Half-immortal civilization

Seeing that the height from the ground was only about two meters, Zhou Xu got rid of the rope and jumped down.This kind of behavior is actually very risky, but at a distance of only two meters, it can already be seen clearly that the ground is all solid rocks.

This is a lava lake that has cooled, and now it presents an overall gray world; occasionally there is a little reflection, which is some crystals in the rock; there are also some metallic colors.In short, in this oxygen-free environment, a large number of metals exist in the form of simple substances.The cooling after the high temperature makes the surface of some metal particles black and shiny.

Measured with an infrared thermometer, the temperature here is only ten degrees below zero. Obviously, this is a planet that has completely cooled down. Unlike the earth, the deeper it goes, the hotter it gets!In some rocks, some metal crystals isolated due to cooling and contraction can also be seen.After pawing and pulling a few times, I found a few irregular iron beads.

It really is a treasure!Zhou Xu nodded secretly, thinking that the boss hired these geologists to investigate the interior of the moon and look for metal deposits, which is definitely a stroke of genius.If it is really possible to find a large number of tens of billions of metal elements in the depths of the moon, it will bring a huge boost to the space construction of the master company.At that time, the metal smelting alone will save the master company at least trillions of yuan in investment and about three years of time!
Especially in terms of time, in this ever-changing world, time is also a more precious resource than money!In particular, there is no such thing as returning and reusing this thing, what is past is past!Maybe someone said.Go back to the past, but according to the existing scientific theory, it is impossible for human beings to really go back to the past!

To give an example of a paradox: If a person can travel back and kill himself who was assembling a pistol a few minutes ago; then it is said that the pistol assembly failed-then how did this person get his future pistol?This is a scientific paradox; and in science, such means are often used to verify the rationality of certain things.

After looking around, it was already a vertical, solidified crater, with a radius of about ten meters square, and there were some holes around it, the largest of which was three meters high.

"It's safe down there. It's solid rocky ground. Come down now!"

"Okay, please pay attention."

Along the rope, all the people came down one by one, 50 people.Plus a lot of supplies.Gathered in this crater which is only ten meters square.Somewhat crowded.

Zhang Chen is doing detection; the surrounding material composition is one aspect, and more importantly, in the surrounding large and small pores.Find the passage to the next level of objectives.

Not that bigger caves are better; some caves are dead, while others have a narrow entrance but are very spacious inside.

"This!" After searching for a long time, Zhang Chen locked a cave, but the outermost layer was only one meter in size, and the inside was two meters in size.It is not an easy job to climb through such a hole.The best way to find such caves is to judge by echoes.Fortunately, in this cave, there is gas that can transmit sound.

"I'll come first!" Li Yun, a young employee from a master company, volunteered.Put down the irrelevant items and only carry the necessary supplies, such as compressed air tanks, lighting equipment, pistols and daggers, etc., and slowly climbed in.

"Be careful, pay attention to the many sharp crystals on the surrounding rock walls, don't scratch the space suit." Zhou Xu worried.Here, once the space suit is damaged, although there will be no danger to life in a short time, rescue work is not easy to carry out.It will take a day for the next batch of supplies to arrive.

"Don't worry, captain, I have prepared tools!" Li Yun raised the rock in her hand; yes, this is Li Yun's tool.Of course, he also carried exquisite tools on his body, such as hammers and chisels;Use the rock in your hand to smash some sharp rock crystals around; this process is very slow, and you have to look for crystal particles and destroy them while moving forward.

After more than an hour, Li Yun's voice came from the headset: "It's safe inside, come in. The temperature inside has a slight upward trend, minus 12°. It feels like there should be a heat source inside the moon, and it's not completely cooled. .”

Zhang Chen: "This is for sure. According to calculations and observations, there should be a core inside the moon with a temperature of about 1000 degrees, which is a remnant of ancient temperatures. It is not even ruled out that there is still lava inside the moon. It is better to be careful." .”

Li Yun: "Don't worry, there is no danger here! And it is very spacious. The terrain ahead seems to have dropped again."

Entering the cave again, the detectors started to sound.

"The radiation exceeds the safe radiation of the human body, everyone pay attention; if it exceeds three times the safe radiation of the human body, we must withdraw." Zhang Chen was a little nervous.Although this problem was considered before, it was not expected that the radiation would already exceed the standard here.It is less than 500 meters underground.

"Teacher, I just measured that the iron content of the rocks here is as high as 33%, and the overall metal content is as high as 42%! And most of them exist in the form of simple substances, which already have the value of development."

"Hmm. Looks like the Moon really is a bonanza. We're going ahead. Monitor radiation strictly."

At the end of this cave, everyone began to lower the second rope.After descending more than 60 meters, I came to a cave again, but compared with the previous cave, this place is a bit more beautiful!

A large number of rocks may have formed a branch-like structure due to the rapid cooling rate, and just like this, the branches traverse this underground world that can't be seen at a glance.Everyone can only stand carefully where the "branches" fork, and try to choose a relatively wide branch.

"Didi, the radiation has reached 4 times, and prolonged exposure will cause permanent damage to the human body. It is recommended to evacuate immediately!" Such reports have already made some old experts start to worry.

"Wait a minute, let's measure the elemental composition here.

At the three o'clock direction, the content of iron atoms is 47%, copper atoms are 6%, oxygen elements are 10%, silicon elements are 4.3%...

At seven o'clock, 32% iron atoms, 17% copper, 3% silver, 12% titanium...

……

According to a comprehensive assessment, it contains about 38.76% iron.If the ore is crushed, iron powder can be quickly screened by magnetic separation. "Finally, Zhang Chen concluded, "Zhou Xu, I think we have reached the preliminary intention of searching for iron ore.Next, it depends on your company.Unless the equipment is upgraded next time, we won't be able to exert much effort. "

"It's already very good. I didn't expect that there is such a place not far from the base, not deep underground. I just don't know if it's like this on the whole moon, or just a few places."

"I think this should be a common phenomenon on the moon." Zhang Chen looked at the surrounding environment. The dark rocky jungle gave people a gloomy feeling.It's too big and empty here, and the only lighting can't bring enough brightness here.

"Well, go back to the ground first. The elderly are limited, young lads, let's step back!"

Going back is not so easy. Along the way, we have to climb three rock walls, which is a great test for the elderly; although many heavy objects have already been borne by young people.

Back on the ground, Zhou Xu mobilized the discovery here into the hands of Zhang Jingyuan.To be precise, it was sent to the space shuttle in space, and then forwarded to Zhang Jingyuan. (To be continued..)
ps: The outbreak is over today, no need to wait.
