Looking at the animal skin paper in the wild flames on the altar of the underground palace, Lin Yunxin thumped and calmed down after a while.

Accompanied by the power in the divine rune, it spread out quietly in this space, and the soul imprint in Lin Yunxuan's palace trembled, absorbing all the breath from the divine rune.

Immediately, Lin Yun felt that the soul imprint had grown a lot invisibly, and a dry heat spread in the body.

In an instant, Lin Yun's internal organs, flowing blood, and the skin on his body were faintly hot.

"This……"

Lin Yun clenched his palms tightly, and there was a deep look of surprise in his eyes.

Just in the depths of the space illuminated by the divine runes, his soul power and true essence are faintly increasing, which is quite mysterious. For Lin Yun, who was stuck in the Yin Profound Realm, it could be described as a nectar meeting after a long drought, which was quite amazing. Mo Ling glanced at him and said with a smile: "I feel it, the fire attribute power contained in this divine pattern is quite majestic. It is like the sun, nourishing this space, even if you do nothing, you can be here. Get a lot of overflow. True essence, soul power and physical body can be tempered at the same time

Refinement. "

"It's really mysterious."

With a smile on Lin Yun's face, he replied softly.

"Although the power of this Divine Rune is extremely mysterious, you should also feel it. You can't stay here for a long time. Over time, it's easy to get burned. Don't get too close. If you don't cultivate enough, it will turn to ashes in an instant. The power of this Divine Rune is quite domineering and does not distinguish between enemy and me."

Mo Ling looked solemn and said solemnly.

Lin Yun nodded, he could feel that the other party did not lie.

"This jade slip is for you. You are here to watch it. If you can't bear it and withdraw, don't be brave."

Mo Ling handed his jade slip to Lin Yun, and after another serious exhortation, he slowly retired.

Soon, in the empty space, only Lin Yun was left alone.

Looking down the steps and looking at the flames on the altar of the underground palace, Lin Yun looked very solemn.

When he lifted his leg and stepped down, he suddenly felt his body suddenly sink. This step leading to the underground palace has a great coercion, which makes people bear the burden of a green mountain.

Under such coercion, Lin Yun's steps were difficult, and every step was particularly difficult. Gritting his teeth and turning the Ziyuan Sword Art to the extreme, Lin Yun resisted the pressure and walked down the stairs step by step.

In the short distance of less than a kilometer, Lin Yun walked for nearly half an hour, sweating profusely, and almost collapsed.

When the footsteps finally set foot on the underground palace, the pressure suddenly soared, Lin Yun thumped, and knelt on one knee on the ground.

Sweeping his eyes to the four directions, the power of the Divine Runes that pervades the underground palace has been condensed into substance, turned into a pale yellow gas, and contains an indescribable terrifying pressure.

This was just the edge, Lin Yun estimated that he was still about a thousand meters away from the altar. Within a hundred meters of the altar, the core area was brightly golden, like a golden lake made of flames.

No wonder Mo Ling said that Mo Ran approached and would be burned to ashes in an instant.

The ancient Divine Runes are indeed a bit bizarre and contain too many mysteries. It is hard to imagine that the golden age of martial arts would suddenly be destroyed, leaving only a piece of ancient monuments for future generations to pay their respects.

call!

Spitting out the long turbid air, Lin Yun gritted his teeth and shouted angrily, standing up with great difficulty.

"I can't move forward. It's my body that is amazing, and it's someone else. If I'm so cultivated, I'm afraid I won't be able to get out of the steps at all, so just practice and observe here..."

Lin Yun's eyes, through the dark red airflow in the air, stared at the animal skin paper in the center of the altar flame.

On the ancient animal skin paper, mysterious golden lines are imprinted, which is obscure and difficult to understand. Suddenly, he felt a force of destruction coming towards him, and the mysterious lines seemed to be like a purgatory composed of golden flames, trying to devour and refine people's hearts.

In the blink of an eye, Lin Yun felt unable to hold on any longer, and closed his eyes quickly.

After calming down for a long time, he slowly opened his eyes, but he did not dare to focus on the altar rashly. The boy's brows furrowed slightly.

"This divine pattern is quite similar to the sword that the man in Tsing Yi broke out of. If I can't be afraid of the power of this divine pattern, I will definitely be able to withstand the sword that broke out of the painting. Don't worry, this place is all over the place. The power of the divine rune can be refined first, and after the spirit power has been refined, try it again..."

At the moment, Lin Yun sat cross-legged, his mind moved slightly, and a silver purple iris bloomed from the ground. The power of the divine runes that pervaded all around suddenly surged.

boom! With the influx of such powerful divine rune power into his body, Lin Yun's body suddenly vibrated, and the surging divine rune power was like a molten molten flame condensed, infiltrating his limbs, bones and internal organs. The skin all over his body was fiery red, and he could clearly feel the true essence, soul power, and bones.

, the flesh and blood is madly and greedily absorbing the power of this divine rune at this time.

Like a moth to a fire, he is reckless.

The burning pain immediately spread all over the body. Even if you don't do anything here, you will feel a little bit of pain, not to mention the crazy power of devouring the Divine Rune.

Buzz!

Under such violent power, the silver purple irises in the Zifu trembled, as if there were signs of a breakthrough.

Lin Yun's heart suddenly moved, and then he was ecstatic.

This Ziyuan Sword Art was stuck at the peak of the ninth level, but it had been a long time, even if the Xuanyin Flower was refined once, there was no movement at all.

Right now, it was like a trembling sword, which was an unexpected joy.

If he could take this opportunity to break through to the tenth level of the Ziyuan Sword Art, there is no doubt that Lin Yun's strength would increase dramatically.

But at the same time, Lin Yun remembered Mo Ling's advice, don't wait for a long time at this moment, it will burn to ashes if you are not careful.

Once you are immersed in the practice and completely forget yourself, it is very likely that you will miss time.

Bet!

But in the blink of an eye, Lin Yun had a decision in his heart, if he could really break through. The tenth-level power of the Ziyuan Sword Art will definitely suppress this violent divine rune power and keep the body from being covered.

Moreover, his Dragon Elephant Fighting Body Art has already reached its peak, and it is not comparable to the fleshly bodies of those profound masters.

Once you miss this opportunity, you don't know when you will wait.

The further back the Ziyuan Sword Art was, the more terrifying its power became, and the ninth level of the Sword Art was at its peak so that he could compete with Xiaocheng in the Yang Profound Realm. If the sword art breaks through the tenth level, his Ziyuan sword strength will not be so difficult to face the Yang Profound Realm Dacheng.

"Then do your best and have a shot at this blog!"

Pay attention to make up, Lin Yun is not hesitant at all, the silver purple irises in the purple mansion suddenly bloom, and the power of the divine rune is continuously devoured.

In the empty underground palace, Lin Yun sat cross-legged, refining the power of the divine runes that filled the place.

Boom!

Under his frenzied refining, the flame aura derived from the power of the divine rune exploded one after another, bursting with thunderous noises. In the passage of time, Lin Yun's body was bathed in a golden flame.

From a distance, it looks like a sword bathed in divine light, with an indescribable edge permeating its entire body.

He is like a sword embryo, being tempered by the flame of the recipient, and it is the power of the fire attribute divine rune from the ancient times. In the flames, crisp sword chants came from time to time, and the silver purple iris flower in the purple house in the body was bright and shining.

Every time it shines, it is like the sword is swallowing the cold light, bursting out with amazing momentum. Under this cold light, even the core area around the altar, the golden lake of brilliant flames, was swayed with ripples.

Click!

As the light shone, the purple iris in the Zifu had a heaven-shaking sword sound, and the bottleneck of the ninth-level sword art was finally broken. The silver purple irises had grown to eighty-two at this moment. Although there was only one more, the cold glow that filled the purple irises had undergone earth-shaking changes.

In the blink of an eye, a boundless chill swept out, extinguishing the flaming golden flames on his body.

Lin Yun breathed a sigh of relief, if this sword art could no longer be broken through, his physical body would really be unable to bear it.

Under the blessing of eighty-two purple irises, the silver real essence at the purple mansion filled the whole body with a single thought. That stern aura, like a sword-like edge, was more than twice as strong as before.

Not only that, when Lin Yun's original essence was condensed by Qiankun Biyun Dan, it was supplemented by the power of this divine rune. It became vast and thick again, and under such a back and forth, his cultivation base suddenly became as thick as a mountain.

Thinking about it carefully, he entered the Purple Mansion, but in just two months, he reached the incomparably exaggerated Yin Profound Realm Consummation.

With such a heaven-defying cultivation progress, even if there is a Ziyuan Sword Art in charge, to be honest, the hidden danger is not small. On the road of cultivation, one is most afraid of rushing in and going into the devil, but now these hidden dangers are completely eliminated.

If I go to activate the Ziyuan Sword Art, I can at least reverse eight laps, and even nine turns into one, it may not be impossible.

Lin Yun's tightly closed eyes slowly opened, and in an instant, two bright rays of light rushed out like sword lights, tearing apart the power of the divine runes that permeated the air.

But for a moment, this kind of brilliance quickly dissipated, but the sharpness in the depths of his eyes lingered.

hum!

Lin Yun got up slowly, the majestic pressure he felt before was obviously much lighter. At the moment of getting up, there was a crisp sword sound coming out of the body at the same time, extremely light. Those sword sounds were emitted from the petals at the Purple Mansion when they touched each other after the tenth level of the sword art.

Accompanied by these continuous sword sounds, the true essence in Lin Yun's body surged.

"Ziyuan Sword Art, really powerful!"

Lin Yun clenched his fingers tightly, feeling the power coming from the Zifu, and a sharp edge appeared in his eyes. The breakthrough of this Ziyuan Sword Art not only made its own true essence go further, but also the soul imprint in the mysterious palace is also much more powerful.

Invisibly, the sword power contained in his eyes skyrocketed a lot. He swept his gaze and landed on the animal skin in the flame of the altar, standing still, staring at the lines branded in it. But for a moment, the mysterious pattern once again evolved into a terrifying purgatory composed of golden flames, with the power of destroying the sky and the earth, rolling in, as if even its soul

The soul can be burnt out.

But this time, Lin Yun didn't close his eyes, the sword power that lingered in the depths of his eyes suddenly burst out.

Click! This terrifying purgatory was abruptly cut through a crack by this sword power. The corners of Lin Yun's mouth were slightly upturned, and he walked slowly towards the altar.
