The seven ghost ships stopped in the void, they seemed to have come to a huge karst cave again, and they couldn't see the top when they looked up, the diameter of the karst cave was slightly estimated to be more than a thousand meters, and below the karst cave were those weak water with extremely heavy yin qi.

The weak water flowed slowly under the entire cave, many corpses were floating in the weak water, and there were still some resentful spirits wandering under the water, as if desperately trying to break free from the weak water, but the weak water was like a membrane, and the film was propped up and protruded by the resentful spirits, revealing a hideous and painful face, and then quickly sank again.

And these weak water is not quietly drifting with the current, they sometimes turn into a series of winding and circling water columns, like arms dangling in the air, criss-crossing, when the two curved water columns collide with each other, they will directly turn into a splash of water, and fall back into the weak pool at the bottom of the cave.

And Mu Yu also realized that the seven ghost ships were not suspended in the air, but were grabbed by the huge ghost hands formed by weak water, and they were firmly held in mid-air.

There are countless miserable ghost fires floating in the air of the cave, these ghost fires are green and red, and if you look closely, every bit of ghost fire seems to imprison a soul, constantly struggling, trying to break free from the ghost fire, and it is these ghost fires that illuminate the entire cave.

In the middle of the weak water is a bone tower made of thousands of bones, this tower has eighteen floors, each of which is at least 500 meters in diameter. The body of the tower is piled up with countless human bones, but there are cracks of different sizes, these cracks are as big as ordinary windows, and the small ones are also the thickness of arms, through these cracks, you can clearly see that there are countless souls inside.

These souls are very strange, the souls of each layer are different, and the souls that are imprisoned are not just humans. Mu Yu glanced at the past from a distance, and he saw that the souls in each layer were human races, the souls of demon beasts, the souls of Yumeng demons, and even some things that only had a shadow appearance, without a body.

The souls of each layer seemed to be suffering cruel torture, the black fire was scorching, the knives were slashing and axes, and some souls were pierced through their limbs by black chains, pulling and tearing apart!

These souls were suffering from severe torture, and the screams filled the entire cavern, and the slapping on the eardrums was like a fingernail scraping a porcelain bowl, and it was unbearable.

After each soul is torn or shredded, a strange soul will come next to it, holding a large scoop in his hand, pouring black weak water on the broken soul, and then those souls will slowly begin to recover!

Then Mu Yu's pupils shrank, because these guys who took a big scoop and watered the tormented souls with weak water turned out to be flesh-winged horned monsters!

"Why are there meat-winged horned monsters here?"

Mu Yu had an uneasy premonition in his heart, the Ghost Gate people had always had an unclear relationship with the Flesh Winged Horn Monster, whether it was the Akatsuki who had met in the Mass Burial Valley of the Moyun Mountain Range or the Demon Sect people in the Demon Island who wanted to bring out all the Moon Clans imprisoned in the Demon Town Tower with strange Moon God Stones, all kinds of signs showed that the Ghost Gate people seemed to be brewing some conspiracy.

But fortunately, what Mu Yu saw was that everything in the bone tower was a soul, whether it was a flesh-winged horn monster or other races, or even those things like shadows, they were all soul bodies.

"What the hell are the ghost men doing? Mu Yu was very shocked in his heart, this eighteen-story bone tower must be the eighteen-layer hell that Ghost Buyu just said to be guarded.

There were also countless bones floating around the bone tower, and these bones floated in the air to form bridges, exactly the same as the structure on the ghost pit.

These bridges, which can only be walked by one person, are very narrow and lead to different places, some lead directly to the cliff wall of the cave, some lead to the weak water below, and some bone bridges lead to the entrance to each level of the bone tower.

The complex bone bridges are intertwined in the air, like a huge labyrinth, and if you don't look at it from above, you can't even know which bone bridge leads to where.

At this point, some bones floated over and automatically formed a bridge on the side of the ship. Ghost Buyu and the others had already stepped off the boat one after another, stepped on the bridge cautiously, and quickly walked along the bridge.

Mu Yu stayed at the back, and as soon as he stepped on the bone bridges, he found that there was a strange force on these bone bridges, resisting the pull of the weak water. Obviously, you can't fly at will in this place, and once you fly, you will be dragged down by the strong pulling force of the weak water.

He didn't act rashly, he could only follow these remnants of the ghost sect led by Ghost Buyu to walk along the bone bridge to the center. Halfway through them, the bone bridge in the air began to change, gradually encircling everyone in the middle.

Many of the ghost gate people looked a little uneasy on their faces, this place also seems to be a forbidden place for the ghost gate, ordinary ghost gate people are not qualified to come here, for many ghost gate people, this is the first time they have seen this kind of scene.

But the highest cultivator was obviously familiar with this place, and he walked towards the front with ease, and when he was halfway there, he shouted, "Stop!"

At this time, everyone had already walked for half an hour, and there was still half a distance from the eighteen-story bone tower, but the bone bridge in front did not continue to extend to the eighteen-story bone bridge. The ghost silently took a few steps forward, then respectfully knelt down on the bone bridge, kowtowed in the direction of the eighteen-story bone tower, and said respectfully: "Disciple participates in the ghost ancestor." ”

"The disciple participates in the Ghost Ancestor. ”

All the ghost men who followed behind the ghost were also kneeling on the bone bridge, and they passed in a row, which was very spectacular.

Mu Yu was still invisible, looking around, very wary in his heart, because he vaguely felt that there seemed to be a very powerful figure in this place, and his cultivation was unfathomable, so that he was seriously threatened.

"Isn't there really an old devil in the Mahayana period among the ghost gates?"

Mu Yu was a little cautious in his heart, the sect of the Ghost Sect was quite weird, and in terms of real strength, it was naturally stronger than the Heavenly Star Sect. It wasn't that difficult for Mu Yu to destroy the Heavenly Star Gate, but the Ghost Gate's spells had always been very weird, much more difficult to kill than the Heavenly Star Gate, and he didn't expect that there was such a strange thing hidden under the Ghost Gate.

After these ghost sect people knelt down and saluted, all the souls trapped in the eighteen-story bone tower suddenly screamed in unison, this time it was no longer a chaotic scream, but a regular call. The syllables fluttered high and low, as if they were adjusting their intonation, and then at some point all the ghostly cries seemed to overlap, making a high-pitched and poignant sound.

"What's bothering me?"

The sound spread through everyone's ears, causing people to suffer a strong impact on their eardrums again, and some ghost sect people who were not good at cultivating even turned pale after hearing this sound, and blood oozed from their ears.

The ghost said respectfully and eagerly: "Back to the Ghost Ancestor, someone broke into the Ghost Gate and started to kill, and now the people guarding the Ghost Gate are dead, and only more than 100 of us are left! ”

"Hmph, what about the ghost and the cold man, why doesn't he guard the ghost gate?"

The voice of the resentful spirit reverberated throughout the cave again, and it was a very low and evil voice, and every tone of the voice was quite terrifying, containing a breathtaking power.

At this moment, there was a ghost sect person who had only cultivated to the Jindan stage and couldn't bear the impact of this sound, and screamed miserably, his ears had already burst out of a cloud of blood mist, and his eardrums were actually burst by the voice of the ghost ancestor.

Then the head of the ghost gate of this Jindan period was planted, and the whole person fell under the bone bridge.

Crash!

This unfortunate ghost man fell into the weak water and could no longer make a sound.

The other ghost sect people were horrified, they were also struggling to support the tone of the ghost ancestor, listening to the voice of the ghost ancestor was like a disaster for them, and the low cultivation level couldn't bear it at all.

"Waste shouldn't come to this place!"

The Ghost Ancestor snorted coldly again, and then another Jindan Ghost Gate person's eardrum burst open and fell into the weak water. The Ghost Ancestor didn't seem to care at all about these two Ghost Sect disciples who fell into the weak water, in his eyes, the lives of the Ghost Sect people were no different from other cultivators, if they died, they would die, and they could still become part of the guardian of the weak water.

All the ghost men hurriedly covered their ears and protected their eardrums with spiritual power, seeing that the two companions died unexpectedly, but no one dared to complain loudly, for fear of accidentally becoming the third person who fell into weak water.

Ghost Bu was also quite frightened, this kind of voice was still bearable for him, but the people behind him were all lower in cultivation than him, and they couldn't fly in this place, so he couldn't do anything about the two dead ghost sect people.

"Qi Qi Ghost Ancestor, Lord of the Gate, he went to hunt down a person who was said to be Mu Yu, and he has not returned yet, and the other elders of the Tribulation Period have also left the Ghost Gate, acting on the orders of the Sanzhong Palace, and there is a master of the Tribulation Period of the Gate of Life and Death who took advantage of the situation to enter, and we can't stop it at all. The ghost was silent and quickly told the situation.

"A bunch of waste, even a person in the Tribulation Period can't stop it, what's the use of keeping you?"

The poignant and sour voice sounded again, and all the people of the Ghost Gate lowered their heads and trembled, not daring to refute their voices, and now the masters of the Ghost Gate people's Tribulation Period are not there, where can they resist.

"What about your twins?" the Ghost Ancestor said again, the Ghost Gate people had two souls on their bodies, and at this time, all the Ghost Gate people were left with their own souls, and they were soon known.

The ghost was silent and immediately said: "Back to the ghost ancestor, our twins have had an accident, I don't understand why, the twins in everyone's body suddenly woke up, and the subordinates doubted it...... It is suspected that there is a problem on the other side of the sea of twin corpses. ”

"Can there be problems in the sea of twin corpses?

The furious aura swept out, and the terrible sound waves echoed around again, and then two more of the kneeling ghost sect people couldn't stand the destruction of the ghost ancestor's voice and fell into the weak water.

"Please forgive the Ghost Ancestor. The ghost was silent and hurriedly kowtowed and begged for mercy, and his voice was already panicked to the extreme.
