The Demon Clan's retreat holy place is also known as a forbidden place...... Since it is a forbidden place, how can it not be heavily defended? It's impossible to rely on those demon guards outside alone, and there is a layer of defensive formations, right?

Among the peaks of the retreat sanctuary is a huge cavern, like a palace, with a total of thirteen floors, each layer is filled with a thick red mist, and it is impossible to see what it looks like, but from the occasional corner of the blur, you should know that it is not as gorgeous as you imagined. Huo Ranwen ???.? ｒ?ａ?ｎ?? ｅ?ｎ?`ｏｒｇ

The energy filled in the red mist is extremely mysterious, and it has the same effect as Cheng Feng's fog of war, if outsiders enter it and do not understand the mystery of the fog, they will inevitably be blocked and perceived, and their vision will be greatly hindered.

And in addition to this red mist, there are many array mines scattered all over the place in this holy land, and one after another energy aura emanates from it, and there are obviously various formations protecting the holy land inside.

"Whew!"

It was like the sound of a gentle breeze, and then a head poked out of the soil layer of the holy land, and the soil layer was not damaged in the slightest way, as if a head had grown on the ground out of thin air, which was extremely strange.

"What the hell?"

The little ghost carefully glanced around, and then his whole body came out of the soil, and then he saw that with a flick of his hideous claws, several invisible reconnaissance guards had been planted and fell directly into the red mist.

Then, little by little, the little ghost groped its way through the red mist, leaving behind a few reconnaissance guards every ten meters.

On the other side, all the other little ghosts also emerged from under the ground, some of them soared directly into the air and continued to fly upwards, while a few stayed behind to explore the first floor together.

There is more than one floor of the retreat! This is not a secret among the demon clan, after all, many people knew about it when it was built in the first place...... It was only after the construction was completed that it was listed as a forbidden land, and Cheng Feng had already known about these news from Xue Feiqing and Long Yu.

The figure of the little ghost was silent, and it didn't make a sound when it moved, just floating forward in mid-air, but for some reason, suddenly the space around one of the little ghosts trembled, and then a strange force pressed towards him.

Triggered the formation?

The little ghost was slightly stunned, feeling the oppressive power coming from all directions, and already understood that he should have triggered the spatial formation, and the spatial oppression around him was extremely powerful, with the strength of his third-order heavenly demon, I am afraid that he would be suppressed in an instant.

But even so, the little ghost didn't show much nervousness.

Because just when he was about to be annihilated by spatial oppression, a strange spatial power flashed from his body, and then his figure had disappeared.

Portable Hero Mode, Reverse Summon!

"Boom!"

The spatial oppression that came from all directions lost its purpose and made a loud noise in mid-air.

"Not good!"

"Be careful!"

As soon as the other little ghosts heard this sound, they all became nervous, for fear of waking up the demon royal family who were in retreat.

Previously, only the Demon Emperor was led out of the retreat holy land, and no one else appeared, obviously those retreat demon royals were still in this retreat holy land.

If you disturb them, I am afraid that things will be in trouble.

But what these little ghosts never expected was that after the sound disappeared, there was an eerie silence in the holy place covered in red mist.

Quiet, very quiet? Didn't the retreating royalty hear it?

And what is strange is that these little ghosts have been entering the holy land for a while, and no matter how silently they move, there will be a faint aura emitting from them, is no one aware of their existence?

"Put more scout guards first, and put more on each floor!"

"Then stick to the edge of the cave wall on each floor and start exploring!"

"Be careful, pay attention to the formations everywhere, don't spoil the adult's business!"

One of the strongest little ghosts whispered, and then the little ghosts moved again.

"Wait!"

At this moment, a small ghost suddenly stopped and stared at its claws strangely.

This little ghost devoured the demon core before and awakened a special talent, the Purification Talent!

You don't have to think about it to know that this so-called purification talent comes from the purification skill of the League of Legends summoner.

"I just tried to perform the Purification Technique, and I want to see if the Purification Technique can dispel this red mist......!"

As the little ghost spoke, he saw a white halo on his claws, and in the area covered by the halo, the red mist began to become lighter, as if it had been dispelled a lot.

It's a pity that there is too much red mist in the holy land, and coupled with the lack of strength of this little ghost, it is impossible to achieve large-scale purification at all, and even in this red mist, it is impossible to maintain the purification talent for a long time.

"But...... It's enough to know that adults see this! ”

The little ghost looked excited, and turned to look at an invisible scout guard on the ground beside him.

And his every move was also transmitted to Cheng Feng's mind through the reconnaissance guards.

……

……

"Purification can dispel red mist? Not bad, not bad! ”

"In this way, I am more confident that I can explore the retreat holy place clearly!"

The corners of Cheng Feng's mouth curled slightly, and the figure that was moving rapidly suddenly stopped, and slowly turned to look at the Demon Emperor who was chasing quickly in the void in the distance.

As required by the calling, he had to successfully explore the retreat sanctuary and stay in it for more than ten minutes.

Successful exploration means that you have to figure out what is going on on on each level of the retreat, and all the secrets.

There are 13 levels of retreat, so how easy is it to explore each of them?

Not to mention ten minutes, I'm afraid that half an hour and an hour may not be able to figure it out.

Because of this, Cheng Feng cautiously allowed some little ghosts to enter the retreat holy land in advance.

And those little ghosts aren't as simple as pathfinding......!

At this time, in the retreat holy land, some little ghosts were carrying storage ornaments, and they carefully took out pieces of heaven-level array ore from the storage ornaments, and then began to arrange them along the place where they walked, and each piece of array ore was arranged according to a specific trajectory.

"Are the royal families still in retreat still not moving?" Cheng Feng's eyes flickered, and he couldn't figure out the situation for a while.

At this time, the figure of the Demon Emperor had also stopped.

"Aren't you running?" The Demon Emperor's posture was hideous, the thunder flashed around him, and his tone carried anger.

"Run? I'm not just running, I'm just going to take you to find a place to fight! Over here...... Just right! Cheng Feng sneered. (To be continued.) )
