It was only at this time that the first director of the Hidden Bureau realized that this place was more serious than he thought.

On the one hand, he asked people to urgently rescue the seven wounded, and on the other hand, he sent people to block the entire uncursed road, and he was not allowed to enter without orders.

After a lot of work, two of the wounded finally returned to normal and began to tell the specifics of the operation.

Of course, the content is top secret and has not been declassified until now.

Except for the upper echelons of the Hidden Bureau, no one knows what happened to that exploration.

I couldn't help but feel a little sorry when I saw this.

If you think about it carefully, the experience of those more than 100 masters under the uncursed path must be extremely incredible, even the kind that subverts the worldview.

Otherwise, the Secret Bureau would not have refused to lift the ban until now.

Anyway, as far as I'm guessing, it shouldn't have anything to do with revenant zombies.

Because the Secret Bureau is ready to disclose the existence of the revenant and zombies, there is no need to keep a single exploration record of the year a secret.

After this incident, the Hidden Bureau stopped exploring the unspelled path for a while.

Until the national power of Middle-earth is getting stronger and stronger, the masters of the hidden bureau are like clouds.

Even the demon suppression army has expanded to more than 12,000 people.

So he began to gradually send people to explore step by step.

Because of the tragic lessons that happened back then, they only dared to explore near the uncursed road, and never went too deep, so the demons and demons such as the Yellow Spring Unsinkable Corpse, the Human-Faced Demon Moth, and the Styx Water Ghost were gradually explored.

According to later explorations, the Bureau of Secrets divided the Unspelled Road into three parts.

The first part, and the relatively safe part.

It's about 300 to 700 meters underground.

Follow the unspelled path passage into it, and you will soon encounter an underground river.

The river stretched as far as the eye could see in the darkness, and it was not known where it was going.

This is the famous River Styx.

Downstream along the River Styx, at a depth of about three hundred meters, there will be a vast underground space.

This is known as the first section of the uncursed path, also known as the life and death section.

Roughly speaking, in this place, the top is life, and the bottom is death.

The range of the life and death section is extremely large, according to the sound wave detection, it is about 300 kilometers in radius.

In fact, this data is very inaccurate, because the terrain of this underground space is extremely complex, and there are many echoes caused by acoustic wave detection, so there are certain differences in imaging.

Moreover, over the years, the exploration team of the Hidden Bureau has only explored the radiation range of less than fifty kilometers at most, and the simple topographic map in the data refers to this place.

Because this is an underground world, and the yin qi is extremely heavy, it has given birth to a lot of extremely powerful demons and evil spirits.

The famous Yellow River Unsinkable Corpse and the Styx Water Ghost both like to roam this place.

In order to figure out the distribution of evil in this 50-kilometer area, the Secret Bureau does not know how many lives have been paid.

The second segment is called the demon segment.

Probably after a depth of 500 meters.

At a position of five hundred and thirty meters, the rushing River Styx is bound by the topography, forming two tributaries.

One of the tributaries runs to the capital, and the other runs through the eighteen underground spaces, the famous eighteen layers of hell.

There are masters in the Hidden Bureau who are not afraid of death, and they have explored these two tributaries respectively.

However, due to the accident of the last exploration, the masters of the Hidden Bureau did not make a big move, but adopted a team infiltration mode of three or five people.

As a result, the casualty rate of each expedition reached more than fifty percent.

This is also the only fixed passage into Middle-earth other than the natural retrograde passage.

If the era of the end of the law comes, the curseless road will definitely become a battleground for soldiers.

However, the third paragraph is recorded in the source as an unexplorable paragraph.

Because after bypassing the capital and the eighteenth layer of hell, the closer you get to the ground, the more chaotic and crazy people's minds will be.

Just like a resentful soul affected by resentment, it will gradually become insane and violent, and there will be symptoms of visual and auditory hallucinations.

You must know that the soul of an exorcist is extremely powerful, and it is basically impossible to be disturbed by hallucinations.

If this happens, it means that there is something in the deepest part of the uncursed path that can affect the soul.

It's worth mentioning that it's not just the Demon Suppressors in Middle-earth who are affected.

Even the Eighteenth Layer of Hell will be polluted by the soul from time to time.

Well, it is recorded in the sources that this phenomenon is called soul pollution.

Even the deepest part of the eighteenth layer of hell, such as the City of Vain Death, the entire city has become a polluted disaster area, and even the ghost soldiers of the capital will forcibly disperse the souls of the other party when they see it.

It's a pity that because of the existence of soul pollution, the Hidden Bureau's exploration of the unspelled path has come to an end.

And the inability to explore section has also become the most mysterious section of the uncursed road.

Except for the seven exorcists who were lucky enough to come back alive that year, only the high-level of the Secret Bureau knew.

After reading the introduction to the uncursed path, I opened the rest of the folders and carefully analyzed and scrutinized.

Soon I had another discovery.

The deepest soul pollution of the Uncursed Path is gradually expanding outward every year.

With each expansion, the living space of the eighteen layers of Hell and Xudu will be compressed a little.

According to the information obtained by the Secret Bureau, in about three hundred years, there may be no place for Xudu and the Eighteenth Layer of Hell.

The Prison Masters of the Eighteenth Layer of Hell were also aware of this problem, so they had to start planning for the future now.

As for what to do?

Of course, it was the expansion of the Chaoyangshi.

Soul pollution compresses our living space, and we have to compress the living space of the living.

Originally, the Yang World was not suitable for the survival of the revenants during the day, but there was no way to do it.

The space for his own life is about to be compressed, and he can only move forward in the sunrise world.

It's great that everyone should be a turtle with a shrunken head, hiding it during the day, and then coming out to jump at night.

But later, the advent of the era of the end of the law gave Xudu and the eighteenth layer of hell a chance.

Because after the arrival of the end of the Dharma era, the yin and yang breath of the yang world will gradually change, and this change will block part of the sun's rays.

This also means that after the end of the Dharma era, demons and spirits can also appear during the day without fear of being illuminated by the sun.

This discovery surprised the Ten Palaces of Yama in the capital.

They immediately inflated their ambitions, and from the very beginning, secretly lived in the middle of nowhere, daring only to appear in the middle of the night, and changed to conquer Middle-earth.

As long as Middle-earth is killed, this land can rebuild the capital.

When the time comes, the underworld will be given to those who don't know what to do.

I won't play with you anymore.

Therefore, with the advent of the end of the Dharma era, the relationship between Middle-earth and Xudu and the eighteenth layer of hell has become more and more tense.

To put it bluntly, it's all about survival.

I was a little surprised when I saw this.

I am also more curious about the so-called soul pollution deep underground.

What is it that makes the powerful Yu Du tolerate the erosion of his territory a little bit, and he can't even resist it?

And from this point of view, the contradiction between Middle-earth and Xudu is afraid that it will have to fall on the strange soul pollution.
