Realizing that he is getting closer and closer to the end, Han Chen's vigilance has increased a bit.

After traveling for another two hours, Han Chen's Night Demon body stopped.

Instead, his clone accelerated his exploration.

If there is a danger in front, the disappearance of the clone can give the body enough time to react. If there is no danger in front and the body needs to go there, it will not waste much time.

Now that the clue has been found, Han Chen is no longer anxious.

At this time, being cautious is the most important thing. You should not miss such a good opportunity just because you are greedy.

Even if Yue Sage agrees to let him continue to send an avatar, it will inevitably be shocked.

After another two hours, one of his clones came to an "open space".

This is a circular square with a diameter of more than 10 kilometers, and there are many branches of roads leading to it from the surroundings of the square, and of course some branches come from the ground of the square.

"The branch of the square is found to go up. Considering that the eternal gods on the ground have defensive measures against the underground, it is not surprising that there are places where there are gathering forces to attack the ground."

"Although the roads here are intricate and complicated, in my previous explorations, I have also found some rules. That is, all continents are built around some'pillars'. These pillars should be the foundation that supports this underground world from collapsing ."

"Otherwise, if you rush to dig out a lot of open space, even if the gravity of the underground world is smaller than that on the ground, the possibility of collapse will be much greater."

"So these intricate roads, in fact, are basically the same road, divided into several directions just like dividing traffic lanes."

"But at present, there is still a doubt, that is why there are no traces left on these roads? There are not even the footprints that many people step on the ground when they pass, or the dust that falls from their bodies. What?"

"Is it because of the special underground environment? Or those things from the underground world have their own special characteristics?"

"After all, you didn't wear the God's Domain watch to enter the God's Domain. The things that represent the underground may be humanoid creatures, but in all likelihood they are not humans.

"Since it is not a human being, it cannot be seen from a human perspective."

"However, I think it seems that some key clue has just come back."

After thinking for a while, but not finding anything, Han Chen decided to go and see the "square" in person.

A wise man must have lost his mind. Han Chen still has enough confidence in his IQ, but his IQ is not reflected in strategizing, but in response.

Therefore, unexpectedly, Han Chen would not be too rigid.

Anyway, he has collected the information here, so he can find someone to analyze it together after returning home.

During the rest just now, Han Chen has already analyzed the general structure of the underground world, so now when he heads to the square, he does not need two hours.

Knowing the general structure, he took a shortcut to the square in only 15 minutes.

After arriving in the square, he opened the eyes of the night demon.

Under the eyes of the Night Demon, he observed everything around him.

"There is obviously such a detailed road plan here, and it can analyze the traces of man-made development, but it does not leave any traces of knives and axes, as if all this is natural."

"If this is the supernatural work of nature, it would be too intimate for humans."

"The rocks here seem to have layers."

Han Chen raised his head and looked in the direction of the ceiling.

In his field of vision, the rocks in the direction of the ceiling seem to have some special features. Below this depth, most of the rocks are deposited layered rocks and magmatic rocks formed by cooling of magma. But in his perspective, he What I saw was some dry mud or wind-cracked rocks on the ground.

This discovery and Han Chen's previous speculation confirmed each other, and a conclusion was quickly reached.

"If these things really come from the surface, it seems that a passage to the surface has been opened from here. A large number of unknown soldiers from the underground world are attacking the surface world along the spiral structure of this ladder, but in the end It was discovered, so this passage was buried again."

Based on the clues obtained before and the findings now, this is what Han Chen inferred.

After arriving at this conclusion, the first impression that immediately formed in Han Chen's mind, as if this was the final result, was also an unquestionable truth.

After all, all the clues are now connected, only the final confirmation is needed.

"It seems, there is nothing wrong."

Because this matter seems to be an important reason, Han Chen has been here after two hours of repeated investigations, and even turned into a shadow and flew upwards for a while.

After repeated investigations and confirmations, Han Chen has roughly confirmed this conclusion.

Although there are still some doubts in his mind, they are all unimportant details. The most important thing for him now is to make the final confirmation.

"Now there are still some doubts, that is, why the surface world can be buried down more than 3,000 kilometers. Such a technology cannot be ignored even if it is placed on the earth. After all, this is on a spiral staircase. It cannot be instilled directly."

"If this kind of technology is placed in the technologically advanced Star Federation, it is not surprising to do this kind of thing, but it is very strange if it is placed in an eternal dynasty that does not develop any technology."

"But this is not the point. There are some differences in the development routes of the two civilizations. Even if they do something that cannot be done on earth, it is not surprising."

"The most important thing now is to confirm what the enemy of the underground world is."

"The road to the square is getting narrower and more complicated, but the whole is upwards. My two sentences look for the avatar with the wider and wider road, and the overall direction is downwards, that is, the more Where it is down, the space should be wider."

"Then the underground world should have a perfect ecological structure. Forces are generated from a certain place, and then they are sent through such a channel to attack the surface. If people in the surface world find an enemy from the underground world, they will directly The passage is blocked, and the 3,000-kilometer thick ground is directly used as a shield. Such defense facilities are more effective than any defense facilities.

"Wait, what did I just say? Ecological structure?"
