The place is surrounded by water on both sides, and there seems to be a natural valley behind the mountain.

Because of the relationship between the mountain and the water, and the lair of demon beasts, it is naturally impossible for ordinary people to explore what is in the valley behind them.

But Nie Yunwen is different, although she came here for the fairy grass, she was not too eager for herself.

Moreover, no matter how many things were in Nie Ye's original cave mansion, it was impossible for a demon beast of this level to have many good things.

For Nie Yunwen, a "rich and noble man" who had earned a lot of storage and jade slips in the Qianyuan Secret Realm, the treasures in the cave had almost no appeal, and the role was just to see if there were any clues and clues.

She followed Nie Ye to the cave and only swept around, and found that there was nothing good that she could like.

Although the objects inside all carry some spiritual power, they can still be exchanged for a good price in front of ordinary small families or small sects and scattered cultivators.

Nie Yunwen instructed Nie Ye to pick a few things and put them away, and the rest were tied up with ropes and put away, and handed them over to Zhou Yun and Zhou Qiang to dispose of when they came back.

A pillar of incense was done in less time, and when she reached the mouth of the cave, she glanced at the peak.

It shouldn't be too high for mortals, and it's not too shaky.

The water on both sides is also calm.

The only thing that makes people dare not move to explore is the leader of the demon beasts in the original cave, and the danger that may suddenly appear in the water.

Let's not mention the matter in the water, the leader of the demon beasts in this cave is now her little brother, and the mountain peak is not enough for Nie Yun's cultivation.

So she looked at it for a while and then flew straight up.

As soon as she arrived at the top of the mountain, Nie Yunwen knew that she had come to the right place.

There is a circle on this earth.

She stopped and didn't rush in.

But anyone who knows how to form a formation understands that if he is a master in arranging a formation, he will definitely leave a backhand.

Defend for the bottom, attack for the middle, and police for the top.

Setting up a killing array, although you can have the opportunity to kill the incoming people, you can't guard against the advanced people. If you defend the formation, there will always be a day when the formation will be broken.

Only the vigilant formation is the most powerful, but anyone who breaks in can be detected by the person who sets up the formation, and he will always be caught in the future.

Nie Yunwen is a leader, so she is extra careful.

After a closer investigation, she breathed a sigh of relief, this formation was not a warning formation, but a killing formation.

However, she didn't bother to break the formation, she only used her spiritual power to attach to the lines, and used her usual means to directly open a secret passage and walked in.

"Nie Ye, every step here has my reason, if you come in, it will be in the way, so wait for me outside."

After instructing Nie Ye, she headed into the depths.

The most ingenious thing about this formation is that traps and obstacles are not exposed on the periphery, and they only appear after entering a certain level.

In this case, people who do not understand the formation will wonder if there is nothing here after a calm passage and turn away.

She carefully avoided them all before she saw a tree.

If you look closely at the tree, you will notice that the outline will be blurred at some point.

If you say this to a master of formation, you will immediately realize that it is a typical exit!

Nie Yunwen smiled and stretched out her hand lightly, and the pattern with spiritual power was printed on the bark of the tree.

In an instant, the lines of the trees rippled like ripples, and then they turned into an oval-shaped opening, and the real sky light shone in outside!
