After confirming the speculation, Li Yu and the others were no longer interested in these indigenous peoples who occupied the magpie nest. The civilizations developed by these indigenous peoples were of no value to Li Yu and the others.

What Li Yu and the others have to do next is to determine Li Yu's other guess, whether there is an energy network on this planet, and Lin Wanbai's private request is to find survivors of the real aboriginal people.

The existence of the energy network is very confirmed. If you are interested, you can easily detect it with the detection equipment of the space number. This is a new module added to the space number after Li Yu discovered the energy network in the Ziyue Kingdom.

Since I had never thought that there would be an energy network on this planet, Li Yu did not launch the module function of the energy network detection, so he did not discover the energy network as soon as possible.

After Li Yu had a guess, Xiaowei turned on the detection module as soon as possible, and this has confirmed Li Yu's guess.

"Li Yu, the energy network on this planet is too simple!" 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 no one assists the nodes. Judging from the work, it's not like the work of arranging the energy network civilization of Fei Lenong!" Li Yu also didn't understand.

"Can it be done by another civilization? For example, if you learn the technology secretly and cannot arrange the full set, you will arrange the simplified ones?" Fang Qianmo put forward a guess.

"Okay, we can't get the correct conclusion by just guessing!" Li Yu decided not to waste his brain power, but to start from the actual investigation.

The first thing to do is to crack the language of the two indigenous peoples, and perhaps analyze the conclusions from their historical records. Secondly, Li Yu asked Xiao Wei to increase the detection efforts of the entire galaxy and not miss every anomaly point.

For Li Yu and the others today, they have already gained rich experience in cracking the language of aliens. They don’t even need Li Yu to do it themselves, so Xiao Wei completed this job perfectly.

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

After confirming that the entire galaxy did not have any surveillance facilities, Xiao Wei let the Space Detection Capabilities be fully utilized, so the underground indigenous people soon appeared in front of Li Yu and the others.

The underground indigenous people are divided into three shelters, all of which penetrate into the huge underground space above three kilometers underground, with a total number of no more than one million. Between these three shelters, they communicate with each other through wired communication networks that may have been established when civilizations have not been changed. In addition to the necessary survival channels, the shelter almost blocks the passages with the surface.

By sending robots to infiltrate the shelter, Li Yu and the others were surprised to find that although they might have been forced to enter the underground, the technological level of underground indigenous people is actually not low. Overall, it is about three hundred years ahead of the earth that has not been changed by Li Yu's laboratory.

It can be seen that before the entire planet changed, underground indigenous people had already entered the interstellar era. The information obtained by robots secretly from the computers of the shelter can prove it.

The development direction of computers of underground indigenous people is different from the earth, and they are in biotechnology. Almost every member of underground indigenous people has a biological computer implanted in the bodies of almost every member of underground indigenous people. The performance of biological computers used in administrative management and scientific research is comparable to that of the first generation of optical quantum computers studied by Li Yu.

Therefore, relatively speaking, the research breakthroughs were made by the underground indigenous peoples, who preserved a large amount of original data that had changed on the planet. On the contrary, the surface people used to preserve civilized data as paper made of a special plant, and the places where the data were preserved were also scattered, so the speed of collecting data was relatively slow.

From the information obtained from the biological computers of the underground invaders, 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 process, because the underground indigenous people are also confused about what happened.

In the records of the underground indigenous people, that day was originally an ordinary day. Although the three superpowers announced their ownership of a certain celestial body in space and sprayed the behavior of the other two countries so badly, they have always loved and killed each other, and people from all over the world have become accustomed to it.

Just when everyone thought that this day would pass again, mysterious power came from the depths of the starry sky. First, all the probes that occupied almost all the entire galaxy lost contact, and then the spacecraft sailing in the galaxy began to lose contact.

The senior executives of the three countries on the planet speculate that from various incomplete information sent back, the senior executives speculate that there was a long-standing alien invasion, and it was irresistible.

In despair, the three countries had to begin urgently evacuating their respective elites to the top-secret shelter established when they were still in the planetary age, hoping to leave seeds for civilization.

But this mysterious force came too quickly. All countries only had time to transfer their personnel for a small amount of time. This force descended onto the local planet. At this time, all colonies, space stations and observatories in space had lost contact.

In desperation, the senior management had to end the rescue operation in a hurry. Even if it was already in the shelter, no one had hope.

Because through various detectors and the members of the shelter, watching their civilization achievements that had developed for nearly ten thousand 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 shelter thought it was their turn, the attack stopped.

The planet after the attack was devastated, and there were almost no survivors on the entire planet's surface. This was definitely a genocide attack. The entire civilization can be said to have been extinct, because after statistics, the total members of the three refuges were less than 500,000.

Of course, on such a large planet, three great powers, there could not be only three refuges, but when the incident happened suddenly, no one expected that the inexplicable power would attack so quickly. It took less than two days from the start of the attack to the attack.

Secondly, most of the other shelter bases are disrepaired for a long time, and they are almost all simple air raid shelters. Even if they are stronger, they have not escaped attacks.

After the attack ended, less than 200,000 were rescued from outside.

The destruction of civilization was just the beginning, and the survivors discovered that the entire planet suddenly became strangers to them.

Suddenly, like a spring breeze coming, thousands of pear trees blooming. What was destroyed by inexplicable power is not only the traces of civilization, but also the entire ecosystem. However, under the influence of inexplicable power, like a movie fast forward, the entire planet restored its original ecology overnight.

Moreover, no one knew many plants, and then the entire planet suddenly experienced strong geological activities. These geological activities did not last long. After that, the entire planet slowly filled with a strange energy, an energy that had never been seen before.

The refuge is actually called the Doomsday Base. It was built for an extinction event one day, so it resisted geological activities. Moreover, the Doomsday Base also contains the respective civilized achievements of the three countries. Unfortunately, there are too few surviving members and they cannot meet the requirements of civilized rejuvenation at all.

Since then, the number of members of the shelter has not increased significantly.

After careful observation for a long time, the members of the shelter felt that the surface of the earth was no longer dangerous and were preparing to leave the shelter to restore civilization. However, they suddenly discovered that unknown intelligent creatures suddenly appeared on the surface. Now, the members of the shelter no longer mentioned the direction of manifestation and restore civilization.

It’s no wonder that the survivors are timid, because they discovered that these suddenly appearing intelligent creatures can actually master and have these unknown energy! The attack method of these unknown energy is extremely similar to the original attack power!
