The heavens begin from the underworld

Soon after, the sky gradually brightened, and the sky was pale.

Lin Yang also left Qinghua University, one of the highest institutions of learning in China.

He didn't see many familiar people here, perhaps because he came here too early, and some people had not yet arrived at this institution.

Lin Yang had no interest in the various technologies of this era. Although Shengxu Earth was in the post-civilization era and had experienced a world war many years ago, the technological heritage was still there, and it was much more advanced than this era.

Only alien technology was worth Lin Yang's collection.

This was not a "worship of foreign things", but all life planets except Earth could be called alien.

Among the billions of life planets, Earth's technological level was by no means the lowest, but there were also countless technologies far beyond Earth's. The most obvious example was the Trisolarian civilization, which was about three light years away from Earth.

"Three light years..."

Lin Yang looked at the starry sky.

In the capital city where light pollution is serious, ordinary people can't see many stars when they look up at the sky, but in Lin Yang's eyes, even when it is almost daytime, the sky is still so bright.

The gorgeous galaxy hangs in the depths of the sky, beautiful and magnificent, making people dazzled and thrilled by the beauty of the universe.

Not long after, Lin Yang saw the Three-Body System among the stars.

At a distance of about three light years, it is not difficult to find a star system with three stars.

Lin Yang even saw the Three-Body planet whose trajectory was very chaotic under the gravitational force of the three stars.

Because the Three-Body star does not emit light and is covered by the light of the three stars, Lin Yang can hardly see the appearance of the Three-Body star and can only see the outline.

If it were in the underworld, this distance...

You can cross it with a thought.

Using the law to pry the power of the order of heaven and earth, you can easily compress billions of miles into one step with the law of space.

After this step, the world is far away, spanning billions of miles of starry sky.

But in the Three-Body World, such means are ineffective, and the Saint-level Evolvers cannot even form a Saint-level here.

After being unable to use the power of the order of heaven and earth for his own benefit, it became difficult for Lin Yang to take a step forward and directly reach the Three-Body Planet from the Earth.

In addition, Lin Yang also had concerns.

If you go to the Three-Body Planet by means that are too extraordinary, you will inevitably leave a track in the starry sky.

Such a track is invisible to ordinary people because it involves the deep mysteries of heaven and earth, but in the eyes of observers of advanced civilizations, it is too obvious.

Just like the footprints left on the soil, if you don’t look over, you can’t find it, but if you really look over, you can tell at a glance that someone has passed by.

According to the Dark Forest Law...

Such traces will attract attacks.

For example, in the ‘nearby’ of the solar system and the Three-Body System, there are observers called ‘singer civilizations’ by Lin Yang. Their duties are ‘cleaners’, specializing in cleaning up strange civilizations that have exposed traces in the starry sky.

The coordinates of the Trisolar Galaxy in the original time and space were exposed to the eyes of the Singer Cleaner because of the Earth. The other party used the cheapest cleaning method, accelerating a very small object to the speed of light, and then hitting one of the three stars of the Trisolar Galaxy, directly detonating the star.

Everything in the Trisolar Galaxy disappeared in the star explosion.

According to the theory, the closer the speed of an object is to the speed of light, the closer the mass will be to infinity. It is naturally easy to destroy a star in this way.

After the destruction of the Trisolar Galaxy, the Earth was also discovered because it had a connection with the Trisolar Galaxy, and the solar system also received a blow, not by the "light particles" that destroyed the Trisolar Galaxy, but...

not so cheap dimensionality reduction weapon "two-dimensional foil".

The solar system was thus beaten into two dimensions, becoming a two-dimensional plane in a three-dimensional universe.

Lin Yang was not sure whether it was the Singer Civilization's cleaner who made the solar system two-dimensional, or the cleaner of another advanced civilization.

The term "Singer Civilization" was because the cleaner liked to sing, and no one knew the real name of the civilization.

Just like insects are not worthy of knowing the name of God.

They were easily cleaned up by the gods, and no one knows which god did it.

According to the fantasy world, this is a group of crazy super powers who destroyed all external life without distinction. There is no situation where you are ignored just because you are an ant.

Even if you are just a mortal who has not embarked on the path of cultivation, or even just an ignorant beast...

If you are discovered, you will die.

Beasts may also evolve wisdom.

According to the situation in the Three-Body Universe, such behavior cannot be called crazy, but it is scary rational.

Because under the premise of the "technological explosion", any insect civilization has the probability of a sudden technological explosion, allowing the civilization level to leap and become a powerful enemy.

Because of the inconvenience of communication caused by the long distance, and the "chain of suspicion" of the complexity of biological thinking, no one can 100% believe in an alien civilization far away.

In human history, among the same race...

It is so cruel that genocide will occur, not to mention between different races.

At the same time, the reason why no god-level civilization came out to preside over "justice" is that...

The resources of the universe are limited, and if civilization continues to develop, different civilizations will sooner or later compete for these limited cosmic resources.

Although these "limited resources" are almost infinite in the eyes of insect civilization, in the eyes of advanced civilizations, limited resources are destined to be exhausted sooner or later.

After all, there are some special resources in the world that are non-renewable.

In this case, it is natural to get rid of all civilizations other than your own civilization to ensure that your own civilization can exclusively enjoy all resources. It is even possible to upgrade technology to an incredible level and create everything like a true creator, omniscient and omnipotent.

"If the solar system explodes, Gao Mouqiang will also have to sacrifice to the sky. Then I will never want to come to this world."

Lin Yang put away the scattered thoughts.

The level of Trisolaris in the three-dimensional universe is very high, let alone the peak of Trisolaris.

Not to mention the ten-dimensional universe in the pastoral era, where the speed of light was close to infinity, and there were all kinds of indescribable beauties, just look at the three-body universe after its "restart"...

Just let him not care.

In some theories of civilization that have been able to create small universes, the new universe after restarting must be higher than the four-dimensional universe at the macro level, and may even be higher than the ten-dimensional one in the pastoral era.

Furthermore, the most important point is that there may be more than one dimension belonging to time.

One-dimensional time is a straight line, with time running from one end of the straight line to the other.

With one more time dimension, there is two-dimensional time.

'"Even if time only has two dimensions, it will be flat rather than linear, with countless directions, which means we can make countless choices at the same time."'

Lin Yang recalled these original words.

'Making countless choices at the same time' is tantamount to cheating in every aspect, because in 'countless choices' you can always encounter the kind of result that has a probability infinitely close to zero, but it will really happen.

If the universe becomes like that, this will not be a special ability, but an instinct possessed by every creature in the universe. For example, creatures in the three-dimensional universe are born with abilities that creatures in the two-dimensional universe do not have.

if……

With one more time dimension, from two-dimensional time to three-dimensional time, this place will transcend heaven.

When I was imagining how wonderful the future of this world would be, another thought came to my mind.

"Can Gao Mouqiang survive until the new universe after the universe restarts?"

Lin Yang's mind was spinning, and he wasn't sure about this.

The 'universe restart' he mentioned is the goal of the 'Zero Ones'.

I don’t know whether the ‘Returners’ are one civilization or a group of several civilizations, but their technology is undoubtedly top-notch.

They want to restart the universe and return it to the pastoral era. They look like the oldest group that has survived from the pastoral era to this day. Likewise...

There is a high probability that it is also one of the culprits that changed the universe from ten dimensions to three dimensions.

The method of the Zero Returner to restart the universe is to continue to reduce the dimensionality of the universe, from three dimensions to two dimensions, then from two dimensions to one dimension, and then...

From one dimension to zero dimension.

One dimension is a line, and zero dimension is just a point.

This is also the origin of the name "Zero Returners", and what they really want to do is to make the universe fall to the zero dimension and then descend further.

It is a 'negative dimension' that is lower than zero-dimensional space and does not even have a point. It is also true absolute nothingness.

After all, not even a point exists, let alone anything else.

Time has long since disappeared at this moment, and when time appears again, it will be a new universe in which the universe has successfully restarted.

This kind of technology is beyond the imagination of insect civilization. Judging from the actions of the Zeroers, this is not some nonsense fantasy technology, but has actually been realized.

The Zero Ones' technology to reboot the universe by bringing the dimensions of space below zero has transcended absolute nothingness.

In contrast, using the energy in the universe to create a new planet, using the energy outside the universe to create a new universe...

Neither of them are advanced technologies. Both of them borrowed external forces. If you want to restart the universe with the concept of the Zero Returner in the Trisolaran world, there is no external force that can be borrowed.

Otherwise, the conclusion of ‘limited resources’ would have been broken long ago.

While Lin Yang's thoughts were ups and downs, the sun gradually rose in the sky, shining its light on the earth, but people mistakenly thought it was a glowing egg yolk.

It has been nearly ten hours since Lin Yang came to Trisolaris World.

In order to ensure that the earth would not become cold due to the 'traces' he caused, he decided to go to the Trisolaris Galaxy in the simplest way.

Fly over.

Don't use space abilities, otherwise it will leave temporary traces in space.

This is very similar to the traces left by the warp spacecraft activating the curvature engine to distort space and time.

After making the decision to fly to the Trisolaran Galaxy, the question returned to speed.

A distance of about three light years means that it would take about three years to fly at the speed of light.

Lin Yang simply cannot stay in this world for so long.

If the law is used even slightly, it will leave traces on the cosmic level, attracting attacks from the dark forest of advanced civilizations.

Seen this way, there is almost no solution.

Either risk exposing the existence of life on Earth and travel to the Trisolaran Galaxy by space-based means, or wait for return.

Flying at the speed of light even carries a lot of risks, because in the universe, there are too few objects that reach the speed of light naturally, and they are basically the actions of advanced civilizations.

In addition to the cleaning of "bugs", advanced civilizations are also engaged in cruel wars. Perhaps the "cleaners" of one civilization want to track down the location of the civilization behind Lin Yang and attack him after discovering Lin Yang flying at the speed of light.

"It's also a world full of depression."

Lin Yang sighed in his heart.

He looked at the crowds of people on the street that were gradually growing in number, and listening to their authentic accents, he could tell that they were carefree.

That's right, in this era...

How many worries can there be?

Especially for the people here, everyone firmly believes that everything will become better.

"There is no need to go to the Trisolarian system in person. After leaving the solar system for a certain distance, you can move forward with your soul."

"In this way, even if you leave space traces in the universe, it will not necessarily cause a blow to the earth."

Lin Yang pondered.

Even if he could distort space without scruples and go to the Trisolarian system, he was not prepared to go there in person.

It's not that he was afraid of being killed by some kind of technology of the Trisolarians, but that within the range that Lin Yang could reach, there was a "treasure" that was more valuable than the technology of the Trisolarians.

The location of the "treasure" was in the Oort Cloud, which was a spherical "cloud" outside the solar system, filled with a large number of comets.

In the Oort Cloud, which is far more than billions of miles away, there is a fragment of four-dimensional space.

After entering it, three-dimensional creatures can also have a four-dimensional perspective and see through everything in the three-dimensional universe from the bottom up.

For mortals, this is of great use, not to mention for evolvers like Lin Yang.

If he could remember part of this four-dimensional perspective, Lin Yang would be countless times faster than now when he comprehends the world.

To use a mysterious term, this is the "realm experience card". Even if the experience card expires, he can still remember some of the mysteries of that realm.

"What a pity. If I had come a few hundred years earlier, I would not have to go outside the solar system to enter the fragments of the four-dimensional space."

Lin Yang remembered that there were also four-dimensional fragments in the ancient earth, but with the passage of time, that tiny four-dimensional fragment completely fell into the three-dimensional universe and became a part of the three-dimensional space.

A woman once entered there and took advantage of the overwhelming advantage of the four-dimensional space having one more dimension than the three-dimensional space to perform "miracles" such as "taking away the treasures in the locked treasure chest from a distance" and "taking off the enemy's brain and heart out of thin air".

After feeling the fireworks of the capital at the end of the 20th century, Lin Yang's thoughts diverged and he thought of 1903 at the beginning of the 20th century.

That year, humans flew for the first time.

In 1947, supersonic flight was completed.

In 1969, we successfully landed on the moon.

It took only a few decades from the first flight to the moon landing. This is the technological explosion that the cosmic civilization fears.

In 1971, the human lander was successfully sent to Mars.

And hundreds of years after the Trisolaran Earth, humans whose basic physics was blocked by the sophon could still build space cities and space battleships.

As his thoughts fluctuated, after leaving behind a few soul thoughts, Lin Yang's figure disappeared. He ascended into outer space and headed to the Oort Cloud to find the four-dimensional space fragment.
