Fei Ruo was an ordinary demonic beast, and Yuan Fei didn't dare to be interested. But although this wolf's aura is not high, it has such a strange escape technique, which can't help but make him a little curious.

After the thought turned, Yuan Fei's body surface flashed, and he followed with great speed.

After about a quarter of an hour, Yuan Fei still couldn't keep up with the demon wolf, but he just barely followed behind, which made him want to figure out the reason more and more.

In the end, the demon wolf actually disappeared out of thin air after a flash of light on the surface of his body.

Seeing this scene, Yuan Fei was stunned at first, but immediately noticed something, and the light of the Nine Yin Ghost Eyes on his forehead flashed wildly.

"It's ......"

Under the ghost's gaze, although it seems to be empty, there is a huge palace on the opposite side. It's just that the palace is shrouded in a mysterious prohibition, and it can't be seen from the outside.

After Yuan Fei touched his chin, his shoulders shook and he also disappeared without a trace.

And after Yuan Fei reappeared, the seemingly majestic hall suddenly appeared in sight.

Yuan Fei just glanced at the main hall a few times, and then immediately took off into the air, and flew into the main hall in a few flashes.

At a glance, this hall knows that it is a little old, the demonic aura is strong, and it has been gathered for a long time, although it looks very solemn, but it is full of ancient atmosphere. As for the demon wolf from before, he had already gone to the depths of the main hall first.

Yuan Fei groaned for a while, his body shook, and he followed silently.

But just as Yuan Fei came to an underground passage, a roar suddenly came from the end of the passage, and then two powerful auras shot out like lightning towards the place where he was.

Yuan Fei's heart froze, and he hurriedly used the secret technique, and his body turned into invisible in a flash.

"It's strange, how could that demon wolf disappear out of thin air?" A moment later, two black lights flew in, and with a flash of light, two old men appeared from them.

One was tall and dressed in a green robe, the other was dressed in a purple robe with a beard and looked to be in his fifties, and it was the Soul Demon and the Sword Traceless, and the person who spoke was the Soul Demon Demon.

"Sure enough, he was gone. The monsters in this demon island are really evil, although this wolf is only in the middle level of the third level, but the speed of its escape is still above you and me. Sword Traceless' face sank.

"It's just a third-level demon wolf, even if the escape technique is strange, there is no obstacle to you and me. According to the old man's opinion, let's hurry up and look for the treasure, I'll be delayed for a long time. The Soul Demon said disdainfully.

"Hmph, those two demons are really insidious enough, the map I was waiting for was incomplete, fortunately you and I studied it carefully in advance, otherwise I don't know how much it will cost. Sword Traceless scolded angrily.

As soon as the words fell, the two of them were about to turn back. But at this moment, Jian Wuxian seemed to sense something, and suddenly stopped.

"What's going on?" the old demon of the soul demon was also stunned, and asked suspiciously.

"What kind of person is sneakily hiding here? Don't show up quickly, or the old man will not be polite. Jian Wuxian didn't answer, but looked around with a slight squint.

"Brother Dao won't be mistaken, the old man didn't find anything unusual. Upon hearing this, the old demon of the soul was immediately shocked, but after releasing his divine sense to carefully examine it several times, he did not gain the slightest.

"Fellow Daoists, don't forget, the old man has a spirit bead, as long as he is close to the old man within ten zhang, even if the monk is within ten feet, it is difficult for the monk to escape the detection of this bead. Sword Traceless' face sank.

"Hiss......" The old demon nodded suddenly, and his brows furrowed.

After the two of them glanced at each other, they raised their hands almost at the same time, and the demonic qi in the passage immediately surged, turning into demonic recklessness and swooping out in all directions.

At the same time, somewhere in a seemingly empty corner, suddenly a figure flashed, and Yuan Fei emerged from it, and at the same time, with one hand, a black sword qi shot out, smashing all the demons that rushed in his face.

"Daoyou's concealment technique is really mysterious, if it weren't for the old man's treasure, he really wouldn't be able to find your traces. Sword Without a Trace grinned.

"Two Taoist friends, Yuan is just chasing a demon wolf to this point. In order not to misunderstand the two, this is hidden in the figure, but there is no other meaning. Yuan Fei said with a solemn face.

From the conversation between the two just now, Yuan Fei had already roughly guessed the identity of the other party.

As far as he knew, these two people were almost one of the strongest monks of the same rank in the Great Xuan Kingdom, even one of them was very difficult, and Yuan Fei had to be cautious when facing two at this time.

"Even if what you said is true, since you have been met by us, Daoist friends should stay here. After a sneer, the Soul Demon suddenly raised his hand and released nine balls of light.

As soon as these balls of light flew out, they immediately rose against the wind, and in an instant, they turned into nine skulls the size of a millstone.

Then the nine huge skulls let out an eerie laugh of "quack", and each of them spewed out a black flame, which seemed to be extremely ferocious.

Almost at the same time, the sword was a little more in the air, and two flying swords, one black and one purple, were released at once, just a circle, and a layer of two-color sword net was formed when it landed.

Seeing this, Yuan Fei's heart couldn't help but sink. But with a shake of one hand, the Fire Devouring True Demon Sword soared into the sky, transforming into a black sword qi and attacking away.

Not only that, but with a flip of his right hand, a black jade bottle flashed in his hand, and it was the demon refining bottle.

As soon as Yuan Fei held the magic bottle in his hand, he immediately pinched it with one hand, and at the same time, he also recited an obscure spell in his mouth.

The next moment, the surface of the magic bottle flashed, and a black gas erupted from it, condensing, and it was a monster with three demon heads.

As soon as this monster appeared, the three big mouths were under one and one after another, spewing out flames, thick smoke, pillars of light and other attacks, which were mixed with the black sword qi, and forcibly resisted the attacks of the two demons for a while.

Seeing this scene, both Sword Traceless and the Soul Demon were shocked.

It's no wonder that this is one of the most powerful means of the two, and under the combined efforts of the two, the other party is unscathed!

Thinking of this, the two demons couldn't help but have a great increase in their killing intent in their hearts. If such beings let them go, they will inevitably cause great disasters afterwards.

Sword Wuxian let out a low cry, his palms were put together, and as the spell in his mouth became more and more rapid, a pitch-black short blade appeared in his palm, and countless black qi were wrapped around it.

And the old demon of the soul raised his hand and slapped it on the back of his head, and with a "poof", a golden light erupted, which was condensed, and it was a small golden sword.

"Slash!" the old demon shouted, and the golden sword immediately shot out at the opposite side.

At the same time, Sword Traceless shook his hand suddenly, and the pitch-black short blade also shot out first.

Seeing this, Yuan Fei's expression was abrupt, and without saying a word, he flipped over with one hand, and a small black nail appeared in the palm of his hand, and frantically instilled the true yuan into it.

The next moment, Yuan Fei shook one hand, and the small black nail disappeared in a flash, and hundreds of black lights appeared strangely in mid-air.

"Bang bang" a burst of blows, whether it was a pitch-black short blade or a golden small sword, all of them were resisted.

"Lingbao!" Seeing this, Sword Traceless and the Soul Demon first exclaimed, but immediately showed a greedy look, each of them shouted angrily, and tried their best to urge the magic weapon.

As for Yuan Fei, who was trapped in the Demon Flame and Sword Net, his face became gloomy. Although it is said that the true yuan is strong, if it continues like this for a long time, it will be greatly disadvantageous to itself.

Thinking of this, Yuan Fei immediately raised his hand and slapped it on his chest, and the light flashed, and a black light and a blue light shot out from it.

As soon as the two avatars appeared, they pinched the magic trick one after another, threw themselves at Yuan Fei, and disappeared again.

And as soon as the incarnation entered the body, Yuan Fei's body suddenly burst into golden light, and his body actually rose wildly in the wind, turning into a giant of several feet, and then a streamer flashed, and a layer of purple crystal armor appeared out of thin air on his body surface.

After doing this, Yuan Fei's aura soared, almost reaching the peak of the later stage.

That's not all, Yuan Fei grabbed the void with one hand, and the equally huge Fire-devouring True Demon Sword was held in his hand, and then with a sudden shake of one arm, a thick sword qi that was seven or eight zhang long flew out.

With a "bang", the seemingly powerful sword net and demon flame were actually broken open under the power of this blow.

Then after Yuan Fei took back the three demons with one move, he immediately strode out of it.

However, Fang got out of the predicament, but the Sword Traceless and the Soul Demon stopped the exit at some point, and raised their hands together, unleashing a fierce attack again.

Seeing this, Yuan Fei's eyebrows couldn't help frowning. However, he didn't dare to slack off, and with a wave of his hand, he once again stimulated a thick black sword qi, intercepting all the attacks.

Then Yuan Fei glanced at the two demons with a solemn face, he had no intention of continuing to fight, his body surface flashed, and he shot into the depths of the passage, and at the same time, his sleeve robe shook, and a small black nail appeared in his hand.

Yuan Fei was so fast that with only a few flashes, there was no trace.

"Unexpectedly, this person not only has a spiritual treasure, but also has cultivated so many mystical secret arts, it seems that this person's origin must be extraordinary. Jian Wuxian said with a gloomy face.

"No matter what, it must be destroyed here today, or you and I will never have peace in the future. The old demon said with a fierce face.

"This is natural, as long as we can get a treasure of it, we won't take this big risk in vain. After the sword without a trace nodded, he immediately urged the escape light, and then chased after the soul demon.

And Yuan Fei flew all the way, and he didn't mean to stop at all. However, this passage is intricate, and I don't know what danger there is, Yuan Fei didn't dare to really fly with all his strength, I am afraid that it will not be long before the two of them will catch up.

After a while, Yuan Fei, who was flying away, suddenly had his eyes lit up, and his speed suddenly surged.
