Hell Demon Sect, Lei Yu hadn't heard of it before, and he didn't know which sect in Yunzhou this was. But since he was able to establish his own power in the Netherworld, Lei Yu believed that the strength of this Hell Demon Sect was definitely not bad, at least the Zixiao Sect could not compare to it.

Lei Yu squatted down and carefully observed the stone tablet. The stele is not very large, it is very simple, and it is made of refined iron. But Lei Yu found that there was still a trace of the master's mark on this stone stele, if there was any external force to hit this stone stele, this trace of the master's mark would mobilize the nearby Yin Thunder Qi to resist these external forces, which was also the reason why the corpse could not break the stone tablet just now.

"Could it be that the power of this Hell Demon Sect has enveloped the entire Netherworld?" Lei Yu muttered to himself, it was hard for him to believe that such a sect still existed in the Netherworld. But what he saw at this moment did not allow him to believe it.

The Netherworld Forest, with a radius of thousands of miles, is immeasurably immeasurable. If the Hell Demon Sect really occupies the Netherworld, you can imagine how powerful this Hell Demon Sect is, at least the Zixiao Sect and the Seven Great Families of Yunzhou will definitely not be able to compare with it.

"It seems that what the robed Yin Ghost said is right, all the big sects will build domain gates for their disciples to travel. This Hell Demon Sect is so powerful, I'm afraid that there really is a domain gate inside this Netherworld Forest. Lei Yu began to believe in the words of the Dao Robe Yin Ghost, and a trace of confidence couldn't help but rise in his heart, and he was no longer as nowhere to be found as before.

"Let's go, keep walking, I'm going to reach the interior of the Nether Forest, enter the Domain Gate, and leave here with the power of the Domain Gate. Lei Yu secretly made up his mind to continue walking, and the distance into the Netherworld Forest was getting farther and farther.

"How can there be a white bone graveyard here!" Three days later, Lei Yu walked forward for a distance of more than thirty miles and came to a white bone graveyard. A piece of white bones was scattered on the ground, and the clothes on his body should have been hundreds of years old.

There were hundreds of these white bones, lying on the ground, and the weapons around them were scattered on the ground, all of them were some thunder soldiers, who had lost their essence and became mortal.

"That's Jiuyang Refined Iron, Fallen Iron!" Lei Yu picked up a broken sword, the body of the sword was rotten and tattered, but Lei Yu saw at a glance that the material used to cast this sword was actually made of Jiuyang Refined Iron and Fallen Iron, which was very rare. It's just that now this thunder soldier has become a mortal thing, has lost its essence, and can no longer be used.

"It's a pity that such a good thunder soldier was shattered like this. Lei Yu shook his head and sighed with some pity.

Thunder soldiers also have a time limit, and if they don't have refined temperature, they will also decay. This is the normal state of heaven and earth, and there is no way to change it.

"These people are all strong men in the Thunder Gang Period, and the weapons scattered around are all thunder soldiers, which is very good, I don't know how these people died, were they killed by the Yin Soul Evil in the Netherworld. Lei Yu looked at all the hundreds of white bones one by one, and found not a single usable thunder soldier.

His brow furrowed, a little strange. It is said that the cultivators of the Lei Gang period are already very powerful, and the Yin Soul Evil in the Netherworld, as long as they are not particularly perverted, should be able to survive the Netherworld Forest safely. But now that so many Lei Gang period powerhouses have died here, Lei Yu's first feeling is uneasiness, as if there is some conspiracy.

"This is?" Lei Yu stopped and walked towards a white bone. He held a sword in his hand, and beside him was a stone with a few words carved on it, very messy, apparently carved by the man before he died.

"Hell Vault, it's really a dead end!" The nine words were clearly visible, but they made Lei Yu's heart skip a beat, and the confusion in his heart was unraveled, I am afraid that the purpose of these people is still the hell vault, and they want to get the hell vault, so they are fighting here, but in the end, they all die and become a pile of white bones.

Lei Yu shook his head and sighed a little, but he didn't intend to stay here. No matter what, Lei Yu had to go to the interior of the Hell Demon Sect and leave this Netherworld Forest with the help of the domain gate.

He left the place and continued on his way, but the road ahead was getting harder and harder. The interior of the Netherworld Forest is very extraordinary, the aura of Yin and Thunder is rich to a limit, and the surrounding Yin Soul Evil Objects have also greatly increased, among which there are even Yin Soul Evil Objects whose cultivation is comparable to that of the Thunder Gang Period, which is very difficult.

"Whew, that three-headed yaksha didn't chase after me!" Lei Yu palpitated, lying on top of a tall tree, rarely having a chance to breathe.

This is the fifth day that Lei Yu has come to the Netherworld Forest, and he has probably walked more than a hundred miles. After passing through the White Bone Graveyard before, Lei Yu obviously felt the increase in the number of Yin Soul Evil Things around him, and the chance of him being found also greatly increased, and he broke through with his own physical strength along the way.

It's just that the day before yesterday, he was discovered by a three-headed Yaksha, who had been following him closely, and was very difficult, and almost died at the hands of the Yaksha.

The three-headed Yaksha had the cultivation of the Thunder Gang period, and Lei Yu couldn't fight at all, so he could only keep running away. Fortunately, Lei Yu found it early, so he escaped and was not eaten immediately.

Lei Yu stayed on the tree, gasping for breath. At this time, his body was already in tatters, skinny, his face was full of dust, his hair was also messy, and his body had lost a lot of qi and blood, and he was a little weak.

He glanced behind him with trepidation, and made sure that the three-headed yaksha hadn't chased after him, so he took out a bag of dry food from the space bag and nibbled on it. After these five days of walking, he was already exhausted, without the slightest strength, and needed to replenish his strength.

"Fortunately, there is dry food in the space bag, otherwise I would have starved to death if I hadn't been eaten by the Yin Soul Evil Thing. Lei Yu laughed at himself and gulped down the dry food in his hand. At this time, he did not have the slightest thunder power in his body, and he could only rely on his physical strength, which was the foundation of his life, and he had to pay attention to it.

"It's coming!" Lei Yu stopped the dry food he was eating and listened intently. At the same time, his thoughts were also scattered, and he observed carefully.

Lei Yu was helpless, in his divine thoughts, a three-headed Yaksha was coming quickly, chasing after Lei Yu, making him uneasy.

"Is that three-headed yaksha a dog's nose? Lei Yu couldn't help but curse secretly, but he quickly left the big tree and moved forward. Compared with the Thunder Gang Period, there is no doubt that one is heaven and the other is earth, there is no comparison, he can only choose to escape.

Lei Yu jumped forward, his body was dexterous, and he shuttled through the dense forest, very agile. In these five days, his speed has also increased a lot, and it will not be as difficult as before. Those dense forests are no longer obstacles, but tools that can be used, jumping in the air, Lei Yu is in good shape, a leap has a distance of more than ten zhang, in a short time, Lei Yu has advanced more than a mile.

"No, I've got to go faster, or I'll be caught up by these three yakshas. Lei Yu's divine thoughts felt behind him, and the three-headed Yaksha was in hot pursuit, getting closer and closer to Lei Yu, and Lei Yu could even see the body of the three-headed Yaksha clearly with the naked eye.

The three-headed Yaksha had an ordinary human body, all blue, with only a strip of animal skin around its waist. He was born with three heads, each of which was different. One of the middle heads was very ugly, with a face full of furrows and pits, as if it had been disfigured. The head on his left side is the head of a female human, with her eyes closed, but it is a little delicate. The skull on the right is the head of a human male, with an ordinary face and closed eyes.

Behind him was a pair of bat wings, and every time he flapped, there was a force that propelled him forward, very fast, even faster than Lei Yu.

"The human beings in front of me stand up for me, and obediently give me enjoyment. Otherwise, you will suffer untold suffering, and you will not be able to die, you will not be able to survive. Quack, it's been a long time since I've eaten the flesh of a living person, and I'm going to eat enough today. The skull in the middle smiled darkly, and the ravines moved, more terrible than the devil.

Of course, Lei Yu didn't pay attention to the clamor of the three-headed yaksha, but instead sped up and continued to move forward.

"Look for death, boy. Seeing this, the three-headed yaksha was furious, and a pair of bat wings flapped, driving a yin wind to sweep towards the thunder feather.

When the yin wind hits, there are all kinds of yin and thunder qi in it, once it is contaminated, it will enter the body, causing great damage to the body.

Lei Yu naturally knew the terrible yin wind, but he was not afraid, a fist, the golden brilliance shone, his qi and blood were vigorous, the fist of his right hand burst out, and a burst of masculine aura emerged, forming a gust of yang wind, opposite to the yin wind, and extinguished it.

"Hmph, if you want to catch up with me, that's a dream, I'll go first. The corners of Lei Yu's mouth twitched a little, but he was not relaxed, but instead urged the strength of his whole body to continue to move forward. He knew that as long as he got to one place, he could avoid the pursuit of the three-headed yakshas.

"There is the palace not far ahead, and as long as I get to the palace, I will be safe. A ruined palace appeared in front of Lei Yu's eyes.

The palaces are clustered, but they are dilapidated, and the interior of the Netherworld Forest is eerie. There is a strong aura of yin and thunder around it, surrounding it and preventing people from approaching.

This palace was discovered by Lei Yu during this time, and he guessed that it might be something left by the Hell Demon Sect, surrounded by formations. As long as they are within the range of the thunderstorm, the three-headed yaksha will not dare to approach, and it is a safe place.

"Boom, boom!" Suddenly, there was a shaking of the ground, and the sound made the ground buzz.

This voice was getting closer and closer, and Lei Yu's face also changed. This kind of momentum can only be found by that kind of powerful Yin Soul Evil Thing, could there be other Yin Soul Evil Thing coming here? Lei Yu was shocked in his heart, but he quickened his pace again and rushed towards the palace.
