Nangong Xuan discovered something that he had never discovered before, this nine-square grid is not static, and the layout inside will change.

This also made him understand why every time he followed a route just now, the situation he encountered was different.

Even if you follow a different route, this will still happen.

Nangong Xuan returned to the entrance, this time he did not walk in a hurry, but stood at the entrance, carefully recalling the layout of the nine-square grid.

The nine-square grid is the horizontal nine, the vertical nine, and the intersection is still the order of nine.

This means that the nine-square grid is changeable, and there are at least twenty-seven variations.

In Nangong Xuan's view, there are definitely more than twenty-seven changes in the nine-square grid, that is to say, twenty-seven is just the basic change of the nine-square grid, and there will be more complex changes in the future.

However, these are not the problems he has to consider now, he only needs to calculate the twenty-seven changes of the nine qualified foundations now.

It's just that if you want to figure out these 27 changes, it's not difficult to say it's easy, and it's not easy to say it's simple.

Taking a deep breath, Nangong Xuan began to act again.

Since he wants to count, he must mark it in the nine-square grid so that he can use it for counting.

Seeing Nangong Xuan move again, Ma Zhong and Ma Lingling's expressions moved.

Seeing Nangong Xuan standing there motionless just now, they were really afraid that Nangong Xuan would give up.

Ma Lingling frowned: "What kind of principle is the Prison Heaven Seal of your Great Yan Dynasty, and why is it so difficult, even I can't see all the changes."

Ma Zhong smiled bitterly: "How do I know, I also tried to cultivate at the beginning, but I still didn't succeed."

It was too difficult to imprison the Heavenly Seal, and he didn't know where the ancestor of their Great Yan Dynasty got this secret technique back then.

I don't know how their ancestors, as well as those ancestors, learned the Prison Heaven Seal.

While Ma Zhong and Ma Lingling were speaking, Nangong Xuan took a few more steps, but quickly retreated back to the same place.

After a slight pause, Nangong Xuan raised his feet and walked forward again, this time farther than the previous ones, but he still couldn't get out of the Nine Palaces.

Nangong Xuan returned to the same place, this time he did not continue to move forward, but slowly closed his eyes.

He has counted all the nine-square grids, which are eighty-one small grids, condensed into a whole nine-square grid.

It's just that before, because the nine-square grid was often changing, he didn't know what area he was in, but now it's okay, each grid has a number he marked, and this time he is not afraid of chaos.

Nangong Xuan took a deep breath and raised his feet to move, he believed that this time, he would definitely be able to succeed.

As it deepened, the nine-square grid also began to change, but at this moment, Nangong Xuan had formed a mini nine-square grid in his mind.

Every time the nine-square grid changes, the nine-square grid in his mind will change with it.

Nangong Xuan walked very slowly this time, and every step seemed to be calculated.

Outside, Ma Zhong and Ma Lingling saw this scene, and immediately became nervous, they wanted success more than Nangong Xuan.

Once Nangong Xuan succeeded, they would be freed and would no longer have to be trapped here.

Of course, the most excited is Ma Lingling, Ma Zhong is just a remnant soul, and his so-called liberation is to disappear.

But she is different, her liberation is unrestrained, and from now on, the world is big.

Under the nervous gaze of Ma Zhong and Ma Lingling, Nangong Xuan had already walked forty steps.

When he walked fifty steps to the ground, Nangong Xuanyi accidentally made a mistake and was stopped again.

Helpless, Nangong Xuan could only return to the starting point.

Ma Zhong and Ma Lingling all showed regretful expressions when they saw this scene, they had already come here, and if they persisted for a while, they would be able to succeed, but they didn't expect to fail.

After that, Nangong Xuan tried alone, but the result was still that there would be mistakes in the back, which made him very puzzled.

It's impossible to be wrong in your own calculations, so what is wrong?

Nangong Xuan looked at the nine-square grid in front of him again, and at the same time, he kept recalling the changes in the nine-square grid in his mind.

After thinking about it for a long time, Nangong Xuan felt that maybe he was too anxious, before he just made a count, he started to act, this time he had to calculate twenty-seven basic changes.

Seeing Nangong Xuan squatting on the ground, motionless, Ma Zhong and Ma Lingling couldn't help but be a little anxious, but there was nothing they could do, they couldn't help at all at this time.

Time passed inadvertently, and I don't know how long it was, Nangong Xuan finally stood up from the ground.

But he didn't start directly, maybe he was rehearsing.

didn't let Ma Zhong and Ma Lingling wait too long, and after a while, Nangong Xuan finally took a step.

Nangong Xuan's speed of progress was still very slow, and Ma Zhong and Ma Lingling both tightened their attention.

The two of them kept praying in their hearts, hoping that this time Nangong Xuanke would not make a mistake.

A minute passed, and fifty steps ago, although Nangong Xuan walked slowly, it was also extremely smooth.

But after fifty steps, his speed slowed down significantly, and with each step, he needed to think for a while.

Even so, Nangong Xuan still advanced to the position of the ninety-ninth step, and he only needed to take one step forward to calculate the nine-square grid.

Just when Ma Zhong and Ma Lingling thought that Nangong Xuan was about to succeed, she didn't want Nangong Xuan to stop and stand motionless.

Ma Lingling asked puzzledly: "What is the situation, why is this happening suddenly?"

Ma Zhong smiled bitterly: "I don't know."

If Nangong Xuan was twenty steps away, he could more or less see something, but he had reached ninety-nine steps, which was completely beyond the scope of his cognition.

At this moment, Nangong Xuan also knew that he had walked ninety-nine steps, and as long as he took one step, he would be able to get out of the nine-square grid, but at this step, he found that there was no road ahead of him at all.

Is it just like that? According to the calculation, it shouldn't be like this, right, could it be that this nine-square grid itself is a dead end, and there is no so-called exit at all?

No, no.

Nangong Xuan shook his head, he felt that this nine-square grid should not be so simple, and it was even more impossible to be a dead end.

Nangong Xuan stood still and didn't move, but in his mind he began to review the path he had taken.

After some recollection, Nangong Xuan can confirm that the path he took was absolutely not wrong.

With a slight groan, Nangong Xuan calculated the route again, but this time he no longer calculated it from the entrance, but from the exit, and made a reverse calculation.

Just when Ma Zhong and Ma Lingling looked at Nangong Xuan with a worried expression, Nangong Xuan opened his eyes suddenly.
