Until a scientific theory is confirmed, it is often called fantasy.

Just think about it.

If you are eternal in a ship of infinite energy, sail in an absolute direction in deep space.

Countless years later, you're surprised to find that you're back to where you started.

If it were you, what would you think?

At a time when the Earth had not yet been confirmed to be round, Gobulon accomplished a similar feat that rewrote human history.

Even now, there are still many people who think that the earth is flat.

However, to some extent, this idea is not impossible to achieve.

And the concept of parallel universes has been said countless times since its inception.

In the infinite universe, the area that a civilization can detect is limited, hence the famous saying:

Beyond the cone of light, there is nothingness.

Inside the cone of light, there is fate.

Therefore, it is called a parallel universe outside the detectable area, which is theoretically fine.

If that's the line.

If civilization stagnates, even outside of a planet, it can be called a parallel universe.

Of course, in a broad sense.

Parallel universes mean that countless universes exist with each other like bubbles, and someone's different choices will create a parallel universe.

As for the theories of the string universe, the membrane universe, the landscape universe, the multiverse, the virtual universe, etc., it is even more confusing.

When Great Xia was running the Galactic Spear, he accidentally exploded a hole in a parallel universe.

and successfully communicated with the unknown forces.

From this, we know.

The connection between the universes is not in some way an insurmountable taboo.

And it's in a parallel universe.

Once again, the human race has created an incredible feat.

With the essence of heaven and earth, shape a strong body, so that you can soar into the void, cross the universe, and the strong can even pick up the stars and step on the moon and go straight to the stars!

Such beings, they call themselves practitioners.

But such an existence is now in a desperate situation.

Tian Aolong followed the elders into the void, and the two of them were flying towards the core of the United States.

"Ao Long, don't be nervous, since the Supreme said that you are the chosen one, there must be a reason for him."

The elder has white hair fluttering, full of fairy spirit, and his longevity has passed for 10,000 years, and his name is Qi Kexiu.

"Boss..... I've just landed in the Foundation Building Realm, why did I suddenly become a cross-border candidate, it's not that I'm modest, I think it's better to ask for another high-minded ....."

The two of them were in space, casting a spell to squeeze space, flying faster than the speed of light in a curvature way, and they could vaguely see the brown nebula behind them.

Qi Kexiu shook his head and sighed, "Now that the astral realm has been broken, the Chaos Source Beasts have reached the Six Realms, it is impossible for our races alone to stop them, and we must find the help of beings outside the universe to survive this tribulation." ”

"Since the Supreme thinks you have such potential, why not give it a try?"

Tian Aolong was a little helpless, "But so many Tianjiao before, and even the great god of tribulation failed to succeed, how can there be no pressure just by relying on my small foundation." ”

Qi Ke was stunned for a while, speechless for the time being.

To be honest, he also has no bottom in his heart.

But who is the Supreme, that is the strong man who leads the human race to dominate the universe.

There are six vast worlds composed of countless galaxies in the astral plane, and the Supreme starts from a single planet and brings humans into space.

Defeated the demons, ghosts, immortals and gods, as well as strange races such as golems and void creatures.

The status of human beings in the astral realm was established, and the prosperous era of 10,000 years of prosperity began.

But just a thousand years ago, a terrifying creature suddenly struck outside the astral boundary, and the Supreme turned it into a Chaos Source Beast.

They had no fixed form, and the pitch-black substance was like mud tumbling, and low-level cultivators couldn't stop it at all, and countless races suffered countless casualties.

Thus began the war of resistance for nearly a thousand years.

Countless high-level cultivators all went to the edge of the astral boundary, using their numbers to block the invasion of the Chaos Source Beast.

But as time passed, the Chaos Source Beasts did not decrease, but more and more high-level cultivators died in battle.

Also due to the increase in the strength of the cultivators and the factor of low fertility, the appearance of cultivators is becoming less and less.

The strength of the entire human race began to regress.

If it weren't for the fact that everyone had a common enemy, I am afraid that the subdued demon clan and other races would be able to defeat the human race.

So a hundred years ago, after careful consideration, the existence of the Supreme decided to launch a cross-border request for help.

Based on various records and research, he succeeded in creating a cross-border array that would allow people to cross the boundaries of the universe and allow practitioners to reach the other side of the universe.

If it goes well, it should be able to bring Terran rescue to the astral plane.

After months of jumping and sailing.

Tian Aolong successfully reached the core of the astral boundary under the protection of Qi Kexiu.

The core of the astral realm is a strange dark orb whose existence sustains the entire astral sphere, and the Supreme Palace stands above it.

It was evident that a furious energy was drawn from the core and connected to the palace.

The area of the palace is not large, the diameter is only a thousand kilometers, and there are not many houses and buildings, and at this time, it is surrounded by countless Supreme Men, as well as a large number of onlookers and cultivators.

"Go, Ao Long, the rest of the road is up to you."

Qi Kexiu nodded and patted Tian Aolong's shoulder.

Tian Aolong looked at the appearance of the palace and nervously let his throat rumble.

A few years ago, he was just an ordinary student, if it wasn't for his qualifications and stepping into the immortal gate, he would probably still be living an ordinary life in the human world.

But now he actually came to the core of the astral plane, and he could meet the Supreme in person.

Tian Aolong carefully operated the method, allowing himself to see thousands of miles away, and sure enough, he saw the Supreme sitting cross-legged in the center of the palace.

At the same time, the Supreme opened his eyes, looked at him, and even smiled at him.

Tian Aolong suddenly closed his eyes and snorted.

Although it is not the past that cultivators would fight and kill when they met, there are also fighting methods that are triggered by what you are worried about.

Not to mention that he actually probed the Supreme in vain.

He turned his head to look at the master, needless to say, Qi Kexiu also felt the gaze of the supreme, "Stinky boy....."

However, although he scolded, he was not too harsh.

In any case, there is a high probability that his apprentice's trip will be more auspicious.

It's up to him to be willful.

"Ignorant boy, dare to snoop on the Supreme!?"

"This is a wild child from some planet in the human world, and it looks like he can't bear the task."

"The future of the astral plane, does it depend on this kid? I really don't know what the Supreme thinks. ”

"Shhh

In the discussion of countless practitioners.

Tian Aolong landed on top of the palace and walked towards the Supreme with his heart beating faster.

The Supreme also stopped sitting cross-legged, with a slight indifferent smile on his face, and opened his hands.

"Welcome, Chosen One."

"See... I've seen... Supreme. Tian Aolong stumbled in greeting.

Supreme, the supreme being of the astral plane, the embodiment of eternity.

Ten thousand years have passed, and he is still young, if he doesn't look closely, he is basically the same as Tian Aolong.

But the temperament he exudes makes people feel majestic and dare not look at it directly.

The Supreme nodded, and seemed quite satisfied with Tian Aolong.

"At first glance, your potential is still good, and you have the appearance of an emperor."

As soon as these words came out, the Quartet shook.

Emperor, strength is only under the Supreme!

Only the patriarchs of all races in the astral realm can achieve such strength.

Is this the Chosen One?

Countless people were shocked in their hearts, no one would doubt the vision of the Supreme, and the Supreme would not make any assertions.

Tian Aolong was even more stunned on the spot, he was just a foundation now, and the Supreme actually said that he could become the Great Emperor?

It's like talking to a schoolboy who is still struggling with how much 1000-7 is, and an adult runs up to him and says, "You'll solve the Riemann conjecture in the future."

A gust of wind blew across Tian Aolong's face, bringing him back to his senses.

In front of him is still the reassuring smile of the Supreme.

"Thank you, thank you Supreme for the compliment."

Tian Aolong got rid of distracting thoughts and kept his heart.

Regardless of whether he has the posture of a great emperor or not, there are more critical tasks to be completed now.

"You're good."

The Supreme nodded with satisfaction, he didn't notice a trace of complacency in Tian Aolong's heart.

Also, anyone who has the sign of the chosen one is basically the heart of this son.

Again, praise came from the mouth of the Supreme.

Now, no one will question this young man anymore,

The Supreme didn't say anything, and looked at Tian Aolong and asked.

"Tian Aolong, are you willing to step into the cross-border array for the entire Star Boundary, go to the unknown side, and find assistance for us!?"

This question contains the supreme power, and no one can lie against the will of the heart.

Only the most sincere and courageous people can answer in the affirmative.

Otherwise, it is a postponement or a fearful rejection.

Countless people looked at the boy expectantly, curious to see what he would answer.

And Tian Aolong heard the supreme's question, and his originally flustered mood calmed down.

"It is the Supreme who has created a peaceful and stable world for countless ordinary people to live in peace."

"It was countless cultivators who blocked the Chaos Source Beasts at the edge of the astral boundary, dedicating countless years to the peace of the astral realm."

"If I can dedicate my part to the astral plane, what thoughts do I have to refuse?"

Tian Aolong's inner thoughts flashed one by one, and finally said affirmative words.

"I do!"

Right now!

Countless great powers emanated from the palace, and the auspicious light floated in the void, which was so brilliant that people couldn't help but close their eyes and count their breaths.

"It's... This is! ”

A cultivator was shocked on the spot and couldn't believe it, "Astral Protection! ”

Brilliant auspicious light enveloped the entire palace, and everything turned into a white expanse.

"Sure enough, I didn't see the wrong person!"

The Supreme laughed.

Only one person has ever been granted the protection of the astral plane.

That is the love of the Supreme, the female sword god who fought for nine days.

It's just that under a general attack by the Chaos Source Beast five hundred years ago, the Supreme and her both died in battle.

Although the Supreme was able to reemerge from the core, she dissipated into the Six Realms.

Tian Aolong looked at his hands, and a strange power reached the depths of his heart.

His realm began to ignore the limits of his breakthrough and rose all the way.

Zhuji, Jindan, Yuanying, Mahayana, Tribulation, Ascension, Immortal... God.. Until the realm of the Great Emperor.

The coercion of space emanated from Tian Aolong's body, and he rushed out of the palace with a hundred miles of momentum.

Supreme, slowly approach.

Stretched out his finger and nodded Tian Aolong's head, and the vast amount of knowledge merged into his divine sea.

He also immediately understood the use of many supernatural powers, and gathered up the coercion emanating from his body, becoming a return to the basics.

"Thank you, Supreme."

At this moment, Tian Aolong understood many incredible things.

In addition to knowledge, the Supreme seems to have conveyed many mysteries that exist in the deep space.

Include details of cross-border development.

"And only you know these things, if ......"

The Supreme didn't say much.

Tian Aolong also knew what he was referring to.

When the predecessors crossed the border, they didn't know these things.

It's not that the Supreme doesn't want to tell, it's that they can't afford it.

There are certain mysteries in the universe that seem to be a taboo.

If the strength is not enough, or if you are not the one who hits, you will be attacked by the Great Dao if you learn such a secret.

Minor injuries can be severe.

In serious cases, the soul will be destroyed!

"Please start preparing for the crossover ceremony, I'm ready."

Tian Aolong exhaled a turbid breath, this was his last mortal breath.

Supreme nodded.

When I closed my eyes for a moment, I opened them, and my eyes were full of divine light.

"Guys, let's get started!"

The people around the palace were all ready after receiving the order.

Soon, the shape of the palace changed, and it spread out in all directions as if it were folding.

After a few hours, the entire palace stabilized.

In the end, it became a gossip-like existence, and the hollow position was the core of the astral boundary, and eight heavenly pillars a hundred miles wide and thousands of miles high were erected at the edge.

The Supreme Hetian Aolong stood above the core of the astral boundary.

This is the crossover array.

Then, the Supreme slowly ascended and came to the void.

The eight Heavenly Pillars surrounded tens of thousands of high-level cultivators, and they were about to sacrifice all their strength to connect the palace to the energy of the core of the Upper Star Realm.

"Start!"

The entire body of the Supreme was full of divine light, and the glow shot straight out in all directions, and the farthest was even hundreds of light years.

The area is shrouded in a realm of pure color.

In fact, the Supreme is the most suitable person for cross-border crossing.

But without him, no one would be able to activate the cross-border array.

The furious energy was fused and transmitted from the eight heavenly pillars into the cross-border array.

Then it was passed from the crossover array to the hand of the Supreme.

His eyes lit up, staring downward.

Tian Aolong suddenly felt a burst of pressure emerge, even if he became the emperor now, he would not be able to rise to the strength of resistance when he entered.

No wonder someone has said that under the supreme are all ants.

He was like a boat on the raging sea, losing all his strength like a mortal.

And slowly floated up.

After 30 days of this, the Astral Core began to flicker.

"Remember, even if you can't come back, don't forget the existence of the human race!"

The words of the Supreme reached Tian Aolong's heart lake, causing ripples.

"I'll take it to heart."

Time's up.

The Supreme smiled with satisfaction, and his entire body turned into particles and merged into the energy of the crossover array.

Then, it was as if a hole had been carved out in the core of the astral plane, and all the energy was gathered there.

Tian Aolong was falling, heading towards the core of the Star Boundary.

There's nothing spectacular about the view, it's like falling into a pothole.

Then he disappeared into the universe.

------Off topic------

Sorry for being late.

I don't know what transition to write, so let's have a parallel universe.

^_^

Finally, thank you to all of you who have been voting, as well as for the tips.
