The space at the bottom of the Great Wall is very large, with a long corridor, the walls around it are very flat, it should be artificial, there are not many traces on the ground, it seems that no one has been here for a long time. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The brightness under the Great Wall was very small, almost none, and Ling Yiyun could only observe a little bit with the help of the sunlight shining in from the collapse above, otherwise with his current strength, he would not be able to see everything clearly in the dark.

"I mean, you're not going to explore here, are you?" Cao Zijian asked speechlessly.

"Isn't it exciting?" Song Cheng said excitedly.

Cao Zijian said helplessly, "Exciting, it's too exciting, I can't see anything, I really doubt that I will die if I walk all the way."

Hearing Cao Zijian say this, Song Cheng also thought of this problem, they didn't bring anything when they came out this time, just to play, how is this good.

"Who said they couldn't see it?" Ling Yiyun suddenly said on the side.

Everyone looked over when they heard his words, only to see the energy sword in Ling Yiyun's hand appear again, and suddenly the surroundings were much brighter, Yang Zinuo and Song Cheng understood in their hearts, and an energy sword appeared in both of their hands, and this time it became brighter.

Cao Zijian and Liu Meng watched with envy on the side, but their cultivation was too low to conjure up an energy sword, so they could only watch with envy on the side, only to know at this time that this energy sword could not only kill, but also illuminate.

"Let's go forward, to be honest, I'm also curious about this place," Ling Yiyun said to everyone.

Ling Yiyun walked alone in front, Liu Meng followed Yang Zinuo, and Cao Zijian followed Song Cheng, and everyone walked all the way down the corridor, and there was no abnormality in the middle.

"Why is this broken corridor so long," Cao Zijian muttered.

"Idiot, you, haven't heard of the Great Wall," Liu Meng said with disdain.

"I said can you not raise the bar with me, I didn't offend you," Cao Zijian said helplessly.

Liu Meng looked at Cao Zijian and thought about it, then nodded seriously, just when Cao Zijian wanted to say that it was about the same, he heard Liu Meng say "Can't"

"I... ! Cao Zijian said depressedly.

"What do you say? You're saying it again," Liu Meng glared and threatened.

"Don't quarrel, I've really convinced the two of you," Yang Zinuo also said speechlessly.

These two people are natural enemies, and when they meet together, they don't stop, and at this moment, Song Cheng let out a soft sigh, and everyone looked over.

"What's the situation?" Cao Zijian asked.

"It's okay, it's just wondering, how can this corridor be so long," Song Cheng said softly.

I didn't hear myself talking just now, which made Cao Zijian depressed, and Ling Yiyun and the others were also full of black lines, this head was really not an ordinary wooden one, and it was still slipping in this kind of place.

"Did you hear anything?" Song Cheng asked suddenly.

"Voice? What was that? Cao Zijian asked.

Ling Yiyun had already heard the voice just now, and he was listening carefully, but he was interrupted by Cao Zijian, and now he heard Song Cheng also heard the voice, and he was even more sure that he had heard it correctly just now, so he motioned for everyone to be quiet.

Ling Yiyun concentrated and quietly listened to the sound that came from somewhere, while the others also began to try to listen to what the sound was, but after listening for a long time, there was no result.

"No, it's too far away, it's still not audible, let's go ahead, everyone be careful" Ling Yiyun saw that he couldn't hear the result, so he said to everyone.

Everyone nodded when they heard this, and then followed Ling Yiyun forward little by little, but they all cheered up and continued to listen to the unknown voice as they walked.

"Stop"

Ling Yiyun suddenly said softly, just now he heard the voice clearly, although it was very small, but he heard it very clearly, it was actually the voice of talking, could it be that there are still people living underground?

"It's... Is this actually the voice of talking? It can't be a tomb robber, right? Cao Zijian asked in surprise.

"Have you watched too much TV, where does this place look like a tomb?" Liu Meng said with disdain.

"Who's talking then? Can't there be people living down here, right? Could it be a ghost? Cao Zijian said nervously.

"It's a person or a ghost, just look at it, you pay attention to your safety in a while, so as not to cause anything to happen, now we don't know the origin of the other party" Ling Yiyun said with a smile.

A few people walked slowly, and after walking for a while, they found that there was a bright light not far in front of them, and it seemed that they were about to reach the place, and at the end of the corridor, a scene came into view, which made several people very shocked.

That's too big, right? This space has to have tens of thousands of square meters, that is, a radius of ten kilometers, but I didn't expect there to be such a large space underground.

The strangest thing is that this space is not empty, but an ancient town, and the height of this space is also abnormal, it is actually hundreds of meters high.

There were some people walking back and forth in the town, but as if they didn't see Ling Yiyun and a few people, no one leaked a look of surprise, which made Ling Yiyun wonder, who were they?

"Why is this place so high? Isn't it the Great Wall up there? Song Cheng asked softly.

"There should be some distance from the Great Wall above, the corridor we just came, we feel that we have been walking on a parallel road, in fact, we have been walking down, we have been walking for so long, now it should be a place very deep underground" Ling Yiyun said lightly.

"It's strange here, are they all ancients?" Yang Zinuo came to Ling Yiyun's side and asked.

"I don't know very well, I just have to go over and ask," Ling Yiyun finished speaking and walked towards one of them.

"Excuse me, can I ask you what kind of place this is?" Ling Yiyun looked at a man in ancient costume and asked.

"This is not the place you should come, outsiders, just take a look if you are curious, but I advise you to leave quickly, and don't tell anyone about here," the man in ancient costume glanced at Ling Yiyun and said.

"Hey! You haven't told us what kind of place this is," Liu Meng said dissatisfiedly.

"Hey! Why do you outsiders ask that, knowing what kind of place this is that is not good for you, you better get out of here," the man sighed.

Ling Yiyun stopped Liu Meng, who wanted to speak, if she was asked to continue, she wouldn't ask anything, seeing that Ling Yiyun didn't let herself speak, Liu Meng could only run to Yang Zinuo's side depressedly and pouted with a look of displeasure.

"Please tell us, otherwise we may be curious and refuse to leave," Ling Yiyun asked with a smile.

"Hey! Let me tell you, this is the Land of Oblivion," the man replied helplessly.

"The Forgotten Lands?" Everyone asked.
