This is a blood-colored ocean, and the endless blood-colored waves ripple a crimson light above the sea, as if people feel that they are surrounded by endless blood, and they can't help but fear in their hearts, and it is difficult to resist.

The boundless sea of blood, boundless, this is a vast sea, far beyond the imagination of ordinary people. However, what makes the Infinite Sea of Blood famous is not its vastness, but its endless blood that permeates it.

This is completely a sea made of endless blood, and everyone who really sees this sea of blood can't help but have a trace of fear in their hearts, because there are too many creatures buried in this sea of blood, and there is a rolling blood aura permeating the sky over the sea of blood, so that the entire sea of blood is shrouded in a layer of blood-colored clouds, and at a glance, the sea and sky are the same color, all surrounded by blood.

In this sea of blood, it is not that there are no living beings, they live in the sea of blood, they have completely adapted to the environment of the sea of blood, and they are integrated with the sea of blood, which is extremely difficult. Therefore, the Boundless Blood Sea is also called a forbidden place like the Burial Heaven Ridge, and few people can step into the Blood Sea, let alone enter the center of the Boundless Blood Sea, the Blood Demon Mountain.

But at this moment, a crack quietly formed in the sky above the sea of blood, and out of it came a young man, it was Lei Yu. He stood on top of the sea of blood, paying attention to all this, his brows furrowed slightly, he could feel the danger in the sea of blood, it was an existence that was even more dangerous than the Burial Heavenly Ridge, even the powerhouses of the Immortal Thunder Stage did not dare to set foot in it easily.

"This boundless sea of blood is the territory formed by the fall of the Blood Demon King, and it is the accumulation of the essence of his whole body. However, in this way, the body of the Blood Demon King also directly turned into a sea of blood and ceased to exist. If the sect master wants to find the body of the Blood Demon King, it is simply impossible, but if it is just to find the Demon King Order, it should be enough!"

In the crack, unable to walk out, he said slowly, there was a trace of sadness in his eyes, whether it was the Corrupted Demon King or the Blood Demon King, they were all the Demon Kings of the Hell Demon Sect, and their fall was also a huge loss for the Hell Demon Sect.

Lei Yu nodded, and didn't say anything, the Blood Demon King was different from other demon kings, he himself was transformed by a drop of essence blood, so if he fell, he would naturally turn into the original state, and this boundless sea of blood was its embodiment.

"No, you know the situation here best, how far are we from the Blood Demon Mountain now?" Lei Yu asked, he used the Spatial Crossing Technique to directly come to the Boundless Blood Sea, but there was still some distance from the real Blood Demon Mountain.

"Returning to the Sect Master, in fact, the old man has lived in the Burial Heavenly Ridge for a long time, and he doesn't know much about the situation of the Boundless Blood Sea, but judging from the scene here, we should be on the edge of the Boundless Blood Sea now, and there are at least tens of millions of miles away from the Blood Demon Mountain in the center. ”

Unable to think for a moment, he said cautiously, this distance he could see and hear based on what he had seen and heard, and he himself was not very clear, it was just a reference.

"Tens of millions of miles?" Lei Yu lowered his head and pondered, with his current cultivation, not to mention tens of millions of miles, even if it is more than 100 million miles, as long as he wants to go, he can reach it in a short time, but in the boundless sea of blood, he must be cautious, after all, there are too many unknown dangers here, and if he is not careful, he may fall.

Therefore, after a while, Lei Yu made a decision, these tens of millions of miles, he didn't need to travel through space, and flew over directly. It's a bit time-consuming, but it's better than putting yourself in danger.

"In that case, let's leave now!" Lei Yu didn't hesitate much, his figure flickered, and he headed towards the center of the Boundless Blood Sea. As for the impossibility, it turned into a phantom and returned to the "Nine Nether Thunder Bells" again.

The boundless sea of blood is extremely vast, and at a glance, it is blood-red, and there is no other color. And above the sea of blood, there are scattered islands, all of which are not very large, and all of them show a degraded color, as if they are about to disappear.

Lei Yu flew in the void, but there was no danger, after all, with his cultivation, as long as he exuded some aura, no living creature would dare to provoke him, but this did not mean that there was none.

The sea of blood is too vast, vast and boundless, and there is an endless amount of bloody qi breeding, so that the corpses buried in the sea of blood have also been replenished, and they once again have spiritual wisdom and become a kind of intelligent beings.

They are hidden in the vast sea of blood, it is difficult to detect, and only when they get close can they feel their existence, and this is how Lei Yu almost fell into the trap of these "creatures" several times, although it did not hurt Lei Yu in any way, but it made his heart more vigilant.

Fortunately, there was no danger in the next journey, Lei Yu walked all the way, and soon, a blood-colored mountain appeared in his eyes. It was a bare mountain of blood, with no color but red.

It was ten thousand feet high, standing above the boundless sea of blood, piercing through the clouds above the sea of blood, and it was extremely majestic. A thick bloody aura emerged, and this mountain seemed to gather the endless bloody aura of the boundless sea of blood, so that when facing this great mountain, he had the feeling of facing a demon king.

Of course, this is just a feeling, and Lei Yu will not take it seriously. However, despite this, Lei Yu's heart was still very shaken, he had also thought about the scene of the Blood Demon Mountain before, but he didn't expect it to be like this, it was completely unexpected by him.

"Is this the Blood Demon Mountain?" Lei Yu's divine thoughts naturally radiated towards this great mountain, but there was a faint force that blocked his divine thoughts from probing, so that he had to stop after only going dozens of feet deeper.

He didn't think much about it, he took a step and stepped directly on the Blood Demon Mountain, where he entered, it was red, this mountain seemed to be soaked in blood, and every inch of the land was red, so that he had a feeling that what he stepped on was not the land, but a huge body.

"Boy, take out your Demon King Order and see if there are any fluctuations on it?" a dark voice sounded, reminding.

Lei Yu nodded, the light in his hand flashed, and the Demon King Order appeared, floating quietly in front of Lei Yu. Each of the ten demon kings of the Hell Demon Sect has its own demon king order, and there are also some hidden inductions between these demon king orders, even if the owner falls, this induction will not disappear.

Therefore, using the Demon King's Order to probe the Demon King's Order is the best way. It's just that when Lei Yu was full of expectations to find out the Demon King Order of the Blood Demon King, the Demon King Order in his hand did not move at all, just like an ordinary token.

This situation is so abnormal, and a trace of bad premonition suddenly rose in Lei Yu's heart. His right hand flipped over, and two more Demon King Orders appeared in his hands, these were the Demon King Orders of the Ice Devouring Demon King and the Heavenly Spider Demon King, both of which he pocketed and rarely took out.

But at this moment, Lei Yu can't care so much. The three Demon King Orders were taken out together, but the result was still the same, without the slightest movement.

"What's going on? Could it be that the induction between the Demon King Orders has disappeared? Impossible, this is absolutely impossible, you must know that the Demon King Decree of the Dao is refined by the 'Nine Shadows Emperor' himself, and there is a trace of the essence blood of this Emperor contained in it, and this situation will never happen. ”

There was surprise in the dark voice, he didn't expect such a result, and his eyes widened as if he couldn't believe all this.

"There is no problem with the Demon King Order, then there is only one explanation, that is, the Demon King Order of the Blood Demon King is not here at all, it has long been gone!" Lei Yu said indifferently, a chill appeared in his eyes, no matter what, the Demon King Order is his must-have, if anyone wants to take away the Demon King Order, they will definitely bear his wrath.

"Lei Yu, find all this Blood Demon Mountain for me, even if I dig three feet into the ground here, I will find the Demon King Order!" Now it's not just Lei Yu, even Yin Ying is starting to be more serious, he doesn't allow the Demon King Order to be in the hands of a person who is not a Hell Demon Sect.

Lei Yu didn't refuse, although he already had an idea in his heart, but before he really confirmed it, he still wanted to find the entire Blood Demon Mountain. Only in this way can he truly die and have real peace of mind.

The entire Blood Demon Mountain was thousands of feet high, stretching for thousands of miles, and it was not easy for Lei Yu to find it in such a vast area, especially when his divine thoughts were restricted, but fortunately, with the help of Yin and Nether, the search was quite smooth.

But Rao was like this, and it was already a day after they searched the entire Blood Demon Mountain. During this search, they also found some suspicious points, the biggest of which was a cave located on the mountainside of the Blood Demon Mountain.

The aura that permeated this cave was so strong that when he first felt this cave, Lei Yu thought that there was an immortal thunder stage powerhouse in this cave, but after careful analysis, he ruled out this possibility.

At this moment, Lei Yu was standing in front of this cave, his divine thoughts radiated out, but he couldn't probe into a distance, as if there was some kind of formation prohibition arranged in this cave, which could isolate the exploration of divine thoughts.

"Boy, there's something weird in this cave, I feel some danger, you'd better not enter, just let that puppet into the cave and see what's going on. Yin Ming said a little gloomily.

"Senior, is this really that dangerous?" Lei Yu's heart sank, there are not many places that can make Yin Ming say that it is dangerous, and it is conceivable that there is any horror in this cave.

"I don't know what's in it, but there is a coercion pressing on me, even if I can't resist it!" Yin Ming said, although it was very calm, Lei Yu could hear a trace of palpitations.

Lei Yu's face was gloomy, it seemed that the plan he had entered was about to change, and the current situation could only allow the puppet to enter. Thinking of this, he didn't hesitate, patted his spatial ring, and in an instant, a giant with a demonic aura all over his body appeared in front of Lei Yu's eyes.

This giant is more than ten feet tall, and his body is full of evil energy, like a demon god, but his eyes are blank, and he has obviously lost his senses.

"Go ahead, take a look at what's inside?" Lei Yu ordered, this puppet was the giant of the Immortal Thunder Stage, and now it could be used to explore the way.
