"Bang, bang."

As soon as Sun Wuru came out of the machine, he heard the sound of the small fireworks exploding. It was the first time he had tried teleportation, and he was still feeling a little dizzy, worried that something was missing from his brain and hadn't teleported.

But fortunately, the voice of "friends" is still there.

"Welcome to the Muinak Desert!!" The cheers rang out with the sound of the salute, and Chuan Wu, who was in front of Sun Wuru, was hung up by the streamer, and was looking at Sun Wuru behind him with a wry smile.

He was fitted with a prosthetic eye and a prosthetic leg, and Sun Wuru almost didn't recognize him.

"Don't worry, if you don't succeed in teleporting, you won't be able to come out." Chuanwu helped him: "Take a deep breath." ”

The feeling of Venus in his eyes gradually dissipated, and Sun ruthlessly raised his head, and there was a huge desert in his eyes. The sun poured wildly down on him, but he didn't feel the slightest warmth.

In the midst of this golden desert, more than a dozen researchers sat in front of their computers, holding salutes and celebrating the arrival of three newcomers.

"This is ......" Sun Wuru was still a little confused.

"Holographic projection only." The first middle-aged man in a yellow uniform stepped forward, held Sun Wuru's shoulder, stretched out his hand and gently swiped on this desert, their vision was instantly raised, and they looked down on this desert from the sky: "This is the bottom of the great desert north of Muinak. Satellite imagery suggests that the desert has been abandoned for hundreds of years, but in reality, many countries have secretly set up sites underground. ”

"Because of the minerals?" Kawago stood beside him.

"Because of minerals." The man nodded: "Now there is no shortage of energy, but relatively speaking, rare metals in various countries are still very limited." This is the territory of the Oss Country, and it is their right to mine or sell it, but we will pay close attention to who it sells it to and how much it is priced. It has replaced the oil-rich Middle East as a new point of contention. This one, and this one, we suspect to be the eastern country and the European Union's quarters. ”

"Or is it just suspicion?" Qin Chu'an finally came out of the machine as well.

"The situation under this desert is very complicated, with tens of thousands of caves and canyons all over the ground, which are rich in minerals, and it is difficult for us to build a complete monitoring system without enough resources. However, the other party should be the same. The middle-aged man said, "This is not a federation after all, and we don't want to be tongue-in-cheek." ”

The middle-aged man patted them on the shoulder, snapped his fingers, the holographic projection turned off, and they returned to the familiar research institute. It's a hot desert overhead, but it's cool. The whole country has abundant solar energy resources, and even if other resources are poor, they can import the food and fresh water they need from other countries.

The Great Desert, which has been forgotten for hundreds of years, has actually been a piece of fat meat that can not be found in the eyes of all countries.

"Alright, alright." The man suppressed the cheers in the laboratory, there had not been a newcomer here for a long time, even if it was a law enforcer, in the eyes of these researchers, it was already strange: "Let me introduce myself, Huang Sanshao, the head of the Federal Experimental Center in Muinak, is also a student of the fifteenth class of Tius Academy. There are also your seniors here. He gestured to a researcher sitting not far away, who greeted them and lowered his head to go about his research.

Following Huang Sanshao all the way, Sun Wuru could see the majestic rough stones underground, as well as automatic machinery like "Friend" and "Kars". In order to prevent the enemy from blocking their electromagnetic signals, a completely new self-circulating artificial intelligence has been built here, and of course, the self-destruct program has been written.

"The data here is still useful." The "friend" immediately synchronized a piece of data and displayed the results of the investigation team during this period in front of his eyes.

As Huang Sanshao said, the underground space of Muinak is really very wide.

The deepest natural cave is more than 6,000 meters, and a large amount of geothermal rock can be explored at that depth. And this number is constantly being refreshed. The minerals contained in the rock wall are even more valuable.

But that's not what they're here for.

"I have your information, three S-class students, not bad, very good, just." Huang Sanshao took the four of them to a lounge, asked Manzhu to sit down first, then looked at Sun Wuru and asked, "What is your gift?"

The twentieth class of Tius Academy's S-class students have passed a year, but they have not yet awakened the gift.

But it is clearly written on the information that Sun Ruthless's physical fitness is level six.

So he was a little confused.

"It's true that there are no gifts, and the specialty is fighting. Maybe it's because it's better to play. Sun ruthlessly recounted the reply given by his "friend".

Looking at his eyes, Huang Sanshao finally nodded. It is rare for a second-year student to have a physical fitness of level six, and it is reasonable to say that he is specifically responsible for hand-to-hand combat, after all, the current team really lacks a person who can resist and fight.

But level six, it seems to be a little worse. Chuanwu's physical fitness is also nearly level six, but he still has gifts.

The task is done by people who can win battles, not students who come here for internships.

Hopefully, the "friend" will not go wrong. Huang Sanshao thought to himself. Next, he pulls up the holographic projection and tells them the cause of the mission.

Only then did Sun Wuru know that a month ago, a report was not sent to the Federation through an encrypted signal, but was picked up by the injured Lin Wei from thousands of miles away.

A report with higher S-level permissions, after Huang Sanshao read it at first, he didn't know who to give it to.

The responsibility of the federal investigation team is to find out mineral intelligence, monitor the mining of rare metals in the country of Ouaisi, and find out the whereabouts of other countries, which Huang Sanshao believes has done very well in the past few years.

Many countries have set up investigation teams here, like a few overseers, watching the country of ISS mining these rare metals, and then they will wait for the price to sell, or take what they need. Few people dare to make small moves, and if they are discovered by the Federation, Huang Sanshao may personally go to warn them.

But in the process of descending, the people of the country of Oaisi discovered a strange cave.

It is already 4,000 meters underground, and humans can only burrow like ants in this vast place than the surface world, like the rhizomes of plants.

Day after day, the worker who operates the machine can only see the monotonous shale on the screen, sometimes a striking pale blue or gold, and he has to submit a report to determine whether it has been mined or not, and then he has to continue drilling.

Other than that, he had never seen anything else.

Until that day.

The drill bit that went down had cut a hole in the area they had explored together, and the computer told them it was a rich vein.

The computer never fooled them, so the staff member was relieved until the huge drill bit fell into a hole.

There is light in the hollow, and it is sunlight. Through the camera on the drill bit, the staff member also saw green grass and clear water.

It's like falling into another world.

Three seconds, almost the next, the screen went dark. ISS lost a large drilling rig and also recorded the three-second video.

But that's just the beginning.

Over the next few days, ISS found that many of their projects were being put to rest. In an area up to 4,000 meters deep, it seems that a strange force is destroying their rigs.

So the Federation had to go down to investigate in person, which had affected the production of minerals, and he even met people from the East and the European Union underground. His gift was the ability to separate the rocks and move freely between the rock formations, which was the main reason he was sent here.

Therefore, this information was known earlier than other countries.

Because he saw the lost oasis with his own eyes.

"My detector shows that it is 4,325 meters underground, with the right temperature and humidity, and there may be artificial sunlight overhead. This depth is rich in geothermal energy, and with enough technology, it is possible to obtain enough energy to squander. But the problem is that this space appeared out of nowhere. Huang Sanshao's face was solemn, the camera he was carrying kept part of the footage, and in the lounge, Sun Wuru was able to get a glimpse of this lost oasis.

"Depending on the size of the reference, it's at least a kilometer wide." "Friend" pointed to a date palm tree not far away, and a faintly visible puddle of clear water: "But if this is man-made, maybe this space is not a curved surface, if it is a plane, maybe the space is a little larger." ”

"Is it possible that it is another country?" Kawago's prosthetic eyes were staring at the projection, and the eyeballs wouldn't move, but the collected images had already been transmitted to his brain.

"Of course we are skeptical, and that is one of the purposes of this mission." Huang Sanshao said: "If other countries had done this kind of thing, we should have considered fighting back." But the problem is that it has been almost twenty years since the mining of the country of Ousis, and there is no reason to do it now, and there is no reason to go to great lengths to build such an underground space. ”

"Suddenly I want to ask, did you continue to explore at that time?" Sun thought ruthlessly for a long time and asked.

This is a very critical question, if Huang Sanshao discovered this underground facility, then why didn't he continue to investigate?

"Nope." Huang Sanshao quickly shook his head, and at the same time showed another picture: "I was stopped by something." ”

I don't know if it was a human, an animal, or a machine, but Huang Sanshao didn't continue at that time.

Because in the photo, he just came out of the Lost Oasis, covered in scars, and has become a bloody man.

"The wound is not deep, it was caused by the wind blowing up the sand." Huang Sanshao had palpitations.

Wind?

That's four thousand meters underground.

At this moment, someone sent a message to Huang Sanshao, which lifted his spirits, and beckoned Sun Wuru and the four to follow.

Soon, they saw a familiar and sturdy figure on an elevator.

Du Shaozun was panting, and there was a huge gerbil hanging on his shoulder, which also looked sluggish.

"Probably figured it out, hey, why are you here?" He looked up, and the entourage behind him handed over a hard drive, which contained the information collected from the operation.

"Judging from the feedback from the babies." Du Shaozun touched the tired gerbil distressedly: "This area is at least 5,000 cubic meters, and it is still expanding. ”
