From black technology to super engineering

Before the tea in the conference room had cooled completely, a group of people sat back again.

It's just that this time it's not a professional meeting, so Zhou Xiangnan and others also came after hearing the news.

Everyone hurriedly pulled down the curtains and cleared the table, and then Ye Ming ordered Aita to start the 3D projection.

——Only the conference room has the latest holographic projection device, which can project a real 3D scene without dead ends.

The screen was projected, and a vegetation area appeared in front of everyone.

The vegetation consists of a variety of vines and ferns that visibly grow around a large square pit, in stark contrast to the surrounding environment.

"I have been tracking a female tiger-like animal just now, and I accidentally tracked it here. Now the height is not obvious, but the height is increased. Under the infrared detection, it can be clearly seen that this is a standard 5mX5 of the hole."

Following Zhou Xuchen's explanation, another drone flew over with a ground robot in the distance.

It stands to reason that for such a detection, it is most convenient to use a humanoid robot, or a multi-legged multi-arm robot. But this place is close to three kilometers away from the landing point of the probe. Not to mention, those multifunctional robots cannot be hoisted by drones, so they can only come here on foot, but there is a three-kilometer virgin jungle in the middle...

Fortunately, the probe brought a variety of ground robots, especially this small tracked robot, which can just be hoisted by the drone.

After the drone chose a slightly bare ground and put the crawler robot down, Aita turned on the microwave radar of the ground robot.

Under the microwave radar, the square size of the hole is clearer, and it is obvious that the hole is vertical.

A common sense is that although there are all kinds of geometric miracles in nature—such as honeycombs—they are mostly created by organisms at the microscopic level, rather than engineering standards on such a large scale.

Therefore, when Aita accurately modeled the hole based on infrared and radar data, and then confirmed that the entrance had a strong magnetic response, everyone was speechless for a long time.

...

"The soil mound at the entrance of the cave is obviously red, 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, I'm going to fly in and take a look."

"OK."

"If the guess is correct, this should be the entrance and exit of the elevator." Ye Ming folded his arms with a serious expression. At this moment, he turned his head to Zhou Xiangnan: "Old Zhou, what's your opinion?"

Although Zhou Xiangnan is engaged in materials like Sheng Fei, Sheng Fei prefers polymer materials, while Zhou Xiangnan has done the subject of alloys, so he needs to know a little more theoretically.

Of course, anyone with a little common sense should be able to tell that this is a man-made steel structure.

"Well, the lift, or the air vent? But judging by 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 Canglan Star civilization can be linked together."

At this moment, Director Zhang interjected, "Is it right to escape?"

Ye Ming hummed.

Escape said that humans built such a large space city for the Canglan Star civilization—according to current detection, the city is enough to accommodate tens of millions of people, and has a variety of complete living areas, material cycles, and production measures— A hypothesis was 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. You really want to transfer all humans to it...

That's really meaningless.

Unless you can't stay on the ground anymore.

And the big space city built by Canglan Star is obviously different from the earth.

They may not be able to stay any longer.

——Not to mention anything else, just say that the thick polar glaciers are enough for them to drink a pot——In the sky, the Canglan Star is a blue and white planet, and the blue is only part of the ocean at the equator. The white is a large snow-covered area.

In other words, the only place that is truly suitable for the survival of "humanoid" creatures is the equator.

But when did they escape, and when the space city was built, whether they escaped from space or from the ground... Everyone is a little uncertain.

Because the space is not very flat - the satellites were all shattered, and then formed a star ring, you say... How unlucky is this blue star?

But now as long as the earliest time of the two ruins can be compared, the Canglan Star civilization can be broken down.

...

The drone descended slowly, the lights were turned on, the cave wall was clearly visible, and the traces of steel became more and more dense. Everyone also stopped chatting, and their hearts gradually accelerated as the drone descended.

On the surface, there is no one here.

But there is still a little luck in everyone's heart.

Because the destruction of such a large space city certainly did not happen instantly—or in other words, after being destroyed, it certainly did not happen instantly that everyone died.

Then, according to common sense, someone will always escape.

where to escape?

Of course it is to escape to the ground!

Therefore, in previous explorations, the probe has been receiving and analyzing signals from the ground until the probe lands, and it also takes the search for electromagnetic signals on the ground as its first goal.

It's just a pity that I didn't receive it.

It's like it's all gone.

Of course, there is another possibility that the Canglan Star civilization was destroyed, and then the civilization regressed to the primitive period-this is why the probe landed in this jungle.

It's just that the probe can do too little, so I can only fly some drones, and then collect biological data on the spot, looking for someone... that can only be pure luck.

But it's different now.

Now I have found traces of the artificial dungeon...

That means that this place may be the last shelter of the Canglan Star civilization!

According to their technological strength, unless they are completely wiped out by the enemy, they can survive and survive for a long time, then there must be no problem.

And completely kill...

Frankly speaking, the human brain really can't think of a reason for one star civilization to wipe out another civilization, killing every dog ​​and dog.

Unless it's a zombie, who likes to eat human brains, he can't walk when he sees it.

So... Even if there doesn't seem to be any sign of living things here, it should be the last refuge.

While waiting in silence, the searchlight in front of him suddenly dimmed.

It was as if suddenly shining into the boundless darkness and void.

Everyone held their breath for an instant.

"Stop modeling and share instant footage."

"OK."

Following Aita's voice, there was a flicker in the air, and Aita directly projected an ultra-high-definition camera image on the screen.

Wherever the light of the searchlight reaches, a huge dungeon looming in front of everyone's eyes.

(Let me think about their words.)
