Using the aura to fight against this strange poisonous gas was indeed an idea to protect itself, but it was not a decision that seemed appropriate at this time.

The purple-clothed man's attention seemed to be focused on the barrier in front of him, but he was not necessarily at this time also raised his own perception to the extreme. This confrontation was obviously not an easy thing for him, but at the same time it made him more vigilant than ever.

Lu Xingyao raised her eyes, and the next moment she didn't hesitate to let herself climb the rock wall above her head as fast as she could.

This spreading aura is obviously not a normal state, showing not the light state of ordinary gas, but a heavier and more condensed, sinking in the lower state, in her light action of letting herself cling to the cave on the top like a gecko, the purple-black aura that quietly spreads over, rubbing a trail on the ground, and then disappearing into the distance.

At this time, the confrontation between the man in purple and this defensive formation seemed to have come to an end.

Lu Xingyao couldn't see the expression on his face, and could only see from his slightly trembling back that he was not feeling good at this time, and with a slightly raised gaze, the formation in front of him was more and more clearly presented in front of her.

This formation has never appeared in Changning's memory, and there is not even any kind of text or symbol that can be queried in his or Lu Xingyao's memory, and this somewhat strange symbol has any similarity, in some positions, this symbol looks like a child's casual smearing, and in other places, it seems to have some kind of special law, at least when her eyes look over, there is an inexplicable burning sensation.

She struggled to retract her somewhat irrepressible curiosity and turned her gaze to places that didn't affect her.

The aftermath of this diffuse aura shock does not mean that this confrontation has come to an end.

His fingers that were dotted on the formation suddenly appeared one after another cracks along the lines, and these suddenly cracked lines only made him let out a somewhat suppressed muffled sound, and then he saw that the blood stains oozing from the wound on the finger did not fall normally under the action of gravity, but surged towards the direction of the fingertip like some traction.

Between the spread of this blood, the characters on the formation that made people feel palpitations seemed to have suddenly received some kind of blow, and the original blocking power between the spiritual qi also dropped by a level.

The finger, which provided blood and served as a spiritual channel, slowly faded from the blood at this time, and looked a bit white like a dead man's finger.

Fortunately, the most dangerous time between this broken formation was obviously over, and he spit out a few syllables that sounded a little vague from his mouth, and then the spiritual power injected was great at this moment, directly devouring most of the entire formation in a whale swallowing attitude. The formation that appeared in the air made a sound similar to the breaking of parts, and the formation trembled and disappeared into the air.

He didn't cast any concerned gaze at Liu Mu, who was already in the battle between these two parties, and was impregnated by the aura that didn't look like a good thing, with pieces of silver threads appearing on his sideburns, and a cold color on his face, but walked straight forward when the formation was broken.

As the formation disappeared, what was revealed in front of them was no longer a cramped aisle similar to where they were at this time, but a prison.

The reason for this is that the newly emerged cavern, which at first glance looks quite spacious, is littered with broken chains, some of which are still partially fixed to the rock wall, and some of which are scattered directly on the ground in a broken state. Lu Xingyao returned to the posture of standing on the ground from the state of lying on the top surface, leaning into the depression of the stone wall at this entrance, the advantage of being young is that although the depression area is not large, it is enough for her to take a look at the situation in this stone cave while accommodating her.

The ground was full of marks of something scratching, and it was even more obvious on the stone wall, the marks of something scratching through its claws.

Lu Xingyao, who had seen the three-legged black dragon before, felt that there was almost no second possibility, although in this illusion, the state of the three-legged black dragon's imprisonment was not presented in the way of this stone cave, but it did not prevent her from making this guess that seemed the most reliable at the moment.

The materials from which these chains are made are bound to be not simple.

The man in purple did not continue to make any moves such as opening the formation, but directly bent down and picked up a chain from the ground.

In this bending motion, she seemed to vaguely see something falling out from between his collar, it seemed to be a pendant, and the lines that flashed on this wooden pendant could not be fully seen by her eyesight, but from the outline, there was a faint sense of familiarity.

He rubbed the chain he picked up twice on his hand, and then the obviously alienated aura invaded the chain directly, and the collision of the two made each section of the chain make a sound due to the vibration and collision.

Obviously, the chains that can be used for captivity must have something unique, at least under the erosion of such a special aura, it still maintains its original structure.

Lu Xingyao's eyes lit up.

Although he inherited a lot of things from Xiao Ling's collection, but the material is this kind of thing, for her who wants to cultivate now without cultivation, and she has no spirit stones, she really won't dislike it no matter how much, and obviously after he found out that his aura could not damage this chain, his face showed a little deep thought, and after a while, he threw the chain on the ground with a lack of interest.

After doing this, he walked to a corner of the cave.

But there's no hidden entrance here.

He approached the scratches on the ground, and there must have been something between them that caught his attention, but he couldn't see them from her angle, only that he was tapping his fingers on the ground, as if he were dipping into something hidden in the crevices.

Then he looked up at the top again, it looked like it had been smashed into several pieces and then put back together, but between these gaps, the water on the top did not seep down, but when he looked at the gaps, the black that wandered in the gaps made people feel a kind of unwarranted fear.

Before Lu Xingyao could watch his next move, he instinctively felt a sense of crisis.

A black shadow as fast as the wind rushed from the direction from which she came, and the place where she was hiding was the place, and she was forced to jump directly into the stone cave on tiptoe, and had a real meeting with the two people in the cave.
