Humans’ cognition of the universe is divided into three levels, namely the observed universe, the observable universe and the real universe.

The so-called observed universe, as the name implies, is the universe that has been observed by humans with existing scientific and technological means.

Due to the limitations of scientific and technological levels and observation methods, the size of the observed universe is not small, but not large either, and a large part of it has been observed, but no specific useful information can be distinguished.

As for the observable universe, it is the full picture of the universe that humans can observe in theory.

Even if the level of science and technology has reached the current standard, the best solution for humans to observe the universe is still through light radiation, which also means that the size of the observable universe of humans is actually limited.

The way to define this size is to use a spherical space with the observer as the center, that is, the light emitted by the object must have enough time to reach the earth.

The most accurate estimate of the age of the universe at this stage is 13.798±0.37 billion years, but according to Hubble's law, since the universe is always in superluminal expansion, the radius of the observable universe is not a fixed 13.8 billion light years. The current distance of the ancient celestial bodies observed by humans is much farther than their original position.

The radius of the observable universe is estimated to be about 46.5 billion light years, and the diameter is about 93 billion light years.

As for the farther places, because the distance is so far that the light emitted since the Big Bang has not had enough time to reach the earth, this part of the universe is outside the observable universe.

What people call "universe" in the conventional sense refers to the observable universe.

In such a large range, there are about 10 to the 24th power to 10 to the 25th power of the number of planets.

Considering that most of the galaxies are occupied by stars, and many planets are planets, satellites, and even comets like Halley, the number of stars that can truly represent the mass of the universe is about 10 to the 23rd power.

This is a rather exaggerated number. Even if only the stars are counted, if they are counted by manpower, I am afraid that they will not be able to count many in a lifetime.

For Zheng Shu, who keeps doubling his strength, how many times does it take to reach this level?

The answer is the 74th round of strengthening.

That is, 2 to the 73rd power, Zheng Shu's volume has reached 97% of the entire observable universe.

When the 75th round of strengthening was carried out, Zheng Shu's volume reached 188% of the entire observable universe, which is almost doubled.

But for Zheng Shu, the influence factors consumed by the strengthening so far are only 7501 points, which is insignificant compared to his current total influence factors of more than one million points.

After taking a look at the situation around his body, Zheng Shu had to use his authority to hide most of his body in the small world.

Otherwise, just "standing" here, Zheng Shu would be enough to cause a disaster that would destroy the galaxy.

Looking for a more spacious "vacuum" area in the universe, Zheng Shu used the space bubble to "push" himself to fly quickly while continuing to strengthen.

As for using space jump directly... With his current volume, if he tears the space, the aftermath caused by gravitational waves and space vibrations alone will be enough to destroy most superclusters.

After surpassing this level of the observable universe, the next level Zheng Shu needs to face is the "real universe".

According to Hubble's law, the universe has been expanding at superluminal speed since the Big Bang, and the speed of expansion is getting faster and faster, so the observable universe is the limit of human beings at this stage.

Compared with the real universe, the observable universe is pitifully small.

According to the conclusions drawn from existing theories and mathematical models, the "size" difference between the observable universe and the real universe is roughly similar to the size difference between an atom and the entire observable universe.

The size multiplier difference between the two sides has even exceeded the limit that humans can describe with digital units!

What's more exaggerated is that the multiplier of this size difference is still getting bigger and bigger with the superluminal expansion of the universe.

So for most civilizations, it is completely possible to think that the universe is infinite.

This is also the important reason why Zheng Shu has always sneered at the so-called single universe level in some science fiction works he has read after understanding the size of the real universe.

If it really reaches that level, let alone individual organisms, even superclusters are not as important as a cell in front of the other party... If such existence still has a structure like "cell".

Even a single universe level like Quantum can only exist because of its special form, and most of the power of the Quantum family is used to maintain the balance of the universe, so it cannot be used normally.

But just a little bit of "residual" power is enough for their entire family to run rampant in that universe.

But now, with the exponential growth and strengthening, Zheng Shu finally has the confidence to reach the real single universe level.

Of course, the most important thing is...

"Too exaggerated..."

Zheng Shu felt the breath around his body and even couldn't understand it.

Looking at the decreasing influence factor on his panel, Zheng Shu confirmed that his strength was indeed increasing rapidly, but the special breath around him still gave him the feeling that there was no change.

Not a single change!

Zheng Shu originally thought that his strength had improved so much that he could at least see the gap with the opponent. Even if he had changed from a frog in a well looking at the moon to an ant seeing the sky, it at least meant that he could get a little closer to the opponent.

But now, that breath was still like a false phantom, and it had no substantial effect except for the tingling horror.

The speed of the decline of the impact factor on the panel became faster and faster, and the speed of Zheng Shu's breath expansion became more and more exaggerated.

With the support of more than one million points of impact factor, Zheng Shu's size was rapidly approaching this universe.

But similarly, in this process, Zheng Shu could also feel an increasingly obvious sense of repulsion, which meant that his size was approaching the critical value of the universe's carrying capacity.

When the number of impact factors dropped below 10,000, Zheng Shu finally had a special feeling.

"Is this... the power of the universe?"

Looking down at his palm, Zheng Shu did not feel that he could not control it. After all, being able to perfectly control power was also part of the "safety protocol".

"Then... the second stage."

Zheng Shu found the quantum reinforcement template on the panel and consumed a little impact factor.

Wave...

As if he had come out of a huge soap bubble, after the quantum reinforcement template was strengthened, Zheng Shu found that his body had been "spitted" out by the universe and came to the outside of the universe's "membrane".

"...Outside the universe, unexpected prosperity."

Zheng Shu looked around and was not surprised at all that he was rejected by the universe.

The quantum reinforcement template itself represents a certain rule of the universe, plus its size comparable to the real universe, combined with the two, in a sense, he has now become a real universe!

Zheng Shu thought that there should be endless void outside the universe, but the fact is just the opposite. Although there is indeed no matter here, there is the minimum energy that can maintain space.

Of course, this level of vacuum is absolutely barren for the universe, but it is too "prosperous" compared to the "void" that Zheng Shu envisioned at the beginning.

"That's right... The alien world and the human world can only get close by relying on the connection between spaces, and there should indeed be space outside the universe."

Zheng Shu looked at the "bubbles" around him one after another, each of which represented the real universe.

Although his vision was no longer effective in such a place, Zheng Shu's other observation abilities still replaced vision to help him collect information around him.

Looking "out", there were endless cosmic bubbles in the void.

"Is it really infinite after approaching infinity? This is the concept of the 'world'..."

Zheng Shu sighed in a low voice, and consumed the influence factor to just over 100 points, raising his "strength" to the highest level that can be achieved at this stage.

At this point, if Zheng Shu still didn't know where the owner of that breath was waiting for him, he could commit suicide on the spot.

"Directly invite me to meet outside the world? As a traverser, isn't my strength a bit too embarrassing?"

Zheng Shu felt the breath around his body with a little emotion.

If he could still find a way to break through the "universe", then he really didn't know how to cross the "world".

Because there were truly "infinite" numbers of cosmic bubbles around, it would be impossible to find the possible boundaries of the world.

"Fortunately, my body is awesome."

Zheng Shu opened the panel again and chose the function of traveling through the world.

One hundred points of influence factor were consumed. Under Zheng Shu's deliberate control, the power in his body was not stripped and restored to influence factor this time.

But even if he remained conscious throughout the whole process, Zheng Shu still could not understand the process and principle of the influence factor taking him out of the world.

In his perception, after paying the influence factor, he came to the outside of the world in the next moment.

"I still don't understand..."

Zheng Shu observed the situation around him and sighed helplessly.

He was still surrounded by an oval barrier composed of green light. The mosaic on the screen had indeed disappeared, but outside the barrier was a veritable void.

There was no concept of space, time, matter, energy, or even direction.

He had just left the world of the Blood Barrier Front, but there was nothing around him.

Zheng Shu felt like a little bug trapped in amber now, and there was no hope...

"!!!"

Suddenly waking up, Zheng Shu adjusted his state of mind with cold sweat on his forehead.

Fortunately, his spiritual cultivation was not bad, otherwise, his will would be crushed the moment he saw this true nothingness.

"So... what about that person?"

Zheng Shu was just about to look for it when he suddenly found something "attached" to his green barrier. After careful identification, he found that it should be some "information".

After hesitating for a while, Zheng Shu controlled the green barrier to let it in and tried to contact it.

The information contained a simple piece of knowledge, which was about the method of identifying outside the world.

Zheng Shu calmed down and used the influence factors on the green barrier as a medium. Through the methods provided in this knowledge, he turned a part of himself into pure information to contact the nothingness of the outside world.

Soon, Zheng Shu saw a different "scene" of this nothingness.

In this void without even the concept of space and direction, there is something almost endless.

That is pure "information" without any matter or energy.

"Use the disordered information as the background, and distinguish the ordered information from it as the node..."

Zheng Shu learned the method mentioned in the previous knowledge, distinguished the information by categories, and reorganized the collected intelligence in his mind.

So, he "saw" the "scene" outside the world again.

"Hiss... This... is so simple?" Zheng Shu couldn't believe that he had mastered the way to distinguish outside the world.

"It's that simple."

A stream of information came from the outside world and turned into a language that Zheng Shu could understand.

After a slight pause, the information flow as Zheng Shu's incarnation took the initiative to contact another information flow that conveyed information to him.

So, Zheng Shu "saw" a figure with his arms around him slowly "approaching" him.

There was also an egg-shaped barrier around the other party. The barriers of both sides touched each other but did not confront each other, but opened a hole to each other and connected with each other.

The two barriers are clearly separated, but perfectly integrated.

The figure's figure and appearance look almost absolutely perfect, as if they were divided according to the perfect golden ratio.

Zheng Shu was not sure whether the other party's original appearance was like this, or whether he had a special situation similar to his second skill on the panel.

"You can travel through the world, which means that you already have the ability to perceive the information state. The method I gave you is just to help you systematically integrate this perception in advance. Even without me, you can automatically understand it if you stay here for a longer time."

Compared with Zheng Shu's caution, the figure on the opposite side seemed quite cheerful and took the initiative to help Zheng Shu explain.

Sensing the other party's goodwill, Zheng Shu was stunned, and then he greeted the other party a little embarrassedly:

"Sorry, I kept you waiting for a long time."

"Ah, it doesn't matter. There is no concept of time here, so for me, I just sent an invitation, and then you showed up." The figure smiled and waved his hand, "My name is Xi Ke, just call me by my name."

"I am Zheng Shu."

After the two sides exchanged names, the atmosphere was obviously much more harmonious.

Zheng Shu thought for a moment and asked, "I wonder what you want to talk to me about."

"Ah..." Xi Ke smiled awkwardly, "To be honest, it's nothing, I'm just bored."

"Ah?"
