The laws of time and space are undoubtedly the most secretive, the most difficult to touch the essence, and the most difficult to understand among the laws known to mankind.

Even if a person with the ability of time and space talent can use some time and space power, he may not be able to deeply understand the laws of time and space.

Because time does not exist in nature, human time is only a ruler that belongs to human beings, a yardstick used to express the change of things - from day to night, from birth to death, from freshness to decay...

And this ruler is only for human beings themselves, if it is placed in the macrocosm of the universe, it can never be used as an accurate measuring scale, and because it has no substance, it cannot be called 'existence', so it is very difficult to define it.

If you can't define it, it's hard to understand, it's hard to understand, and how can you touch the essence? And without essence, it limits the use of it, including the capable.

As for space? Perhaps compared to the abstraction of time, its existence is more real, from point to line, from line to surface, to three-dimensional...

But that's the limit!

Just as the two-dimensional world cannot imagine the three-dimensional world, the human beings of the three-dimensional world use length, width and height to define the basic three-dimensional space, but they cannot imagine the four-dimensional, let alone define the fourth dimension In addition to the length, width and height, what should be another point that accurately describes it?

Does even four-dimensional space really exist? Humans can't be sure that the only argument comes from mathematics alone.

After all, mathematics is the foundation of all basic sciences and can be understood as a way of describing it closest to the objective essence.

After all, the cold numbers do not accept any distractions, nor do they have any emotions, and only pursue truth and accuracy.

"If only I were a math genius." Tang Ling muttered and fixed a huge fierce beast bone to the shelf of the hut that had been erected.

With the fixation of this beast bone, the hut had begun to take shape, and it looked quite presentable, with two rooms upstairs and a hall downstairs, as well as a kitchen and bathroom.

In front of the door of the small building, there is also a special courtyard, in which there is a pond, and in the pond floats an object the size of a coconut.

If you look closely, the object looks like an egg, but the color of the eggshell is very strange, at first glance it looks like black, and when you look closely, it looks like the background color of the night sky, that kind of dark blue with a velvety feeling.

In addition, there are faint purple lines on this egg, which look like the arcane talent law patterns on the bones of super-level fierce beasts, and they also look like super-technological patterns, and there is an inexplicable feeling of agility.

Such a peculiarity, of course, does not make people sure that it is an egg.

But Tang Ling knew that this was definitely a genuine egg, which was condensed by the owner of the desert island and the daylight ghost fish after being reborn.... Life forms?

Tang Ling can only describe it like that, after all, rebirth is too mysterious, whether this egg will hatch, or will it always exist in the form of an egg, who can be sure?

As a 'breeder', only Tang Ling knew that this egg had begun to have thoughts and perceptions, and could express his emotions in the simplest way.

Just like now, it was fished out of the lake by Tang Ling, soaked in this pond with a certain gift from the sea god, it was very happy, rolling back and forth in this small pond, refusing to sink, and kept floating on the water, wherever Tang Ling went, it floated to wherever it went...

Such a magical egg?

That's why Tang Ling had the strange idea that it would exist in the form of an egg!

"Muttering about what?" On the other side, he was squatting on the side of the pond, cooking with simple tools, and when he heard Tang Ling muttering in a low voice, he felt very sensitive.

In fact, Tang Ling was very busy on this day, cutting trees and burning grass, leveling the land, digging ponds, fetching water back and forth, filling ponds, carrying all kinds of sundries, and then building houses...

If it weren't for the fact that he was a quasi-Purple Moon warrior, compared to the ordinary people of the previous civilization, he was simply a superman, and he would never be able to complete these trivial tasks in one day.

In fact, if it was just Tang Ling alone, he wouldn't need to be so particular, but no matter where he was, he must do his best to make the other side live a relatively comfortable life, and this idea made Tang Ling willing to waste a day or two to do this.

The meaning of time for Tang Ling is to use it for worthwhile things.

But such busyness is also destined to be the 'heavy responsibility' of cooking falls on the other side, and the craftsmanship of the other side has never been indescribable.

Maybe knowing this, the other side will be sensitive, afraid that Tang Ling is muttering about the matter of waiting for the meal.

There's no way, even if it's unpalatable, I want to cook for him... Such an idea is very firm, so now I can only grieve and let Tang Ling help hone his skills.

Can't stop eating!

Is this a girl's little willfulness? The other side couldn't help laughing, humming happily, completely forgetting the little fierceness when he was still asking Tang Ling a second ago.

"Uh, I'm just..." Tang Ling grabbed the back of his head, trying to explain to the other side that he was muttering about mathematics, but how to organize the language from beginning to end with such a complex idea?

But I didn't expect that I had only said a few words, and the other side had already begun to hum happily, and sure enough, just like what was said in the former civilization book, the girl's emotions couldn't keep up?

"What's the matter, so happy?" Tang Ling wiped the sweat from his forehead and squatted beside him with a little flattery.

The other side habitually touched Tang Ling's hair, and after they made up their minds with each other, Tang Ling looked like a dog many times.

Unable to hold back such thoughts, the other side smiled even sweeter, and replied to Tang Ling casually: "It's nothing, thinking that our house is going to be built." ”

"Are you so happy?" Tang Ling sniffed, judging from the smell of the food, he had an ominous premonition, but this could not be shown, Tang Ling looked calm and changed the topic: "But it's really amazing, it should be the most luxurious house, right?" The super-level beast bone is used as the structure, and then I will use the beast skin to cap and make the wall. ”

Speaking of this, Tang Ling couldn't help but be a little excited: "Even if you are a high-level Purple Moon Warrior, you can't get such a house, right?" ”

"Uh-huh." The other side obviously didn't have much interest in these, just nodded, anyway, Tang Ling thought it was good, so let's do it.

In fact, this was also Tang Ling's flash of inspiration, whether it was a fierce beast bone or a fierce beast skin, it was a gift left to Tang Ling by the owner of the desert island.

After all, it is impossible for the beast skin to be used as food and directly used to replenish energy, as for the beast bones, there are two types, one is edible, but almost three-quarters of these must be reserved for the nutritional supplement of the desert island owner after rebirth.

The other, which is full of law patterns, is inedible, and its use is the same as that of beast skin, and it is best used as a material to create practical equipment.

The materials about this super-rank fierce beast were extremely precious in the Purple Moon Era, and their benefits to the Desert Island Island Master had already been explained in detail in the last information left to Tang Ling.

Aside from all of them, one of the things that Tang Ling cared about the most was that this material would not lose its activity, it would automatically absorb energy and maintain their 'strength', and from this alone, he knew the preciousness of the super-level beast material.

But it's not precious, it doesn't have much meaning in this space-time fragment, and Tang Ling doesn't have the ability to create them, or use them.

It's just that when building the house, Tang Ling suddenly thought of a possibility, at the stage of the super-level fierce beast, the skin and bones already have the ability to absorb energy all the time, but to maintain their own 'strength', it is not enough energy.

The excess energy should be absorbed by the body.

But now that there is no body, the excess energy should overflow... So, using them to build a house is also a kind of use?

Thinking about staying in a room full of energy every minute and every second, it is also beneficial to accumulate over time, after all, in this fragment of time and space, there is no purple moon, and it is not like the outside world can sense sufficient energy after entering the cultivation.

Anyway, even if it doesn't work, there is no loss, after all, the house made of super-grade beast materials is strong enough.

Of course, Tang Ling was not worried that these materials would not be able to absorb energy.

The owner of the desert island specifically mentioned that as long as there is a law of operation, there must be energy, and the so-called law operation contains too vast - the rotation of the planet, revolution, tides, water, fire... Wait a minute.

It's just that Tang Ling can't feel these energies at the quasi-Purple Moon Warrior stage, but the super-level fierce beast can absorb these energies, and the fierce beast skin it leaves behind is just as good as the fierce beast bones, and the rest is just to verify whether his idea is feasible?

Tang Ling was a little absorbed in her thoughts, and the other side didn't bother, she just looked at Tang Ling quietly with her cheeks back, she liked to see Tang Ling thinking, and she always felt very charming, so that the stew she was cooking was a little mushy.

"What does it smell like?" The other side was fascinated, but Tang Ling discovered this problem first.

The other side was startled, stuck out his tongue in embarrassment, and was a little scrambling to take the pot down.

"Come on, don't get hot." Tang Ling stopped the other side and began to clean up very quickly.

The other side quietly watched Tang Ling busy, I don't know why, the smile on his face gradually became a little sad, but Tang Ling was busy intently, and he didn't notice the change in the other side's expression.

Very casually, the other side asked: "Is it starting to break through tomorrow?" ”

"Hmm, I don't know if I'll be able to finish it tomorrow?" Tang Ling never cared too much.

"If you can..." After hesitating for a while, the other side suddenly spoke very seriously, and Tang Ling looked up in slight surprise and looked at the other side.

The other side exhaled and said, "I mean, if you can, you must break through tomorrow, and don't change it." ”

"Why do you care so much about that?" Tang Ling put down the pot in his hand and sat beside him.

The other side took out a handkerchief, and while helping Tang Ling wipe his sweat, he said, "You tell me, the speculation left by the owner of the desert island is that the flow of time here is slower than that of the outside world. ”

"I don't know how much slower it is compared to the time in the outside world. But we have to go out anyway. ”

This sentence from the other side doesn't seem to have any logical relevance, and others will not even understand it, but Tang Ling understands the meaning of the other side's words very well.

They had been in this fragment of time and space for more than half a year, which meant that compared to the delay of the outside world, the other side was no longer willing to waste even a minute of Tang Ling's time.

Because combined with the speculation of the owner of the desert island, Tang Ling also had his own guess, although the time flow rate of this piece of space-time fragment was abnormal, but combined with various clues, this mountain should be a 'different place', and it was very likely that the normal time flow rate was retained.

If you stay on this mountain in the future, there is a great possibility that there will be no time difference with the outside world.

Therefore, after deciding to leave this fragment of time and space, Tang Ling would take the other side to this mountain to live, so as not to distance himself from the world too much after going out...

After all, no matter what your strength is, grievances and grievances will never disappear!

"You're worried?" Tang Ling understood the words of the other side and asked like this. In fact, Tang Ling was a little surprised, because the other side had always cared not much about this, and after entering this fragment of time and space, there seemed to be some changes.

"Hmm." The other side nodded directly, but did not explain too much.

"Tomorrow, you break through first." Tang Ling thought silently for a while, and then replied like this.

"What about you?" The other side was very surprised, according to what Tang Ling said before, he should have been ready.

"I need to validate one of my ideas." At this time, it is already evening, the soft sunset is sprinkled, and looking down from the mountain, the whole town seems to be plated with a layer of golden soft light, which is very beautiful.

And the sky on this mountain is still a strange gray-blue, like the sky at the junction of day and night...

Tang Ling was not surprised by this, because he was used to seeing it.

The sunrise and sunset outside will naturally affect the change of light and darkness here, but Tang Ling, who has the instinct of precision, has already seen it clearly, the sky here has not changed at all, it will always be the same gray-blue, of course, it will reveal its original appearance at the moment of dusk.

While looking at the sunset under the mountain, Tang Ling held the hand of the other side.

"What ideas do you want to test?" The other side naturally leaned on Tang Ling, and the jumping firelight made the other side's face flush, looking beautiful and a little shy.

"Here." Tang Ling pointed to his dantian, and then said, "The energy I have accumulated is already very thick, and I always feel that they are condensing..."

Speaking of this, Tang Ling lit a cigarette: "I don't know if my hunch is right, but I always feel that when they are completely condensed, it is the limit of energy I can accumulate, and I want to try to break through when I accumulate to the limit." ”

"Have you heard anything from the outside world? What about the accumulation limit? I don't know why, as soon as I leaned on Tang Ling, the other side would be unconsciously lazy, and even her voice was a little soft and gentle.

"No, what the outside world says is nothing more than to achieve the power of nine bulls and two tigers, and then try to store more energy in the dantian before the breakthrough, and then obtain three resources to help break through, which is a perfect breakthrough." Tang Ling took a cigarette in his mouth, looked into the distance, and said very casually.

Of course, I know about these on the other side.

"It's just your guess, so do what you think." After saying this, the other side and Tang Ling actually said at the same time: "After all..."

Then the two men looked at each other and smiled again.

"Say it." The other side closed his eyes half-closed and grabbed Tang Ling's arm.

"After all, there is no way to make up for the time that has fallen, so we can only use a more radical way to see if we can catch up." Tang Ling thought so.

"That's what I think, and I think you're going to be right." The other side is really the same idea as Tang Ling.

"Then you... Do you want to try to accumulate to this stage and then break through? Our resources are sufficient. Tang Ling flicked the fire in front of him.

"No, I'm different. And—" The other side seemed to be about to fall asleep, and his voice became softer: "Moreover, I can't do this kind of accumulation, the energy doesn't have a tendency to condense like yours, and I think others can't do it like me." ”

"Am I so special?" Tang Ling scratched his head, in such a place where there was no quarrel with the world, where there were only two people, it seemed that something unusual had happened, it was not worth investigating, and it didn't matter what a fuss about.

The other side opened his eyes and looked up at Tang Ling, very seriously: "Of course, you are the most powerful!" ”

Tang Ling couldn't help but smirk, rubbed the hair on the other side, and then took out a roll of bamboo slips from his space.

Undoubtedly, this bamboo slip was the most precious thing Tang Ling had exchanged for from the Dream Domain, "Forging Eyes", he had already shared it with the other side, but unfortunately, it seemed that only Tang Ling and Tang Long could cultivate in this world.

This is for the precision instinct, and the only people in the world who know to have it are the two brothers.

"And this... That's why I'm not in a hurry to break through. Tang Ling spread out the bamboo slips in front of the other side, not afraid that the fire in front of him would burn the bamboo slips.

This thing seems to be invulnerable, which Tang Ling discovered by chance.

The other side seemed to be uninterested in anything again, and just glanced lazily, waiting for Tang Ling to continue.

"See this, it's about my precision instinct, no, now I should change my name to the first stage of the spiritual eye." Tang Ling pointed to the words and patterns on the bamboo slips, and explained to the other side with some excitement.

"In fact, the cultivation stage of the spiritual eye is best combined with one's own strength in order to achieve perfection. Just like now that I am a quasi-Purple Moon Warrior, strength is the first stage, and before I break through the second stage, it is best to break through the spirit eye to the first stage. ”

Tang Ling's words undoubtedly aroused the curiosity of the other side, and she raised her eyes and asked, "Could it be that after so long, your spiritual eye has not broken through the first stage?" ”

"Well, how do you say that? In terms of ability, it has broken through the first stage, and is even close to the second stage. But not a complete breakthrough ... After all, who could know that there was a cultivation method for precision instinct? Boss Huang taught me some, but it was not complete. I want to cultivate it completely. Tang Ling explained to the other side.

"Well, that's right."

"Also, it's a small species." Tang Ling muttered: "I feel that it has finally recovered, but it is not completely recovered, I have to wait for it to wake up." ”

In front of the other side, all Tang Ling's secrets were spread out, including the small species.

And there is no doubt that Tang Ling is waiting for the best opportunity to break through, even if he already knows that it is very likely that he has fallen far behind the outside world, Tang Ling is still not impatient.

It's just tomorrow, will the breakthrough on the other side go smoothly? Tang Ling was a little worried, but thinking of the mysterious strength on the other side, he inexplicably had some confidence.

But why is the other side so powerful? The other side never told Tang Ling, but Tang Ling had some guesses.
