Generally speaking.

Among the size classes of many celestial bodies in the universe, there are only star clusters between star systems and galaxies (river systems), and there is no 'star field' level.

But because of the presence of aura.

Because of the huge gap between the different areas of Reiki activity.

Therefore, the civilizations of the galaxy artificially divide them into four levels: none, low, medium, and high according to the calculation difference of the agility of each starry sky region.

And because the probability of the birth of life in a spiritless environment, and even the probability of further evolution of intelligent races and even intelligent races, is far lower than that of a spirited environment, and can even be said to be close to zero.

Therefore, the Spiritless Star Domain is also contemptuously called the Gray Domain by many interstellar civilizations, which means that there is no Light of Life, Light of Civilization, Light of Wisdom, and Light of Evolution (Aura).

For example, the solar system before the revival of the aura is the standard gray field.

At that time, in the eyes of many interstellar civilizations, the solar system at that time was only worthy of being used as weapons testing grounds, garbage dumping stations, or mineral excavation sites, and no one would even want to stay in these places.

The reason is that if the creatures that are born and live in the Spiritual Star Domain for a long time stay in the Gray Domain for too long, there is a high probability that they will slowly degenerate.

It is also because of this that many low-intelligence or non-intelligent cosmic beasts or interstellar beast groups will even be driven by instinct to bypass the gray domain as much as possible.

And the low-spirit-level star field in front of Mu Cang's eyes, in a strict sense, actually belonged to another huge globular star cluster that contained hundreds of thousands of star systems, but more than 99% of the area was a small part of the edge of the huge globular star cluster without a soulless gray domain.

Buzz –

The Unbounded Realm is activated in an instant.

Relying on this powerful superluminal speed of perception that completely transcended the three-dimensional space-time of the universe, Mu Cang, who was close to the low-spirit star domain here, explored the edge of the Spiral Clan's civilization in just one moment—only thirty-nine light-years away from the UFO civilization.

It is a binary star system.

Whoa, whoa, whoa—

The subtle and dense threads of perceptual undercurrent, which only exist in the deepest layer of the three-dimensional space-time structure of the universe, quickly covered this star system with a diameter of 16 trillion kilometers.

After coverage, high-dimensional perception instantly penetrates its trillion-kilometer-thick marginal nebulae and the meteorite belt that stretches for nearly a trillion kilometers, reaching the inner region of the core of this star system, which is full of rocky planets and gas giants.

Then, all the information contained in every millimeter of the surface and interior of these planets was probed by high-dimensional perception.

At the same time, the tens of billions of spiral clans that existed on various planets or were living, working, or resting like a large bullet yellow were also instantly immersed in the depths of their divine souls by Mu Cang unconsciously, and a layer of blazing light was plated on the surface of their root spirits, becoming another batch of spark donors of wisdom for him.

And all the complicated memories and knowledge information of the spiral clan collected from this star system were also transmitted through the boundless realm to Mu Cangyuan God who was standing in the distant starry sky dozens of light years away in an instant.

After quickly reading this ocean of information that was huge enough to burst the brain and soul of the Galaxy Overlord, he said with a little surprise:

"I didn't expect it to be a spiral life, yes, you can afford the name."

According to this information, the ocean shows:

This intelligent group called the Spiral Clan has a history of civilization for 10,000 years, with a total population of 185 billion.

Their spiral-shaped yellow bodies are composed primarily of anomorphic oxygenated derivatives based on crystalline hydrocarbons.

No hands, no feet, no eyes, but he is born with strong mental strength, so there is no obstacle to communication or catching soldiers and things.

Because of this special and extremely resilient physiological structure, this group is able to expand and contract quickly and move at high speed like a real spring, and can also absorb and convert a large amount of kinetic energy accumulated from the outside world.

Even newborn spiral fetuses can easily break through the sound barrier with their own elasticity without being hurt.

This also means that just this spiral fetus descended on the blue star before the revival of the aura, and it was not bad to easily kill King Kong, and it was necessary to gather a large number of troops and heavy firepower to encircle and suppress it in order to really kill it.

If it is those well-trained spiral warriors, they can burst out at a speed of more than Mach 10 anytime and anywhere, flying through the mountains and seas.

There is also a stronger Spiral Clan martial artist, who can even fly through the atmosphere into space with a single jump.

Relying on this powerful talent, the Ancient Spiral Clan naturally defeated countless ferocious beasts in the nature of the home planet to win the competition for survival, becoming the strongest species in the world.

After many years of dominating the ecological circle of the entire planet, the spiral tribe that gradually evolved into wisdom also experienced the primitive era, the classical era, the industrial age, and the aerospace age one by one, like many alien races, and finally ignited the light of fusion, and stepped into the infinite starry sky with curiosity and excitement.

After leaving the home planet, the spirals, who have always believed in self-evolution and the theory of species destruction, spent 1,800 years occupying all the planets in that star system step by step, and exterminated all extraterrestrial intelligent or non-intelligent species living on its surface.

In the end, the Spiral Clan, who conquered and controlled all the territory of the star system where they were located, managed to break through the vast nebula with great difficulty and set foot in the extraterrestrial domain, galloping to a wider range of stars.

And in the following hundreds of years, he discovered and studied the low-level Yongdao that was all over the depths of the spiritual realm of the star field but was completely cut off from the outer universe, but fortunately still functioned.

At this time, they also encountered in the spirit world a fierce enemy who would fight with them for thousands of years - the fossil tribe.

In the interstellar wars that have lasted for thousands of years, the two races have gradually occupied dozens of star systems, becoming one of the well-deserved overlords of this low-spirit star field.

Buzz –

Following the information 'given' by the Spiral Clan, Mu Cang's Unbounded Realm suddenly turned around, moved to dozens of light years away, and discovered the civilization territory of the so-called Fossil Clan.

"Fossil Family...... The name is kind of interesting. ”

Curious, his high-dimensional perception invaded the galaxy.

After passing through the sparse nebula, passing through the meteorite belt, and exploring the many planets in the system, Mu Cang repeated his old tricks.

Once again, the billions of so-called fossil families inhabiting this star system have all been 'normalized' in an instant.

At the same time, the vast river of information containing all the knowledge and memories of this race also returned to Mu Cang's primordial spirit through the boundless realm at the speed of light.

The message shows:

This group of intelligent people named the fossil family is a hundred light-years away from the home planet of the spiral family, and the history of civilization is nearly 10,000 years, with a total population of 92 billion.

To Mu Cang's surprise, this group was actually born and evolved from the bones of a large but long-extinct group of carbon-based giant creatures on their planet tens of millions of years ago.

"It's unbelievable that after being dead for so many years, they have become fossils and can still give birth to new life."

Mu Cang shook his head slightly and sighed, "The universe is really amazing. ”

In this information, although this group of sapient beings was born from ancient fossils, unlike the ancient giant creatures that were as large as mountains, the fossil families were small, even adults were the size of cats and dogs.

So although their speed is not slow, their physical strength is very weak.

As a result, the early fossil races were completely undominant in the brutal natural competition of the home planet, and were almost relegated to the end of the planet's food chain.

This dark period lasted for a long time.

However, perhaps because the brain structure of the fossil family is very different from that of ordinary creatures, and it presents clusters of lattice-like shapes, they are born with a strong sense of spatial geometry, and then they have established a relatively rudimentary but extremely complete mathematical system in that extremely ancient era when even the source of fire was mastered.

As the saying goes, mathematics is the foundation of all sciences, and it can also be called the mother of science.

Relying on this talent, the weak fossil tribe built a steam engine in the Stone Age, skipping the primitive and classical eras, and running into the industrial age.

After that, it was even more powerful all the way, and it rushed to the interstellar era in just over a thousand years.

Seeing this, Mu Cang outside the distant starry sky smiled dumbly:

"No wonder the ascending scale has risen so much, almost ten times the number of spirals under the same number of individuals, it turns out to be a full mathematician."

Soon after stepping into the interstellar age, the Fossil Race quickly came into contact with the Spiral Race, which was completely different from their own in appearance and concept.

The Spirals advocate the exploration and use of every corner of the starry sky, arrogantly regard themselves as the developers and masters of the universe, and have a strong desire to conquer other races.

The fossil race advocates evolution and creation, but does not reject the use of force to protect themselves.

At the same time, they also believed that there was some mysterious and ancient impersonal god in the universe, and that it was this god who created and formulated the rigorous rules of mathematics.

Therefore, they are equally arrogant in believing that they possess paramathematical talents simply because they are the chosen people of the Creator God and are born to protect life and nature in the universe.

The two races' very different philosophies, as well as the competing interests in the vast starry sky, have led to a huge conflict between them.

However, due to caution, the two clans did not start the war lightly at first.

It wasn't until one expedition to the edge of the unknown Grey Field that the research ships of the two races accidentally exchanged fire.

After the arrival of the follow-up forces of the two clans, the exchange of fire developed into a local battle.

The battle ended quickly, and both sides suffered some losses.

Although the top leaders of the two ethnic groups had the idea of peace talks after the incident, due to the great differences in ideology between the two communities, even if the two sides were militarily comparable, they could not reach an agreement on peace talks.

Eventually, the war inevitably broke out, fueled by the boiling desire to fight within the civilizations of both sides.

From the very beginning, the war was unusually tragic.

In order to complete the battle, the two races have all put the most cutting-edge technology and the most brutal weapons on the battlefield, which also makes the intensity of war in interstellar space remain high.

Over time, the scale of the war grew.

Hundreds of starships were destroyed, billions of lives were lost, but the two sides still couldn't tell the winner.

Time passed, and the war lasted for a hundred years.

During this not short period of time, both sides suffered heavy losses and long-term torment.

Eventually, the two communities began to try to negotiate peacefully.

And after many painstaking efforts, the permanent peace agreement was finally signed by the supreme leaders of the two communities at a grand ceremony.

In the terms of the agreement, the two sides stipulated that no further war would be wagered and that they would always maintain mutual respect and tolerance for years to come.

But at this moment, a large Demon Brain Clan scientific research ship passing by accidentally collided with an invisible giant antimatter torpedo left behind by an ancient unknown civilization in deep space not far from this planet, and detonated the mutilated torpedo array that the ancient civilization had somehow 'buried' in the interior of this star system.

In the end, the Demon Brain Clan's research ship escaped with 'serious injuries', and the surface plate of the planet also suffered great damage.

Naturally, the supreme leaders of the two communities who had just signed a permanent peace agreement and their respective high-ranking members of their teams were all dead.

And so, the war began again.

The difference is that this time it has joined, or passively joined, a group of new forces, those 'new demon brain clans' who have been resurrected by the death of the spirit crystal dark matter - the UFO clan.

Although the number of individuals in this new force is too small, the foundation is very thin.

But because of the military technology that is enough to crush the two races for several generations, as well as the powerful and unsolvable ability to control the mind.

At the beginning, with only a broken ship that had been repaired for another three years, the XCOM could still barely compete with the starfleets of the Spiral and Fossil races.

As a result, the war between the three tribes, which had lasted for thousands of years, slowly began.

"It's a bit interesting, but it's still a snail fight in essence." Mu Cang sighed leisurely.

Without the slightest hesitation, he walked directly towards this low-spirit star field.

Whoa, whoa, whoa—

Mu Cang's huge body swept across the starry sky, rolling up layers of space-time waves.

In just half a step, he penetrated a layer of interstellar dust clouds that spread on all sides, but were so thin that they were only a few trillion kilometers thick, and entered the periphery of the star field.

As soon as he entered, Mu Cang encountered dozens of star systems blocking in front of him.

At this moment, these star systems looked like dark loose smoke rings the size of a Coke bottle cap.

Fragile, almost with a wave of the hand.

Buzz –

The Unbounded Realm swept away, and in an instant, these star systems were swept away.

Extracting and analyzing all the information contained in it, Mu Cang said a little indifferently:

"There may be some low-intelligence life forms, but there is no spiritual brilliance to shine and useless."

Without stopping, he took an indifferent step forward and ruthlessly smashed these small smoke rings.

Boom Boom Boom –

Dozens of star systems scattered all over the starry sky were like the end of the world, and they were instantly knocked into collapse and disintegrated, turning into a stream of majestic heat energy that was swallowed up by him, and not even a single atom was left.
