The underworld here is really not simple.

Looking at the thorny vines that were retracting into the grass on the opposite side, Chen Fan shook his head slightly, suddenly turned around, and walked towards the lava lake with his back to the vast forest.

Chen Fan was not discouraged, but became more cautious.

This lava lake covers an extremely large area, probably tens of kilometers in circumference, and the distance between the small hills and the lava lake is about hundreds of meters, and the closer you get to it, the more you feel a burning heat.

You can't fall into the lake...... Chen Fan decisively confirmed this matter, with his current physique, he was far from being able to withstand the damage of magma.

Chen Fan can bear these hot gases, after all, the physique of 21 points is not covered, and ghost fire wings suddenly appeared behind him, flying high.

The height of the Ghost Fire Sparrow's wings is related to its physique, and now Chen Fan flies to a height of more than 100 meters with complete ease, relying on the agility and spirit of the Three Realms, the speed of the wings is also beyond the fastest Eagle Falcon.

Chen Fan cautiously approached the sky above the lava lake, and this time nothing strange came out. But there were always bubbles bubbling in the lava lake, like something was rolling in the water.

As Chen Fan flew above the lava lake, in the unique perspective of the Soul Suppression System, he suddenly discovered many bright light clusters in the depths of the magma lake.

There are undead down there!

Pity...... The undead in the depths of the magma, Chen Fan couldn't get close.

Chen Fan narrowed his eyes slightly, keeping himself at a maximum height, not planning to get close to the surface of the magma lake.

For now, it seemed that all he could explore was the towering castle in the middle of the magma lake.

Chen Fan flew towards it at high speed, and the distance of dozens of miles seemed far away, but it took less than an hour to fly at high speed, which was the reason why Chen Fan did not fly with all his strength in order to save his physical strength.

From the unique perspective of the Soul Suppression System, Chen Fan discovered countless light clusters hidden in the magma lake along the way, as if there was another world under the magma.

Perhaps, when his strength increases to a certain level, he will be able to go to the world under the magma lake to explore.

I don't know if he will be able to come here again in the future, Chen Fan tried to communicate with the soul suppression system on this point.

"For 200 soul power, you can choose the dungeon plane that has already descended in the monthly dungeon option, and the place of descent is located in the underworld."

The golden text in the attribute bar flashed away, causing the corners of Chen Fan's mouth to curl slightly, but he quickly suppressed these superfluous thoughts.

Leave it alone for the time being, do what you can do in front of you, and explore as much as you can.

The castle is already close at hand, and it looks very majestic.

The black walls of the ancient castle didn't know how thick they were, but they actually blocked the detection of the soul suppression system, so that Chen Fan couldn't estimate the situation in advance.

The foundation stone beneath the castle is deep into the magma, and the exposed part forms a staircase hundreds of meters long that leads to the gate of the castle.

Chen Fan circled around the ancient castle and found that it covered an area of at least a mile, but the black walls were integrated, and there were no windows.

The current Ghost Fire Sparrow Wing could not support the exploration beyond a height of hundreds of meters, so Chen Fan finally chose to fly towards the gate of the ancient castle.

However, just as he was about to fly directly to the gate of the ancient castle, an invisible force suddenly blocked in front of him, making it impossible for him to approach.

Well?

Chen Fan frowned slightly, and tried with all his strength, but he still couldn't get close, he thought for a while and suddenly fell towards the steps leading to the gate of the ancient castle.

And just as he landed, this invisible force disappeared in an instant.

Can you just walk through?

Chen Fan exhaled deeply, the ghost fire finch wings behind him disappeared, and his left arm turned into an ancient python, and he gently tentatively landed on the steps.

The moment his toes landed on the steps, the entire lava lake shook suddenly, and countless blood-colored butterflies flew out of the lava lake in an instant.

These blood-colored butterflies are delicate, like virtual lights and shadows in the painting, waving their wings that emit blood, and fluttering around the castle in the lava lake.

Chen Fan suddenly grasped the black sword, but these blood-colored butterflies did not approach the ancient castle.

From the unique perspective of the Soul Suppression System, they exude a faint glow, which is obviously condensed by the power of the undead.

Chen Fan's eyes lit up slightly, and without the slightest hesitation, he suddenly jumped into the sky, and the ancient python waved, but the ancient python pounced on the blood-colored butterfly as if it hadn't touched anything, and went straight through their bodies.

Oh?

Chen Fan didn't stop moving, and suddenly personally punched the many blood-colored butterflies closest to him.

Soul Suppression System Attraction Activated!

With a bang, many blood-colored butterflies shattered under this punch, turning into countless points of light and suddenly pouring into Chen Fan's body.

+1 Soul Power!

+1 Soul Power!

+1 Soul Power!

……

At least dozens of points of soul power poured into his body all of a sudden, making Chen Fan couldn't help but gasp slightly.

Are these blood-colored butterflies really all incarnated by the undead?

And it is still an undead who can bring him soul power, and ordinary undead who are too weak are not even qualified to contribute soul power to him.

But now is not the time to think, Chen Fan's eyes were glowing green, the ancient python on his left arm suddenly disappeared, and the ghost fire wings reappeared behind him.

Like a tiger entering a flock of sheep, Chen Fan rushed into countless blood-colored butterflies.

But at this moment, the gate of the castle, which has existed for an unknown amount of time, slowly opened!

The unusually ancient aura poured out of the castle gates like a whirlwind, bringing everything around it to a standstill.

At this moment, Chen Fan suddenly realized that his body was strangely unable to move, only his mind was still turning.

An ancient-sounding voice rang out from the top of the castle, which I didn't know how high.

This voice was in a very complicated-sounding spoken language, but it was directly transformed into a meaning that he could understand in Chen Fan's mind.

"Finally someone is here...... Do you crave my power, the myriad planes I discover? I can give it all to you if you want! I've put everything in the castle, the young generation of the abyss who have been chosen by the Scarlet Butterfly, come on! Compete for the legacy of my Gore Demon King! ”

Although the sound was not very loud, it carried a vibration wave like a storm, and it kept spreading into the distance, over the lava lake, and over the strange forest of unknown size.

It was as if the sound was going to spread all over the world!

And, with this sound, countless blood-colored butterflies suddenly began to fly rapidly in all directions.

Chen Fan's body also returned to normal at this moment, and he attacked the butterfly that was flying away without any hesitation, and there was only one thought left in his mind.

MMP, it doesn't matter if you're a Gore Demon King or a One Piece, give me back these flying soul powers!
