The hangover after the catastrophe made everyone fall into a deep sleep, and the temporary shelter could also provide a more stable and livable environment, and the lifeship AI scanned to determine that there was no possible threat to the surface of Nirvana, including those mysterious species hiding in the caves on the surface, and there was no sign of change, so the old captain Jervis also relaxed his vigilance and sank into sleep with the rest of the crew.

Because of this, they didn't alarm anyone when they appeared.

Strange environments have created a different kind of biosphere, and the native organisms born in the strong gravitational and ray environment of the binary star are quite strange, and most of them are quite adaptable to the environment and can thrive in this harsh natural environment.

But about 50,000 years ago, after their planet was captured by a new black hole along with a binary star, the entire thriving biosphere was wiped out, and the chain reaction caused by the impact of an iron meteorite that broke into the atmosphere destroyed most of the planet, and more than ninety percent of the animals and plants were wiped out by the impact. According to the general law, the few surviving organisms will eventually become extinct due to the rupture of the food chain, and the entire planet can only evolve into higher animals and plants again after tens of thousands of years after the atmosphere is reformed and the ecological environment is slowly reconstructed.

At this time, the heavens favored these lucky ones who were still surviving, or rather, under the forging of the harsh environment of the double star, some species have been tempered with unimaginable and powerful survival ability. For three years, the surface temperature of the planet dropped to below -160 degrees Celsius due to the sand and dust raised by the meteorite hitting the earth's surface, which covered the sky for three years. The moisture and a small amount of carbon dioxide gas in the air have long since turned into snowflakes and fallen, and the whole world has turned into a silvery white.

But in such a harsh environment. Some low-hardy plants native to the poles of the planet have survived, and they have not lost their vitality due to the loss of sunlight, which originally fed on water and trace elements in the soil. On the contrary, the natural predators that used to feed on them, as well as other species in the food chain, are now all erected corpses, and the extreme cold temperatures have turned the world into a huge freezer.

The habitable environment made them extremely active, and their range began to expand rapidly, covering most of the planet in just two years, and if one looked down from above, they would see that the entire planet had turned brown (the color of moss). The unfrozen water in the soil has been absorbed by them, and there are few trace elements left in the topsoil, and the nutrients needed to expand the population have been depleted......

It is impossible to determine which moss first tried to grab the first bite of nutrients from the corpse wrapped in itself and its companions, but the key point is that its attempt was successful!!

Biologists who have studied this are generally convinced that it is the remains of other organisms frozen on the surface of the planet that help them. These "plants", which have covered the whole world, survived the long night of the last year. When the light from the twin stars finally pierced the heavy haze and sprinkled the surface of Nirvana again, rising with the melting ice and snow as the temperature rose, the heavy rain that had not been seen for three years lasted for nearly twenty days and nights, and the mosses that had struggled to support finally ushered in another spring......

Over the next tens of thousands of years, these mosses evolved so rapidly that most of the species that they had previously devoured as nutrients did not disappear completely, and mosses retained some of their DNA after the ecological environment became regular again. Mosses relied on these genetic fragments to start a new round of evolution.

There are no more natural predators, and even other species no longer exist, and for them at this moment, it has become the biggest problem!!

The word "circle" in the word biosphere can be said to be the core of all life to thrive. The process of development and strength of any species is closely related to other species in its environment, and the entire biosphere is in fact a symbiosis that competes with each other and depends on each other. The so-called big fish eat small fish, small fish eat shrimp, shrimp eat mud, and the top big fish in the whole chain finally dies. It turned into the mud that the shrimp eat. Of course, this example is only a simplified analysis, and the relationship between all species in a truly mature biosphere is infinitely more complex than this. But the general principle is indeed the same.

In the earliest stage of imperial colonization, how to make a suitable planet habitable and provide the necessary conditions for the survival and development of immigrants on the premise of maintaining the original ecological environment is the part that all colonial fleet managers think about the most and spend the most energy.

This problem that plagues all human colonists is also the number one enemy of these mosses on Nirvana, and they may now be finally destroyed by their own strength after surviving the long winter!!

Biologists have since determined that in the face of this major existential crisis, they have once again begun an incredible evolutionary process. The first to change are the mosses that have devoured predators, using the few remaining genetic fragments of their devoured subjects to develop skills unique to predatory species, predatory and devouring.

The rest of the mosses that have devoured different species have also mutated with their genetic fragments to develop their own new skills...... About 5,000 years before the landing of the Saint-Brandt lifeship, Nirvana's biosphere had become complete and vibrant again, and if nothing else, it might even give rise to intelligent life.

Once again, bad luck has dealt a blow to the planet and its people.

Its orbiting binary star system has been orbiting the nascent black hole that captured them for tens of thousands of years, and the entire orbit has moved much closer to the central region of the black hole over such a long time. The closer you get to the center, the more chaotic the environment becomes, and more and more meteors and meteorites of all sizes break into the gravitational sphere, and the stability of the binary star system begins to be constantly disturbed.

Naturally, the changes in the binary star system will also affect the only planet in the entire galaxy, and the natural environment of Nirvana has once again become quite bad, and the newly reformed biosphere is once again facing collapse, and more and more animals and plants are beginning to become extinct. But this is not the inevitable end of all species, the tenacious will and ability to survive hidden in some animals and plants, stemming from their moss ancestors, are beginning to awaken, and they begin to subconsciously (and possibly actively) change their way of life......

On the night of the crew's hangover, a group of predators hiding underground smelled the scent of their prey, and after making sure that the prey had fallen asleep, they quietly crawled out of their stealth nest and began to move...... (To be continued.) )

ps: There is a class tonight, hurry up and pass this chapter to the end, thank you for your great reward, and thank you for continuing to pay attention, the old man is continuing to cheer!!
