……

The rover continued on its way, came to a stop at a ramp, and continued on its way with a strobe instrument placed on the sidewall. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Ma'am, you help watch first, I'll go get something to eat." Ren Hong said that he had been sitting here for most of the day.

Just as he walked to the door, Aisling suddenly subconsciously exclaimed, "God......"

Ren Hong instinctively stopped, turned around and looked back at the console, Ai Sling looked at the screen with a shocked face, completely unaware that "Wang Jiang" was looking at her.

"What's wrong?" Ren Hong asked suspiciously.

"I suggest you wait a while before eating, it's best to come and see, it's incredible......," Aisling said as if talking to herself, still staring at the screen.

Seeing her expression, Ren Hong didn't want to come back directly, and glanced at the information displayed on the screen, he was also stunned.

For the first time, the rover came to an open area, or a larger and wider tunnel, and a grid-like three-dimensional topographic map showed bulging balls, at least 30 of them, all over 2.7 meters in diameter.

"Fermentation?" Ren Hong said subconsciously, at this moment he had forgotten that his stomach was growling, and those bulging hemispheres were all fermented products.

He made a few quick taps on the keyboard, and in a few moments, the three-dimensional image was replaced with a thermal image, and then with another graphics mode.

Deep underground, a new camera immediately appeared on the top of the Mars rover, and two thin fan-shaped green laser barriers were lined up horizontally and erected, which were extremely dazzling in the dark depths of the earth, one laser barrier from top to bottom, and the other side scanned back and forth against the terrain in front of it from left to right.

Yang Licheng, who was standing on the sidelines and was silent, was also moved when he saw the next scene, and the hand that was wrapped around his chest was also put down, and he looked at the screen with his eyes wide open.

The screen information data shows more than 30 strong life signals, living life signals, the signal source is the more than 30 motionless giant spheroids, through the data feedback of the biological scanner, the internal structure of the giant spherical fermentation products is displayed.

Inside each orb is a huge body curled up like a snake, it is none other than the Martian snake lizard!

"It's ...... Snake lizard eggs? Aisling looked at the screen and turned her head to look at Ren Hong.

"No, if you look at its size, although it is curled, it is at least more than three and a half meters wide, and it is obviously an adult individual. The spheres that envelop them are unknown yeast organisms......" Ren Hong looked at the data displayed on the other screen: "Moisture content 30%? ”

"Facultative anaerobic?" Ren Hong was suddenly shocked and said: "I know, no wonder they haven't shown signs of activity in the past six months, it turns out that they are in the dormant period or hibernation period, see?" They're sleeping, they're sleeping! ”

"The environment of Mars is harsh, food is extremely scarce, if you stay active throughout the year means that you need to eat constantly in order to maintain the calories consumed by life activities, but hibernation is different, the purpose of eating a big meal and sleeping for a long time is to reduce physical energy consumption, and the dormant period becomes facultative anaerobic ......" Ren Hong looked at the screen in amazement: "This is the most energy-cherishing creature I have ever seen, almost saving energy consumption to the extreme...... Facultative anaerobic, no wonder there will be a fermented mushroom wrapped into a sphere, snake lizards will even ferment to produce fermented fermented mushrooms, dormant period plus facultative anaerobic characteristics, this process not only consumes almost no energy, but also during the long dormancy, the facultative anaerobic state of the body surface for fermentation, this mass of huge fermentation that has been completed for a long time is simply a super meal for Mars, which is starved of food. ”

"But even that won't complete a cycle of life, and don't forget that they're on the surface of Mars." Aisling questioned.

"Still don't understand?" Ren Hong pointed to the data display, "The change in humidity, anaerobic and facultative anaerobic microorganisms in the soil that do not rely on oxygen to live, simple and low-level life has appeared here, do you see the temperature change?" The deeper you go underground, the temperature is rising, now it is minus 30 degrees Celsius, and the lowest temperature in the upper layer is above minus 47 degrees. And what about ...... further down?"

"Where is this? Under our feet. Ren Hong asked rhetorically.

"Volcano! And it's an extinct volcano that has been dead for hundreds of millions of years. Aisling replied.

"What's under the volcano?" Ren Hong asked again.

"What do you mean......" Ai Ling's eyes lit up, Ren Hong snapped his fingers, and then said: "The source of life, water!" Liquid water! The Martian core temperature exceeded 1,500 degrees Celsius. ”

Ren Hong suddenly stretched out his fist and said figuratively: "Mars is a star system, the core furnace of more than 1,000 degrees Celsius inside is the scorching sun, and the different stratigraphic structures represent planets and planetary orbits...... Ren Hong gestured, looked at his fist with a smile and said: "There is a golden location, where the temperature is just enough to make the water appear liquid, habitable zone!" Just like the sun and the earth, the earth is in the prime location, the habitable zone! Water can be liquefied on the earth, and liquid water ...... The source of life, the habitable zone under Mars, also exists! ”

"This would explain why the soil on the surface of Mars contains water." Ren Hong said with great affirmation: "Because there is liquid water under Mars, in the form of groundwater, water is stored in the hollow extinct volcano, water usurps the 'home' of hot lava and becomes the new flowing 'blood' of the volcano, and the extinct volcano is therefore 'reborn', and the underground of Mars is a new life world, and the snake lizard may be the master of that world......"

Still untenable, Esslyn questioned, "Water is indeed the source of life, but what about oxygen?" Could it be that there will be plants underneath Mars? There is no complete food chain, no complete biological ecology, no balanced ......"

"The existence of snake lizards is not true." Ren Hong interrupted her, and Ai Sling was speechless.

"Let's make a hypothetical ...... together" Ren Hong said to himself: "Hundreds of millions of years ago, Mars was a prosperous planet of life, biological extinction broke out, snake lizard is one of the survivors, many species are extinct because of the great changes in the environment, snake lizards escaped, the great changes in the environment, the collapse of the food chain forced them to continue to evolve and avoid extinction, the dead volcano became their new settlement, the extinction of Martian plants led to the disappearance of oxygen, what if there are no plants to provide oxygen?" They make their own oxygen ......"

"Animals? Homemade oxygen? Aisleen looked at him suspiciously.

"Any organ or behavior that a creature has evolved is to adapt to survival, otherwise it is a burden that consumes energy in vain, why can snakes and lizards secrete acid corrosion? Why are snake lizards able to generate electricity? Ren Hong asked rhetorically.

Seeing that the blonde girl still didn't know what to do, Ren Hong said succinctly: "They use these two skills to produce oxygen in the form of electrolyzed water!" ”

In one sentence, Aisling at this moment suddenly became enlightened, there are too many ways to survive oxygen, and the photosynthesis of plants is only the most common, among which electrolysis of water is also the most conventional way to produce oxygen.

This would explain why snakes and lizards generate electric currents and secrete acidic corrosives. The environment of Mars is harsh, food is scarce, and the evolution of any organ part will inevitably degenerate if it has no effect, and these two unique skills happen to be large energy consumers, so what is the use of evolving if they have no effect?

"Incredible...... Esslyn said to herself in amazement.

"Explorer! Biological samples are taken immediately and returned to the surface. Hopefully it won't wake up these hibernators......"

When Yang Licheng heard this, he immediately said on the communicator: "Attention all units, stay vigilant, and prepare for battle!" (To be continued.) )
