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

After picking up the USB drive inside, Lu Yuan returned the same way. As Sonny said, in the warehouse area of ​​Area C, the USB drive was like an iron nail attracted by a magnet, and was ready to move. The deeper it entered the warehouse, the more the U drive was moving, slowly moving in a certain direction at a speed visible to the naked eye.

"So, is it related to the thing found below?"

Surprisingly, as Lu Yuan stopped and held the USB flash drive in a calm manner, the wall in front of him suddenly became transparent, and soon it turned into a whole wide transparent glass.

The lights are brightly lit, and the steel rails are everywhere, just outside the glass wall. The interlaced steel rails are densely spread in the air. The lights shining everywhere illuminate everything around, but they can't penetrate the endless abyss below.

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

"call……"

Lu Yuan's breathing was still rapid, and after Sunny's explanation, it was not as strong as the shock brought by his own eyes.

The magnificent abyss in front of him was not the common undersea canyon. You should know that their current location is deeper than the seabed. It has penetrated the rocks under the sea and reached the rock formations of hundreds of meters deep. That is to say, above the entire base, there is a deep undersea rock layer, and then the seawater at a depth of 1,000 meters.

But Lu Yuan and Sonny never expected that there was a hollow-like abyss inside deep in the seabed rock layer, and its scale was so amazing. According to Sonny's early detection, even if Lu Yuan chose a second island, he might encounter this abyss after drilling through the seabed.

Humans are far from knowing the geological activities of the earth, and they can even be said to be shallow. If it were just a cavity inside the ground, it would be an unimaginable natural wonder, and it would definitely not cause Sonny to call Lu Yuan back urgently.

It is because of discovering that there seems to be a mysterious connection between this abyss and the U disk. It is getting closer to the abyss. The U disk is like a marionette, and will be attracted by itself without any basis. This is called "Sonny cannot ignore it." He immediately informed Lu Yuan, who is far away in China, immediately.

"Is the detection clear depth?"

"The deepest part is 57424.56M, the average depth is 54287.45M, the widest part is 785.48M, the average width is 682

37M…”

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

"It's really...a scar on the earth."

Lu Yuan took a deep breath, suppressed his inner shock, turned to look at Sunny: "Isn't there another abnormality you said?"

"Yes, sir, after double scanning detection of microwave radar and lidar, we discovered this..."

The three-dimensional map is rapidly enlarged, and the inverted pyramid specially marked is obviously the base. Next to the base, 1.3 kilometers away from the base, at a depth of 1,587 meters, in the abyss, there are many dense linear objects distributed in many places.

"This is……"

Lu Yuan frowned: "What?"

"Sir, please see, have you found anything?"

The entire three-dimensional image began to change by dozens of degrees, and then it was placed vertically in front of Lu Yuan, and his pupils suddenly shrank.

If we look at it from a plane, it is just a dense mass of linear objects, and there is no abnormality. When we change direction and look at it from the horizontal direction, the vertical linear objects will instantly become objects with obvious rules.

"..." Lu Yuan was silent for a while before hesitating: "This is a bit like a regular six hundred cell body?"

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

Sonny's electronic eye looked at the three-dimensional projection: "According to the detection, this object consists of 600 tetrahedral cells, 1,200 regular triangular surfaces, 720 edges, and 120 vertices. It is an artificial building with an obviously built according to the Sleiger three-dimensional projection, and the maximum error value at the joint will not exceed 1.2cm..."

“Artificial buildings…”

Lu Yuan sighed: "What do you mean is that there are artificial buildings in the rock formations of hundreds of meters deep under the seabed in the South Pacific?"

"Yes, sir, this could never be formed naturally." Sonny nodded as he learned from humans, but did not understand the rhetorical question in Lu Yuan's tone.

"All right."

Lu Yuan pinched his temple and felt a sense of inexplicable pressure. What did he do? He dug a hole but didn't mess with anyone. Why did he dig out a strange artificial building? He didn't seem to be in archaeology?

"Okay, the question now is what exactly is this? Why does it have an impact on the USB drive?"

USB flash drives are products of modern electronics industry manufacturing and are completely irrelevant to objects in this abyss. Why does the two have an unpredictable connection?

"Sir, before you come back, I had the drone go down to take a photo and explore. This is the image transmitted."

The most inexpensive thing here is drones, and drones are much more convenient, and they are suitable for exploration. You can see that on the picture, several drones quickly descended in the abyss, and soon approached the countless artificial buildings with lines.

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

"The air is very thin, with an average temperature of -57 degrees Celsius, an air pressure of only 50Hpa, an oxygen content of 7%, and a carbon dioxide concentration of 14.55%. No other toxic gases were detected, but they are still not suitable for human survival."

Lu Yuan was not surprised when he heard this sentence, but what does it mean to be inappropriate for human survival? This is not called inappropriate at all, but humans cannot survive at all. They are afraid that they will be deficient in oxygen and be poisoned by carbon dioxide, and they will die of shock from hypoxic encephalopathy. Even if the air environment is normal, it is not suitable for humans to enter, as if it were the ground. -57 degrees Celsius can be comparable to the edge of Antarctica. Without protective and warm equipment, they will be frozen to death.

After coming back to his senses, Lu Yuan continued to pay attention to the video taken by the drone. He saw that after approaching a depth of more than 1,500 meters, the lights with thousands of lumen intensity were illuminated, which really caught Lu Yuan's eyes.

Although it looks like those in a three-dimensional hologram, when you get closer to the past, you will find that the so-called linear objects are all tubes with a diameter of several meters thick. Thousands of lumens of strong light shone thousands of meters away, this huge artificial building only exposed a little. The difficulty of its construction and its magnificent scale are by no means possible by modern human technology.

"What metal is that?"

The tubular object had a metallic luster under the light, Lu Yuan asked frowned.

"Based on atomic emission spectrum analysis, those tubing are titanium-containing steels containing 0.037% titanium."

"Titanium steel?"

With the volume of this artificial building, how much titanium steel should be used? And the processing precision is so high, even from the perspective of the future world, it is quite surprising.

The drone continued to fly, and quickly shuttled through the pipes inside the six hundred cells, faithfully recording all the images captured. Although the six hundred cells have 720 numerous edges, with the huge volume of the building, the gap between the pipes is actually very large. Not to mention the drone, even the EDI fighter can shuttle unimpededly inside.

"Wait, what is that..."

The flash of shadows, the keen eyes, did not let go of the video, immediately paused the video, and then magnified the shadow I just observed.

Unfortunately, this is indeed just a fleeting shadow. Due to the shooting angle, more clear images cannot be found.

Lu Yuan pondered for a while and continued to play the video, but after the entire video was completed, no useful clues were found. For example, the origin of this six hundred-cell building? Who built it? Why was it here?
Chapter completed!
