Behind the stone gate, the aura is rich, almost like substance.

In the spirit stone, the true monarch sat down, and the breath was still there.

The stele stands in front of it, and rows of ancient characters are carved on it.

Chen Yuan swept over, looked at the old man sitting cross-legged, and then there was a faint layer of white ash in the interior of the cave.

"What's the matter with these spirit stone slags?"

Immediately, he turned his gaze, and when he looked at the old man's tightly closed hands, he couldn't help but froze.

"This is the Aggregate Array?"

Chen Yuan looked at the pupils of the old man's hands at this time, and looked around.

I saw that the dense spirit stone kept exuding an almost substantial aura.

These spiritual energies filled the entire space, but they kept converging between the old man's hands, constantly being absorbed and refined.

"Why do you put a Gathering Array between your hands?"

Chen Yuan frowned slightly.

The Yun Pole Array is a kind of Grade Law Array, which is mainly used to breed and protect some top-grade elixirs, so that they can grow better and faster.

At the same time, this kind of magic circle also has some isolation and attack functions.

And this kind of magic circle is extremely difficult to arrange, in addition to its requirements for cultivation, it also has extremely high requirements for the surrounding heaven and earth aura.

In this way, if it weren't for this spirit stone all over the ground, I am afraid that this Yunji Array would not be able to form it.

It was precisely because of the isolation effect of this Aggregate Pole Array that Chen Yuan did not discover the existence of the Aggregate Pole Array at the beginning.

If it weren't for the white ash on the ground that caught Chen Yuan's attention, he probably wouldn't have paid attention to the old man's hands.

After all, this corpse was the corpse of a half-step Yuan Infant powerhouse, and even if it died, that physical aura was enough to deter all Condensation Stage powerhouses.

And the white ash all over the ground was formed by the spirit stone after it was absorbed and refined, and turned into powder.

The spirit stone is transformed by the spiritual energy of heaven and earth, and unless it is absorbed, it is impossible to disappear at all, especially in a place where the spiritual energy is relatively abundant in the ancient realm.

And Xuanyu True Monarch, there are already more than a thousand sitting, and there is no one here who can refine these spirit stones.

So, this caught Chen Yuan's attention.

"Whoosh!"

Seeing this, Chen Yuan's expression condensed slightly, and he hit a golden streamer at Yan Tianqi to protect his body.

He was going to try it and see if he could crack the Aggregate Array.

After all, this Yun Extreme Array was arranged by a half-step Yuan Infant powerhouse, even though he knew the key to cracking this formation, but after all, Chen Yuan's current cultivation was still relatively low, so for the sake of safety, he would protect Yan Tianqi first.

"Condensation!"

Chen Yuan's hands kept sealing, and the essence aura like white mist, in Chen Yuan's urging words, condensed each other, converging into runes.

Immediately after, the three-color divine glow of red ink and gold shot out from Chen Yuan's pupils, blending with the white runes.

In the end, the colorful runes in the sky continued to swim, turning into a three-zhang rune dragon and rushing towards the closed hands of the Xuanyu True Monarch.

"Boom!"

At this time, a roar erupted between the hands of the old man.

The originally peaceful cave was suddenly shrouded in murder.

At this time, Chen Yuan's eyebrows were furrowed, as if he was walking on thin ice, and his hands were constantly changing.

And the three beast kings standing outside the stone didn't dare to move at all when they saw Chen Yuan's movements at this time.

Now, they have long since dismissed the idea of black feather grass.

As the beast king of Tongshen Cliff, the three demon beasts have long been psychic.

At this point, if they still can't see it thoroughly, then these thousand years of penance can be regarded as a vain practice.

In the entire ancient realm, this is the first forbidden place, and all the immortals are killed by the killing array.

But Chen Yuan is walking on the ground here, and he has opened the stone door that no one has ever opened.

In their hearts, they can't afford to have the slightest thought at this time.

Yes, just fear, and the old man's trembling in their veins.

"Broken!"

At this time, Chen Yuan suddenly burst into a loud shout.

"Boom!"

Suddenly, the entire cave seemed to be turned upside down in an instant.

The killing machine in the sky then changed, transforming into a monstrous endless true fire.

These true fires are extremely hot, as if they come from the Xuan Fire above the Nine Heavens, and a single trace can burn the Dao body and melt the soul.

If an ordinary earth immortal is here and feels this breath, the horror will be frightened and lost soul.

The Nine Heavens Xuanhuo is the supreme existence in the True Fire.

Even if the earth fairy is contaminated with a drop, it will turn to ashes.

"Huh?"

Chen Yuan sighed lightly, stopped the movement in his hand, and the Nine Heavens Xuanhuo suddenly retracted and disappeared in an instant.

Then he tried several more times, and his mind was already sure.

"No wonder, I said how this formation can be preserved and how to play well, it turns out that there is indeed the existence of the best spirit grass in it. ”

"It seems that it should be a fire-type spirit grass, but I don't know if it's the best or the best. ”

Chen Yuan's eyes showed ecstasy.

If it was an ordinary spirit grass, Chen Yuan would not have such an affectionate change.

After all, he had already pocketed the Black Feather Grass, and with the spirit stones in this place, it was enough for him to break through.

But the changes that occurred in the process of breaking the formation just now raised a sense of expectation in his heart.

If it was an ordinary spirit grass, it was absolutely impossible to produce such a terrifying power.

Although the Aggregate Array has the ability to attack, it does not have the effect of Xuanhuo.

And in the process of breaking the formation, the Xuan Huo that could make the void be incinerated could only be so powerful as the best fire-based spirit grass or the heaven-grade spirit grass.

You must know that even the best fire-type spirit grass is an extremely precious existence in the Immortal Cultivation Continent.

Even those top-level great religions don't necessarily have them.

The spirit grass with attack effect of the five systems of gold, wood, water, fire and earth can be said to be one of the most precious spirit grasses.

Just like the Nine Yang Fruit, although it is also a fire-type spirit grass, it does not have the ability to attack independently.

Although it is precious and is also a top-grade spirit grass, it is much inferior to the fire-type spirit grass that can attack independently.

If you want to be seriously graded, the two are not the same level at all.

This kind of spiritual grass that can independently exude its power, although it is called spiritual grass, but judging from the attributes and power of the connotation alone, it is almost a real fairy grass.

But the real immortal grass, even the Apocalypse Continent where Chen Yuan was located in his previous life, had not appeared for hundreds of thousands of years.

Therefore, Chen Yuan guessed in his heart that what Xuanyu Zhenjun had in his hands was likely to be the best fire-based spirit grass, or the heavenly fire-type spirit grass.

Spirit grass grade, lower grade, middle grade, upper grade, best grade, heavenly grade, and finally immortal product.

"If this is really the best fire-type spirit grass, then you won't even need these spirit stones to break through the condensation period. ”

"If it's a heavenly product, maybe there's a chance to complete the Dao body!"

Thinking of this, Chen Yuan's eyes were filled with joy, and he was ready to start breaking the formation!

During the condensation period, the prestige of the earth immortal is achieved, and the innate Dao body is condensed.

This is the first step to get rid of the mortal womb, and it is also the first step to officially enter the immortal cultivator.
