As the catacomb language class progressed, Fang Ping once again gained some in-depth understanding of the catacombs.

"Based on our many years of exploration and judgment, the cave world can most likely be regarded as a circular plane world."

Although the old experts are language experts, they can study language, which means they have to study everything in the caves in order to deduce the meaning of language based on their situation.

As he spoke, the old expert drew a circle on the blackboard.

Then, on the periphery of the circle, some more shadows were drawn.

"Beyond this circular continent is the sea, an endless sea with no end."

"And the size of this circular continent is immeasurable, because the geographical distribution of the entrance to the cave is not of much reference."

"The circular continent, with a circle around it, is cut into domains!"

The old expert drew a circle again in the middle, and said with a slightly burning look: "These domains are actually the Demon City Caves, Kyoto Caves, and Tiannan Caves that we now divide...

They are connected to each other but not connected, or in other words, there may be a gap between them.

However, in the center of the continent, there is another huge domain, which we assume is the central domain.

The most likely way to connect the major burrows is through the central domain.

In other words, if we want to go from one cave to the next, walking in both directions is not feasible. We can only go deeper, deep into the central area.

At this time, we may be able to open passages to other caves through the central area."

"The strong men in the depths of the caves that we often talk about are most likely strong men from the central region."

Everyone listened carefully. They really didn’t have a clear idea about these things.

Because the cave is too dangerous, non-grandmaster warriors can only wander around the outside. Going deep into the cave means a narrow escape from death. Even if a strong master goes deep into the cave and disappears without a trace, it is not surprising.

In recent years, human beings have not thought about going deep. However, every time they go deep, they will face huge dangers.

Even if a ninth-level expert goes deep into the cave, he will most likely never return.

Fang Ping raised his hand, waited for the old expert to nod, and immediately asked: "Teacher, can I understand that these cave humans we are encountering now are actually a group of poor people on the outermost edge of the cave world?

They attack the Earth and want to open the passage because they cannot enter the Central Domain, but they are not willing to be ruled by the Central Domain, and they hope to open up a new world as a fallback route or a colony?"

The old expert pondered for a moment before saying: "Whether they are poor people cannot be determined, and whether the Central Region is more prosperous and powerful cannot be confirmed yet.

Human footprints are currently unable to penetrate deep into the central area, and there are actually barriers between the periphery and the central area.

It is a huge mountain range that stretches as far as the eye can see. The inner ring I painted may be the real situation of this mountain range, blocking the communication between the inside and outside!

Inside the mountain, there are countless powerful cave monsters.

We judge that there should be a safe passage between the inside and outside, but this safe passage is controlled by the powerful people in the central domain.

There are many ninth-level experts.

As for why the cave humans attacked the earth, we have made several judgments over the years.

First, as you said, they hope to open up a new world, a safe new world. Compared to the catacombs, the earth is actually much safer.

Here, there are no rampant monsters or terrifying Jedi.

Here, you don’t have to worry about being attacked by monsters at any time, and you don’t have to struggle for survival.

However... this point is somewhat different from the fusion theory of the underground cave, because according to predictions, once there are too many passages, the final result may be that they merge with each other.

Once merged, the safety theory becomes untenable.

The second is pure aggression. After discovering the new world and discovering that the humans in the new world are not strong, it is a normal idea to invade the earth.

After all, many years ago, human beings were indeed not strong and had only a few masters.

At that time, if they could open the channel, the earth would be almost within their grasp.

Third, there might be something on Earth that would be of great benefit to them."

The old expert hesitated slightly and said: "I can't judge whether it is true or not, but in my opinion, the third point is actually more likely.

Because if it is for invasion or expansion, there is no need to kill everyone on sight.

The cave warriors, on the other hand, would hardly hesitate when they broke into the human world and would kill anyone they saw. They didn't even think of taking prisoners.

Several old friends and I made an unconvincing judgment.

That is, there are things on earth that they are determined to obtain.

Killing, perhaps for sacrifice.

It may be necessary to massacre local residents in large numbers.

Of course, at the beginning, they may have considered the weakness of human beings, so they did not consider negotiating with us, and the purpose was to exterminate human beings.

However, they underestimated the strength and potential of human beings, and with the development of modern weapons, when some cave warriors rushed out of the passage, they were not killed by warriors, but died at the hands of technology.

After this..."

The old expert hesitated again and thought for a moment before saying: "After that, the humans in the cave may have had the idea of ​​breaking through the human defense line from the inside. I have always guessed that the founder of today's cult may have entered the cave back then.

Some strong men.

These people may have had contact with, or even had negotiations with, the higher-ups of the cave in the cave.

Perhaps, they truly know the purpose of the crypt.

But the founders of these cults are very hidden."

The old expert looked slightly ugly and said: "Cult warriors and human warriors are actually the same and cannot be distinguished unless their purpose is revealed.

These people may be hiding among us, or even occupy high positions.

But because of his weak strength, he didn't dare to show his face, or he was planning something.

Now, some of the cult warriors we have killed, including the cult's top brass, are actually chess pieces that were brainwashed and cultivated by the cult itself before they entered the caves and later joined the cult.

We have never been able to find the real core."

Seeing that these words made everyone change their minds, the old expert smiled and said: "Of course, there is no need to worry too much. Even if it is as I guessed, these people are only a minority, and they will not be the real top leaders of mankind.

Because the real top leaders of mankind have gone through thousands of procedures for review.

Moreover, the cult has been around for many years, and the founders back then are all older, so the leaders of mankind are all middle-aged and middle-aged people."

Seeing this, the old expert smiled again and changed the subject: "In addition to the above three points, there is actually another point of judgment.

That’s for the sake of the planet itself!”

"The Earth itself?"

"Yes, there are countless planets, satellites, planets, and stars in the vast universe.

However, over the years, among the planets that have been discovered, only the earth has life forms, which is actually enough to illustrate the special nature of the earth.

As for the cave world, you have discovered that they do not have the concepts of planets and stars.

There is a high probability that the cave world is not a planet because the cave is too big. If it were a planet, humans might not be able to survive if they entered it due to the difference in environmental gravity.

The earth may be a unique product for the cave world.

There was a fusion theory before, but I think it is better to change it to a sacrifice theory, or a swallowing theory. The cave world may want to swallow the earth.

Once the swallowing is successful, the energy concentration of the cave world may increase greatly, or it may transform from an inanimate body into a living body.

The earth is actually alive.

It has a depletion period, which means it has life and a lifespan, which may not be the case in the cave world!"

The rise of what the old expert said, regardless of what everyone thought, added: "Human beings, including the cave humans, are actually pursuing evolution, the evolution of life.

And what if the cave world and the world itself are also pursuing evolution?

Maybe the cave world is dry and lifeless, but since there are living creatures such as cave humans and monster beasts in the cave world, it also means that it has certain special characteristics.

Or, it could simply be that in the cave world, a group of strong men who have reached the end of the evolutionary road, facing the situation of no way forward, suddenly thought that by swallowing the earth and giving life to the cave world, they can go further...

All this may not be impossible.

Because in our opinion, the emergence of underground cave passages cannot be accomplished by these underground cave warriors we have encountered so far.

Individual channels can be regarded as coincidences.

But when these passages appear in an orderly manner, it may not be a coincidence.

As for why those strong men have not appeared so far, maybe they are waiting for an opportunity, maybe there are some restrictions, or maybe the strong men in the cave are restraining each other and are not of the same mind.

The cave world actually has a somewhat subtle attitude towards the human world.

Some cave cities will take the initiative to attack the earth, while most cities will just sit back and watch.

We can also understand that these cities do not actually belong to the same force. The cities that are watching from the sidelines may belong to those strong people with different opinions.

In recent years, there has been cooperation within the catacombs. It can also be judged that some powerful people who were previously unclear about their attitudes are now gradually reaching an agreement, and thus there is a trend of joint attacks.

If these judgments are correct, then more powerful people may reach an agreement next.

Once this happens, the situation in the cave will become even more dangerous.

Those cities that had been on the sidelines before may gradually join the war..."
