A few days later, in a dense forest, a roar of earth-shaking demon beasts suddenly sounded, the sound resounded through the heavens and the earth, and when they heard this voice, the faces of the four people changed slightly.

In the past few days, the four of them have been groping and searching along this area, but they have not found the slightest abnormality.

The only thing that makes people feel strange is that they can often hear the roar of the demon beast, as if the demon beast is in a rally.

And the source of the roars of these demon beasts was some distance away from the four of them, and it should be located in the depths of the Tempering Mountain Range. Every time they heard the roars of these demon beasts, Chang Le and the four couldn't help but feel terrified. There is no doubt that once Chang Le and the others are discovered by this group of demon beasts, the consequences will be absolutely unimaginable.

After searching this area for several more days, the four of them finally lost their breath and wanted to go deeper into the Lilian Mountain Range to investigate. After all, they had been in this area for a few days, and if there was really something wrong with this place, then Chang Le and the others must have found it.

And after searching here for days, they still haven't found anything strange about this area, so there is nothing wrong here.

Chang Le and the others continue to move forward!

However, if you go inside, the mountain range is even deeper, and the demon beasts that infest are at least fifth-level low-level demon beasts, which are not something that the martial artists of the Tongmai Realm can deal with. Chen Yifeng hesitated slightly, and said, "Why don't we go and find out the reason for the monster's roar during this time?"

Generally speaking, unless there is a strong enemy attacking, or other demon beasts appear in the territory, some demon beasts will let out a roar to warn other demon beasts and warriors, but other than that, demon beasts have no important reason, and they will not scream for no reason. And at this moment, Chang Le and the others searched in this area for several days, and almost every day, they could hear pieces of demon beasts roaring, the sound shook the heavens and the earth, and the number was terrifying.

Situ Xin pondered for a moment, during this time they found that the only thing that was strange was the roar of these demon beasts, and it didn't hurt to investigate. But those demon beasts are powerful, and they need to be fully prepared!

"Chang Le, Yang Fan, what are your opinions?" Situ Xin opened his mouth to ask Chang Le and Yang Fan, after all, the four of them are a group, and it is necessary to ask for the opinions of others before making a decision.

"I'm okay with that. "Since the failure of discussing with Chang Le to buy red spirit flowers, Yang Fan has been silent during this time, except for one or two words when killing demon beasts and picking spirit grass, he has not said a word at all at other times.

Situ Xin turned his head to look at Chang Le again, and Chang Le shook his head slightly, indicating that he had no opinion.

Seeing this, Situ Xin immediately said, "Okay, since everyone has no opinion, then let's go and find out the cause of the roar of those demon beasts."

But speak in advance, those demon beasts are extremely powerful, and I am afraid that they are at least a fifth-level low-level, so everyone must suppress their breath and must not be discovered by those demon beasts!"

"Hmm!" the three of them nodded, and muttered......

Immediately, the four of them each performed their own body techniques, turned into four human shadows, and headed straight towards the depths of the Lilian Mountain Range. Bypassing a dense forest, the four of them lowered their walking speed and slowed down for about half a day, and the four finally stopped.

In front of them was a vast valley, surrounded by a large number of towering trees, and it was impossible to see what was inside. They couldn't see what was in the valley, but the four of Chang Le could clearly hear the roars of these demon beasts, which came from the valley.

Before, they were far away and couldn't hear very clearly, but now they were not far from the source of the sound, and the four of them could suddenly hear the roars of these demon beasts clearly. There seemed to be some tremor and fear in the voices...... Excited!

Soon, however, the voices turned from excitement and fear to a miserable roar, which faded into silence and eventually vanished. Hearing this strange voice, Chang Le and the four couldn't help but glance at each other, and there was a strange look in their eyes.

"Be careful, everyone!"

"Let's go. ”

Situ Xin said two words in a row, and then suppressed the breath on her body to the minimum, and walked slowly towards the valley without being happy or slow. Chang Le and the three of them also suppressed their aura to the lowest, followed behind Situ Xin, and moved towards the valley little by little. However, Lin Chen and the four of them didn't walk for long, and suddenly, a burst of demon beast roars sounded from the left and right of the four of them.

"Roaring ......" several demon beasts with burly bodies and extremely powerful breath suddenly rushed out of a dense forest outside the valley and went straight to the valley. And the place where these demon beasts are going to pass is not far from the four of them, and it is easy to be discovered!

"It's actually a fifth-level demon beast!" The faces of the four people changed, and Situ Xinjiao shouted: "Squat down!"

As she spoke, she fell down and squatted into the bushes, where the bushes were several meters high, and the human warriors squatted in them, as long as they didn't make a sound and reveal their breath, under normal circumstances, it would be difficult for the demon beasts to spot.

Chang Le reacted quickly, and almost at the same time as Situ Xin squatted, he also squatted into the bushes.

Yang Fan and Chen Yifeng were slightly stunned, and then a look of fear flashed on their faces, and they also quickly squatted down, suppressing the aura on their bodies to the extreme.

WhewW...... Click...... A gust of wind swept over the heads of Lin Chen and the four of them, and several black shadows rushed past Chang Le and the four of them in the blink of an eye, and the huge body of the demon beast even collapsed many towering trees, making a clicking sound.

Chang Le and the others only felt their scalps tingling, and a chill was rising from the bottom of the center, until these fifth-level demon beasts disappeared into the dense forest, and the four of them breathed a sigh of relief.

"It's dangerous. ”

"There are a lot of fifth-level demon beasts, what are these demon beasts doing, the few fifth-level demon beasts just now, as if they were scrambling, for fear of entering the valley one step later than other demon beasts. Could it be that there is something in the valley that makes these demon beasts extremely important?"

They glanced at each other, and their eyes showed curiosity, what was in the valley, which made the demon beasts let out a continuous roar, and even the demon beasts from other places were also attracted to it.

"Don't guess, let's go in and see. Situ Xin said a word, continued to suppress the breath on his body, and walked towards the valley. After several fifth-level demon beasts that suddenly rushed out just now, this time, the four of them acted more cautiously and vigilantly, for fear that several demon beasts would suddenly rush out of somewhere and find their figures.

You must know that once the four of them are discovered, even if there is only one fifth-level demon beast, it is enough to make the four of Changle uncomfortable, not to mention that there is obviously more than one fifth-level demon beast in the valley.

The four of them slowed down and cautiously walked towards the valley, spending most of the day, stopping and stopping, and finally came to the middle of the valley.

"Whew!"

"Roar!"

"Silk ......"

The low roars of various demon beasts came, which were extremely clear, and the four of them carefully squatted under a big tree and looked towards the center of the valley. However, at this glance, they couldn't help but gasp: "Hey, there are so many demon beasts!"

At a glance, the center of the valley is covered with dense and powerful breath, all kinds of demon beasts, pythons, snakes, wolves, tigers, eagles, etc., their number is at least hundreds, and it is like a gathering of demon beasts. What's more, these demon beasts gathered here, and they didn't fight each other, but turned their backs to Changle and the four of them with anxious expressions, looking ahead, as if there was something in front of them that was extremely important to them.

These demon beasts were all focused on the front, but no one noticed that the four Changle suddenly appeared behind them.

"What's in there?" The four of them glanced at each other, it was absolutely unusual for these demon beasts to gather here, there must be something inside!

"Go up the tree!" With a low shout, Chang Le's legs were slightly forced, and he jumped onto a big tree with very light movements, Situ Xin, Yang Fan and Chen Yifeng also jumped up, each jumping onto a big tree. The line of sight on the big tree was even broader, and when I looked at it, I saw that in front of many demon beasts, there was an extremely black mist.

"Black Mist?"

"A black fog?!"

"Black Mist, what is this?"

"Could it be that these demon beasts are roaring because of this black mist?"

The four of them were a little puzzled, with a confused look on their faces.

How can there be black fog here?

And is it because of this black fog that these demon beasts are gathered here?

But why, the voice of the demon beast that the four people heard before was excited, miserable and miserable?

Regarding this black fog, all kinds of questions appeared in the minds of the four people, and they couldn't see what the reason was.

At this moment, a fifth-level low-level demon beast with a body like a wolf suddenly roared, and it actually jumped out of the group of demon beasts, and entered the black mist in the blink of an eye. Almost as soon as this fifth-level low-level demon beast entered it, the roar of this demon beast came from the black mist, and its voice trembled with a hint of fear.

Chang Le's eyes narrowed, and through the black mist, he could faintly see the figure of the fifth-level low-level demon beast.

I saw that this demon beast was constantly rolling in the black mist, and streams of blood flowed out of its body, and there were screams in its mouth, which was terrifying. After a while, the sound stopped, and the fifth-level low-level demon beast was lying on the ground, already without breath, and died on the spot.

"Shhh Seeing this, Chang Le couldn't help but gasp, could the black mist be poisonous?

The fifth-level low-level demon beast entered, and it only took a moment for it to die. But if the black mist is poisonous, why are so many demon beasts still gathering here, coveting this black mist?

Situ Xin on the side said in a low voice: "Let's wait here for a few days and see the situation first." ”

In the faint sense, the four of them all felt that the beast tide that had occurred in Yang City before was related to this black fog.

However, the specific relationship between the two, the four have not yet figured it out. After paying attention, the four of them immediately suppressed the aura on their bodies to a minimum, each squatted on a big tree, blocked their bodies with dense branches and leaves, and then observed the black mist not far away.

The black fog is not big, only about 1,000 square meters, and around the black fog, there are hundreds of fourth- and fifth-level demon beasts surrounded, one by one the demon beasts are greedily looking at the black fog, wanting to rush in, but they seem to be a little afraid of the black fog, so they hesitate outside, and they keep roaring in their mouths, walking back and forth, restless.

Chang Le's eyes narrowed, and he looked at the demon beast silently, that demon beast was a fifth-level low-level giant python named Lingmang, its body was extremely large, and it was an extremely powerful one of the fifth-level low-level demon beasts. Seeing Ling Mang rushing into the black mist, many demon beasts around the black mist suddenly became even more anxious, and let out a low roar from their mouths one by one, wanting to follow the Ling Mang into the black mist, but they seemed to be a little afraid of the black mist and did not dare to move forward.

At this moment, a fourth-level top-tier demon beast roared, jumped forward, and jumped into the black mist in front of him.

And as this fourth-level top-level demon beast entered, the demon beasts around the black mist suddenly roared one by one, looking crazy, and they actually followed the demon beast and also jumped into the black mist. In an instant, except for more than a dozen demon beasts that were afraid of the black mist and did not dare to move forward, the rest of the demon beasts all rushed into the black mist.

"What the hell is going on?"

Chen Yifeng looked at the many demon beasts that jumped into the black fog with some horror, what was there in this black fog that made these demon beasts so crazy.

Chang Le's expression was solemn, and he looked at the black mist without blinking.

His soul power was strong, and his senses were extremely keen, but even so, he could only vaguely see those demon beasts in the black mist, as for Situ Xin, Yang Fan and Chen Yifeng, they could only see a vague black shadow.

"Roar ......" As these demon beasts jumped into the black mist, in the blink of an eye, there were many roars of demon beasts inside, Chang Le could faintly see that many demon beasts were rolling wildly in the black mist, as if they were being bombarded extremely strongly, and they were in great pain. Even the Lingmang who entered the black mist first rolled on the ground, stirring the black mist indiscriminately, which looked extremely strange.

"What the hell is the black mist?"

"Entering the black mist, even a fifth-level demon beast can't withstand it. Situ Xin's expression was solemn. The powerful fifth-level low-level demon beast is almost equivalent to the early stage martial artist of the Blood Refining Realm, but even the early stage martial artist of the Blood Refining Realm has not been able to resist the black mist, so the latter is inevitably a little too terrifying. No one spoke, just staring at the rolling black fog without blinking.

The black mist was stirred up by many demon beasts, but it didn't even emit a single thing, as if there was a barrier that shrouded them all and couldn't be emitted. It didn't take long for the frequency of the black mist being stirred to decrease, and the roars of many demon beasts in the black mist also became deeper and lower at this moment, and finally all the demon beasts fell to the ground, and they didn't know how to die.

"They're all dead?"

Chen Yifeng's face was gloomy for a moment and ugly for a moment.

The aggressiveness of that black mist was really terrifying, and hundreds of fifth-level low-level demon beasts were all killed in just a few breaths. But at this moment, Chang Le's eyes narrowed suddenly, but he saw that in the black fog, there was a faint black shadow moving, maybe the black shadow was too deep into the black fog, and he didn't see what kind of demon beast it was.

"One of them didn't die. At this time, Chang Le slowly spoke.

"What?" Situ Xin was shocked in his heart, so many demon beasts were dead, and there were still some who were not dead?

However, what surprised Situ Xin even more was that Chang Le could detect the demon beasts that were not dead in them, that is to say, the situation that could be seen was much more detailed and clear than what the three of them had seen. Yang Fan's eyes narrowed, and he glanced at Chang Le deeply, and his face did not change in the slightest.

"Are you sure you saw a demon beast that didn't die?" asked Situ Xin with a solemn expression.

Chang Le nodded and said, "There is indeed a black shadow, but that demon beast is too deep into the black mist, and I don't see what kind of demon beast it is!"
