On the top of the mountain, the wind howled.

Lin Yun sat cross-legged, looking at the drop of Canglong blood in front of him, thoughtfully.

The blood essence the size of a grain of rice contains astonishing energy, and such astonishing power can make people feel terrified just by looking at it.

"what?"

A strange color suddenly flashed in Lin Yun's eyes, looking a little surprised.

In the four directions of the blood essence, there is a vague aura that wraps it in it. If you don't look carefully, you won't be able to feel the blood essence even if you put it in the palm of your hand.

After thinking for a moment, Lin Yun estimated that this mysterious aura might be a protective film.

Just like many medicinal herbs, in order to prevent the medicinal power from evaporating, a layer of beeswax will be coated on the surface to prevent contact with the air. After all, in the air, in addition to the spiritual energy, there are also many filthy auras, which make the loss of medicinal power small and damage the medicinal properties of the medicinal pill.

The panacea might also become the poison for this murder.

As for the Canglong blood in front of him, there must be some means for it to be preserved in ancient times to the present.

call out!

Lin Yun's eyes suddenly flashed a gleam of fineness, and the right hand on his knees flicked his fingers. A ray of silver sword light pierced through the void and flew towards Canglong's blood.

When the sword light was about to stab the Canglong blood, a strange thing happened. The sword light was swallowed by the invisible conjunctiva around the Canglong blood, and then burned into a silver flame.

When the real essence in the sword glow was completely burned out, the blood of the blue dragon floated quietly in front of him, as if nothing had happened.

"Something interesting..."

Lin Yun whispered to himself, it seems that it will take a lot of effort to refine this Canglong blood.

Clang! Keng! Clang! Clang!

His mind moved slightly, and between his fingers, strands of silver sword lights kept stabbing past. But without exception, all of them burned as soon as they approached, and in the blink of an eye there were hundreds of sword lights, all of which were lost.

"Can't you?"

Lin Yun frowned slightly, snorted coldly in his heart, he couldn't believe that even the conjunctiva couldn't be broken.

boom!

The peak of the consummate innate sword intent foundation, there is a loud sword sound that erupts in Lin Yun's body, resounding in the sky, the clouds move in all directions, and the sky and the earth are pale.

On the young man, a majestic coercion suddenly erupted, and the sword intent blended with the sky. There seems to be a great power between the light dance of the hair, affecting the turbulence in the ten-mile radius.

laugh! laugh!

Waiting for the vast and fierce sword power, the Canglong blood in front of Lin Yun trembled violently. The next moment, a black flame ignited, and the mysterious conjunctiva wrapped in Canglong's blood was being destroyed bit by bit under the pressure of the consummate Innate Sword Intent.

Boom!

When the black flames were burning, there were boundless thunderclouds in the sky, and they quickly gathered together under the agitation of gusts of wind. In the blink of an eye, the top of the mountain was gloomy, and every now and then, astonishing lightning pierced through the sky.

"This kid, what did he gain from the Xingjun Ancient Tomb?"

In the distance, the old ghost Youyun hiding in the dark, saw the vision on the top of the mountain, and his face became completely solemn. In the depths of his eyes, a strong greed flashed.

I thought this kid just got the Sky Bead, but now it seems that the harvest is quite amazing.

Tianxingzhu, he didn't care much at that time, he had already passed the yin and yang realm. If he can get it, he can only change his hands to exchange for other valuable treasures that can help him advance to Heavenly Soul.

But even a fool can see the vision in front of him, what Lin Yun has refined is astonishing.

"It doesn't matter what you are, I will kill you later, and I will be clear."

The old ghost Youyun had a cold look on his face, and the murderous intent surging in his eyes was even more ferocious.

Lin Yun was cautious enough. After his injury was healed, it took him half a month to start refining Canglong blood. It's a pity that he ran into this old ghost Youyun, who chose to assassinate Lin Yun with his perfect cultivation in the Yin and Yang realm.

Such a temper, like a poisonous snake hiding in the dark, is completely defenseless.

Now he is concentrating on refining Canglong's blood, no matter how vigilant he is, he will take a lot of attention away. If you want to prevent the sneak attack of the old ghost Youyun, there is almost no possibility, and you will die and die.

But a strange thing happened, just as the old ghost Youyun took a step, the smile on his face froze.

The soles of the feet that fell were pulled back little by little.

The moment he lifted his foot, a sneer sounded in his ear, this smile had no sign at all, and scared him half to death.

He retracted his feet, his perception spread out, his eyes wandered around, desperately looking for the person who wanted to find this laugh.

But there is absolutely no trace, and the laughter just now was in his ear. The distance is so close at hand, he can search for his perfect cultivation of Yin and Yang, but he can't find anything.

hallucinations?

Surprised, Old Ghost Youyun's eyes flickered, and he stepped forward again with his retracted foot.

"Humph!"

But as soon as he stepped out, a cold snort sounded, which made him shrink back in a moment, and his mind was shocked.

What kind of cultivation is this, even the terrifying powerhouse of the Heaven Soul Realm cannot hide his breath in front of him. Moreover, he has not never fought against the powerhouses of the Heavenly Soul Realm before, relying on the ghost method, it is enough to save his life.

The more you think about it, the more terrifying the old ghost Youyun is, the cold sweat on his forehead keeps falling down.

damn...

Which fairy did you offend?

"Former... Senior, who is the master."

The old ghost Youyun had offended many people in his early years, and suddenly he felt inexplicably fearful in the depths of this situation.

"It doesn't matter who I am, the important thing is that you can't move this person... Although I don't like seeing this kid, it's not your turn to do it!"

An old voice echoed in all directions, and between the echoes, the old ghost Youyun was completely panicked. At this moment, he felt that the mysterious person in the dark seemed to be everywhere, no matter where he turned, there was the existence of the other party.

"I'm leaving now, swearing that I will never do anything to this person again."

In a panic, the old ghost Youyun answered in a deep voice.

"late."

What responded to him was a ruthless and indifferent voice, and there were faint ripples in the square space. The old ghost Youyun opened his eyes and looked, and was horrified to find that the ancient tree supporting the sky in his field of vision was twisted for no reason.

In the distorted space deep within him, he couldn't move, and his heart was suddenly filled with fear.

Bang!

Before there was time to react, in the space where all things were distorted, a star suddenly bloomed. Immediately after, a hand fell on top of his head, and his body instantly softened, turning into a bullet of blood.

call out!

When the owner of the hand fully appeared, the square space became clear and bright, and an old man in sackcloth walked out.

In the territory of Youzhou, the quite vicious old ghost Youyun died just like that.

If Lin Yun was here, he might have some impression of this old man. That day, when Su Ziyao ascended the throne in the Daqin Palace, he was like a mountain in front of Su Ziyao.

When he raised his hand, there was an invisible palm that shattered Lin Yun's sword, and knocked him down from the ten thousand steps several times, embarrassed and miserable.

Whoa! At this moment, many terrifying dim lights suddenly rose from the blood of the old ghost of Heiyun's death. Those dim lights are like evil spirits in hell, fierce and terrifying, and others will tremble with fear when they see it. But such evil spirits, the moment they saw the old man, were immediately frightened.

Sharp screams, scattered away.

"Ghost cultivator? There are quite a few evil spirits that this old guy cultivated before his death..."

The old man in linen glanced at random, waved his long sleeves, and these many resentful souls instantly turned to ashes. He stood with his hands behind his back, staring at the top of the distant mountain, shrouded in a thundercloud, on Lin Yun's body with lightning flashes all over his body.

When he saw the burning black flame in front of him, a strange color flashed in his eyes.

"Netherworld fire?"

The old man in linen was a little surprised that such strange things could be seen here. Netherfire is a flame between the virtual and the real, and it is a rather rare and strange fire.

What's in that flame?

The old man in linen, who didn't intend to stay longer, suddenly became interested, and he stared at it. The scene dozens of miles away suddenly became clearer in his eyes.

"Blue dragon blood!"

The sackclothed old man let out a soft cry, just now he understood.

This kid is also a strange person, and he actually destroyed this fire with the sword intent of peak perfection. But on second thought, with his cultivation base, there is no other way, he can only be so reckless.

What is it called, it seems to be Lin Yun, right... At such an age, being able to cultivate sword intent to such a level is indeed a bit extraordinary.

The old man thought to himself, looking at the young man under the thunder cloud, his unsmiling face showed a little more appreciation.

"However, this is a drop of pure Canglong blood. How fierce is Longwei. If he doesn't rely on foreign objects and no elders to help him, it would be difficult to refine and contain it based on his physical body."

The old man in linen who was observing secretly seemed to have forgotten to leave, but a strong interest appeared in his eyes.

Can this kid really subdue this drop of Canglong blood?

With his current cultivation base, it is definitely not enough.

The old man in linen murmured softly, but for some reason, he felt that something unexpected would happen.

"Let's see for a moment, you are the most outstanding saint in the Emperor Xuan Palace, how capable you are!" The old man in linen looked awe-inspiring, and made up his mind not to leave for now.
