Chapter 275 A World Without Fire

Yu Yifeng couldn't help but sigh: "It's amazing! This thermonuclear organ is like a temperature difference battery, and it can actually use heat energy to 'charge' itself."

"Their body structure is also evolved with thermonuclear as the core. The long tail makes it easier to cause temperature difference in the body."

"This organ looks more advanced than the human digestive system. The key is to maintain the temperature difference between the inside and outside of the body to flow heat. Their bodies can stay in the high temperature zone of 60 or even 70 degrees for a long time, and they still feel very comfortable."

Speaking of this, Yu Yifeng looked disgusted. Humans actually rely on food as a source of energy. It's really too low-end and very inconvenient.

Although the Nix people also need to eat in small amounts, the number of times is much less than that of humans in general, and food is not the main source of energy.

"If humans also have such an organ, how much trouble can be saved, how much time can be saved, and sleeping can be..."

But when he saw Yuriko's frowning expression, he quickly shut up.

This girl has basically no other hobbies. The only hobby... is to enjoy food, or this is also a unique culture of humans.

Yu Yifeng changed the subject and said, "So basically all underground creatures have similar thermonuclear organs, right? Even the indigenous lizards should have them, right?"

Yuriko nodded and hummed. But she still said seriously, "Yes, a large number of similar organs have been found in many underground creatures, which has a certain reference significance for our biology. However, the Nix people and the indigenous lizards are two different species after all, and their body structures are still different."

"What's more, over the past ten million years, the ecological environment of Nix Star seems to have undergone very significant changes!"

"More than ten million years ago, there was more methane, carbon dioxide and sulfide in the atmosphere, and these gases can also provide a certain amount of chemical energy. The continuous meteorites and volcanic eruptions can also continuously replenish these substances."

"For some reason, there are now fewer carbon-containing substances in the atmosphere, so the 'thermonuclear' in the indigenous lizards has been greatly degraded. They still need to consume a certain amount of food, unlike the Nix people, who almost do not need a small amount of food."

"Only some underground black worms and long plants are relatively pure geothermal energy creatures..."

This is a relatively novel discovery.

In some ancient books that have been discovered, the composition of the atmosphere at that time is clearly recorded: indeed, as Yuriko said, the atmosphere at that time had higher concentrations of methane, carbon monoxide, etc., and the oxygen content was very low.

Many experts speculate that perhaps the mass extinction of the Nixes was related to the huge changes in the environment! This possibility is very high.

Of course, there is another possibility that the changes in the atmospheric environment occurred after the extinction of the Nixes. No one knows about this kind of thing... People need more evidence to judge.

Yu Yifeng paused and returned to the original topic: "In this case, thermal energy is the best source of energy for the Nix people, not food. They can recover their strength by just lying on the heat source and taking a nap, and they don't even need to eat."

"This is too different from humans, so their way of thinking is very different from humans, and they don't need agriculture."

"If the first great sage is the one who draws the star map. Then... the second great sage is the one who risked his life to fish out a basin of magma. They need temperature and heat. Their digestive organs are not very perfect, and eating is not a good choice, which will affect their lifespan."

"...Why don't they have fire? Wouldn't it be more convenient to use fire, just like lizards?" Yu Yifeng suddenly wondered with a flash of inspiration.

Yuriko rolled her eyes at him and said unhappily, "Because there was almost no oxygen in their atmosphere at that time, or the oxygen content in the atmosphere was very low, less than 0.1%, and ordinary combustion reactions could not proceed!"

"What they can use is the thermal energy of magma and the chemical energy in the air, and they don't need to breathe oxygen to carry out redox reactions in their bodies. So these organisms are generally anaerobic organisms."

"Without oxygen, there will be no violent combustion, that is, no fire!

"This is really beyond our imagination... We don't know how their civilization developed. "

Speaking of this, Yuriko said in an inexplicable tone: "You can imagine that a civilization without fire... a civilization that can only use the temperature of magma has developed to the modern era or even surpassed the modern era..."

The discovery that the Nix civilization has no fire is simply epic! It is an extremely shocking thing for humans, and even subverts the traditional thinking of sociologists.

It is difficult for humans to imagine that a civilization without fire has developed a brilliant modern culture!

Is such a civilization...

more powerful than humans?

"All this is because... their culture extremely respects wisdom and the title of "great sage"!" Yuriko looked at Yu Yifeng and said faintly.

After saying this, the two fell into a silence.

A world without fire is no longer a nightmare, it is really... hell!

If there is no fire on the earth, humans will still be in the earliest stage of ignorance, similar to the current gorillas.

Humans accidentally mastered fire, and gradually learned to cook meat and fish, which enabled humans to spread from the tropical jungles of Africa to the whole world, mastered the basic ability to drive away wild beasts, survived the coldest ice age, and provided the possibility for the further evolution of humans later...

In the past, Nix Star had no oxygen, of course there was no fire, everything... nothing!

Even the steam engine and internal combustion engine later developed by humans used the combustion phenomenon. But more than 10 million years ago, in a world with very little oxygen... even if there was methane everywhere, there would be no combustion phenomenon, and the available energy was greatly reduced.

In this way, if the starting difficulty of Earth civilization is "1", the starting difficulty of the indigenous lizard civilization is "10", which is more difficult than that of humans.

Then... the starting difficulty of Nix civilization is more than 100 times that of Earth, that is, 100!

... A veritable hell difficulty!

There is not even fire, so are primitive people allowed to use nuclear energy directly?

"It is really hard to imagine how society changes and how the technology tree jumps in a civilization without fire..."

Faced with this almost unsolvable problem, Yu Yifeng also felt very incredible.

The endless universe always has so many unexpected things, which bring endless surprises to people.

Of course, the universe is so big, and humans are definitely not the strongest race, nor the smartest race. Even the most narcissistic people have to admit this.

And now, a civilization has developed without fire... They have overcome difficulties that humans can hardly imagine.

Overall, they are definitely stronger than humans.

This is just a planet that humans have encountered casually. In the endless universe, will there be a stronger race than the Nix civilization?

Of course there is! The Nix civilization is definitely not the strongest civilization.

It is a civilization eliminated by the "Great Filter"!

Just thinking about it, Yu Yifeng felt a chill...

He suddenly had a sense of extreme insignificance in his heart.

The brilliant starry sky, the vast universe, if humans do not step into the starry sky, they will never know so many strange things. If they do not step into the starry sky, humans will always be obsessed with the fantasy town they have imagined, fearless and ignorant...

At present, people have only so much historical information about the Nix civilization, and it is not very complete.

The Nix civilization, which has already declined, still has a lot of mysteries to be solved...

How did they develop? How did they evolve into modern civilization? And how did they decline? Until now... it is still an unsolved mystery.

However, Yu Yifeng is not in a hurry, and humans are not in a hurry either. As long as they search slowly, they will always find some clues...

Even if you are anxious, you can't be impatient. Everything needs an opportunity to promote...
