At this time, Lei Yu's strength had reached the sixth order of thunder qi, and it was easy to deal with this fish water ghost, and it was very easy to kill it in an instant.

"Let's leave the Lethe River first!" Lei Yu made a decision to leave the Lethe River.

Now he has the thunder of Lethe River, he is like a fish in water in the Lethe River, and he can even control the water of the Lethe River, and it is very easy to leave the Lethe River.

Lei Yu swam towards the river, and the surrounding Lechuan River did not have any obstruction, and it was still constantly lifting Lei Yu and raising Lei Yu to the surface of the river.

"Bang!" Lei Yu finally rose from the bottom of the water, and he could see the surface of the Lethe River. The Lechuan River is still vast, turbid and yellow, and there are endless resentments contained in it. It's just that Lei Yu didn't feel the slightest discomfort, swam in the Lechuan River, and headed towards the shore.

After half a pillar of incense, Lei Yu finally arrived at the bank of the river, and the road of fire extended into the unknown distance, red and bright like fire, as if covered with a carpet of flames, it was the only scenery on the Lechuan River.

"Could it be that this Lethe River is really going to flow to the Sea of Nine Shadows?" Lei Yu changed his clothes and stood on the bank of the river, watching the rolling Lechuan River flow forward, but there was a little thought in his heart.

The Sea of the Nine Shadows is the final destination of the legendary Hell Styx, whether it is the Lethe River or other Styx, without exception, they will all converge into the Sea of the Nine Shadows, which can be described as extremely vast. Moreover, there are quite a lot of resentments and evil things contained in the Sea of Nine Shadows, which are very terrifying.

Lei Yu's eyes looked intently at the rolling Lichuan water, and he kept thinking in his heart. After this trip to the underworld, the doubts in his heart not only did not decrease, but also continued to increase.

The Lechuan River and the flowers on the other side have appeared, so whether the Nai He Bridge and the Ghost Gate Pass will also appear, whether it will be on the other side of the Lethe River, all of this cannot be explained.

Lei Yu's mind was in a mess, and entering this underworld was not what he thought. He wanted to get out of here, but there was no way out, and he was trapped in this underworld, which was very strange.

"Forget it, let's go along the Lechuan River! maybe you can really find the legendary Nine Shadows Sea. Lei Yu left the worries in his heart behind.

At this time, he didn't know where the way out was, so he could only rely on his own feelings.

Fortunately, his cultivation has improved a lot, and his whole body is full of qi and blood, in such a state, he at least has some self-preservation power, and he doesn't need to worry too much.

The road of fire spread out, and the fire was red, like a giant carpet, covering the banks of the Lechuan River. There are flowers but no leaves, and the flowers on the other side extend infinitely, forming a strange scene, which is amazing.

This is the only scenery on the Yellow Spring Road, where the flowers bloom on the other side, leading the yin spirits into the underworld of hell. Lei Yu didn't know if he would really go to hell, but now he had no other choice, he couldn't find a way out at all, and followed the Lechuan River.

Along the way, Lei Yu didn't go very fast. He continued to consolidate his cultivation and became familiar with the thunder of Lethe in his body.

This is a kind of Qilei, which is a combination of Lethe water and the mysterious power in his own body, and he is not very familiar. Now is the right time to take this opportunity to consolidate my cultivation.

He cultivated as he walked, his body was nothing, his eyes were closed, his hands were constantly pinching, and he deduced wonderful runes, and his whole body was shrouded in a layer of yellow light, which was extremely conspicuous.

He was evolving a move, even if Lei Yu consolidated the thunder of Lethe, but if there was no move, he would not be able to maximize the power of the thunder of Lethe.

"The flowers on the other side are blooming, and the Lethe River is coming. The opportunity to receive is all in my hands!" Lei Yu performed the move, only to see his hands constantly pinching, evolving all kinds of tricks. And as he moved, a fiery red picture suddenly appeared behind him.

This is the path of fire composed of flowers on the other side, which is quite peculiar, spreading into the depths of the distance, and there is an endless power deriving. Then the flowers bloomed all over the sky, and the flowers on the other side turned into petals and flew in the sky, and suddenly the sky was covered with a layer of flames.

"Boom!" The flame-like flowers on the other side were endless, and then suddenly a tidal sound sounded, and the sky and the earth cracked, and there were endless waves surging. The yellow water of the Lechuan River rolled in, and the flowers on the other side fell into the waves, and soon there was a strange change.

These flowers on the other side turned into pages of petal boats, galloping in the waters of the Lethe River, as if they were going to pick up someone, which was very weird.

"Ha Luha, I didn't expect that I would be able to produce such a change by integrating the artistic conception of the flower on the other side into the thunder of Lethe. The flower of the other side is the flower of guidance, which is dedicated to the soul that has entered hell. Now I use the thunder of Lethe River as the carrier, and the flower on the other side as a flat boat, to attract others, which is a wonderful killing move. ”

Lei Yu woke up from his contemplation and withdrew his moves, a smile on his face.

This time, he inadvertently thought of integrating the artistic conception of the other side flower into the thunder of Lethe River and created his own moves. If you say it, I'm afraid few people will believe it, after all, creating a self-created move is almost impossible for a Thunder Qi Stage cultivator to complete.

"It seems that I have walked more than 100 miles, but I still have not reached the end, and I don't know what the destination of the Lechuan River looks like. Lei Yu took a look at the surrounding environment, the path of fire was still extending, but the surrounding scenery had not changed, extremely dark, yin and ghostly qi were permeated, like hell.

It didn't take long for him to meditate this time, but in fact, he had already walked more than a hundred miles, mainly thanks to the continuous tempering of his body while cultivating, which made his speed faster, and before he knew it, he had walked more than a hundred miles.

"There were dry bones there, what seemed to be some beast or something. Lei Yu's gaze was drawn to a large dry bone.

This is a very large dry bone, more than 100 zhang long, the whole body is white, has been dead for a long time, buried in the Lechuan River, leaving only a white skeleton.

Lei Yu stretched out his hand to pull out this dry bone, but found that this dry bone had been combined with the filthy power in the Lechuan River, which was very difficult to pull out, even if Lei Yu's body was strong, but he still couldn't pull out this dry bone.

"I don't know what kind of beast this is, it's really strange that it would be buried here. After Lei Yu tried it, he decisively stopped, and instead focused his eyes on this dry bone.

Not much of the dry bones were exposed, and the head was buried in the black soil, leaving only a section of the spine that was often exposed to the ground.

With such little information, Lei Yu naturally had no way to investigate, so he could only put this matter in his mind. It's just that in this way, Lei Yu is much more cautious, and it seems that this road is not as easy as imagined.

His heart lifted, but he didn't flinch, and continued to move forward, but with much more caution.

This section of the road is not easy to walk, just walking about hundreds of zhang away, Lei Yu found another corpse. This corpse is much larger than what I saw before, and the corpse is also exposed, and it can basically be seen in its entirety.

"This beast has a peculiar appearance, a dog-headed fish, and it seems to grow in water. Lei Yu found something unusual, this corpse was very strange, Lei Yu had never seen it, and couldn't help but be a little contemplative.

There is no other river here except the Lethe River, but the Lethe River sinks when it encounters things, and this beast cannot be separated at all, and the only explanation is that this beast comes from other waters.

Lei Yu's eyes suddenly widened, and he thought of something in his heart, if he didn't guess wrong this time, the Sea of Nine Shadows should be not far away, and he was about to reach the Sea of Nine Shadows.

"The course of the Lechuan River here has become much wider, at least two or three times as wide as before, and generally only the mouth of the river has such a formation, it seems that it is really not far from the Sea of Nine Shadows. Lei Yu had a speculation in his heart, but he was even more curious, he didn't know what the Nine Shadows Sea of the Nine Shadows looked like, whether it was as vast as the legend.

Lei Yu left the corpse and continued to move forward, along the Lethe River. The river is getting wider and wider, and the mighty Lethe River is rolling down, and the water is much smoother, and it is about to enter its destination.

And the road of fire that has been spreading seems to have come to an end, and the flowers on the other side of the ground are decreasing, and they are not as red as before.

The mission of the Flower of Attraction is coming to an end, and what will be presented to Lei Yu will be an even greater Sea of Nine Shadows.

"The sound of flowing water in front of me is even louder, it seems that the mouth of the Lechuan River has arrived, and the yin qi, ghost qi, and all kinds of resentment are intertwined with each other, and they are even more powerful. Lei Yu's divine thoughts felt a majestic momentum, and the curiosity in his heart was even greater, and he couldn't help but speed up his pace.

"Is this the Sea of the Nine Shadows? Sure enough, it's vast and boundless. Half an hour later, Lei Yu stood aside, and in front of him was an incomparably vast water, pitch black, with endless resentment, yin qi, and ghost qi contained in it, it was the Sea of Nine Shadows.

The sea of nine secluded areas has remained unchanged for thousands of years, and there is no edge in sight. The sea water is black, deep and sinking, and all kinds of filthy power are contained in it, dozens or hundreds of times stronger than the Lechuan River, and it is no wonder that such a body of water should be described as the sea.

Lei Yu stood on the shore of the Nine Secluded Seas and only felt that his body was wrapped in a stream of yin and thunder qi, but fortunately, Lei Yu cultivated the thunder of Lethe River, which was able to wash away all kinds of filthy power, so he was not infected, but refined these filthy powers to replenish his body.

"There seems to be a small island there, at least a few dozen miles away. As far as Lei Yu's eyes could see, he saw a small island standing on the Sea of Nine Shadows, which looked very unique, and Lei Yu was suspicious at the moment.

"Xiaoyou, since you have arrived in the Sea of Nine Shadows, then please come to my island for a gathering, I have wanted to see Xiaoyou for a long time, and please don't excuse Xiaoyou. Suddenly, such a voice sounded in Lei Yu's ears. The voice was old, but it was full of energy, obviously from a master, which made Lei Yu feel shocked, could it be that there were still people living in this Nine Shadows Sea?
