After searching for a long time, Wu Ye'er, who had no experience, reluctantly found a stone cave under the leadership of Xue Buyan, and increased the speed of excavation to the limit, coupled with the joint efforts of the two people, only after nearly three hours of excavation, a road to the stone cave was made. It took another ordinary effort for Wu Ye'er and the others to find out where this cave seemed to lead.

Looking at this dark cavern, which seemed to be beckoning to people, it seemed to contain all the filth and unbearable, and waited for people to enter. Looking at this terrifying cave like a black hole again, Wu Ye'er was even more scared in her heart, saying that it was false not to be afraid, who knows what is down there, what is dangerous? Or the living dead are possible. Anyway, the unknown is definitely something to be scared of.

Xue Buran also took a deep breath.

It's too deep, and she can't see it when she probes down with her divine sense. Wu Ye'er didn't know how terrible this place was, but she still had divine sense, and she could avoid the fearless thoughts of the ignorant, and she felt this frightening sense of fear most intuitively.

Deep, too deep, too deep.

This place was like the end of the world compared to the cliffs or pits, and if someone told Xue Buran that she could jump from here to the other side of the world, she thought, she would believe it, because it was too deep. It's like a place that existed in ancient times, and now it is called for, and now it is quietly waiting for them.

Looking at this dark cave like eternal night, Wu Ye'er still took Xue Buzhi's hand and walked forward together.

It doesn't seem so scary, it's a huge space. The illusion on the outside seems to be just to scare away the faint-hearted so that they will retreat, and the courage in their hearts keeps them from giving up this opportunity. Otherwise, if you only look forward and backward outside, you will miss this place in this life.

There are some huge buildings, as high as if they are about to touch the spire of a huge space, and they are taller than the highest peaks, or rather like mountain peaks, standing there, glowing with purple and red light.

Every building is like a strange shape, there are all shapes, flat, wide, long, tall, short, but one thing in common is that they are all very big, big and scary. Any one is as big as a city, so big, but compared with the city, something of this structure must be indestructible, and if it collides with the city, the city is afraid that it will be shattered into slag.

In Wu Ye'er's knowledge reserve and cognition and insight, it seems that he has never seen this kind of building, there are no heard, no legends, and there are no ancient books that record this kind of thing. Looking at these huge buildings quietly, there is no sense of familiarity at all, as if it is out of place in this world.

At the beginning, I heard Senior Brother Wufeng say that in this world, outside this sky, there are even higher creatures, and they can rely on advanced technology to go anywhere and soar in the universe and the galaxy. In order to fly, humans cannot evolve wings, and can only rely on intelligence to obtain things that allow me to fly to the sky. Wu Ye'er didn't know how long she stayed after listening to Senior Brother Wufeng's words. She just felt that the world had become, so many bizarre things, a lot of conventional truths had been broken, and it had become messy. But Senior Brother Wufeng also said that there are some things that cannot be explained by science, and that may be theology, this world exists in God, and God is the beginning of all things in the universe.

During that time, she listened to Brother Wufeng's lectures and listened to many lectures, although Brother Wufeng's theories were not completely absorbed, but although she didn't remember everything, she still had some understanding of concepts and concepts. Even if you can't say it, you can still think of it.

The strange buildings here do have round, like a plate, with a metallic sheen on the outside, and no windows or superfluous ornaments. It's huge. Senior Brother Wufeng also said that in his world, he didn't know much about this thing, but only half-understood, so he couldn't rely too much on Senior Brother Wufeng's knowledge to look at the things in front of him. But it's estimated that it's still eight or nine ten, so huge, and metallic, and not rotten, and there is a strange light. Compared to what Senior Brother Wufeng described, it was much, much bigger.

Just looking at this thing, I feel uncomfortable, I have seen the highest mountain at the beginning, it stands to reason that this thing is about the same height as that, but the majesty or something is not a level at all. This thing is just one, the weakest, the smallest one, and the worst oppressive one, which also gives Wu Ye'er a feeling of "this thing can destroy the world, and this is not an illusion" You know, although this thing is very big, it is still far inferior to the world, but it can give that feeling. No matter how big a world is, a person may not be able to complete it in his entire life, and even if it is the activities of tens of billions of human beings, it is impossible to fill the world. But this thing can, it can destroy the world, which means that it can wipe out humanity at will.

Xue Buyan's heart was also shocked, and she probably had a bold guess about the reason that led to the extinction of the immortals. This kind of thing, something that can destroy the world, how can it be a joke to compete with immortals? If it is like what Wu Ye'er said just now, if the alien civilization invades this world, the immortals will definitely stop it, and they will definitely not move the battlefield to mortals, they should seal the two worlds and do a good job of protecting mortals. But...... That war was too cruel, too terrifying, not even an immortal could destroy the world. And their opponents can, opponents with advanced technology, the immortals can only face it bravely, and do not retreat for the sake of the future of the human race.

Maybe in the end, the immortals sealed the aliens here, but there were only the immortals who survived and were in danger, and in the end, the treatment was not timely, or it was too late to be treated, so they died helplessly. Ended the immortal civilization.

Stroking one strange building after another, Xue Buyan was still looking for it, the guess in her heart, the thoughts that suddenly arose to her now, kept walking, kept early, and finally even Wu Ye'er was shocked by her behavior, and spontaneously found it for her.

"Didn't you? Corpses or remnants, nothing? Not only the corpses of immortals, but also the corpses of foreign races, where and where are they. Still alive? Or are they all dead? ”

"How can it be so clean, it can't be so clean, there must be no trace. Impossible, if ...... Is there one party who hasn't died yet? Should it be killed, or should it be saved? The beast that has lost its checks and balances is the most terrifying. ”

Constantly refuting his remarks, constantly talking, and constantly searching, Xue Buyan and Wu Ye'er didn't know how many things, but they still didn't find anything, except for a few strange buildings that had been over there all the time and could be easily seen. I've been looking for it for so long, and there are still no bodies or residues or anything. As Xue Buye said, it's too clean, and it's too weird to be clean.

That's right! Senior Brother Wufeng said that these things can be opened. Wrong...... What can be opened is a flying machine made by a low-level civilization, and this is probably like what the senior brother said, sucking people in, or "teleporting in", in a mysterious and mysterious way.

Although she has thought about everything clearly, it is useless, it is not enough to think things clearly, she has to find the key things, even if not for the sake of the snow, but also for her own curiosity. But after looking for so long, there is still no breakthrough progress, and Wu Ye'er will inevitably feel a little sad at this time. But if you are not sad, you can only work harder to find it.

After searching for a long time, Wu Ye'er also found some other patterns. These strange-shaped buildings, although completely different, all have a connection in place, such as they can be put together, or they can be divided into five types if they are classified.

"That's right! That's right! That's how it should be! ”

"The place where these things are placed is exactly the direction of the gossip, Ye'er, you stand in front of that circular building, listen to my command......"

An inspiration moved, Xue Buyan connected everything, and the next moment she walked to a position, looking at the light that suddenly flashed nearby, her confidence increased a little more, and began to direct Wu Ye'er to go to other places, while she went to another place, and as they went, the ground also lit up a lot of light, black and white, the two of them were like, one white, one black, evolving the changes of the gossip, gradually evolving to the poles, and finally became a Tai Chi pattern.

And this lesson, like the sound of glass breaking, was very crisp, and in the following time, the spatial cracks were exposed, eating most of the buildings. The look on Wu Ye'er's face became crazy and shocked, and she kept looking at the buildings that were gradually being smeared, and kept muttering: "That's it, that's it." As an immortal, they had long expected that we would come here, and they deliberately arranged their backhand, waiting for future generations to come and clean up the remnants. Xue Buyan's words, Wu Ye'er listened to them, and probably had an understanding of the matter, it should be the original war, some aliens were sealed in these buildings, but the immortals did not have the strength to completely wipe them out, so they could only arrange a formation, waiting for the people who came in the future to destroy them. But is that really the end there? Seeing that the goal of the snow was not stained, Wu Ye'er also let go of her mind with all her might, and the butterflies of thought were still flying in the sky. At this time, there was before, and in the future, there was a line that connected all of them, and her mind exploded in full force.
