After carefully examining the colored feather for a while, Feng Ruo immediately rummaged through the storage belt for a while, he now had to find something to pack the golden feather, and then stay away from here, find an absolutely hidden place, and then conduct research.

Soon, Feng Ruo's eyes saw ten more objects of different sizes and shining essences, but this was the essence of the dark iron he had collected in the past many years, this thing was originally thinking of refining the Natal Flying Sword, but later he had better materials, so it was abandoned to the side, until this moment, it was of some use.

Time is pressing, Feng Ruo can't take out the refining tripod, and the medium-grade refining tripod he is in is still the defective product he bought a hundred years ago, it is estimated that if he puts the purple fire in it, it will be burned to ashes in a few moments.

Putting the golden feather aside, Feng Ruo's flame grabbed the ten pieces of essence and iron so directly, this scene was normal—but in the next moment, a purple flame rose up, and the stone chamber he had dug was filled with waves of heat, and in just a few breaths, all the surface rock walls around this stone chamber were melted and transformed into hot magma

This is the true power that Purple Fire has after advancing, even Feng Ruo himself felt that it was incredible, but he didn't pay attention to this, the rock wall was just a very ordinary kind of rock, naturally it couldn't withstand the high temperature emitted by Purple Fire, and the ten pieces of Essence Xuan Iron of different sizes were much harder, but they had also become extremely red

If this scene were seen by other cultivators, they would definitely be shocked, because even if the spirit infant stage was high, they would not be able to do this

Feng Ruo didn't care about all this, and continued to release the sensibility of the purple fire, constantly burning the essence of the dark iron in the middle, and after about ten breaths, the originally hard essence of the dark iron gradually softened, and finally turned into a flowing liquid tooth

This crimson liquid was wrapped in purple fire and then began to change according to Feng Ruo's thoughts, which he was still very satisfied with, because as long as there was an image in his mind, what image could purple fire transform into, it was not an exaggeration to describe it as lifelike

Soon, the liquid melted by the essence of the dark iron was elongated into a mold that was about the size of the golden feather, and then, under the control of Feng Ruo's thoughts, it turned into something like a scabbard.

At this time, Feng Ruocai quickly took out a full thirty-two high-grade metallic five-element stones, thirty-two high-grade fire attribute five-element stones, and thirty-two high-grade earth-attribute five-element stones, which he quickly set on the mold that was still in a liquid state.

Of course, there is no doubt that each of these three attributes of the top-grade Five Elements Stone represents a formation, the metallic Five Elements Stone is sealed and used to reinforce, while the Fire Attribute Five Elements Stone is used to enhance fire resistance, and the Earth Attribute Five Elements Stone is used to cover the breath.

As soon as these three formations were completed, the purple fire that originally supported this strange scabbard immediately began to weaken, and finally disappeared without a trace, and the strange scabbard also began to condense, and when this thing was completely cooled, Feng Ruo's right side also returned to normal, at this time, the whole process only passed the time of two hot teas, and such a fast speed was absolutely terrifying.

Feng Ruo was very satisfied, not only satisfied that his purple fire had become stronger, but also that this strange scabbard was very much in line with his wishes, although it was still rough and unsatisfactory, but the key problem was to be able to hold the golden feather safely, which was what he wanted.

Without much hesitation, Feng Ruo directly put the golden feather into the special scabbard, and in an instant, the originally normal scabbard immediately turned red, and he could see wisps of fine smoke rising up.

"Tut, this feather is really amazing, it is estimated that this scabbard can only last for ten hours, hey, I am really looking forward to it, Feng Ruofeng Ruo is very careful, he doesn't know how far the hunting range of the fourth-level demon king is, now he, although he has the advanced purple fire, and the shadowless bead to cover the traces, but the facts have proved that the shadowless bead is not effective for all demon kings, otherwise he would not have been caught by the fourth-level demon king last time.

Just kept moving forward, Feng Ruo estimated that he had rushed out at least thousands of miles, but the undulating mountains still had no end, on the way, he didn't see a demon king, let alone a living thing, all the places were barren, but this is not difficult to understand, after all, it was a fourth-level demon king! There will always be its own sphere of influence, and the range within a radius of more than a thousand miles is already small. ..., in the process of moving forward, Feng Ruo also found a very interesting phenomenon, that is, no matter any terrain, mountains, basins, canyons, plains, all the ground has a very smooth cover in front of it, as if some terrifying force has smoothed them out! For this strange phenomenon, Feng Ruo remembered the massive magma and fire sea in the fourth-level demon king's cave, and now he knew that the body of the fourth-level demon king was in the huge magma and fire, so this smooth ground with a radius of thousands of miles could also be explained.

There is no doubt that the ground was scorched into magma by the scorching heat, and when it cooled, it formed this smooth cover.

It's just that it's hard for Feng Ruo to imagine what kind of grandeur and despair it must be when the fourth-level demon king is rampaging in this black abyss with the overwhelming sea of magma and fire!

It's unthinkable!

When Feng Ruo walked forward again for about a thousand miles, he finally met a second-level demon king with obvious strength, but with the shadowless bead, he didn't attract the attention of the second-level demon king at all, and now he already knows that as long as it is a first-level and second-level demon king, he basically can't see through the invisibility of the shadowless bead, and the third-level demon king He hasn't tried to know, but the fourth-level demon king must be able to see through it.

Next, Feng Ruo encountered the three-headed second-level demon king, I have to say that once he left the territory of the fourth-level demon king, the number of these guys immediately increased, and he also found that there was no shadow of the first-level demon king here, even the four second-level demon kings he saw just now, their strength was at the peak of the second-level state, and it seemed that they were only one step away from the third-level demon king.

This situation made Feng Ruo a little thoughtful, and at the same time, a bizarre thought also appeared in his heart, that is, could it be that a large number of demon kings in this black abyss were also looking for those dragon crystals like the Jiaolong clan, and then continued to advance?

Because according to Feng Ruo's observation, the aura in this black abyss is not abundant, but the number of demon kings here is too much, and they don't want to cultivate normally between them at all, so there must be a way for them to advance quickly, and apart from Long Jing, he really can't think of anything else with this ability!

The more he speculated like this, the more shocked Feng Ruo's heart became, because no matter whether these demon kings were really chasing that dragon crystal or something else, one thing was clear, that is, this black abyss was a real killing field, including those Jiaolong clans, although they had wisdom that was not inferior to humans, but it was also unavoidable, if they wanted to survive, they had to go all out to enhance their strength!

After silently bypassing a second-level demon king, Feng Ruo could no longer see the mountains in front of him, and a huge crack directly blocked his way!

This huge crack was really indescribable, because he couldn't even see the cliff opposite, and countless gray clouds of smoke floated above the crack, and even his mind could not penetrate it.

And if you go down, it is still endless, looking hard, you can only see the deep darkness and dead silence, obviously there is no wind howling, but it makes Feng Ruo feel cold all over his body, and even he has the illusion that he can't fly over this huge crack.

This crack has no head and tail, and if you can't see how long it is, maybe it's a thousand miles, maybe it's ten thousand miles, and even, this terrifying crack is the boundary that divides the two worlds!

It's so weird, Feng Ruo can see that the cliff under his feet is as smooth as a knife, and there is no moss or dust on it, as if it is still in the state of the moment it was split!

Feng Ruo hesitated for a long time, even though he now had purple fire wings, he still didn't dare to leap over this crack that was not known how wide, because vaguely, he felt that there was an even more unimaginable danger on the other side of this crack.

"Let's stay on the side of the rift, at least this is still a buffer area, as long as you avoid those third- and fourth-level demon kings, you can still mix in!" Feng Ruo thought to himself, now he is more and more unable to figure out what kind of world this black abyss is! He smiled to himself, but he unhurriedly took out more than ten pieces of thousand-year-old Xuan Ice again, and surrounded the entire scabbard in a rapid change, and suddenly, he could no longer feel a little heat outside.

After doing all this, Feng Ruo immediately put the special scabbard that was wrapped in layers into the storage belt, and then rushed out without looking back.

This time, Feng Ruo didn't urge the Allure Sword to hurry away, nor did he use the purple fire wings, but used his strength to press his feet, and rushed into the darkness in the distance just like that.

The reason why this is so is because Feng Ruo doesn't know the direction at all, and he doesn't know where to be safe, and his only reference position now is the lair of the fourth-level demon king, so his choice is to stay away from the lair of the fourth-level demon king as much as possible, because next, he not only needs to be safe, but also needs an absolutely secret place, and then impact the spirit infancy.

This is the only guarantee that he can leave this black abyss alive, and only strong strength can not become the mouth of the demon king. ）
