In a small canyon around the highlands, there is a karst cave with a diameter of about 4.5 meters on the cliff face, which was once one of the channels for volcanic magma flow, but no magma has flowed from here for more than 2 billion years. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

This planet is not a forbidden area for life, as humans believe. The extremely harsh environment and atmospheric structure of the planet's surface are indeed off-limits to life, but this is limited to the surface.

When the volcanoes that Mars is full of are gradually dying, the magma is receding, and the corridors inside the volcano become the last safe haven for life on this planet.

A creature more than 2 billion years old still lives on this planet, and it is the only large creature left on this planet.

In the cave passage where the small canyon is located, it is moving at a slow pace, which in the eyes of humans is actually very slow, and it is also a losing competitor, losing the competition for mating rights among another male of the same type, and luckily escaping the blood of its opponent. Now it has become an ascetic, and he has escaped from its lair deep underground, and it is covered in scars that have not healed, and its body is getting weaker and weaker.

After leaving the water, it begins to consume its own water to produce the oxygen it needs for the oxygen it needs, which is undoubtedly a chronic suicide, but it is also the best way to do it.

It's a miracle to be alive, because the creatures in this population, losing the competition for mating rights, often mean a winner's meal, especially in a bad environment, where Mars does not grow a single crop, which is the most rare meal.

For this only remaining species on Mars, this is not only a contest of mating rights, but also a contest of life and death, the winner will complete mating with the female and get everything from the loser, including its body, and the loser will have nothing, even the flesh will become the food of the winner, this is the most cruel competition.

It's a miracle that it can escape.

At this moment, it crawled to a steep slope, and at the other end of the top was a steep slope of up to 60 degrees, such a steep slope was not a big problem for this kind of creature, but it was an exception, it was too badly injured, its breath was getting weaker and weaker, and what awaited it was more of a death coming, and it could not pass through this steep cave slope safely.

But it had to move forward, and when it crossed the apex of the cave, it finally slipped like a rolling stone in the steep cavern, and its body could curl up into a sphere to protect itself, and it rolled down the cave frantically.

The Pezos Heights, outside the canyon, at the mouth of the cave, it rolled out from the inside, fell outside the canyon, and was also exposed to the surface of Mars.

Exposed to the sun, it will be dead and lifeless......

It let out a heart-rending scream. However, the thin atmosphere on the surface of Mars has only 1.5% of the length of sound propagation on Earth.

The thin atmosphere on the surface of Mars, with almost no oxygen, has been able to adapt and survive for hundreds of millions of years in a world known as the forbidden zone for life, this species has lived deep underground for hundreds of millions of years, and there is one thing that is extremely deadly to it - cosmic rays.

The Pezos region is about to enter the night, but at dusk, the sun is still shining on this land, the ultraviolet rays and various cosmic rays from outer space can still make it die without a place to be buried, and the survival instinct makes it struggle frantically, quickly trying to escape from this place, the opposite of the previous dying, but it does not know that there is nowhere to escape from the empty surface.

Its epidermis began to burn, the visible speed began to fester, suppurated, muscle tissue began to turn into pus, left in the path it crawled on, pus touched the soil layer on the ground and suddenly white smoke appeared, the trace amount of water contained in the soil began to be seriously dehydrated, and the thin air was filled with a strong smell of acidic corrosion......

Finally, exhausted, it escaped from the competition of its rivals, but it could not escape the final call of death, rolling down from the cave on the cliff wall to the surface of Mars, it climbed 80 meters long, and finally stopped, pus soaked into the surface soil, and finally left only a complete pile of skeletons on the ground, white smoke filled around it and quickly dissipated.

Following the mouth of the cliff wall deep into the base of this extinct volcano, the cave enters through the exit by climbing over a steep slope where the creature lost its life, and then all the way to the ground, and as it goes deeper, a network of karst caves begins to appear.

As we go deeper, every inch closer to the core of Mars, a new cradle of life appears underground, the core of Mars is about 1700 degrees Celsius, and here it has always maintained a stable temperature, in the ancient times of Mars, when volcanic activity was most intense and frequent, here is magma, but now it is made of water. The distance from the core of Mars, which is 1,700 degrees Celsius, is just as close as the habitable zone between the Earth and the Sun in the solar system allows the water on Earth to liquefy.

There is a similar "habitable zone" underneath Mars, where water is liquid. In addition to this prime location, the soil on the surface of Mars also has a water component, and if humans knew all this, it might explain the mystery of the source of the water contained in the soil.

The golden location allows water to liquefy here, and the underground space or the interwoven corridors formed by volcanic magma also make it possible for water to converge.

This is the last habitat of life.

Deep underground, in the Pezos region, there is a huge reservoir, but it is definitely not the only one on the planet, this reservoir is no less than Dongting Lake. Groups of reptiles, more than three times the size of the Earth's adult Komodo dragons, are reptiles with more than 3,500 musculature in a single individual, compared to more than 600 for humans.

Instead of moving limbs, these creatures crawl like snakes, and have a pair of forelimbs that are basically not used for movement and are more used for fighting, consisting of three ligamentous joints that can be straightened but are usually semi-constricted into an "S" shape, like the forelimbs of a praying mantis on Earth.

What is unbelievable is that the air here contains a higher oxygen content than the surface atmosphere of Mars, although this tiny oxygen content is impossible for humans to breathe, but if it is discovered by humans, it will definitely be a sensation in the world.

At this moment, these creatures on the shore mouth are intertwined with each other, and from time to time the surface of these creatures flashes a dazzling electric current, and the huge electricity generated here can kill an adult instantly, but it is not the slightest harm to these creatures.

Because these currents are generated from these organisms.

The water here is also the deadliest venom for humans, because the water is full of strong acidic corrosion, and the strong acidic substances in the water also come from these remaining Martian creatures.

Mars does not have plants, but these creatures also need to respire, and oxygen is essential, but there is not enough oxygen on this planet for them.

However, they are able to produce their own oxygen for life, and trace amounts of oxygen in the air are also derived from them.

The reason why these organisms are able to generate powerful electric currents and acidic solutions on their own is because they have evolved a unique class of organs, which produce oxygen for life through the process of "electrolysis of water", and the acidic solutions secreted by these organisms are also in the service of this, which can increase the concentration of ions in the water, thereby enhancing the conductivity, and thus accelerating the reaction rate to support the oxygen required by the body.

Hundreds of millions of years of evolution have allowed this species to survive in the harsh environment, but the energy consumption required for such a huge volume is definitely not small, don't look at their current swarms of "lingering" together, if there is a chance, they will not hesitate to eat their kind, completely swallowing a kind of species can meet the long-term activity, the harsh living environment has created them must be cruel to survive, but only this can not make them continue to this day, eat the same kind will one day eat a left.

The last remaining Martian creatures, this means that they have no source of food, the thin oxygen on Mars is almost negligible, and it is impossible to supply such a large creature for respiration, and their huge bodies need to consume a lot of oxygen to maintain life activities, they produce oxygen by secreting strong acidic corrosion and electrolysis of water, but secreting acidic corrosion and providing electrical energy means consuming more bodily functions, and it is impossible to survive without food as a source of energy for the body.

But even in such a hostile environment, they still possess their own unique set of survival skills that humans have never heard of......
