Although the Indefinite Rune ranked last among the top ten runes, its power was not to be underestimated, even if Shi Feiyu's current cultivation was not able to use the true rune origin, but with just a shadow, it was definitely not something that a strong person like the black-clothed old demon could resist.

The transparent spell instantly expanded, turning into a mystical spell several zhang in size and enveloping it, and the powerful coercion emanating from it directly descended on the origin of the black-clothed old demon's divine soul.

Such a terrifying spell, the old demon in black has not only never seen it with his own eyes, but has never heard of it. Shrouded in the shadow of the uncertain rune, he suddenly felt a constant roar in his mind, and even his own divine soul origin was about to shatter.

Such a scene immediately made the old demon in black feel horrified, and roared violently: "Little beast, what kind of charm are you using?"

At this moment, the black-clothed old devil didn't know how to describe the horror in his heart, his eyes were wide open, staring at Shi Feiyu deadly, waiting for him to give an answer.

However, a sneer full of banter came out of Shi Feiyu's mouth: "A spell that can kill you." ”

As he spoke, he saw one hand open, slightly pressing against the uncertain rune in the air. As his palm pressed down in the air, the huge spell suspended on the head of the black-clothed old demon also slowly fell with a powerful coercion.

At this moment, the Divine Soul Origin in the old demon's body trembled violently, and immediately burst out with powerful Divine Soul Energy. However, before this divine soul energy could spread, he was imprisoned by the indefinite rune shadow.

Click, click...

Suddenly, fine cracks appeared on the hard rocky ground under his feet, and with their appearance, the face of the black-clothed old demon also changed suddenly.

This coercion from the spell, even some Condensation Realm powerhouses dare not regret it, if it hurts the origin of the divine soul, even he is afraid that it will be difficult to survive?

Thinking of this, the black-clothed old devil's face became hideous, and he immediately raised his head violently and roared: "God-damned little beast, even if the old man fights to die today, he will take your life." ”

As soon as the roar fell, his eyes completely turned pitch black, and a violent aura surged from his body, shaking the black robe on his body.

Shi Feiyu originally just wanted to temporarily suppress this old demon with the help of the Uncertain Rune Shadow, and wait until he got the Nether Blood Lotus to clean him up.

It's just that I didn't expect this crazy old devil to do whatever it takes to make him pay the price. At this moment, seeing the violent aura emerging from his body becoming more and more vigorous, Shi Feiyu's face couldn't help but sink slightly, and the palm raised in the air was also decisively pressed down.

Rumble...

The moment the indefinite rune shadow fell on the black-clothed old demon, a terrifying energy immediately exploded. Everyone found that the sinkhole was shaking violently, and the surrounding stone walls seemed to collapse at any time.

A deafening roar erupted suddenly, but in the shadow of the uncertain rune, a powerful divine soul attack erupted.

Divine soul energy continued to wrap around the black-clothed old demon, making his face also pale. Since becoming the protector of Jiuyin Mountain, it was the first time that the black-clothed old demon had encountered this kind of wolf situation, and he was bombarded with strong attacks one after another, which made him feel frightened and full of anger at the same time.

You must know that even if you have been troubled by the Demon Heart for more than 30 years, you have never had such a humiliating time. The corners of his eyes twitched slightly, and he saw him being pressed under the shadow of the uncertain rune, staring at Shi Feiyu with a gloomy look in his eyes, and laughed loudly: "Okay, very good, you forced me." ”

With that, a violent aura suddenly surged out of his body, and his clothes were shattered. And the black-clothed old demon's tightly guarded mind was also instantly invaded by the heart demon, and his body gradually stood up under this violent aura, and then slapped out with a palm.

Bang...

The shadow of the uncertain rune that shrouded his head immediately exploded with a bang, and immediately dissipated into rolling waves. Such a scene suddenly made Shi Feiyu's pupils suddenly constrict, and he felt even more shocked in his heart.

I didn't expect that this old devil would be able to shatter the indefinite rune shadow with all his might. For a moment, his heart was full of solemnity, if this old devil went crazy at this moment, I am afraid that none of the people present could stop him.

"Death..."

A voice full of gloom and coldness suddenly pulled his mind back, and he saw a violent aura surging around the black-clothed old demon, and his body appeared nearby like electricity, and then his five fingers were like claws and went straight to his head and grabbed it.

Such a familiar move immediately reminded Shi Feiyu of the Soul Snatching Claw used by Jiang Yan, a disciple of Jiuyin Mountain, some time ago, and his face couldn't help but change slightly, and he hurriedly dodged and retreated.

However, the speed of the black-clothed old demon was far above him, and although his feet retreated, the ghost claws attacking from the opposite side were getting closer and closer. Seeing that this move could not be dodged, Shi Feiyu's footsteps suddenly stopped, and he was about to be urged by Yun Tianzhu.

Airplanes...

At the moment when the sharp ghost claws were about to land on his head, a layer of pale golden light curtain suddenly emerged from Shi Feiyu's body, and immediately turned into a thin light shield to envelop him.

"You ......" saw that he was about to succeed, but he never thought that there would be another accident, and at this moment, the old devil in black actually had the urge to vomit blood.

The little guy on the other side made him feel helpless after living for decades. It's just such an endless stream of methods before, just now it was clear that he was in a desperate situation, why did this kind of change occur?

He was already trying his best to suppress the demon's heart, but when he was hit like this, his mind immediately broke and went crazy, and his face gradually became extremely hideous.

"Shura Net..."

Unexpectedly, just when the black-clothed old demon went mad because of this, and the qi and blood in his body were tumbling endlessly, Shi Feiyu's palm suddenly spread out, and a blood-colored net shrouded him in front of him.

Even he didn't react to such a change, and when the blood-colored net shrouded him, the black-clothed old demon seemed to wake up violently.

The figure was like electricity, and disappeared in front of everyone's eyes in an instant with an afterimage. When the Shura net shrouded down, it was empty, and there was no trace of the black-clothed old demon.

"Looking for death..."

At the same time, a yin sound also came from behind Shi Feiyu, and before he could turn around to respond, the palm that had always contained the source qi of rage slapped him on the back fiercely.

Rumble...

Immediately afterward, everyone saw Shi Feiyu's body fly out like a cannonball, and in the blink of an eye, he slammed into the opposite stone wall.

"Brother Feiyu..."

Seeing this, Meng Yuqiao's face was full of anger, and with a fierce one-handed guidance, the Coiling Dragon Golden Seal immediately smashed towards the black-clothed old demon with an oppressive wind.

But in the face of this coiling dragon golden seal, the old devil did not have the slightest fear on his face, he just sneered, and then clenched his fists, and a fierce punch exploded.

Boom...

After the deafening noise, Meng Yu found that his Coiling Dragon Golden Seal was actually shocked and flew high, and immediately fell into the Netherworld Blood Pool with a bang.

"Little girl, you should die too. ”

At this moment, the black-clothed old devil was obviously invaded by the demon heart, and he only knew killing in his heart. The palm of his hand poked out, grabbed Mengyu as soon as he grabbed it, and immediately threw it at the opposite stone wall.

With a muffled bang, her delicate body suddenly collided violently with the hard stone wall, which also made the qi and blood in her body tumble endlessly, and blood spurted out wildly.

"Senior Sister Mengyu..."

Seeing this, Shen Ziyi's apricot eyes widened, and she screamed violently, wanting to step forward and make a move. Unexpectedly, the black-clothed old devil took the lead, and when she spoke, her palm, which was like a ghost's claw, came closer, and immediately threw Shen Ziyi towards the opposite stone wall.

Immediately afterwards, Zhou Lian, Shen Zifeng, and Chang Fu were seriously injured one after another, but the old devil ignored them who were injured and fell to the ground, but raised his arms high, raised his head and laughed: "The old man is invincible in the world, the old man is finally invincible in the world, hahahaha......"

Such a scene made Shi Feiyu and the others stunned, this old guy was fine just now, why did he suddenly go crazy? However, they didn't know that the black-clothed old demon, who had been plagued by the inner demon for more than 30 years, was already on the verge of collapse, otherwise he would not have risked his risk to enter the Dragon Soul Mountain Range to find the elixir.

Previously, he was repeatedly attacked by Shi Feiyu's endless methods, and finally was completely invaded by the demons in his heart, and thus became insane. A junior whose cultivation is far below himself has actually let himself suffer three or four times, how can such a blow be borne by the narrow-minded black-clothed old devil?

Everyone watched him stand there, looking up and laughing wildly, and their faces became strange. Shen Ziyi leaned against the stone wall and coughed violently, as if she wanted to say something, but Shi Feiyu shook her head at her.

Now this old devil is unstable, if he is stimulated a little, I am afraid that he will kill himself and others, and it is better to stay away from him as far away as possible at this time.

It's just that the Netherworld Blood Lotus is still on this old devil, and Shi Feiyu is also unwilling to leave like this, in case he eats or damages the Netherworld Blood Lotus, he will lose this once-in-a-millennium heaven and earth spiritual object.

"Wait here. ”

His eyes narrowed slightly, and he seemed to have an idea in his heart, Shi Feiyu commanded, and immediately stood up and walked towards the black-clothed old demon. Although he was blown away by a palm before, he had the Yuntian bead body protector and was not injured.

"Who?"

In the midst of the wild laughter, as if sensing someone approaching, the black-clothed old demon's face changed, and he suddenly shouted angrily. And Shi Feiyu's playful voice also sounded: "Who are you?"

This approach made Mengyu and the others full of doubts, obviously unable to guess how he was going to deal with this crazy old devil.

"The old man is the first in the world, and the black-clothed ...... of Jiuyin Mountain" frowned slightly, the black-clothed old devil seemed to be a little unable to remember his identity, lowered his head and thought for a while, before he shouted angrily: "No, the old man is the first in the world in Jiuyin Mountain..."

Such an upside-down answer made Shi Feiyu more and more sure that he had become completely crazy, and the corners of his mouth couldn't help but show a wicked smile, and then whistled in a joking voice, and asked: "Is it the first in the world in Jiuyin Mountain, or the first in the world in yourself, or the first in the world of the black-clothed old devil, which of the three of you is more powerful?"

Such an awkward question immediately made the black-clothed old devil stunned in place, his face turned from blue to red, and then from red to white, and after thinking about it, he still couldn't tell it clearly, and couldn't help but say angrily: "What's the matter with you, who are you?"

Seeing this, Shi Feiyu sneered in his heart, and immediately raised his head in front of everyone and sighed: "Good apprentice, don't you even know the old demon in white who is a teacher?"

"Poof..."

Mengyu, who was waiting, immediately burst out laughing when he heard this......
