Didn't understand the function of this metal cylinder, Chen Shi took it first and continued to look for clues, but apart from that, he really couldn't find anything else, so he had to quit.

The 1214-b01 outside was still digging. Chen Shi glanced at him, walked slowly over, squatted while watching it digging, and fiddled with the metal cylinder on his hand.

After nearly ten minutes, 1214-b01 finally stopped moving. Among the excavated ruins, a metal box was found by it.

"Huh, what are you looking for in 1214-b01?"

It seems that 1214-b01 should be consistent with Chen Shi's guess. It is not the first time it has come here. This metal box may have been buried by itself.

Chen Shi's curiosity came up, and he leaned over his head and watched it open the box carefully, wanting to see what item it was for 1214-b01 to spend so much effort.

As a result, the items inside the box are actually very simple, is it a card?

A black card of I-sized I-size without any sign on the surface, so it is not surprising to be placed in the box.

So, 1214-b01 has spent such effort and not allowed Chen Shi to help him out, just for a card?

But Chen Shi immediately realized that this card could not be that simple. It might be an integrated circuit card with microelectronic chips embedded inside.

Then, the integrated circuit card that 1214-b01 has worked hard to dig out may have other functions.

1214-b01 threw the box away, carefully packed the black card, and then turned to look at Chen Shi.

Chen Shi pointed to the metal sphere in the distance and took out the metal cylinder he found. "I just found it there. Look, what's the use of this thing?"

1214-b01 is very familiar with the things here, and seeking its help is a way Chen Shi could think of.

1 However, the expression of 1214-b01 disappointed Chen Shi. He took the metal cylinder suspiciously and looked around, but he didn't seem to understand the purpose of this thing.

Chen Shi said disappointedly, "Do you understand, don't you?"

But the next moment, Chen Shi lay down in a groove, and the armor of his two fingers pressed the top of the upper and lower ends of the cylinder at the same time. In an instant, the cylinder immediately changed, producing a slight light blue light.

Is it necessary to press the upper and lower ends at the same time?

He could only hold the metal cylinder in his left hand, so he didn't unconsciously find this method. Moreover, even if both hands are intact and luck is a bit unlucky, he may not be able to explore this method in a few days.

1214-b01 activated the metal cylinder. After a few doubts, it gently placed the cylinder vertically on the flat ground.

The metal cylinder left the palm of 1214-b01's palm, and the surface immediately took six directions, and metal sheets fell one after another. In Chen Shi's stunned, rays of light shot out from each part of the cylinder, forming a series of 3D images in the dusty air.

1214-b01 turned off the lights on his glasses almost immediately. Chen Shi reacted and followed them off. Without the interference of two strong lights, the 3D image projected in the air was indeed more clearly visible.

He opened his eyes wide and stared blankly, and saw the image in the air changing. A schematic diagram of an inverted cone structure slowly unfolded, more than three meters high, occupying the height of the top of the cavity in the ruins. In such a huge diagram, the blue light outlined the marks of each layer, densely packed and uncounted for a moment.

At first glance, I didn't know what this inverted cone three-dimensional structure meant, but gradually, Chen Shi stared at the position of one of the layers of flashing red light.

It is in the middle of the inverted cone shape, and there are more than a hundred layers below. Each layer has only one division on the shadow of the picture. This means that the upper layer of the red light may exceed the number of layers below. It is only because the shadow of the picture has been projected to the "ceiling", which is blocked by the "ceiling" and cannot be fully expanded.

Chen Shi couldn't help but step forward, as if these 3D projections were like real objects. He couldn't help but stretch out his left finger and gently touched the place where the red light was shining.

With this touch, the entire 3D projection image shadow immediately unfolded and changed, quickly rotated and enlarged, and the inverted cone structure disappeared directly, turning instead of a whole layer of flat 3D images appearing in front of Chen Shi.

Although there is no extra color and only blue light, Chen Shi still sees it, just like a sketch outlined by a pencil. Although there is only one color, it does not prevent the depiction of real objects.

"That's... a metal city? This is a cement boardwalk with tall buildings? That's a gray city?"

Chen Shi couldn't hide the shock on his face. He didn't understand yet. This was simply a 3D projection map!

He was immediately excited and actually found a map by him, which was still in 3D. If there was such a map, he could figure out where he was.

Chen Shi looked left and right, followed the route and saw the sea when he came, the towering dam, the metal city, and other incomprehensible areas.

He just needs to click on a certain place, and that place will quickly enlarge until it is almost 110. Because of this, Chen Shi realized the hugeness of this map. The gray city he saw before was thought to be vast and boundless, but it turned out to be a very small part on the map. If compared, it would be equivalent to comparing the total area of ​​three or four Guangdong provinces with a provincial capital.

In this way, even the metal city is so small on this map.

Chen Shi was frightened and a cold sweat was blowing behind him. He inevitably thought that the area of ​​this layer was so terrifying, and on the overall inverted cone 3D map, this was just one layer.

There are more than a hundred layers below where he is located. I don’t know how many layers there are on it. Just seeing them, there are at least hundreds of layers.

Not to mention, the area is expanding on each floor.

So, where is he?

Still don't understand.

Instead, it made him even more moved. Can't he be moved? With such a huge area, people know how many alien creatures are created by artificial technology... It seems that none of the people who have encountered it are friendly except for the hunchbacked ones.

"So, did that tower column actually connect the upper and lower levels? Where I am, it is in an inverted cone-shaped building? But what are the two moons I see on the sea? And there is also the sun..."

Isn't it true that the moon and the sun are fake?

Chen Shi was puzzled and finally sighed. It was not that he couldn't figure it out, but that the gap in technology levels was like letting a monkey figure out the operating principles of human cars, and he couldn't figure out how an iron box could act spontaneously.

He doesn't have to continue to torture his poor brain. At this time, he should be happy. With this map, it means that he has obtained important clues and has important assistance to the next trend.
