In fact, on the premise of not mastering the power of the Great Dao, even if you use special methods such as "Condensation Decision" to condense the heart world in advance, the heart world will be quite fragile.

After all, the world of the mind is structured according to one's own comprehension of the Tao.

However, Chen Fan mastered the five paths, but to a certain extent, it increased the stability of the mental world.

Earth, fire, water, and wind, as the four elements, are also the foundation of the world, but they are quite suitable for building a world of mind.

It took Chen Fan about half a year to exhaust the power of the heart in the thunder ghost golden pill, and finally succeeded in condensing his own heart world.

Although there are still differences with the true Immortal Quadruple Mind World, you must know that Chen Fan has only been promoted to the Immortal Quadruple for a few years so far, and he has the highest comprehension of the Dao Sword Dao, and there is still a distance from the Great Dao.

After mastering the world of mind, he naturally has a certain degree of grasp and understanding of "spatial change".

"If I had condensed this world of mind at the beginning of the Mei Meeting, I would not have lost to the fish and tiger......"

His expression was subtle.

If others forcibly introduce him into the psychic world, he can use his own psychic world to counteract!

And after mastering the Psychic World, he can also directly use the power of the Psychic World to lock the surrounding space, so that the people around him cannot urge things like the Trace Talisman.

This reminded Chen Fan of the original Blood God Sect Leader Sang Ning.

"Sang Ning is probably also a master of the world of psychic physiognomy...... Is it that he has already reached the fourfold of immortality, or has he comprehended the world of heart in advance like the Sword Emperor of the Sword Sect? ”

At that time, Chen Fan only knew that Sang Ning himself was more than Immortal Triple Equal, and he only knew that his person's strength was so strong that he couldn't resist it at that time, and Chen Fan couldn't be completely sure whether his person was Immortal Triple or Immortal Quadruple.

Now that I think about it, it is certain that it is possible that his person is also immortal fourfold.

In fact, not only Sang Ning, but also the heart world locked the space when Chen Fan and Yuhu were dueling in Mei.

At the beginning, when facing the fish tiger, Chen Fan once urged the "Wings of the Sky", and later when he urged again, the distance traveled was extremely small, and it should be the fish tiger who locked the space through the power of the heart world.

After completing the condensation, Chen Fan did not stop, and immediately rushed back to Lei Xiang Mountain.

He asked the clone to wait around with the crystal, and then the deity took the initiative to enter the cave.

With the help of "Hidden Void" and "Void Hidden Sword Technique", he slashed out with a sword against the immortal sixfold thunder ghost.

This thunderous ghost, with a body of hundreds of zhang tall, is like a small mountain, even if Chen Fan shot the "Hongmeng Sword" with all his might, it didn't hurt this big guy much.

On the contrary, it stimulates the ferocity of this monster!

Roar!!

The angry roar of the Thunder Ghost resounded through the sky.

The earth roared continuously, like an earthquake, but the already dense thunder in the sky was even denser, blasting towards Chen Fan himself one by one!

Chen Fan didn't dare to stay at all, and immediately summoned Fluttershy and fled.

The six-fold thunder ghost was really unwilling for Chen Fan to escape, but he took the initiative to pursue him.

It's a pity that she's not as fast as Fluttershy.

Listening to the roar behind him gradually drifting away, Chen Fan suddenly felt a terrifying pulling force coming from the void.

In the past, Chen Fan faced the power of this kind of space, but he had no resistance at all, but now, it is different.

Chen Fan decisively urged the power of his own mental world to resist.

But.

After all, Chen Fan was forcibly condensed in advance in the Psychic World, so although this Immortal Sixfold Thunder Beast was far enough away from Chen Fan, the pull of the Psychic World also made it difficult for Chen Fan to support it.

"If I get closer to him, I'm afraid I will be absorbed into the world of psychic physiognomy in an instant......"

Chen Fan's face also flashed with sharpness.

At this point, it is enough to be able to resist a little.

Without him having to say anything, Fluttershy's speed soared, instantly carrying Chen Fan out of the range of the pulling force and heading off into the distance.

The thunder ghost behind him roared angrily, but he could only slowly follow behind and eat ashes.

And at the same time.

Chen Fan's doppelganger quietly took the square-shaped spar and entered the cave of the thunder ghost.

Chen Fan carries Fluttershy and keeps a certain distance from the Thunder Ghost, but he is not pulled into the heart world by the Thunder Ghost.

When chasing and fleeing.

At the location of the Thunder Ghost Cave, there was a roar that resounded through the heavens and the earth.

A huge pillar of lightning spread and rose, piercing through the sea of fog in the sky and illuminating the surrounding world.

And in this lesson.

In the entire Lei Xiang Mountain, the thunder light that spread and disturbed was even more ten or a hundred times stronger.

The blinding light of the scorching sun gradually died out.

Then a restless, evil terrifying force came from within the lair of the immortal sixfold thunder beast.

At the same time, under Chen Fanxing's divine seal, he also completely lost his sense of the doppelganger.

After the immortal sixfold thunder beast roared in the sky, it no longer pursued Chen Fan, turned his head, and looked at the dazzling thunder light behind him, but it was prostrate on the ground, but its two huge eyes were full of respect.

The next moment, the dazzling thunder light expanded and shot out, like a surging flood, flooding the entire Thunder Xiang Mountain in the blink of an eye.

The surroundings became a sea of thunder and lightning.

……

At the same time, the periphery of Lei Xiang Mountain.

Bo Langfeng held a purple spar in his hand, his eyes burning as he looked at the surging thunder in the sky, and a flash of excitement flashed on his face.

"This Chen Fan is also fast enough, he actually entered the depths of it so quickly......

"But it saved me a lot of trouble......"

He licked his lips and clutched the amethyst in his hand firmly.

The thunder in the sky converged in the blink of an eye on the amethyst in his hand.

Then his body blinked, turning into phantom light and rushing into the thunder light.

……

"What a terrifying power!"

Thunder and lightning attacked, even with Chen Fan's physical fitness, he felt a tingling pain all over his body.

At the same time, black gas lingered in the thunder and lightning, and a special corrosive force surged.

"It's a force!"

Chen Fan's face changed greatly, and he immediately summoned the source bead to protect his whole body at all times, so he felt a lot more stable in his heart.

And suddenly, there was a roar in front of him, and the immortal sixfold thunder ghost suddenly began to rush around and roar, but it was a force that entered the body, and his spirit was affected.

Previously, this power should have been suppressed by some kind of force, or sealed inside Lei Xiang Mountain, but Chen Fan came with a token, but this seal was lifted in an instant.

"I'm afraid the doppelganger is already finished......"

Sensing the power of the terrifying outburst, the corners of Chen Fan's mouth twitched.

Without the protection of the source bead, no matter how strong he is, it is impossible to resist the erosion of this wave of power.

And he is actually far away from the center of the Evil Strength Explosion, but he is still affected so much, and the core position of the Evil Strength Explosion will only have a greater impact.

"Generally, the sixfold immortality will collapse instantly in the core position......"

Chen Fan waited for about half an hour, and the impact of the powerful wave slowly descended, but the surrounding thunder was still restless, forming a huge thunder and lightning barrier around Lei Xiang Mountain.

At this moment, the wave of power has passed, and although the impact of the power has dropped greatly, except for Chen Fan, the thunder ghosts or other creatures in the Thunder Xiang Mountain have all been transformed into demons.

Chen Fan took a deep breath, his eyes narrowed, but his gaze was not far away, and he had completely become a demon with the immortal sixfold thunder ghost.

After hesitating for a moment, he didn't make a move on this guy.

Even if he becomes a demon, the combat power of the Thunder Ghost will not be reduced too much.

This creature is originally a natural fierce beast, unable to transform into shape, and lacks intelligence.

After transforming into a demon, its wisdom has not decreased too much, and it still relies on its body instinct to fight against people, but because of the more power in its body, it is more difficult.

"I don't have enough hard power, but there's no need to fight this guy......"

He shook his head and took the initiative to move towards the source of the power and thunder.
