The ultrasonic fingerprint verification was completed instantly, and the glass box in Lu Yuan's hand protruded instantly, just presenting the USB flash drive.

Picking up the USB flash drive inside, Lu Yuan returned the same way, and as Sonny said, in the warehouse area of Area C, the USB flash drive was like an iron nail attracted by a magnet, and it was ready to move in his hand. The deeper you go into the warehouse, the more the USB flash drive moves, slowly moving in a certain direction at a speed visible to the naked eye.

"So, does it have anything to do with the thing found below?"

What was amazing was that as Lu Yuan stopped and held the USB flash drive with his backhand flatly, the wall in front of him suddenly became transparent, and soon, it became a wide transparent glass.

The lights were bright, the steel rails were everywhere, just outside the glass wall, the staggered steel rails were densely packed in the air, and the lights shining everywhere lit up everything around, but they couldn't penetrate the endless abyss below.

Yes, from the outside of a glass wall, the width reached five or six hundred meters, and the abyss with an unknown depth crossed in front of Lu Yuan, extending seven or eight hundred kilometers away, almost approaching the Australian continent.

"Hoo ......"

Lu Yuan's breathing was still short, and listening to Sonny's explanation was not as strong as the shock brought by what he saw with his own eyes.

The majestic and astonishing abyss in front of him was not the usual submarine canyon, and they knew where they were now, which was deeper than the bottom of the sea, piercing through the rocks of the seabed, hundreds of meters deep into the rock formations under the sea. That is to say, above the entire base, there is a deep layer of undersea rock formation, and then the seabed and the sea water at a depth of kilometers.

But Lu Yuan and Sonny never expected that in the depths of this undersea rock formation, there was a cavity-like abyss inside, the scale of which was so amazing, according to Sonny's early detection, even if Lu Yuan chose a second island. It is also possible to come across this abyss after digging through the bottom of the sea.

Human beings are far from being fully aware of the geological activities of the earth, and it can even be said that they are shallow, if it is just a cavity in the ground, which is just an unimaginable natural wonder, it will definitely not make Sonny urgently call Lu Yuan to rush back.

It is found that there seems to be a mysterious connection between this abyss and the USB flash drive, and it is getting closer to the abyss. The USB flash drive is like a marionette, and it will be attracted by itself out of thin air without any basis, which makes Sonny unable to ignore it, and immediately urgently notified Lu Yuan, who was far away in the country.

"Did you detect the depth?"

"THE DEEPEST PART IS 57,424.56M, THE AVERAGE DEPTH IS 54,287.45M, THE WIDEST POINT IS 785.48M, AND THE AVERAGE WIDTH IS 682

37M……”

The three-dimensional map of the holographic projection was displayed in front of Lu Yuan, and Lu Yuan's expression changed slightly, the depth of the abyss was actually 57 kilometers deep, the deepest Fichaz abyss on the earth. It is only 11034M deep, and the depth of this abyss is nearly 5 times the depth of the Fichaz Abyss!

"Really...... Earth scars. ”

Lu Yuan took a deep breath, suppressed the shock in his heart, and turned his head to look at Sonny: "Isn't there another anomaly you said?" ”

"Yes, sir, we discovered this ...... after a double scan of microwave radar and lidar."

The 3D map zooms in quickly. The specially marked inverted pyramid is clearly the base, and next to it. 1.3 kilometers away from the base, at a depth of 1,587 meters, in the air of this abyss, there are many dense linear objects, distributed in many places here.

"It's ......"

Lu Yuan frowned: "What?" ”

"Look, sir. Did you find anything? ”

The entire three-dimensional image began to change dozens of degrees, and then it was placed vertically in front of Lu Yuan, and suddenly his pupils couldn't help but constrict.

If you look at it from a flat surface, it's just a dense mass of threads, and you can't see anything abnormal. When you change the direction, when you look at it horizontally, the vertical line becomes an object with obvious rules in an instant.

"......" Lu Yuan was silent for a moment before he hesitated and said, "This is a bit like a positive six hundred cell body?" ”

"No, sir, it's not like it, and this is the most standard positive six hundred cells."

Sonny's electronic eye looked at the three-dimensional projection: "According to the detection, this object is composed of 600 regular tetrahedral cells, 1200 regular triangular faces, 720 edges, and 120 vertices, and it is an artificial building that is obviously built according to the Slegel three-dimensional projection, and the maximum error value at the joints will not exceed 1.2cm......"

"Artificial Building ......"

Lu Yuan sighed: "You mean to say that there is an artificial structure in a rock formation at a depth of several hundred meters under the thousand-meter-deep seabed of the South Pacific?" ”

"Yes, sir, it can never be a natural formation." Sonny nodded like a human, but he didn't understand the rhetorical question in Lu Yuan's tone.

"Okay."

Lu Yuan pinched his temples and felt an inexplicable pressure, what did he do? I didn't provoke anyone by digging a good hole, why did I dig out a weird artificial building? He doesn't seem to be archaeocating, is he?

"Okay, now the question is, what the hell is this? Why does it affect USB flash drives? ”

The USB flash drive is a product of modern electronics industry, and it has nothing to do with the objects in this abyss, why is there an unpredictable connection between the two?

"Sir, before you come back, I've had the drone go down to shoot and investigate. This is the image that was transferred back. ”

The most important thing here is drones, and drones are also much more convenient, which is suitable for reconnaissance work. On the screen, several drones can be seen rapidly descending in the abyss, and in a short time they are approaching the artificial structure of the countless threads.

"Is there air outside?" While watching the video, Lu Yuan asked.

"The air is very thin, the average temperature is -57 degrees Celsius, the air pressure is only 50Hpa, the oxygen content is 7%, the carbon dioxide concentration is 14.55%, and the rest of the toxic gases are not detected, but it is still not suitable for human life."

Hearing this, Lu Yuan was not surprised, but what is called unsuitable for human existence? This is not called unsuitable at all, but human beings are completely unable to survive, but I am afraid that within half a minute of going in, there will be hypoxia and carbon dioxide poisoning at the same time, and suddenly shock and die of hypoxic encephalopathy. Even if the air environment is normal, it is not suitable for human access like the ground, and -57 degrees Celsius can be compared to the edge of Antarctica.

After coming back to his senses, Lu Yuan continued to pay attention to the video taken by the drone, only to see that after approaching a depth of more than 1,500 meters, under the illumination of thousands of lumens of light, quite strange lines were displayed on the radar, which really caught Lu Yuan's eyes.

Although on the three-dimensional hologram, those are just some narrow lines, but when you look closer, you will find that those so-called lines are all tubes with a diameter of several meters. Thousands of lumens of bright light shone thousands of meters away, and this huge man-made structure was only slightly exposed, and its construction difficulty and scale were beyond the power of modern human technology.

"What kind of metal is that?"

The tube had a metallic luster under the light, and Lu Yuan asked with a frown.

"According to the atomic emission spectroscopy analysis, those tubes are titanium-containing steels containing 0.037% titanium."

"Titanium?"

With the volume of this man-made building, how much titanium steel is needed for this? Moreover, the high level of machining precision is quite surprising even from the perspective of the future world.

The drone continued to fly, quickly shuttling between the pipes in the body of the 600 cells, and faithfully recorded all the images taken, although the 600 cells have a large number of ridges, but with the huge volume of the building, in fact, the gap between the pipes is very large, not to mention the drone, even if it is an EDI fighter in it, it can also shuttle unimpeded.

"Wait, what's that......"

A flash of shadow, Lu Yuan, who had keen eyesight, did not let go, and immediately paused the video, and then magnified the shadow he had just observed.

Unfortunately, this is really just a fleeting shadow, and due to the problem of shooting angle, it is not possible to find more clear images.

Lu Yuan pondered for a moment, and continued to play the video, but when the whole video ended, he didn't find any useful clues. For example, the origin of this 6000-cell building? Who built it? Why are you here?

Of course, the most important point is, why is there an abnormality in the USB flash drive, and there is a strange connection there? (To be continued.) )

PS: I'll leave a chapter tonight, I have a cold, and I have a little low-grade fever.
