After confirming the guess, Li Yu and the others did not have the slightest interest in the current aborigines occupied by these magpie nest doves, and the civilization developed by these current aborigines was of little value to Li Yu and them. Pen, fun, and www.biquge.info

The next thing Li Yu and the others have to do is to determine Li Yu's other guess, that is, whether there is an energy network on this planet, and one of Lin Wanbai's personal requests is to find the survivors of the real aborigines.

The existence of the energy network is very well confirmed, if you have the heart, you can easily detect it with the detection equipment of the space, this is a new module that Li Yu added to the space after discovering the energy network in the Purple Moon Kingdom.

Since he didn't expect that there would be an energy network on this planet, Li Yu didn't put the module function of detecting the energy network online, so he didn't discover the energy network at the first time.

After Li Yu had a guess, Xiao Wei turned on the detection module as soon as possible, which would have confirmed Li Yu's guess.

"Li Yu, the energy network on this planet is too rudimentary!" Lin Wanbai pointed to the energy network distribution map projected by Xiao Wei and said disappointedly.

"It's too simple, there are only three nodes, and there is no one to assist the node. Looking at the handwriting, it doesn't look like the handwriting of the energy network civilization on Felenon's side! Li Yu also didn't understand.

"Could it be done by another civilization? For example, if you steal the technology, you can't arrange the full set, so you can arrange the simplified one? Fang Qianmo put forward a conjecture.

"Well, we can't come to the right conclusion based on conjecture alone!" Li Yu decided not to waste his brainpower, but to start from the actual investigation.

The first thing to do is to decipher the language of the two aborigines, and from their historical records, it may be possible to draw conclusions. Secondly, Li Yu asked Xiao Wei to increase the detection of the entire galaxy and not let go of every anomaly.

For Li Yu today, they already have a wealth of experience in deciphering the language of aliens, and they don't even need Li Yu to go out in person, Xiao Wei has completed this work perfectly.

In order to distinguish between the two aboriginal races, Li Yu simply divided them into surface aborigines and underground aborigines.

After confirming that the entire galaxy did not have any monitoring facilities, Xiao Wei let the space's detection ability be fully exerted, so the underground natives soon appeared in front of Li Yu's eyes.

The underground natives are divided into three shelters, all of which go deeper than three kilometers into a huge underground space, with a total number of no more than one million. The three Vaults communicate with each other through a network of wired communications that may have been established at a time when civilization had not yet been changed, and the Vaults have all but sealed off access to the surface except for the necessary passages for survival.

Through the information gathered by sending robots to infiltrate the shelter, Li Yu and the others were surprised to find that although they may have been forced into the underground, the technological level of the underground natives is actually not low, and in general, it is about three hundred years more advanced than the earth that has not been changed by Li Yu's laboratory.

It can be seen that the underground natives have already entered the interstellar age before the entire planet changes, as evidenced by the information obtained by the robot secretly from the computer in the shelter.

The direction of the development of computers for the underground natives is different from that of the earth, and they are going through biotechnology. Almost every member of the underground aborigines has a biological computer implanted in their bodies, and the performance of the biological computer used for administrative management and scientific research is comparable to the performance of the first generation of optical quantum computers researched by Li Yu.

So, relatively speaking, it is the underground natives who have made breakthroughs in research, and they have preserved a large amount of raw material about the changes in the planet. On the contrary, the way for surface people to preserve civilization materials is still paper made of a special plant, and the places where the materials are stored are also scattered, so the speed of collecting materials is relatively slow.

From the materials obtained from the biological computers that secretly invaded the underground natives, Li Yu and the others pieced together some fragments of what happened hundreds of years ago.

That's right, it's a fragment rather than a complete story, because the underground natives are also confused about what happened at the beginning.

In the accounts of the underground natives, that day was supposed to be an ordinary day. Although the three superpowers are each claiming ownership of a certain celestial body in space and spraying the other two countries, they have always loved and killed each other, and the peoples of the world have become accustomed to it.

Just when everyone thought that this day would pass like this again, mysterious forces came from the depths of the starry sky, first all the various probes that occupied almost the entire galaxy were lost, and then the ships that were constantly sailing in the galaxy began to lose contact.

The high-level officials of the three countries on the planet, from various fragmentary information transmitted back, speculated that there was a long-rumored alien invasion, and it was an irresistible kind.

In desperation, the three nations had no choice but to urgently evacuate their elites to a top-secret shelter established during the planetary era, hoping to leave the seeds for civilization.

But this mysterious force came too quickly, and the countries only came and carried out a small transfer of personnel, and this force descended on the native planet, and at this time, all the colonies, space stations, and observatories in space have all lost contact.

In desperation, the higher-ups had to hastily end the rescue operation, and even if they were already in the shelter, no one had hope.

Because through various detectors scattered around the world, the members of the Vault, watching the achievements of civilization they have developed for nearly 10,000 years, were destroyed by inexplicable forces.

In less than a day, all traces of civilization on the surface of the planet had been wiped out, and just when all the members of the Vault thought it would be their turn next, the attack stopped.

After the attack, the planet is devastated, and there are hardly any survivors on the surface of the entire planet, this is definitely a genocidal attack, and the entire civilization can be said to be extinct, because according to statistics, the members of the three shelters are less than half a million in total.

Of course, with such a big planet and three big countries, it is impossible to have only three shelters, but as soon as the incident happened suddenly, everyone did not expect the attack of the inexplicable force to come so quickly, and it only took less than two days from the beginning of the attack to the end of the attack.

Second, most of the other evacuation bases are in disrepair, almost all of them are simple bomb shelters, and even if they are stronger, they have not escaped attack.

After the attack, the three refuge bases only rescued less than 200,000 from the outside.

The destruction of civilization was just the beginning, and the survivors found that the entire planet suddenly changed to become strange to them.

Suddenly, like a night of spring breeze, thousands of trees and pear blossoms bloom. It is not only the traces of civilization that have been destroyed by inexplicable forces, but also entire ecosystems. But under the action of inexplicable forces, like a movie fast-forwarding, the entire planet was restored to its original ecology overnight.

Moreover, there are many plants, no one knows, and then the whole planet suddenly has strong geological activities, these geological activities did not last long, and then the whole planet is slowly filled with a strange energy, energy that has never been seen before.

The Vault is actually called the Doom Base, which was built for an extinction event to occur one day, so it resisted geological activities, and the Doomsday Base also contains the achievements of the civilizations of the three countries, but unfortunately there are too few surviving members to meet the requirements of civilization revival at all.

The number of members in the Vault has not grown significantly since then.

After carefully observing for a long time, the members of the Vault felt that there was no danger on the surface and were ready to leave the Vault to restore civilization, but they suddenly found that an unknown intelligent creature suddenly appeared on the surface.

No wonder the survivors were timid, because they found that these intelligent beings who suddenly appeared were able to grasp and use these unknown energies! The attack method of these unknown energies is extremely similar to the original attack force!

Frightened survivors will never leave the vault until they have studied the unknown energy. And then hundreds of years passed.
