Ling Tian remembered that in Jin Yong's "The Legend of the Condor Heroes", there were also a lot of introductions to the formation.

And what trapped Zhou Botong on Peach Blossom Island back then was a formation, as for the name of the formation, Ling Tian couldn't remember it.

I just vaguely remember that if you want to get out of that formation, you need to follow a special pace and way to get out.

This gave Ling Tian a different way of thinking.

However, the idea is there though. But after all, Ling Tian didn't know anything about these formations, and he didn't know how to find the exit at all.

Ling Tian didn't understand such a thing as the Five Elements Gossip, and Qimen Dunjia didn't know anything about it, so in front of such an esoteric formation, Ling Tian was completely an idiot.

"Machine Spirit, can you be more specific, your idea is too big, and the scope is too wide!" Ling Tian continued to ask.

However, the machine spirit was originally casually asked to give Ling Tian specific instructions, but obviously there was none.

Not hearing the machine spirit's answer, Ling Tian was also helpless: "It seems that you can only rely on yourself." ”

So, Ling Tian began to carefully observe his surroundings. However, in Ling Tian's opinion, the environment here was not much different from the rest of the Eternal Trial Ground, the same gray sky, and the same very strong aura.

Otherwise, the more Ling Tian walked towards the Formation Hall, the farther away he would be from the Formation Hall, and he wouldn't have found that he had entered the Illusion Formation at all.

"What's the difference?" Ling Tian said to himself.

Not to mention, after looking for a long time, Ling Tian really found that there were many differences between this place and other places.

That is, there is not a single living creature here. Although there are no animals or humans in other places, at least there are many flowers and plants, and most of them are very tall and luxuriant.

However, this thing doesn't seem to have anything to do with the cracking of the formation.

There was another difference, Ling Tian found that the huge spatial wormhole seemed to be also in this formation, and after Ling Tian was repeatedly confirmed, this spatial wormhole was indeed with this formation.

After confirming this, there was one more thing that Ling Tian also determined, that is, he was not entering this formation at all when he was taking a detour, Ling Tian didn't know when, he had already entered this formation unconsciously.

And if it weren't for Ling Tian's detour, he wouldn't have noticed that he was already in a very large formation.

As soon as Ling Tian encountered a problem, he would use his science student's thinking to start thinking about the problem: Why did such a huge formation appear here, and what was the use of this huge formation.

There is also a question that cannot be ignored, why that spatial wormhole appears in the formation.

With the direction of research, Ling Tian began to analyze the problem step by step.

First, it is easy to explain why this huge formation appeared here, this formation must be protecting the formation hall from the invasion of foreign enemies.

However, there was another question, Ling Tian couldn't figure it out, why this huge spatial wormhole was also in this formation.

According to the machine spirit's explanation, this kind of spatial wormhole is used to break through spatial obstacles. In other words, the extraterritorial evil clan back then should not have been able to enter the formation hall through a frontal attack.

Then he chose to open a spatial wormhole and directly enter the formation hall. However, the problem now is that the exit of this spatial wormhole directly enters another formation, which has no effect at all!

Moreover, Ling Tian didn't think that this spatial wormhole was an exit for mistake. In the ancient period, the extraterritorial evil clan could have the ability to make a spatial wormhole, so it was impossible to be mistaken.

Therefore, Ling Tian felt that there must be other reasons for the spatial wormhole in this formation, but he couldn't think of it for a while.

"Machine Spirit, didn't you say that the energy around this spatial wormhole should be very violent, and it is possible to suck things in the vicinity? Why can't I see any wind and grass stirring! You see, although there is no life around that wormhole, aren't those stones also motionless?" Ling Tian asked very puzzled.

The machine spirit also observed: "I really don't know this, according to the normal situation, even if we are located now, such a large space wormhole should be able to radiate, and it is impossible for us to stand here unharmed." However, this thing must be a space wormhole, and as for this space wormhole, it may have lost its original function. This is supposed to be the result of hundreds of thousands of years of self-healing in this space. ”

"No, it's not. Ling Tian said.

"If you think about it, if this thing is really a spatial wormhole, then it proves that there should be another hole in another dimension. However, looking at the way it looks here, there has been no trace of any creatures coming in for hundreds of thousands of years, you say this is not very abnormal!"

Ling Tian's words made the machine spirit fall directly into contemplation, Ling Tian's statement was very reasonable, this spatial wormhole here was very weird, except for the appearance of a spatial wormhole, there was no spatial wormhole characteristics at all.

"Why don't you go over and have a look?" Ling Tian asked boldly.

In this regard, the machine spirit wants to object, but it is not a way to spend it here all the time!

"Be careful, if there is any trouble, I will directly include you in the Ten Thousand Worlds Map. The machine spirit said cautiously.

"Uh-huh!"

Ling Tian began to slowly walk in the direction of the spatial wormhole.

In fact, Ling Tian still had a question in his heart, if this was really the spatial wormhole opened by the extraterritorial evil clan back then, then in these hundreds of thousands of years, the extraterritorial evil clan could completely enter the eternal trial ground in a steady stream, even if the low-level extraterritorial evil clan could not pass through the spatial wormhole, those masters of the extraterritorial evil clan should have no problem, just like the level of the ten heavenly kings of the extraterritorial evil clan that he had encountered before, just one of them could conquer or even destroy this world.

But why hasn't such a thing ever happened?

Walking, walking. Ling Tian finally noticed that something was wrong, although his walking speed was very slow, of course, this was also the reason for being cautious.

But Ling Tian could still clearly see that he was indeed getting closer and closer to the spatial wormhole. This has not been the case before.

Before, Ling Tian had looked for a lot of references, but the more he walked in the direction of the reference, the farther away he was from the direction of the reference.
