The current Kunlun Void has not changed much compared with the Kunlun Void more than eight million years later, and time has not left a trace of scars on the jade-like stones.

The passage of time was more reflected in organic life, and after eight million years, the greenery, as well as the extremely tiny dust that was not visible in the sky, became fossils.

One day between 8 million and 7 million years before history, "Ragnarok" appeared.

Since then, most of the Kunlun Void space has been closed, leaving only some non-critical facilities barely maintained.

So much so that around 10,000 years before history, the Xia tribe in the Yellow River Valley of the Chinese Earth established a dynasty, and Nuwa only opened part of the abandoned space to be used as the capital of the Xia Dynasty.

As a result, primitive people were still using smashed stone tools in the first few hundred years, and cut people with a whin, and after a few hundred years, after entering the Shang Dynasty, civilization developed to the bronze stage.

There is no excess, in between.

And more than eight million years ago, Jiayu's consciousness, more accurately, was that he returned to the "soul" of the source of a long time at this time, but he had been thinking about a question.

In the end, do you want to tell the "Wa" that they and the other four warm-hearted civilizations are about to suffer the catastrophe.

They wanted to save the universe, so they traveled hundreds of millions of light-years to the solar system, waited for tens of millions of years, and ended up with nothing to do.

However, Jiayu did not dare to move.

If Jiayu was just an ordinary fishing wire, playing games, working, and delivering food every day, and going back to 8 million years, he might be the first to tell Nuwa loudly that you are going over!

Only those who are ignorant can be fearless.

However, Jiayu is also a top physicist in mankind, and he has an extremely deep understanding of the timeline.

Time cannot be changed and will not change.

The serious consequences of the butterfly effect are not something that ordinary people can bear.

Going back to the extremely distant past, if the five major interstellar civilizations escaped the catastrophe at the instigation of Jiayu, a little butterfly, then perhaps the demigods could reappear a million years after "Ragnarok".

Neanderthals would enter the evolutionary sequence as a second-level civilization.

Humans, as lower creatures, became domestic animals of the ancient Neanderthals.

After the demigod civilization was highly developed, modern Homo sapiens may be classified as a protected animal, with a marker for the demigods to study.

This is the only consequence of changing time.

Therefore, neither in terms of quantum mechanics nor in classical physics, he will not, and cannot change, time.

Jiayu couldn't open his mouth.

There was nothing he could do.

…………

In the bounce of "Wa's" consciousness, Jiayu knows some ancient stories.

In order to supply the energy construction needs of interstellar civilizations, the five interstellar civilizations destroyed the "Planet Abinis" between the orbits of Mars and Jupiter.

This is a large planet with a rocky texture, an alien wandering planet captured by the solar system, Abinis Star has been in the solar system for 2.1 billion years, but I didn't expect to be blown up by the virtual civilization that came from afar.

The asteroid belt that is now left is only the last remnant of this planet.

Jiayu listened to Nuwa's introduction and was stunned.

Blow up a planet?

It's not a movie, it's not a novel, and if you want to blow up a planet, it's not so simple to shoot a cannon and finish it.

In the lower layer of Kunlun's void, the "Forest of Fan Tong" - the space base.

Dozens of identical "Wa" opened silently, closing the "well" with huge walls, and the huge square mining spaceship like a skyscraper was moving in and out.

Here, there is no more dead silence after more than eight million years, huge transportation equipment runs silently, and the raw materials produced are continuously sent to other departments in Kunlun Zhixu.

Jiayu looked hot, but the silent "warehouse" was stunned.

"It turns out that this place was so lively back then......"

More than eight million years later, humanity once again entered the void of Kunlun, and outside the last well, Jiayu found the only working mining equipment.

A brick-like mining ship.

Inside, he inexplicably turned on a storage device, which played a scene of traveling at nearly the speed of light before crashing into Earth.

For Jiayu, this is the "hole" left in the timeline, and everything has to be filled.

Outside the nine wells, the asteroid belt.

Wa, who stood in the universe, left behind a mining spaceship, and according to Jiayu's needs, left a record image of the spaceship's arrival, after which the mining ship began to operate autonomously, independent of the entire Kunlun Void System.

This time, Jiayu carefully played a trick, and the image left by Nuwa was the scene when the main spaceship came.

The picture that Jiayu saw at that time should be the image recorded by the nanospacecraft that arrived first, and only this kind of spacecraft can fly at sub-light speed without entering the space bubble flight state.

In the state of the space bubble, time is stopped, and it is impossible to see the image of the concentration of stellar beams.

Jiayu wants to know if what he has changed after traveling through time is the future of this universe.

Until everything is clear, he only knows that the past has not changed.

The future is still shrouded in fog.

After completing this final "foreshadowing", Jiayu's work more than 8 million years ago in prehistory came to an end.

Possessed by the tail of "Nuwa", Jiayu enters the universe through the wellhead of the interstellar gate.

At the moment of crossing the "well", Jiayu suddenly had a strong premonition that his long past time was about to end.

He will soon return to the world of Earth more than eight million years later.

Jiayu's future energy and the long-past Nuwa energy had a strange interference, and some kind of uncontrollable physical reaction occurred.

The "well" itself, in the space-time continuum, can be regarded as a folding point of the space-time discontinuity of a wormhole, that is, at the position of the wellhead, the space-time of the universe is changed, time is zero, and space is zero.

So, Jiayu seemed to be sitting on a trampoline, and the moment she walked out of the "well", she ejected out, leaving Nuwa's mind for the first time.

He was "screened" out by the wellhead.

Jiayu staggered a few steps, turned around, and suddenly found that the position where he was standing now seemed to be eight million years later, when he had "again" stepped into this warehouse, ready to cross the "wellhead" and come out!

At this moment, the timeline coincides.

At this moment, Jiayu saw the whole picture of "Wa" from a third-person perspective for the first time.

At this time, "Wa" had already sensed Jiayu's departure, and she seemed to think that Jiayu was blocked by the complex high-dimensional space of "Wellhead".

Wa doesn't have any vocal organs, they don't need to communicate verbally, and Jiayu can see that "Wa" is opening her mouth and calling, but no sound waves are transmitted.

At this moment, the consciousness of "Wa", through electromagnetic waves, is shouting reluctantly.

Jiayu's current state is more illusory than a ghost, he doesn't know how to make a sound, and he doesn't know if he can move, he is afraid that his illusory figure will move a little, and he will leave this ancient world silently.

Soon, Wa quieted down, she turned around, her eyes lit up, and she saw Jiayu's appearance.

It was a body dressed in a beautiful diamond-cut armor, with no head in the head, just the face of a human ordinary fishing line, and it looked like it couldn't wake up.

Nuwa's true appearance is completely different from her visual perception in consciousness.

It's a very weird face.

Jiayu found that Wa's face shape did not conform to human aesthetics, and she was not a cat lady or a wolf girl.

Her face is relatively similar to that of a human, the canine teeth of the feline family are exposed, and the eyes are huge, but this pair of eyes are insect-like compound eyes, which are slightly scary.

A variety of different animal features are gathered on "Wa's" face, but there is a harmonious beauty.

Jiayu inhaled unconsciously.

"Wa" also seemed to see Jiayu's true appearance for the first time, and she smiled.

The eyes of the two have traveled through thousands of years.

It wasn't until a long, long time later that it overlapped again.

…………

After returning to the original timeline, Jiayu will occasionally recall the scene at that time.

This is a combination of Jiayu and Nuwa's images.

Nuwa was not wearing a diamond-cut battle armor at that time, but the beast-shaped Nuwa with a tail that she saw eight million years after Jiayu was wearing a battle armor, her head was blurred, and only her eyes were so bright, and there was no change in nearly 10 million years.

Moreover, the Jiujing wellhead of Kunlun Void does not have any multi-dimensional video recording equipment installed, which means that there is no hidden camera.

Na Jiayu "Before leaving", how did the last image of Nuwa be preserved?

It has been left until more than eight million years later, and Jiayu's reappearance is silently opened?

In this regard, Jiayu has a theory, when he returns to the timeline, the curve probability of his existence has shown signs of instability. That is to say, at this moment, Jiayu is a semi-closed time curve existence.

The probability of his existence is superimposed with Jiujing-Nuwa at this moment, and a closed time curve lasting 9 seconds is formed at this moment.

At this moment, Jiayu exists outside both Nuwa and Nuwa's bodies, resulting in the image of Nuwa wearing the only diamond-cut armor in the universe, but retaining her original appearance.

When the picture of that moment was recorded at the intersection of time and space in Jiujing, the closed time curve was announced.

Just waiting for the next trigger.

Eight million years later, Jiayu walked in ignorantly, opened the last "well", and when he was ready to explore, all the conditions were met again.

Nuwa eight million years ago saw Jiayu eight million years later.

Eight million years later, Jiayu was scared enough by the ripples of time and space left by the prehistoric ancient period.

This is just a theory, and as for whether this is really the case, Jiayu himself does not understand.

He saw Nuwa's smile and was about to say something.

Time traveled, and it came to an abrupt end.

Jiayu disappeared in the void of Kunlun more than eight million years before history.

The "well bar" of Jiujing dimmed, changing from a bright white marble color to a dull marble color.

Nuwa, the defender of the ancient spaceship, opened her mouth and moved her neck.

The position of her neck, a new organ is evolving, and it takes shape in an instant.

"Jia...... Fish? Thank you, from the end of time...... Return. ”
