"Boom ......"

The diamond-shaped spar was releasing bursts of mana outward, erupting with a roar eight hundred meters underground.

Fang Yu hadn't really touched the diamond-shaped spar yet, but when he got closer, he could feel the terrifying mana surging.

It's hard to imagine a hedron used to sustain such a huge and powerful circle...... After tens of thousands of years of attrition, it can still contain such a large amount of mana.

"When this spar was the earliest, how much magic energy should it contain? Fang Yu slowed down and came to the suspended hedron stone.

He looked at the hedron in front of him.

The hedron was spreading its magic energy, bursting out with bursts of powerful coercion.

Ordinary people standing in this position will be directly crushed into meat sauce by this coercion.

But to Fang Yu, this coercion was as if it didn't exist.

He didn't hesitate for long, and decisively stretched out his right hand to the hedron.

"Boom!"

The moment Fang Yu's right hand touched the hedron, the hedron immediately erupted with extremely terrifying power.

The surrounding rocks were blown apart, and smoke and dust were everywhere.

But Fang Yu didn't let go, and his right palm had already grasped the spar.

At this time, Fang Yu was able to perceive the surging mana energy inside the spar more clearly.

"These magic abilities are a bit peculiar, but don't care, they can be absorbed directly. Fang Yu's eyes moved slightly, and he ran the Spirit Devouring Technique.

"Poof!"

A swirl of red light appeared in Fang Yu's palm.

The mana energy inside the spar poured into Fang Yu's body like a torrent.

"Whoosh......"

In the process, the hedron vibrates violently and the heat bursts out.

Every second of the mana released by this hedron is enough to shatter a mountain.

However, Fang Yu absorbed all these magic energies into his body.

"It is worthy of being a spar made by several powerhouses of the Ascending Immortal Realm, and the magic energy in it is really like the vast and boundless sea water...... "Fang Yu's eyes flashed with surprise, and he said in his heart, "It's just that these magic abilities are really not right, they are not particularly pure, and they are also a little impurity, it feels like a ......"

After continuing to absorb it for a while, Fang Yu recalled the magic circle that had been restored by the Eye of the Great Dao before, and immediately understood.

Not all of the magic energy inside this spar was left by a few saints back then!

No matter how much mana energy there is, after years of consumption...... It is impossible to keep it so abundant.

The reason why it is so abundant...... It is because this spar not only consumes mana energy to maintain the huge magic circle above, but also draws mana from the magic circle, so as to obtain the mana energy that continues to maintain the magic circle.

And where does the magic of the circle come from? It comes from the demons in the jungle.

It's a circle that loops autonomously.

Use the magic energy of those demon spirits to trap the demon spirits, and during this period, they continue to weaken the strength of those demon spirits.

Such a magic circle can be described as superb.

The saint who set up the circle at the beginning was indeed very powerful.

Fang Yu thought as he absorbed the magic energy inside the spar.

Gradually, the mana energy in the hedron became less and less, until it was absorbed by Fang Yu.

The diamond-shaped hedron no longer glowed, and became an empty shell.

Fang Yu put away the empty shell of this spar.

Bring it back to the Feather Gate and use it as the core of the circle in the future.

After doing all this, Fang Yu was ready to return to the ground.

"Bang, bang, bang......"

However, there was a rhythmic roar on the ground.

The spar had already been absorbed by Fang Yu, so it was naturally impossible to cause such a vibration again.

Fang Yu immediately raised his head and rushed towards the ground.

"Hiss......"

"Roar!"

At this time, those demon spirits on the ground also seemed to be out of control, and let out bursts of roars.

What happened?

Fang Yu squinted his eyes and rushed back to the ground at an extremely fast speed.

"Whew!"

Fang Yu's figure rushed out of the ground and stood in the air.

At this time, he saw that directly in front of him, on the clearing, there was a giant creature!

This creature looks like a python, but when you look closely, it looks like a centipede!

Its body was divided into more than a hundred segments, each with an extremely ugly face, red eyes, white fangs, and claws of different shapes growing on both sides.

In addition, the color of the scales in each section is different, and from top to bottom, no two sections are exactly the same color.

The creature's height was close to three hundred meters, and its head was already higher than the average height of the jungle.

Its aura is extremely powerful, and the expression of each section of the face is different, as if it exists completely independently.

"Roaring ......"

The more than three hundred demon spirits behind Fang Yu were all staring at the creature in front of them with extremely vigilant eyes at this moment, and the aura on their bodies was gradually released.

"What kind of demon spirit is this?" Fang Yu asked with a frown.

"It'...... It was originally the king of centipedes. At this time, the Bone Snake Venerable who had dealt with Fang Yu spoke.

"And now?" Fang Yu asked as he looked at the Bone Snake Venerable.

"It gives birth to demonic nature...... It no longer belongs to the Spirit. Bone Serpent said in a hoarse and deep voice.

"Demonic ...... Is this a demon?" Fang Yu sensed it, his eyes changed slightly.

Another adversary!

If it's a demon spirit, there's no reason not to be afraid of him.

But this centipede demon was now completely hostile, and every section of his face was roaring at Fang Yu, extremely fierce.

"It seems that after the magic circle was lifted, the pressure originally exerted on it disappeared, causing its long-accumulated demonic nature to explode, and it became a demon in an instant......" Fang Yu's eyes flickered, and he said in his heart.

Demonic ...... Where did it come from?

Is it possible that just feeling hatred and repression can give birth to demonic nature?

I don't think so.

In the past, the perception of going crazy refers to the fact that there is a mistake in the cultivation process, or the mentality is too anxious, which causes the cultivation to deviate and hurt oneself.

Such an understanding cannot explain the demonization of this plane today.

"That's right...... Those black and red breaths. ”

Fang Yu suddenly remembered the black-red aura that flew out of Duan Ao's body after he died.

Those breaths are probably the key to entering the demon!

"Chaos Fire Demon, is it also because of those black and red aura, it's not ......like what Lihuo Jade said," Fang Yu's eyes moved slightly, and he thought to himself, "It's a pity that I didn't pay attention to ...... at that time"

"How do you feel like you've been encountering demons lately?"

"Click......"

While Fang Yu was still thinking, the faces on the hundredped insect demon in front of him made a harsh and unpleasant sound.

Its outer limbs are moving, which makes it uncomfortable to look at, even creepy.

Xu Jialu in the distance was far enough away from this centipede demon, but he was still covered in goosebumps and his face was pale.

"The appearance of these demons is really uglier than the other. Fang Yu frowned and said.

"Hiss......"

Before Fang Yu and the more than three hundred demon spirits behind him moved, the hundred-legged insect demon in front of them suddenly moved!

Every outer limb on its body danced.

"Woo Woo ......"

A piercing whistling sound rang out in the air.

Countless extremely sharp blade qi rushed towards Fang Yu and the group of demon spirits behind him.

"Whoosh......"

Fang Yu's figure flickered, easily dodging these fierce aura.
