Chapter 236 Collapse

However, several geologists did not leave. They were anxious to hand over the geological report in their hands to Yu Yifeng.

"Is there anything important?" He asked casually, and then patiently looked through the report handed over.

These geologists did find a few differences.

The first point is that, as Mr. William said, no uranium ore was found on the surface!

It's not that there is no uranium ore, but the quality of the uranium ore found is very low, the reserve is very small, and there is not much mining value.

In the past few months, drones and a large number of reconnaissance robots have explored an area as large as half of Australia, but still no uranium resources with good quality have been found.

Maybe there are, but they are buried deep underground, and people may have missed them.

"Only a few small mines have been found so far, all of which are small mines of 20,000 to 30,000 tons..."

A geologist explained: "It may also be that our luck is not good, and we happened to land in an area with less uranium ore. Similar to the earth, the distribution of uranium resources is also very uneven, with more in some places and less in others. This is normal"

After all, this planet is too big, with a radius twice that of the earth and an area of ​​4 times. And most of them are in the ocean area. The scientist believes that uranium resources can always be found with continuous search.

Yu Yifeng shook his head and said: "If there is really a lack of energy, it can be mined, but now there is easy-to-mine combustible ice, and those small uranium mines that are difficult to mine should be temporarily abandoned."

He turned to the next page and saw the reserve report of combustible ice below, and he was immediately delighted.

According to experts' estimates, the reserves of combustible ice on Nix are 167 times that of the earth!

Most of them are in the Arctic and Antarctic regions and deep in the ocean. Well, even if it is one cent in nine years, it is enough for humans to use, so there is no need to worry about uranium mines!

In short, with methane, energy is not a big problem.

But this geographical report is not over yet.

The second point is that people have found 11 large caves similar to those in the B11 area in an area of ​​10,000 square kilometers!

Even in the volcanic area thousands of kilometers away, similar caves have been found!

This is a bit strange...

The geologist saw Yu Yifeng's thoughtful expression and quickly explained: "These caves may be the unique geological features of Nix. There is no such widespread distribution of caves on Earth!"

"It's very strange. This planet lacks sunlight, the weather changes very little, it doesn't rain much, and only hail occasionally. How are they formed... We have to admit that we haven't figured out the reason for the formation of caves yet."

"Moreover, the nuclear radiation in the cave is generally higher than that in the outside world, which is another very strange point. Could it be that all the uranium mines are hidden in the cave?"

Speaking of this, the geologist was also very puzzled. There must be secrets on this planet that humans don't know.

Yu Yifeng frowned. When he heard this, he seemed to think of something bad, but he couldn't catch this little inspiration.

He suddenly felt sour and cold in his heart, feeling that a strange risk was happening!

This mysterious sixth sense appeared again...

Danger, it's danger!

What is it? !

His brain was working frantically, racking his brains to find this crisis.

...Large caves have also been found in other places, why?

What does it represent, what dangers are there?

Is there a monster that humans can't resist? It's unlikely...

"There is a third point. These caves look very strange. Some of them look like they were eroded by water, while others don't look like they were corroded by some acidic substances!"

The geologist continued. His report only contains these three points, but due to safety regulations, they can't go in to explore for the time being. This group of people is really itching.

Yu Yifeng's heart was beating wildly, and the sense of crisis was getting stronger and stronger, like a thick black fog that had formed a substance!

And... the danger was getting closer and closer!

Suddenly, he had a flash of inspiration in his mind, and subconsciously asked: "How deep did our excavator dig down?"

"Two months, about twenty meters, less than thirty meters." William explained on the side.

Yu Yifeng's body trembled violently, and he thought of something inexplicably...

At this time, a strange sound of stone cracking came into his ears, very subtle, very, very subtle. This sound was mixed in the huge noise of the excavator and the drill, and it was difficult to recognize at all, but he was keenly aware of it.

He suddenly jumped up and shouted, "Go back, all of you!"

Everyone was stunned and didn't understand what Yu Yifeng meant.

But time was too tight, and there was no time to explain. Yu Yifeng moved, pushed and bumped, and pushed them all in like sandbags!

In just a moment, this subtle cracking sound quickly magnified, as if the stone could not support the weight and cracked.

In less than a second, everyone heard a loud "bang".

The entire ground collapsed!

The collapsed ground expanded rapidly, and in less than half a minute, a giant hole of more than five kilometers was created!

The spacecraft, houses, robots, ores, etc. within the range of the hole fell directly downwards at this moment, falling straight down in a way consistent with gravity acceleration...

At this moment, Yu Yifeng felt his whole body suddenly fly into the air, and the solid ground under his feet had been lost. Fortunately, almost everyone had been thrown into the spaceship by him.

"Ah!"

He screamed, and his left hand suddenly grabbed Zhao Yao who fell outside, and the other hand grabbed the threshold of the spaceship, hanging outside like a flying man!

For a moment, all the staff were frightened by this inexplicable disaster and could not react.

Aren't they on the ground? Why are they falling?

Everyone's body is in a state of free fall, some people leaning against the wall, and some people staggering in the air. Because there is no place to borrow strength, no one can move for a while!

They don't know what happened at all!

Yu Yifeng's adrenaline was surging, and the veins on his forehead were popping out. He shouted loudly in the headset: "Pilot! Reverse jet, start the engine and reverse jet!"

No one knows how deep it is below, maybe only a dozen meters, maybe hundreds of meters, or thousands of meters, tens of thousands of meters? !

Even if it is only a dozen meters high, once it falls to the ground, it will definitely cause heavy casualties!

There were collapsed rocks, soil, sand and gravel everywhere around him, all in free fall in the air. Because of the friction of the air, these things had a slight speed difference when they fell, and they collided with each other.

In just a moment, Yu Yifeng felt that he was hit by rocks of all sizes several times.

Fortunately... because the relative speed was not high, the collision was not serious.

"It's going to land!" Yu Yifeng's pupils dilated, adrenaline rushed through his body, and his heart seemed to jump out of his throat. Human power is limited, even if he is a superhuman, wearing power armor, he can't save such a landslide.

He heard a "bang" again, and to his surprise, the ground below was directly smashed down by something falling from above!

Revealed... a larger layer below!

This collision directly smashed Yu Yifeng, who was hanging outside, into pieces, and he felt as if his entire bones were shaken apart. The people inside were also shaken to the ground one by one, and some people even rolled on the ground and hit something.

The power armor he was wearing finally saved Yu Yifeng's life. The mechanical exoskeleton faithfully executed his orders, and one of its mechanical hands firmly grasped the threshold of the spacecraft and refused to let go.

Fortunately, this flight base was not the first to hit the ground. It was only slightly blocked and the impact was still bearable. After the collapse of this layer, a lot of things and the spacecraft fell to the deeper second layer...

Methane is a very common substance in the universe. It is ubiquitous in nebulae that may eventually form stars and their planets and satellite systems, and does not require life to form. For example, Titan has a large number of methane lakes.

Tomorrow is another new year and a new month. I wish all my friends a happy New Year's Day!
