"Five-dimensional space? But I don't think it's any different from the outside, right? Diana said with a shrug.

"This is attributed to the cognition of the human brain, we are four-dimensional creatures, the limitations of intelligence and brain structure make us unable to perceive space above five dimensions, and even we should say that we belong to three-dimensional creatures, we can't see time, for time, we only exist in the abstract, the difference is that we believe in time, so we have the opportunity to become close to the level of four-dimensional creatures."

Kexin patiently explained:

"For example, an ant is a two-dimensional creature, in its life, there is only a plane, although it lives in the space of four dimensions, but it cannot see the space above the second dimension, so even if it lives in a higher dimension.

For example, the ants we see on the island, even in the five-dimensional space folded into this four-dimensional space, in its eyes, it is also two-dimensional, there is no difference, we are the same, we can only see the three-dimensional, feel the fourth dimension of time, higher, our brain can not reach that level. It is said that dolphins can, but it is not known. ”

"According to you, the universe has so many dimensions, why do you believe that the earth is in the fourth dimension, not the higher dimension?" Yun Yanuan asked.

"It's very simple, no matter how high the dimension, the most basic composition is three-dimensional space plus time, the four dimensions are the most basic mode of the universe, countless four-dimensional universe makes up this multi-dimensional universe, but if this island is artificial, then it must be five-dimensional, because the folding in the space, here must only be five-dimensional, can not be lower.

This also reminds me of an interesting thing, about the Classic of Mountains and Seas, perhaps one can explain some of the mysteries in the Classic of Mountains and Seas. Kexin seemed very happy, and for those who were eager to learn, she was enjoying all this.

"The Book of Mountains and Seas originates from the Mountains and Seas, and the last time the Mountains and Seas Charts appeared in their entirety, was on the Qin King Jiuding, I was fortunate to see a part of the rubbing, which was unearthed in the emperor's tomb, which should be true, and we found a problem, that is, the Mountains and Seas Chart is not a map of China's mountain ranges, but a map of the mountains of the entire earth, which can already be verified.

But the difference is that the mountains and seas are larger than the world map, much larger, some of the land has disappeared inexplicably, gone, we can't find it, as if there is a piece missing in the middle of the mountain and sea map, and now I can explain all this, if this space is artificially folded, then the land that disappears in the mountains and seas map is in these folded spaces, on this earth, there is more than one folded space, as far as I have seen the mountains and seas map, you can conclude that there are at least three such folding spaces.

The Earth is much bigger than we think. Oh my God, if one day, these folded spaces are fully opened, what a magnificent wave the earth will be. "But I looked at the bonfire, but I felt that her eyes were hotter than the bonfire.

"Don't, when you folded these spaces, you don't know how turbulent the earth is, you open the space now, boom, the earth has become bigger, okay, the big earthquakes and floods are light, it's hard to go directly in half!" Yun Yanuan scolded with a smile.

"Isn't it worth it for a short-term disaster in exchange for a vast fertile land, a real world?" Kexin retorted.

Yun Yanuan shook his head and said:

"I just know that I won't live to be more than 100 years old at most, and the things I think about are limited to these 100 years, and I can't think about things that are farther away, and I don't want to think about them. I only hope that this life will be happy, there will be no danger, be happy, eat, drink and have fun, it is best to find a rich woman to marry, and it is best to eat and wait for death to have all kinds of fun. ”

Diana hurriedly pointed her finger at herself, and said a few words: "Here, here, here!" Haha"

The four of them burst into laughter.

The thunderstorm continued, and they were lucky to find these fallen trees as beams, which were much stronger than those of the pillars, and with today's wind, the sloping houses would undoubtedly disperse. The fallen tree was right in the leeward direction, keeping four people warm and sheltering from the hurricane blowing towards the campfire.

Today, there is no way to catch small fish to eat, so I have to gnaw on the old, the dried sea fish has eaten enough, everyone decided to be unhealthy once, eat some roast wolf meat, sprinkle salt on the wolf meat that has been buttered, make a sizzling sound, and after a while, the aroma of meat spreads, attracting several people's index fingers.

It is very dangerous to barbecue like this in the wild, it may attract large animals to prey, but today there is no need to worry much, in such weather, any creature must obediently hide in the nest, the power of thunder and lightning, in the powerful beast, also have to hibernat. So, they can now rest assured that they can barbecue and eat large pieces.

There is still a big difference between wolf meat and dog meat, wolf meat is more fishy, and the meat fiber is coarse, and the taste is far inferior to dog meat, but after grilling, it is still okay. After eating several meals of fish and meat, Lingding changed the taste, and the taste buds felt more vivid and exciting, and several people were happy to eat.

The four people brought a lot of salt, and on the seaside, especially on the seashore with more rocks, air-dried sea salt crystals were everywhere, and there were even large crystals, which looked like white jade.

These salts are placed in the warm grass basket of Yunya, this thing is very heavy, but it is something that cannot be left uncarried, in the wild, if the salt in the body is insufficient, it will lead to dehydration and weakness, and even grow a lot of gray hair. If the salt is used properly, it is enough for four people to use it for a month or two, especially since the mouths of several people are not very heavy, and they can't eat too much salt at each meal.

So Yunya Nuan is very afraid of rain, that is, he is afraid that these salts will be wet by heavy rain, which is bad, although there is salt in the body of wild animals, but the sodium content is not enough. Fortunately, the snakeskin was about to be cooked, and he was going to make a pocket out of the snakeskin to place salt, so that even if it rained, a few people would not have to worry about losing this important material.

After the seaweed is dried, it also takes up a lot of space, and several people are helpless, all kneaded into pieces and a ball, to help them supplement the trace elements of iodine and calcium, and at the same time can also supplement salt, and the weight is light, Yunya Nuan really regrets not getting more seafood, although it is not delicious, but it is easy to use.

The rain was pouring down, and there was no intention of stopping, this arched slope house was very strong, so that four people could sleep peacefully, there was no need for vigil at all, three and a half sides were beams and columns, very dense, there was only one exit, but there was a bonfire, such a guard was enough.

But they still encountered a problem, that is, in the middle of the night, the cloud cliff warmed up to add firewood, but found that there were no dry branches, which was also a helpless thing, after all, the thunderstorm did not leave much time for a few people at that time, and the firewood that could be collected was very limited, which seemed to be enough at the time, but obviously the estimation was wrong, remember that Bell once said, you have to prepare three times the amount of firewood you think is enough, then you are safe, they obviously made such a mistake.

The weather was very cold and humid, and if there was no campfire, it would be enough for a few people. But in such a heavy rain, you may not even be able to open your eyes, where can you go to find firewood? There is no way, they can only face the reality, the four of them are ready to use their body temperature to carry through the dark night, and after dawn tomorrow, if the heavy rain does not stop, then they can only brave the rain to find firewood.

In order to be able to make a fire smoothly tomorrow, Yun Yanuan had to ruthlessly withdraw the burning stick, bury it with soil, so that it could not continue to burn, and then take it out and put it in a shelter for tomorrow's fire, because if the heavy rain does not stop, there will be no dry firewood available, and these carbons are their only hope for re-making the fire.

In the coldest second half of the night, they lost their bonfire, four people huddled together, using each other's body temperature to keep warm, such a clammy cold is fatal, colds and colds can occur at any time, and the environment makes several people have to give up what men and women do not kiss, and gather together with each other.

Take off the wolf skin vest on your body, unfold it, and superimpose it on your body, unable to lie down and sleep, because it is too cold, the four of them sit together, lean their backs against each other, and cover the front with the unfolded wolf skin vest, try their best to keep their body temperature, and wait for the dawn to come.
