In the fierce yin wind, Deng An and Yin Cheng Key alternately used the ghost fire to resist the wind. Starting from the resting stone room, they had already walked out of more than 100 zhang, and if they acted alone, they would not be able to do it as easily as they are now, and there was a lot of spiritual power left.

Gradually, at the bottom of the passage in front of the two ghosts, a black "mirror" appeared. Although the gaze of meditation is greatly affected by the yin wind, and it is difficult to see the distance clearly, the ghostly light reflected by the "mirror" has a strong penetrating power, like a bright light in the dark night.

As we get closer, the outline of the "mirror" becomes clear. It is an irregular oval shape, and the overall color is black and bright, which contrasts greatly with the gray of the stone wall.

After Deng An looked at the "mirror", while dividing his energy to condense the ghostly fire, he asked suspiciously: "How sure are you that Daoist friends are sure that it connects to the sea of fog in the valley?"

Yin Cheng said hesitantly: "Five or five! The so-called wealth and strength are sought in danger, but if you continue to walk along the passage, it is you and I who join forces, and it is unlikely that you will go out." ”

Deng An frowned, and did not refute, Yin Chengkey's words are not unreasonable, the passage ahead is still endless, and the wind is getting stronger and stronger, once their spiritual power is exhausted, they are blown away by the yin wind, under this kind of wind, it is impossible to protect themselves.

The only way was to try the suggestion of the Yin Cheng Key, although he had enough mental preparation before leaving, but when it came to the end, he couldn't help but be a little apprehensive.

Previously, Yin Cheng Key revealed that from all the information he had obtained, he had a conclusion that Yin Wind was only a protective barrier on the periphery of Yin Wind Valley, and Yin Wind did not exist in its depths. Back then, Wanyong in the Black Dragon Valley had reached a place called the "Sea of Fog". Of all the information about the Valley of the Yin Winds, this is the only one that has not been recorded. He also believes that as long as he passes through the "Sea of Fog", he should really enter the Yin Wind Valley.

Yin Cheng Key had discovered this "mirror" in several previous attempts. Since the yin wind can blow into this passage, then the sea of fog can also seep into it.

Of all the doubts, the "mirror" is the most likely to connect to the sea of fog.

As if to support the speculation of the Yin Cheng Key, a rock in front of it, unable to withstand the blowing of the Yin Wind, suddenly peeled off from the stone wall, was quickly swept into the Yin Wind, and then slammed into a slightly raised stone wall.

The rock was instantly smashed into countless pieces, except for most of which was re-swept into the yin wind, one or two pieces were blown and crashed into the "realm".

Instead of shattering as expected, the "realm" was like a stone thrown into the water, and after stirring up a ripple, it was smoothed out by the strong wind around it.

When the two ghosts saw this scene, they couldn't help but get excited. This means that behind the "realm", it is really possible to connect to the "sea of fog", and in this extreme environment in the passage, without supplementation, the "mirror" cannot be smooth for a long time.

After having a goal, the two ghosts quickly reached the edge of the "realm". Only then did they discover that this "realm" was actually formed by an almost liquefied mist. However, if you want to make love for the situation inside, it is difficult to do it, because the surface of the fog is compressed very flat by the wind blowing, and unless you penetrate it, the line of sight will reflect back.

Deng An's understanding of the so-called "Sea of Fog" was limited to the introduction of Yin Cheng Key, so he naturally did not dare to risk himself, but Yin Cheng Key did not care about this and took the lead in floating in. Before going down, he first condensed a flame light shield outside the soul body, and according to his speculation, since the ghost fire can resist the yin wind, then the ghost fire must also be able to resist the mist.

"Deng Daoyou, you can come down. Soon after, the voice of the Yin Cheng Key came out of the mist. Listening to the sound, it behaves very normally, and it doesn't look like there is danger inside.

Deng An showed a decisive look on his face and followed him to the "realm".

Since the mist was only nearly liquefied, not a real liquid, it was difficult to hinder his soul, so it was effortless to pass through.

Visually, it is still a black and gray color. Because of the fog, the line of sight here is seriously affected, and only objects within a radius of more than ten zhang can be seen clearly.

At this time, Yin Cheng Key was standing not far away, looking at Deng An with a smile.

"Daoist friends can rest assured, the fog here seems to be different from the fog in the rumored 'Sea of Fog', and it only has a slight corrosive effect on the soul body, presumably it is still far from the real 'Sea of Fog' here, and the reason for the small concentration of the fog, but we can't take it lightly, it's better to follow the previous method, take turns to protect the body with ghostly fire. ”

Hearing this, Deng An slowly put away the ghost fire shield. Sure enough, there was a slight consumption of his soul body immediately, if the distance to the valley was short, this consumption could not be remembered, but if this distance was too long, it would be a rather dangerous process.

Deng An was not careless about this unknown fog, and after trying it, he immediately condensed the ghost fire shield, and this time, he saw the reaction of the fog touching the ghost fire.

On the surface of the ghostly fire, as soon as the mist came into contact, some extremely fine black filaments were released, which made Deng An couldn't help but think of the terrible black filaments he encountered on the road, but it was certain that the black filaments that appeared here were not the same as those encountered on the way. In the temptation just now, he did not feel the slightest change in his emotions.

Seeing Deng An's cautious appearance, Yin Chengkey scratched his head embarrassedly, as if he was ashamed of his carelessness, and then, he also burrowed into the ghost fire shield. Because of Deng An's assistance, he naturally didn't have to worry about being stained with his soul by the ghost.

The two ghosts walked in the fog for less than half an hour, and suddenly their eyes became open, and the stone walls on both sides disappeared.

This indicates that the harm of the mist to the soul body has reached a terrifying level, walking in this environment is completely different from the Yin Wind Passage, where they still have a slight turnaround, but here, the slightest carelessness will be doomed.

Yin Cheng Key's confident expression had long since disappeared, replaced by a look of horror, his gaze retracted from the fierce surging mist outside the Shadow Fire Shield, and said to himself, "This is the Sea of Mist?" However, it was impossible for him to get an answer, because his companion also knew nothing about it.

The fog here is even thicker, and there are grains of liquid suspended everywhere in mid-air, and the sight here is even worse, and the two ghosts can see less than six or seven feet in front of them.

However, neither ghost has any intention of giving up. After exchanging views with each other, they took a few steps back and walked along the stone wall, with a reference, it was not easy to get lost in the fog, and even if there was danger, they could return along the way.

In the place close to the stone wall, the line of sight is also slightly wider, and you can see one or two zhang more than other places, because the temperature of the stone wall is low, the fog here continues to condense into water droplets, falling from the air, they are like walking in the rain, and the consumption of ghost power is larger.

At this time, Deng An discovered a strange phenomenon again. Before entering this open area, the mist came into contact with the black gas formed by the ghostly fire, and drifted outward scattered, but when it arrived here, the black gas formed would be slightly biased in a certain direction. Since this power was still very weak, they couldn't feel it from the Flame Shield.

Thinking of the yin wind, Deng An couldn't help but be alert.

As he moved forward, he became more and more convinced that his guess was correct, because, even through the Flame Shield, he could feel the effect of an external force.

"Did you feel anything?" Deng An slowed down a little and asked the Yin Cheng Key next to him, after all, the other party knew more about Yin Wind Valley than him.

Yin Cheng Key didn't take this to heart, and said casually: "Deng Daoyou refers to those weak forces, we seem to have left the passage, this place is likely to belong to the scope of the sea of fog, there is a flow phenomenon between the fog, it is normal, Daoyou don't need to worry too much." ”

"I'm suspicious. ”

Having said that, Deng An was still uneasy, and always felt that it was too calm here, if it was really a sea of fog, in addition to the corrosive power, there should be something more terrifying.

It didn't take long for the power coming from the mist to become more obvious, it was a suction force for a while, and a thrust for a while, making it difficult for the two ghosts to control the strength, and it was also inconvenient to move.

At this time, even the confident Yin Cheng Key became suspicious: "It's really weird! I'm afraid there is really a more terrible danger in this fog, so let's be careful." ”

As soon as his words fell, Deng An faintly heard a "whine" sound from one side, this sound has a strong sense of rhythm, and under careful identification, it looks like a yin wind whistling, but it is plausible, because the yin wind in the passage is all sounded together.

If it's not a yin wind, what will it be?

Deng An and Yin Cheng Key glanced at each other, and the doubts in their hearts were even worse.

Suddenly, the faces of the two ghosts changed greatly, for after a moment's delay, the voice suddenly increased considerably, and it was coming at them in the direction of the spirit.

The two ghosts almost didn't need to discuss, and immediately retreated along the stone wall, but as soon as they retreated two or three feet, they saw a whirlwind rushing to the sky, galloping from the fog in the distance.

Looking at this whirlwind that I don't know how wide it was, the two ghosts were frightened and almost wanted to fly out of the sky, at least with their current vision, they couldn't see the edge of the whirlwind at all, because of the uneven force, the sound produced by the friction between the whirlwind and the fog was intermittent.

Deng An and Yin Cheng Key's eyes both showed despair, under the whirlwind of such power, they had no possibility of escaping at all. The two ghosts were furious in their hearts, and leaned against the stone wall, Yin Cheng Yin frantically injected spiritual power into the shield of the control, making it stronger, and Deng An followed with another ghost fire shield, putting them under double protection.

Almost before they were ready, the whirlwind was blowing.

Under a violent force, the light flame shield of Deng An and Yin Cheng Key, with little resistance, shattered one after another. They were instantly swept into the whirlwind, and then, under the force of the whirlwind, they were thrown into the distant mist.
