Lei Yu took a closer look, this White Bone Mountain was too spectacular, standing on the black plain, the white cold light was shining, and there was a sinister aura surrounding the White Bone Mountain.

It's a terrible scene, where hundreds of thousands, if not millions, of people are buried, gathering a sinister aura, and it's terrifying. Lei Yu was shocked, but he was a little curious in his heart. The Hell Demon Sect has arranged a mountain of white bones here, and there must be some secret in it.

"At the bottom of this mountain of bones are some ordinary corpses, and the higher you go, the higher the level of the corpses, there are not many shatters, and the heavier the yin qi that can be provided. Lei Yu came to the front of the White Bone Mountain, and felt the vastness of the White Bone Mountain more and more.

The white bones are like a mountain, and the white bones under them have been crushed and turned into grains of white powder, which serve as the foundation of the mountain of white bones. This is the most basic mortal corpse, and further up there are the corpses of many cultivators, the whole body is pure and translucent, and a little bit of yin and evil qi is gathering.

"It's a golden skeleton, I guess it must be the corpse of some kind of supernatural person. Lei Yu's gaze went up further, and some of them couldn't see clearly, but some golden light was flashing. It's not that kind of yin and evil aura surrounding, but there is a righteous and mighty aura rising.

This is the corpse of a great supernatural person, according to Lei Yu's estimate, at least a cultivator of the Lei Dan stage, otherwise the bones would not be like this. Cultivators in the Lei Dan stage are strong in cultivation, even if they are destroyed, the bones will not melt away, but will leave the ** characteristics of cultivation before death, showing a different appearance of corpses.

Lei Yu followed up and found several other corpses of different colors, all of which were great supernatural powers, and there were as many as five of them. Gold, blue, black, purple, and blue, the five corpses are located at the top of the White Bone Mountain, and the five auras are different, either evil or mighty, leading the entire White Bone Mountain.

"It seems that these five corpses are the true core of this mountain of bones. Only this level of corpses can dominate so many corpses. "Lei Yu stood at the foot of the White Bone Mountain, and he already had some understanding of the structure of the White Bone Mountain.

Using the corpses of five great supernatural beings to condense the White Bone Mountain, this method can only be done by a large sect like the Hell Demon Sect.

"There's a Yin Spirit there approaching the Mountain of Bones, see how this Mountain of Bones reacts. A yin spirit appeared in front of Lei Yu's eyes, his body was empty, floating in the air, as if he had come here unintentionally, without the slightest consciousness.

At this time, the Yin Spirit was still a hundred feet away from the White Bone Mountain, but Lei Yu could feel the movement of the White Bone Mountain. A sinister aura swept out, rolling up the yin spirit, and in an instant, the yin spirit turned into ashes, and it didn't even let out a scream, it was completely absorbed by the White Bone Mountain.

Lei Yu shuddered, this White Bone Mountain is definitely not a good stubble. Although he didn't know why the White Bone Mountain didn't do anything to him, Lei Yu still decided to leave here as soon as possible.

"Wow!" At this moment, Lei Yu felt a pair of strange eyes looking at him. His heart suddenly looked at the top of the White Bone Mountain, but he found that a pair of golden eyes were staring at him, indifferent and colorless.

This is the gaze of the golden corpse, I don't know when the golden corpse actually opened its eyes, it seemed to have life, staring at Lei Yu.

Lei Yu's forehead began to sweat, and he was enveloped by a coercion. Although the corpse was lifeless, the coercion of life was still there, but Lei Yu couldn't stand it anymore and wanted to flee immediately. Otherwise, if he angers this corpse, I'm afraid he will really be in trouble.

"Get out of here, this is not the place I can be. Lei Yu immediately made a decision to leave the White Bone Mountain and go elsewhere.

He mustered up all his qi and blood and began to flee, running into the distance, until he was out of the light of that gaze, Lei Yu really stopped. At this time, Lei Yu realized that he had run a distance of more than 100 miles, which was quite terrifying.

"Finally got rid of that gaze and could take a good rest. Lei Yu was a little tired, even though the body of his Nine Shadows Body was extremely powerful and his qi and blood were vigorous, but the distance of more than a hundred miles still made him a little panting and breathing a little unsteady.

He found a place to sit down and concentrate on recovering his qi and blood. At this moment, a strange sound came, which made Lei Yu wake up.

"Boom!" The sound of running water sounded on this plain, which was extremely conspicuous, and it was impossible for Lei Yu to ignore it.

This plain was too monotonous, and Lei Yu also felt a little upset. Now when he first heard the sound of flowing water, although he was still very cautious, he finally decided to check it out.

The sound of flowing water is non-stop, and it seems that there is a river rushing. Lei Yu gradually approached, and after walking for about ten miles, a wide river finally appeared in front of him.

"This is ......" Lei Yu was shocked in his heart, the river in front of him was very wide, several miles wide, and the river was dark yellow, flowing endlessly, flowing to an unknown distance. And on both sides of this river, a red is spreading, it is a red flower, with flowers and no leaves, like a dragon's claw, spread all over the river, spreading, like a flame burning.

Lei Yu's heart began to sink, and he remembered some legends, which were very similar to the scene in front of him, making him hard to believe.

"Could this be the Lethe River and the flowers on the other side!" Lei Yu said with some surprise, the scene in front of him seemed to be only explained by this.

The Lethe River, the legendary Styx River in Hell, is a yellow river with yin spirits and evil creatures in it, which is very wide and flows into the mainstream of the Nine Shadows Sea. It is rumored that the water of the Lethe River is not passable, and no matter what it falls into the water of the Lethe River, it will sink into the river, which is quite terrifying.

If you want to cross the Lechuan River, you can only wait for the ghost boat on the Lethe River, otherwise you don't want to cross it. And after crossing the Lethe River, there is the real hell and the underworld, which belongs to the dead.

And these flowers that spread all over the bank of the river are the flowers of the other side, also known as the Shezi flower, the manzhu sawa, the flower of the introduction, etc., which is a kind of hell flower. Paved with the banks of the Lethe River, it forms a path of fire, leading the yin spirits into the underworld, and is the only scenery in hell.

The scene in front of him was undoubtedly the same as the legend said, which made Lei Yu a little dumbfounded. Although Lei Yu had some speculations before, he didn't think that this was the real Hell Underworld. But now the scene in front of him has shaken his inference a little, is this really hell and the underworld?

"If you cross this river, you won't enter the real hell and underworld!" Lei Yu laughed to himself, still a little unconvinced. At this time, he still thought in his heart that this was arranged by the Hell Demon Sect to reproduce everything in hell.

"Is this the other side flower?" Lei Yu squatted down and looked carefully at the other side flower on the ground. The flowers were like fire, fiery red, like a burning flame, covering the banks of the river and spreading into the depths of nowhere.

This flower is the famous flower of hell, and it is rumored that the fragrance of the flower can awaken the memories of the soul during life. But at this moment, Lei Yu didn't feel this, he was still a living person, and his soul was still stored in the body, so naturally he wouldn't feel this way.

"It seems that this other side flower is not so miraculous. However, I can collect a few strains and study them. Lei Yu smiled and plucked a few other flowers, wanting to keep them for research in the future, but soon he found that this idea was not good.

As soon as the flowers on the other side of the ground dried up, they could not be preserved at all, as if only the underworld here could grow.

Lei Yu plucked a few plants, but without exception, all of them withered and disappeared into annihilation. Lei Yu frowned slightly, but he felt that there were all kinds of inexplicable forces brewing in the place where the flowers were planted on the other side, and it was this strength that allowed the flowers on the other side to grow.

"It seems that this other side flower really only grows in this kind of place. Lei Yu saw that new flowers began to grow in the place where they had been uprooted, red and bright like fire, forming a long path of fire.

"Bang!" At this time, Lei Yu's gaze began to turn to the Lechuan River. A water ghost in the river jumped out, shook his head fiercely, and roared desperately, trying to get out of the Lethe River, but soon after, the water ghost was swallowed by the water of the Lethe River, and could not make a little wave.

The river is forgotten, and it sinks when it encounters things. Nothing can float on it, and wanting to get out of it is even more delusional, impossible to achieve.

"That's ......," Lei Yu's gaze looked into the distance of the Lethe River.

The black fog was shrouded, the twilight was heavy, and it was not real, it seemed to be the appearance of a boat, and there was an old man holding the boat, and he was heading in the direction of Lei Yu. And around the boat, water ghosts kept appearing, surrounding the boat, as if they wanted to enter the boat, but they were all beaten back by the old man, and sank to the bottom of the river, never to rise again.

This is a ghost boat, appearing on the Lechuan River, very weird, Lei Yu is a little frightened. Everything here is the same as the legend, a ghost boat has appeared on the Lethe River to lure Lei Yu over.

"It's not to cross the river, I'm not dead. Lei Yu didn't know what to say, he was obviously a living person, but there was a ghost boat to pick him up and cross the Lechuan River, all this was too weird. But the facts are right in front of him, and he can't help but believe it.

The ghost ship gradually approached, dilapidated and seemed ready to capsize at any moment. The entire hull of the ship is black, black and faint, and I don't know how many years of immersion it has been. There was a skeleton in the bow of the ship, vicious and hideous. On the ship, a green oil lamp was hung, and the fire flashed, as if it could devour souls.

Lei Yu felt that his heart was beating faster and faster, the ghost ship was constantly approaching, about to dock on the shore, to pick him up, his heart had a trace of panic.

"Ding Ding Ding!" A crisp sound came, exceptionally quiet, faintly on the Lechuan River, as if urging people to board the boat.

This is a strange scene, but it makes Lei Yu extremely frightened and a little frightened.

The ghost boat docked, stretched out a plank, and set it up on the shore. The old man on the boat had a yellowish face, his face was expressionless, holding a penny, standing on the boat, waiting for Lei Yu to get on the boat.

ps: The Lethe River and the Santu River here have wine and boil down to the same river, so in the future, there will only be the Lethe River, and there will be no Santu River, so you don't have to dig into it.
