The invisible flame did not stay in one place. The more than 20 talisman paper cranes controlled by Chen Luo were all burned after a moment, and the discovered "safe area" disappeared, which meant that the invisible flame was moving.

'Heart fire.'

An idea popped up in an unknown brain in the external brain. The benefits of having more brains became apparent. After this round of upgrades in the Qionghua Sect, the quality of Chen Luo's external brain was several times higher than before, and there were many hidden senior masters in it.

"Heart fire?"

Chen Luo’s mind automatically recalled the corresponding content. He didn’t know which brain had seen it, and it was just passed on to him now.

The so-called heart fire is the flame derived from the human heart. This "flame" that originally existed only in emotions was refined by people using great magical powers and summarized into a method. Later, it was used by people and spread to the lower world.

Like the actor's Ai Si Jue, the heart fire represents "anger".

This was the third state of mind-related technique that Chen Luo had come into contact with. The first was Guo Shanxian's Desire, which could arouse people's desires and cultivate through desires. The second was the Actor's Sorrow Technique, which could arouse people's sorrow. If practiced to the extreme, it could induce enemies to commit suicide, without staining their hands with dust.

The third one is the fire of heart that I encounter now.

Those who are touched by the Heart Fire will be extremely angry, and this anger will be absorbed by the Heart Fire practitioners and then transformed into the food they need for practice. These three exercises are not orthodox exercises. But it is undeniable that each one has extremely powerful potential.

After understanding the danger of heart fire, Chen Luo stood up.

Prepare to go down in person.

The enemy has already come to the door, so it is impossible to retreat and wait for others to plot against us. That would be too passive. The danger below has been discovered, so it is a good opportunity to strike first. There must be traces left behind by the inn in this place. With the external brain that Chen Luo currently has, as long as he catches a trace, he can find Ning Chenye's real whereabouts.

He still remembered the favor he received the last time he chased him to the sea.

A layer of light blue light appeared around his body, and Chen Luo stepped on the trees and slowly flew down.

After passing through the poisonous miasma, Chen Luo felt his eyes brighten.

The scene he saw with the paper crane was different. After entering here, Chen Luo clearly felt something was wrong. It was not the surrounding scenery, but the dust floating in the air. He had not noticed these inconspicuous dust when he saw them with the paper crane, but when he came down in person, he quickly noticed the problem.

These floating particles are not dust, but poisonous insects!

All these poisonous insects are controlled by a stronger poisonous insect and can be considered as offspring, just like fungus strains.

"Brother Han Jiu's Spring and Autumn Gu."

Chen Luo sensed a familiar aura from these particles. This made him alert, and the four poisonous insects that had just evolved in his body flew out on their own and began to devour the gray-white particles that were close to him.

The four insects transformed by the Immortal Emperor Changqing immediately took effect.

Especially the Soul-Bonding Gu and Life-Borrowing Gu, these two insects rank high on the list of strange insects, although they are not as good as the Spring and Autumn Gu, they are not much worse. The combination of the two can easily resist even the breath of the Spring and Autumn Gu.

Chen Luo walked along the mountain road for a while and slowly approached the area where the heart fire was located.

The spiritual consciousness dispersed.

Just like before, it was completely undetectable and invisible to the eyes. This was the uniqueness of the Heart Fire. Not only Chen Luo couldn't see it, but other people couldn't see it either. Because the 'Heart Fire' was not a real flame.

'Left front.'

The ghost cultivator Xue Ning's brain suddenly emerged.

The next moment, Chen Luo's vision changed. The valley turned grayish white, and three huge grayish white flames floated in the front left position like ghost fires, constantly moving.

This is the perspective of a ghost cultivator!

Chen Luo's idea from a long time ago finally came into play at this point.

"Can ghost cultivators see the heart fire?"

Chen Luo immediately thought of the demon cultivator's brain, so he moved his mind and called up the brains of the Black Horn King and the dragon. Different perception frequencies emerged in him.

The dust particles floating in the air are no longer inconspicuous dust, but you can clearly see the teeth of these particles, densely packed, yet extremely clear. This is an unprecedented weird perspective, but when Chen Luo saw it, he felt it was extremely reasonable.

After invoking the Demon Bone Array Pattern Technique, the bone patterns on Chen Luo's body lit up and demonic energy began to emit.

As expected, those tiny poisonous insects stopped coming closer after sensing the evil spirit. The four strange insects lying on his shoulders also slowly relaxed and began to be alert to possible enemies in other directions.

After solving the problems of the poisonous insect and heart fire, Chen Luo continued to move forward.

After passing the heart fire area, Chen Luo took out a handful of talisman paper again and summoned a large number of talisman paper cranes in the same way, asking them to help him explore the way.

The journey was slow but safe.

The Talisman Crane helped Chen Luo explore several dangerous areas. After passing the Heart Fire area, the area behind was "water". This water, like the Heart Fire, carried a certain emotional power and was not real water. Chen Luo's demon cultivation perspective was just right for him to see this water.

Stop along the way.

Half a day later, Chen Luo finally saw something different.

The land in front of us was no longer grayish white, but a normal yellow-brown color. The land area was about three kilometers in diameter, and there was a single tree growing in the middle. The trunk of the tree was straight, as if it had been pruned by someone, and there was no branch on it.

Above is a huge tree crown, shaped like an umbrella.

After Chen Luo's talisman paper cranes approached the tree, they all lost control and fell onto the branches of the tree canopy like flying insects. Although they were not damaged, they lost contact.

"Tree?"

Chen Luo didn't know why the inn came here, but that thing obviously had its own consciousness. Ning Chenye and the others were just guests in the inn.

He took out a Yin Lei ball from his storage bag.

This tree is not normal at first glance. It is definitely impossible to go over and test it in person! The best way is to blow it up directly. There are so many Yin Lei balls in the storage bag, just in time to test the water with this tree.

Just as Chen Luo was about to take action, a black shadow suddenly flashed by.

boom!!

Without thinking, Chen Luo raised his hand and threw the Yin Thunder Ball in his hand. The Thunder Ball exploded in the air, turning into a circular arc ripple, and the plasma light illuminated the entire area.

The bone patterns on Chen Luo's body became brighter, and his figure disappeared from the spot.

Chen Luo's second bone pattern effect is "thunder". In places where there is thunder, the power he bursts out is even stronger.

In a flash of lightning, a black chessboard appeared in Chen Luo's hand.

The afterimage flashed by, and the right hand holding the chessboard slapped the black shadow on the back.

BANG!!

A muffled sound.

The chessboard and the black shadow collided with each other, but the expected scene of the head exploding did not appear. This black shadow was like liquid, and the chessboard hit its body as if it fell into water. A lot of force was unloaded by the fluid, and a layer of inky black ripples appeared in the area right in the middle of the chessboard.

The black shadow took advantage of the situation and turned around, wrapping its body around Chen Luo's arm like a poisonous snake and biting towards his throat.

Sharp teeth like a wild beast.

Chen Luo did not retreat a single step. His bone patterns lit up. He raised his left hand and punched the black shadow rushing towards him in the face.

boom!!

The two forces exploded, and the gray-white poisonous insects were scattered all around. Large pieces of gravel flew up, and the leaves of the big tree in the distance kept shaking under the aftermath of the two people's fight, making a rustling sound. The talisman paper crane that had previously rested on the branch was swept away by the airflow and flew away like a flying insect.

Chen Luo stood in place, his spiritual awareness becoming active.

The shadow disappeared.

But it did not escape his perception. Chen Luo, who possessed the multiple perception abilities of demon cultivators, ghost cultivators and humans, caught his trace.

After a moment, Chen Luo's figure, which had been standing still, shook again, and the afterimage remained.

The solid body gradually faded and finally disappeared.

BANG!!

It was still the chessboard. This time, Chen Luo seemed to have predicted the position of the black shadow. At the position where the opponent was about to appear, he swung the chessboard and smashed it down from top to bottom.

“Awesome.”

The black shadow still used the same method to resolve the attack, but this time it was obviously not as easy as the last time. A strange sound came out of his throat. His body was slapped to the ground by Chen Luo like mud, and was covered with a circle of yellow-brown mud.

The next moment, the yellow-brown soil became strangely active. They rolled up and gathered like carnivorous plants. The tree roots buried under the yellow-brown soil coiled towards the black shadow like poisonous snakes.

"Elder Lu Ying will avenge me."

The shadow uttered a word, but the tree obviously didn't want to listen to his nonsense. It rolled the shadow in at the fastest speed, and countless teeth emerged from the densely packed roots. These teeth gnawed at the shadow like crazy, and no matter how hard he tried, he couldn't avoid it.

After struggling for a while, this strange black shadow was eaten up by the tree.

After eating the black shadow, the tree roots returned to the ground, were covered with yellow-brown soil, and returned to its previous shape of a big tree.

Chen Luo stood by and did not interfere with the big tree's eating.

He stared at the big tree in front of him for a moment, and then suddenly asked a question.

"Brother Ning?"

The tree stood still and did not respond to Chen Luo's words. But Chen Luo clearly felt the fluctuations. He sensed Ning Chenye's aura from the tree.

In the Tiannan Region, many people know that in order to break through the Divine Transformation Realm, the Yin-Yang Demon Lord fused with the remains of a demon beast from the upper realm.

But no one knows what this monster is.

Chen Luo had previously thought that it was a strange beast like the Lingchi monster, but when he saw the tree, he instantly understood what kind of monster Ning Chenye had swallowed.

It's a tree demon!

The so-called demon beast was just a rumor spread by Yin Yang Demon Lord himself. As a casual cultivator, Yin Yang Demon Lord did not trust anyone.

"With our brotherly friendship, I would be able to recognize you even if you turned into ashes, let alone a tree." (End of this chapter)
