Looking at the gray strange mist that shrouded the entire valley, Lei Hao frowned in his heart.

"Gray Demon Mist, there's some trouble. ”

The gray demon fog is one of the innate spiritual fogs born between heaven and earth, which can corrode the power of magic weapons, such as a superb treasure weapon, which can corrode a descending grade to a high-grade treasure weapon, or even a medium-grade treasure weapon.

And the Hundred Saints Ancestor once obtained a wisp of gray demon mist origin, and it took thousands of years to refine it into a high-grade supernatural power, and it was a great reputation.

At this time, this gray demon fog that stretched for hundreds of thousands of miles had already become the climate, and although it had no owner, it was not something that could be subdued by the ordinary Mahayana realm.

Due to the fusion of the ethereal fruit core and the Hundred Holy Cave Heaven, only monks below the Cave Void Realm were allowed to enter, and the demon beasts inside could not surpass the Yang God Realm.

Therefore, he knew that there was a gray demon mist that stretched for hundreds of thousands of miles, but no monk could collect it, and once he forcibly broke through the Hundred Saints Cave Heaven, there was a ninety percent chance that the entire Cave Heaven would explode.

Once the cave sky explodes, all the demon beast elixirs in it, including the ethereal grass and the gray demon mist, will disappear, which is also not allowed by the Great Xia Dynasty.

The Great Xia Dynasty sent a B-level Mahayana realm worshipper to guard the Hundred Sage Cave Heaven, not only for the Ethereal Grass, but also for this large area of Gray Demon Mist.

Looking at the gray but corrosive mist in the valley, Lei Hao's face remained unchanged, only to see that he took out a fist-sized blue bead in his right hand, which was obviously a magic weapon of no lower level, and there were words in his mouth, as if he was reciting some kind of incantation.

As soon as he finished reading, the blue in his hand instantly bloomed with a brilliant blue light, and flew directly above Lei Hao's head, forming a blue canopy with a range of tens of meters, like a blue sea water, forming a strong contrast with the gray in the valley.

After doing all this, Lei Hao was expressionless, raised the Tianji Disk in his hand, and walked straight to the valley.

Lei Hao went in for a few minutes, and a figure appeared outside the valley, it was Su Ye, at this time, Su Ye looked at a large area of thick gray demon mist in front of him, and frowned slightly, Lei Hao has a magic weapon to defend against gray mist, but he doesn't have it.

Su Ye took out a low-grade treasure from the system space and threw it directly into the valley, with the eye of chaos, Su Ye could clearly see that the low-grade treasure was shrouded in the gray demon mist, and the treasure light emitted from the treasure immediately dimmed, I believe that it will not be long before it will become a mass of scrap copper and rotten iron.

Seeing this scene, Su Ye's heart was awe-inspiring, the gray demon mist could not help but corrode the magic weapon, and it could also corrode the mana, body and soul, with the pill on his body and the cultivation of the peak of the early stage of the Yang God, it would not be a problem to last for dozens of days at most,

But Su Ye understood that the closer he got to the innermost part of the valley, the greater the concentration of the Gray Demon Mist, the longer the corrosiveness would be, and the shorter the time he would hold on.

And Lei Hao is different, he has that special magic weapon and has definitely lasted longer than him.

Although it was said that Su Ye could block Lei Hao outside the valley, Su Ye felt that it would be safer to hang behind Lei Hao and wait for Lei Hao to find the Hundred Sage Diagram before making a move.

After all, there is a gray demon mist to isolate the aura of the outside world, and you have to rely on yourself to recover mana inside, so some hole cards that rely on the aura of the outside world must not be used.

Of course, Su Ye is not afraid of competing for the elixir, and the gray demon mist can isolate the transmission of information, and can even isolate talismans such as space, so he is not afraid that Lei Hao will directly cast his hole cards and tear the void and escape.

Thinking of this, Su Ye did not hesitate, ran the Heavenly Emperor Sutra, and emanated a golden aura enveloping his body, and walked directly into the Gray Dark Valley.

As soon as Su Ye entered the Gray Styx Valley, the surrounding Gray Demon Mist felt the breath of living beings instantly enveloping Su Ye, but to Su Ye's surprise, as soon as the Gray Hades Demon Mist touched the mana of the Heavenly Emperor Sutra on Su Ye's body, it was like encountering a natural enemy, and it directly faded away, as if he was afraid.

This also caused a clearing to be formed within three meters of Su Ye's surroundings, and there was not the slightest gray demon mist coming in.

Since cultivating the mana in the Heavenly Emperor Sutra can resist the Gray Demon Mist, then the Chaos Dao Body should also be able to, after all, the Heavenly Emperor Sutra is the most suitable exercise for the Chaos Dao Body, also known as the Chaos Dao Sutra.

When it came to it, Su Ye was not a hesitant person, and directly withdrew the golden aura shrouded in his body, allowing the gray demon mist to corrode his body.

The gray demon mist seemed to be conscious, and after feeling that the golden aura shrouded in Su Ye's body disappeared, it surged towards Su Ye like a tide, instantly enveloping Su Ye's entire person.

Hiss~~

Su Ye secretly took a breath of cold air, as soon as the gray demon mist touched his body, because there were clothes on his body, it had not been corroded yet, but his hands and head were as painful as pins and needles and peeling, and even Su Ye could feel that the skin on his face was being worn off little by little, and the blood was slowly flowing down.

Su Ye's chaotic Dao body sensed the danger in his body, and if Su Ye looked inside, he could see that the countless lines in the lilac bones all over his body were like flowing mysterious runes, emitting dazzling purple light.

Under the illumination of the purple light, the gray demon mist that had originally eroded into Su Ye's body was instantly forced out of his body, as if he was guarding his own territory.

Su Ye could feel the surging qi and blood all over his body, like a dragon, like a divine beast cub, and the power of qi and blood overflowed out of his body.

Under the two changes of the gray demon mist and the purple light urging qi and blood, Su Ye was in great pain, as if he had been punished, and the pain in his body made him feel slightly numb.

But under this mutual wear, Su Ye could feel that the skin was constantly proliferating, and it was also constantly destroying, and each cell was greedily absorbing the gray demon mist, as if using the gray demon mist as a kind of body refining treasure, Su Ye could feel the power of the body slowly growing.

This made Su Ye's heart full of excitement, and even the pain was forgotten a lot, this gray demon mist seemed to others to be an incomparably terrifying demon mist, but for himself, it could be described as a quenching treasure, and the more he went into the depths, the greater the effect, which made Su Ye sigh that this trip was worth it.

You must know that cultivating the physical body, the further you go, the more difficult it becomes, what you need is chance and luck, after all, refining the body not only depends on perseverance and exercises, but also on resources, and the resources consumed by refining the body resources are much more terrifying than refining qi.

After Su Ye got used to the pain in his body, he took a serious look at this gray valley, and saw that there were countless ancient trees hundreds of zhang high, or even thousands of zhang, growing in the valley.

Unlike the lush primeval forests outside, these ancient trees had long since been deprived of vitality due to the erosion of the gray demon mist, and only a dry trunk remained rooted in the earth.

The whole valley was like a black earth, extremely hard, and there were no plants growing except for countless ancient trees that had lost their vitality.

Moreover, the gray demon mist can also isolate vision and divine sense, if it weren't for Su Ye's Eye of Chaos, with his Yang God Realm's cultivation, he would only be able to see clearly within a range of hundreds of meters.

The gray demon fog has been entrenched in this valley for tens of thousands of years, and the entire valley has been eroded by the gray demon mist, so the demon beasts inside have mutated, and they are more fierce than the demon beasts in other places, comparable to the alien species among the demon beasts.

To be precise, there are no living demon beasts in this, but the corpses of demon beasts controlled by the gray demon mist, like dried corpses, only the instinct to kill remains.

And in addition to the demon beasts, the Hundred Holy Cave Heaven has been opened hundreds of times in tens of thousands of years, and several young talents of the past generations have died in it, and the corpses after death have been transformed by the gray demon mist, which is no different from those demon beasts.

These mutated demon beasts and the mutated Terran Tianjiao have a unified name, "Gray Slave".

In Su Ye's opinion, these mutated monsters and human corpses are no different from the zombies in the movies in the previous life, but the difference is that these mutated monsters and human corpses are stronger.

Su Ye wants to be Voldemort to follow Lei Hao, so it is impossible to release the vitality to these gray slaves to perceive, otherwise once he does it, he will be discovered by Lei Hao, and the sneak attack will not be successful.

Therefore, while Su Ye used the gray demon mist to quench his body, he also exerted his magical powers, and absolutely stealthily concealed his breath, in the eyes of those gray demon slaves, Su Ye was a stone.

At this time, Lei Hao, who was thousands of miles away from Su Ye, was encountering an unprecedented crisis.
