Beneath Deep Space

The group of people continued to walk inside for half an hour, everyone looking around cautiously and moving carefully.

It is dark and quiet here, and there seems to be nothing there. There are only some strange fungi and geothermal energy plants growing tenaciously, but the density is much smaller than the caves in Area B11.

If the last bit of geothermal heat disappears hundreds or thousands of years later, they will wither and die.

Even... there are very few traces of animals. Occasionally, only a few strange-looking animals pop out. They should be the "monsters" in the mouth of the lizard.

They appear to be highly aggressive, but they are malnourished, strong on the outside but weak on the outside, and do not pose the slightest threat to humans.

"We are currently about 120 meters deep from the surface, and the ambient temperature is 4 degrees Celsius. The nuclear radiation here has exceeded the dose that ordinary people can bear. If you stay in this place for a period of time, it is easy to get radiation sickness."

A scientist checked the detection equipment and said seriously: "I think maybe the monsters mentioned by the indigenous lizards are mutant species produced after being exposed to nuclear radiation."

"The curse they are talking about is probably nuclear radiation. That's why diseases or infertility occur..."

Yu Yifeng couldn't help but nodded.

Aboriginal people usually classify things they don't understand as gods and ghosts, but humans don't. Human beings can always find out the truth behind these phenomena.

It seems that this is the truth...

But where does such high nuclear radiation come from?

Could it be that a nuclear war had occurred here? Has an advanced civilization ever appeared here, or... was this once an interstellar battlefield?

Various thoughts emerged in Yu Yifeng's mind, and everything seemed so confusing.

"Captain, look here!"

At this moment, Zhao Yao's eyes lit up as he was following behind him.

He stepped forward carefully, dug out a rusty and shapeless iron rod from the pit, and then slowly handed it to Yu Yifeng's hand.

Yu Yifeng frowned and took the iron rod and looked at it carefully.

This iron rod... actually looks a bit like the steel bars in the house! Yes, it's nothing else, just an ordinary steel bar. It's impossible for such a thing to appear in nature.

However, it was so rusty that it broke off when touched, making it impossible to see the original condition.

Yu Yifeng was shocked and his heart was beating wildly. He couldn't help but ask: "Can you detect the specific material texture and age?"

Another scientist took the iron rod, examined it carefully, and shook his head in embarrassment: "The rust is so strong that it basically blends in with the surrounding environment, making it difficult to identify..."

"But when we get back to the base, we have enough instruments, so we can give it a try."

Everyone was excited and commotion because of the appearance of this iron rod, which meant that they had found the right place, and there must be more things here!

It is impossible for a rusty steel bar to appear for no reason...

Yu Yifeng remained silent and motioned for everyone to be quiet.

He squatted down and carefully inspected the ground. It was all soil and gravel, and there was nothing unusual about it.

He suddenly touched the wet soil with his hand, and felt an inexplicable intuition in his heart.

"Come on, let's dig together!"

After hearing Yu Yifeng's call, more than a dozen people immediately squatted down and dug directly into the ground without saying anything.

The rest were holding guns and responsible for guarding the surrounding area.

Power armor itself is made of high-strength metal and has certain digging capabilities. In addition, the soil was relatively soft and there were no big rocks, so the digging speed was very fast, and the results were dug out in just ten minutes.

A... house!

A half-collapsed reinforced concrete house! The steel bars buried in the walls are vaguely visible.

I don’t know how many years it has been buried here. The contents inside have long been rotten, but traces of the house can still be identified...

Walls...and pieces of furniture!

"No, it can't be the remains of an interstellar civilization! It's an ordinary house, an ordinary residential building... There was a civilization here!"

A scientist suddenly spoke up. There was a tremor in his mouth, not only excitement, but also a hint of fear and a hint of enthusiasm. This contradictory and crazy feeling is simply indescribable.

"There was even a city here! This is just the most ordinary house, yes, it must be just an ordinary house!"

But what about civilization? What about cities?

Why did civilization disappear?

Are those lizards descendants of this unknown civilization? Why have they degraded to such an extent?

impossible!

Will civilization regress?

Everyone was filled with shock and started other digging. Then more strange things were unearthed.

They dug down a meter or two and dug out something similar to a cement road. However, as time goes by, ruins are everywhere, and they even blend in with the surrounding environment, and can only be barely recognized.

Down here, it turns out to be a road!

This is indeed an ordinary house on the side of the road

Time has passed too long, too long...

It’s been so long that the traces of civilization have almost been erased!

Civilization, in the face of the eternal universe, is nothing more than a drop in the ocean.

Yu Yifeng became more and more frightened. Not only was he extremely excited, he felt that something was suppressing his heart. This contradictory feeling made him almost breathless.

"...Look, look!" A researcher dug out another lump of metal that was so rotten and shapeless that it was impossible to tell what it was originally.

"This is... a circuit board? This is a circuit board!" Another person found a stone and shouted wildly. Of course, the circuit board could not exist intact. It was integrated into the stone and turned into something like a fossil. The circuit board can be distinguished from the stone! Yu Yifeng took a breath of cold air. Since there is a circuit board, it is certain that this civilization has developed to the era of electricity. Even if the technology is worse than that of humans, it is not much worse. Moreover, the personal computers of this unknown civilization may be quite popular! You know... the area they excavated has a high probability of being just an ordinary house! Yu Yifeng doesn't believe that his luck is so good. He can dig directly to the core of the unknown civilization with just a dig. He can dig up a technological place with just a dig. "Can you determine the specific technological content?" Yu Yifeng took a close look at the circuit board embedded in the stone. "Not yet." Another scientific team leader said regretfully: "The damage is too serious. We must take it back to the base for careful study. However, judging from the scale of circuit integration, I am sure that its technological content is above the early 21st century... the remains of an unknown civilization!"

As he spoke, the expert seemed to have thought of something, his face became red, and he fell into a state of enthusiasm: "Even the simplest technology is good, at least it means completeness! The technology tree of our new human civilization is still developing too fast. Because there are too few people, there are a lot of faults..."

"Even some ordinary technologies on Earth are lost! Because our lunar database cannot include all the information on Earth!"

"And the appearance of this underground civilization ruins can make up for the shortcomings of our ordinary technology... No, maybe their technology is more advanced than ours... That would be even better!"

Based on the current findings, it is not possible to determine which is stronger and which is weaker between this unknown civilization and the new human civilization...

But according to various signs in the past, they have completely fallen on Nix!
