

The book emblem engraved on the back of the head is turning rapidly.

Not only that,

The muscles and organs of Yi Chen's whole body are also beating with the brain, and every piece of flesh is qualitatively changed and sublimated in this process, and the iron chains all over the body are communicating and integrating at a deeper level.

"It's the first time I've seen such a push...... How deeply this kid has established a connection with the old world, and the breath that overflows from his brain is simply an open source patient!

Completely different from the mad,

It's a brand new patient with multiple attributes, and it hasn't stopped changing, and this guy's consciousness is still using the "relic" as a medium, constantly approaching and deepening the connection with the source of the disease.

Can a three-attribute relic actually reach this level? No, it's more about himself.

What a scary guy...... If that's the case, maybe the first gentleman's question that this kid said before is not a big deal, and it is really possible for him to snatch something from the other side of the leather yard. ”
