Sure enough, after the intermediate vehicle shuts down the engine, the black bugs gradually abandoned it and stopped attacking.

Even the black worms that had been parked in the car slowly flew away.

He breathed a sigh of relief in his heart.This method works, these damn bugs are really attracted by the heat!

Looking out the window, the worms kept coming out of the caves in all directions, like a pile of black, squirming deserts, like the piles of holy beetles in the movie.This number is too terrible, if there is a phobia of people are expected to be scared to death.

The number 100 people hiding in the car are also in solidarity, scared, and completely dare not move.It is good to have this refuge, otherwise, perhaps all will suffer misfortune.

This worm tide was like madness, all agitating its wings, and kept rushing in the direction of the falling base.

All because of heat!

The engine of the falling spacecraft is in a period of temperature rise, the core temperature is enough to be thousands of degrees, and the sodium vapor is even burning!At the same time, another water-cooled device ejected a large amount of high-temperature water vapor.

The heat brought by this nuclear engine is much higher than that of several incendiary bombs, so this group of things is crazy to attract the past.

In the front track car, some people are mourning the dead, especially the relatives and friends of the deceased, immersed in an atmosphere of sadness and pain.

There were also whispers of discussion, frowning and meditating, trying to solve the immediate crisis.

How did such an underground ecosystem form?Why do insects produce acid in their bodies?Why do they have such a strong heat?

Time passed by, and in the blink of an hour and a half, the insects outside were still flowing, there was no sign of decreasing, and in Yifeng's heart it was becoming more and more anxious...

Their time was not unlimited, and it was clear to all that the nuclear engine would explode in a few hours.

Not exactly, six hours!At this close distance, they will be affected by a nuclear explosion!

Now it is still too close, not a few kilometers in total, hard to eat nuclear bombs is not a very good choice.

“How many professors have any results?”

Yu Yifeng asked anxiously, "I don't know how many these damn bugs are, we can't wait indefinitely!"You have to find a way to get out of here!”

A energized by the black paint of the fire, the biologist who escaped from the worm heap was stupored, and then said with some fear:

“We agreed after discussion that heat is the main energy source of the underground ecosystem!”Just as important is light to plants!However, because the scarcity of geothermal is not as sufficient as light, it also leads to the fact that organisms here are generally more aggressive.”

"Only aggressive creatures can occupy the best places."

"And our power A will also release higher heat, especially in the heat dissipation area at the bottom right, at least 40 or 50 degrees, so they will be attacked by them!"

Yu Yifeng nodded, he touched his hand, and the heat dissipation area at the bottom right was indeed the most corrosive.

And the fact that the worm does not attack the cold track car indirectly proves this.

Heat is the only thing that attracts them!

The biologist thought for a moment and continued: "We suspect according to various phenomena that these huge underground caves are corrified by the acidic liquid of the blackworm!"Because the deeper the cave corrosion, the closer the geothermal heat is!”

Just as all plants on Earth have a kind of light-oriented, involuntarily growing in the direction of light, and these subterranean organisms have an instinctive tendency to heat!Geothermal means stable energy, so they flock in the direction of the spacecraft!”

“There’s a high temperature zone, and maybe they’re mistaken for finding a new geothermal source...”

He nodded, he wanted to ask other more important things, but still pressed on the impatience, and continued to listen.

The biologist picked up the body of a worm and said, “As for the acidic liquid in their bodies ... we guessed that it may have evolved to corrode underground rocks, which is the result of natural selection!”

"Thousands of thousands of meters of rock deep underground, because of the relationship of ultra-high pressure, are usually extremely hard, such hard is not the soil of the surface, it is too difficult to make holes!"Especially when large rocks are encountered ... and these insects cannot have large drilling rigs like humans, it is impossible to break through the rocks.”

"Only generations of acid corrosion can be further down!"Closer to the underground heat!Heat is their life!”

At this point, it seems that scientists have forgotten the thrillingness of the moment, and have become a little shocked, excited and fanatical.

Life is so magical that Darwin’s theory of evolution has been proven once again: the survival of the fittest, the elimination of the unfit, and the emergence of more tenacious life under cruel natural selection.

There is no sun, only geothermal!

Then a group of strange creatures that can make perfect use of geothermal energy has appeared!

In order to get closer to geothermal, they make holes, corrode, dig the ground, and can do almost everything.

Only by relying on geothermal energy can we survive!This is a truly cruel natural selection that is much harder than the environment on Earth!

“So... their acid is particularly good for our helmets.”This is the acid that has evolved for hundreds of millions of years, and it is dedicated to corrancing the acid of the rock!”

That's a good explanation...

The helmet worn on the head is made of nano-silica plus some organic additives, and there are also silica components.Therefore, it is not possible to eat the corrosion of black insects.

Another scientist took the topic, some feverishly said: "We guessed that these black bugs can even absorb heat energy directly in the higher temperature area and synthesize organic matter."

“Maybe they can replace plants as producers!”A insect producer who can replace plants.No... this is just a guess, but anatomical research is needed.”

"When they absorb heat, they habitually use a part of the energy to synthesize an acidic liquid, and then slowly corrode this part of the rock, so that the cave dug deeper ... the corrosion accumulated over the years, coupled with the washing effect of the water flow, formed such a large-scale cave!"

“And I just found that this acidic mixture of silica melts, once solidified, forms harder rock!”This re-agulated rock is extremely hard, so it reduces the occurrence of cave floor landslides!”

“Yes, it must be so!”

The first unsolved mystery was solved.

The distribution and the caves under the entire planet are actually corroded by black bugs, which is incredible!

Such a huge project, even the underground void of the entire continent, even humans can not do, but it was done by small insects.

Maybe it took them tens of millions or even billions of years?

Everyone was thinking, even Yi Feng froze, this is the shock of life...

And great!

In the previous environment of superior earth, this is not dare to think of great achievements!The eight wonders of mankind, the amount of engineering combined to have one billionth of the underground caves?

After a long time, Yu Yifeng slowed down God and remembered the right thing: "Professors, is there any way to prevent the worm from attacking us?"It’s been too long and we have to leave!”

Although the expert is not very sure, but still said: "heat, ultimately heat, we better not let the power armor heat, they will not dock, will not attack!"Maybe that is it!”

“They’re definitely cold creatures!”

Don't let the power car emit heat?

What is the way to meditate on Yi Feng's eyebrows?Take off the power armor, it is impossible!

People's power armor can not be like a crawler car, directly off.If the energy system is closed, all kinds of life-saving facilities are not allowed to move in dozens of kilograms of iron clothes.

But the start of the power armor will inevitably emit heat, and then suffer from the attack of the insect tide again!

This is a dilemma!

If there is a spacesuit, it is not enough... If a small number of bugs docked to secrete acid, the spacesuit will be damaged immediately.

Can't get a layer of mud on the power armor?

It’s better to be able to cool things!

When people like Yi Feng and others meditate, what can cool down?
