"In the darkness of the unknown, it merges with the despicability of copying wisdom, and then blooms the flowers of calamity, and destroys all beings."

……

The closer he got to the center, the less light Zhang Yu could see.

He thought to himself, if he stopped at this time, would the darkness also stop? Or does he choose to retreat at this point, and the Light will retake it?

Many ideas overlap over and over again.

Zhang Yu's footsteps did not stop, he saw a door, looking from afar, as if it was still far, far away from him.

The sense of distance is very strange, as if the door is constantly moving, and there is always a relative, unbridgeable distance between Zhang Yu and the door.

The light dimmed a little more, and the palm prints were moving, increasing.

Although Zhang Yu has experienced a hundred battles, he is no longer the cowardly and incompetent person he was on the train, but he is still inevitably afraid in the face of unknown enemies.

This is the most instinctive, the desire to live.

Seeing that he couldn't get close to the door, Zhang Yu forced himself to stop.

He shifted his attention from the door to the surroundings.

Move into the darkness and expect a chapel in the darkness, a demon that herds the darkness and erodes the light.

But in the darkness he could see nothing.

There was the sound of the wind whistling in my ears, and the wind was faintly mixed with some inexplicable whispers...... At first, Zhang Yu thought that he was having auditory hallucinations, but when he collected these sounds and analyzed them one by one, he found that they were not auditory hallucinations, but real sounds.

"In the darkness of the unknown, it merges with the despicability of copying wisdom, and then blooms the flowers of calamity, and destroys all beings."

When the final result was revealed, Zhang Yu knew that Zhang Yi had deceived him again.

He'd been here, he must have tried to get through this area, but he failed...... But he was lucky that he wasn't trapped here, and he escaped...... And then have been waiting for the next ......

Zhang Yu: These people are Zhang Yi's next time.

Thinking of this, Zhang Yu became murderous towards Zhang Yi.

This guy is full of lies, even if he didn't intend to harm Zhang Yu and the others, his existence was just trouble for Zhang Yu.

However, this is all for later, and now Zhang Yu has to find a way to cross here, or leave here.

After waiting in place for a while, Zhang Yu decided to move on, but the pace slowed down a lot, and he wanted to shift his attention from the door to every detail of his own progress.

From the outside, this central area is not large, and with Zhang Yu's speed, he can walk through the entire area in only half a minute.

Now, however, he had advanced here for at least ten minutes.

Ten minutes...... The data showed that he had traveled a total of 1,900 meters, which was well beyond the central area of the outer observations.

In other words, the central region is just a general concept, and it must be wrapped in a diffractive spherical space.

Zhang Yu didn't know much about spherical space, but he had heard about "diffractive spherical space" when he was with Li Bo'an before.

——

Usually, we think that space is square, but in fact, the specific feeling of space is the inertial cognition that our human life world brings to us ordinary people

"surface" makes our perception of space tend to be regular and three-dimensional.

But in reality, the exact shape of space is unknown.

At least in the absence of a specific building to determine the scope of space, space should be infinite for us.

But this state of infinity is too broad, so we are still accustomed to describing it in terms of concrete forms when we perceive and feel space.

The concept of "diffractive spherical space" is one of them.

It was not an individual who first discovered that the idea of "diffractive spherical space" was proposed, but the entire physics team of the Glorious Republic.

They have been studying the spatial structure of the Tomb of Pure Sky Fire based on sampling data since the Central Curtain World.

Then they discovered that the reason why the Tomb of Pure Heaven Fire could be all-encompassing in a confined space was because it was composed of countless diffractive spherical spaces that intersected with each other.

Every diffractive spherical space can be thought of as a microscopic microcosm of the universe.

The spatial sequence of the Tomb of Pure Sky Fire was originally arranged in a regular manner according to time, but in the event of the central curtain, all the spherical spaces that make up the Tomb of Pure Sky Fire were disrupted, and they also produced "mirror space" in the collision, which is the concrete space form formed by the diffraction state of two or more "diffractive spherical spaces" in the collision process.

This figurative form can be directly observed by the human eye, and there are also cases where people walk in the tomb of pure heaven and fire and see many wonders.

Of course, that's a far cry here.

Returning to the "diffractive spherical space", some researchers believe that the "diffractive spherical space" is a very unstable spatial structure, and its diffraction makes it difficult to interfere with the structure of the base universe, and will only be continuously digested by the structure of the base universe.

However, in the process of diffraction annihilation of the diffraction of its own structure, the "diffractive spherical space" will continue to produce a "void arc" similar to the interference wave, which is quite similar to the characteristics of the "gravitational wave" (1), but its radiant energy margin is very narrow, so it is difficult for people who are usually outside the "diffractive spherical space" to feel this diffractive annihilation, so there is no need to use the naked eye to observe.

However, if you do break into the core area of "diffractive spherical space", the intruder's perception of space will be confused...... The most obvious is that the spatial extent of the original base universe is either "compressed to the limit" or "greatly enlarged", in short, it is difficult for people in the "diffractive spherical space" to adapt to the spatial state here before merging with this space.

According to the diffraction characteristics of space, two objects in the same diffraction space will be in a relative spacing state, which is the problem that Zhang Yu is facing now......

——

"Is there any way to break this distance?" Jin Yuan asked.

"Of course there are, and there are more than one." Li Bo paused for a moment and said: "One of the most comfortable ways is to wait, as long as your body is completely embedded in the target space structure, you will naturally not be trapped again, but one of the biggest drawbacks of this method is ...... You don't know how long you'll have to wait...... It could be just a few seconds, or it could be a few days...... Or even a few years ......"

"I'll go! Years...... You can't starve to death......"

"So, the bigwigs came up with something else." Li Boan said as he turned on his ATT protective force field, and let the force field completely cover his side in a rectangular state.

"Diffraction waves, when encountering something that can't pass through, it will bend and turn back, the exoskeleton on our body is equipped with an ATT high-energy protective force field, this thing can not only block the impact of energy, but also make the diffraction wave hit the wall, in short, as long as the distance is not far, just open the ATT force field like me and move towards the target!"

"It's that simple?" This was asked by Zhang Yu.

"Yes, it's that simple, but ......" Li Boan smiled evilly again: "But I also said it, provided that the distance is not far away, and your ATT force field can hold up until you make contact with the target." ”

"What if you can't hold on?" Jin Yuan asked.

"I can't hold on to it...... That's a wasted effort, as long as your ATT force field is touched, the distance you traveled before is zeroed, how far you felt from the other person before, and how far away you are now. ”

"Uh...... Is there any other way? Zhang Yu asked.

"Yes, but it's a dangerous option that requires a little courage."

"Tsk, don't sell off, boss!" Jin Yuan was a little impatient.

Li Boan snorted, and then took off a "singularity grenade" from his waist.

"Do you know what a 'wormhole' is?" Li Boan put the singularity grenade at his feet, and then called up a projection of a piece of paper in front of him.

Several people shook their heads.

"Then you should know about the space folding, right?"

This time, someone nodded, it was Jin Yuan.

"I know, I've seen movies, and this kind of thing is too common in objective movies."

"Well, that's easy to do, in fact, the so-called 'wormhole' and 'spatial folding' are the same concept." As he spoke, Li Boan marked the two points of AB on the paper, and then asked, "If I plan to go from A to B now, how should I go?" ”

This was asked to Zhang Yu because he sat the closest.

Zhang Yu was stunned for a moment, and then raised his hand to connect AB into a line.

"That's right, between two points, is the straight line the shortest, something that elementary school students know." Li Boan smiled, and then marked a distance on the line and said: "But if I tell you that the distance between A and B is tens of light years, will this 'short' suddenly become sour." ”

Everyone was stunned when they heard this, and now they can only nod.

"If we still have to go through this journey at this time, even the warp engine of the Sovereign could take centuries...... Therefore, at this time, we need a 'wormhole' to help us ignore the spatial distance between AB, which we call 'folding'! ”

Saying that, Li Boan folded the paper in half, so that the AB points coincided, and then said: "Now the AB points coincide, but in order to get from A to B, we still need to break through the spatial structure here and make a wormhole!" So ......"

Li Boan picked up the singularity grenade, and the meaning was self-evident.

"I've taught you the method, mainly just in case, and by the way, I remind you that if you really use it, you must seize the opportunity...... I don't want to see any of you clumsy and blown up by your own grenades with missing arms and legs! ”

[Gravitational waves: In physics, gravitational waves refer to ripples in the bending of space-time, which propagate outward from the radiation source in the form of waves, which transmit energy in the form of gravitational radiation. Gravitational waves may be the most amazing and incredible form of energy transmission in the universe, and some scientists believe that it can penetrate the barriers of time and space to achieve real cross-time and space communication, and it is also the basis for interstellar communication transmission in the future. 】
