An atmosphere of frenzy spreads through the dark caverns......

Yu Yifeng was also in his veins, and he had a sense of impatience at the thought that there might be more relics of civilization below......

These big men are like taking medicine one by one, and they are still the legendary violent aphrodisiacs! When I was having a seizure, I suddenly saw a delicious girl......

One by one, they panted and blushed and dug frantically, and worked for two or three hours until they were exhausted and could no longer do it. Ｘ

Sure enough, the further down you go, the more you can dig up!

What are these strange things? Take it back first.

"Alright...... Okay guys, for now, let's go back first! ”

Yu Yifeng dug straight into the backache before finally speaking.

He looked at the people who were reluctant to return, and when he looked at the time, three hours had passed...... I guess the lizards outside are in a hurry.

The ruins of this civilization are so huge that they have only dug up the most ordinary house, and it is estimated that most of it is buried deep in the ground of this extinct volcano!

It is impossible for a few of them to dig it up...... It is equivalent to that after Yi Feng sobered up a little, he finally understood this.

The amount of work is too large, and a heavy excavator is necessary!

After hearing Yu Yifeng's order, everyone stood up very reluctantly, and they found a total of more than a dozen strange pieces of broken copper and iron. From the outside, I can barely make out a few pieces of circuit boards, and some metal that is too rusty, and I don't know what it is.

But the experts are unusually careful to pack them well, if they are real treasures!

Not only Yu Yifeng, but everyone was excited, curious, and doubtful in their hearts.

Now the answer to the "three nuts" has finally been revealed, left behind by a lost technological civilization, but people are caught in a much larger mystery.

What is the scientific and technological strength of this civilization? Why did they perish? And also...... Why is there nuclear radiation here?

Yu Yifeng frowned, all kinds of clues, logical reasoning, and the pictures flashed one by one.

Could it be that the demise of the race was due to the outbreak of a nuclear war within the race?

Practically unlikely...... Even if a nuclear war breaks out, it won't kill everyone in civilization, right?

There will always be a large number of individuals who have survived.

Did it degenerate into the most primitive lizard?

This is very unlikely......

There is another possibility, of course, that they were destroyed by an even more powerful interstellar civilization, and none of them survived. It is possible for an interstellar civilization to completely wipe out a low-level civilization.

And these indigenous lizards are an intelligent race born later, and they have nothing to do with this unknown civilization.

All in all, everything is an unsolved mystery until there is definitive evidence!

"Let's go, let's go out!"

Yu Yifeng finally glanced at the excavation site and took the lead and walked out.

The rest of the people could only reluctantly leave, with this bit of resentment on their faces, but they also knew that it was impossible to dig up the entire ruins with the hands of twenty people alone.

People were full of excitement and excitement, and even every cell in the body was trembling, eager to immediately dispatch a large army to excavate!

Many scientists are also eager to go back immediately and announce this really shocking, crazy news!

The seven lizards and others outside were a little impatient, and they were even a little afraid that these "spirit messengers" would also die inside......

Seeing Yu Yifeng and them walk out, they finally breathed a sigh of relief.

"Zhao Yao, a few of you will take the airship first and send this group of lizards back. The rest of us won't go back, we'll go straight back to the central base! Yu Yifeng said impatiently.

"Yes! Got it! ”

Zhao Yao and the others solemnly gave a military salute and sat on the airship with a few lizards who still didn't know the situation.

The rest is easy......

A bigger news than the Native Lizard has appeared in the Noah Society! Everyone felt like they had been hit on the head, and they were fluttering!

Knicks Star ...... There is actually a high-tech civilization hidden, or is it the extinct kind?!

The first instinct of the vast majority of people is ...... "pick up trash!" ”

It's time to pick up trash again!

Everything is difficult at the beginning, and after sorting out all the preliminary work, Yu Yifeng began to deal with many things. There are three most important tasks at the moment.

First, indigenous workforce development.

After careful discussion by many experts, the greatest value of these indigenous lizards still lies in their labor.

Of course, such a labor force is not physical, but mental.

According to the available data, the average IQ of these lizards is about 60-70, and of course there are individual individuals who can reach 100, which is the level of ordinary people.

If these indigenous lizards can really be educated and develop their intelligence, of course humans will have to use them. After all, the current human population is too small, and even if fertility is encouraged, it is unlikely to increase significantly in a short period of time.

So, a lot of the mechanical monitoring, mechanical management, and even the excavation of the ruins can actually be done by the lizards, if they are indeed up to the task......

According to scientists' estimates, there must be more indigenous villages on Nix, and a planet of this size has at least a million or even tens of millions of lizardmen!

Because of the influence of the times, their intelligence and cognition cannot jump to a very high level all at once, so they can only do some simple work.

But even relatively simple work can liberate a large number of human populations.

It is also because they are still in a state of ignorance, and the area of ideological management is relatively simple, and it is impossible to have a rebellion in the short term. A little heat or food can make them grateful to Dade.

This work is still at its earliest stage. The language must be mastered, and then the lizardfolk scattered around the globe will be recruited to select the most intelligent individuals before the next step of education can be carried out......

The second project is the construction of bases in the Arctic region!

Whenever Yu Yifeng sees all kinds of completion reports, his heart is still very comfortable, although this kind of logistics work is trivial, but it is also very important. After all, all industrial activities of human beings must be supported by minerals and energy. Now the mineral resources in the Noah are basically depleted, and the mineral resources in the Arctic base must be replenished.

The work is going very well, with massive buildings being built in patches, many minerals being detected from the Arctic, and vigorous excavation is underway......

Of course...... There is also a third big project, which is naturally an all-out exploration of the ruins of this civilization!

A large number of archaeological teams began to be re-recruited, and many robots began to mobilize to the area.

People want to know how many years it has been buried in the ground, its specific level of technology, and the main reasons for the extinction of civilization......

Civilization is extinct, such a thing is simply terrible!

People are desperate to find out why, what if such a disaster happens to them?

And, of course, the technology of this civilization, in fact, many people now have very mixed feelings.

If the technology of this civilization is higher than that of humans, then it is a good thing, and humans will have a more complete set of technology trees. Even if you are lower than humans, you can improve your scientific foundation.

But how did this civilization become extinct, maybe even because of science and technology?

Or ...... No matter how high the technology is, it will encounter some unknown terrorist events, will it be wiped out by interstellar civilizations?

This is not a high possibility, but it is possible.

Therefore, the mood of many experts is also extremely contradictory and complicated, and they have discussed one after another, but they can't explain why.

It's inconceivable that a fairly powerful civilization should become extinct like this.

And, experts speculate, there can't be only one such city! There must be more cities buried in unknown places, waiting for people to dig up!

The one in front of you is probably just a small city...... It is likely that it is only a county-level city equivalent to a human being, and there are higher provincial-level cities (provincial capitals), national-level cities (national capitals), and so on.

They're all buried in the ground!

However, it is still planned to start exploring the ruins of the city that have already been discovered...... There will definitely be more information in it.

It took more than half a month to prepare for this excavation......

A large number of excavators have long been transported by empty boats. A large scientific expedition team of about 2,000 people has also been formed, including various scientists, engineers, and so on.
