Hearing Li Tiannan's voice, Lin Fei looked carefully left and right.

Sure enough, if you count those collapsed stone pillars, these arrangements are obviously a rudimentary Spirit Gathering Array.

Lin Fei had some doubts in his heart, could it be that the people here were all cultivators before, what did they want to do through this Spirit Gathering Array, and where did all these people go in the end?

Lin Fei had a question, but there was no one around, and even if there was, it could only be an explorer or a tourist, and no one would know the answer.

"That's right, it's like a spirit gathering array, what are they trying to do?

Although Lin Fei also knows some ways of formation, Li Tiannan, as an expert specializing in formations, should have his own unique opinions.

"Hehe, Lin Xiaoyou, if you talk about the way of this formation, I don't dare to say that it is the first in this world, and it can definitely be said to be a top-level existence. You haven't looked carefully at this circle. ”

"This magic circle looks like a spirit gathering magic circle on the surface, but if you look closely, what are the characteristics of these stone pillars?"

There was a hint of pride in Li Tiannan's voice, this way of formation was the most obsessed spell in Li Tiannan's life, so although his other spell vision was not as good as Lin Fei, when it came to the way of formation, Lin Fei was indeed inferior to Li Tiannan in some aspects.

"Oh, is there anything weird about it?"

Lin Fei carefully inspected each stone pillar, and then he found that there were these lines on each stone pillar, but due to the long time, these lines were weathered and blurred by themselves, and some of them could not be seen clearly.

At the same time, there was a small pit the size of a fist at the top of the stone pillar, and after Lin Fei looked at it carefully, he had a feeling of sudden realization.

"How is it, does Lin Xiaoyou see some doorways?"

Li Tiannan said with a smile.

"Judging from the lines on these stone pillars, this doesn't look like a spirit gathering array, there are grooves at the top of these stone pillars, which should be used to place spirit stones, this magic circle is a bit weird, like gathering spirits, but it is not entirely used to gather spirits, it seems that there are other uses. ”

Lin Fei guessed and said.

The so-called spirit stone is a strange stone between heaven and earth, it contains a strong aura of heaven and earth, in the ancient era of cultivation, many spirit stone veins were mined, countless cultivators use spirit stones to cultivate, use spirit stones to arrange formations, very wide range of uses and huge consumption.

Later, due to the lack of spiritual energy in heaven and earth, some cultivators began to consume more spirit stones in order to improve their mana and realm, and spirit stones, as a non-renewable resource, began to be gradually consumed.

At the same time, due to the lack of cultivation of spiritual energy in heaven and earth, the spiritual energy originally contained in the spirit stones also began to be emitted outward, and some of the spiritual stone deposits that originally existed began to become Fei mines, unless there may still be some in some individual extreme environments, and most of them can no longer be found.

At the age of Lin Fei, all cultivators could hardly see a spirit stone, and the spirit stone was already just a legend.

"Yes, the groove at the top of the stone pillar should indeed be used to place the spirit stone, but it's a pity that the stone pillar collapsed, and now the spirit stone is also exhausted, and this magic circle can no longer be used at all. ”

Li Tiannan said with a sigh.

As a formation master, his biggest hobby is to study the magic circle, an ancient magic circle in front of him, is of great research value to him, to see such a broken appearance now, it really makes him feel very heartbroken.

If these stone pillars were still intact, and there were a few spirit stones on the table, which could stimulate this magic circle, Li Tiannan would definitely be so excited that he would study here for three days and three nights.

But heartache is heartache, Li Tiannan still saw some clues from some clues here.

"I think this circle doesn't just play the role of gathering spirits, it should have other functions. ”

Li Tiannan guessed and said.

"What else can a magic circle around an altar do?"

Lin Fei was a little puzzled.

He felt that this should be a channel for the ancients to use this altar and magic circle to strengthen the communication channels of some gods in their own upper realm, as for the other functions, he hadn't figured it out yet.

"Lin Xiaoyou, if you look closely, there are traces of vandalism on this altar, and now it looks like an altar, I think this is just the result of the use of this abandoned stone platform by later generations. ”

"I suspect that this stone platform was used by two ancient people from different periods, and the most recent group of ancient people did use it as an altar, but the group of ancient people before them did not use it like this. ”

Li Tiannan said with a slight smile.

"Oh, what the hell is that for. ”

When Lin Fei heard Li Tiannan say this, he also began to look at this altar carefully.

At first, he just took a closer look at the stone pillars, but now it seems that this altar is the real oddity.

However, this altar was badly damaged by later generations, except for a large pit in the middle, and all around it were pitted and tattered.

Lin Fei didn't give up, still carefully checking everything around him.

Suddenly, he found that there were several primitive stones with some patterns carved on them, and Lin Fei wiped the dust off the surface of the stones with his hands and looked at them carefully.

But the more he looked at it, the more puzzled he became, the more puzzled he became, and his brows furrowed together.

"Senior Li, what did you see? Could it be that this is an ancient teleportation array?"

Lin Fei finally said his guess.

But he also didn't understand, no one in this earth world had ever seen a teleportation array, and he had never heard of a teleportation array, how could this Li Tiannan know, and where did this teleportation array teleport to?

"Yes, my guess is the same as yours, this should be an ancient small teleportation array. ”

Li Tiannan said his guess in one breath.

It is true that Li Tiannan has not seen the ancient teleportation array with his own eyes, but Li Tiannan has seen a lot of the information left by Li Tianbei, and he is very obsessed with this kind of magic array, and he wants to build one himself.

However, since the teleportation array not only consumes spirit stones, but also consumes some rarer space crystals, these Li Tiannan can't find them at all, so he can only keep these thoughts in his heart.

Now that this magic circle appeared in front of him, Li Tiannan also saw the clue at once.

"Ancient Teleportation Array?"

Lin Fei not only swallowed his saliva, this information was too shocking, where was the end of this teleportation array? Is it the legendary fairy world, or is it another interface?

Lin Fei didn't know all this, he felt a little confused, and he felt that he was getting more and more incomprehensible about this world.

Li Tiannan was also shocked in his heart, he didn't expect that he would really be able to see the real teleportation array in this earth world, although this teleportation array was seriously damaged, but in his eyes, all this was the most obsessive thing.
