In the dark, Liu Pan hit a wall.

This is a wall between the void and the real, which can be seen with the naked eye, can be felt by the palm of the hand, and even the divine consciousness and spiritual power can easily touch it.

However, there is no way to go deep, and all perception is only superficial.

Like a projection screen, no matter how colorful the picture played on it is, what can be touched from the outside is only that layer of temperatureless background curtain.

Liu Pan's perception is surging wildly, however, as his perception continues to increase and spread, his originally numb zombie face has become more and more devoid of temperature.

Can't perceive! Can't probe! Can't go deeper! The feedback of perception made Liu Pan's brows furrow slightly.

The barriers of this world are so isolated that even the perception of a near-god is completely incomprehensible!

What is the situation? Liu Pan was depressed. Liu Pan has a strong confidence in his own perception, which is also his biggest reliance all the way to this day.

However, at this moment, this powerful perception that can see through everything in the world and see through the world is completely useless in the face of the barriers of this world!

Isn't this almost God's perception? If it is God's perception, how can it not be perceived and probed even a small "wall"?

Liu Pan closed his eyes, his mind was highly concentrated, and his perception was hovering back and forth at the critical point between "inside the world" and "outside the world", but in reality, he failed to perceive the existence of the "wall" at all!

Even, if it weren't for the touch of his palm, his spiritual power and divine consciousness were blocked, he wouldn't have felt that there was such a wall in front of him at all!

What the hell is going on? Liu Pan was very confused, this is a bit too unbelievable.

Since it is something that can be touched by reaching out within the Tianfeng Continent, is it possible that it has to be classified as "outside the world"......?

The perception was further enhanced, and immediately, a blurred spot of light appeared in Liu Pan's "field of vision", but the perception of the world barrier was still zero. As if it really didn't exist!

In an instant, this thought flashed through Liu Pan's mind, however, if the palm of reality can be touched, all perceptions such as divine consciousness and spiritual power will also be blocked, how can this not exist?

The perception was enhanced to the extreme, and then gradually weakened to "within the world", and then strengthened again and again, and after several times, Liu Pan's thoughts were a little confused.

Regarding his own perception, Liu Pan has no doubts. Even Liu Pan believed that in the entire Tianfeng Continent, as long as it was something that appeared in his perception, there was no secret to him.

But the barrier to the world in front of him is not only the perception of "within the world", but even the perception of "outside the world" cannot be detected in the slightest, which is really beyond the understanding he originally thought.

Originally, according to what he learned from many ancient historical books, Liu Pan felt that the world barrier should be similar to the formation to some extent.

In this way, with his near-godlike perception, Liu Pan felt that he might be able to see some clues from it, and even look for traces of the flow of certain energy on the barrier of the world, so that he could leave this world through the barrier without breaking through the void.

But in reality, he really never thought that his perception would not even be able to perceive and probe the cortex of the barrier of this world.

If it doesn't belong to the inside and outside of the world, can it belong to other universes? It can belong to other universes, how can this appear in this universe, and even constitute a world barrier in the Tianfeng Continent?

His thoughts were stirring, even as a fantasy author, Liu Pan felt that his brain was a little inadequate.

Moreover, the contradiction of this world barrier is far from being like this, more directly, there are extremely real things in this barrier!

When I opened my eyes, it was already evening, and the light visible to the naked eye, little by little, began to light up in the curtain of the world barrier, it was the stars!

Not only the stars, but also the sun and moon in other parts of the world barrier, and even light and heat coming from them!

Perhaps, for the rest of the Tianfeng Continent, the sun, moon and stars in the sky are real, however, the perception that Liu Pan has is always reminding him that the world barrier is just a "curtain"! The sun, moon and stars are only in this "curtain", not in that distant void at all!

But is this normal? From an imperceptible "curtain", the essence of the sun and the moon is revealed, and there are even various other energies such as light and heat, which is unbelievable from any angle!

Or is this really related to the universe? The theory of the spatial dimension? It is difficult for creatures in the lower dimensional space to understand the various things that exist in the higher dimensional space? The root of this world barrier is in the cosmic space of the higher dimension, so it cannot be understood?

Or, is it because of the rules of the universe? This world barrier really exists in the cosmic space of this world. It's just that the Tianfeng Continent is too decayed, and the rules and rhymes are incomplete, so his perception can't read the rules and rhymes contained in the world barriers?

There were all kinds of thoughts mixed in his mind, Liu Pan was thinking about it, and at the same time made various attempts, and even he took the psychic artifact from Li Song's hand and tried to communicate with the Open Heaven Axe Spirit, but the ending was still fruitless.

You can touch, you can see, you can get rid of these things, and all the other methods will not work at all against the Heavenly Barrier. Even if he used all his strength to bombard the Heavenly Barrier, Liu Pan's perception could not feel the slightest trace of energy fluctuations from the Heavenly Barrier.

For two days and three nights, Liu Pan was silent for a long time against the Heavenly Barrier, and he also listed all kinds of possibilities for the existence of the Heavenly Barrier as much as possible, but in the end, there was still no gain.

It may just be possible, and even if it is listed, there is no way to verify it.

The stars faded, and the barrier of heaven turned blue and gray, and there was no doubt that it was another day of rising sunrise.

Liu Pan was helpless, exhaled, and all kinds of thoughts in his mind were thrown away, and said: "Let's go, go and see the top of the mountain, this heavenly barrier is beyond my cognition, and I won't gain anything if I stay any longer." ”

Li Song was silent when he heard this, and Ye Qing opened his mouth to say something, but in the end, he didn't say anything. But undoubtedly, there was a slight look of disappointment in the eyes of both of them. Perhaps, in their opinion, as Liu Pantianwalker, this trip will inevitably have some unexpected insights and gains, but in reality, nothing special happened.

Liu Pan could roughly guess what Ye Qing and Li Song wanted, but he didn't pay attention to it or explain it, he didn't have the heart to do anything superfluous and unnecessary now.

Looking ahead, apart from that madness, maybe the only hope is that one is possible......

Going up along the wall of heaven, Liu Pan's original plan was to explore the barrier of heaven in the belly of the mountain and then go outside the mountain to climb to the top of the mountain, but in reality they misestimated the ability and determination of those predecessors who came here to see the sky.

From the belly of the mountain along the barrier of heaven all the way up, the predecessors had already dug a relay to dig a passage to the top of the mountain, except for the final exit was sealed by ice, the rest of the effort was almost effortless.

More than 300 meters of solid ice is nothing compared to the more than 800 meters dug from the foot of the mountain into the belly of the mountain, and in just one day, the three of them reached the top of the mountain from the belly of the mountain.

The morning sun rises in the east, and even the extremely icebergs that have not melted for thousands of years seem to have a little warmth. The world is vast, and the vast and boundless North Plains are dyed with orange and red, and the incomparable shock makes Liu Pan and the three of them silent, and the original depression is also diluted a lot by this vast scene.

Liu Pan leaned back against the Heavenly Barrier and looked up, his line of sight was extremely blue nothingness, although he couldn't see any arc of the Heavenly Barrier, but Liu Pan, who already had a macroscopic consciousness, naturally wouldn't think that the Heavenly Barrier was a vertical wall.

"Crystal ball", how did such a world pattern come into being?

Liu Pan's mind was at a loss, and there was a "Big Bang" origin theory in the universe where the earth is located. That is, the universe was born from a big bang. It is formed by the expansion of a dense, red-hot singularity after a big bang.

Liu Pan has a little understanding of the theory of the Big Bang, and there is indeed some truth to it. However, the universe in front of him where the Tianfeng Continent was located did not look like it had originated from an explosion at all. The existence of the "crystal ball" world also subverts Liu Pan's original three views on the world.

"Crystal Ball"?Perception is improved from "outside the world", looking at the blurred spots, Liu Pan suddenly gave birth to some strange thoughts.

Isn't the "crystal ball" a natural formation? In this cosmic world, there really is a god who can penetrate the heavens and the earth, and it is he or they who have created these countless crystal ball worlds? But why is that?

Thoughts are flowing and boundless. I don't know how long it took, Liu Pan suddenly had a mist in front of his eyes, and then Liu Pan was shocked, retracted his thoughts, and pulled the brim of his hat to block the ray of sunlight that was scorching his cheeks.

Turning his head, Liu Pan saw Ye Qing and Li Song staring at him with strange expressions on his face, and he couldn't help but be a little funny while being embarrassed.

Obviously, I was still worried that I couldn't find a way to leave this world, and this thought was thinking about the origin of the world of this universe.

Stretching out his hand and rubbing his forehead, Liu Pan quickly suppressed his thoughts and reined in his thoughts, and said, "Let's go, it's useless to stay here, continue to hurry, we still have a lot of places to go." ”

When the words fell, Liu Pan did not delay, stepped forward, and then slid down the hillside to the foot of the mountain.

Standing still on the smooth and flat ice, Liu Pan was stunned, and then looked at the ice under his feet and looked a little weird, for no other reason, but at this moment, a bunch of strange questions unconsciously popped up in his mind: gravitational force? Does this law apply in this universe? The gravitational direction of this "crystal ball"...... Could it be that it didn't come naturally?
