“Lizard man, this is a real lizard man!”They have spears!It’s almost the same as in the movie, but it’s a little bit smaller...” Zhang Peng said excitedly.

“What lizard...what’s the fuss?”

"Black" did not want to take care of him, saw Zhang Peng noisy really strong, had to say not good mood: "Isn't it an unknown countryman, is it not a geothermal creature?"

He raised his ears and listened, in fact.

He came to talk!

He has not submitted a somewhat useful “diplomatic report” for a long time.

“What is a geothermal creature?”Zhang Peng pretended to ask curiously.

Over the years, he has gradually figured out the strange psychology of "black".

It seems to have been stimulated by many online novels, and this fool thinks of pretending all day long...

Yes, it seems that "presupidity" can bring him great pleasure.

Zhang Peng secretly slandered, this kind of alien is really not a normal creature, all day long pretending to be embarrassed and panicked?

"Black" does not know Zhang Peng's psychological activities, feel that Zhang Peng's problem does not seem to be too big a secret, it directly said: "The evolution of life reproduction, must be a stable source of energy, all life activities need energy."It’s not hard to understand, is it?”

“And the most common source of energy, of course, is the illumination of stars, and this life is called a light-like creature, which is the most common in the universe.”

Of course, to say that these things that human beings do not know, it also has a meaning to show off their knowledge.

Whenever I see Zhang Peng's dumb expression, it will always have a huge sense of accomplishment that is "pretentious".

Well, this strange emotion is only after having a human body...

It couldn’t have been so mentally retarded before.

However, it is not willing to say too much, the low-level civilization that is cheap and cheap, so the heart is always very contradictory.

Sure enough, Zhang Peng made a "humbly ask for advice" expression, so that black is very satisfied.

It is difficult to say: "The second category, of course, is geothermal organisms."

“The essence of geothermal is the nuclear fission of radioactive elements, which can usually last for hundreds of millions or even billions of years, so it can also be a stable source of energy.”

Zhang Peng nodded seriously, the earth's 4.6 billion years of life still has a huge number of geothermal, not to mention this larger, more geological activity of the Knicks star.

The half-life of uranium-238 is 4.45 billion years.That is to say, every 4.45 billion years, geothermal heat will be cut in half.This time span is too long.

So geothermal is a very stable energy source, and it can be exported as steadily as a star.

Zhang Peng quickly wrote down these things on the book, and then kept asking: "As you say, there is no star light on the surface of the Knicks star, if you have life, in fact, it can only be geothermal energy life, is it?"

"... the Martian virus in the uranium mine of Mars, which actually uses nuclear fission energy, should also be divided into geothermal energy life."Are there other life forms?Is it just these two?”

This is his sincere question, if human beings encounter strange life later, they will be prepared... not always at the cost of life in exchange for knowledge!

This time the landslide accident, in fact, Zhang Peng is quite self-blame, feel that he also has a part of his responsibility.He knew that the "black" in his mind would certainly have relevant landing knowledge as well as safety attention points.

Unfortunately, this "black" seems very reluctant to serve mankind.

It is only when one finds an unknown that it adds a few words to show its eruditeness, while the rest of the time is almost silent.

Zhang Peng also took it without a rut.

However, this time, "black" did not twist and pinch, and it was silent for a long time: "Light type and geothermal type are two common modes of life in carbonyl-based organisms."It is also the two most convenient ways to form large-scale organisms and intelligent civilizations, because their energy sources are the most stable and reliable!”

“But life is everywhere in the universe, and you may have already realized that.The tenacity and universality of life are indescribable in words.

“Not just for the cathodenics, but also for silicon-based organisms, and for sulphur-based organisms, but they are not common.There are even higher life forms in photons and energies that make up a higher civilization, a species that we can imagine.”

“But most life forms are less understandable.”

“We once visited an almost dead planet with no light, no geothermal, not even uranium!Energy is extremely scarce, and there is only a group of tenacious microorganisms that can break down organic matter such as methane.

“What’s so unusual about methane?”Zhang Peng couldn’t help but ask.

He was actually more curious about the high-level life of photons, but he saw that the black obvious words were not obvious, and he could only hold his curiosity.

"Yes, there is nothing unusual about this creature, which can directly use chemical energy."

Black said in his mind, "But we are 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, aren’t you?”

“Why?Do they not need energy?Do they eat each other to survive?”Zhang Peng asked curiously.

Seeing Zhang Peng's curiosity, "black" has a feeling of success.

It scoffed: “How long can devour each other last?”Just like you humans, if you lose all your food, you can support people for millions and tens of millions of years.”

“No.”

Zhang Peng was extremely disgusted with this example of "black" and had a goosebump.

“So, the real answer is... meteorites!”When these microorganisms lack energy, they automatically remove all water and enter a state of wooden fiber-like sleep.Only when meteorites hit the ground and bring a small amount of energy will they re-energize, survive and reproduce.

“All life on a planet, they exhaust all the energy on the planet, all of them waiting for the impact of meteorites... meteorite impact is all their energy sources!”

“You can imagine how sad these lives are.Is this way of survival lucky or another kind of misfortune?”“Black” said very strongly.

“But they’re just microbes...” Zhang Peng said in half, as if he understood something and was silent and no longer said...

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

“This is the big cave where the village is located, and we are coming!”A soldier shouted, and his voice became excited.

This central cave near the crater, it is really huge, just the magma mouth is 10 kilometers wide!Below you can't see the bottom, you can even see thick red magma!

And the whole area is like a high-rise building, and it is divided into dozens of floors, with well-rounded traffic.

Looks like a underground city dug up by the dwarves in mythology!

All the creatures of the underground ecosystem live on this pile of magma.

All underground organisms are not afraid of the toxic gases of volcanoes, these high concentrations of carbon monoxide and hydrogen sulfide gas that can easily poison people are good supplements for them.

The native village of the people is located on the wall of one of the volcanoes, just occupying less than one-thousandth of the entire cave.

On the volcanic wall, there are large and small earth bags and caves, which should be the residence of the lizards.

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

Many lizards lie on the walls and at the door of the village, looking curiously at the human race.

“It seems... they have learned to build villages and have invented earthen walls, the equivalent of our Stone Age!”

A sociologist studied these rough walls with great interest.

He had just wanted to walk over and touch the wall, and the lizard on the top of it caught a scream of panic.
