The power of soul power detection scanned continuously, enveloping tens of thousands of miles around his body from time to time, and Yun Yu's expression also changed slightly.

The core of this Demon Soul Secret Domain, because there is a Yin Spring in its center, there are a large number of low-level Demon Souls in the surrounding area, and there are even a large number of Yin Qi Transformation Phenomena.

These Yin Qi spiritual objects that form a round ball are floating around, and where there is Yin Qi energy that is thicker, there will definitely be a large number of Yin Qi spiritual objects condensed there.

This batch of Yin Qi spiritual creatures, which are innumerable, only through instinct, constantly wandering in the Yin energy to advance, and finally by chance, a trace of vitality is generated, and the demon soul is formed.

However, once it was formed into a demon soul, it was repelled by the Yin attribute energy of this place, and began to pull these low-level demon souls that formed a demon soul out of this area.

Looking at the weak bodies scattered around within the scope of the soul power detection, Yun Yu suddenly felt as if he had entered the legendary ghost realm, and in this case, only the mortal ghosts in the ghost realm were similar to what he saw in front of him.

Yun Yu's primary target for entering the Demon Soul Secret Domain came to this place, and it was precisely because he heard the rumors of this place that he guessed whether there would be a passage to the ghost world at the bottom of the Yin Spring, and the other was also extremely interested in the Yin attribute Yuan spiritual power in this place.

After nearly twenty days of sneaking in, Yun Yu had already felt that the Yin Mist around his body contained the kind of Yin Attribute Energy contained in it was much thicker.

And the number of Yin Soul bodies wandering around was suddenly greatly reduced.

Standing on top of a tall mountain peak, Yun Yu's soul power probe was released, reaching out to the place covered in dense fog in front of him, and his expression became a little more cautious.

By this point, we had undoubtedly reached the center of the entire area, not far from the place where the Yin Fountain gushed.

Being able to make the powerful cultivators of the Demon Venerable in the Demon Soul Secret Domain is a place that is very jealous, although he yearns for it in his heart, he will not rush forward recklessly under impulse.

After flying slowly again for tens of thousands of miles, the surroundings were already covered with gray and thick mist, and there was no longer any yin spirit.

This made Yun Yu, who had always been quick-witted, also puzzled, and many high-level demon souls who were captured by him all said that the place where the Yin Spring gushed was the birthplace of the demon soul's predecessor body in the Demon Soul Secret Domain, but the situation in front of him made him puzzled.

The lonely figure flew away in the dense fog of the tall mountains, the dense mist breath drifted and rolled in the mountains, cold and cold, and the surrounding mountains were strange and empty, making people feel a dead and silent atmosphere.

Sensing that some of the Yin attribute energy in the gray and white dense fog was becoming more and more intense, although Yun Yu was excited in his heart, he felt like he wanted to stop and absorb and cultivate.

However, up to this time, the situation in this place has not been discovered, and it is not known whether this kind of Yin attribute energy is "pure", so I have thought about it again and again, or move forward again.

As its body flew inward, the feeling of the pure energy that terrified the Demon Soul Cultivators did not appear.

Seeing that there were no longer any demon souls and bodies around him, Yun Yu was puzzled in his heart, and he had already made sufficient preparations at hand.

Being cautious in everything is the first guarantee for Yun Yu to be able to escape after experiencing many dangers.

This time, his cautious approach paid off again.

Just as Yun Yu was slowly flying forward with the light of escape, his heart suddenly became vigilant, and under the full force of his soul power detection, his body suddenly stopped at the edge of a valley.

The small valley in front of him did not show the slightest difference from other places, but Yun Yu's eyes flashed with blue light, and his expression showed a serious color.

"How did you find out that the old man is here?" The old man thought that he could already hide his own breath without leaving any of it, and he could even make you aware of it, which was really surprising to the old man. ”

When Yun Yu's gaze looked at a place on the edge of the valley, and his gaze and body did not move, suddenly a slightly surprised voice of familiar words suddenly sounded in the place where Yun Yu's gaze was focused.

Then a dark red mist flashed, and the figure of an old man appeared in the place.

"It's really ghostly, you would have expected what the purpose of Yun Mou's coming was. I really have to make Yun admire the intelligence of you and others.

But why are you the only one here, and where are the other two, you can let them show up, and Yun can't escape anyway. ”

Looking at the old man of the Demon Soul wrapped in the dark red mist in front of him, the different color on Yun Yu's face flashed and disappeared, and he regained his calm in an instant.

He probed the surrounding places, but did not detect the existence of the breath of the other two Boundary Breaking Realm Demon Soul Old Men, and his face moved, and his mouth was full of deceitful words.

The old man of the Demon Soul who suddenly appeared was one of the three old men who were chasing Yun Yu tens of thousands of miles away.

As for which of the three old men it was, Yun Yu couldn't tell the difference, but I was afraid that only they knew it.

The three of them, whether they are in shape or in cultivation, are all the same. No matter how powerful the Cloud Feather Divine Soul Realm was, it was absolutely impossible to distinguish the three of them specifically.

"Heh, the junior can't help but think too high of himself, if he wants to capture a mere Lingzun early stage cultivator of yours, where can he use the other two.

Although your formation attainments are excellent, in the core of the Demon Soul Secret Domain, can you still escape? ”

Under the flickering of his figure, the old man wrapped in dark red mist had already stopped two hundred feet in front of Yun Yu.

"Hmph, whether you can escape or not, you don't know until you have done one. Before, Yun Mou was just temporarily avoiding you and the other three people, and if you wait, only one will come out. Yun had long wanted to comprehend the strength of the Boundary Breaking Realm cultivators.

At this time, you happen to be one, so let Yun Mou see what powerful means you have when you wait for the demon soul to cultivate to the peak of this realm. ”

The essence flashed in his eyes, although Yun Yu was still afraid of the existence of the center at this time, but at this time, the opportunity could not be lost, the other party only appeared, and this was a good place for Yun Yu to look forward to fighting.

It has an abundant Yin attribute energy, so its expression is not without the slightest fear, but has a mentality that is eager to try and fight with it.

The energy in his body shot out, and a layer of yellow-white mist suddenly shrouded his body, and under the attack of his fist, several yellow flashing spirit fist shadows shot towards the old man in an instant.

The other figures were also wrapped in the mist formed by the spiritual power, and fighting with this old man in the Demon Soul Secret Domain, Yun Yu wanted to show his spiritual energy first, and there was a heart that paralyzed the other party.

As he finished speaking, several majestic spiritual power fist shadows flashed towards the old man very quickly.

Sensing the attack spiritual energy emitted by the other party, the old man snorted lightly in his nose, and his sense locked on Yun Yu's figure hidden in the yellow and white shroud, with a hint of casual disregard for the attack on his face.

In the face of Yun Yu's attack, as a demon soul old monster who broke the realm, he would not have the slightest worry, sensing the energy of this attack, and it was only a mid-level monk of the Lost Land Spirit Venerable Realm.

Although in the great rank of the Great Cultivator, the Boundary Breaking Realm is at the peak level, and the gap between the Spiritual Venerable Realm of the early level is not at all the difference between the peak level Great Monk and the first level of the Great Powerful Monk.

They are all able to borrow a trace of the power of the rules of heaven and earth, but when it comes to the power of the rules stored in their own bodies and the familiarity with the power of the rules of heaven and earth, there is still a very obvious gap.

Although his body was wrapped in a spiritual power shield, that is, Yun Yu's self-created cloud sky shield, but with his own divine soul realm not inferior to the other party, Yun Yu still sensed and the old man's powerful perception attached to his body.

When the old man was just standing in place, using his mind to stimulate the diffusion and transformation of the dark red mist of his talisman, and relying on his strength to resist Yun Yu's attack energy, his heart also moved slightly.

If the young monk in front of him reached the late-stage level of cultivation at this time, he would already be able to fight with himself with the strength of this attack energy alone, and he would be in an invincible position.

Unexpectedly, those few attacks that seemed to be issued at random suddenly increased the energy intensity by as much as 30% compared to the previous one, and its striking power was also suddenly doubled.

If this monk was able to continuously unleash hundreds of energy fists with lightning speed, the energy of the subsequent fists would increase suddenly, and it might pose a certain threat to his body.

But at this time, seeing that the power of the fist was only a few blows, and he was able to resist it with only the power of the shield fog he repaired, the old man was not afraid in his heart.

But just when the old man sensed that the other party's strength was not strong, and wanted to sneer, a slight sound of breaking the air suddenly resounded dozens of feet in front of him.

Suddenly there was a feeling of abnormality, and the old man was also a little surprised in his heart, obviously his own sensing power locked on the other party's figure, how did this strange thing start.

With this subtle sound of breaking through the air, a cloud of red light carrying a pound of energy suddenly appeared, and rushed towards his body to flash.

"Hey, I can't think of some means. With a soft voice, a hand was stretched out from the old man's body, and a bright red light appeared in his hand, and a flash of lightning swept away the red light in front of him.

The speed of the two sides fighting can be described as lightning, and in the blink of an eye, several of them emitted their own attack energy and secret techniques.

As soon as Yun Yu approached the valley here, he activated the fire energy hidden in his hand, and first launched the Shining Spirit Fist Shadow, and sent it to the Shining Spirit Fist Shadow, so the old man didn't notice it for a while.

Seeing that the fire energy was frozen in the air by the opponent's counterattack, Yun Yu's mind urged, and the red light suddenly exploded, forming a starry light.

The fire in the body has the effect of destroying the soul, and it has been upgraded to a different fire, and the instinctive attribute is to restrain all the yin soul energy or have a killing effect on the soul body.

Under the blessing of Yun Yu's soul power stimulation and injection, it suddenly turned into starlight, into dozens of little finger-sized points of light, and flew down flexibly, bypassing the old man's counterattack red energy, and went directly towards the old man's figure.
