Chapter 523

This kind of creature will be in the "habitable zone" of Mars for a period of time. When the periodic mating and activity carnival is over, the male and female will be in different places. The male will leave the "livable zone" and move upward along the cave, while the female will stay in the "livable zone" forever.

Although the only remaining Martian creatures are cruel and ferocious, they will not hesitate to eat the same species so that they can get more advantageous living space, but they also emit the most praiseworthy and beautiful maternal glory of life.

In order to mate, the liquid water of Mars "livable zone" has little oxygen, but it is still anaerobic water. It is in the volcano, and the water contains a lot of silicate and other substances. However, these are not the biggest threat to small life. The real threat is the oxygen resistant anaerobic microorganisms in the water.

But their mothers have a way. Their mothers secrete acidic corrosive solutions that are lethal to other creatures. This liquid can not only accelerate the reaction rate of oxygen production, but also become the patron saint of the birth of small life.

In the first four months of new life's growth, they have no resistance. Any external factors can make them die. This is the ultimate sacrifice of mother. In order to grow healthily, new life must not leave the nest, release acidic corrosive solution regularly to provide protection for small life. Being unable to leave the nest means that the mother can not get food source, but also must To secrete acid corrosion solution to protect eggs. Therefore, it is no surprise that the mother's body is becoming weaker and weaker, and the secretion of acid corrosion is also less and less. Fortunately, with the passage of time, the small life is growing vigorously, and the resistance to the outside is increasing.

In this process, the mother will die of starvation due to lack of food and hibernation to reduce the consumption of body functions. However, its mission is not over, and there is one last dedication.

When the baby hatches, the mother's body is the only source of food for the baby, otherwise the fragile young life will not survive. Large female corpses will not be decomposed in a short period of time, and there are no microorganisms. Acid corrosion plays the best preservation function here. The female corpse can provide 20 or 30 new life for nearly 60 Earth days and complete the initial growth.

The new life has completed the initial growth, and has enough ability to leave the hotbed of deep water and come to the mouth of the water surface, where there are a large number of male corpses. The former losers, the anaerobic environment and the acid corrosion that once secreted protect the corpses from being eaten by microorganisms. New life gets a second source of food on the shore, and can complete the second growth and development with the help of the last "heritage" of the ancestors.

Three months later, the corpses on the shore were almost consumed by them, and the original new life had grown up. The sudden decrease of food made them feel hungry for the first time. They were used to eating the corpses of the same kind, so they focused on the living ones, even the brothers and sisters. They saw the moving ones as if they saw the delicious food in the world Yes, we will put it into practice.

Therefore, after they come to this world, they will fight for the first time in their lives. In order to survive, during this period, some of the weak are eliminated and become the delicious food of the strong. All the strong survive. No one can kill anyone. After a long time of fighting, both sides will lose.

But their survival will continue. In order to avoid dying of starvation in the future, they have to find new ways to survive. One by one, they left the "livable zone" one by one, followed the path of their ancestors and left for the colder area above.

Looking for a safe and undisturbed place, they curl their bodies into a sphere, and with the help of acidic corrosive solutions, they erode a groove in the rock wall or other places to prevent them from falling during dormancy. So the long dormancy begins, and the rate of metabolism is getting lower and lower. They are gradually transformed into oxygen resistant anaerobes, which means that they no longer need to consume huge amounts of energy to produce the oxygen they need for their bodies, during which time they no longer use oxygen as their ultimate electron acceptor.

As time went on, the surface of their bodies began to ferment and eventually wrapped up the whole body. The next time they wake up, they will eat all the fermented materials from inside to outside to get energy supplement. After replenishing the hungry body, they can return to the "livable zone". When they reach the "livable zone", they will have a greater advantage to defeat their competitors, obtain the mating right and everything of the loser, and become the biggest winner in life.

So again and again, this species has been on Mars for hundreds of millions of years. After the great changes of the planet, one species went extinct. Only this species has survived and become the last survivor, migrating from the surface of Mars to the bottom of Mars.
