Black sand dunes, as the name suggests, are black sand dunes.

There is no life here, only a pitch-black sandy hill, stretching for tens of thousands of miles, permeating with an eerie and mysterious atmosphere.

Flying all the way, Lin Yi was secretly surprised, looking at the increasingly black sand and dust, he felt a little strange. Curiously, he grabbed a handful of sand and inspected it, but found nothing, only a vague sense that the sand was infected by some force.

He wondered how the more he advanced, the darker the sand became, as if it had been formed by some force. The most amazing thing is that there is not even a single plant here, as if you have come to a land of death, and everywhere is full of dead silence.

Kindness?

Suddenly, Lin Yi's figure paused and muttered, "Sure enough, there are a large number of demons gathered, so powerful demon qi." ”

Ahead, in the rolling hills, one powerful aura after another permeated, extremely fierce, these are the breaths of demons, there are many of them, and they are terrifying.

"Weasels, why do you say we're here on patrol? There isn't a single hair here, let alone a figure, so I don't think there's any need to patrol. ”

Not far away, two demon figures walked quickly and were patrolling. The two demons didn't see a figure hidden behind the sand dunes, and one of the demons muttered obscurity.

The demon was born burly and hideous, with a row of sharp barbs on its back, shimmering green, and these spikes were poisonous. Lin Yi could see at a glance that this was a monster made of a hedgehog, and the green spikes all over his body were highly poisonous.

Next to it was a diminutive spirit with a thief's eyebrows. Looks savvy. It's a weasel. Covered with yellow hair. Although his strength is not very good, he is born with poison gas, which makes creatures faint due to fatigue.

After hearing this, the weasel scolded: "Green-haired, how can you and I guess about the king's affairs, be careful that the king will punish you." ”

However, after speaking, it glanced around cautiously before whispering, "You don't know, I can see it." A few Heavenly Demon Lords can be in that vein, and I even once saw the Heavenly Demon Lord respectfully bring an adult into it. ”

"No, even the Heavenly Demon Lord is respectful, what kind of character is it?" Greenhair was taken aback for a while, a little incredible.

The weasel shook his head and muttered, "Who knows, but I'm sure it's a big shot." ”

The two demons walked quickly, and behind the dunes, a figure flashed out. Lin Yi was secretly surprised, from the unintentional conversation between the two demons. Got a little bit of information here.

There are several Heavenly Demons here, and even the mysterious figure that he cares about the most is the one he cares about. Even the Heavenly Demon was respectful, thinking that it must be some kind of big man, or a powerful giant demon.

"There's a vein here, go check it out." A thought flashed in Lin Yi's heart, and it disappeared in an instant.

He was cautious, hiding his aura, even ethereal, the mysterious avenue of fate to cover himself, and sneaked towards the center of the black dunes.

Along the way, Lin Yi was shocked in his heart, there were too many demons here. Just by patrolling, I encountered more than a dozen waves of demons, although not very good, but there are many of them, and once they are discovered, they are likely to cause a huge riot.

He didn't want to alarm these demons, so he tried his best to hide himself and quietly entered it. He felt that there were at least tens of thousands of demons gathered in this place, which was really amazing.

I am even more sure of the guess in his heart, there must be a secret here, otherwise why do so many demons occupy this place, thousands of miles of lifeless sand dunes, no one will believe it if there is no weirdness.

One powerful aura after another is distributed here, team after team of demons patrolling, three steps and one post, five steps and one sentry, if it weren't for Lin Yi being strong enough, and he could hide himself, and even have supernatural powers, it would be really difficult to quietly enter here.

Hey?

Suddenly, approaching the core of the black sand dune, Lin Yi directly stopped his figure, his face full of surprise. He looked ahead, the void was filled with a mysterious aura, the light was dotted, and when he looked closely, it turned out to be some symbols.

These symbols were imprinted in the void, and even carved beneath the soil layer of the dunes, forming a huge and complex demon array. It's amazing that the demon array is branded here, but this is not difficult for Lin Yi.

His array comprehension, as he went all the way, got deeper and deeper, and he didn't even know what realm he could reach, although it was a little troublesome to deal with these demon arrays, he still didn't care.

He hid here and began to comprehend these demon formations, which was something that had to be done. There is a demon array here, and the demon patterns are intertwined, and if you accidentally touch it, it will attract the attention of the demons.

The demon array, speaking of which, also belongs to the formation path, but the power used is different. Therefore, comprehension is not as laborious as imagined, Lin Yi's formation realm is very high, and the comprehension speed is naturally not a problem.

It didn't take long for him to basically see through the demon array here, which was an incomparably large and complex formation. This array, with the help of the mysterious power of the entire black sand dunes, is connected, one after another, intertwined into a whole, huge formation.

I only guess that this array is very powerful, and ordinary people will definitely be in trouble if they accidentally break in.

Swish!

Lin Yi, who was comprehending the demon array, suddenly disappeared here and hidden. Then, a group of demons came not far away, this is a group of powerful demons, the weakest are all in the realm of entering the Dao, and the highest demon is actually the existence of a beheaded corpse.

This demon was very burly, hideous and terrifying, and when he came here, he stopped, and looked around with a pair of cold eyes, and his fierce face was full of surprise.

"Strange, what kind of smell does it seem to have?" There's something strange about this demon.

It had sensed a faint fluctuation and rushed over to check, but found nothing. However, it always felt wrong, as if there was something hidden, and after searching for a long time, it still didn't find it.

"Could it be that I'm thinking too much?" The demon scratched his head for a while, and finally decided that he was thinking too much, so he left with a group of demons and continued his patrol.

After these demons left, a shadow quietly emerged, and continued to comprehend these demon arrays. Lin Yi was secretly surprised, there were not only a large number of demons here, but also very powerful, and there were many demons in the corpse slashing realm.

Soon. Lin Yi comprehended the demon array here. The whole person suddenly merged into the formation. Enter the inside of the Great Array. As soon as he came to the demon array, he immediately felt that the world had changed, as if he had entered a strange world.

All around, there was a strong demonic aura, fierce and boiling, and there was a strong crisis in the air. There are many of these demon arrays, and some of them are black and steaming, and the demon wind is bursting. Filled with icy murderous intrigue.

And in some demon arrays, the flames are surging, and the demon clouds are rolling, as if entering a demon world. And the lethality of these arrays is very great, Lin Yi has to be careful, but after comprehending the core of the demon array, he is naturally not afraid of these things.

He was like a ghost, walking in this powerful demon array, quietly sneaking towards the inner core. He didn't alarm any of the demon arrays, and shuttled all the way. No demons sensed that anyone had invaded here.

Soon, Lin Yi passed through the heavy array. Enter the heart of the Black Dunes. However, as soon as he arrived here, he immediately hid and could not move, and his heart was secretly awe-struck, staring at a huge black cavern in front of him.

In front of this cave, there are four powerful demons guarding it, motionless, full of vigilance. These four demons are all demons with beheaded bodies, and they are very powerful, although they are not Lin Yi's opponents.

However, if he wanted not to alarm these demons into the cave, it would be very difficult. On both sides of this cave, there are two powerful demons, and it is really difficult not to alarm them to enter.

"How do you get in?"

Lin Yi secretly thought about a way, and was not in a hurry, but quietly hid here. He was thinking about a way, but after a long time, he still didn't come up with any good way, no matter what, it would alarm the four demons.

He didn't want to cause trouble, thinking that there were several great heavenly demons in the ore vein, and even a more mysterious and powerful existence, he didn't dare to act rashly.

Most of the day passed, and these demons still hadn't moved, not even the slightest movement. The four demons emitted their own demon god consciousness and shrouded the entrance of the cave, and it was difficult for Lin Yi to think about it.

He was a little anxious to wait, thinking about whether to directly risk pulling the four demons into the inner world to suppress them directly, which would be extremely dangerous, and might even ignite all the demons.

Just as he was about to act and didn't want to wait, there was a fluctuation in a demon array in the distance, which made him hide immediately and watch quietly.

Soon, several figures walked out of the demon array, and four more powerful demons came, as powerful as the demons guarding the entrance of the ore vein, which attracted his attention.

"A few of you are finally here, hurry up and change your guard, Lao Tzu still has to find a few goblins to be happy." At the entrance of the cave, a demon's eyes lit up and he shouted directly.

At this time, the four major demons guarding saw the arrival of these four guards, and the demon god's mind instantly dissipated and withdrew. Moreover, the four of them didn't wait for the four demon demons to arrive, they flew up directly and went out towards the formation.

The four demons who had just arrived shook their heads and ignored them, but they didn't notice that at the moment when the four demons left, a breeze entered the cave and disappeared.

Lin Yi seized the opportunity and entered the cave directly, and as soon as he entered, he suddenly felt a strange aura on his face. He was secretly surprised, and from this strange aura, he sensed a lot of powerful aura oppression.

There are even some strange auras, which feel that they can erode the primordial spirit and arouse his vigilance.

The cave is very large, all the way to the ground, I don't know how long, anyway, I flew at Lin Yi's speed for an hour and still didn't see the end, and the dark cave was filled with a strange aura.

Ahead, three forks in the road appeared in front of him, Lin Yi stayed for a while, and directly chose a road on the left. He sensed a powerful fluctuation from inside, and guessed that there was a demon here, which quickly confirmed his guess.

"Hurry up, get rid of these bugs, adults are still waiting for us."

As soon as Lin Yi approached, he immediately heard such a sentence coming, secretly vigilant, carefully hidden, and approached the past. He found that it was an incomparably wide place, as if it were a huge space formed by nature.

What caught my eye was a group of powerful demons, cleaning up the corpses all over the ground.

These demons were all embarrassed, with some injuries on their bodies, and even many demon corpses were lying here, in stark contrast to the huge insects all over the ground.

These bugs are huge, with black bodies and hideous appearances, and they feel like a terrifying thing. Lin Yi was curious, these demons seemed to have encountered insect attacks, which was strange.

"Hurry up, come with me, a few adults are still waiting." The group of demons moved again, rushing into the depths. (To be continued.) )
