Aware that he has become more and more close to the end, Han Chen in the heart of the alert increased a few points.

After another two hours of marching, Han Chen's demon body stopped.

Instead, it's his split body that accelerates forward exploration.

If there is danger ahead, the disappearance of the separation can give the noumenon enough reaction time. If there is no danger ahead, and the noumenon needs to go there in person, it will not waste much time.

Now that he has found the clue, Han Chen is no longer in a hurry.

At this time, prudence is the most important thing. We should not miss such a good opportunity because we are greedy and rash.

Even if the wise man of the month agreed to let him continue to send avatars, it was inevitable that he would be alarmed.

Two hours later, one of his characters came to a "open space".

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

"It is found that the branches of the square go up. Considering that the eternal God on the ground has defensive measures against the underground, it is not surprising that there are some places to gather forces and attack the ground."

"Although the roads here are complicated, in my previous exploration, I have also found some rules, that is, all continents are built around some" pillars ", which should be the basis for supporting the underground world from collapsing."

"Otherwise, if we dig out a lot of open space rashly, 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, just like dividing traffic lanes into several directions."

"But at present, there is still a doubt, that is, why there is no trace left on these roads? Not even the footprints that many people tread on the ground when they pass, or the dust from their bodies? "

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

"After all, they didn't wear a watch to enter the divine realm. The things that represent the underground may be human beings, but they should not be human beings in nine out of ten cases."

"Since it's not human, it can't be seen from the perspective of human beings."

"But I think it's like there's some key clue back just now."

After thinking for a while, but without any discovery, Han Chen decided to go to see the "square" in person.

Han Chen still has enough confidence in his IQ, but his IQ is not reflected in the strategy, but in the responsiveness.

Therefore, for a time did not expect, Han Chen will not be too rigid.

Anyway, he has collected the information here. It's a big deal to find someone to analyze it after he goes back.

During the rest just now, Han Chen has analyzed the general structure of the underground world, so it doesn't take two hours to go to the square.

Knowing the general structure, he took a short cut to the square in 15 minutes.

When he came to the square, he opened the eyes of the night devil.

From the perspective of the night devil's eye, he observes everything around him.

"It is clear that there are such detailed road planning here, and the traces of human development can be analyzed, but there is no trace of chopping and chiseling, as if all of these were made by nature."

"If we say that this is the marvelous work of nature, it would be too intimate for human beings."

"The rocks here seem to be layered."

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

In his view, the rocks in the ceiling direction seem to have some special features. Under this depth, most of the rocks are sedimentary laminated rocks and magmatic rocks cooled by magma. However, in his perspective, he sees some dry soil or aeolian rocks on the surface.

Such a discovery and Han Chen's previous conjecture confirm each other, and soon came to a conclusion.

"If these things really come from the earth's surface, it's like opening a passageway to the surface from here. A large number of unknown soldiers from the underground world attack the surface world along this ladder like spiral structure, but they are finally found, so this passage is buried again."

According to the clues obtained before, as well as the present findings, this is the result of Han Chen's inference.

When he got this conclusion, he immediately formed the first impression in Han Chen's mind, as if this was the final result, which was also an unquestionable truth.

After all, now that all the clues have been connected, only the final confirmation is needed.

"It seems that there is nothing wrong with it."

Because this seems to be a very important reason, Han Chen here after two hours of repeated investigation, and even turned into a shadow, flying up for a period of time.After repeated investigation and confirmation, Han Chen has roughly confirmed such a conclusion.

Although there are some doubts in my heart, they are all unimportant details. Now the most important thing for him is to make the final confirmation.

"There are still some doubts, that is, why the earth's surface can be buried for more than 3000 kilometers. Even if such a technology is put on the earth, it can't be ignored. After all, it's on the spiral staircase and can't be directly instilled."

"If such a technology is put in a technologically advanced Xingyao Federation, it is not surprising to achieve this kind of thing, but it is very strange to put it in an eternal God without developing any technology."

"But that's not the point. There are some differences between the development routes of the two civilizations. Even if they do something that can't be done on earth, it's not surprising."

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

"The road leading to the square is getting narrower and more complicated, but the overall direction is upward. My two sentences are looking for a branch of the road that is wider and wider. The overall direction is downward, that is to say, the more down the place, the wider the space."

"Well, the underground world should have a perfect ecological structure. Forces are generated from a certain place, and then they are transported through such channels to attack the surface. If people in the surface world find enemies from the underground world, they will directly block the passage and directly use 3000 kilometers of thick earth as shields. Such defense facilities are better than any other defense facilities Facilities should be effective. "

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