In the dense and blazing primeval forest, the air was shouting because of the geistes on the periphery, even though it was already a full mile away from the ghost wall.

The four of them marched forward one after the other, and to be precise, they were heading towards the depths.

The scope of the geist wall is extremely vast, with a radius of dozens of miles, all of which are surrounded by them in a circle, and the number of geists is even more terrifying, at least hundreds of millions.

However, after passing through the first barrier of the Spirit Wall, the distance in the middle of the section, the four of them did not find any signs of life, and there were no energy fluctuations.

It's a terrifying thing, especially in a land like this, with so many necromantic lands, where have all these things gone? What are they doing now? Did they all disappear out of thin air?

The more the four of them walked inside, the more strange they felt, there was really nothing, the whole forest seemed to be empty, there was nothing!

"It's so strange!" Wu Di underestimated as he walked.

What makes Wu Di feel even more strange is that in such a large wood, in addition to the absence of undead, there are not even corpses, according to common sense, this is a very strange thing, such a large area, even if these aborigines are killed, there should be corpses or bones, right?

But looking at it now, not to mention the bones around, there are not even many fallen leaves, as if they have been cleaned by some force, it is extremely clean, such a scene in this forest can only be said to be weird.

However, this is not a clean place, and the four of them glanced at each other, and they all saw the doubts and worries in each other's eyes.

However, they had all walked such a long distance, and the four of them didn't have much to say, so they could only go inside.

After walking for about a mile, they saw that in the distance, there was a huge black ball, as if it had grown out of his younger brother, encompassing nearly three or four miles of the realm.

This is an extremely huge black ball, the diameter alone, may be more than two or three miles, only the upper part of the air is exposed, the entire earth boundary is included in it, it is very black, it is also huge, like a bowl upside down, with the naked eyes of mortals, you can only see this black ball, you can't see what is in this black ball, you can't feel any breath.

Such a huge black ball, black and deep, as if it could swallow some, like the entrance to the abyss, even the light shining through, it was impenetrable, as if it was absorbed by the black ball.

Far away, the four of them clearly felt the rich dead air coming from the black ball, this dead air was as dignified as a tide, very condensed, I don't know how many dead souls there are, in order to condense such a dignified dead air.

And these dead breaths suddenly seemed to be substantial, and the four of them all felt that their shoulders were sinking, as if they were carrying heavy objects, and they all walked much more slowly.

There was a strong rancid smell in the air.

It wasn't until he arrived here that Wu Di knew why the periphery was so clean, it turned out that those aborigines, to be precise, the corpses of those aborigines, were all gathered here, and outside the black ball, they were disassembled, and with bone blood, outside the black ball, an extremely large and ancient magic circle was arranged.

This is a magic circle, not a ban, but it can also be used to protect one side, but the magic circle is recorded in the book, it has been extremely rare in the last century, I didn't expect that in this century, there can still be such a huge magic circle.

Wu Di looked at it, his face sank.

These knowledge are all learned from the knowledge imparted by the dead wood, which is also some unpopular knowledge for learning the ban, for those who learn the ban, there may be some use, but I didn't expect it to come in handy today.

It's just a pity, even if it's Deadwood, there is not much to know about the magic circle that has been close to extinction in the last century, let alone know what kind of magic circle it is.

But needless to say, just from this scale, this spirit, how could a magic circle forged by using the bones and blood of all living beings within a radius of ten miles be weak? Wu Di estimated that this magic circle, I'm afraid that it is an ordinary Savage Soul Realm powerhouse, and it may not be able to pass through, right?

This is just Wu Di's speculation, Wu Di's current eyesight is not much different from that of a half-step Savage Soul Realm powerhouse.

I don't know what method this used, when they were in the outside world, this black ball couldn't be seen at all, until they came here, and when they were only more than two miles away from the black ball, this huge black ball appeared in front of them as if it appeared out of thin air.

Maybe it's the hidden function unique to the messenger circle.

It was Wu Di who could only think of this answer, after all, he didn't know much about the magic circle.

"Boss, look!" At this time, Zeng Senmiao suddenly spoke up and pointed to a place.

Wu Di heard the words and looked at his fingers.

A group of twelve skeletons in black armor and carrying broken weapons were walking along a specific road, and the reason why it was said to be a specific road was because the ground, which had been walked on for an unknown number of times, had actually walked out of a road.

Wu Di couldn't help but think of what an earth writer said when he was on Earth at that time: When there are more people walking, there will be a road.

The situation is similar here.

Wu Di's eyes narrowed, and he secretly said in his heart: It seems to be a well-trained team!

He followed the road that the team was taking, looked all the way, and suddenly found that there were not many roads like this around the huge black balls, but dense, square and orderly, surrounding the black balls.

"The 100-meter team, just the skeletons patrolling outside this black ball, I'm afraid they are no less than thousands!" Wu Di narrowed his eyes and came up with an approximate number, this is just an approximate number, it is already so amazing!

Wu Di looked at it carefully.

He spotted one of the skeletons, this was a skeleton similar to the others, the clothes on the body, I don't know what period of clothes, had been corroded and tattered, and the patterns that were vaguely left showed an extremely ancient atmosphere, not like the style that should have been in this century.

Wu Di couldn't help but stare at him.

How could he be unfamiliar with such a scene? Wasn't this the terrifying undead he had seen last time when he was in the Eternal Realm?!

It's no wonder that Wu Di would think of somewhere, it's really too similar, they are all the same skeletons, wearing ancient clothes that are not this century, and the wedding is full of life.

Wu Di couldn't help but turn pale, and when he thought of the skeletons in the Eternal Primordial, Wu Di thought of the scenes in the mysterious mine cave and the sea of blood.

In the sea of blood, Wu Di clearly saw a lot of coffins, these coffins have a strong dead air, obviously there is something in it, could it be that these coffins have individual things, some are scattered here?

If that's the case, it's terrible.

Wu Di continued to look, these skeletons were like living people, with their heads raised and chests held high, strutting forward, looking majestic and high-spirited.

In their eyes, there was a dark blue ghost fire burning, and it was these two ghost fires that made these skeletons seem to be injected with life.

Wu Di guessed that perhaps it was because of the existence of these ghost fires that these skeletons came to life.

The aura on their bodies is also extremely strange, neither like the fluctuation of human cultivation, nor like the fluctuation of the aura of ghosts, nor like the ferocious aura of beasts, which is unique and does not belong to any column, and this aura also gives Wu Di an extremely ancient feeling, as if it is a cultivation system of the last century.

That's right!

"Could it be that this is an independent space that belongs to the last century?" Wu Di couldn't help but guess that everything here made him feel as if he had traveled through time, but the facts told him that this was not the case.

Wu Di, who is good at opening up space, naturally knows that if he travels through time and space, the space around him must be extremely unstable, where will it be so calm, the outbreak of space storms is light, and it is very likely that there will be a spatial collapse, in that case, who will set up camp in such a place?

If this is the case, then there is only one explanation for the past that reveals the mystery of the place, which has been handed down from the last century.

Either the owner of this place is the existence of the last century, or there are people who are proficient in the knowledge of the last century.

No matter which one it is, it is very unfavorable for Wu Di and his party, because they don't know much about the things of the last century.

"The combat power of these skeletons should be about the same as that of the cultivators of the Barbarian Body Realm Fivefold, but I don't know if they are undead or not, if they are, then even if they are Barbarian Realm Ninefold, they may not be able to get out. Wu Di groaned and said to the three people around him.

"This place is extremely dangerous, among this black ball, it must be the location of Fengdu, which has been in a uproar recently, it is unpredictable, I don't worry about you. Wu Di truthfully told the three of them about the worries in his heart.

"Boss, we can do it, take us there!" Zeng Senmiao and the three of them all changed their faces when they heard Wu Di's words, they naturally knew that Wu Di was for their good, but if they didn't dare to move forward now because they were afraid, what was the difference between them and deserters?

"No, you can't go, I can only go here alone!" Wu Di's face was resolute, obviously he had already made a decision, this time, he had to go in alone.

"Boss!"

"Don't say it, this is a military order, you can't violate it!" Wu Di said in a deep voice.

When the three of them heard this, although they were unwilling, they could only receive their orders.

"Yes, boss!"
