In the end of the ice age, I hoarded tens of billions of supplies

After reading the deciphered part of "Xue Zong Notes", Zhang Yi was deeply shocked.

According to Xue Zong's analysis, the time when a large number of warriors, or aliens, appeared among the Three-Eyed Clan coincided exactly with the time of the coming of the end of the world.

Before that, although there were some powerful individuals among them, they were not as terrifying as they are now.

Even the ability of the Holy Spirit Temple to collect [Sacrificial Spirits] was only unlocked after the end of the world.

"The power of collecting souls... Great destruction... And, I saw this name again - Kagago!"

Zhang Yi covered his forehead, feeling his mind was in a mess.

He got too much information in a short period of time, so he couldn't figure out what was going on.

What's more, we must also take into account the limitations of Xue Zong's thinking. These things are just his personal analysis and may not be the historical truth.

Yang Xinxin said to Zhang Yi: "But now, we can basically judge two things based on the known intelligence."

She slowly extended a finger and said seriously: "First, the Holy Spirit Temple of Nash Country and the purple pyramid under the Qinling Mountains are similar energy collection devices. The birth of the Source of God or the Spirit of Sacrifice is their masterpiece."

"But what do they collect?"

Yang Xinxin raised her head, as if she wanted to look at the sky through the thick roof of the villa.

"The Master said that the Holy Spirit Temple had not been activated for thousands of years. Until the end of the world two and a half years ago."

"At that time, the biggest event in the outside world - that is, the surface world where we live - was the advent of the frozen apocalypse. A large number of humans died."

Yang Xinxin looked at Zhang Yi.

"Brother, I have a guess in my mind. Do you want to hear it?"

Zhang Yi rubbed his brows vigorously and said, "Go ahead."

Yang Xinxin said: "Humans have a special energy field. Although we cannot clearly know its source, it does exist."

"The mass extinction brought about by the end of the world caused the death of 95% of the human population on the planet, in addition to the death of a large number of life forms."

"This power is free and exists within the planet."

"And the surviving humans absorbed these powers, resulting in the emergence of large numbers of mutants."

"This is more in line with the promotion method of aliens."

She held out her palm in a grasping gesture.

"By absorbing the power of supernatural beings. It's just like hunting!"

"Then, hunting can obtain their energy. The same goes for the mass deaths caused by nature."

“As for the tribes in the underground world, they knew that such moments would occur in ancient times, so they created devices to collect this special energy field.”

Yang Xinxin’s analysis made a lot of sense. Zhang Yi didn’t say anything, but just nodded silently.

The overall idea was similar to what he thought, but when it came from someone else's mouth, it sounded much more logical and clear.

Zhang Yi touched his chin and said, "I once heard that the creatures on this planet have experienced five mass extinctions. Perhaps those underground tribes are the five generations of [humans] on the planet?"

Zhang Yi finds it difficult to describe them as biological creatures.

After all, it seems that their intelligence is no less than that of modern humans, and they even surpass modern humans in various other aspects.

Yang Xinxin nodded.

“There is indeed such a possibility.”

"To escape the disasters of this world, they abandoned the surface and entered the deeper world."

"If this planet is a house, they gave up the walls and chose to go inside the house. This is because they know that mass extinction will come again eventually."

Zhang Yi lowered his head in thought.

But suddenly, an inexplicable chill enveloped his whole body, causing a layer of white sweat to appear on his back.

"If we analyze it according to this logic, doesn't it mean that... in the endless years of the past, countless intelligent species that ruled the planets have not succeeded in defeating the unknown apocalyptic disaster?"

He looked down at Yang Xinxin: "One day, we will also face such a fate. But..."

He swallowed hard.

"We have clearly survived the extreme cold of the Ice Age and left behind a spark of survival."

Yang Xinxin said calmly: "That means the real crisis is far from coming."

These words touched Zhang Yi's heart.

In fact, he already had the answer in his heart, but he was just not willing to face it.

Even powerful beings like the Gatekeeper of the Underworld, Bai Longzi, and the royal family of Nash had to choose to hide in the underground world.

What kind of terrible and unknown disaster is that?

"If that's the case, we must make plans early! We need to make ourselves stronger. And, learn from them and build a refuge base deep underground!"

This was the first question that Zhang Yi thought of.

"Perhaps Fremons tried to drill through the earth not to find minerals, but to prepare for future disasters."

Yang Xinxin said calmly: "We don't have enough information. We can only guess based on the existing information."

"And building an underground city is not that simple. You have to find an ideal location, ensure there are sufficient underground resources, and have the technical means to at least predict the patterns of earthquakes for hundreds of years to come."

"And to dig a large enough underground city and make it unbreakable. This alone may require all the strength of mankind to be gathered together to achieve it."

Zhang Yi thought of the two underground worlds he had visited.

He had only been to the outer areas of the White Dragon Clan and had never gone deep into them.

But the country of Nash is so huge that it is as large as dozens of human cities.

Even though the current technological level of mankind is already quite high, it is impossible to open it up without a hundred years and the combined strength of all mankind.

The more Zhang Yi thought about it, the more he felt that this matter was difficult to handle.

The most troublesome thing at the moment is that he has no idea what the final destruction that may come will be.

Ice, volcanic eruption, or tsunami.

These natural disasters are not the most terrifying things for him at the moment.

That thing must be much more terrifying than everything else.

After thinking it over, he looked up at the ceiling.

"Xinxin, tell me, is there a possibility for us to migrate to the starry sky?"

He spread his hands. "Look, for example, the moon, or Mars or something like that! Didn't humans already have plans to migrate to outer space?"

After thinking for a while, Yang Xinxin said to Zhang Yi very seriously:

"Before the end of the world, human space technology was a bit difficult to achieve. Because it is not a short trip, but a long-term residence."

"But now... there are some possibilities."

As for that possibility, it is an alien.

Human mutations allow individuals to possess extraordinary wisdom and power, and can turn many impossible things into possibilities.
