"Boom, boom!"

Dozens of high-powered thrusters installed at the roots of the Immortals were at full power, pushing its massive body to accelerate, leaving a long dark blue comet tail behind it.

Several high-powered traction beams shot straight towards Proxima Centauri, exerting a huge traction force for the Immortals, and as the distance approached, the stellar gravity began to exert its power, like an invisible rope pulling the Immortals' massive body closer to them......

Although the channel chosen by Nie Yun for the Immortals was thrilling, the acceleration effect was also proportional to the risk, and with the thrusters comparable to planetary-level engines, the Immortals' acceleration would not be much slower than the Sea Clan's flagship.

In fact, the Immortals and the Sea Tribe flagships had gradually parted ways halfway through, and their passages remained roughly in tandem except for the slightly different angles at which they cut into the stars.

After all, there was no need for the Aqua Clan flagship to accept the extreme trial, and Nie Yun had no interest in testing the fire resistance performance of the Aqua Clan's spacecraft......

And the image of the immortal changed greatly at this moment, and the canopy in front of him was like a dead tree in spring, and it only took five or six hours for a large number of green leaves to finally stop growing from budding.

At this time, the huge green umbrella cover was fully formed, like a huge hat overhead, obscuring the blazing stellar light in front of it.

Each of these newly grown green leaves is the size of a washbasin, and if you look at them with a microscopic measuring instrument, you can see that they are photosynthesizing with incredible efficiency.

Moreover, the tiny dilated pores on the surface of these blades are also actively adsorbing free cosmic dust in space.

The vastness of outer space is not a complete vacuum, it is filled with all kinds of cosmic dust with huge differences in composition and density, and it is technically called interstellar matter.

The composition of interstellar matter is very complex. A large part of it is neutral hydrogen atoms, or hydrogen molecules.

In terms of density, there is an average of 1 atom in a cubic centimeter, and an ordinary Coke can contains about 330 atoms if it is placed in space.

Hydrogen is not only the main fuel for nuclear fusion, but also an important raw material for photosynthesis to produce "water", which is an indispensable element for the self-contained biological fortress of the immortals.

And the huge umbrella cover with a radius of hundreds of kilometers is like a big broom, sweeping away all the interstellar dust and particles along the way, turning them into their own nutrients and absorbing them completely!

Although the density of matter is pitiful, under the tower of gathered sand, it is still a great benefit to the material circulation in the body of the immortals, and can greatly extend the "endurance time" of the immortals.

……

Although the Immortals' body is in dire straits, inside is another world, full of vitality!

The old cells were eliminated and disintegrated, and gradually replaced by new and more powerful cells, and with the massive consumption of the water of life, the tissue functions of the immortals became more and more perfect, and they began to gradually adapt to the harsh cosmic environment.

The metabolic waste produced by the nearly two million Kara people, along with various industrial residues made by the in-house mechanized arsenal, is recycled through the powerful digestive system in the Immortals, and is turned into nutrients and raw materials for photosynthesis of the Immortals.

The oxygen produced by photosynthesis can be used to maintain the internal ecosystem in addition to satisfying the consumption of the immortals themselves.

Attached to the living space of the Kara civilization in the body of the immortals, the oxygen concentration is rising rapidly, like spring returning to the earth, and the patches of greenery are growing rapidly, and in the surprised eyes of all the Kara people, even the crops in the grain base have risen a little.

Then Nie Yun was stunned to find that if this continued development, maybe even the ecological maintenance system could be shut down, and directly relying on the immortal's own biological cycle would make this ecological space self-sufficient!

Stars are the source of life, and as the Immortals continue to get closer, the huge amount of light energy is rapidly being converted into various energy storage substances, which circulate in the body in the form of chemical energy, providing energy for the daily activities of the Immortals.

With an abundant supply of energy, the Immortals gradually got rid of their dependence on internal mechanical energy and began to evolve towards a truly complete cosmic life......

Sure enough, as the Immortal said, the harsher the environment, the more powerful the evolution effect of the Water of Life became!

Get stronger! Still getting stronger!

If I had to put words to describe how the Immortals felt at this moment, it would be ...... Addicted to the thrill of evolution!

But the pleasant evolution time is short-lived......

Proxima Centauri, a red dwarf star belonging to the main sequence stage, has only 1/8 of the mass of the Sun and 1/7 of the Sun's volume, and the hydrogen inside burns slowly and steadily, with a lifespan of tens of billions of years.

If it is compared to a pile of slow-burning charcoal, then the sun is the torch that burns violently.

Because of its stable combustion and low radiation intensity, the habitable zone of Proxima Centauri's galaxy is only 7 million kilometers away from the star.

Kara is located in the habitable zone, and the distance between Proxima Centauri is only about 6.5 million kilometers, while the distance between the Earth and the Sun is 150 million kilometers, a difference of about 20 times.

In fact, it is precisely because the star is so close to the star that the star is completely "locked" by Proxima Centauri, just as the moon is locked by the Earth, forcing the star to always "face" the star.

According to the research data inside the twin stars, it is speculated that a long, long time ago, a massive celestial body collided with the star Kara, giving it a little rotation energy, which formed the unique wonder of life on the planet today.

But the rotation of Kara is slowly disappearing in this lock, if there is no external interference, it will probably be hundreds of thousands of years later, Kara will completely stop its rotation and eventually become a death star!

On a cosmic scale, 6.5 million kilometers is not far away, so after two full days of sailing, the light of the red star has begun to gradually fill all the vision of the immortals......

The warm sunlight began to become very hot, and the leaves at the top were gradually roasted and slightly yellowed, and even the torso that was exposed to the sun began to turn black and carbonized.

Nie Yun's extreme trial has entered the most dangerous stage!

……

"Boss, are you sure this is a trial for me, not a super coke or something?" The Immortal asked with some weakness.

Although it is quite eager to evolve and become stronger, but such an exciting thing as playing a side ball on the stars sounds like it makes the tree break out in a cold sweat!

This is no longer shoulder to shoulder with the sun, but a direct veneer dance, and the scale of the play is not ordinarily large!

"What's the way, you're so big, it's so hard to accelerate, it's not extreme, and before you can join my troops, you have to be caught up and killed by the feather fleet behind.

If you have the confidence to handle the siege of more than fifty warships and countless mechs on your own, then we will now turn around and launch a heroic counter-charge! What do you think? Nie Yun said lightly.

"Uh......" The Immortals were speechless.

Completing the trial is a life of death, but if you turn around...... That's a hundred deaths!

What Nie Yun said is also true, the movement ability of the immortal naturally cannot be compared with the battleship, the two sides are now like a tortoise and rabbit race, even if the tortoise has a first-mover advantage, and the distance between the two is not short, but if the route is the same, there is still a risk of being overtaken.

Isn't this extreme trial an extreme escape?

However, although Nie Yun looked unconcerned, his movements under his hands were not slow, he not only extinguished all the energy furnaces, but also mobilized all the mechanical insects in the Immortal's body to protect several vital core areas such as the Immortal's center and the Kara people's living space.

After investing so many resources, if you can only get a piece of hunting coke in the end, it will be really useless.

The Immortals knew at this moment that this adventure could not be avoided, and they were also desperately trying to squeeze their potential, and the water of life was consumed at a speed visible to the naked eye.

As the distance approached, the Immortals faced the canopy side of the star, and the temperature began to rise.

500℃…… 1000℃…… 1500℃……

The temperature of the magma is only 700~1200 °C, and now just the stellar energy absorbed makes the immortals feel like they are eating for the first time......

It had to slowly lower the canopy above its head and close it like a giant green umbrella with its bones closed.

In this way, while reducing the area exposed to sunlight, it is also possible to protect the trunk with a shaded part that is more resistant to heat.

The distance to the stars is still shrinking, and the leaves of the Immortals finally wither and curl up in the heat, and a few of them begin to burn.

But the layers of shade were burned off, and the immortals quickly grew another layer, and the color of the newly grown leaves became darker and darker, and finally they were dark green, and the surface even faintly shone with a metallic luster!

The bark of the Immortals has become denser and tougher, and the functional organs inside have become more and more powerful, full of surging vitality, and they are still in the process of metamorphosis and evolution......

Then, under the surprised gaze of the pursuers and Isal behind him, the Immortals plunged headlong into the outermost light sphere of the star along the tangent line with an indomitable momentum!

True...... Really got into it?!

Under the intense radiation interference, the figure of the Immortals completely disappeared from their optical detection field......

Destruction breeds vitality, and the tribulations are extraordinary!

And the Immortals have undoubtedly ushered in its ...... "Tribulation" at this moment!
