Periphery.

The traces of the previous battle between the Holy King Projection and Chen Xuan were still there, which reminded Jiang Chen of the earth-shattering battle that day.

Increasing his strength and speed, Jiang Chen's figure was like a ghost, running forward.

Soon, he sensed a patrol of prehistoric humans.

There are five people in total, all of whom are level seven.

And these five people didn't sense Jiang Chen, it can be seen that this formation that hides the aura can hide from this group of people, but I don't know if it can hide from the Holy King.

Taking out the map, Jiang Chen glanced at it and continued to sneak.

The underground is really boring, and although there are plants in some places, the plants are different from those on the ground, and except for a few plants, it looks barren at a glance.

Jiang Chen came to a garrison area on the periphery and observed silently.

If you want to go behind enemy lines, you must understand the habits and rules of the enemy's life.

The living habits of prehistoric humans were not much different from those of humans, but they were highly hierarchical and still feudal.

How strict is the hierarchy? After Jiang Chen's observation, if a low-level prehistoric human disobeys a high-level prehistoric human, then a high-level person can kill a low-level human at any time.

At the same time, the high-level party has great privileges, and all the women that the high-level party likes can be brought back, and the low-level women will be killed if they do not obey.

After bringing it back, the low-level party woman will not become the main house, and will always be a slave.

When the high-level party gets tired of playing, it will be rewarded to the next person.

In addition, when eating, it is also the first to eat.

Take, for example, a hundred people eating.

These 100 people are the upper, middle, and lower classes, the upper class eats first, and then the middle class eats when they are full, and finally there is not much left, and then the lower class eats.

This is the most primitive rule of survival, and they have been preserved to this day.

Taking out the map, Jiang Chen looked at it.

It takes nearly a few months to get from the periphery to the depths, and half a year to get to the center.

Of course, this is based on Jiang Chen's speed.

Jiang Chen naturally didn't have so much time to waste, and he believed that prehistoric humans must have had a way to quickly reach the depths and the heartland.

Pick up the map and look closely, there are a number of small red markers and small dark black markings on the map.

Jiang Chen didn't understand what these marks meant, but he felt that they should be the unique way of prehistoric humans.

Roughly calculated, if this is the way to go, it would take nearly a day to get from here to the red-marked area.

Jiang Chen hurried towards the red mark, and he arrived here a day later.

In front of us is a building made of boulders, and people come and go, just like human stations and airports.

Since there are ordinary people and masters here, it is very chaotic, and Jiang Chen easily blends in.

After coming in, Jiang Chen was not in a hurry to leave, he hid to the side and observed.

After observation, he found that there were many large circles with white glows in front of him, and there was a stone tablet in front of the circle, and the stone tablet said the destination, and a group of people threw a black stone at the guards and then entered the circle, and disappeared in an instant.

Immediately after, another group of people appeared in the circle and walked out.

Seeing this, Jiang Chen understood that this was something similar to a teleportation array, which was the mode of transportation of prehistoric humans.

And the black stone, which I don't know what it is, should be their currency in circulation.

If we calculate it now, it will take two or three days at most to get from the periphery to the center, and these two or three days are wasted time rushing to the mark.

Jiang Chen left here and went outside to knock a civilian unconscious, then took the black stone from his body, and took off the black robe he was wearing, covering his face, black knife and black armor.

He held the black tassel gun directly, after all, holding a weapon would not attract attention, the only thing that could attract attention was his eyes and skin color.

Preparing everything, Jiang Chen came back again, then blended into the crowd, threw a black stone and walked into the aperture.

After entering the aperture, Jiang Chen felt that his eyes were dazzling, and the scene in front of him changed.

In an instant, he came to another place.

I have to admit that in the use of Reiki, human beings are far inferior to prehistoric humans!

Prehistoric humans have done so much in transportation, let alone exercises!

No wonder, the human grandmaster can't even beat the half-step grandmaster of the prehistoric human, this ...... It's the gap!

Walking out of the aperture, Jiang Chen left with the crowd.

He glanced at the terrain outside, then found his place.

He's already in the depths.

There are not only red markings, but also many black markings.

Jiang Chen guessed that if he wanted to go to the center, he should not be able to go to the red mark, and he had to go to the dark black mark.

After all, the map shows the central area...... It's all dark black markings!

However, Jiang Chen was not in a hurry to go to the center, he had to survey the depths first.

Compared to the periphery, the depths of the underground are much more upscale.

There are obviously more buildings here than on the perimeter, and they are all stone buildings, although there are many civilians, but more are masters with weapons.

On the street, the ninth level can be seen everywhere!

Jiang Chen was extremely surprised, the depths were like this, what was the center?

Prehistoric humans were so strong, how did humans win that war at that time? Jiang Chen really couldn't figure it out.

As he walked, Jiang Chen saw a wanted notice on the street.

It is an ancient text, but Jiang Chen, who has studied Qimen Dunjia, can understand it, and the person wanted is the small leader of the prehistoric human rebels.

At this moment, Jiang Chen suddenly realized.

It turns out that the prehistoric human side was not peaceful, and there were wars between each other! Back then, the Holy King did not participate in the war with the humans, and must have been delayed by the war here.

That's a good thing for humanity, because the enemy of your enemy is your friend!

However, it is not a good thing.

For example, if the Dragon Alliance has a civil war and other alliances come to make trouble, it must be unanimous with the outside world first!

For prehistoric humans, humans are still outsiders after all.

There are many restaurants and post stations in the depths, and Jiang Chen can hide his breath, so he became a thief behind enemy lines and stole a lot of currency.

He came to a restaurant to eat, and only his mouth and nose were exposed.

Not to mention, I don't know what kind of meat it is.

"Did you hear that? Two days later, the Holy King is going to recruit relatives for the emperor! ”

"Really? Although the Holy King has three sons, but only one daughter, that is the pearl of the Holy King's palm, and the Holy King is finally willing to marry? ”

"Who knows, the notices have been posted anyway, and I also heard from a friend who brought here from the center to do business!"

Hearing the conversation on the table next to him, Jiang Chen was stunned.

Diji, on the side of prehistoric humans, is also the meaning of princess.
