At the beginning of the era of natural disasters on the ancient earth, due to frequent disasters, sharp population decline, and rising sea levels, the land area was rapidly reduced, and the global food production was seriously insufficient, and famine became the first natural disaster faced by mankind.

Subsequently, the deadly radiation from the ozone hole caused a large number of human beings to die from radiation sickness, acid rain, earthquakes, wildfires, tsunamis, and the inevitable massive impact of meteorites, causing the human race to be wiped out almost overnight.

At a time when mankind had not yet formed a unified government to allocate resources, various countries launched wars in order to grab the last right to exist, small countries were annexed and plundered, and large countries built underground fortresses one after another, transferring all the valuable productive forces underground.

Humanity has lived in an invisible underworld for nearly two hundred years, during which time civilization has declined dramatically, technology has been in the hands of a small group of high-level rulers, and it is a privilege that only at certain times of the year are the "gifted children" who have been selected after going through IQ tests and loyalty tests to enter closed schools, and their learning results will be in the service of these superpowers.

These things are no secret, and they are recorded in the historical documents of the masters of every immigrant spaceship, and are used to warn future generations to cherish their homes and care for the environment.

At the beginning of the era of natural disasters, mankind blamed all disasters on environmental problems, at that time, the immigration spacecraft program and the idea of electronic human consciousness had not yet been produced, and a large number of scientists were committed to restoring the surface ecology and saving the earth's environment.

If the historical record is correct, these radical popular groups demanded that humanity return to its primitive way of life and abandon all the products of modernity, and they did not heed to be dissuaded to leave the underground fortress, believing that if humans returned to nature, the adult animals would be able to solve the deadly natural disasters outside.

Of course, the top of the government is not stupid, in the face of such absurd remarks, they have adopted very tough repressive measures, but in that era of declining education for all, this outrageous theory has instead swept through the underground fortress in a brainwashing way, people put up slogans, hold ***, and even attack those genius children who have been selected to receive education, trying to completely suspend the development of human civilization and truly reduce human beings to primitive people who drink blood and hair.

Even though the government has cracked down on them many times, there are more and more such radical groups in the underground fortresses, their whereabouts are hidden, difficult to detect, and each action has only one purpose, that is, to lead more people to break through the underground fortresses and go to the surface world where they have been absent for a long time.

This kind of behavior is very dangerous in the era of natural disasters, once the underground fortress is opened, the radiation and poisonous gases outside will kill people in minutes, as for how these groups disappeared in the end, there is no record in the historical records, later generations only know that the underground fortress has not been breached, and the unified government has guarded the last habitat of mankind.

Now it seems that these slogans must have been left by the original radicals, and the slogans were covered with newspapers as a cover, which shows that in the underground fortress at that time, the struggle between the different factions of different human ideas was quite fierce.

Shu Yungui retracted his gaze, he didn't remember where he had seen a sentence that said that when disaster strikes, human beings themselves are also a kind of disaster.

When he read this sentence, he was still young and didn't understand the deep meaning, but now it seems that whether it is Ancient Earth, Hope Star Field, or several other planets with human life, the disasters suffered by everyone are actually caused by humans themselves.

Natural disasters are not enough to destroy the human race, because humans have wisdom that other creatures do not have, but it is precisely because of this unique wisdom that human beings are almost on the road to extinction.

Shu Yungui walked up, thinking at the same time, if those radicals really led the people in the underground fortress back to the surface, then the end of the human race would be extinction or all the ancestors, would everyone become primates traveling through the forest?

Faced with this question, he has no answer, and by standing here he has already proved the failure of the radicals, and that the solution of the unified government in the face of natural disasters may not be the optimal solution, but it is very

Effectively, at least humanity survived, and survived peacefully for more than 1,400 years after the era of natural disasters.

The old-fashioned staircase was not long at all, but the underground fortress was obviously deep, and the group had circled the staircase many times, and suddenly, without warning, at an ordinary turn, they saw a man with a skeletal beak standing in the shadow of the corner!

Shu Yungui at the front was shocked, just now everyone was still wondering if Tang Yue was hallucinating, but at this time, hearing the exclamations of the team members behind him, it was certain that this terrible thing was not an illusion, Shu Yungui stepped forward, and a punch hit the opponent's chest, he thought that the other party would resist, but the body fell straight down, smashed on the ground and set off a burst of dust.

"Not a living person?"

Shu Yungui cautiously walked over and kicked the other party's body with the tip of his shoe, and there was a "bang" sound under his feet, which was obviously not a sound that a human body could make.

He glanced down at Lu Ting, Lu Ting understood, and immediately came up to untie the other party's clothes, although the torso was painted with skin color paint, but it was obviously wooden, standing here for more than a thousand years, if it weren't for the perennial closure of the underground and the stable environment, it would have rotted into a pile of wood slag.

"Who put this thing in this scary place?!" Zhu Xinyue said angrily, "Don't be caught by me! Or I'll beat him to death!"

"The person you're going to beat is estimated to have been reincarnated dozens of times." Cheng Sikong walked up from behind her, bent down and picked up the weird bird's beak with one hand, and the connection broke with a "click", revealing the traces of inferior glue on the interface.

"It's the beak of the ancient earth creature crested hornbill, which is glued to the skeleton of a human being, and made into such a strange mask, which should be used by the radicals to perform some kind of ritual to worship nature, and it is just some feudal superstitious activity."

Cheng Sikong picked up the skull again and took a look, sure enough, the brain part was cut off, and the entire skull was formed with a bird's beak to form a mask, the underground fortress was dimly lit because of the lack of energy, no matter who wore this mask, it made people feel panicked, in the era of low national culture, there is nothing easier to demagogue than pretending to be a ghost.

"It is a truth to carry out sacrifices with masks with primitive peoples, there is no special role, it is estimated that there are many similar things in this underground fortress, don't be afraid."

Several little girls in the team who were so frightened that their faces were not very good hid behind Zhu Xinyue, although they came from a highly developed civilized society, and they knew that those ghosts and monsters could not exist, but in this strange and strange environment, where could they restrain the fear in their hearts, and they couldn't help but speed up their pace when they walked past the wooden skeleton.

"Although the matter of the bird's beak skeleton can be explained clearly, it does not explain why Tang Yue saw the sacrificial ceremony."

At the front of the team, Shu Yungui whispered to Cheng Sikong: "None of us have never been to the ancient earth, and Tang Yue has not seen any literature about the ancient earth, even if he is dreaming, it is impossible for him to dream of these things."

Cheng Sikong nodded and said, "I understand, someone deliberately let Tang Yue see this, but now the enemy is in the dark, we are in the light, the best situation is that these are all made by the muse, if the enemy is not only the muse, then we will be in trouble."

"The soldiers will block the water and cover the earth, the other party may want to scare us back, or there is some other purpose, in short, be vigilant, don't fall into the trap of the other party."

The voices of the two of them were extremely low, even in the quiet underground fortress, only each other could be heard, they were not sure how far the muse had developed here, if Tang Yue's thing was done by the muse, then its ability may have exceeded human imagination of artificial intelligence, and it was still unheard of to rewrite the memory of the human brain without the help of any electronic tools.

Of course, no one could be sure that all this was the work of the muse before he found the first generation of muses, Shu Yungui turned his head, separated a whole flight of stairs, and asked Gu Xingtang, "Are all the underground fortresses of the ancient earth connected?"

Gu Xingtang raised his head and looked at it, shook his head and said, "No, due to some geographical reasons, the unified government at that time only established underground fortresses on different provinces of each plate, I was born in the southern province of the Asian plate, and my school was also there

, including the construction of the first generation of the Muse was also there, and later transferred to the African plate, the first generation of the Muse remained in the southern provinces."

"We landed according to the location information you provided, and now that we are in the underground fortress, is this the vicinity where you put the Muse Primordial Aircraft?"

Gu Xingtang hesitated, he looked around, this was obviously a public activity area, and there was still a certain distance from the residential area.

"The underground fortress is built in the form of block modules, the center of each block is the public activity area, and the surrounding area is the residential area, each underground fortress is composed of a different number of block modules, in order to facilitate the construction and installation, all the modules are exactly the same, I am not sure where it has been."

Seeing Cheng Sikong's expression beside Shu Yungui change slightly, Gu Xingtang immediately said: "But I was the muse designed in the government school at that time, the dormitory assigned by the scientific researchers is on the upper floor of the government school, as long as I can find the school, I should be able to find my original dormitory building, as long as the muse is not discovered, it must still be there."

In the period of natural disasters, people do not have their own private assets, all resources are allocated by the unified government, even the housing is allocated, Gu Xingtang, as a senior researcher, has a family, and the allocated house is definitely not small, so that he can hide the muse.

As long as the house is not assigned to others, as Gu Xingtang said, there is a high probability that the first generation of muses will still be in it.

Shu Yun looked up, it was estimated that it would be a long time to get out of the civilian area on foot, and he motioned for everyone to move on, but at this time, Kuang Jiaping stopped again.

As a rare perceptual variant, there are some things that he can be keenly aware of, even if he doesn't deliberately sense them.

He stood at the back of the line with his submachine gun in his hand, and said with a solemn expression, "The door we came in through the vault is gone."
