The so-called spatial illusion is a spatial illusion created by the powerful method of chanting array, in which ordinary monks will produce visual illusions, which can cause confusion at least and life and death at worst.

The only way to break through the restrictions of the spatial illusion is to forcibly break it, but the method of reciting the formation here is extremely powerful, and Wu Wei's current comprehension of the formation cannot be lifted at all.

The spatial illusion formed here looks unusually calm on the surface, and there seems to be no danger, but after experiencing several life and death crises, Wu Wei faintly feels that there seems to be great danger behind this seemingly ordinary.

Just as he was thinking about it, his divine sense inadvertently glanced a hundred zhang in front of him, and suddenly noticed a trace of aura fluctuations in the blue mist.

"Could it be another kind of heaven and earth aura..."After looking closely, he found that a gray gas appeared in the misty blue mist, and this gray gas was just like the chaotic qi seen in the chaotic realm back then, dim and obscure, revealing bursts of desolate chaotic aura.

The speed of the gray gas diffusion is extremely slow, like smoke and dust mixed into the morning mist, it gradually merges with the blue mist, and the whole sea of blue mist suddenly turns gray!

If it weren't for Wu Wei's extreme sensitivity to this kind of gas, he wouldn't have noticed such a strange change at this moment, and he could feel that the gray mist was filled with an extremely dangerous aura.

"There's something wrong with this..."

Wu Wei's eyes flickered, and after looking at the gray mixed mist for a while, he turned around and walked towards the other side to avoid the direction where the gray mist was, although the speed of the gray fog spreading was slow, but the area they covered was extremely wide, almost in a closed circle, slowly shrouded.

Wu Wei ran as he exuded his divine sense to observe the changes in the gray mist, and with the location of the gray mist, he guessed that as long as he passed through the gray mist, he should be able to find the entrance to the next layer at this time.

...

Looking at the three of them again, after passing through the blue mist, they had the experience of coming here for the first time, and they didn't know what method they used, and they soon found the entrance to the next floor, but they didn't notice, or ignored the gray fog that gradually surrounded them.

If you look closely, you will find that the pupils of Qi Kill's two eyes have begun to appear to be eroded by the gray mist, his eyes are full of bloodshots, a cloudy gray gas began to spread around his eyes, his face is becoming more and more pale, and the vitality in his body has actually shown signs of slow passing.

He didn't even notice such a subtle change, he only felt a trace of fatigue all over his body, as if he thought that he had been wandering around in this illusion space for too long, and his physical strength was a little exhausted.

"Oh no, this fog doesn't seem right..."

After walking for about a quarter of an hour, Chi Xiao finally noticed the abnormality of his body, he immediately stopped, raised his hand, and the majestic spiritual power in his body surged out to protect his body, and at the same time, he was horrified in his heart, with his cultivation, he had just felt the abnormality of his body.

"My lord, look at him..."The black-robed man who had always been guarding his side also stopped, and one of the black-robed people pointed to the other person who was behind him, and said in surprise.

I saw that the black-robed man was in a trance for a while, his steps staggered and fell behind, and his face was even more pale, as if he had been forcibly seized by some force, and the whole person showed signs of withering.

Qi Kill glanced back at the black-robed man behind him, as if he suddenly remembered something, his face suddenly changed greatly, and he secretly exhaled, "Curse Qi..."

Immediately, he didn't say a word, he didn't pay attention to the black-robed man who had fainted on the ground, and beckoned the black-robed man who was still awake to gallop away quickly in another direction.

At this time, they were not more than a hundred feet away from the entrance of the next floor, but Qi Kill still resolutely chose to retreat, because he knew deeply the horror of the sudden gray qi.

...

On the other side, Wu Wei avoided the gray mist all the way, and after going around a few times, he found that the gray gas was emitting from the direction of the entrance.

Although Wu Wei has always maintained his caution since he practiced, he is not the kind of person who cowers, and if he wants to pass to the next layer at this time, he must pass through this gray area.

"Wealth is in danger, since you have come here, there is no reason to retreat from the battle..."He pondered for a while, and finally chose to take a risk.

At the moment when he burrowed into the gray mist, he could feel the gray qi slowly enveloping around him from the seven orifices and the pores of his skin, which would be imperceptible if he didn't feel it carefully.

He tried to use his spiritual power to block the invasion of those gray gases, but found that there was no effect, and those gases were like the original chaotic gas, with an irresistible power.

Soon he noticed that the gray gas was slowly scurrying towards his body through the limbs and bones, and the gas was like a spider dragon, wandering around his body, as if looking for something.

Wu Wei looked inside his body in disbelief as he ran quickly, and he soon found that the gray qi had faded out of the pores of his skin after swimming all over his body, and his body did not appear to be abnormal at all.

"What's going on?" Wu Wei had a suspicion in his heart, the danger he guessed had not happened, and his body seemed to be much more comfortable and lighter under the washing of those gray qi.

"Maybe it's too cautious...", although he couldn't figure it out in his heart, he could only give such an explanation, and after a little silence, he sped up and sped away in the direction of the gray mist emitting.

Time passed little by little, and a trace of clarity began to appear in front of the gray gas, and sure enough, as expected, the direction in which those seemingly dangerous gray gases appeared was the entrance to the next layer.

...

On the other side, Chi Xiao and his group of five had just entered the spatial illusion realm at this time, and they were also extremely confused about the strangeness of this place, and soon they also walked into the gray mist where the blue mist and gray gas fused almost unnoticed.

In just a few days, this piece of blue mist like a sea of spatial illusion gradually turned gray and white, as powerful as Chi Xiao and Qi Kill two people could not really resist the erosion of that mysterious force, although they were able to use their spiritual power to temporarily resist the plundering of the gray mist's vitality of the body, but after being in it for too long, they still couldn't get rid of the fate of the body and the fall.

Unless, of course, they were able to hold on to find the entrance to the next tower before their spiritual power was exhausted.

At this moment, Wu Wei stood in front of a cyan light curtain, the light curtain was only about three zhang in range, the fog inside it was dense, the divine light was swirling, and it was full of desolate atmosphere, and soon the illusory light and shadow of a tall tower appeared in the light curtain, and if you carefully identify it, you can quickly determine that it is the tower you saw outside before.
