Luo Yuan glanced at the experience, and was in a good mood, the upgraded experience had arrived: 197520/307200, as long as he completed three or four more tasks, he would be able to upgrade one level more. It's a pity that the "water dragon", that is, the water giant beast, is not a perfect kill, and only has basic experience, otherwise the experience will be 19,200 points more.

However, this task was basically picked up for nothing, and it didn't take much effort for him at all, but he didn't care.

At this time, the water surface that had just calmed down below began to swell again, and the water waves were agitated and boiling, and schools of fish, large and small, converged on this side like a tide, each of which looked hideous and vicious, and from the top down, the whole lake seemed to be dyed with ink.

The golden giant bird was extremely miraculous, especially the three tail feathers that glowed with blue light, which impressed Luo Yuan, Luo Yuan originally thought that he would fish up the half-cut tail feathers floating on the lake to identify it and see if it was useful, but when he saw this scene, he immediately wisely chose to give up.

Whether in the air or in the water, his ability to move is greatly reduced, it is simply the best target, if you don't pay attention, you may be in danger, in this wilderness, there are many such magical materials, and there is only one life, if you don't force it, he doesn't want to risk his life.

……

Luo Yuan beckoned to the mutant who was hiding in the bushes not far away.

The mutant hesitated, and after a long time, he hunched over and crawled towards her with a wary face.

Luo Yuan couldn't cry or laugh, if it really wants to be unfavorable to you, it is useless for you to be vigilant.

"Sit!" Luo Yuan said while demonstrating the posture.

She blinked, and instead of reacting, she took a few steps back vigilantly.

Luo Yuan thought that she didn't understand, and patiently demonstrated a few times.

The mutant looked hesitant, and after a while, she finally slowly learned Luo Yuan to sit on the branch, she didn't sit down, her buttocks were weakly attached to the branch, her whole body was tense, and she only did it for a few seconds, and then she looked around frequently, looking nervous.

Luo Yuan glanced at her, and immediately understood, mutants have lived in the wilderness for too long, and the constant alertness to danger has long become her instinct, and this kind of human relaxed posture, in the face of danger, whether it is choosing to fight or escape, will be a beat slower, which obviously makes her extremely insecure.

Luo Yuan didn't force it, he opened his backpack and threw a bottle of water over.

The mutant hurriedly took it, and at the same time changed the sitting posture to squatting, she glanced at Luo Yuan, and saw that he did not continue to correct, she seemed to be relieved, and her whole body relaxed.

Luo Yuan didn't bother to care about her, took out the map from his bag, and carefully studied the next journey, as well as the sea route at that time.

Compared to the land route, you can walk freely, as long as you reach the destination at the end, but the sea route does not tolerate the slightest error, the sea is not only wide, but also has no reference.

He had to follow the planned direction so as not to miss the pre-planned islands on the way that could accommodate short breaks and supplies.

The mutant looked at the bottle, she had seen Luo Yuan's movements, and had some experience, this time she did not bite the plastic bottle directly, but tentatively twisted the bottle cap, and found that it could indeed be rotated, her expression was suddenly excited, she quickly spun it a few times, and after a while, the bottle cap opened.

She shook the plastic bottle gently, learned from Luo Yuan, opened her mouth, lifted the plastic bottle, began to pour it, and drank the bottle of water in one go.

Then she secretly glanced at Luo Yuan, and saw that he didn't pay attention, so she secretly hid the plastic bottle behind her back.

It's a pity that there is nothing to hide from Luo Yuan's perception, seeing this, he was speechless for a while, worried about the IQ of the mutant, thinking that even if you want to hide, there is no place to hide, when you have a bottle in your hand, it is not clear who took it.

Of course, he doesn't mind a plastic bottle either.

……

After a short rest, the two of them hit the road again, and an hour later, the water began to fade gradually, and after turning over a mountain peak near the lake, the road became a jungle familiar to Luo Yuan.

The heart that had been tense finally relaxed a little.

As a terrestrial creature, such a bad environment makes him feel safe!

Guizhou is mountainous, with high mountains and deep valleys everywhere at a glance, steep mountains, some peaks, and perennial smoke.

These places are extremely rare even before the end of the world, and because of the karst landform, there are many karst caves and sinkholes here, but Luo Yuan has no interest in exploring and hurried all the way.

He was on his way when he suddenly felt his brain dizzy, and then a tiredness rose from his heart.

His physique is as high as seventeen points, plus the bonus of the earth's pulsation, as long as he stands on the ground, his physical strength is endless, and the comprehensive physique is as high as a terrifying 23 points.

He immediately realized that something was wrong and quickly stopped to check the system.

Just by looking at it, his face changed slightly, and before he knew it, the "four-dimensional brain" had jumped to 2%

"Four-Dimensional Brain"

"Four-dimensional depth: 2%

"Effect: 1: Prediction for 2 seconds; 2: Four-dimensional visual senses; ”

"Comment: The four-dimensional world is colorful and colorful, but mortals cannot look at it directly, because they only have a rudimentary brain. You who have already opened the four-dimensional road are destined to be extraordinary. ”

Seeing that it was a four-dimensional brain, he was slightly relieved, and had a little expectation, this time it came out, and the prediction showed a huge effect, and the effect was exactly like the infinite reading file in the game, which benefited him a lot, and he almost died several times, he relied on foreknowledge to avoid danger, and finally killed a strong enemy.

But what exactly are these four-dimensional visual senses?

Literally, it should be related to four-dimensional vision, and it is to analyze the four-dimensional world!

Four-dimensional vision has always been useless except for giving his brain a lot of junk information to make his brain think sluggishly, once for a while, he was preoccupied, the pressure was huge, in order to alleviate the impact of this information from the four dimensions, he had to do everything possible to find the heart of wisdom, to improve intelligence.

And even now, thinking and vision are still the biggest hidden danger in his heart, and they may explode at any time.

Through the strap on his forehead, Luo Yuan vaguely seemed to have "seen" some incredible scene, but because of the obscuration of the bandage, it was vague and he couldn't see it clearly.

His heart fluttered, but before that, he had to find a safe place.

It wasn't long before he was at the foot of a cliff and found a place to live for the night.

This cliff is full of caves, one after the other, dense, a narrow stone path shaded by woods and grass, connecting these caves, Luo Yuan thought he had found the residence of the intelligent race when he first saw it, but when he got inside, he found that this was the remains of human beings.

Looking at the enamel dishes that have not rotted after several years, it is clear that this place was inhabited by humans before.

There are many ethnic minorities in Guizhou, some tribes live in the high mountains, the transportation is inconvenient, isolated from the world, it is difficult for the secular civilization to affect here, some tribes are even in the primitive matriarchal society, Luo Yuan found the cave group, obviously one of them.

Today, the people here are estimated to have died a long time ago, leaving only caves, which still exist.

For more than ten minutes, Luo Yuan checked the potential safety hazards here, and began to take off the straps regardless of the mutants nearby.

In an instant, Luo Yuan's gaze instantly became misty, exuding a peculiar look.

"So it's a four-dimensional world!"

A new world unfolded before his eyes, and he stood up unconsciously, and at the same time, an aura of detachment and independence from the world permeated him.

The astronomical information from the fourth dimension flashed through his mind, and he had a feeling of enlightenment, the essence of the world was unveiled in front of him, and the miraculous thing was that with the opening of the four-dimensional visual senses, this information did not cause the slightest blockage in his brain.

"It turns out that my previous guesses about the four dimensions are wrong, this is the real four-dimensional world, it turns out that we all live in the four-dimensional space." He sighed, and a kind of realization was born in his heart.

Originally, in his understanding, the three-dimensional can look down on the two-dimensional, if there really is a two-dimensional life, then the two-dimensional life has no secret to the three-dimensional life, and when you see its skin, you can also see its heart, its brain.

Anything, no matter how secret it is hidden in the second dimension, even if it is buried in the ground and swallowed in the mouth, it is clear in the eyes of three-dimensional creatures.

Then according to the same logic, four-dimensional vision should also be able to look down on three-dimensional.

However, Luo Yuan found that this logic is indeed correct, and in fact it is true, but due to the different definitions of the concept of dimension, the four-dimensional vision does not have the effect imagined.

Just as the three-dimensional world has no absolute meaning of two-dimensional life, Luo Yuan found that the four-dimensional world also does not have absolute three-dimensional life, in a sense, not only the earth's soil, stones, and people are also four-dimensional, but the fourth dimension is pitifully short, almost negligible.

However, it was this short and pitiful dimension that made it impossible for him not to look down on the three dimensions as he did for the two.

The point is zero-dimensional, the line is one-dimensional, the surface is two-dimensional, and the three-dimensional space is the environment of human existence, which is the three-dimensional environment we are familiar with. And the fourth dimension adds another dimension, before there is no "four-dimensional visual sense", the fourth dimension can only speculate out of thin air, all he can see is a clump of changing colors, and only at this time, this fourth dimension is revealed in his eyes.

Luo Yuan found that this was not the time that humans usually understand, nor was it some strange and unpredictable existence, but the warp of space.

Just as the two-dimensional plane is distorted to form a three-dimensional mountain valley, a slender two-dimensional paper strip is twisted 180 degrees to form a three-dimensional Möbius ring, and the three-dimensional space distortion can also form a four-dimensional Klein bottle.

The warp of space is the fourth dimension that the four-dimensional world has added.

However, everything has gravity, and gravity causes space distortion, so in the three-dimensional world, people also have a very weak spatial warpage, and there is no strict limit in four-dimensional three-dimensional, the difference lies in the size of the spatial warpage, and the existence of the four-dimensional sensor.

Subsequently, Luo Yuan thought of the pseudo-four-dimensional life Xu Zhiqiang.

His previous guess was also wrong, after possessing the "thinking visual sense", the four-dimensional world had unveiled the veil of mystery to him, and he was no longer confused before.

He realized that Xu Zhiqiang's transformation was not really a giant, whether he transformed or not, in terms of three-dimensional length, width and height, he had always been his original height.

He became only a spatial warp, the fourth dimension, and when he activated his ability, the space on his body distorted and contracted, making him the fourth dimension, extremely growing, and there was a phenomenon of ascending.

While the space on his body distorted and contracted, the space around him elongated and expanded, thus creating the illusion that his size was rapidly becoming larger.

Of course, because human vision is still three-dimensional vision, only a corner of the four-dimensional can be seen, and a large part of Xu Zhiqiang after transformation is not in the sight of ordinary people, but in the space that cannot be observed.

It's just that this part is not the usual sense of length, width and height, and naturally it can't be described in terms of size, at least in terms of three-dimensionality, the body shape has not changed from beginning to end, and what has changed is only the fourth dimension, the spatial warp.

Luo Yuan walked out of the cave and looked at the sky, suddenly with a shocked expression, at this time, in his eyes, the universe seemed to be countless times wider.

At this time, the sun has not completely set, under the four-dimensional vision, the sun is "bigger" than the three-dimensional time, stars, black holes, this kind of gravitational celestial bodies, not only across the three-dimensional world, but also appear in the four-dimensional, three-dimensional celestial bodies, more like a projection, perhaps the real universe is not three-dimensional, but four-dimensional.

It's just that humans can't perceive it, they can't measure it, and all they can do is make mathematical reasoning.

In this vast space, there are not only star matter, but also endless energy, such as smoke and dust, such as nebula, all kinds of color light and shadow change, stirring and rolling in the space.

Luo Yuan suddenly had a glimmer of realization in his heart, perhaps this is the dark energy that the scientific community has not really recognized so far, and these energies occupy most of the mass of this universe.

In his four-dimensional vision, there are no more secrets in space.

He found that in this state, he could see farther, and his vision could "bypass" the mountains, "bypass" the arc of the earth, and "see" thousands of kilometers away, but this vision was extremely blurry, and he could only see the general terrain.

ps: I've been thinking about this chapter for a long time, and I don't know if this fourth dimension is original, so let's read it if you have different opinions.
