Once agreed, Mo Xuan and the Ten Concubines chose a pit not far from one side, and seeing that the pit was not deep, the two jumped directly into it without pausing.

The pit is only a few meters deep, and standing at the bottom of the pit, it is pitch black, and it is impossible to see the surrounding environment at all, only a bowl of light before night is above the head.

The tenth concubine took out the luminous stone, and in this faint light, she could see the surrounding situation.

In the east and west directions of the bottom of the pit, there is a two-meter-high tunnel, which stretches out into the far and dark front, and I don't know where the end is, and I don't know if there is any living creature in it.

Looking at the dark corridor, Mo Xuan couldn't help but feel a little scared in his heart, but because the tenth concubine was here, he couldn't say what he thought in his heart, so he could only forcibly suppress his palpitations and observe the surroundings with a hard head.

"This is a desert, theoretically there shouldn't be such a standard Yongdao, it seems that it should be built by man, and the scope of this ghost pit is so large, it seems that the people who built this Yongdao back then also made a lot of effort. Looking at this corridor with fluorescent fluorescence, the tenth concubine said softly.

Mo Xuan also saw the special nature of this underground corridor, reached out and touched the extremely flat wall, and asked curiously: "But what did that person do with so much effort to build this corridor? Even if it is to facilitate the theft of treasures in Dancheng, then it doesn't have to be built so neatly." ”

Hearing this, the tenth concubine also shook her head for a while and said, "I don't know, but since that person is willing to spend so much effort to build the Yongdao, then there must be something here that is worth making him do." ”

"Then let's take a look inside, I'm curious about this place. Mo Xuan urged, and when he arrived, he was full of curiosity, but he was not so afraid.

"Hmm. The tenth concubine nodded, took out another luminous stone, and handed it to Mo Xuan, and the two of them walked one after the other, with the help of soft fluorescence, towards the depths of the internal corridor.

The underground passage is extremely smooth without a trace of potholes. The two of them went inside along the corridor and were on guard. But after walking for half an hour, the two of them didn't know that they had walked a short distance, but they still couldn't find the end.

"How deep is this tunnel, it can't be a labyrinth. "Vigilant all the way, Mo Xuan said secretly.

The tenth concubine was also curious, and said: "It's indeed a little strange, but no, the road built in such a remote desert shouldn't be so long." ”

Mo Xuan thought for a moment, stopped moving forward, looked at the tenth concubine, and asked, "How long have we been in?"

"It's been almost half an hour, what's wrong?" the tenth concubine asked curiously.

Mo Xuan said analytically: "Something is not right, although we have been walking relatively slowly during this time, but with our foot strength, we have walked two or three miles, such a length of Yongdao, there should be some forks." ”

"It's really wrong, so let's retreat the same way first?" As a woman, the tenth concubine chose to discuss with Mo Xuan at this time.

"Since you're down, how can you go back so casually. And one thing you didn't notice, we saw a lot of potholes outside before, and those pits should be able to enter this corridor, but after so long, we haven't seen a passage to connect with the outside world. Mo Xuan said.

"What do you mean? Are you saying that the holes outside are not connected to the same corridor?"

"Maybe, but I don't think the people who built this tunnel should have the financial resources to build different tunnels, and those potholes may be connected to the corridor we are on, but we haven't found it. Mo Xuan said.

The tenth concubine asked suspiciously, "What do you mean?"

Mo Xuan smiled, patted the wall of this corridor, and said: "Seeing is not necessarily believing, there may be some famous halls under this corridor." ”

"What?" the tenth concubine was puzzled.

Mo Xuan stretched out his hand, palm facing upward, and the source qi of his five fingertips slowly converged. "I've heard people say that in some strange places, the owners of the places always put up some strange barriers to prevent outsiders from entering, and although they may not be a threat, they can keep most of the intruders away. ”

"Obstruction?" As soon as the tenth concubine heard this, she also instantly understood, and said, "Do you mean, is there something like a psychedelic formation set up here?"

Mo Xuan nodded and said, "That's right, this place is located in the desert, and the earth attribute is extremely strong, and I should set up an illusion here, which should be the easiest means." ”

"Then can you crack it?" asked the tenth concubine.

"I don't know, but let's try. ”

Mo Xuan said, the gathered source qi on his fingertips was slowly transforming, under his control, he saw that the source qi continued to rotate and form, and in the blink of an eye, the five runes of Qian, Gen, Kan, Li, and Xun were directly condensed.

The thumb is the main, and the knot is replaced by the four fingers, and the four fingers are in the position of the five elements, respectively, with the four symbols of Kan, Li, Qian, and Xun.

"The Seal of the Earth. ”

With a drink in his heart, the sigil slowly rotated, and under the heterochromatic gaze of the tenth concubine, it directly turned into a light array, and the light array flickered slightly, not with a buzzing sound.

As soon as the light array was formed, Mo Xuan mobilized the source qi and poured it into the light array, and the light array expanded instantly, turning into a formation disk the size of a meter.

"Seal!"

Airplanes.

After the seal was struck, a slight shaking sound suddenly came from the corridor, and Mo Xuan and the others felt a misery in front of them, and in an instant, the originally unobstructed corridor in front of them instantly turned into an underground labyrinth with countless branches like an ant's nest.

"It's an illusion, but it's a basic illusion. Seeing that this illusion maze was broken, Mo Xuan was also secretly relieved.

The tenth concubine smiled appreciatively, swept her eyes around, the smile on her face slowly disappeared, and asked, "How can there be so many forks in the road here? Is this an illusion?"

Mo Xuan looked carefully, and then shook his head and said: "It shouldn't be, but we have to be careful, since there is an illusion maze arranged outside, then the master must want to hide the things inside, although I don't know if it's good or bad, but I think there should be other traps inside." ”

"Hmm. The tenth concubine nodded, glanced at the fork, and asked, "There are so many forks here, they should also be used by psychedelics, can you tell which one leads to the front?"

Mo Xuan shook his head and said: "I don't understand the identification of directions, this is what Brother Xiaosan is good at, and he knew that they both came." ”

"It's useless to say that, look at me. As he spoke, the source qi instantly wrapped around the ten concubines, and a source qi rosette gathered under him, and the lotus was suspended out of thin air, and the ten concubines took advantage of the situation to sit cross-legged.

The tenth concubine's hand made Mo Xuan stunned, and at the same time, she was secretly thinking in her heart, what kind of strength she was, such a powerful source qi manipulation power, it was not like an ordinary martial artist could do it.

The ten concubines sat on the lotus seat in the air, the imprints between the ten fingers were constantly changing, only to see the source qi around her body flickering like breathing, and under her control, the source qi overflowing around her body was constantly changing, and in an instant, hundreds of small hummingbirds condensed by the source qi appeared out of thin air.

"What is this?" Looking at the dense flock of source qi hummingbirds that suddenly appeared in front of him, Mo Xuan couldn't help but be a little stunned, he couldn't figure out what the tenth concubine was doing with these hummingbirds.

"Yu!" The ten concubines moved their small mouths, and the knots between their fingers changed rapidly, only to see that the hundreds of hummingbirds were neatly lined up, their wings flapping slightly, and they couldn't help but have a moment of beauty when they glanced at it.

"Go!" Controlling the hundreds of hummingbirds, the handprints of the ten concubines changed again, only to see the hummingbird instantly flutter its wings and fly high, heading straight to the inside of the road, and every time it encountered a fork, three or five hummingbirds broke away from the team and flew towards the inside of the fork.

Seeing the move of the tenth concubine, Mo Xuan praised it, this method is indeed efficient, far from being humanly attainable.

The tenth concubine sat firmly on the source qi lotus, and Mo Xuan guarded the side, waiting quietly. The tenth concubine pinched the seal knot, and after about a quarter of an hour, her closed eyes slowly opened, with a little doubt in her eyes.

"Did you find the entrance?" Mo Xuan asked, for this kind of underground labyrinth, he was not in the mood to search slowly, so he had to ask the tenth concubine.

The tenth concubine glanced at Mo Xuan, dispersed the source qi lotus, and said: "I found it, but there are two passages in this corridor that can enter the underground, and I don't know which one is the real entrance." ”

"Two entrances?" Mo Xuan was also puzzled and asked, "Is there any difference between these two entrances?"

"The difference is nothing, one is south and one is north. It's just that the passage to the south seems to be in some obstacle, and the hummingbird can't go down, but the entrance to the north is all the way open. The tenth concubine said.

"Then how do we go next, should we go to the south, or to the north?" Mo Xuan asked.

The tenth concubine thought for a while and said, "Since the passage to the south is blocked, then let's enter through the entrance to the north, and if we can't find anything, we will come back." ”

"Well, so be it. Mo Xuan nodded.

As she spoke, the tenth concubine took the lead and followed the path she had explored earlier, heading towards the end of the passage to the north. Mo Xuan followed, constantly looking.

The two of them walked cautiously all the way, the pace was not so fast, and after turning left and right in general, they walked for about half an hour, and then they came to the entrance that the tenth concubine said.

Standing at the end of the road, with the light of the luminous stone, Mo Xuan could clearly see that there was a stone staircase leading to the ground in front of him, and the steps were covered with moss, which made Mo Xuan and the others strange, after all, in this desert area, there was still such a thing.

The two glanced at each other, and after nodding slightly, Mo Xuan threw the luminous stone in his hand into the dark underground space, only to hear a snap, the luminous stone fell to the ground, and the two took a look, the light was not far away, and the underground space was not too deep, so Mo Xuan took the lead and stepped on the moss steps, walked down the entrance, and walked towards the underground space. The tenth concubine followed, and at the same time took out two luminous stones from her arms.

Click!

The two of them walked one after the other, and the footsteps tower was on the stone steps, and the crisp sound lingered in this silent underground space for a long time.

"It's quite empty here, can you tell that this is Dancheng?" Hearing the echo of footsteps here, Mo Xuan asked, although his voice was soft, but the echo was also lingering in this empty underground space for a long time.

The tenth concubine shook her head and said, "I can't see it, but there is a lot of space here, and the walls are very high, but it looks like an ancient city swallowed up by the desert." ”

"If it's really a castle, then it's likely to be where Dancheng is located. Have you ever known about Dancheng, and where is the area we are in now?" Mo Xuan asked.

As they spoke, the two of them had already walked down the steps and touched the ground of the underground space, which was covered with fine sand and was extremely soft. The tenth concubine walked to the wall and walked up along the wall, and found a stone lampstand.

Mo Xuan also saw that the two of them lit the stone lamps one by one, and after a while, the lights illuminated this underground space, and the two of them also saw the scene in front of them very clearly.

This place is indeed a part of the city, and there is a city gate not far away, and it is thought that this place should be one of the four gates of Dancheng in those years. This city wall is about ten zhang high, and the wall above it is still faintly visible, and the mossy steps that the two of them came down just now are the steps used to climb the city wall.

"Looking at the style, there is no doubt that this place is indeed the Dancheng of the year. And this place is located in the north, and there is a city gate not far away, and it seems that our location should be the north gate of Dancheng. Looking around, the tenth concubine whispered, and at the same time, her footsteps slowly walked towards the city gate.

Mo Xuan followed closely, scanning the surrounding situation and said, "If this is the north gate of Dan City, then let's go south, there should be something to be found in the main city." ”

The tenth concubine nodded and said, "Well, there should be something in the main city, but don't you think it's a little strange, Liqing said that there are ghosts here, although I know that the 'ghosts' she said must be other living creatures, but we have been down for so long, why haven't we heard any movement of living creatures?"

Hearing what the tenth concubine said, Mo Xuan was also strange, and he looked around, and then said: "Maybe it's because this is the edge of Dan City, you should be able to find something if you go inside." ”

"Well, let's go, but be careful, and if there's any unusual movement, we'll retreat. The tenth concubine said.

"Well, I understand. Mo Xuan nodded.

After saying that, the two of them walked towards the interior of Dancheng one after the other, just in case, both of them carried the source qi protective body, and walked forward cautiously.
