Beneath Deep Space

Chapter 261 Geothermal Organisms

"Lizardmen, these are real lizardmen! They also hold spears! They are exactly the same as the ones in the movie, except they are a little smaller..." Zhang Peng said excitedly.

"What lizard...what's all the fuss about?"

"Hei" didn't want to talk to him at first, but when he saw that Zhang Peng was really noisy, he had to say angrily: "What an ignorant country bumpkin? Isn't he a geothermal creature?"

Zhang Peng immediately pricked up his ears and listened. Actually...

He's just here to make excuses!

It has been a long, long time since he submitted a useful "diplomatic report."

"What are geothermal creatures?" Zhang Peng asked pretending to be curious.

Over the years, he has gradually understood the strange psychology of "blackness".

It seems that he was stimulated by many online novels. This idiot wants to show off all day long...

Yes, it seems that "pretending" can bring it great pleasure.

Zhang Peng secretly slandered that this kind of alien is indeed not a normal creature. Wouldn't it be embarrassing to act cool all day long?

"Black" didn't know Zhang Peng's psychological activities, and felt that Zhang Peng's question was not a big secret, so he said directly: "The evolution and reproduction of life require a stable source of energy. All life activities require Energy. Isn’t that hard to understand?”

"The most common source of energy is, of course, stellar illumination. This kind of life is called illumination-type life, and it is the most common in the universe."

Of course, talking about these things that humans don't know also means showing off their knowledge.

Whenever he sees Zhang Peng's dumbfounded expression, he always feels a great sense of accomplishment for "pretending to be awesome".

Well, this weird emotion only comes after having a human body...

It was impossible for it to be so mentally retarded before.

However, it is unwilling to say too much and save money on this low-level civilization, so it is always very conflicted in its heart.

Sure enough, Zhang Peng showed an expression of "humbly asking for advice", which greatly satisfied Hei.

It had no choice but to speak reluctantly: "The second category is, of course, geothermal-type creatures."

"The essence of geothermal energy is the nuclear fission of radioactive elements. Generally speaking, it can last for hundreds of millions or even billions of years, so it can also become a stable source of energy."

Zhang Peng nodded seriously. The earth's 4.6 billion-year lifespan still has a huge amount of geothermal energy, not to mention the Nix star, which is larger and has more geological activities.

Uranium-238 has a half-life of 4.45 billion years. In other words, geothermal energy will be reduced by half every 4.45 billion years. This time span is really too long.

So geothermal energy is actually a very stable energy source that can be output as steadily as a star.

Zhang Peng quickly wrote down these things in his notebook, and then kept asking: "According to this, there is no star illumination on the surface of Nix. If there is life, it can only be geothermal energy life, right? ?”

"...The Mars virus in the Mars uranium mining area actually uses nuclear fission energy, and should also be classified as geothermal energy life. So, are there other life forms? Are there only these two?"

This is a question he sincerely asked. If humans encounter strange life forms in the future, they will be prepared... and will not always exchange their lives for knowledge!

Zhang Peng actually blamed himself for the landslide this time and felt that he also had some responsibility. He knew that the "black" in his mind would definitely have relevant login knowledge and safety precautions.

Unfortunately, this "black" seems very unwilling to serve humanity.

Only after people discover an unknown thing, it will temporarily add a few words to show its erudition, and other times it will be almost silent.

Zhang Peng couldn't do anything with it either.

But this time, "Black" did not act coy. It was silent for a long time and said: "The light type and the geothermal type are the two common life modes of carbonyl organisms. They are also the two most likely to form large organisms and intelligent civilizations. Energy methods, because their energy sources are the most stable and reliable!”

"However, life is everywhere in the universe, and you may have realized this. The tenacity and universality of life are indescribable in words..."

"Not only carbonyl-based organisms, but also silicon-based organisms and sulfur-based organisms, but they are not common. There are even... advanced life forms based on photons and energy as units, forming a more advanced civilization. It is really Species we can hardly imagine.”

"But most life forms are relatively low-level and understandable."

"We once visited an almost dead planet. There was no light, no geothermal heat, and even no uranium mines! Energy was extremely scarce, and there was only a group of tenacious microorganisms that could decompose organic matter such as methane..."

"Is there anything strange about decomposing methane?" Zhang Peng couldn't help but ask.

He was actually more curious about the advanced life forms of the photon type, but when he saw that Hei Ming was vague and didn't want to say anything, he could only suppress his curiosity.

"Yes, there is nothing unusual about a creature that can directly utilize chemical energy."

Hei said calmly in his mind: "But we were surprised to find that after hundreds of millions of years of survival and reproduction, all the chemical energy on this planet has been exhausted, leaving no trace. But they still exist Wait, don’t you think it’s strange?”

"Why? Don't they need energy? Do they survive by devouring each other?" Zhang Peng asked curiously.

Seeing Zhang Peng's curiosity, "Black" felt like he had succeeded in pretending to be cool.

It laughed and said, "How long can we eat each other? Just like you humans, if you lose all food, can you survive for millions or tens of millions of years by eating each other?"

"...No."

Zhang Peng was extremely disgusted with the example given by "Black" and got goose bumps all over his body.

"So, the real answer is... meteorites! When these microorganisms lack energy, they will automatically lose all water and enter a dormant state like wood fiber. Only when the meteorite hits the ground and brings a small amount of energy, will they become active again, survive and reproduce..."

"All the life on a planet, they have exhausted all the energy in the planet, all waiting for the impact of the meteorite... The impact of the meteorite is their entire source of energy!"

"You can imagine how sad these lives are. Is this way of survival lucky or another kind of misfortune?" "Black" said meaningfully.

"But they are just microorganisms..." Zhang Peng said halfway, as if he understood something, and stopped talking in silence...

The caves under the ground are getting wider and wider, and the temperature is getting higher and higher.

"This is the big cave where the village is located. We are almost there!" A soldier shouted loudly, and his voice became excited.

This central cave near the crater is really huge. The lava mouth alone is ten kilometers wide! In the bottomless place below, you can even see thick red lava!

And the whole area is like a high-rise building, divided into dozens of upper, middle and lower floors, with convenient transportation.

It looks like... an underground city dug by dwarves in mythology!

All creatures in the underground ecosystem live on this pile of lava.

All underground creatures are not afraid of the poisonous gases of the volcano. These high-concentration carbon monoxide and hydrogen sulfide gases that can easily poison people are actually excellent supplements for them...

People's destination-the indigenous village happens to be located on one of the volcanic rock walls, occupying less than one ten-thousandth of the entire cave.

There are large and small earth mounds and caves on this volcanic rock wall, which should be the residence of lizards.

The village is surrounded by a circle of wooden fences and thick earth walls, leaving only a small entrance.

Many lizards lay on the walls and at the entrance of the village, looking at humans curiously.

"It seems... they have learned to build villages and invented the method of piling up earth walls, which is equivalent to our Stone Age!"

A sociologist studied these rough walls with great interest.

He just wanted to walk over and touch the wall, but the lizards above screamed in panic.
