Outside the activity room, at the end of the corridor on the right, the staircase on the sixth floor was filled with black and gray fog, and the concentration of erosion fog here was significantly higher than in other places.

On the handrail of the staircase, the shadows created by the black and gray mist distorted, and something seemed to wriggle inside, slowly changing shape.

Such a scene, if Shan Yan and the others were here, they would not notice it at all, and the visibility of the low-level Yao Shi here is probably similar to that of the blind man.

Even Jian Song, who was an 8-star Yaoshi, hadn't noticed the movement on the stairs more than ten meters away.

Swish!

Ling Xun's right hand moved, and the Yao Neng knife was already out of its sheath, and the knife flashed and slashed towards Jian Song in front of him.

At the same time, he shouted: "Flash ...... to the right"

Before the words fell, he saw that Jian Song had already moved, and under the protective mask, his breathing rate changed suddenly, like a galloping horse gasping.

Then, Ling Xun's special vision was to see that Jian Song's body flashed and disappeared in place, appearing in the corner of the corridor two meters away.

Is this a mid-level Yao skill, or a high-level Yao skill? Ling Xun's thoughts flashed in his heart, but he didn't have time to think about it.

With a snort, a moth the size of a human head appeared, rushing out of the eroded fog at the staircase, and between the fan-like wings, the black and gray dust fluttered, and even if he was wearing a protective mask, he felt dizzy when he smelled it.

A fully integrated level 2 Moth Eclipse!?

Poof...... the flash of the sword containing Yao energy slashed and cut the giant moth in two.

Ling Xun raised his left hand and slapped it with his palm, and when the palm wind slapped it, he slapped the corpse of the giant moth onto the stairs on the seventh floor.

Boom!

Putting away the knife and standing, Ling Xun looked at the corpse of the giant moth, thinking of the suspected poisonous dust, and the fact that this occasion did not allow it, he finally gave up the idea of collecting the corpse of the moth and selling it for money.

Turning his head, he looked at the corner of the wall, Jian Song, who was very vigilant, and the latter looked at him with some fear.

"Brother Nightblade, how did you find this Demon Eater Moth?" Jian Song asked in surprise.

"Didn't you say it too, what I'm good at is being a little more sensitive, and ......"

After a pause, Ling Xun said again: "On my hunting certificate, I am registered as a 3-star Yaoshi, and my strength is not strong. ”

Jian Song was stunned, then laughed, stood up, resumed his usual leisurely posture, and said, "Yes." Brother Nightblade is right, you and I are both low-level Yao Shi at the 3-star level. ”

The two looked at each other, but they didn't speak, and they understood each other.

Immediately, Jian Song was in front and Ling Xun was behind, and the two walked down the stairs with very light steps.

"Brother Nightblade, if there is anything abnormal, remember to remind me, the entrance to the demon pit is on the fifth floor, and it is easy to attract the attention of the demon beast if the movement is too big, and then it will be troublesome."

Jian Song walked in front and whispered.

Ling Xun bowed slightly, roughly understanding that near the entrance of the Demon Pit, the sensing power of a mid-level Yao Shi and even a high-level Yao Shi was severely limited.

Jian Song's Yao Neng strength is obviously not far from the 9-star Yao Shi, and his induction power far exceeds that of Shan Yan and others.

However, as you step up the stairs to the fifth floor, your sense of power gradually decreases, and every step is taken with caution.

Fifth floor.

The two walked down the stairs, Ling Xun looked up, looked at the "five" on the wall, looked around, and then understood why Jian Song chose to take the stairs.

On the left side of the hallway, there is a collapsed wall, blocking the passage on the left.

However, on the sixth floor, there is not a trace to be seen.

Is the area near the Demon Pit fundamentally different from other places...... Ling Xun thought secretly, vigilant in his heart.

At this time, Jian Song pointed to the left side and said softly: "The entrance of the demon pit is over there......"

Looking in the direction he was pointing, Ling Xun's eyes shrank, and in his special vision, he saw that at the end of the corridor on the left, there was a staircase leading to the bottom.

How could there be a staircase there!?

Ling Xun was a little frightened, even if he didn't know the topography of the Second Yao Neng Academy on the outskirts of the city, judging from the topography of this teaching building alone, there would be no stairs there.

"The entrance to the magic pit is actually between the fourth and fifth floors." Jian Song said affirmatively.

Can you explain why it's between the fourth and fifth floors?

Ling Xun's face was expressionless, but there were one question mark after another in his heart, but he had to maintain the character of the mysterious master Night Blade, and he couldn't open his mouth at will, so as not to reveal his stuffing.

"Let's go." Ling Xun said.

The two of them moved more carefully, still maintaining one after the other, and quietly walked down the staircase that should not have existed.

In the middle of this special staircase, Ling Xun took the measuring instrument and looked at it, and the concentration of the erosion fog here had soared more than three times.

He was very glad that when he bought the equipment, the protective mask was of excellent quality, and the filtration and protection effect was very good, and the inhalation and filtration of the eroded fog only had some symptoms of vertigo.

Of course, if you only rely on a protective mask, you will not stay in such a place for long, which will cause air erosion of the respiratory tract.

At this time, Ling Xun could clearly feel that the heart and other organs were working, and the inhaled corrosive qi was quickly dissolved and was no longer affected.

This is the key to opening the second consciousness, the "smell" of the energy, which not only improves the sensitivity of the energy, but also greatly improves the tolerance to the fog environment.

Not only that, but Ling Xun also sensed another great benefit of being a 3-star Yao Shi with his second Pearl.

"The average 3-star Yaoshi, in such an environment, will definitely not be able to support it for long. Even a 4-star Yao like Shan Yan and them can't last much time here. ”

"However, I don't feel anything, this should be relying on the pearl of knowledge and the benefits of the second consciousness."

At this moment, Ling Xun has enlightenment, and the Yao consciousness opened by relying on the Zhi Zhu should be the same as the Body Bead, and it has reached an extreme.

Therefore, in such an environment, there is not much feeling, and it is not affected by the high concentration of erosion fog here.

On the other hand, Jian Song on the side obviously had some difficulty breathing, although he tried his best to suppress it, his breathing rate was still unstable.

"Can you still hold on? If not, let's go back. Ling Xun said.

Although his tone was calm, in his heart was the support of beating drums and daring to approach the entrance of the demon pit, which was Jian Song's strength close to that of a high-level Yaoshi.

Coupled with his own special abilities and some hole cards, Ling Xun has such confidence.

Now, seeing that Jian Song was even a little unsteady in breathing, Ling Xun naturally retreated, tens of millions of coins are tempting, but he also has to have his life to get it.

"It's fine. Brother Nightblade, wait for me. ”

Jian Song stopped, leaned against the wall next to the stairs, and took out a pill, a round pill that shimmered with a little light.

Lifting the protective mask and throwing the pill into his mouth, Jian Song suddenly relieved, saying that it would only take half a minute, and it would be fine.

Seeing that Jian Song's breathing was fast and steady, Ling Xun relieved himself, and his confidence in this temporary teammate was a little more, with such an unheard of pill, it seemed that the temporary teammate also had a lot of hole cards.

"This night blade, in such a high-concentration eclipse mist, it really doesn't seem to be affected at all!"

Swallowing a special Demon Clearing Pill, Jian Song felt the suffocating sensation in his lungs quickly disappear, and glanced at his silent temporary teammate Night Blade, and a storm set off in his heart.

Before, on the sixth floor, he noticed that the hunting of the Night Blade, in the high-concentration eroded fog environment, had an amazing sense of power, and his strength was suspected to be a mid-level, or even a high-level Yaoshi, which aroused Jian Song's interest.

Thinking about the hunt of Nightblade, it should be a good teammate, and they can explore the medium-sized magic pit here.

Unexpectedly, in the high-concentration eroded fog environment, the sensing power of the Night Blade was far beyond imagination, as if it could clearly see the surrounding scene.

You must know that Jian Song has an extraordinary background, and at the level of middle-level and high-level Yaoshi, he has also seen a lot of Yao Neng people with amazing sensitivity.

However, such an extraordinary sense of induction, Jian Song has never encountered it.

At this moment, the two of them were already near the demon pit, and the protective mask worn by the Nightblade was obviously only a style used by mid-level Yaoshi, but it was not affected by the eclipse fog here at all, and the breathing rate had not changed from beginning to end.

Could it be that the strength of the Night Blade has reached the peak of the 12-star Yao Shi, and it is about to break through to the Yao Neng Division?

Nightblade is about the same age as me, and I'm about to break through to the Dawn Master?

No, it's very likely that Nightblade has mastered the precedent of a legendary breathing method to be able to breathe so freely and unaffected!

……

In Jian Song's mind, speculation flashed one after another, Rao is that he is very clever, he has seen and heard extraordinarily, and he can't figure out what the Night Blade relies on.

For a while, looking at the young man in front of him, Jian Song suddenly felt unfathomable.

"Half a minute? How are you? Ling Xun pinched the seconds and asked.

Hearing this, Jian Song was stunned for a moment, indicating that he was fine.

"Brother Nightblade, let's go down." Jian Song said.

Quietly, the two went down the stairs, and Ling Xun looked around, his eyes slightly condensed.

Around, the layout of the buildings is very different from that of the school building, with a circular passage with two straight passages and classrooms.

It's just that the doors and windows of these classrooms, some of which are upside down, some are crooked, like toys built at random.

The walls are damp and rotten, and the pieces of wall skin are peeling off, revealing the seeping walls, and even some severed limbs and stumps can be seen inside, and the dense black ash mist is permeated, which looks particularly gloomy.

When he arrived here, Jian Song was also visibly nervous, and reminded him of something softly.

"Brother Nightblade, I will try to use the Yao Neng Breathing Technique as little as possible, you have strong sensitivity, I have a very weak induction here, and I am almost blind two or three meters away."

Jian Song said.

Yao Neng Breathing Technique ......, and I can only learn by opening the third Yao Sense, I am just a low-level Yao Shi, and I won't use it, Ling Xun muttered in his heart.

"Also, try not to make a sound, the hearing of the monster is extremely sensitive, if I accidentally bump into it, I won't have time to use the Yao Neng physical skill, it will be bad. The demonic beasts near the medium-sized magic pit are difficult for high-level Yao Shi to compete alone, and it is the safest way to lead them away. ”

"Also, try not to release Yao Neng, the brilliance of Yao Neng is similar to a torch in the dark to a demonic beast."

Jian Song said again.

Ling Xun bowed slightly, pretending to be observing the surroundings, but in fact he listened very carefully.

"Also, around the medium-sized magic pit that has just formed, don't try to destroy these walls, the concentration of erosion fog contained in them is extremely high. Once damaged, it is like detonating a fog bomb, which can easily cause serious erosion injuries. ”

The lethality of this kind of wall should be ineffective against the strengthened hands...... and Ling Xun is secretly dripping, which is another advantage for him.

Lingxun looked at the black-gray wall of this compartment, thought of something, and silently observed the route.

Before Jian Song could say something, Ling Xun suddenly raised his hand to stop Jian Song from continuing to speak, and at the same time, made a "silence" gesture.

Suddenly, Jian Song immediately shut up and stood there, motionless.

Then, Ling Xun stretched out his hand, pulled it aside, and leaned against the corner, the figures of the two of them almost merged with the eclipse fog.

"What's going on?" Jian Song used his eyes to ask his temporary teammates.

Ling Xun didn't speak, he pointed not far away, and said in a very slight voice: "There, it should be the demonic beast you are talking about." ”

What?

Warcraft!?

Jian Song's eyes widened suddenly, and he secretly exclaimed, don't scare me, how could a demonic beast appear here, there is still a little distance from the entrance of the demon pit.

Ling Xun didn't answer, and in his special vision, he saw a monster with a body like a calf and gray and black leather slowly walking from the side of the circular passage.

Winter......

A dull sound made Jian Song immediately hold his breath and not dare to make a sound.
