The men continued to walk in for half an hour, and everyone was alert, moving carefully and softly.

Here the black hole, the quiet, seemingly nothing, only some strange fungi and geothermal plants tenaciously grow, but the density is much smaller than the caves in the b11 area.

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

Even ... even the traces of animals are very few, and occasionally only a few strange-looking animals emerge, which should be the "monster" in the mouth of the lizard.

They look highly aggressive, but they are all malnourished, strong and dry, and pose no threat to humanity.

"At present, we are about 120 meters away from the surface and the ambient temperature is 4 degrees Celsius.Nuclear radiation here has exceeded the dose that the average person can afford, and in such a place for a period of time, it is easy to get radiation sickness.”

A scientist who examined the detection instrument and said seriously, "I think perhaps the monster that indigenous lizards say is the mutated species that come from radiation."

“What they call a curse is nuclear radiation.That’s why Illness, or infertility.”

The twilight can't help but nod his head.

Indigenous people usually classify things that don’t understand as ghosts, but humans don’t.Humans are always able to find out the truth about these phenomena.

The truth seems to be so...

Where does this high level of nuclear radiation come from?

Was there a nuclear war here?Has there ever been a high-level civilization here, or was it... once a star battlefield?

All kinds of thoughts came to Yi Feng's mind, and everything seemed so confusing.

“Captain, look here!”

At this moment, Zhao Yao’s eyes lit up behind him.

He stepped cautiously forward, dug a rusty iron rod from the pit, and slowly handed it to Yi Feng's hand.

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

This iron bar is like a steel bar in the house!Yes, it is not other things, it is an ordinary steel bar, and it is impossible for nature to appear in such a thing.

However, it was too rusty, and it was completely cut off under a touch, and it could not see the original situation at all.

Yu Yifeng earthquake, the heart jumped, he couldn't help but ask: "Can you detect the specific material texture and age?"

Another scientist took the iron bar, carefully identified it, and shook his head in difficulty: "The rust is too strong, basically blended with the surrounding environment, and is difficult to identify..."

"But when you get back to the base, you have enough equipment to try it."

Everyone is excited and commotion because of the appearance of this iron bar, which means that they have found the right place, there must be more things here!

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

Be silent, indicating that everyone is quiet.

He crouched down and carefully examined the ground, all of which were dirt and gravel, and there was no unusual place.

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

“Come on, let’s all dig together!”

After hearing the call of Yi Feng, more than a dozen people squatted down immediately, and did not say much, digging directly to the ground.

The rest carried guns and were on alert.

The power armor itself is a high-strength metal and has a certain excavation function.Coupled with this piece of soil is relatively soft, there is not much stone, its digging speed is very fast, ten minutes later the results were dug.

It's a...house!

A steel and cement house that has fallen in half!You can see the steel bars buried in the walls.

It is not known how many years it has been buried here, and what has been rotten inside, but it can still identify the traces of the house...

Walls... and the scraps of furniture!

“No, it can’t be a relic of an interstellar civilization!”It is an ordinary house, an ordinary residential house... there has been a civilization here!”

A scientist spoke obtutely.He had a trembling in his mouth, not only with excitement, but with a tinge of fear and with a tinge of fanaticism.This kind of contradictory and crazy mood is indescribable.

There was even a city here!It’s just the most ordinary house, yes, it must be just an ordinary house!”

But what about civilization?What about the city?

Why did civilization disappear?

Are the lizards the descendants of this unknown civilization?Why do they degenerate to such a point?

It's impossible!

Will civilization be able to retreat?

With great shock in their hearts, they began another excavation.Then more strange things came out.

They dug down a meter or two deep and dug out something similar to a cement road.However, with the passage of time, there are scattered walls and ruins everywhere, and even integrated with the surrounding environment, can only barely identify it.

Next up is a road!

This is truly a roadside house.

It’s been too long, too long...

It has almost erased the traces of civilization!

Civilization, in front of the ancient universe, is a drop in the ocean.

Yu Yifeng became more and more frightened, not only the incomparable excitement, he felt that his heart was also being held down by something, and this feeling of contradiction made him almost breathless.

“Look, come and see!”One researcher dug up a rotten metallic pump and couldn’t tell what it was.

“Is this... circuit board?”This is the circuit board!”Another man found a stone and cried wildly.Of course, the circuit board can not exist intact, it even integrated into the stone, into the same thing as fossils, from the stone can distinguish the circuit!

I took a cold breath at the end of the day.

Since it has circuit boards, it is certain that this civilization has developed into the era of electricity, even if science and technology are worse than human beings, it is not much worse.

Moreover, the personal computer of this unknown civilization may be quite popular!

You know... the area they excavated has a great probability, just a flat house!Yi Feng did not believe that he was so lucky, and he directly dug to the core of unknown civilization.You can dig any place to dig into a science and technology place.

“Can you determine the specific scientific content?”Yu Yifeng carefully looked at the circuit board embedded in the stone.

“Not yet.”Another science leader lamented: "The damage is too serious, we must take back the base to study carefully."But, from the scale of circuit integration, I’m sure its tech content is above the early 21st century...the remains of an unknown civilization!”

Speaking of which, the expert seems to have thought of something, became red-light, and fell into a state of fanaticism: “Even the simplest technology is good, at least it means complete!”The scientific and technological tree of our new human civilization is still developing too fast, because there are too few people, and there are a large number of faults...”

Even some ordinary technology on Earth is lost!Because our lunar database can't possibly include all the data on Earth!"

"And the emergence of this underground civilization can make up for the shortcomings of our ordinary technology ... no, maybe their technology is more advanced than us ... that would be better!" 」

As far as the current discovery is concerned, it is impossible to determine this unknown civilization and the new human civilization, which is stronger and which is weaker.

But according to the past indications, they have completely fallen on the Knicks!
