Yun Yu's expression was solemn, he looked at the huge skeleton in front of him, and with a wave of his hand, a red sword light shot out, slashing towards the ancient dragon beast skeleton in front of him.

"Woo......!" With a soft sound, the red sword light energy disappeared in a flash as if it had been slashed into a viscous liquid.

The huge skeleton in front of him did not show the slightest reaction, as if Yun Yu's sword energy attack that could open mountains and split stones could not even itch it.

"Sure enough, the power is unfathomable!" Seeing this situation revealed, Yun Yu's mouth murmured a little joy.

The more powerful the ancient dragon beast bone was, the more it could inspire Yun Yu to get the determination.

Within a month of that, Yun Yu had already entered a state of demonic dazification, and began to use every means he could think of to ingest the skeleton.

What made Yun Yu extremely speechless was that any means he could offer, whether it was an attack method or various spell runes, as long as it touched the strange aura in time, it would disappear in an instant like a mud cow entering the sea.

Even if he sacrificed the broken small bowl and the secret technique of the illusion true body, it was difficult to shake the power of the barrier formed by the strange aura.

What made Yun Yu feel even more strange was that the strange aura energy that could not be seen by the naked eye seemed to be unrejectable to any energy, as long as it was an energy object that invaded it, it would be absorbed by its strong force.

The tenacity in Yun Yu's heart was gradually exhausted after all the secret techniques were sacrificed, but they all ended in failure.

Although the bones of the ancient dragon beast did not have any attack power to display, it was the strange aura that wrapped the bones, which was enough to make him sigh and sigh, and there was nothing to think about.

Within a month, Yun Yu had finally fully detected the size of the skeleton.

This ancient dragon beast skeleton is not a complete dragon beast corpse skeleton, the skeleton part should only be a section in the middle of a huge body nearly a thousand zhang long, and the total length is only two or three hundred zhang.

The bones of this ancient dragon beast did not have any dragon head bones, nor did they have a tail.

The reason why such a part of the ancient dragon beasts existed in a small pool on a remote island in the spirit world made Yun Yu very difficult to understand.

Yun Yu, who tried a hundred methods to no avail, sat cross-legged beside the skeleton, his eyes closed, and fell into retreat, and time passed slowly in his retreat.

In the blink of an eye, nearly a year has passed. The Tranquil Refining God Pool, since the three monks left, no monk has entered it again.

The trial of the secret realm of the Refining Treasure Cave had been closed, and the demon clan man stationed next to the Refining God Pool was really puzzled by the first young monk to enter the Refining God Pool.

Of course, he was familiar with the gray-white pool of water here, which was only a few hundred zhang square. Because he had personally entered the Refining Divine Pool in the last session and refined his divine soul, he was even more impressed by the powerful concussive soul power in the pool of water.

According to the records of the Heavenly Jade Palace, the Great Han knew that there was an unspeakable danger in the depths of the Refining God Pool, and as long as he entered it, whether it was a spiritual realm monk or a Xuanling Realm monk, he would never be able to escape again.

Dahan knew this in his heart, and he was sure that any monk who came to challenge the Treasure Refining Cave Secret Realm trial would know about it.

However, it only took a few days to break through the level of the secret realm of the Treasure Refining Cave, and the young man did not leave the pond before entering the pool, this situation made it really difficult for the big man to understand.

Cultivation is a cultivation that has reached the peak level of the spiritual realm, and no one who has not experienced the flow of blood and rain will plan and act in the face of anything, and there is no reckless action.

Although Dahan had the heart to go down to the pool to investigate, he didn't have the treasure refining order with him on the one hand, so he couldn't stimulate the power of the ban on the refinement of the god pool.

Nearly a year had passed, and Dahan could already be sure that the young monk would not have the opportunity to leave the Refining Divine Pond again.

Because there have been records in the classics since the beginning of the existence of the Refining God Pool, there has never been a record of any monk being able to stay in the pool for as long as a year.

Although the huge strange concussive soul power could refine the monk's soul, the powerful negative effects contained in it were not something that the monk could easily dissolve.

Therefore, no matter how powerful the Divine Soul Realm is, no matter how much Yuan Spiritual Power is stored in the body, it will not be able to resist the turbulent invasion of the strange soul power that continues to gradually increase.

Not to mention a cultivator at the level of the Spirit Realm, even if it is a demon beast or demon cultivator with a strong physique in the Xuan Spirit Realm, he can't think of holding on for more than a month, let alone such a long time.

According to the usual practice, the Refining God Pool will also turn into a pool of clear water in a few months, and if you want to condense the thick state of the gray and white strange aura again, you will only have to wait until more than four hundred years have passed before it can be slowly generated.

Looking at the pond again, the big man's figure flashed, and he flew away towards the area covered by the black rocks.

Every time the Divine Pond cleanses the monk's soul, it is only a year and a half, and he has only been stationed here for more than a year, and the time limit has already arrived.

As the big man's figure shot away, a burst of fluorescence suddenly flashed at the edge of the pitch-black rock area, and it was obvious that the edge of this vast black rock land was equipped with a powerful covering and defensive formation.

What this demon cultivator didn't expect was that nearly a month after he left the Refining God Pool, the pool water, which had been calm, suddenly churned and swayed, and the monstrous waves rose into the air, as if some strange giant beast was breaking through the water in the pool.

Yun Yu, after trying all the means and secret techniques he could think of, did not find a single means that could invalidate the strange aura wrapped in the bones of the ancient dragon beast.

But with his tenacity, he didn't really give up the unavoidable treasure in front of him.

This kind of treasure that is already beyond the scope of heaven and earth treasures, even if he cultivates to the top realm, it is difficult to say that he can encounter it again.

If he misses it, he will regret it for the rest of his life. After repeated attempts, Yun Yu already knew in his heart that even if this kind of top-notch divine beast fell to death and turned into white bones, it was still not someone else who could plot its bones at will.

The only thing that was beneficial to Yun Yu was that the skeleton of this ancient dragon beast had no attack power for unknown reasons.

And that kind of power that has a powerful turbulent effect on the monk's flesh meridians and divine souls, Yun Yu is no longer much of a threat to this at this time.

As for the majestic spiritual power and soul energy consumed in such a situation, under the full reserves of Yun Yumin's unusual cultivation, there was almost no danger.

Just ten days after Yun Yu stopped his body and sat quietly and meditated, he suddenly opened his eyes, and under the glint in his eyes, his hands suddenly pinched.

The spell in his mouth spewed out, and a bright colorful glow of light immediately appeared in front of him, and the spell and consciousness in his hand commanded the energy in his body to surge, and quickly merged into the shield formed by the colorful glow around him.

In an instant, the area within a radius of several zhang was shrouded in the colorful glow shield that overflowed from the surface skin of the cloud feather.

What made Yun Yu extremely happy in his heart was that under the contact between the dazzling glow and the strange aura that wrapped the bones, it was not melted by the strange aura.

Seeing such a situation, Yun Yu still hesitated at all, stretched out his palm and began to condense the colorful glow, and then struck out.

The brilliant glow of several zhang was condensed into a beam of light, directly enveloping the two pillar-like bones in it.

But to Yun Yu, who had not yet been completely surprised, his expression was once again stunned, and the brilliant glow formed a pillar of light rope, and failed to land on the blurred bones in the distance.

And just by entering the range of the strange aura that is difficult to detect, you can't enter a single bit.

Faced with such a situation, Yun Yu, who was originally very happy to take the bones, once again did not have the slightest smile.

What he performed at this time was that he combined the three body cultivation techniques, and then formed his own body practice method, the Cloud Empty Cover Body Exercise.

Yun Yu has been practicing this technique since he got this body, but he only uses the Cloud Sky Cover Body Technique to form the innermost layer of the body to protect the body, and it is to strengthen the meridian blood veins and strengthen the body all the time.

When Yun Yu was unable to solve the secret techniques of many means, he thought of this kind of body cultivation method, because it contained the power of the dragon yuan of this body.

Will the energy of the Buddha-figure of this ancient dragon beast have a close kinship or be effective? It will not lead to its rejection and absorption.

But Yun Yu didn't expect it to be effective, but just meditated on the method of sacrificing the condensation, and wanted to try more.

At this time, although the energy of the body cultivation method infiltrated by the power of this dragon yuan had some effect on the strange aura emanating from the bones, it had not yet reached the point of completely ignoring it.

The soul power in his body was rapidly mobilized, and he rushed towards his eyes, and his eyes flashed wildly.

After a while, Yun Yu's solemn expression was finally relieved, although the rope formed by the Cloud Void Cover of the Body Refining Technique could not completely penetrate the invisible wall cover formed by the strange aura.

However, under Yun Yu's Exploration Void Spirit, he still found that the source of the bright glow strong rope was trying his best to smelt that layer of strange aura that was difficult to see with the naked eye.

"Hmph, Yun wants to see how long that strange aura can block Yun's attack energy. ”

Yun Yu's expression flashed with ruthlessness, and a sense of tenacity immediately filled his heart. How majestic Yun Yu's body's spiritual power reserves were, of course he knew it himself.

In addition, he also has a large number of top-level replenishment elixirs and high-grade spirit crystals, and he also has a cloud sky spear, which has absorbed a large number of thick spiritual power sources for more than a hundred years.

Although that layer of aura shield was extremely majestic and thick, Yun Yu was sure in his heart that as long as it took a certain amount of time to completely penetrate it, he should be able to do it.

With both hands pinching, Yun Yu sat cross-legged again, and began to drive the rope light pillar formed by the secret technique of the Cloud Sky Cover Body with all his heart to condense.

What he didn't expect was that this time, the newly created way to drive the dragon beast bones was in recent years.

In this year, the Yuan spiritual power consumed by Yun Yu has already consumed four times the power of reserves, if it weren't for his rich net worth, and he obtained a large number of top-grade spirit crystals in the wilderness to replenish it, just relying on the Yuan Power in the Cloud Sky Spear, he would have no spiritual power to sacrifice at this time.

Even if there was enough Yuan Spiritual Energy to support it, if Yun Yu didn't have a tenacious mind, it would definitely be impossible for him to hold on for so long.
