Metaverse Evolution

Inside the spaceship, the feathered serpent acted as the atmosphere group, running around in the spaceship, adding a lot of vitality.

Chu Fei's several 14.9 advanced clones each performed their duties.

Some were responsible for supervising the safety of the route, some were responsible for the calculation of the route, and some were responsible for the monitoring of the spaceship; while Chu Fei's main body was responsible for cultivation. The value of the clones was squeezed to the extreme by Chu Fei.

Among the many clones, the clones responsible for the route were the most.

Chu Fei is now using the naturally formed gravitational string, which has not been artificially combed. Such gravitational strings are full of dangers, just like reefs in natural waterways.

In addition to the debris in the gravitational string, there are also gravitational strings themselves.

From the Shenlong Galaxy to the Yunlong Galaxy, the straight-line distance is 83 light years, and the estimated voyage is 90 light years. At such a long distance, Chu Fei cannot explore the gravitational string conditions of the entire journey, that is, he cannot directly locate the gravitational string of the Shenlong Star to the Yunlong Star.

The interstellar travel method adopted by Chu Fei is - adjacent star positioning, which is a kind of segmented positioning.

From the Shenlong Galaxy to the Yunlong Galaxy, there are more than 40 star galaxies of different sizes in the middle - they are not arranged in a straight line, but randomly distributed up and down and left and right.

Chu Fei needs to choose an "excellent" route from them.

The larger the mass of the two stars and the closer the distance between the two stars, the wider and more stable the gravitational string in the middle.

But for some red giants and blue giants, you have to be careful. The gravity is too large, and the gravitational string is not stable - just like the waves turning into a tsunami.

But in the interstellar, the distance between two massive stars is not necessarily close, and the state of the nearby stars is not so perfect.

Now Chu Fei is heading towards a star 7 light years away, which is considered a "white star".

The color of the star can be roughly divided into four levels: red, yellow, white, and blue. The smaller the volume, the dimmer the light - reddish, and the larger the volume, the brighter the light - blue.

The solar type belongs to the "yellow" range.

About ten times larger than the sun, it is the "white" range. Bigger is a blue giant, and blue giants are unstable. Red giants belong to the late stage of stars and are more unstable.

The stars selected for positioning in the interstellar space were all emitted many years ago. Who knows what the situation is now? Maybe a supernova explosion will happen in a few years; although this possibility is small, it is still possible.

So try not to choose blue giants for interstellar travel. Yellow and white main sequence stars are the main choices.

There are also multiple star systems such as binary star systems and triple star systems, which are also unstable and must be avoided.

After such screening, Chu Fei finally chose only 12 star systems. The distance between these 12 star systems is 6 light years at the closest and more than 14 light years at the farthest.

It is expected that the entire route will present an irregular spiral fold line, with an overall range of more than 90 light years.

The spacecraft continued to accelerate and arrived at the first target galaxy in just 5 months - Chu Fei was still cautious and did not accelerate the spacecraft to the limit, only maintaining 80% of the theoretical limit.

Although the hadron material is powerful, it is still a mortal after all, and the hadron materials at present are all salvaged from stars and processed, which is like digging nugget gold from nature and slightly processing it. Such materials have a lot of impurities.

After entering the galaxy, the spacecraft began to decelerate crazily again, and kept reducing the speed to 50 kilometers per second before jumping out of the gravitational string.

It is impossible to jump out of the gravitational string at superluminal speed, and the real world does not support superluminal speed. If you have to do this, then the spacecraft will be "smashed" into photons, and even the atomic nucleus cannot be maintained.

After the spacecraft jumped out of the gravitational string, it slightly adjusted its speed and then steadily suspended in the current star system. Chu Fei began to observe the distant galaxies and look for the next stage of the target.

At the same time, he was also observing the current galaxy.

At present, this galaxy is desolate, the white main sequence stars are already very violent, and the solar storm and the tyrannical electromagnetic force continue to wash the entire galaxy. There are two rocky planets bare, and the rest are gas planets.

Not finding anything good here, Chu Fei calculated the next gravitational string, and the spacecraft accelerated again, still using the gravitational force of the star to accelerate, and drilled into the gravitational string again.

Unconsciously, more than six months had passed, and Chu Fei drilled out of a galaxy again, and it was another desolate galaxy. In fact, it has been proved that there are only a few galaxies that are truly suitable for the existence of life, even galaxies that are suitable for transformation.

After re-calibrating the direction, Chu Fei frowned.

It is 14 light years away from the next target galaxy, which is too far away. After rigorous calculation, it was found that the gravitational string is not stable enough. According to Chu Fei's current formula, there is a possibility of a break in the middle of the gravitational string.

If the gravitational string breaks outside the star system, it will be three or five light years away from the nearest star system, and then it will be over. If the spacecraft flies in normal space, it will take 20 years to fly one light year, and three or five light years is sixty or seventy years.

Although the current spacecraft is made of hadron materials, Chu Fei dare not say that the spacecraft can fly intact for such a long time.

It is precisely because the spacecraft is made of hadron materials that the spacecraft cannot be repaired.

Chu Fei certainly has spare parts, but repairing a spacecraft is not a simple matter.

After calculating for a while, Chu Fei sighed and found that he didn't dare to gamble. So, he could only take a detour.

He locked the telescope on the surrounding starry sky to search for targets and found the "springboard". But in this case, the journey is estimated to be about five light years longer.

"Forget it, it's better to take a detour than take a dangerous road."

After checking the direction, Chu Fei set off again. But this time, just after the formation was halfway through, Chu Fei found "traces of life" in the gravitational string!

To be precise, the spacecraft detected the unique fluctuations of life energy, and it was very strong, and the concentration even exceeded the data of Venus.

For now, Chu Fei found that life can only be born with life energy. Life energy has a unique continuity, or a super-dimensional attribute.

So if life energy is suddenly detected here, there is a high probability that life will be born.

The life energy of Venus is very rich, enough for cultivation, thanks to the fact that the star of the Tenglong galaxy is a white dwarf.

Now the life energy here is even more than that of Venus, which makes Chu Fei interested.

The place where life was discovered is the middle of this section of gravitational string. At this time, the world outside the gravitational string is pitch black, and the nearest star is 2.2 light years away.

But here, the gravitational string expands, like a river entering a lake.

From a long distance, Chu Fei discovered a planet.

Chu Fei became interested in discovering the "gravitational lake" in the gravitational string, and even discovered a planet and rich life energy.

There was still plenty of time, and with his cultivation level high enough and a clone, Chu Fei naturally wanted to go and take a look.

The spacecraft began to slow down, but the speed was still too fast. After more than ten days of deceleration, the spacecraft passed the planet at 3.4 times the speed of light. Chu Fei could only continue to slow down and prepare to turn around.

But at the moment of passing the planet, Chu Fei also detected a lot of information.

This is a "gas planet" with a diameter of 2.5 times that of Jupiter - a diameter of about 360,000 kilometers, a mass of about 16 Jupiters, and a surface temperature of 3 degrees Celsius.

There is a brown-red light on the surface of the planet, and the whole is like a piece of charcoal buried in ashes, with a dim light.

After analysis, Chu Fei was somewhat surprised that this was actually a star, the legendary brown dwarf!

According to scientific theoretical calculations, if the mass of a star reaches 13 times the mass of Jupiter, it may cause nuclear fusion in the core of the planet and generate weak heat. Here we are talking about mass, not diameter or volume.

This kind of star body that has just been able to carry out nuclear fusion has a very high core temperature, but a very low outer temperature. Theoretically, the outer layer of this star body is very suitable for the existence of life.

And this planet seems to meet this condition. The surface temperature is 3 degrees Celsius, and the temperature of the nuclear fusion reaction must be at least 4 million degrees.

Outside the core, the temperature will drop sharply. After a simple calculation, Chu Fei believes that the temperature of this planet can be maintained below 40 degrees after 160,000 kilometers from the core, until the surface of the planet.

In other words, according to preliminary estimates, this planet has a life layer at an altitude of 20,000 kilometers! The volume of its living space is a million times that of the earth!

A brown dwarf is equivalent to a million earths. This is why the Yanhuang Federation has been looking for brown dwarfs and trying to artificial brown dwarfs.

You know, the total number of life planets owned by the Yanhuang Federation at its peak is estimated to be only in the millions.

So when seeing a brown dwarf, Chu Fei must slow down and observe it. Even if it takes three to five years, it is worth it.

The spacecraft slows down, then accelerates in the reverse direction, and slows down again when it approaches the planet. In the end, it took Chu Fei four months to finally get close and circle around the current planet.

At this time, Chu Fei conducted a detailed investigation of the current planet:

The diameter is about 357,000 kilometers, 15.89 Jupiter masses, 6.37 times the standard gravity of the earth, and the surface wind speed is 2.6~417 meters per second;

The reason why the diameter is not accurate is that it is a gas planet at present. There are differences in the definition of the surface of a gas planet in the scientific community.

Some people use the air layer corresponding to the standard atmospheric pressure of the earth as the surface; some people think that the air layer corresponding to the atmospheric pressure of the earth's stratosphere should be used as the surface. Of course, some people use the state of near vacuum at an altitude of 80 kilometers on the earth as the surface.

Here Chu Fei chose the first measurement method, that is, the air layer corresponding to the standard atmospheric pressure is used as the surface. This definition has an advantage, which is more suitable for the thinking habits of earthlings and is easier to understand.

If calculated in this way, there are more than 50 kilometers of "atmosphere" outside the surface of this planet.

The spacecraft is flying around at an altitude of 10,000 kilometers from the "surface", and the orbiting speed is about 106 kilometers per second.

Then Chu Fei opened the hatch from the back of the spacecraft and threw a probe to the planet. Well, there was no probe on the spacecraft, but there was a space shuttle, which was used as an "escape spacecraft".

Now that we have encountered a brown dwarf, it is completely worth it for Chu Fei to use a space shuttle.

For unfamiliar planets, exploration is very necessary. In particular, Chu Fei must make sure whether he can leave after entering this planet. This is about the limit of the first cosmic speed.

The jet speed limit of conventional chemical fuels is 10 kilometers per second, which means that if the orbital speed of the planet is greater than 10 kilometers per second, the chemical fuel-driven aircraft will not be able to get rid of the planet and will be firmly bound to the surface of the planet by its own weight.

At present, the first cosmic speed of this planet is far higher than that of the earth. If chemical fuels are used, it is destined to be unable to get rid of the planet.

So facing this planet with super gravity, Chu Fei did not dare to rush in directly. If he can't get out, he will be blind.

Although Chu Fei has explored the stars of the Tenglong galaxy and even fished out hadron materials from the stars, he must always be cautious when exploring super-large planets.

Not to mention that the wind speed on the surface of this planet exceeds the standard speed of sound of 340 meters per second on Earth. It is still very dangerous.

Before entering, you must test it first. And there is also Chu Fei's clone in the aircraft.

However, the space shuttle launched by Chu Fei uses plasma engine technology for fuel, so in principle, there is no problem.

The aircraft slowly slowed down, and then was captured by the gravity of the planet, gradually falling into the dark red planet below.

The entire surface of the planet is brown-red, and it looks a bit mottled because of the floating clouds.

As a brown dwarf, its light is transmitted from the ground to the sky. For the life on this planet, their "sun" is really underground.

This is a very wonderful world. As you continue to fall, the first thing you feel is the thick atmosphere.

The main components of the atmosphere are also being tested rapidly, with 15% oxygen, 26% nitrogen, and a carbon dioxide concentration of up to 53%. The rest are rare gases, inert gases, water vapor, etc., accounting for about 6%.

If we ignore the carbon dioxide content, this planet is suitable for human habitation - we just need to modify our lungs and increase the utilization rate of oxygen.

Ordinary people may be in danger when the oxygen content is lower than 19.5%. But with training, auxiliary drugs, etc., humans can withstand a minimum oxygen content of 10% for a short period of time.

Compared with sea level, the oxygen content of the same volume of air on the Qinghai-Tibet Plateau is only 65%, which is equivalent to 14% of the oxygen content under normal circumstances, or even lower.

So 15% oxygen content can theoretically support the movement of ordinary human life.

And a large amount of oxygen means that there are plant-type organisms.

Oxygen is actually the waste gas of plants. Nature can produce a small amount of oxygen, but because oxygen is active, it will undergo oxidation reactions with substances and be continuously consumed. If you want oxygen to continue to exist on the planet, there must be plants or similar life.

The aircraft continued to fall, and when it fell to 0.7 atmospheres, which is equivalent to the air pressure position of the Qinghai-Tibet Plateau, the aircraft finally discovered life here. It was a floating plant that moved with the wind. Those "clouds" that looked like pieces from space were actually formed by this plant.

These plants are dark brown, with leaves facing the ground, which can absorb the poor light here to the maximum extent. After a simple scan, it was found that these plants grow very slowly.

But these plants also have their own way of survival. The "clouds" they condense store a lot of water, just like real clouds store water.

However, a large amount of clouds will block the light, and less clouds will cause drought. So the way plants grow is "split".

The larger the area, the more clouds gather, and the less light there is between each other. At this time, some parts of the plant will die and decay, and finally split into small "lawns".

These plants also have air sacs, but the aircraft has no conditions to test them. It is estimated that they may be hydrogen. The means by which plants produce hydrogen are actually very simple.

The aircraft continued to fall and encountered animals at a position of atmospheric pressure, that is, the "ground position". This is a bat-like creature, but its big belly looks like an air bag, and its small wings are more like the effect of a fish fin.

Then more creatures appeared, and a complete ecosystem was revealed bit by bit.

However, there is no real ground here. The aircraft continued to fall, and Chu Fei also saw flying birds, swimming fish, jellyfish (balloons) and other creatures, some of which can reach more than ten kilometers in length.

Of course, there are also creatures without air bags, which will stay on floating plants to rest. Most of these creatures without air bags are predators, with extremely fast speeds, but insufficient durability.

The aircraft continued to fall, the light gradually increased, and the ecosystem became more and more exciting.

Until it fell to a position of 7 atmospheres, Chu Fei found traces of buildings-not animal shacks, but formal buildings, or rattan-wood structures, with "balloons" hanging above the buildings.

Architecture is one of the symbols of intelligent life.

And a perfectly constructed building not only means intelligent life, but also means the emergence of civilization.

The beginning of the Yanhuang "civilization" was drilling wood to make fire (Suirenshi) and Youchaoshi. Strictly speaking, before this, it cannot be called a civilization, but only a tribe.

Seeing the traces of civilization, Chu Fei's eyes lit up, but he did not stop immediately, but drove the aerospace plane to wander in this space layer.
