In order to get the Heavenly Demon Blue Flame, he was thrilling all the way, and he was quite sad, but fortunately, he finally reached his destination.

His own preparation is sufficient, the three major Douhuang-level combat powers, as well as the elixirs he has refined in the past few days, and the spirit runes he has made, should be enough to deal with most dangers.

Yun Yun asked softly, "Childe, shall we go in now?"

"No, observe and observe. Xiao Feng shook his head, and did not act rashly.

Although he has confidence in himself, how can he ignore the danger factor of the Heavenly Demon Cave, he must test it and know it before entering.

He immediately asked the Sky Storm Bear to find three fourth-order demonic beasts, planted beast marks on them, and asked them to explore the way.

The three-headed fourth-order demonic beasts cautiously entered the mist, and Xiao Feng felt their every move through the beast seal, which was a novel experience.

With the beast seal, his vision can be extended infinitely, and everything that the three-headed demonic beast sees now is clearly presented in his soul sea.

It turned out that behind the fog was a large mountain, and there were many caves on the mountain, which looked like a hornet's nest from a distance.

This is the Heavenly Demon Cave, the caves on the entire mountain are connected, and the inside of this mountain is hollowed out, and there are countless passages inside, like a labyrinth.

After a few demonic beasts entered, they did not encounter any danger, neither the legendary invincible beast venerable, nor the so-called divine fire, and gradually became bolder, and began to gallop, and soon approached the cave.

How could there be no danger? Could it be that the legend of the Heavenly Demon Cave is fake?

"Whew!"

Just when Xiao Feng was puzzled, a demonic beast entered the cave, and before he could send out any information, a miserable scream sounded.

The screams were miserable and short, full of fear, as if something terrible had happened.

What's in there?

Fourth-order demonic beasts are not weak, even if they encounter sixth-order demonic beasts, they won't even have time to reflect.

You must know that as long as it is a Warcraft, it will always take a little time to make a move, and what just happened is obviously not done by Warcraft.

At this moment, the other two demonic beasts had already approached the entrance of the cave, and Xiao Feng concentrated all his attention, hoping to find something.

However, the situation of these two demonic beasts was the same, as soon as they entered the cave, there was no sound, and Xiao Feng's perception was blank.

No, not unnoticed, he vaguely saw an eye.

A huge pupil without the whites of the eye, as black as thick ink, is full of infinite suction, and wants to suck all the human mind into it.

As soon as he glanced at it, Xiao Feng felt chills all over his body, as if he had sunk into a bottomless abyss, and his soul was about to die.

It's horrible!

Xiao Feng's spine shuddered, and his face turned pale.

If he hadn't explored through the beast seal, if he hadn't been too far apart, the result would probably not be much better than the three demonic beasts.

Fortunately, he was cautious, if he thought that he was a disciple of the Immortal Sect and could ignore everything with all kinds of magical means, it would be a big mistake.

"Childe!" Yun Yun saw that Xiao Feng's expression was wrong, and hurriedly reached out to support him.

Xiong Da also walked over and said in a suppressed voice, "Childe, are you okay?"

"It's all right! It's just an amazing discovery. Xiao Feng shook his head and began to sit down cross-legged.

He did have a bold guess in his mind, and he needed to extrapolate and verify it.

Xiong Da and Yun Yun looked at him suspiciously, but when they saw that he was thinking, they silently stayed aside and said no more.

Xiao Feng adjusted his state, his consciousness sank into the Immortal Liberation Order, and he kept inquiring about the information about the Heavenly Demon Cave.

It's just that most of this information is just some basic information, but it is extremely vague and useless about the interior of the Heavenly Demon Cave.

The only valuable information is that there are some legends about the Heavenly Demons.

The Heavenly Demon is the most powerful race in the Ten Thousand Worlds, and it has many similarities with the Terrans, or it can be said that it is a very special branch of the Terrans.

Their innate qualifications are extremely high, and their cultivation is many times faster than that of ordinary human races, which causes every Heavenly Demon to have a strong strength.

However, they also have a lot of people, and with their overall strong strength, they have occupied many top-level worlds, and their members are all over the heavens and ten thousand realms.

According to the records of the Immortal Liberation Order, there is an organization called the "Soul Palace" in the Douqi Continent, which is related to the Heavenly Demon.

Even, from all kinds of information, it is speculated that the cosmic tribulation mentioned by the old Taoist priest is also related to the heavenly demons.

Xiao Feng was terrified in his heart, the Heavenly Demon Clan was so powerful, could the name of the Heavenly Demon Cave be related to the Heavenly Demon?

The race that can dominate the top world, how can it be dealt with by itself now?

It's just that his current cultivation is too low to fully play the function of the Immortal Liberation Order, and the information he queries is extremely limited, and he can't really understand the Heavenly Demons.

So, don't think about these things that are far beyond your vision.

Thinking back to reality, Xiao Feng was in a calm mood, no matter whether this place was related to the Heavenly Demon or not, he couldn't enter Baoshan and go back empty-handed.

Strange fire, I'm going to decide!

After strengthening his confidence, Xiao Feng closed his eyes again and used the Heavenly Machine Technique to speculate.

After a while, a smile appeared on Xiao Feng's face, slowly opened his eyes, and said to Yun Yun and Demon Sky Storm: "It's already afternoon, let's wait for another four hours and enter the mountain in the middle of the night." ”

After that, I fell into retreat again, and took advantage of this time to prepare again.

Although the result of the prediction is that good fortune and misfortune depend on each other, but luck is not immutable, and if you are careless, there is also a possibility of change.

Opportunities have always been given only to those who are prepared, and only when the preparations are done in place can it be possible to turn danger into safety and turn danger into relief.

In the past few days, I have gained a lot along the way, and now I can tidy it up.

It took a whole hour for Xiao Feng to preliminarily complete the classification of materials, and seeing the mountains of materials, Xiao Feng was so happy that he couldn't keep his mouth shut.

All kinds of precious medicinal materials were placed in large piles, all of them were elixirs, and none of them were below the second order.

Most of the skin, bones, and demon cores on the demonic beasts are above the third order, and there are even some bones of the sixth-order demon emperor.

There are also many other special materials, such as the extremely rare Cold Star Iron Mother in the outside world, which is the best refining material.

Xiao Feng finished sorting out the harvest and began to make alchemy talismans.

On the way ahead, I had already taken the time to refine a lot, but now when I saw the situation in the Heavenly Demon Cave, I felt that it was not enough, and I had to prepare another soul purifying pill, a third-order pill.

This elixir can purify the soul without any pollution, and it can also keep the soul clear all the time, and it can also replenish a part of the soul energy, which is the best of the third-order pills, and the effect is not even lower than some fourth-order pills.

After refining the Soul Purifying Pill, Xiao Feng's eyes were on a pile of demon cores, and he had already made enough spirit runes, even if he made some more low-level spirit runes, the effect here would not be great.

The really useful thing is the magic explosion talisman, and this time I have to challenge the fourth-order magic core, or even the fifth-order magic core.

Taking out a fourth-order demon core, Xiao Feng's expression flashed with a touch of solemnity, although the difference between the fourth-order and the third-order was only one order, the energy contained in it was very different.

Therefore, the difficulty factor of production is also increased exponentially.

Xiao Feng took out the carving knife and carefully carved it on the demon core, he was already very skilled in this step, and there was no problem.
