Chu Yan was surprised, looking at the spiritual bamboo transformed by the spiritual power in mid-air, his eyes flashed.

The transformation of spiritual power not only requires the rich spiritual power of heaven and earth, but also requires some specific conditions, such as the Great Array of Gathering Spirits, Heavenly and Earth Treasures, or Rare Spiritual Treasures!

Chu Yan gathered his mind, closed his eyes, and let the green stars scattered by those spiritual bamboos fall towards him, and for a while, the bamboo house fell into silence.

As soon as Chu Yan's mind entered the sea of knowledge, he felt that in the sea of knowledge, there was a burst of spiritual light, and a few wisps of spiritual light floated in his sea of knowledge, which was exactly the same as the sword intent in the wooden sword he felt in the Lingbao Hall last time.

"It can really improve the ability to perceive!" Chu Yan said secretly.

Immediately, the divine consciousness cautiously leaned towards the few wisps of spiritual light in the sea of consciousness, and with a slight touch, he fell into it.

In an instant, on Chu Yan's side, a sword intent cyclone appeared, and Chu Yan's sword intent Great Perfection Realm continued to improve.

Time flies, and three days have passed in the blink of an eye.

Chu Yan, whose mind was completely immersed in the sword intent comprehension, retracted his breath slightly and slowly opened his eyes.

"Yes, yes, the Great Perfection Realm of Sword Intent is so mysterious and profound, this realization is really beneficial!"

Chu Yan got up, his whole body breath converged, and he pulled out the wooden sword behind his back, but he slowly waved it in the bamboo house.

"True sword... Sharp edge...."

"True sword... Perseverance..."

"True sword... Fearless..."

"True sword... Invincible..."

"True sword... Death...! ”

With each sword, he whispered a word, his voice gradually became louder and louder, his eyes became brighter and brighter, his gaze was sharp, if the electric light was burning, as if the sword light was about to shoot out...

"Sharp... Tenacity... Fearless... Kill! ”

The restrained sword intent to the extreme burst out in an instant, and the whole person seemed to turn into a sharp sword, and the wooden sword swung out, without any momentum, it was like breaking the sky and the waning moon, shining to the extreme, splitting the space.

After a long time, Chu Yan put his sword into the sheath with a faint smile on his face.

But then, Chu Yan's face froze, and he was stunned on the spot.

In the sea of knowledge, the flame martial soul is gone....

Frowning, his divine sense poked out, and he instantly made contact with the missing flame martial spirit.

To Chu Yan's surprise, the Flame Martial Spirit had already rushed out of the bamboo house at this time, reaching the depths of the bamboo sea outside the house, and flew rapidly through the forest at an extremely fast speed.

In the emerald green bamboo sea, countless green dots and starlight flickered, and while the flame martial soul swept by, it absorbed all these green dot starlight, but did not stop, running wildly all the way, as if there was something in front of it that attracted it.

Soon, the Flame Martial Spirit reached the very center of the Bamboo Sea and plunged into the soil without hesitation.

Dozens of meters underground, all of them are green crystals, not ordinary soil at all.

The Flame Martial Spirit passed through these green crystals, all the way down, a hundred meters, two hundred meters, three hundred meters...

The thickness of these green crystal layers was extremely deep, and the Flame Martial Spirit had drilled for five hundred meters, and it was still a green glow, with no end in sight.

At this time, Chu Yan stayed in the room, sensing the situation around the Flame Martial Soul, and was stunned.

These green crystals have the same spiritual power attributes as the bamboo condensed in the room just now, but one is close to a liquid state, and the other is solid, and the quality is very different.

At eight hundred meters, the Flame Martial Spirit finally penetrated the green crystal layer and arrived at a green world.

There is still a sea of bamboo, but the first bamboo is composed of green crystals, and the first bamboo leaves are like green gems.

A large piece of bamboo sea has a height of hundreds of zhang, much higher than the towering ancient trees, each green crystal bamboo has countless green stars lingering, a fairy, poetic and picturesque.

In the middle of this bamboo sea, there is a green lake, all of which are liquid heaven and earth spiritual power, and the spiritual energy is like a tide, floating on the surface of the lake.

This... Is it the underground world of Skyscraper?

In the middle of the lake, there is a very small black soil, and a small green bamboo grows long!

The green bamboo, which is only one meter high, has more than a dozen bamboo branches in clusters, and as the aura of the lake blows, the bamboo leaves shake gently, and a few drops of green spiritual liquid on the young bamboo leaves are dripping into the lake.

Chu Yan was taken aback, could it be that the "Spiritual Qi Transformation" of this Sky Valley was produced by this cluster of young bamboos!?

What kind of bamboo is this!?

The flame martial soul suspended in mid-air suddenly exhaled a strange sound, and the fire body trembled, rushing towards the young bamboo in the center of the lake, constantly winding.

The young bamboo suddenly glowed green and shook gently.

With the shaking of the cluster of young bamboos, on the entire green lake, the spiritual wind suddenly became strong, the lake tide surged, and the waves more than ten zhang high slapped towards the flame martial spirit, but it was completely refined by the flame martial soul spewing out a large ball of flames.

The lake waves composed of these lakes are extremely full of spiritual power, and after the flame martial soul has refined a few waves, not only is the fire body a few times larger, but even Chu Yan, who is thousands of meters away, also feels the true qi in his body growing wildly.

Looking at the appearance of the young bamboo in the center of the lake dripping into the lake, this large area of lake water, I don't know how many years it has been condensed, plus the natural spiritual environment of this underground world, I am afraid that it will take at least a thousand years to form.

After refining more than a dozen waves, the fire body of the flame martial soul doubled in size, and the color became darker and darker, and a trace of purple appeared in the fire body.

Those few traces of purple fire line, in the body of the flame martial spirit, looked extremely extraordinary.

The flame martial spirit still lingered around the young bamboo in the middle of the lake, and after a while, the entire fire body finally wrapped the young bamboo and completely devoured it.

However, to Chu Yan's great surprise, after the young bamboo was wrapped in the Flame Martial Soul, it was not burned to ashes, but still looked green, as if the fire of the Flame Martial Soul could not hurt him at all.

After the Flame Martial Spirit succeeded, he quickly returned from the underground world to the bamboo house where Chu Yan was.

The young bamboo floated above Chu Yan's head, and suddenly, one after another, the green aura that was surging and pure to the limit rolled down from the young bamboo, surging into Chu Yan's body.

Chu Yan's body shook suddenly, as if he had fallen into a pool of water, and the internal organs in his body became crystal clear, and the majestic breath made Chu Yan feel that his soul was going to be out of his body.

Shocked, Chu Yan hurriedly operated the Rakshasa Infinite Determination, slowly fusing all the green spiritual power that poured into his body.

But these green spiritual powers were very different from ordinary heaven and earth spiritual powers, in Chu Yan's body, only part of them were integrated into the true qi, and the rest were all drilled into every inch of flesh and blood in Chu Yan's body, mixed into one.

A trace of black dirty blood flowed out of Chu Yan's body, which was very similar to the situation when he swallowed Xiao Shanguo at the beginning, but the difference was that this time there was more black stained blood.

Soon, the dirty blood on the surface of Chu Yan's body turned into black gelatin.

From a distance, Chu Yan's current appearance was as if he was wearing a black armor.
