In a small canyon around the highlands, there is a cave with a diameter of about 45 meters on the cliff. This was once one of the corridors for volcanic magma flowing, but for more than 2 billion years, no magma has flowed from here.

This planet is not a forbidden zone for life as humans know it. The extremely harsh environment and atmospheric structure on the surface of the planet are indeed a forbidden zone for life, but this is limited to the surface.

When the volcanoes filled with Mars gradually died, the magma retreated, and the corridors inside the volcano became the last safe haven for life on this planet.

A creature with a history of more than 2 billion years still exists on this planet and is also the only large creature remaining on this planet.

In the cave passage where the small canyon is located, it is moving at a speed that is neither fast nor slow. In the eyes of humans, it is actually moving very slowly. It is also a failed competitor. In another similar male, he failed in the competition for mating rights, and was lucky enough to escape the opponent's bloody mouth. Now it has become an ascetic, who has escaped from the nest deep underground. Its body is covered with scars, has not healed, and its body is becoming weaker and weaker.

After leaving the water, for the oxygen needed by the body, it begins to consume its own water to produce the oxygen needed. This is undoubtedly a chronic suicide, but it is also the best way at present.

It is already a miracle to be here alive, because the failure of the creatures in this population from the competition for mating rights often means becoming a big meal for the winners, especially in the environment of evil, where no grass grows, which is the rarest delicious meal.

For this only species on Mars, this is not only a competition for mating rights, but also a competition between life and death. The winner will complete mating with the female and obtain everything about the loser, including its body, while the loser has nothing and even becomes the food for the winner. This is the cruelest competition.

It is already a miracle that it can escape.

At this moment, it crawled to a steep slope, and the other end behind the top was a steep slope with an inclination of up to 60 degrees downward. Such a steep slope was not a big deal for this kind of creature, but it was an exception. It was too severely injured and its breath became weaker and weaker. What was waiting for it was more of the arrival of the god of death. It could not safely pass through this steep cave inclined passage.

But it must move forward. When it crosses the apex of the cave, its entire body will finally slip like a rolling stone in the steep cave. Its body can be curled into a sphere to protect itself and roll down in the cave wildly.

The Pezos Heights, outside the canyon, and at the entrance 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 die without death

It suddenly made a heart-wrenching and tragic scream. However, the thin atmosphere on the surface of Mars, the length of the sound spreading is only 15 of that on Earth.

The thin atmosphere on the surface of Mars has almost no oxygen. This species can adapt and survive. It has lasted for billions of years in this world known as a forbidden zone of life. This species lives deep in the ground for billions of years, and there is something that is a deadly cosmic ray for it.

The Pezos region is about to enter the darkness, but at dusk, the sun still shines on this land. Ultraviolet rays and various cosmic rays from outer space can still make it die without a burial place. The instinct of survival makes it struggle wildly and quickly escape from this place, which is completely opposite to the dying moment before, but it does not know that there is nowhere to escape on the empty surface.

Its epidermis began to burn, and the speed visible to the naked eye began to ulcerate, and the muscle tissue began to turn into pus, leaving it on the path it crawled. The pus suddenly hit the soil layer on the ground, and the trace amount of water contained in the soil began to dehydrate severely. The thin air was filled with a strong acidic corrosion smell.

Finally, it was exhausted. It escaped from the competition of its rivals, but it could not escape the final life-seeking of Death. It rolled down from the cave on the cliff to the surface of Mars. It climbed 80 meters long and finally stopped. The pus was immersed in the surface soil layer, and finally only a pile of complete skeletons left on the ground, and the white smoke spread around it and quickly dissipated.

Following the cave entrance on the cliff to penetrate into the bottom of the extinct volcano. When entering the cave from the exit, you must first climb over a steep slope. The creature lost his life because of this steep slope. Then it went deeper into the ground. As it continued to deepen, it began to appear crisscrossing cave networks.

As we continue to deepen, every inch deeper you get closer to the core of Mars, a new cradle of life appears underground. The core of Mars is around 1,700 degrees Celsius, and the temperature is always maintained here. In the ancient times of Mars, when volcanic activity was the most intense and frequent, this place was magma, but now it is composed of water. It maintains a perfect distance from the core of Mars, which has a high temperature of 1,700 degrees Celsius, just like the right habitable zone distance between the earth and the sun in the solar system, which prompts the water on the earth to liquefy.

There is a similar "livable zone" underground on Mars, where water is liquid. In addition to this golden geographical location, the soil on the surface of Mars also has water components. If humans know all this, it may be able to explain the mystery of the source of water contained in the soil layer.

The golden geographical location allows water to liquidize here, and the underground space originally formed by volcanic magma or the crisscrossed corridor also gives the possibility of water convergence.

This is the last habitat of life.

Deep underground in the Pezos region, there is a huge reservoir here, but it is definitely not the only one on this planet. This reservoir is no less than Dongting Lake. Swarms of reptile creatures gather at a shore port, and the size of these creatures is more than three times that of adult Komodo dragons on Earth. They are reptile creatures, with a single body having more than 3,500 muscle tissue, while humans have only more than 600 pieces.

This type of creature does not have moving limbs, but crawls like snakes. There is a pair of forelimbs that are basically not used for movement. They are more used for combat. They are composed of three ligament joints and can be straightened but usually semi-contracted into a "" shape, just like the forelimbs of mantis on Earth.

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

At this moment, the creatures at the shore port intertwined each other, and the body surfaces of these creatures flashed from time to time. The huge current generated here could kill an adult instantly, but it did not hurt at all for these creatures.

Because these currents are generated from these organisms.

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

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

But they can create the oxygen needed for life activities by themselves, and trace amounts of oxygen in the air also come from them.

The reason why this type of organism can generate powerful currents and acidic solutions independently is that a unique type of organ has evolved. This type of organism in the body creates oxygen for life through the process of "electrolysis of water". The acidic solutions secreted by this type of organism also serve this. They can increase the concentration of ions in the water, thereby enhancing conductivity, and thus speeding up the reaction rate to support the oxygen needed by the body.

The evolution of billions of years has allowed this species to survive in a harsh environment. However, the energy consumption required for such a huge volume is definitely not to be lingering in groups. If they have the chance, they will eat their similar species without hesitation and swallow a similar species intact that can satisfy long-term activities. The harsh living environment makes them cruel to survive, but this alone cannot continue to this day. Eating similar species will eat nothing left one day.

This type of last remaining Martian creatures means that they have no source of food, and the thin oxygen on Mars can be almost neglected, making it even less likely to provide such a huge organism for respiration. Their huge bodies require a lot of oxygen to maintain their life activities. They create oxygen by secreting strong acid corrosion and electrolyzing water, but secreting acid corrosion and providing electricity means consuming more body functions. Without food as a supplementary source of body energy, it is impossible to survive.

But even in such a harsh environment, they still have their own unique survival skills, which is unheard of by humans
