"What kind of place is this?"

Before Xiao Yuan transformed his consciousness into the sine wave, he had imagined what it would be like after the successful transformation: perhaps it was like when he first entered the brain system and he saw that everything was full of points of light, or as he once was, standing in the endless void in total blackness, or even as if he was standing outside the world, like looking at flowers in a mirror......

But Xiao Yuan saw the situation and the above are different, when his consciousness is transformed to the string wave, he neither sees the light point, nor stands in the endless void, the space here is not empty, the ubiquitous fluctuations are filled in it, but these fluctuations Xiao Yuan can only feel, but can't see, what he can see is some other scenes that make him feel strange, these scenes are difficult to describe in words, if you have to describe in words, Xiao Yuan feels that it is more appropriate to use slides to describe, It's just that these slides are true three-dimensional images.

In one of the three-dimensional images, Xiao Yuan saw a familiar image frozen, a huge vortex in the central system, and a vortex on the edge of the edge that had not yet been swallowed by the huge vortex, and he also found a light and shadow in a certain control core center, that light and shadow did not have a specific image, but Xiao Yuan knew that it was himself, the reason why he could feel his body at that time was purely a psychological feeling, in fact, the shapeless light and shadow was what he really looked like in the central system.

"Where's the guy who controls the whirlpool?"

Xiao Yuan searched for a while, and soon found another light and shadow in the center of the whirlpool.

That light and shadow should be the guy who controls the whirlpool, Xiao Yuan speculated.

Just like a cartoon has a series of continuous images playing quickly, Xiao Yuan can see more images than just now, in front of and behind that image, there are more images, if these images are played at a very fast speed, you will get a dynamic picture, and this picture is exactly the scene he has experienced, when he wants to see who cut off his connection with the brain system, but because the situation happened outside his consciousness perception and found nothing.

"This is the image I just experienced." Xiao Yuan easily discovered such a fact, the end of these picture sequences is the moment he leaves the central system, but the beginning extends forward to the unreachable, with no end in sight.

"What happened after I left, why can't I see it?" Xiao Yuan thought of this question and fell into deep thought.

"Strings, the basic constituent elements of space-time, can also be said to be the origin of space-time."

"Not only space, but also time, is made up of strings, and it is inappropriate to treat time and space separately, the universe we live in should be four-dimensional, and above the xyz three-dimension of space, there should also be a fourth dimension - time t."

Xiao Yuan felt that he had grasped the essence of things.

"How should the four-dimensional coordinate system of the universe be established?"

Thinking of this, Xiao Yuan had a little realization in his heart, the cosmic coordinate system is not simply to add a coordinate axis on top of the three-dimensional coordinates of the three-dimensional space, but to treat the entire three-dimensional space as a whole, and the space at a certain moment is an image he sees in front of him, and put all the images on the coordinate axis of time to form the fourth dimensional time coordinate set.

This is like a high-speed train, at a certain moment t0, if the time stops, you can get a state of the train at that moment (x0, y0, z0, t0), where x0, y0, z0 represent the three-dimensional space position of the train, this state can be represented by a three-dimensional image, when the time is carried to the next moment t1, another three-dimensional image (x1, y1, z1, t1), and so on, the three-dimensional images of all moments are connected in series, The result is a coordinate model (x,y,z,t) of a train moving at high speed in time and space, which can be called four-dimensional space-time points.

"I see." Xiao Yuan understood the essence of these continuous three-dimensional images in front of him, but he didn't understand why the time train stopped after he entered the sine wave state, "What caused the time to stop?" ”

"If I go back again, time can go on?" Xiao Yuan thought about this question again, and in order to determine whether this was the case, he even had the urge to try it himself.

"How do I get back?" This is also a problem that Xiao Yuan needs to solve, you must know that he was sucked in, and he doesn't know how to get out.

"If I want to go back, I must establish a fluctuation carrier that can carry my consciousness at the moment of return."

"The carrier of consciousness already exists at these four-dimensional points of time and space, that is, the data flow that carries my consciousness in the central system, and even further considers, the carrier of consciousness before I enter the central system should be my own brain."

Thinking of this, Xiao Yuan suddenly had an idea that made him extremely excited: "If I can choose the time point I want to go back at will, wouldn't it mean that I can travel through time and space!" It's just a time trip to consciousness, but it's the same thing as my previous rebirth, and maybe I'll be able to change a lot of mistakes I made after a certain point in time. ”

"But what can I do to get my consciousness back into the flow of data?" Xiao Yuan had to think about this problem again, if this problem could not be solved, no matter how tempting the previous ideas were, it would be futile, and it was impossible for him to stay in this string wave state all the time, and he would have to return to reality after all.

At this time, Xiao Yuan focused all his attention on how to solve the matter of getting himself back back.

"How did I get in?"

Xiao Yuan's first thought was about this problem, when he deleted the carrier data stream in his central system, so that his consciousness lost his carrier body for a while, and finally came here.

"If I subside the string wave that carries consciousness here, will I be attracted by my consciousness carrier at a certain point in time and space?"

"This kind of attempt is too dangerous, and if it fails, it really can't be recovered."

Thinking of this, Xiao Yuan couldn't help but smile bitterly, and there was nothing he could do, everything he did was to cross the river by feeling the stones, without any previous experience to learn from, once he failed, he would never recover, but knowing this, he had to take risks, although this space looked very mysterious, and even had a feeling of controlling time and space, but he was going back after all, and it was impossible to stay here all the time.

"Maybe I can keep a backup of fluctuations here and leave a way out for myself."

Xiao Yuan finally felt that it was better to be cautious, and decided to leave a fluctuation backup here, how to leave a fluctuation backup here, he thought for a moment and thought of a way.

To drive his consciousness, Xiao Yuan temporarily stayed away from those four-dimensional space-time sequences, and came to an open place, he had to do some experiments first, trying to enhance his consciousness fluctuations, after trying, what he thought would take a lot of effort to do was only completed in the moment of thought, although he didn't understand why his consciousness could easily drive the sine wave, but the goal was achieved, but he was pleasantly surprised.

When a stone falls into the water, it will be a fluctuation on the surface of the water from the inside to the outside, the larger the stone, the greater the amplitude of the fluctuation, and the greater the effective range of the fluctuation propagation, and at this moment, Xiao Yuan's consciousness only exists in a small range, in this space full of fluctuations, it is not an exaggeration to say that it is a point, when his consciousness fluctuations become more and more intense, the surrounding string waves that match his consciousness fluctuations begin to resonate with his consciousness, and the resonance range is getting larger and larger.

"It's a wonderful feeling." A sudden feeling hit his heart, as the resonance range of consciousness fluctuations became larger and larger, Xiao Yuan suddenly felt a burst of spiritual pleasure, this pleasure was extremely strong, Xiao Yuan felt that he had never felt such a strong sense of pleasure in his life, and the pleasure at the moment when Tang Sa Huan reached its peak was less than one-tenth of this moment, so that at a certain moment he was about to get lost in it and couldn't bear to leave.

At that moment of disorientation, Xiao Yuan suddenly woke up, and secretly said in his heart that he was lucky, if it weren't for the more than 100 years of experience he had experienced in the ultimate transformation of the brain system, he might really be lost.

After waking up, Xiao Yuan immediately made a decision, stopped continuing to enhance mental fluctuations, and the pleasure slowly disappeared, Xiao Yuan breathed a sigh of relief, jumped out of the resonance center with his driving consciousness, stood outside the resonance area, observed for a while, and found that the fluctuations caused by the resonance in the area did not disappear, and even did not weaken because of the departure of the resonance source.

"This area can be used as a vehicle for my consciousness." Xiao Yuan made such a judgment, because the fluctuations in the resonance area were caused by the resonance of his consciousness fluctuations, which were completely consistent with his consciousness fluctuations in frequency.

After making this carrier, Xiao Yuan did not make another carrier, because he was worried that this kind of carrier would be too much, and once he calmed down the existing consciousness carrying fluctuations, the wave source he created just now would definitely have a gravitational pull on his consciousness, and he didn't want to be like in the central system, because too many gravitational sources would affect his departure.

Xiao Yuan came to the four-dimensional space-time sequence again, thinking about whether he wanted to return to that space-time point, and after some thought, he finally made a decision.

After selecting the specific four-dimensional space-time point, he stood in front of that space-time point, and did the opposite of the resonance zone created just now, weakening the strength of the sine wave that carried consciousness, and as the strength of the sine wave gradually weakened, Xiao Yuan felt more and more weak, so that he felt that he might fall asleep at any time.

"You can't sleep, maybe a little weaker will do." Xiao Yuan comforted himself like this, and with his strong self-control, he controlled himself to maintain the last trace of clarity in his heart, until that piece of clarity became weaker and weaker, to the point where he could no longer bear it and was about to fall asleep.

"Am I thinking the wrong way?" At this moment, he had a trace of doubt about himself, but he didn't stop, and decided to make one last attempt, if it didn't work, stop weakening immediately, and find a way after recovery.

"Weaker!" Xiao Yuan roared wildly in his heart, and the string wave finally weakened to a critical point under the control of his consciousness.

Xiao Yuan suddenly felt that he was asleep, but in fact he was not asleep, in this moment of sleep, the feeling of floating after deleting the data stream that carried consciousness in the central system appeared again, and at the same time, he felt countless gravitational forces attract him away, the largest of which came from the point of time and space closest to him, where there was a data stream that could carry his consciousness.

With a soft sound, Xiao Yuan felt that he had broken through a membrane again, and his body fell rapidly, and soon it was combined with that data stream, and the sense of presence of his body appeared again.

After the return of consciousness, Xiao Yuan decisively cut off the connection with the central system, and the consciousness returned to the brain system and took off the brainwave helmet.

Whew, Xiao Yuan let out a long breath, stood up from the seat, shook his still somewhat drowsy head, moved his limbs, and suddenly had a feeling that some wanderers had returned to their hometown, his nose was sore, and he wanted to cry, but he knew that now was not the time to feel nostalgic, because in the original time and space, he was still in the central system at the moment, and soon his consciousness would be cut off from his brain system.

"Come on, let me see who is cutting me off from my brain system."
