"Boom!"

With Huang Yuchen's loud shout, the formation near the dense black fog was directly ignited and activated, and the nearby Wuhe Array and the Lihuo Array erupted almost at the same time, and the flames that burst out from the Fire Array rushed out more than two feet, and the five-sided barriers of the Wuhe Array also quickly unfolded, directly enveloping the dense fog that had just hit the barrier.

In this area, in addition to an isolated Wuhe Array, there are about seven Fire Separation Arrays, two Fire Armor Arrays and two Fire Spring Arrays, after Huang Yuchen activates the formation, these formations will operate automatically, and there is no need for Huang Yuchen to inject additional energy.

In an instant, in the small space wrapped in the Wuhe Array, the dense black mist and a large number of jets of flames were mixed together, and Huang Yuchen and Lu Zhihui stood in the center of the formation, looking at everything that happened in the regional formation with a nervous expression.

In the middle of the formation, the dense black mist was enveloped in a large amount of flames almost instantly, and during this time, he could hear the sound of something screaming, but this sound was extremely small, and Huang Yuchen couldn't even tell if it was the enemy's scream or his own hallucination.

After a few breaths, the Wuhe array approached the barrier in the direction of the center of the array, and suddenly became pitch black, as if something extremely black was attached to the barrier, no need to think about it, this was naturally a high-level beast surrounded in the middle, looking at the way it was pasted on the barrier, as if it was suffering greatly, and was trying to find a way to get out of the barrier in front of it.

Huang Yuchen frowned, he found that this level was very different from before, mainly reflected in the black mist that suddenly appeared. If this thing is the illusion of a high-level beast, then it is different from the enemies I have seen before, it does not have a fixed form, and it does not have a human form at all. Also, almost all of the enemies encountered before were in pain without incident, whether it was Huang Yuchen burning with the fire array or directly hitting the fire attribute element into the enemy's body, the man in white who fought before had nothing to do with this kind of blow, only the enemy in front of him in his eyes, desperately trying to take the life of Huang Yuchen or Lu Zhihui.

But this black mist was obviously different, judging from the state of its attachment to the barrier, there was a clear curling and twisting in the flames, although the overall form was still a mist, but it was also clearly distinguishable that this mist was suffering greatly.

Huang Yuchen was thinking about it, when a scene suddenly happened in front of him that surprised and even shocked him, only to see that after this black mist struggled along the barrier of the Wuhe Array for a while, a part of the mist actually directly skipped the Wuhe Array and seeped out from the inside of the barrier, as if this thing had passed through a mirror out of thin air, but the mirror was still intact.

"This is ......" Huang Yuchen looked at the scene in front of him in surprise, a little unable to believe his eyes. At this moment, Huang Yuchen was standing in the Wuhe Array, and when he activated the formation, he did not contact the Wuhe Array, that is to say, when Huang Yuchen activated the formation, his energy directly penetrated the barrier and was beaten out, but this is because the energy attribute of the Wuhe Array is the energy of Huang Yuchen itself, and the two are originally of the same origin, so there is such an effect. And now seeing this black mist actually pass through the barrier out of thin air, how can you not make Huang Yuchen arrive in shock.

In just a few breaths, a large cloud of mist had already drilled out of thin air from the formation that was completely scorched by the fire array wrapped in the five-way array, and the original five-way array was still standing there, and the barrier did not show any signs of being destroyed.

Huang Yuchen frowned, after this black mist came out, he lingered in place for a few breaths, as if observing the surrounding situation again, and then determined the location of Huang Yuchen and Lu Zhihui, and the entire mist condensed into a bundle of qi swords again, directly rushing in the direction of the two.

"Damn!" Huang Yuchen's eyes froze, and he once again shot out a ball of fire attribute energy, the speed of the energy was extremely fast, and in the blink of an eye, it fell into a closer layer of formation, almost the same as before, and the formation of the next layer was activated in an instant, and the flames rose into the sky, and the Wuhe array once again wrapped this black mist in it.

"What the hell is going on?" At this moment, Huang Yuchen's heart was a little anxious, he didn't understand the enemy's situation at all, and how to deal with this kind of enemy without a fixed body, Huang Yuchen had no clue at all.

"Don't be in a hurry. At this time, Lu Zhihui's mood was much more indifferent than Huang Yuchen's, but she could hear that her mood had also changed, and she said quickly: "Did you find it, after this black mist came out of the previous formation, it was much smaller than before, and you look at the previous formation." As he spoke, Lu Zhihui pointed directly to the outermost circle of formations, and in the state of this circle of formations being reactivated, the fire array did not release all the energy, and in the entire small formation, there was a sea of fire.

But Huang Yuchen still found a trace of abnormality, near the barrier squeezed out of this black mist, Huang Yuchen clearly saw a lot of black mist, these mist was slowly ignited by the fire array, and then slowly dissipated in the formation. Seeing this scene, Huang Yuchen immediately understood what Lu Zhihui meant.

"It has a way to escape my formation, but it all comes at a price. Huang Yuchen glanced at the formation of the second layer, the black mist had been completely ignited by the fire array, and the kind of roaring sound that he heard before came here, this time Huang Yuchen could be completely sure that this was the scream made by this black mist, but this sound sounded extremely distant, as if it came from another time and space, and it didn't happen in front of him.

"That's right!" Lu Zhihui immediately said: "Although this kind of enemy does not have a fixed body, they can obviously feel pain, unlike the previous enemy, if it wants to approach us through all formations, it will inevitably be seriously injured!"

Before Huang Yuchen could speak, the previous scene reappeared, the black mist that had been ignited was directly attached to the barrier, and then a little black aura seeped out from the outside of the barrier, this time was obviously much faster than before, it was obvious that this black mist had learned how to use the minimum cost to crack the formation in the previous formation.

This black mist is sapient!

Huang Yuchen immediately discovered this, the black mist seeped out little by little, this time it was not a more concentrated location, but the entire barrier was completely covered by the black mist, and the location of the infiltration also covered the entire barrier, and only a small amount of fog penetrated out of each point, but because it covered the entire barrier, the speed of penetration was extremely fast.

This time, Huang Yuchen's reaction was faster, and before these fogs could completely penetrate through, Huang Yuchen immediately activated the third layer of formations, and the reappeared Wuhe Array and the Fire Separation Array directly squeezed the black mist that had not completely penetrated the previous formation between the two barriers, and between the two barriers, Huang Yuchen just arranged a fire armor array to enhance the defense of the Wuhe Array, although the offensive ability of this kind of formation was not strong, but before such an environment, it invisibly increased the attack ability of the fire armor array.

"Boom!"

The flames were ignited again, and the black mist had just passed through the part of the previous formation that was attacked again, and the sound that was several times more terrible than before came again, this voice was clearly heard by Lu Zhihui and Huang Yuchen, but this time the distance was closer, but the sound sounded as if it was farther away, this sound didn't seem to come to their ears, it was more like it came from the bottom of the hearts of the two of them.

Huang Yuchen's initiative this time had a very good effect, after the change of moves, this black mist obviously did not immediately find a way to crack it, just stuck between the two Wuhe arrays, scorched by the steaming flames of the fire armor array, there was no way to immediately penetrate the next layer of barriers, the terrible screams never stopped, this kind of voice that seemed to come from their own hearts, listening to it made both of them have a feeling of palpitations.

"Damn, it doesn't seem to have done any real harm to it at all. Huang Yuchen looked at the black mist struggling painfully between the two barriers, and his brows couldn't help frowning, although this mist also left a lot of mist after passing through the second barrier, and it was completely burned by the fire array, but looking at the state of this mist and the way it struggled, it seemed that it had not been harmed at all.

"We don't know what the enemy is yet, so let's not jump to conclusions. Lu Zhihui hurriedly said to Huang Yuchen: "The enemy that appears this time is much smarter than before, and will make changes according to the current battle situation, and we can only use this way of consumption before we figure out its weakness." ”

Hearing this, Huang Yuchen nodded slightly, at this point, Lu Zhihui is right, this black mist looks like it has not been harmed, but neither of them knows what this black mist represents, nor do they know under what circumstances it will be injured, the current consumption method of using the formation is the most appropriate strategy for the current situation.

Huang Yuchen glanced back at the formation behind him, which also had eight circles, and said in his heart: If this thing is so smart, I will use the formation to consume it, and see if it has more fog or more formations.

As soon as the idea came to mind, the situation changed again.

I saw the black mist squeezed in the middle by the two barriers, originally Cheng dispersed state, only a few breaths later, it seemed to have found a way to crack it, the scattered fog suddenly moved, the whole fog quickly condensed, in the blink of an eye, a condensed darker air mass appeared in the middle of the two barriers, and the next moment, this air mass directly hit the barrier in front of him.

"Click!" There was a crisp sound, and in Huang Yuchen's shocked gaze, this condensed black mist actually directly knocked out a fine crack in the barrier of the Wuhe Array
