Surprisingly, the sewer is not a food processing factory, but a metal promenade, and the lights on both sides of the passage are bright but not dazzling, and it looks a bit high-tech.

"Judging from the trend of the sewer before, this should be the underground of the food processing factory, which is quite hidden!" Aolong exclaimed. "Is it hidden? It's not like you've found it easily. Yang Jian complained weakly. Is this the same? Anything, as long as the Immortal Seeking Academy is willing to explore, there is no secret to speak of. ”

The dragon closed his eyes, sensed it, and said, "Spirit breath...... It should be on the left. Yang Jian looked at the wall to the left of Aolong and said, "Are you sure?" There's no road on the left. "The passage is only in the front and back directions, and the rest of the place is full of metal walls.

"Let's go, let's go to the front first." Auron said, walking forward. Yang Jian followed, looking behind him from time to time, and for some reason, there was not even a person here.

After walking for a while, there was an intersection in front of him, and after Aolong observed it, and after finding that there was no one, he took Yang Jian into the corridor on the left. Sensing the aura of the stone beast's spirit, the dragon went all the way forward, passing through many forks in the road.

"These are like a labyrinth, each passage does not lead directly to the stone beast spirit, although I have always sensed its presence, but no matter how I walk, I can't get close to it, if I can't locate it through induction, maybe it will go farther and farther." Aolong stopped and said with a frown. "No wonder there's no one guarding here, it's a powerful defense." Yang Jian also figured out why there was no one here.

"Lingshui, record the route of travel." The dragon spoke, and the earrings emitted a light that projected a point of light. "As long as we walk a few more corridors, the earrings will draw a route map for us to walk, and then we will be able to position ourselves more accurately according to the route map." It only took a moment for Auron to think of a way.

Yang Jian leaned on the metal wall and followed behind Aolong, looking at some cameras at the fork in the road, and couldn't help but think: There is no one here but there are a lot of monitoring equipment, if Zhenruo hadn't been invaded, the two would have been discovered a long time ago.

"By the way, I don't know what's behind the metal wall, why don't you try to break through the wall and go straight in the direction of the stone beast spirit?" A flash of inspiration flashed in Yang Jian's mind. "Maybe it's dirt, maybe it's another corridor, but whatever it is, we can only go along the corridor, and for some reason, the walls here are very hard and very difficult to break." Aolong shook his head and said.

"Oh." Yang Jian replied in disappointment, it turned out that Aolong had thought of it a long time ago, and he also knew that this wall could not be destroyed, and his IQ was still a little insufficient compared to these real human elites.

"Don't be discouraged, since it's a labyrinth, there must be an exit, otherwise there won't be lights and cameras here." Aolong comforted Yang Jian and said. "Huh?" Yang Jian suddenly felt that the wall he pressed felt different from before, as if it was much softer, and he couldn't help but press it hard, trying to determine if it was his illusion.

Suddenly, the wall in front of him flipped over, and Yang Jian did not stand firmly, and was taken to the other side of the wall.

This is also a long corridor that is the same, Yang Jian turned his head and pushed the wall, but the wall did not move at all. "Can you hear you?" Yang Jian shouted. "Can you hear me...... Can you hear me...... See...... ......" Yang Jian's echo filled the hallway, but none of the dragon's voice reached Yang Jian's ears.

Yang Jian searched for a while, but he didn't find a mechanism that could turn the wall, and the previous button was also invalid. Yang Jian took out the jade trick and wanted to see if he could destroy the wall, but in half a day, he only left a few sword marks on the wall, and it was impossible to get through. Yang Jian could only hope that Auron would be able to discover the other mechanisms.

After waiting for a while, looking at the corridor that had not changed, Yang Jian also knew that he had to rely on himself next.

Thinking of Aolong's earrings, Yang Jian didn't know if Zhenruo could help him record his whereabouts. "Zhenruo, come out." Yang Jian took out his mobile phone and called a few times, but Zhenruo didn't appear.

Yang Jian had a bad premonition, and clicked on the word "prison" icon, Zhenruo appeared, but his eyes were hollow, looking like a model of a person without any intelligence. "Zhenruo, what's wrong with you?" Yang Jian was a little anxious, worried that something had happened to Zhenruo.

"The network connection fails, the carrier is not enough to provide the calculation, and it automatically exits after five seconds." Zhenruo said sluggishly. Yang Jian found that the mobile phone has no signal and no network here, and it should be that it cannot be connected to the central intelligence. "So, how did the Auron earrings connect to the spiritual water?" Yang Jian thought for a while, could it be the built-in function of the earrings.

Thinking of this, Yang Jian really wanted to drop the Apple phone in his hand to the ground, kick it twice, and kick it away with the last kick, "What garbage!" Yang Jian finally knew why Zhenruo would say that his mobile phone was garbage, and it was okay for ordinary people to use it, but it obviously couldn't meet the needs of cultivators. Look at the earrings of Aolong, they are small in size, multi-functional, and even a small computer in themselves, even if they can't connect to the main body, they can have their own intelligence, and their own computing power must be very powerful.

Yang Jian could only grope by himself, and every time he walked to an intersection, he left a mark on the wall, although he couldn't break the wall, it was still easy to leave a little trace. However, Yang Jian walked for nearly an hour and did not encounter the intersection where he left a mark. In other words, this labyrinth may be very large, and Yang Jian has never returned to the path he originally walked.

"Zhenruo said that they are reading the video materials here, and they don't know if they succeeded, but even if they succeeded, they couldn't contact them, and it was useless." Yang Jian thought as he walked, "By the way, since they control the surveillance here, does that mean they can see themselves?" ”

Yang Jian moved forward quickly, and after a while, he came across a crossroads. Raised his head, looked at the camera in the center of the intersection, and said, "Zhenruo, Heimo, can you see me?" After Yang Jian finished speaking, he saw the camera shaking his head left and right. ”

"Can't you see?" As soon as Yang Jian finished speaking, he covered his mouth. Looking at this camera that could only rotate left and right, Yang Jian could imagine that Zhenruo and Heimo must be yelling there: "You stupid, do you look at this camera as if it can nod?" ”

However, if the camera reacts, it means that if they can see themselves, "Can you tell me which way I should go?" After Yang Jian asked, the camera began to rotate, and finally pointed to the corridor on the left. Got it, thanks. ”

Under the guidance of the camera, Yang Jian walked for another half an hour and passed several forks in the road.

"Zhenruo, which way should I go?" Arriving at another intersection, Yang Jian questioned Zhenruo again, but found that the camera kept pointing to the way he came. "Could it be that you let yourself go back the way you came, it can't be that you pointed the wrong way before?" Yang Jian thought about it, but quickly denied it, in this kind of big thing, with Zhenruo's calculation ability, there should be no such problem as mistakes, and there is also black ink on the side to help.

"At the last intersection, the correct road is in this direction, but at this intersection, the correct road is the direction from which it came, can it be said that the real road is between these two intersections?" Yang Jian touched his chin. "Could it be that there is a mechanism in this corridor? If so, rotate it in the direction of my right hand. This is the only possibility that Yang Jian can think of, seeing the camera rotating to the right, Yang Jian smiled, ran to the camera, and bared his teeth at the camera: "I'm really a genius." The camera turned the "face" to the side very cooperatively, obviously not wanting to see Yang Jian's face.

Yang Jian also entertained himself and relaxed. Staying alone in this kind of corridor, although the lights are bright, but after a long time, it will still give people a feeling of fear, especially when there is no way out, and there may be psychological problems.

Yang Jian just wants to leave this oppressive place now, walking in the corridor, there is always an illusion that someone is following behind him, just like walking in the dark, always feeling that there will be something looking at you in the shadows.

After more than ten minutes of searching, Yang Jian finally found the mechanism, and although he was prepared, he was still brought over.

Sure enough, there was an identical corridor in the back. Yang Jian was not too disappointed, with Zhenruo's help, it would be a matter of time before he went out.

Time passed minute by minute, Yang Jian sat down weakly, looked at the time, and it was almost twelve o'clock.

"Hey, how far is it?" Looking at the camera not far away, Yang Jian said weakly. This is just a stronghold of the Demon Sect, how can it be so big, and this time it is just a defensive labyrinth outside, the Demon Sect is too rich.

"It's coming, it's almost time to get to the exit." The sudden sound startled Yang Jian. "Who, who's talking? Come out. Yang Jian jumped up in shock, holding the jade trick in his hand, and did a good job of defense.

"Are you a pig and can't even hear my voice?" The voice echoed through the hallway again. Yang Jian heard the source of the sound this time - the camera.

"Black ink? What's the situation? Yang Jian breathed a sigh of relief. Maybe because this is almost to the exit of the maze, so the installed camera should also be a little more advanced, with its own speaker! "I said this maze is too big, the demon cult is really a local tyrant, and I don't know what metal is used to create such a big maze, but thanks to its local tyrants, surveillance cameras are installed at every intersection, otherwise it really can't get out." Yang Jian didn't know what to say about this demon sect anymore.

"Actually, the diameter of this labyrinth is less than a thousand meters, and the central area is the real stronghold of the demon clan, so, in fact, it is not big." Black Ink's voice came from the camera. "What? Just kidding, I've been walking for hours, you can't be playing with me on purpose, are you? Yang Jian said, gritting his teeth and looking at the camera.

"Do you think I'm so bored that I'm going to joke about something like this? This labyrinth is built with gossip as the blueprint, and it itself has the function of influencing people's sense of direction, plus the design of a hidden passage, there are no dead ends and the like, all the corridors are connected together, ordinary people can't get out at all, and cultivators will be affected by the formation. Heimo said disdainfully, showing that he was despising Yang Jian, an illiterate person.

"But since you know the map, can't you just go out?" Yang Jian still doesn't understand. "Actually, the maze is not constantly changing, you have to walk a certain route to get out, but you can't feel it. Moreover, the wall comes with a memory function, and the prototype can be restored under natural conditions, okay, I won't talk to you more, let's leave when you're resting, and you can go out as long as you go through a dark passage. Heimo didn't want to explain more, urging Yang Jian to act.

"What's going on there, is there any danger?" Yang Jian stood up, trying to figure out the situation inside and get ready. "Won't you know when you go in?" Heimo didn't answer Yang Jian's question.

"Okay." If Heimo doesn't say it, Yang Jian can't help it, but there shouldn't be any danger, after all, it's impossible for Heimo to harm himself. Actually, what Yang Jian didn't know was that what Heimo was thinking at this time: Hmph, let you not believe me, don't give you a lesson and don't know how to respect my sister.

Yang Jian found the mechanism and walked through the wall, but then, Yang Jian was stunned......
