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

Now that he had found the clue, Han Chen was no longer anxious.

At this time, being cautious is the most important thing. You can't just 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 frightened.

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

This is a circular square with a diameter of more than 10 kilometers, and there are many branches of roads leading from the square around, 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 complicated, in my previous explorations, I 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, which is 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 even no footprints on the ground when many people pass by, or dust falling 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 it's a big deal to 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 doesn't 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 was observing 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 of 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 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 is like opening a passage to the surface from here. A large number of unknown soldiers from the underground world are attacking the surface world along this staircase-like spiral structure, 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 the result that Han Chen inferred.

After arriving at this conclusion, the first impression immediately formed in Han Chen's mind, as if this was the final result, it 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, after two hours of repeated investigations here, 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.

"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 such a technology is placed in the technologically advanced Star Federation, it would not be surprising to do this kind of thing, but it would seem very strange if it is placed in an eternal dynasty where no technology is developed.

"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 are looking for a avatar with wider and wider roads, 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 complete 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?"
