Before the tea in the conference room had cooled down, a group of people sat back again.
However, this was not a professional meeting, so Zhou Xiangnan and others also came after hearing the news.
Everyone pulled down the curtains and cleared the table in a hurry, and then Ye Ming asked Aita to start the 3D projection.
——Only the conference room has the latest holographic projection device, which can project a real 3D scene without blind spots.
The screen was projected, and an area of vegetation appeared in front of everyone's eyes.
The vegetation consists of various vines and ferns, which clearly grow around a huge square pit, forming a sharp contrast with the surrounding environment.
"I have been tracking a female tiger-like animal just now, and I accidentally tracked it here. Now the lower height is not obvious. When the height increases, under infrared detection, it can be clearly seen that this is a standard 5mx5
The entrance of the cave.”
As Zhou Xuchen explained, another drone flew over with a ground robot in the distance.
Logically speaking, it is most convenient to use a humanoid robot or a multi-legged multi-arm robot for such detection. However, not to mention that this place is nearly three kilometers away from the detector landing site, and those multi-functional robots cannot be hoisted by drones.
, you can only come here on foot, but there are three kilometers of primeval jungle in between...
Fortunately, the detector carries a variety of ground robots, especially this small crawler robot, which can just be hoisted by a drone.
After the drone selected a slightly exposed patch of ground and lowered the crawler robot, Aita turned on the microwave radar of the ground robot.
Under microwave radar, the square dimensions of the hole are clearer, and it is obvious that the hole is vertical.
A common common sense is that although there are various uncanny geometric miracles in nature - such as honeycombs, most of them are creations of organisms at the microscopic level, rather than engineering standards on this large scale.
Therefore, when Aita accurately modeled the cave entrance based on infrared and radar data and determined that the entrance had a strong magnetic response, everyone was speechless for a long time.
…
"The mound of soil at the entrance of the hole has an obvious red color, which must be traces of oxidation of steel products."
"Judging from the magnetic field response, the vertical cave wall should also be a steel structure - Aita, prepare to fly in and take a look."
"OK."
"If your guess is correct, this should be the entrance and exit of an elevator." Ye Ming crossed his arms with a serious expression. At this time, he turned to Zhou Xiangnan: "Old Zhou, what do you think?"
Although Zhou Xiangnan and Sheng Fei are both engaged in materials, Sheng Fei prefers polymer materials, while Zhou Xiangnan has done research on alloys, so he needs to know more theoretically.
Of course, anyone with a bit of common sense should be able to tell that this is a man-made steel structure.
"Well, an elevator, or a vent? But looking at the degree of oxidation with the naked eye, it should be at least several thousand years old..."
"Almost." Ye Ming nodded, pondered for a moment and then continued: "If the age can be determined next, then the history of the Blue Star civilization can be connected."
At this time Director Zhang interrupted: "Escape, right?"
Ye Ming hummed.
The escape theory is the reason why humans built such a large space city for the Blue Star civilization - according to current detection, the city is enough to accommodate tens of millions of people, and has various complete living areas, material circulation and production measures -
A hypothesis established.
After all, according to common sense, living on the ground is always more comfortable than living in the air.
For example, when humans build space cities, they are mainly for scientific research and business development. If you really want to move all humans there...
That's really meaningless.
Unless I can no longer stay on the ground.
And the space city built by Blue Star is obviously not the same as the earth.
Maybe they can't stay any longer.
——Not to mention anything else, let’s just say that the thick polar glaciers are enough for them to drink a pot. In the sky, the Blue Star is a blue-white planet, and the blue is only part of the ocean located at the equator.
The white color represents large areas covered by ice and snow.
In other words, the only place truly suitable for "humanoid" creatures to survive is around the equator.
But when did they escape, when was the space city built, and whether they escaped from space or from the ground... everyone is a little unsure.
Because the space is not peaceful either - the satellites have dried up and broken into pieces, forming a star ring. You think... how unlucky is this blue star?
But now, as long as we can compare the earliest dates of the two ruins, we can determine the era of the Blue Star civilization.
…
The drone descended slowly, the lights were turned on, the cave wall was clearly visible, and the traces of steel became thicker. Everyone also stopped chatting, and their hearts gradually accelerated as the drone descended.
From the outside, there is no one here anymore.
But everyone still has a bit of luck in their hearts.
Because the destruction of such a large space city certainly did not happen instantly—or, in other words, after it was destroyed, everyone certainly did not die instantly.
Then, according to common sense, someone will always escape.
Where to escape?
Of course, escape to the ground!
Therefore, in previous explorations, the detector has been receiving and analyzing signals from the ground. Until the detector lands, it also takes the search for electromagnetic signals from the ground as its first goal.
It's a pity that I didn't receive it.
It's like it was completely wiped out.
Of course, there is another possibility that the civilization of the Blue Stars was destroyed, and then the civilization regressed to the primitive period - which is why the probe chose to land in this jungle.
But because the detector can really do too little, we can only fly some drones, and then collect biological data on the spot, and if we want to find people... we can only try our luck.
But it's different now.
Now traces of the artificial dungeon have been found...
That means that this place may be the last refuge of the Blue Star civilization!
Based on the technological power they have shown, unless they are completely wiped out by the enemy, there must be no problem in surviving and surviving for a long time.
And completely kill them all...
Frankly speaking, the human brain really cannot think of any reason for one star civilization to wipe out another civilization and kill it until no one is left alive.
Unless it's a zombie that likes to eat human brains and won't be able to walk if it sees it.
Therefore... even if there seems to be no sign of any living creatures here, it should be the last refuge.
While waiting in silence, the searchlight in front of me suddenly dimmed.
It was as if I was suddenly illuminated into boundless darkness and emptiness.
Everyone held their breath for a moment.
"Stop modeling and share live footage."
"OK."
Following Aita's voice, there was a flash of light in the air, and Aita directly projected an ultra-high-definition camera image on the screen.
Wherever the searchlight's light reaches, a looming giant underground city appears in front of everyone's eyes.
