Half-immortal civilization

Once life was discovered, everyone's passion for exploration broke out.Seeing that the Great Rift Valley is very stable, someone suggested whether it is possible to go down and have a look.Especially if you want to see if there is a weird ecosystem underneath.A world of underground water generated by heat generated by gravitational friction, a world of life hidden below 100 kilometers, and a world of life 7.78 million kilometers away from the sun.

In fact, some people think this way: finally, there is an alien planet full of oxygen, and the atmospheric pressure below it is equivalent to that of the earth. If you can take a breath, it will be worth it!The temperature here is very low, but you can set up a tent!And it's about minus 40 degrees, and it's no problem to breathe carefully-the earth's Antarctic is more than minus 60 degrees, and some people can breathe directly!
Not to mention, although the Great Rift Valley has a depth of at least 56 kilometers, which is almost twice the height of the earth's stratosphere; even if the gravity here is low, the oxygen mass is large, making the low atmospheric pressure here almost equal to that of the earth.Such a strange extraterrestrial planet, if you don't take a good look at it, you'd be too sorry for yourself, wouldn't you!
However, it is still very dangerous to explore a strange planet, especially this kind of frozen world is very fragile.Perhaps, the next moment it is subjected to the gravitational pull of Jupiter, new cracks will be created.You know, just because of the friction caused by Jupiter's gravity, an underground water world has been formed. One can imagine the huge influence of its gravity and the degree of activity of this ice world.

"Find a place at a depth of 56 kilometers to investigate first. The ice layer here is thicker, which is relatively safer. And it is closer to the ground. Once danger occurs, it is better to escape." Li Canglan told those who want to go directly to the depth of 100 kilometers Hole to persuade people looking for life.It's good to be adventurous, but it's not good to be stupid and not care about your own life.Especially now that the earth's exploration activities are still in the training period, casualties will always dispel some people's enthusiasm.

Reinforced carbon fiber mixed with olefin rope, definitely the strongest material available today.This kind of rope that can be used to drag the planet, the thickness of a hair, can lift hundreds of kilograms.The gravity on Europa is very low, only a little over 1.3.A person fully wearing a space suit has a mass of about 200 kg.And here, the expressed weight is only 26.5 kg.

It is said that the organic fiber made by the master company imitating spider silk has also entered the final public relations stage, and its strength is stronger than the current carbon fiber.but.Organic fibers are not resistant to high and low temperature, aging and so on.

Only half a day.A small base is built.Mainly some fixed winches, rescue devices, maintenance items and so on.after all.This altitude is at least 56 kilometers, and it takes a lot of effort to transport materials back and forth.The best way to do this is to ship items directly below as much as possible.Then strictly monitor the security situation here, as long as there is no danger, there is no need to come up.In particular, there is sufficient oxygen and pressure below, and the temperature is not unbearable minus 170 degrees, minus 40 degrees, pure oxygen, and approximate atmospheric pressure. This is very good in the cosmic environment; no, to be precise, it is already considered a miracle. land.

As long as a small amount of energy is used, the oxygen and water necessary for life can be obtained. It can be said that this place is simply a holy place for exploration and learning!It is a pity that it is a little far away from the earth, and it is close to Jupiter in space, so the radiation and magnetic field are a little big.

The winch roared slightly, but the thin atmosphere here was enough for humans to hear the sound.

Li Canglan looked around: "Get ready. Get ready, everyone, get ready. Finally, I would like to declare that it is extremely dangerous to venture below. At an altitude of 56 kilometers, once danger occurs, there is no time to move."

"Hey! Captain Li, what you said is wrong. Since we dare to come to space exploration, we are not afraid of this. To be honest, I am willing to come because of the danger." A member of the small adventure team replied loudly.

Li Canglan looked at this person and nodded his approval.This person is an adventure team that registered relatively late, with only 30 people, a small spaceship, and a simple name: Stone; and this person is the captain of this adventure team, Shi Yuming!A hot-blooded youth group who just graduated from college and applied for a bank loan.However, after three years, the loan has already been repaid, and it is ready to buy a second spaceship after returning to the voyage; it is a small example of the master company's external publicity.

There are more than 5 adventurers on Europa now, but more than half a day has passed, and everyone only has [-] hours left—for safety reasons, even if it is relatively safe here now, Li Canglan also forces people to take turns to rest, and The resting position is the spaceship in space.After all, there were too many uncertain dangers to live on such a cold, alien planet.Maybe when you fall asleep, the ice layer under your body will crack, and then you will all enjoy the exotic free fall,

However, the remaining five hours are enough to put some materials, etc., into the world below, and complete the reserve exploration work.

Li Canglan led the employees of the master company to lead the way, followed by the national team, and finally the general adventure team.There were hundreds of people in the first group, and they were mighty—hanging in mid-air, and falling slowly under the action of the hoist.

Here, after all, is an alien planet, a strange frozen planet, and a strange life was discovered just now.This makes everyone who is descending, the boss of eyes etc.Although, in this gloomy world, everything is very hazy.

"Wow!" Shi Yuming, who was in his 20s, was surprised and shocked everyone.In an instant, all the hoists stopped, and the people around followed the light of the flashlight and saw an unexpected thing-a frozen creature that resembled an octopus and jellyfish assembly!In the cold ice, the creature has a faint red color, a huge hijab that looks as soft as yarn, and more than a dozen long tentacles, like streamers, sealed in ice.Everyone can only see a rough shape through the broken ice.

"Keep going down. This object is at least 10 meters long; moreover, it is already ten kilometers deep, and it will be very difficult to dig out. We might as well go deeper and look for it below." Li Canglan made a decisive decision.

The winch continued to work, and everyone continued to fall.But the falling speed has been much smaller.In addition, the detectors launched earlier were more about exploring the safety of the ice surface; but now, they are beginning to explore the existence of living things.

As it descended, in the cold ice, frozen creatures began to diversify.The most numerous creatures are those like water mist, which are densely packed in the cold ice, and if you don't look carefully, you can hardly see them.Obviously, this should be the life at the lowest end of the food chain.And the biggest one is the huge creature that I saw just now.But they are all frozen, so they can't see clearly.In addition, all creatures give people a jellyfish-like feeling: translucent, hazy like water mist.
