"You know what that is?" Seeing Liu Yinyin's appearance, Fang Yan exclaimed.

Liu Yinyin was not in a hurry to answer, frowning slightly, and looked around carefully, as if she was looking for something.

On the stone wall above, a somewhat mysterious and not very clear pattern is artificially carved on it, the length and width of the pattern are less than half a zhang, if you don't look carefully, it is really difficult to detect.

The pattern looked a little complicated, and Fang Yan stared at it for a long time without seeing any reason. Fang Tingting is even more so.

Liu Yinyin looked around for a while, and then a look of amazement appeared on her face.

"What did you find?" Seeing this, the dialect that had been paying attention to the change in her expression knew that she had seen something, and asked anxiously, "Is there a way to go out on this?" ”

Liu Yinyin exhaled with some sighs and said, "I don't know if the pattern on this can let us out, but the pattern on it is very mysterious." ”

"Just say it, don't hang your appetite." Fang Yan said with a smile and a smile.

"I'm leaving...... I've seen patterns like this before. Liu Yinyin originally wanted to say that she had seen such a pattern when she left the sect, but she was afraid that Fang Tingting was here, so she still changed her words in time.

"This is a concealed formation, which can hide the things that are needed, and if you want these things to reappear, you need to close the formation according to the instructions of this formation. Coincidentally, the secret room where we store the formation spirit weapon is equipped with such a formation. ”

"Concealment formation?" Fang Yan was slightly startled, "You mean to say that this hall is not devoid of things, but that these things are hidden?" ”

Liu Yinyin nodded: "That's the case, but what exactly it hides here, and how much it hides, can only be known by closing the formation." ”

"Can the exit be hidden?" Fang Yan asked.

"As far as I know, it seems like everything can be hidden. But dead things like exits can't be hidden. ”

"So we still can't find an exit."

"It's not necessarily, maybe there is some mechanism here that we haven't noticed, and the method of opening this mechanism is very likely to be hidden by this senior."

Fang Yan was stunned, and asked a little blankly: "In other words, everything we see now is fake?" ”

"Nope." Liu Yinyin shook her head and said: "The concealment formation is different from the illusion, the illusion is to conjure up some fake things to deceive you, while the concealment formation method only hides some things, and everything else you can see is real." If we turn off the formation, these things will reappear in front of your eyes and mine, but what we see now will not change. ”

Fang Yan nodded thoughtfully, and said strangely: "This senior is really strange, why did he hide these things?" ”

"I said, this senior is very idle." Liu Yinyin also said with some tears and laughter: "It is precisely because he is too idle that he has come up with such ways to trick us." Just like this pattern, if we don't look closely, we don't know when we'll be able to notice it. ”

"Since this senior would do this, there should be other reasons, not just because he is bored." Fang Yan said with some solemnity.

Liu Yinyin spread her hands and did not refute, and seemed to agree with his guess. If Ziling is here at this moment, I'm afraid I'm going to scoff again.

"Can you close this concealed formation?" After a while, Fang Yan asked a little nervously, if she couldn't close it, I'm afraid she could really only wait until the disciples of the three major forces came. If that's the case, they won't have a head start.

"There is a method on it, and it is not difficult." Liu Yinyin smiled and pointed to it, and then walked forward, looking full of confidence.

Fang Yan glanced at her, and then looked at the pattern above with some confusion, but still didn't see anything. In desperation, he had to set his sights on Liu Yinyin.

Liu Yinyin walked to a stone wall, stretched out her hand and groped for a moment at a height of about half a zhang from the ground, and then pressed her palm slightly.

"Smack!"

After a crisp sound, there was an extra fist-sized hole in the stone wall.

Fang Yan was a little surprised, he was not surprised that he didn't notice anything unusual in that place. This hall is so large, it is not surprising that he did not notice anything unusual on this stone wall. He was surprised that the small hole did not look like Liu Yinyin had made it, but it looked like it already existed.

After finding this small hole, Liu Yinyin walked straight along the stone wall again, and after walking two feet away, she groped on the stone wall for a while, and then, another fist-sized square hole appeared on the stone wall.

Fang Yan watched this scene quietly, his eyes kept moving back and forth between the small holes and the pattern above, but even if there were two more small holes in this hall, there seemed to be no change in this hall.

Liu Yinyin walked along the stone wall in no hurry, and every time she walked two zhang, there would be an extra square hole the size of a fist on the stone wall. It didn't take long for there to be more than a dozen holes in the entire hall.

"......Huh" Half an hour later, Liu Yinyin breathed a long sigh of relief with some nervousness, and said to the two of them: "Be careful, open this hole again, this hidden formation will be closed, and the hidden things will appear in front of us." ”

"Is it dangerous?" Fang Yan asked.

Liu Yinyin shook her head and said, "I don't know, what is hidden by this senior may be a treasure or a crisis, do you think it should be closed now?" ”

"Naturally, the closure is going to be closed, but before it is closed, we have to take some precautions." Fang Yan said to Fang Tingting, and the two walked quickly to her, and then, a picture scroll spread out in midair.

Seeing this, Liu Yinyin couldn't help laughing, but she didn't say anything, and after getting the confirmation of the dialect, her palm sticking to the stone wall was slightly forced.

"Smack!"

After a crisp sound, another small hole appeared in the stone wall.

Almost at the same time as the voice sounded, the three of them disappeared into thin air.

In the scroll, as soon as the dialect stood still, he hurried towards the small hillside. Soon, the scene in the hall was clearly presented in front of his eyes. The rubble on the stone wall had just fallen.

In the center of the main hall, the space was slightly distorted, and a faint light rose out of thin air, and then gradually enlarged, and soon transformed into a square and sat on the ground, about one person tall and about half a zhang long. It looks like an energy shield, a square energy shield.

"What's that?" Fang Tingting exclaimed.

Fang Yan shook his head and cast an inquiring glance at Liu Yinyin.

Unexpectedly, Liu Yinyin also shook her head a little bitterly, and said: "I don't know what this is, looking at this appearance, there seems to be something in this light." ”

"Something?" Fang Yan was startled and looked at the light again, but this light was not transparent, and it was impossible to see what was inside.

He looked around, but the whole hall did not change except for the sudden extra square light in the middle. Looking at this appearance, this senior took so much effort to lay out such a formation, and he just wanted to hide this one thing.

"Go out and have a look?" Liu Yinyin asked.

Fang Yan thought for a moment and said, "Wait a little longer, who knows if anything will happen." If a terrifying monster beast escapes from this light, it will be troublesome. ”

Liu Yinyin smiled, and naturally she would not object out loud. After all, in this ancient tomb, it is better to be careful.

After the three of them waited in the painting scroll for more than half an hour, there was no change in the hall, the light that had turned into a square sat motionless on the ground, and the faint light emitted made the space slightly distorted, and other than that, there was no abnormality.

"Let's go out and have a look." Fang Yan took a deep breath and teleported out with the two of them.

"Have you ever seen anything like this?" Standing still in the main hall, Fang Yan asked aloud.

Fang Tingting smiled bitterly and shook her head, although she was a disciple of Qingyun Peak, she had been cultivating most of the time over the years, and she was basically cultivating in the same position, rarely touching things in the outside world, and where did she recognize this thing.

If Luo Ziyi was here, with her knowledge, she might be able to recognize it.

"I've never seen anything like it, but it looks like it's just a normal energy shield." Liu Yinyin said thoughtfully: "But what is it for, and why it appears here, is unknown." But there can be no doubt that there must be something inside this energy cover. ”

Fang Yan nodded thoughtfully, as if agreeing with her guess, after all, if there was nothing in it, it would be too much to say. But what he didn't dare to confirm was whether there was a way to leave this hall.

He looked at this light, and didn't know whether to step forward or not, and after hesitating for a long time, he still gritted his teeth and said to the two: "You wait for me here, I'll come forward and take a look." ”

With that, he took out the Ring Ancient Treasure and walked over cautiously.

The square light stood motionless, and there was no threat from it, but Rao was so, and the dialect did not dare to be careless.

Carefully circled around this strange light, and did not notice anything unusual.

Fang Yan stopped, looking at the light that was only half a foot away from him, and he had a feeling that he didn't know what to do. After a while, he seemed to have decided something, gritted his teeth fiercely, his palm moved slightly, and a stream of vitality energy gushed out in his palm, and then slowly amplified.

In the distance, Liu Yinyin and Fang Tingting, who saw this scene, also became solemn, and took out their spiritual weapons respectively, ready to take precautions.
