Therefore, Nangong Yu can't be sure whether the texture that has changed now is the original pattern.

Nangong Yu's brows furrowed, looking at the lines on the stone wall in front of him, his eyes deepened.

"Damn it!"

Blame him for being careless!

Originally, he thought that the changing stone wall was a sign of going out, and when he had been staring at it and there was nothing abnormal, he should have known that this pattern was not a way to get out, but a link in the method!

It's just that Nangong Yu knows too late now, and he has missed the best time to look at it!

"It's okay, it's not too late......"

Nangong Yu whispered.

Fortunately, he had just stared at that pattern for a long time, and he had already recorded all of it!

In order not to miss the opportunity again, Nangong Yu immediately used his spiritual power to draw the pattern in the air, and cast a small spell so that the drawn pattern could be kept there forever.

"Ah Yu, what do you mean by that?"

Du Yutian felt a little strange about what he did.

She had just come down, and she didn't know what Nangong Yu had experienced and done before, and now she asked a little strangely when she saw Nangong Yu's approach.

Nangong Yu patiently replied: "The texture of the stone wall in this place 3 will change, so I want to record those changing textures, maybe I can find out some rules from this, so that I may be able to get out!" ”

"That's what it looks like!"

Du Yutian suddenly realized.

This place is easy to get in and out of at first glance, but even in difficult places, there are ways to get out.

Just like her master Ling Xi said, there are no difficult formations in the world, because no matter how difficult the formations are, their cracking methods are often the most unexpected and easiest way.

Therefore, Du Yutian firmly believes that they will definitely be able to get out of this broken place, it is only a matter of time.

Because the moment she came in and saw Nangong Yu, you understood.

The purpose of setting up such a place in this secret realm is just to train them.

After all, if this secret realm was going to kill them, then it would be good to drag them into this place and kill them here with a powerful spirit beast or something.

It's not.

On the contrary, they have set up such a somewhat simple method.

Presumably, this secret realm set up such a level just to embarrass them for a while, and did not think of any way to really hurt them.

Thinking about it like this, Du Yutian's nerves, which were still a little nervous, were completely relaxed at this moment.

In that case, they must be able to find a way out.

It's just that, although they will definitely be able to find it, they will have to investigate it carefully and carefully.

After all, this secret realm was already very kind to them, so it would not send the answer to them.

Presumably, there won't be any hints on how to get out after that.

And now, for them, the changing patterns on the stone wall have become their only clue now.

So, you must be cautious and cautious!

"In that case, let's take a look! See if you can find any patterns or clues. ”

Du Yutian looked at Nangong Yu and said with a smile.

Nangong Yu also replied with a smile: "Okay, let's take a look together." ”

After speaking, the two of them immediately came to the stone wall, Du Yutian was responsible for recording the time, and Nangong Yu was like the first time, taking it seriously, and carefully checking the lines on the stone wall.

Nangong Yu walked along the lines with his fingers over and over again, but there was still no change, the same as the first time.

Nangong Yu was a little deflated, but quickly calmed down.

Nangong Yu stood up suddenly, condensed his spiritual power and drew an exact one according to the lines on the wall, the same as the first one drawn, Nangong Yu also saved them, in order to prevent it from disappearing, Nangong Yu used a secret method to preserve, so nothing was discovered.

Since this pattern doesn't seem to know what it does to the touch1, let's record it first, so as not to forget what it looks like in the end.

And Du Yutian also began to record the time minute by minute at this moment.

Nangong Yu checked the texture of the stone wall many times during this time, but still found nothing.

However, it is much faster and easier for two people to do things than for one person, and Nangong Yu does not need to maintain such a strong sense of vigilance, for fear of encountering any danger or something.

This time the texture took half an hour to change, and then it became another pattern, another pattern that had never been seen before!

Nangong Yu and Du Yutian glanced at each other, and they both saw a clear look in each other's eyes.

It was now clear to them that the texture changes in this place are different, not just two lines, but several lines changing alternately.

There's a whole new pattern.

Nangong Yu and Du Yutian followed the method of the two of them at the beginning, Nangong Yu was responsible for checking the records, and Du Yutian was responsible for recording the time.

Nangong Yu looked at it carefully as if he had checked the last two lines, and there was still no difference.

Even though he has seen this pattern many times, Nangong Yu still wants to give it a try.

After all, what if an accident happens?

These years of experience tell Nangong Yu that he must not let go of any clues and differences.

Even though the first two changes in the lines made Nangong Yu, who was actively looking, not see anything, he still took a serious look at it.

Because Nangong Yu doesn't want to let go of any opportunity, anything different.

He was afraid that there would be no chance to go out and take a look, so he didn't dare to relax for a quarter of an hour, and kept looking for loopholes.

Du Yutian counted the time, Nangong Yu looked for loopholes, time passed minute by minute, and the cooperation between the two people was very tacit, so time passed very quickly, and before he could react, the lines on the wall began to change again!

Du Yutian silently calculated, and this time it took nearly an hour. I love to read

Then, after nearly an hour, a new pattern appeared.

And Nangong Yu also immediately stepped forward to check the changed texture.

"This pattern, it seems that I have seen it somewhere. Oh-" Nangong Yu racked his brains to think about something, and finally remembered, this pattern was not the one he saw at the beginning! ”

So there are four patterns of change, and now it's time to look for changes between them!

Nangong Yu looked at the fiery red lines in the air, looking at the similar lines, and felt that his brain was not enough.

How do you find this?

This kind of texture doesn't seem to be special at all, it just feels like an ordinary pattern, but the texture is different because it's in the same place.

Nangong Yu felt a little dizzy when he thought about this, what should he do?!

You can't just watch it all the time! It doesn't seem to be useful at all!

Just when Nangong Yu and Du Yutian were checking the difference in the textures, the textures changed again.

Nangong Yu walked over to check.

The lines on the stone wall have become the lines that I saw secondly.

Therefore, Nangong Yu was also convinced of his speculation and thoughts.

This is really the four lines that are constantly changing and changing.

It's just that Nangong Yu knows the appearance of these four lines, and also knows how often they change between them.

It's just that Nangong Yu quickly discovered that knowing these is useless at all!

Knowing these can't help him crack the secrets of these lines, he still doesn't know how to get out!

As soon as he thought of this, Nangong Yu became depressed.

He knows what's the use of this, doesn't he still know how to get out?!

Nangong Yu was very depressed at the moment, and he really wanted to give up the idea of going out.

There's no danger in here anyway, and it's not impossible to stay for a few days.

Nangong Yu sat on the ground sullenly.

After all, he's wasted a lot of time trying to do this!

It made him almost blind, and the whole person was not good, so he finally got it out. It turned out that these things were of no use at all!

Nangong Yu said: "......"

Life is hard!

He's really hard!

Nangong Yu decided, if he went out, he would definitely suggest that Mo Ling let him dismantle this secret realm!

It's useless, it's so infuriating, why keep it!

Nangong Yu silently hid in the corner and drew a cursed circle.

This secret realm is really a knack!

Du Yutian was a little helpless when she saw him like this.

Why is this guy so breathless, it's only been a long time, and he can't stand it.

Du Yutian has been learning the art of formation with Ling Xi these days, and the first thing he has cultivated is patience.

After all, formation is not just a matter of talent, hard work is also very important.

When cracking a formation, the most important thing is to be very careful and be able to observe any differences in the formation.

Patience is also the most important.

After all, if a formation is too difficult to crack, it will require the cracker to stay in it for more than ten or twenty days.

At this time, there will only be one person left in the formation.

Therefore, in this case, it is easy for a person's nervous breakdown to lead to a series of events that cannot be dispensed with.

And if this person had enough patience, he would have been looking for a way to crack it for so long.

Not only that, but if a person has a lot of patience, then he will do everything with half the effort.

Because he doesn't do anything excessive or go astray because he's in a hurry.

On the contrary, he will succeed because of his patience.

These were all realized by Du Yutian when he was cultivating the way of formation.

Du Yutian thinks that these things are very effective.

It's just that patience is very little left for Nangong Yu, a person who is already anxious and has not been trapped.

So Nangong Yu can also be said to be a person who has almost no patience.

If there is, it won't be unbearable for only a day or two.

Du Yutian's cultivation these days can be said to have helped her to be reborn and grow rapidly.

Du Yutian encountered a bottleneck when she was cultivating the formation before, and in order to help her break through the bottleneck, Ling Xi deliberately set up a formation with a very high difficulty coefficient and locked Du Yutian in it to exercise well.

At that time, Du Yutian could be said to have stayed in it for a full ten days.

And there are no people in this formation, not even trees and animals, it is just a barren land, and there is only Du Yutian alone.

The first two days when Du Yutian first entered was like Nangong Yu now, and the whole person was very depressed.

Every day is faced with a barrenness, Du Yutian can be said to collapse and explode as long as he thinks that there is only one living creature in this formation, and the whole person is on the verge of madness.

But in the next four or five days, Du Yutian found that no matter how crazy she was, she still couldn't get out.
