From black technology to super engineering

It is not accurate to say that it is a city.

It should be the ruins of a city.

It was built on a huge karst cave, and the erosion of the years has made it impossible to see the details of the building, only the outline of the building can be vaguely recognized.

The building adopts the method of combining steel and stone according to local conditions, and the floor height is generally about 20 meters. There is a clear street plan on the ground, piled with traces of collapsed and weathered building materials.

The ruins are empty and deep, stretching endlessly at a glance.

Even though they are separated by 2.6 million light years, they can still feel desolation and gusts of wind blowing towards them.

Everyone stared at the picture in silence for a long time.

After a while, Director Zhang sighed leisurely: "It seems that this place has been completely abandoned for longer than we thought."

Sheng Fei answered immediately: "If they also use concrete, it will take at least three to five thousand years of waste to weather like this."

"Then there must be nothing left, it might as well be a space ruin."

"Not necessarily, at least we can analyze their living habits from the perspective of architecture, and there are many gadgets that can actually be preserved for thousands of years..."

"Then we need to conduct a carpet search of the ruins, but these buildings are broken at first glance. How do you find them?"

"People always come up with solutions."

"Look, everyone, is that an underground pipeline?"

Amidst the chatter of the crowd, Ye Ming also called Ita in his mind and asked her to take over the drone and continue to explore.

Unlike other people's "lostness", Ye Ming has always maintained a calm and expectant mood.

Because logically, he decided that this should be the last shelter or place of survival of the Canglan Star civilization, at least one of them.

So...Think about it differently, what will an intelligent race do when they realize that their civilization is about to disappear?

If it were Ye Ming himself, besides saving at all costs, the more important thing might be to preserve as much as possible the essence of human civilization - knowledge, culture, and art. And let these be known by more civilizations as much as possible, and at the same time make them available to the next intelligent race as much as possible, so that the spirit and essence of civilization can be continued and inherited to the greatest extent.

And the premise of all this is preservation.

Ye Ming felt that those Canglan people who had created space cities and even visited the solar system thousands of years ago would probably have the same thoughts as themselves when their civilization came to an end.

As the drone advanced, the ruins became deeper and deeper, and those giant pipelines could be seen everywhere on the cave walls, and the pipeline network formed by the pipelines could still be vaguely recognized.

After a brief exchange, Ita simply followed the pipeline all the way to the depths of the ruins.

Gradually, a huge factory ruins appeared in front of everyone.

"If it were me, I would build a controllable fusion reactor in the underground city, and then make full use of the waste heat of the fusion reactor to control the temperature of the entire city." Ye Ming looked at the ruins and said softly: "So I guess this It's a fusion pile."

Director Zhang looked at him: "What about the source of food?"

Zhou Xiangnan immediately said, "Synthesis?"

"Well, synthesis is a way." Ye Ming nodded slightly, and let Ita continue to move forward: "At present, human's synthetic starch seems to be only short of the cost reduction of ribulose-1,5-bisphosphate carboxylase. Yes. Hmm...but we can't assume that the Canglan Star people need starch the same as us."

"Hey, Mr. Ye, it's not writing a thesis, so there's no need to be so rigorous." At this time, Sheng Fei laughed: "Since the ecological circle of the Canglan Star is highly consistent with the earth, and now they all tend to have the same origin, then the biological circles of the Canglan Star The food must be about the same... right Mo Gu?"

Mo Gu has been watching quietly from the side, and at this moment, he pursed his lips and smiled: "We boldly guessed that it is right, some people can't talk to death."

Ye Ming: "..."

Everyone is happy together.

Indeed, after entering the Canglan Star for detection, Ye Ming has always been conservative in his statements on slightly formal occasions, which fully demonstrates the rigor of a scientist-even if he wants to guess, he will add many attributives and environment.

Obviously, it's not that Ye Ming is timid, but that the more he faces big discoveries, the more he needs to be calm and not reckless.

"Everything should wait until the detection spacecraft arrives, and then make a comprehensive investigation of the food chain and ecosystem here before making a decision." Ye Ming paused after speaking: "But... since there are herbivores here, and plants Highly similar to plants on Earth, then...should be similar."

"They must also have a food processing factory, but not necessarily a starch production factory. Could it be other biological breeding? Don't forget, the Canglan Star people are very accomplished in the field of biotechnology."

During the speech, the drone had crossed the area identified by Ye Ming as the Great Transformation Power Plant, and came to another factory area with slightly lower buildings.

This factory area is densely covered with pipelines, and even the huge vehicles can be vaguely recognized on the ground.

Seeing this, Ye Ming's eyes gradually lit up.

Visible to the naked eye, the degree of weathering and corrosion here is slightly lower than that of the place from here.

That means, they run a little longer.

At this moment, Ita's voice suddenly sounded: "The drone has 30% power remaining, do you want to return?"

Ye Ming just thought for a while and made a decisive decision: "Continue to explore."

"receive."

"Go ahead, let's find the least weathered building."

"receive."

The drone continued to move forward. At this time, it had gradually reached the edge of the underground space, and from the perspective of weathering, it was indeed lower, but even so, all the buildings were dilapidated, completely devoid of any exploration value, or visible to the naked eye. the value of.

Ye Ming frowned deeply.

This dungeon is too big, and there is no light source. It is completely a dead city. It is too strenuous to explore with the illumination of the drone.

Of course, this is not the main thing. The main thing is that he didn't see any iconic buildings or signs-could the Canglan Star people lie flat at the last moment of civilization's demise?

Seeing Ye Ming's expression, Director Zhang knew that he was a little disappointed, and smiled slightly: "Mr. Ye, don't worry, we are only the first entrance. In such a big city, there must be more than one entrance. Let's do more next time." Check the battery again."

Ye Ming exhaled lightly, and after a while, he nodded slowly.

It seems that I am indeed a little anxious.

But at this moment, a flash of light suddenly appeared on the screen!

A piece of light that seemed to be shining on a bright mirror was suddenly reflected back, so that the lens was dazzled.

"what is that?"

"Looks like gold?"

"Golden Gate?"

Amidst the chatter of the crowd, the searchlight of the drone shined on the source of the reflection.

At the very edge of the city, a metal gate almost embedded in the cave wall shines with the unique light of gold.

Rows of words like tadpoles can be vaguely seen on the door.
