The huge colored rays containing lightning and the energy of the five elements can be blocked by huge mountain peaks, and they can also be crushed on the spot in an instant.

Although the huge blood sword rays of the secret technique sacrificed by the old man who had cultivated in the Boundary Breaking Realm were also extremely powerful, they still failed to block it even a little under the attack of the huge colored rays formed by the fusion of several energies.

The huge colored silk threads wrapped in dazzling colored mangs formed a strand, in which the Dao Dao Formation Spell Ring appeared sharp and compelling.

A loud whistling sound thundered like a shocking sound wave, threatening to rob a monk's mind and plunge him into a state of confusion.

In the face of such a wave of dense energy attacks in front of him, the old man's complexion finally changed drastically.

Seeing that this combination formation was not at all what he had expected before, under the combination and fusion of several kinds of energy, the attack energy effect was so powerful that the old man's heart was also cold.

Seeing that the secret technique he sent could not stop this attack, without hesitation, the origin energy in his body surged, and a powerful secret technique at the bottom of the box was sacrificed.

"Good, good. I never thought that you, a junior, would have such a means. It's really surprising to the old man, but if you let the old man sacrifice this secret technique, then you will live to the end.

The old man originally wanted to capture you alive and let you worship under the old man's door, but now he can't, this secret technique appears, and you will see the essence blood of the cultivator, junior, you will die. ”

With the blood shadow of the old man's huge head, and a furious and laughing word, I saw that the face composed of blood-red mist several feet large suddenly appeared extremely fierce, and after a terrible howl.

It turned out to be a rapid flicker, turning into three old men's faces that were nearly two feet in size, and the blood-colored mist was transformed into red glow energy.

Yun Yu stood hundreds of zhang away, looking at the scene that suddenly appeared in the formation, and his complexion changed suddenly.

Underneath the three huge heads that the old man had transformed, a thick blood-colored mist had been shrouded, as if the energy needed by the old man's skull was all powered by the blood mist below.

The rapidly expanding blood mist layer spread towards the surroundings at an extremely fast speed, and where it passed, the formation energy retreated sharply, as if it was not at all above a level from it, and it was impossible to compete with it.

A monk who was facing the enemy in the formation actually showed such an abnormal change, and when Yun Yu saw it at first glance, his heart couldn't help beating wildly, and his breathing was slightly short.

The huge bloody face, the mouth, nose and expression on it, looked strange and terrifying, and under the three huge heads, a blood mist was filled, as if it was the body of the old man.

Such an abnormal change is enough to prove that this old man's secret technique is no different from that of a demon. It can also be said that this old man can actually perform the secret techniques of the demon world.

A strange and bloody aura came from the blood mist, like a majestic blood-colored cloud rolling and obscuring, and the yin energy in the surrounding sky condensed in, making the blood mist diffuse and tumbling faster.

The first wave of dazzling colors was swallowed by the huge head, and it suddenly disappeared without a trace.

Although under Yun Yu's mental contact, he could still sense his state and was not imprisoned by the other party's energy, but at the bottom of the majestic blood mist, he couldn't break free.

Seeing that the other party was actually using such a strange secret technique, Yun Yu couldn't help but raise his vigilance to the extreme.

Hearing the other party's bold words, Yun Yu, who had a solemn face, did not show the slightest fear. The soul power in the body gushed out, and the magic trick in his hand was pointed in the void.

Suddenly, I saw a huge colorful light flash out from a hundred zhang in front of him, and suddenly turned into a colorful sword light that formed a giant sword, and under the rapid radiation in the air, one after another sword rays flashed.

In an instant, a huge colorful light sword condensed and formed, and its sword body flashed with colorful light, in which the aura of various energies was diffuse, and the lightning and array patterns of the Dao Dao were shot and swam in the colorful light, showing unfathomable power.

Just when the old man used his secret technique and turned the huge head into three, the huge sword body had already been generated, and in a flash, it slashed directly towards one of the heads.

The sword body escaped at high speed, and the surrounding heaven and earth yin energy absorbed by the old man's illusory blood mist was instantly melted by a powerful lightning energy when it touched the colorful light wrapped on the sword body.

Behind the rapidly advancing sword body, there was a long tail, which was the dazzling silk thread energy composed of the energy of the formation.

The three big heads stood proudly on the spot, facing the huge sword body that rushed towards them, and they did not have the slightest fear of dodging.

There was a terrible howl, and the three heads opened their mouths again, scrambling to bite the sword.

The large head composed of these three blood rays has the ability to directly swallow the huge sword rays and the energy emitted by them.

The powerful attacks of the two sides touched together again in an instant.

What made Yun Yu not disappointed was that the powerful power of the Great Five Elements Soul Sealing Array that had been carefully refined by him was even surprising in his heart.

At the moment when the huge sword body collided with the huge mouth of the three heads, there was no loud sound, but a burst of chill that made people feel a chill all over their bodies.

In this almost muffled and inaudible sound, there was the sound of lightning flashing, the sound of sharp light breaking through the viscous blood mist, and the sound of energy flashing.

Under the collision and handover of many energies, the giant mouths of the three heads were suddenly crushed on the spot, and the surrounding areas of the three giant mouths on the spot were chaotic.

The huge blade of the sword quickly escaped the flying scroll, slashing down at the head designated by the mind, and swept and twisted.

At this time, the dazzling color that followed seemed to suddenly increase the energy delivery, and the entire "tail" suddenly enlarged.

Under the infusion of Yun Yu's soul power in the formation, the attack condensed by the formation, although the power of the rules of heaven and earth contained in the blood mist was stronger than the formation in sense. However, under the fusion of the five elements of energy with the energy of the Yin attribute and the energy of the fire.

This colorful energy has a strong restraining effect on the Yin Qi attribute, and the huge sword body formed a huge attack, or broke through the old man's defense.

Although the seemingly huge sword body easily broke through the huge mouth of the skull, the colorful energy that had been devoured before appeared from the blood mist.

But at this time, Yun Yu also knew in his heart that just by relying on this formation, he would definitely not be able to completely solve the blood mist that had already spread to the entire valley at this time.

When one of the three major heads was cut off, the sword body of the huge sword light had already dimmed, and the energy dissipated again, returning to the middle air of the formation.

"Hmph, it's too late for juniors to want to escape at this time. ”

Just when Yun Yu's mind retreated, he let the formation play the last and strongest blow, and let it explode and damage the enemy's foundation.

A shout suddenly sounded from the viscous blood mist, and then a huge blood mist cloud suddenly rolled and surged, as if some kind of behemoth was activating in it, hoping to condense a new skull illusion.

As the huge blood mist cloud rolled violently, the blood mist that had been diffused in all directions suddenly rolled up into the air at this time.

At this moment alone, the entire air of the array was completely shrouded in a huge blood mist.

Yun Yu, who was standing in the air, was swept by the rolling blood mist in the array, and he had no accidents, and he was also shrouded in a huge blood mist.

Feeling the bloody stench in the blood mist, although Yun Yu had several defenses and body, he couldn't help but hold his breath as soon as possible to cover his senses all over his body.

There was also a sudden strangeness in his heart, this bloody aura seemed to be somewhat familiar, this seemed to have some of the same aura as the bloody fog that occurred in the Demon Soul Valley in the Lost Land, could it also be related to the origin of the Demon Soul Secret Domain.

The viscous fishy mist had an extremely powerful energy aura, although it was not strong enough to threaten Yun Yu's own stability at this time.

But if it was an ordinary powerful cultivator who entered it, it was difficult to say whether he could rely on the shield formed by the energy in his body to resist it.

Just when Yun Yu's soul power detected the array, and the blue light in his eyes flashed in the surrounding places, wanting to break away from this formation and explode this formation, suddenly danger suddenly came.

"Huh!" A bloody phantom with almost no energy suddenly flashed behind Yun Yu's figure, and a hand that flashed a compelling red light suddenly grabbed towards Yun Yu's heart.

This strange and almost transparent blood shadow appeared strangely and quickly, and before it appeared, Yun Yu didn't feel it at all.

In the face of such a surprise attack from the other party, if you want to dodge, you can't do it.

This strange and suddenly appeared figure, and his whole body was melted into the blood mist that rolled and permeated the entire formation, almost merging with the blood mist.

Suddenly appeared behind Yun Yu, as if it appeared out of thin air, and no trace was revealed.

Yun Yu hung in the blood mist, and he didn't seem to sense that danger was approaching behind him.

Seeing the young monk who didn't react at all, there was also a hint of joy on the blood shadow face.

"Poof!" A dull sound sounded, and a yellow-white spear suddenly appeared at the position of the blood shadow on the chest of the claw.

As soon as the flash of light flashed, it was inserted from the front of the blood shadow, and the yellow and white spear head flashed out from behind the blood shadow, and in just an instant, it was pulled back by the standing Yun Yu, and then disappeared in a flash.

The smile on the blood shadow's face also suddenly condensed, and there was a trace of astonishment, and he looked down at the hollow in his heart, and his face showed a look of confusion and unwillingness.

But in an instant, his expression suddenly froze, and the fierce color reappeared, and at this time, on his side, a fluctuation flashed and a blood shadow flashed on the spot.

At this time, Yun Yu, who had been attacked by an empty cloud spear entity, had already moved his body quickly and retreated several feet away from the ground.

"Hey, the junior is really alert, in the realm of the old man's blood mist, you can still avoid the old man's attack so quickly, and you can fight back, even the old man has to admire you a lot. ”
