Han Chen was talking to himself as he headed underground.
However, he suddenly realized that he seemed to have said something right.
¡°Ecological structure, yes, ecosystem!¡±
Han Chen suddenly woke up.
Whether it is the Earth or the Zulong Planet, there is a complete ecological circle. Under the large ecological circle, there are also some small ecological circles, large and small.
It¡¯s just that if those small ecological circles want to maintain their own vitality, they must regularly exchange materials with the large ecological circle, so that they can achieve the effect of running water without decay.
And those defense facilities were successfully built in the old era before the advent of the divine realm. In other words, the enemies defended by those defense facilities should also belong to a civilization.
So, if there are really enemies in the underground world, then there should be a complete ecosystem in the underground world.
If you do not meet this condition, you will not be able to survive in the old era.
Of course, this ecosystem does not necessarily have to be in accordance with human standards, but no matter what, such an ecosystem should exist.
¡°Perhaps this is originally an ecosystem, but it¡¯s just a little different from the earth¡¯s ecosystem. It¡¯s not even an ecosystem that chooses meat life at all.¡±
"You can't think according to the usual thinking of human beings. You must escape from this idea. There are many races in the God's Domain such as the Balrog Clan, the Rock Clan, the Elf Clan, etc. The ecosystem is also full of strange things, even flesh and blood life and plant life. What it occupies is just a place among living things."
"So, we cannot judge based on common sense."
"Of course there is a bigger question, and that is why the surface world, even at the expense of some 'sentinels', still conceals news about the underground world."
"The emperor of the Eternal Divine Dynasty has absolute authority. The common people do not dare to resist the nobles, and the nobles also do not dare to resist the royal family. Even if such news is accidentally spread, what kind of impact will it have on them? It should be That¡¯s not the case!¡±
"For them, civilians only need to accept orders and obey rule. Can they still resist?"
¡°I always feel like I¡¯ve overlooked something.¡±
"what is it?"
With such doubts, Han Chen continued to go deep underground.
"Five meters, six meters, 7 meters 2, 9 meters"
The deeper you go, the wider the passage becomes.
When the width of the passage reached 12 meters, Han Chen slowed down.
After a period of rest, Han Chen sent out his avatar this time to continue marching toward the underground, just like he used his avatar to test it just now.
If the upper passage is used to transport troops, then the place where the bottom passage leads is most likely the core of this special ecological circle.
The Eternal God Dynasty has abandoned those abandoned military facilities. In all likelihood, there should be no threat from the enemies representing the underground world, but this is not absolute.
Han Chen will not place his hopes on the information of the Eternal Divine Dynasty.
Even if they think so, it doesn't mean their information is correct.
With this idea in mind, Han Chen finally came to a "city".
This is a huge square with a diameter of more than a hundred miles. It seems to be the same as the square above where troops are gathering to prepare to attack the surface world. However, the biggest difference from the square above is not its area, but the various kinds of things that exist in this square. All kinds of strange facilities.
The height of the square is also more than 30 miles high. Hundreds of huge pillars are supported here. There are also some "stairs" on the pillars themselves. People who want to go from top to bottom can go to the square.
There are no houses or common urban buildings here on earth, but some buildings that Han Chen can't describe directly.
These buildings have all kinds of strange shapes. If it weren¡¯t for the fact that the styles of many buildings are completely repeated, Han Chen would have thought they were formed naturally!
These strange buildings, if you only look at them from the surface, they should have no function.
From a human perspective, it seems that these things have been abandoned.
"No, it cannot be limited by human perspectives and thinking patterns. Things in the underground world are not necessarily human beings. No, they are not even human beings at all."
"So, they probably don't need houses or walls, and if they don'tIf you develop your own civilization and it is just a model of social creatures, you don't even need clothes and weapons. "
"The repetition rate of these buildings is very high, indicating that they should be artificially constructed."
"So, for them, the most important purpose of these facilities should be to solve the food problem. After all, no matter what life is, it cannot be separated from the absorption of energy. These facilities should be some kind of means to solve the food problem, and it does not rule out that Other uses.¡±
"There are no traces of life activities here. Have the traces here been deliberately erased? However, even if the traces are deliberately eliminated, the traces themselves should leave traces, right?"
"If the traces of those details have been completely eliminated, why leave such a passage and such a 'city'?"
"Have I made the mistake of thinking about the problem from a human perspective again?"
"No, there are only so many human perspectives. Even if you look at it from the perspective of a legendary existence, it is nothing more than that. Why should you consider things that are impossible to do?"
It's like trying to remove fingerprints from a crime scene. If you rinse it with water, it will leave water stains on the scene. If you wear gloves in the first place, it will also be obvious that a person wearing gloves committed the crime. .
Wearing the glove itself is a clue.
So even if the traces are eliminated, and the method of eliminating traces is perfect, it will only make it impossible to find clues about the person who found the plan.
¡°However, it is almost impossible to completely eliminate the evidence of guilt.
But the traces on the scene were so perfect that even the smallest details did not exist. This degree of perfection was simply terrifying.
After all, there should be some leftovers left in the creation of these things.
However, under such perfect elimination of traces, traces of passages and cities are left behind. This process of perfect elimination of traces has left an indelible stain.
Even if the environment here is directly destroyed, it is better than preserving the site!
"There must be some possibility that I haven't thought of."
While Han Chen was searching and recording all traces here, he was thinking hard to find a possibility for various phenomena.
"Could it be that this is what this place was originally like?" (Remember the website address: www.hlnovel.com
