Gears of different sizes were turning in front of several people, and dozens of stone slabs were hanging from the iron cables, which should be the stone walls that blocked them, and they were now presented in front of their eyes.

The sound of the gears running is not small, and it feels deafening to hear it after passing through the wall, but on the other side of the wall there is no sound to be heard, which is obviously specially designed.

These mechanisms were made up of only gears and iron cables, and then some iron plates, but even so, the three of them still couldn't see through these mechanisms, and they didn't know what their role was.

But Jiang Xueyan inexplicably felt that this place was very familiar, and she always felt that she had been here, but that was impossible, she felt that the familiarity might be because of the underground ruins of the old city, and thinking of this place suddenly had a flash of inspiration.

This is not the underground ruins of the old city, it is the underground passage of the old city auction house, that is, the place that is blocked by the wall before entering the ancient ruins, but there are more of these mechanisms!

This may explain why there is no way to move the underground ruins of the old city, and there is no way to illuminate the entire ruins with the sunlight of a hole as here, because the mechanism has been demolished.

However, it is still a bit hasty to draw conclusions like this, not necessarily that it was demolished, or that it did not exist from the beginning, because the ruins of the old city may have been imitated.

And it was intended to be fixed in that position, without the threat of alien beasts and without defense, so that everything could be explained, except for the frescoes.

If you think about it this way, maybe this ruin was not built by the Nightmare Clan at all, the Nightmare Clan just kept it for themselves, and the one in the old city was built by them.

Jiang Xueyan is also a talented woman of the royal family, and this reaction speed is still there, assuming that this site itself has existed for a long time, and the Nightmare clan accidentally discovered it and took it for themselves.

Later, those stone statues were built here, and then another one was reproduced on the Xuling Continent, and a mural prophecy was left, which makes sense, but it lacks a very important answer.

That is, who built this site, and it is definitely not simple to be able to design such a complex mechanism, but Jiang Xueyan can only think of so much, and she doesn't know more about it.

Zhao Xue and Han Hao haven't woken up from the shock yet, everything here is beyond their cognition, and the two of them who haven't been to the underground ruins of the old city won't feel familiar, so they won't think too much.

At this moment, Zhao Xue's ears suddenly remembered Guo Chen's voice, forcibly woke her up, and said, "Where are you now, come out of the wall immediately, and we will look for you later." ”

Zhao Xue didn't reply, but just told Guo Chen's words to the other two, of course the two of them would not resist Guo Chen's instructions, and once again cast the Heavenly Demon Shadow, passing through the wall and returning to the labyrinth.

Qinglong and Baihu regained their sense of the location of several people, and reported it to Guo Chen, who rushed to the location of Zhao Xue and the others under their instructions, Guo Chen now wanted to know what was behind it.

No matter what is behind it, it must have something to do with this site, and if it has something to do with this site, it may have something to do with the crystal, and now what Guo Chen wants to know most is how the crystal appeared.

With the instructions of Qinglong and Baihu, Guo Chen, Shen Xuan and Ling Yunhao quickly joined Zhao Xue, Jiang Xueyan, and Han Hao.

Since you are lost, you can stay where you are, at least you can ensure that you don't get lost, if it weren't for the green dragon and the white tiger, it would be too difficult for them to converge again.

But this time they had an unexpected gain, so Guo Chen didn't scold too much, just said a few words of meaning, and after finishing speaking, he couldn't wait to rush over the wall.

The other five people also followed, and the reaction of the previous three was very similar, but this time the three people had all been to the underground ruins of the old city, so they all had similar thoughts as Jiang Xueyan.

After being stunned for a long time, Guo Chen, who frowned, spoke: "What the hell is going on, it's not the Nightmare Clan, who else can build such a complex mechanism, it's impossible!"

There are three people who can understand Guo Chen's words, but two people can't, Zhao Xue and Han Hao, the two who have not entered the underground ruins of the old city, they can't understand what Guo Chen is saying at all.

Now they still think that this is built by the Nightmare Clan, and they naturally can't understand Guo Chen's words, but they didn't ask, anyway, the puzzle was already written on their faces.

Ling Yunhao just wanted to speak, but Shen Xuan covered his mouth, raised his chin slightly, and motioned for Ling Yunhao to look at Guo Chen, not only Ling Yunhao, but everyone else also looked at Guo Chen according to what Shen Xuan pointed to.

Then they saw that Guo Chen had already begun to observe the structure of these organs, which was indeed a matter that should not be disturbed, so it was natural for Shen Xuan to stop Ling Yunhao.

The others waited for Guo Chen silently, waiting for him to see through the structure of the mechanism, and then telling them, and then knowing the structure of the mechanism and staying away, they took advantage of the situation to solve the mystery of the crystal.

But they waited for half an hour, and they didn't see any reaction from Guo Chen, so they kept observing the structure of the mechanism, and at the same time muttering something in their mouths, as if they were trying to find a way to understand the structure of the mechanism.

Now half an hour has passed, and there are very few mechanisms that Guo Chen hasn't seen through for so long, this structure is already here, it should be very simple to see through!

Shen Xuan definitely couldn't stay any longer, just now he found out that Jiang Ling didn't follow, and now he was wondering if he had found something and wanted to go back and see, so he did it.

didn't tell anyone, and rushed out directly, Guo Chen didn't react, and he didn't know if he didn't notice it at all, or he didn't care at all, anyway, Shen Xuan left.

The others just glanced at the wall where he went out and continued to wait here, Zhao Xue and Jiang Xueyan didn't know what he was doing at all, although Ling Yunhao knew, but this time he didn't dare to leave.

Jiang Xueyan and they didn't keep up last time, this time they can't let the situation of last time happen again, even if Guo Chen is here, Ling Yunhao doesn't dare to be separated from the others easily.

This time is a great luck in misfortune, he can find here, but this kind of thing happens once is already very lucky, Ling Yunhao doesn't think it can happen a second time, so he chooses not to follow.

After Shen Xuan left, he went straight to the altar, he had already written down the route when he was looking for Jiang Xueyan and the others, and now it was very simple to go back, and he quickly rushed to the exit of the maze.

Then he saw Gangneung looking up at the altar, standing motionless in place, so he looked up, and then he found what Gangneung had found before, two different glimmers.

Now it may not be appropriate to say this, after absorbing the power of the sun for a period of time, although the black light is still a faint light, the white light has become obvious, and the black light reflected is very inconspicuous.

Jiang Ling noticed his arrival, glanced back at him, and said, "There is good news and bad news, which one do you want to hear first?"

"Whatever. ”

Shen Xuancai didn't play this with Jiang Ling, one sent him away casually, anyway, both news have to be heard, it doesn't matter which one you listen to first, it won't affect the result anyway.

"The good news is that I've pretty much mastered how crystals appear, and the bad news is that if I continue to let crystals spawn, the beasts will inevitably come back, and there is no room for recovery. ”

After thinking about it for a while, Gangneung now has a complete understanding of how the crystal appeared, just as they guessed, it requires two powers, yin and yang, but not necessarily yin and yang.

It just needs yin and yang, this altar has a way to purify spiritual power, yang comes from the sun's light, yin comes from alien beasts, and when enough yang power is absorbed, the crystal has actually been generated.

The one that Han Hao got before actually had no yin power at all, just pure yang power, and later absorbed the spiritual power in the alien beast and Han Hao's body, and purified it to become the power of yin.

What the alien beast really wanted should be the kind of crystal that Shen Xuan had smashed the spirit beast's body before and exploded, which had absorbed enough power of yin and yang, which could explain why they didn't just snatch it.

But if that's the case, it's going to be an endless loop, and the hole won't be blocked by the trap until the crystal appears, and it will continue to absorb the power of the sun until the crystal appears.

And the hole is blocked by the mechanism, which proves that the alien beast is coming, and the alien beast must be heading for the crystal, even if the mechanism is closed, it can't prevent the alien beast from sensing the crystal to seize it.

After the beast is gone, the mechanism will be turned on again, and even if they can solve a crystal, there will only be more and more crystals that keep appearing, and they will definitely not be able to dispose of them all.

In other words, they need to keep an eye on whether the crystal appears now, and if the crystal appears, they must bring it into the volume realm as soon as possible, once it is a step too late, the beasts will regather here.

After listening to Jiang Ling's explanation of the crystal generation method to him, Shen Xuan did not hesitate to turn around and rush into the maze again, Jiang Ling didn't stay by himself this time, and followed in, it seems that they should have discovered something.

The two of them moved forward at full speed, and soon returned to the dead end, Jiang Ling was stunned for a moment, Shen Xuan had already turned on the Heavenly Demon Shadow and rushed over directly, and Jiang Ling, who reacted quickly, also hurriedly rushed in.

Like the others who saw the structure of these organs for the first time, Jiang Ling was also shocked, and at the same time, he also knew why Shen Xuan rushed back in a hurry, there should be a way to control the organs.

As long as they see through the structure of these organs and find a way to control them, the problem of the vicious circle can be solved, but only if they see through and learn to control it, it is too difficult.

Other people don't often come into contact with the organs, so they can't see it, the complexity of these organs is far beyond the current level on the Zhuling Continent, and it is really too difficult to see through, even if it is Guo Chen, it will take time.

But what they lack most now is time, no one knows what will happen in the trial land of Gangneung, but since it is the most difficult trial so far, they need to be prepared to spend time.

Judging from their current strength, there should be a year, and according to Gangneung's estimate, at most half a year later, another crystal will appear, and the mechanism must be closed before then.

Such a complex mechanism, let alone learning to control, even if you find a device to control the hole blocking, it is estimated that it will take a long time, and this learning to control will definitely not be possible in half a year.

But if there are structural drawings, it will be a different matter, but it is impossible, this site was not built by the Nightmare Clan, they don't even know who built it, where to find the drawings?

Jiang Ling had already told the others about the current situation, Shen Xuan and Ling Yunhao were also in deep thought, Jiang Xueyan had never looked away from Guo Chen, and Zhao Xue and Han Hao's expressions were a little weird.

After hesitating for a moment, Zhao Xue opened his mouth and asked, "Why can't we find something to block it ourselves?"
