A group of people used the ladder pierced by Xu Xian to arrive at the entrance of the cave.

It was dark inside the cave, and I couldn't see my fingers.

"Puff puff puff puff..."

A group of bats flew out quickly with flapping wings.

"Are you sure this is here?"

Xu Xian looked at his senior brother and asked.

"It's almost ten!" Senior brother looked at the map again, but he couldn't guarantee it.

Without going in, who knows if it is here. Although there is a map, it is very likely that the map is fake.

The most important thing is that after so many years, the mountains, rivers and landforms will change.

"Pindao, go ahead, you guys follow." Xu Xian looked at everyone with a serious face.

Then he took steps and walked towards the cave.

The cave is very dry.

With the Maoshan Yin and Yang Eyes activated, he can still see things even in a dark cave.

There are many skeletons in the cave, of unknown animals, lying on the ground.

If you accidentally step on it, the skeleton will instantly turn into a pile of dust.

At a glance, it is obvious that these skeletons have existed for a long time and have turned into powder.

In this way, there might be magic in Daozang that he doesn't know.

The possibility is high.

The mages of the past possessed many long-lost and profound spells.

With one or two spells, this trip is not in vain.

The cave is very long.

Walked for more than ten minutes.

Xu Xian felt that he had arrived inside the mountain, but had not yet reached the end of the cave and did not know where it led.

As he walked, Xu Xian realized something was wrong.

"Wait a moment."

Xu Xian quickly called everyone to stop.

"Senior, what's wrong?" Senior Brother asked.

"has a problem!"

"What's the problem?" The senior brother looked puzzled. He looked around carefully and saw that there was no problem.

The surroundings are quiet and normal, and there is no sense of any danger or problem.

"You guys stand back a little." Xu Xian looked at the crowd and said.

After everyone retreated, he took out three talismans and folded them into paper figures.

Casting spells.

The paper man uses the formation breaking technique.

"Imperial order!" Xu Xian shouted in a low voice.

The paper man came to life with a flash of golden light, and then walked behind him.

Haven't taken five steps yet.

"bump……"

The paper man suddenly exploded and fell apart.

"Sure enough, we entered the phantom formation!"

Xu Xian's face was serious.

If it were not in the formation, the paper man would not walk at all, but would stand still.

As for the explosion, the formation has the means to break the paper man's formation.

It allows him to enter the formation without being aware of it, and he also has the means to break the formation with the paper man. The person who set up the formation is quite accomplished in the formation.

"We have entered the phantom formation? No way!"

The senior brother looked astonished.

Entering the illusion formation, how could they not notice it?

But I really haven't noticed it now. Could it be that the seniors made a mistake?

Looking at the senior's appearance, his face was solemn, and it didn't look like he had made a mistake.

"The people who set up the formation are very clever. Fortunately, you invited Pindao, otherwise you would be trapped at the entrance of the cave and unable to get out.

Most of the corpses that appeared just now were trapped in the phantom formation and could not get out, and were consumed alive by the phantom formation."

"Senior, do you have a way to break the formation?"

"Um."

Xu Xian nodded lightly, then looked around carefully.

Now that we know there is a formation, we must be able to detect some clues.

A layman may not notice it, but an insider can definitely do it.

Unless the person setting up the formation is much better than Xu Xian in terms of formation skills, then Xu Xian will not notice the clues.

Obviously.

The person setting up the formation did not.

Xu Xian discovered that the stone wall above his head was embedded with a demon pill.

It seems to be the demon elixir of a thousand-year-old demon.

The demon pill contains huge energy and can be used as a driving force to keep the formation running.

If there is one, there must be two more.

Xu Xian searched carefully.

Two minutes later.

as expected.

He found eight.

The eight demon pills are arranged according to the directions of the Eight Diagrams, slowly delivering energy to the formation.

Because they were trapped in the formation, they could not feel the demonic aura and energy of the demonic elixir.

The reason why we can see it is because these eight demon pills are the base of the formation.

Similar to Xu Xian's talisman flag.

A complete formation, like the talisman paper, consists of three parts.

They are the formation position, formation base, and formation eye.

The formation position is the direction in which the formation is arranged.

The formation base is the thing that provides energy for the formation and is placed in the formation position.

As for the formation eye, it is the core of the formation. Energy will enter the formation eye, and the formation eye will transmit energy to the formation.

The person setting up the formation also controls the formation by controlling the formation eyes.

To break the formation, in addition to breaking it with force, the only thing left is to destroy the formation's eyes.

Because without the formation eye, energy cannot be transmitted through, and the formation will be broken without energy supply.

Based on the position of the eight demon pills, Xu Xian can determine that this formation is the Eight Diagrams Magic Heaven Formation.

As a formation master, you naturally need to know many formations.

You don't even know the formations, but you still break them like this? How can you be called a master of formations?

The position they are in now is in the 'away' position.

Breaking the Eight Trigrams Fantasy Formation is easy to say, but very difficult to say.

Find eight directions and attack them together. The formation can be broken.

And these eight directions are naturally where the demon pill is located.

Attacking one direction alone will not only fail to break the formation, but will also activate the hidden killing formation of the Bagua Fantasy Array.

This formation is not only a fantasy formation, but also a killing formation, a dual formation composed of two formations, commonly known as an formation within an formation.
