Volume 3 Chapter 257 Returning to the Past 20,000 Years Ago
"The universe-traveling fortress we are looking for? Could it be here?" Nanzhu looked up at the sky in surprise, imitating Lin Xu, but saw nothing.
"It's right here. I didn't expect that he would live in seclusion near the universe-traveling fortress." Lin Xu also felt a little emotional.
"If it's here, why didn't we see it when we came here just now?" Nanzhu asked puzzled.
"He covered it up with a high-dimensional characteristic space. I originally thought that he set up this high-dimensional characteristic space to hide something inside, but I didn't expect that it was to cover up the universe-traveling fortress, and at the same time to delay us now." Lin Xu replied.
As they were talking, several people had already come out of the valley and arrived on the vast plains outside. The environment with birds singing, flowers blooming and pleasant scenery was in stark contrast to the previous environment of yellow sand.
Even Lin Xu and others couldn't help but take a few more glances.
"Is this reversing cause and effect and changing history? It's really incredible." Lu Yao sighed.
At this time, several patrol boats in the distant sky had discovered Lin Xu and his group. Immediately, those unmanned patrol boats rushed towards where Lin Xu and his group were.
At the same time, a radio warning sounded.
"Warning, unknown personnel have entered the planet's protected area. Please provide relevant documents to prove your identity. You have the right to remain silent until your lawyer arrives."
"Let's go." Lin Xu ignored the patrol boats in the sky. He paused on the ground, then soared into the sky and went into space.
Miss Qiu, Nanzhu, Mu Xiyue, Lu Yao and Arisa all followed, and in the blink of an eye they left the patrol boat below behind.
As the scenery below became smaller and smaller, scenes appeared in the sky that had never been seen before on this planet.
A huge star ring surrounds the planet, and countless intelligent life forms live in it. They travel between the ground and the star ring through densely packed space elevators, forming a vibrant civilization.
And all of this clearly did not exist before Lin Xu and others came to this planet.
At that time, this planet was just a gloomy planet covered with yellow sand.
Now, although the stars are still at the end of their lives, the entire galaxy looks full of vitality. All the changes are due to the existence of these intelligent life forms.
They transformed the planets in the galaxy, and Lin Xu even noticed that they built huge doomsday spaceships on the planets at the edge of the galaxy. That was their means of preventing stars from suddenly exploding into supernovas.
A star that is reaching the end of its life may begin to explode as a supernova at any time. Once this happens, the intelligent life on the doomsday spaceship will be the seeds of this civilization.
Of course, they are also building more giant spaceships and planning to migrate to galaxies outside the galaxy.
However, at the edge of the universe, due to the expansion of the universe, the distance between galaxies is much greater, so galaxy migration has become more demanding.
But it doesn’t matter, they are not desperate but full of hope.
However, it was this vibrant hope that made Lin Xu and his group, who were near the star ring, feel depressed.
Because everything here is based on the fact that Rumen changed the planet, a historical process of an intelligent civilization that should have been destroyed in history.
Rumen modified the history of this planet so that this intelligent civilization did not perish in a disaster, but instead flourished and developed. This led to the creation of this planet and even this galaxy today.
But all this is just a beautiful soap bubble that will burst if blown.
Because with Rumen's ability, there is no way he can make such a change in the real universe. The huge corrective force of the universe will completely correct his attempt to change history.
Therefore, this change of his was only carried out under the protection of the high-dimensional characteristic space for this galaxy.
He placed this galaxy under the protection of a high-dimensional characteristic space, temporarily isolating it from the cosmic correction force. Therefore, he could easily change the history of this galaxy and allow a race that should have died out in history to develop.
"Lord Lin Xu, if we break this high-dimensional characteristic space and let everything here come into contact with the outside universe again, will this civilization disappear directly?" Nanzhu looked at the extremely busy scene above the star ring and suddenly felt unwilling.
This civilization must have spent countless efforts to build this huge star ring and leave traces on the planets in the galaxy! Perhaps they have countless astronauts who died on the way to explore the universe, and countless heroes who died at the critical node of saving civilization. But all this is actually meaningless. When this place reconnects with the outside universe, everything will be corrected. Nothing has happened, including all their efforts to develop civilization from scratch, which can't even leave a trace in the universe.
"No, maybe this is also an opportunity." Lin Xu said after hesitating for a moment.
"Opportunity?" Nanzhu was puzzled, and the others were also confused.
Only Arisa seemed to have thought of something.
"So, this is his purpose? I was wondering how he could trap us in such a high-dimensional feature space. It turns out this is what he was thinking." Arisa said with sudden enlightenment.
It is almost impossible for ordinary races to break a high-dimensional feature space, and they cannot even discover the existence of high-dimensional feature space.
It may be a little difficult for god-level civilizations, but for Lin Xu, Miss Qiu, Nanzhu, Mu Xiyue, Lu Yao and even Arisa, breaking the high-dimensional characteristic space is almost a simple matter. So how can Lumen realize the idea of delaying time by relying on this high-dimensional characteristic space?
"Yes, this opportunity is rare, so let's give him some time." Lin Xu nodded and decided.
"Lord Lin Xu wants to take this opportunity to master the ability to utilize high-dimensional power and reverse cause and effect?" Mu Xiyue reacted all at once and said with sudden enlightenment.
"Yes, reversing cause and effect does require certain skills, and apparently Rumen has left enough skills here. I just need to follow them and truly modify the history of this civilization so that it can be recognized by the universe in the real universe. This means I have mastered the ability to reverse cause and effect. I don't know when I will have such an opportunity again, so let's give him some time!" Lin Xu decided.
"So, this civilization can truly continue to exist? Then what should we do?" Nanzhu said excitedly.
"You don't have to do anything, just wait. I need to first determine which important node in the history of this civilization was modified, allowing this civilization to continue." As he spoke, Lin Xu slowly closed his eyes, and in an instant his high-dimensional vision opened, and he began to examine the galaxy obscured by this high-dimensional characteristic space.
He tracked the traces of Rumen's modification of history and soon found a way to use high-dimensional power to read history.
I have to say that although in terms of high-dimensional power, Lumen and Lin Xu are like a drop of water compared to the ocean, but when it comes to the subtle control skills of high-dimensional power, Lumen has indeed brought the skills to the extreme. In some aspects, even Lin Xu can't compare with him.
So Lin Xu began to use high-dimensional power to look through the history of this galaxy.
Soon, at some point 20,000 years ago, the key node that changed the fate of intelligent life on this planet was found.
"Found it." Lin Xu slowly opened his eyes and said.
"Found it? What should we do next?" Nanzhu seemed even more excited than Lin Xu himself.
"Go back to the past 20,000 years ago and fix the changed history with my own hands." Lin Xu replied.
"Oh, go back to the past twenty thousand years ago. What? Go back to the past twenty thousand years ago?" Nanzhu's voice suddenly became high-pitched.
"It's still possible to do this?" Mu Xiyue was rarely surprised.
"Yeah, I didn't think it could be like this before. No wonder Lu Men was so sure that I would be delayed here. Going back to the past and seeing it with my own eyes, the temptation is really great." Lin Xu sighed.
The next moment, he waved his hand, and high-dimensional power enveloped the bodies of several people present.
"Let's go and see what happened 20,000 years ago."
In an instant, the scene around them began to change rapidly.
Everything around turned black and white, like an old black and white silent film, and time began to flow backwards.
The star ring that had already been built was shrinking rapidly, as if it was being dismantled quickly until it disappeared.
Five thousand years ago, intelligent life began to build star rings. They excitedly laid out the first star ring base in space, a huge substrate ten thousand meters long.
Time continued to flow backwards, and came to eight thousand years ago. Intelligent life created a kilometer-long warship for the first time, sailed to another planet in the galaxy, and began colonization.
The time finally came to ten thousand years ago. Suddenly, a large area of the originally twinkling starry sky dimmed. Lin Xu stared at that area, stunned and a little dazed.
"Lord Lin Xu, what's going on with that starry sky?" Nanzhu asked puzzled.
"That place should be where humans passed through ten thousand years ago, right?" Lu Yao thought for a moment and guessed.
"That's right, that's an area I can't get close to. It's also an area where history is completely fixed and cannot be modified at all." Lin Xu sighed.
He can modify history at will, but he cannot touch any history involving human beings.
Even if we simply go closer to the area where humans lived during that period of time ten thousand years ago and see human history with our own eyes, we cannot do the things that were done ten thousand years ago, because the history involved in human beings has been completely anchored and cannot be modified or even touched.
Lin Xu couldn't even imagine how much those humans in higher dimensions paid in order to pull him out of the Earth ten thousand years ago and throw him ten thousand years later.
That is the home planet of mankind, the Earth, which can also be said to be the most stable region in history. Any effort to modify the Earth's timeline will never be allowed.
Because a small modification to the Earth billions of years ago may make it impossible for subsequent humans to be born on Earth.
The chain reaction caused by this may even cause the collapse of the higher dimension. After all, humans are now high-dimensional creatures that have been incorporated into the higher dimension.
Therefore, human history cannot be modified. This is not only due to the rules of this universe, but also the rules from higher dimensions.
Soon, the time that flowed backwards crossed the time node ten thousand years ago, and the twinkling starry sky appeared again, and there were no dim areas. This meant that Lin Xu could go to these areas because there were no people there now.
However, it is still difficult to modify the history of that area, because humans will pass through that area in the future and anchor the future of that area. So it is not that Lin Xu cannot modify the history of that area, but he can only modify it in a small range and must not interfere with future humans, otherwise his modifications will be invalid.
However, all this has nothing to do with Lin Xu for the time being. The scene around him continues to flow backwards like a black and white silent film.
Fifteen thousand years ago, the intelligent life forms on this planet were cheering as their first artificial satellite began to orbit the planet.
Time continued to flow backwards, and it officially came to 20,000 years ago, when the flow of time finally stopped.
Everything around was still like a black and white silent movie. Lin Xu, along with Miss Qiu, Nanzhu, Mu Xiyue, Lu Yao and Arisa, landed towards the planet.
The scene around me was like a frozen black-and-white silent film. Everything was filled with a sense of unreality, as if I was watching an old movie.
Nanzhu couldn't help but approach Lin Xu, while Lu Yao was landing while muttering, "Incredible, too incredible, what is the principle behind this? No, I have to record it and calculate it carefully later, calculate it carefully."
Lu Yao was holding a pen and paper and recording everything in a muffled voice. Mu Xiyue and Arisa, who were also seeing this scene for the first time, followed Lin Xu for fear of getting lost and being forgotten in the cracks of time, never being able to go back.
Only Miss Qiu followed Lin Xu consistently, but her rapidly flickering eyes also revealed her inner unrest.
In this way, the group descended rapidly towards the ground of the planet below, and soon the scene on the planet came into view.
Twenty thousand years ago, although there was still a large amount of vegetation growing in this world, nearly half of the planet was already covered with yellow sand.
One can imagine how difficult it is to manage it to the state where it will be covered with lush vegetation 20,000 years later.
And these 20,000 years ago, this planet was still in the era of city-state civilization.
Intelligent life forms were divided into countless ethnic groups, occupying city-states on the oasis and fighting each other.
Relying on his high-dimensional power to sense key historical nodes, Lin Xu quickly found a battle taking place below that would affect the future of this civilization.
There were two armies facing each other on the plain.
On one side, a large number of infantrymen were lined up with guns, fighting against the nomads on horseback on the other side.
No matter how the mounted nomads harassed and attacked them, the infantrymen advanced step by step and calmly responded to the nomads' attacks.
However, at this moment, the leader of the infantry camp suddenly stumbled and was tripped by an arrow stuck in the ground.
Suddenly, the entire infantry camp was in chaos as their leader fell.
In the classical era, the leader of an army was very important. Otherwise, there wouldn't be the saying of beheading the general and seizing the flag. Once the leader fell, the troops under his command would immediately be shaken. If the enemy took advantage of the situation and killed them, a great defeat was inevitable.
The nomads on the opposite side obviously seized this opportunity.
Taking advantage of the infantry's hesitation, a large number of nomads rushed up on horseback.
Then things got out of control.
At this moment, Lin Xu, who was high in the sky, reached out and gently moved the black and white scenes around him.
So, history changed, and the leader was not tripped by the arrows, but commanded his army to repel the nomads.
Afterwards, the leader led his city-state to develop quietly and accumulate strength.
It was not until his grandchildren, relying on the strength he had accumulated, that they seized control of several surrounding city-states.
Then, several hundred years later, his descendants established a vast empire.
The history of this planet and even this galaxy began to change from then on.
"It's incredible." Mu Xiyue sighed.
"Yes, it was just a trip, such a small thing, but it actually affected the future of a civilization and caused an intelligent race that could have developed a magnificent civilization to disappear in the long river of history. It also caused this planet to completely decline 20,000 years later and became no longer suitable for the reproduction of civilization." Lu Yao also sighed.
"The development of civilization is the accumulation of many small things, and there is a lot of randomness. In many cases, luck is also a part of strength." Arisa said, glancing at Lin Xu.
In a sense, the fact that humans have been able to reach this point is also a manifestation of their good fortune.
Time began to flow forward again, and the surroundings were still a black and white silent film. Lin Xu and others watched the subsequent developments in silence.
With the change of that small time node, everything in this galaxy has changed.
People established modern civilization, launched satellites, built spacecraft, colonized every planet in the galaxy, and even built huge star rings.
Only when passing the time node ten thousand years ago again, the starry sky became dim, and Lin Xu's mood became gloomy again.
But then the starry sky became bright again.
Lin Xu felt the enormous pressure that was fed back after the higher-dimensional power modified history. It was the effort from the cosmic correction force to put the universe back on track.
Previously, Lumen relied on the high-dimensional characteristic space to temporarily control the cosmic correction force, but Lin Xu wanted to completely modify and fix the history of this galaxy, so naturally he did not isolate the cosmic correction force.
Immediately, he felt the backlash from the corrective force of the universe.
It’s a pity that even the force of cosmic correction is powerless in the face of human’s high-dimensional rules.
In the end, the cosmic correction force did not change Lin Xu. Instead, it was forced to change itself to adapt to everything after Lin Xu modified history.
At this point, a completely new history was fixed and recognized by the universe.
Lin Xu also mastered the method of changing history and reversing cause and effect.
