However, there were still a few geologists who did not disperse, and they were anxious to hand over the geological report in their hands to Yu Yifeng. Ｘ

"Is there anything important?" He asked casually, and then, patiently, carefully examined the report that had been handed over.

These geologists did find a few things different.

The first point, as Mr. William said, there are no uranium deposits found on the surface!

It's not that there isn't, it's just that the uranium ore found is of very low quality, the reserves are 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 half the size of Australia, but still no good uranium resources have been found.

Perhaps, but it's just buried deep in the ground, and people don't necessarily miss it.

"At present, only a few small mines have been discovered, all of which are small mines of 20,000 or 30,000 tons......

One geologist explained: "It's also possible that we weren't so lucky and happened to land in an area with fewer uranium deposits. Similar to the earth, the distribution of uranium resources is also very uneven, with more in some places and less in others. It's normal."

After all, the planet is too big, with a radius twice as much as the Earth and an area of 4 times. And most of it is oceanic, and the scientist believes that uranium resources will always be found with continuous searches.

Yu Yifeng shook his head and said: "If there is really a lack of energy, you can mine it, but now that there is combustible ice that is easy to mine, those small uranium mines that are difficult to mine will be abandoned for the time being." ”

He flipped to the next page, and he had already seen the report on the reserves of combustible ice below, and he was immediately overjoyed.

According to experts' estimates, the planet has 167 times more combustible ice reserves than Earth!

The vast majority are in the Arctic and Antarctic regions, as well as in the depths of the ocean. Well, even nine years of dime is enough for human use, what round of uranium mines!

All in all, with methane, energy isn't much of an issue.

But that's not the end of the geography report.

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

Similar caves have even been found in volcanic areas thousands of kilometers away!

That's a bit weird......

Seeing Yu Yifeng's thoughtful expression, the geologist hurriedly explained: "These caves may be the unique geological appearance of the Nicks Star, and there will be no such common karst caves on the earth!" ”

"It's very strange that this planet lacks sunlight, the weather changes very little, it doesn't rain much, only the occasional hail. How are they formed...... I have to admit that we have not figured out the cause of the formation of the cave for the time being. ”

"Moreover, the nuclear radiation in the cave is generally higher than that of the outside world, which is a very strange point, is it possible that all the uranium ore is hidden in the cave?"

Speaking of which, the geologist is also very puzzled, there must be secrets on this planet that humans do not understand.

Yu Yifeng's brows furrowed, when he heard these words, he seemed to think of something bad, but he couldn't grasp this aura.

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

This mysterious and mysterious sixth sense has reappeared......

Danger, is danger!

What is it?!

His brain was running wildly, racking his brains to figure out the crisis.

…… Large caves have also been found elsewhere, why?

What does it represent, and what are the dangers?

Could it be that there are monsters in it that are difficult for humans to resist? Unlikely......

"And the third point, these caves look very strange, some of them seem to have been eroded by the water, and some of them don't, as if they were corroded by some kind of acidic substance!"

The geologist still said. That's all there is to his report, but due to safety regulations, they can't go in to explore it for the time being, and their group of people is really itching.

Yu Yifeng's heart beat wildly, and the sense of crisis intensified, like a thick black fog that had formed a substance!

And...... The danger is getting closer!

Suddenly, a flash of inspiration flashed in his heart, and he subconsciously asked, "How deep did our excavator dig down?" ”

"Two months, about 20 meters, less than 30 meters." William explained on the side.

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

At this time, a strange cracking sound of a stone reached his ears, very subtle, very, very subtle. The sound was unrecognizable in the loud noise of excavators and drillers, but he was keenly aware of it.

He jumped to his feet and yelled, "Go back, give me all back!" ”

Everyone was stunned, and they couldn't understand what Yu Yifeng meant.

But the time was too tight to explain, Yu Yifeng's body moved, pushed and bumped, and all pushed them in like sandbags!

In just an instant, this subtle cracking sound quickly amplified, as if the stone could not support the weight and cracked.

Less than a moment later, everyone heard a loud "boom".

The whole ground has collapsed!

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

Ships, houses, robots, ores, and so on within the scope of the cavity fell directly downwards at this moment, falling straight down in a way that conformed to the acceleration of gravity......

At this moment, Yu Yifeng only felt that his entire body was suddenly empty, and he had lost the solid ground under his feet, but fortunately, basically everyone had been thrown into the spaceship by him.

"Ahh

He shouted, grabbed Zhao Yao who had fallen outside with his left hand, and grabbed the threshold of the spaceship with his other hand, hanging outside like a flying man!

For a while, all the staff were frightened by this inexplicable disaster and couldn't react in a daze.

Aren't they on the ground, and why are they falling?

All of them were in a state of free fall, some leaning against the wall, some staggering and falling in mid-air. Because there was nowhere to borrow, no one could move for a while!

They simply don't know what's going on!

Yu Yifeng was full of adrenaline, the green tendons on his forehead burst out in a hurry, and he shouted loudly in the headphones: "Pilot! Reverse Jet, start the engine Reverse Jet! ”

No one knows how deep it is below, maybe only a dozen meters, maybe a few hundred meters, or a few thousand 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 are rocks, soils, sand and gravel that have collapsed everywhere, all of which are in free fall in the air. Because of the friction of the air, these things have a slight difference in speed when they descend, and they collide with each other.

It was just a split second, and Yu Yifeng felt that he had been hit several times by large and small stones.

Fortunately...... Because the relative speed is not high, the collision is not serious.

"It's time to land!" Yu Yifeng's pupils dilated, the adrenaline in his body was rushing, and his heart seemed to jump out of his throat. Manpower is sometimes exhausted, even if he is a superhuman, wearing power armor, he can't save such a landslide event.

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

Revealed again...... A bigger layer below!

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

The power armor worn on his body finally saved Yu Yifeng's life, and the mechanical exoskeleton faithfully carried out his orders, and a mechanical hand firmly grasped the threshold of the spaceship, and did not let go.

Fortunately, this flight base was not the first to hit the ground, but it was only slightly hindered, and the impact was still bearable. After collapsing this level, a large pile of things crashed into the deeper second layer with the ship...... r
