Lei Hao doesn't have Su Ye's magical power to hide his breath, but he has a lot of magic weapons to hide his breath.

But if Lei Hao covers his breath, then he will inevitably suffer from the erosion of the gray demon mist, so Lei Hao simply gave up covering his breath, for him, these mutated demon beasts and human corpses are nothing, and the danger of the gray demon fog is even greater.

However, at this time, he regretted it, as soon as Lei Hao entered the Gray Dark Valley, it was like a flash of light in the endless night sky, and the vitality on his body was full of vitality, which naturally attracted a large number of mutant demon beasts.

At first, it just attracted some mutated demon beasts in the Jindan realm, and these demon beasts were eroded by the gray demon mist, although the strength was infinite, the skin was rough and the flesh was thick, and only the bloodthirsty instinct remained, for Lei Hao, it was just a thunderous thing.

But with Lei Hao's deepening, it was not only the mutant demon beasts of the Jindan realm, but also the corpses of the human race Tianjiao in the Yin God realm and the mutant demon beasts in the Yin God realm.

Killing all the way, with Lei Hao's incomparable combat awareness and combat experience, he didn't feel tired.

But now besieging him are dozens of mutant demon beasts of the Yang God Realm and the Terran Tianjiao. Among them, there were two demon beasts and a mutant Tianjiao whose corpse was the most powerful, comparable to a half-step cave void monk.

A lizard-like demon beast with two huge heads and a body of hundreds of feet, the lizard-like demon beast's eyes were red, full of tyranny, and there was no breath at all, but the gray demon fog on its body was extremely rich.

There is also a tiger-like demon beast with four pairs of wings, but it has been mutated by the gray demon mist, and those four pairs of noble and gorgeous wings are now extremely dry, and the mouth is full of bloodthirsty meaning with two fangs more than one meter long.

The last of the remaining mutated Terran Tianjiao, wearing a luxurious robe, although there were a few tattereds, it could be seen that the status in front of him was not bad, his face was blue, his eyes were white, and the blood vessels on his body were as if they were about to explode, which was clearly visible, and the thick gray demon mist on his body was like substance, which was thicker than the two demon beasts.

Lei Hao knew that these people and demon beasts were eroded by the gray demon mist, and the stronger they were, the richer the gray demon mist on their bodies.

Encountering the siege of dozens of Gray Immortal Slaves of the Yang God Realm, the ordinary Yang God Realm had already given up resistance with a face of despair.

But for Lei Hao, although his face was solemn, he was not afraid, and his eyes at this time looked at the black stone platform on a hillside two thousand meters away.

The Hundred Holy Cave Heaven has been open for tens of thousands of years, and it has been developed to the point of seventy-seven eighty-eight, but the Gray Dark Valley has always been a taboo in the Hundred Holy Cave Heaven.

In addition to the gray demon mist, the Gray Stygian Valley is also like a labyrinth, and few of the monks who entered were able to come out, let alone enter the core place.

Some monks once speculated that the Hundred Saints Ancestor's Hundred Saints Diagram should have been placed in the Gray Styx Valley, but after tens of thousands of years of exploration, in addition to the loss of countless monks, nothing was found, so the Gray Styx Valley was listed as a forbidden place.

However, Lei Hao held the Heavenly Machine Disk, and with the guidance of the Heavenly Machine Disk, of course, he easily went to the core of the Gray Dark Valley.

At this time, the black magnetic needle of the Heavenly Machine Disk in Lei Hao's hand finally pointed to the black stone platform on the small hillside.

The black stone platform was not big, but on top of it was a coffin made of purple gold, which was extremely luxurious, obviously hiding the corpse of the Hundred Saints Ancestor, and the Hundred Saints Diagram should be there.

Although this coffin made of special materials was engraved with countless runes, and no one could detect it at all, Su Ye could barely see it when he opened the Eye of Chaos.

There was a figure lying in the coffin, and there was a drawing-like thing next to it, which was obviously a hundred saints, thinking of this, Su Ye couldn't help but feel excited.

The Hundred Saints Ancestor is also both righteous and evil, and he is also a loose cultivator, without much background, plus he has obtained a trace of the origin of the gray demon mist, refining it into a high-grade supernatural power, plus the Hundred Saints Diagram, the Mahayana realm is almost invincible.

It was precisely because of this that the Hundred Saints Ancestor was finally surrounded and suppressed by the four first-class forces in the Northern Regions.

At that time, the four first-class forces dispatched hundreds of cave void monks, thirteen ancestors of the Mahayana realm, and four scattered immortal giants.

Legend has it that the battle was extremely terrifying, and the entire Northern Region was shaken, originally there were scattered immortal giants to make a move, plus after planning for a long time, even if the Hundred Saints Ancestor was almost invincible in the Mahayana realm, he was not an opponent, but the fact was that it was the eyes of most of the blind people.

In that battle, three of the four great Scattered Immortal Giants were killed, one of them was seriously injured, and as for the Mahayana monks and the cave void monks, none of them survived.

After that battle, the three first-class forces were reduced to second-rate forces, and the remaining power of the only remaining Mahayana realm ancestor barely remained at the level of first-class forces, but it was also reduced to the bottom.

And the Hundred Saints Ancestor is said to have exploded in that battle, and by the time the Hundred Saints Cave Heaven opened tens of thousands of years ago, only the Hundred Saints Ancestor had inherited and accumulated thousands of years of wealth.

But now it seems that the Hundred Saints Ancestor is not dead, but more than 40,000 years have passed since that battle, and even the scattered immortals have only survived for 38,000 years, and they are all old and dead if they don't die.

Just when Su Ye was thinking wildly, the group of gray underworld slaves who surrounded Lei Hao launched an attack on Lei Hao.

Although these gray underworld slaves have been mutated and strengthened, and their strength has increased greatly, they have no wisdom, only fighting instincts, otherwise Lei Hao will turn around and run away as soon as possible.

I saw Lei Hao thundering all over his body, and silver lightning burst out from his body, like silver thunder snakes, blasting towards the gray underworld slave who pounced on him.

Not only that, Lei Hao took out a silver halberd from the storage ring, but this halberd was a superb treasure, obviously being sacrificed by Lei Hao for a long time, the halberd was like a tiger in his hands, plus Lei Hao, who cultivated the double cultivation of the law body, it was simply a halberd split, instantly cutting a gray god slave in the early stage of the yang god in half.

But even so, the Grey Slave didn't shed blood, but continued to attack Lei Hao, who had killed so many Grey Slaves along the way, and of course knew their weaknesses.

I saw Lei Hao holding the halberd tightly in his right hand, and he pulled forward, instantly cutting off the neck of the gray demon slave, and the huge demon beast's head rolled down, and it didn't move directly.

The gray demon slave was originally a dead thing, because the gray demon fog gave them "life", so they were not afraid of pain, nor afraid of death, Lei Hao killed a gray god slave not only did not make them retreat, but felt the vitality in Lei Hao's body, more excited, more bloodthirsty.

Lei Hao's moves and styles were accompanied by the power of Thunder Heavenly Might, and he was faintly restrained from these gray underworld slaves, plus the gray underworld slaves had no sense of battle at all, so in less than dozens of breaths, dozens of gray underworld slaves in the Yang God Realm were killed by him, and only a few gray underworld slaves were left to support him.

As for the lizard-like gray underworld, it had been torn into countless pieces by Lei Hao, and the four pairs of withered wings behind the tiger-like gray-underworld slave had been cut off, and there were countless wounds on his body.

At this moment, Su Ye found that the Terran young Grey Underworld Slave seemed to be the king of this group of Gray Underworld Slaves, and when he saw that most of his subordinates were killed, he roared lowly, as if he was angry, and the whole person rushed towards Lei Hao like a bolt of lightning in an instant.

At this time, when the halberd in Lei Hao's hand was about to slash at the head of the tiger-shaped gray underworld, he suddenly felt a danger behind him, and he was vigilant in his heart, and the halberd that was originally slashed towards the tiger-shaped gray underworld instantly slashed to his back.

Bang!!!

A metal crash sounded, Lei Hao instantly retreated dozens of steps, looked up, and saw that the young gray underworld slave was holding a golden spear in his hand, and his eyes looking at Lei Hao seemed to be longing.

This gray god slave is actually conscious!

Lei Hao's heart was awe-inspiring, but the solemnity in his eyes appeared again.

At this time, Su Ye in the distance was also extremely surprised, this gray underworld slave actually had a simple consciousness, and he still had a body of combat experience, it seemed that Lei Hao couldn't be easy.

Bang! Bang!

Sure enough, as soon as Su Ye finished speaking, Lei Hao and the gray underworld slave instantly fought together, and the speed of the two sides was extremely fast, as if two afterimages were colliding with each other.

However, Su Ye suddenly discovered that not far from Lei Hao, in the other direction, there was a group of monks.

There were about a dozen monks in that group, both men, women, and children, and all of them had Yang God realm cultivation, and even the momentum of the old man led by him was a little more dignified than Lei Hao.

This made Su Ye secretly say that it was not good, it seemed that the situation had changed, and this group of people was clearly not the hundreds of young talents who came in.
