Feel the strange movement around you. When the two of them slowly opened their eyes, all the chaotic scenery around them completely disappeared at this moment.

The psychic illusion reverted to nothingness and darkness again. However, it was slightly different from just now, at the end of the line of sight of the two, between the endless nothingness, there was a faint glimmer of starlight, which was unusually clear and conspicuous.

"You can go, the poison has been expelled, the illusion has been cracked, and the exit from the poison domain will naturally open. Haixin's blue eyes swept over the starlight, and she looked at Qiao Yudao with a smile.

"Can you go out and find the Charm Moon Water?" Knowing that he was able to leave the Poison Domain, Qiao Yu couldn't help but feel a little happy in his heart. After all, crossing the difficult hurdle of the Poison Domain, and being away from the Charm Moon Water, which was enough to greatly increase cultivation, was equivalent to a big step forward.

However, hearing Qiao Yu mention "Charm Moon Water", Hai Xinlan couldn't help but flash a trace of hesitation in her heart. On his face, he smiled angrily and said, "Let's go out first." ”

"Again, I'm overexcited. Qiao Yu smiled awkwardly, and then immediately ran towards the ray of light excitedly. Seeing this, Hai Xinlan couldn't help but shake her head, and followed one after another.

As the distance from the stars gets closer and closer. The volume of the starlight also gradually increased in the sight of the two. In the end, it completely turned into a huge circle of light. There was a blinding light in it, and nothing could be seen.

"The aura fluctuations in this aperture are so strong, shouldn't there be any danger?" Qiao Yu came to the aperture, feeling the strong aura constantly emitted from the aperture, and quickly stopped and frowned and asked.

"Nonsense, this is a passage to connect the space that has been temporarily opened by the Poison Domain, and if there is no aura fluctuation, it will only be a problem. Hearing this, Hai Xinlan glanced at the former, and while shouting in her mouth, she grabbed the former's hand and quickly rushed towards the aperture.

Just the next moment when the two of them had just submerged into the aperture. The entire aperture immediately began to shrink and shrink, and finally disappeared into nothingness.

"Fortunately, it was timely, otherwise we probably wouldn't have been able to get through. Looking at the disappearing aperture passage behind him, Haixin Lanyu patted his chest with his hand.

"It's such an exaggeration, the passage is gone, and it won't be long before it opens again. Qiao Yu muttered.

"Ignorance!" Hai Xinlan shook off the former's hand, and then her beautiful eyes began to sweep around, and muttered: "This kind of passage opening requires a huge amount of energy, we have cracked the Poison Domain, and the opportunity to open the passage in exchange is only enough to open it once." If you lose this opportunity and want to open it again, you must at least need to cultivate above the Yuan Infant Stage. ”

"How did you listen to you, this poisonous domain seems to be a space formation specially used to connect this area. When Qiao Yu heard this, he couldn't help but say suspiciously. This situation was very similar to the spatial formation he had read about in the immortal classics.

The so-called "space-like" formation is to connect two teleportation points with two spatial arrays. These two waypoints are equivalent to two wormholes. The Monk can travel between the two dimensions at will by connecting the two waypoints.

Generally speaking, teleportation through this spatial formation will greatly shorten the distance in the wormhole space. In ancient times, forces with a little bit of capital would build this kind of space formation in order to travel long distances.

It's just that this kind of spatial formation has long been lost now, and it only appears in legends.

"You're really right this time, this Poison Domain is actually a naturally formed spatial formation. Don't you feel that the void area just now is very weird? In fact, its principle is very similar to that of the spatial formation. Hai Xinlan smiled.

"Then according to what you say, this area is also a teleportation point for a natural space array?" Qiao Yu asked suspiciously.

"It should be, but if we want to use spiritual power, we will never be able to do it with our cultivation. Later, even if we find the Charm Moon Water, I'm afraid we'll have to think about how to get out of here. Hai Xinlan looked around calmly.

"Seeing that you look so calm, I should have already thought of a way, so I don't have to worry about it. Qiao Yu looked at the expression on the former's face and said in a light tone.

However, it did not wait to observe the situation around him. Hai Xinlan suddenly grabbed his hand, and then quickly ran away in a certain direction.

The area is still an underground cavern. It's just that it is obviously very dim, and there is only a little fluorescent jade around. And there is almost no poison gas here. But almost everything around them, including the rocks and the waterholes on the ground, was a deep black color, and it seemed as if it contained a strong poison.

Along the way, Qiao Yu was dragged forward by Hai Xinlan. In this dimly lit area, a pillar of incense was rushed. The two of them finally came to a stop when they came to a brighter area.

"Strange, why are there so many candles around here?" It wasn't until he stopped and Qiao Yu looked around carefully that he couldn't help but look suspicious.

I saw that this was a pitch-black cave full of strange rocks. Except for a small amount of water and rocks, there is little to be seen in the cave. The entire cave is surrounded by a blue flame that hangs on the surrounding stone walls like a candle flame.

"Are you a pig, what kind of candle flame is this, this is a green phosphorus fire. When Hai Xinlan heard this, her face immediately turned pale, and she muttered angrily.

"Oh, it turned out to be green phosphorus fire. Qiao Yu nodded slightly, and after a closer look, these flames were really the green phosphorus fires recorded in the immortal classics. This flame is naturally occurring and does not possess aura, but it can burn almost all the time as long as the environment allows.

There is a chance that this kind of flame will form in a dark and gloomy area surrounded by humidity, and there is a large amount of poisonous gas in the surrounding rocky water. However, most of the fires are still found in swampy areas.

"Miss Ben's guess is indeed correct, the Charm Moon Water must be around here. Haixin's blue eyes swept away by the green phosphorus fire around her, and she said with a happy face.

"What did you guess again?" Qiao Yu asked slightly.

"When I first came to this area, I found some strange traces on the ground, and following these traces to find here, I found this large amount of green phosphorus fire. If Miss Ben's prediction is correct, this place should be occupied by a very powerful poisonous beast, and this poisonous beast is probably also guarding the Charm Moon Water. Hai Xinlan explained lightly.

"It's a poisonous beast again!What is it this time?" Qiao Yu couldn't help but look bitter when he heard this. Along the way, a lot of poisonous beasts have really been encountered. And listening to the tone of the former, it seems that the person I met this time is still a powerful character.

Just find a water that may kill you after drinking it, but you have to face this large pile of life-threatening poisons first. This trip was really bumpy enough. If the result is successful, it is okay to drink the moon water. If he can't succeed, then I'm afraid he will die blindly.

"Don't ask so much, follow me. Hai Xinlan didn't look like she had anything to explain at all, and after carefully observing the surroundings for a while, she took Qiao Yu's hand again and went deeper into the cave.

This time, it didn't take long to run in this dark and dead cavern. The two paused for a moment in front of a dark cave. When Hai Xinlan's beautiful eyes swept the ground, as if she had determined something, she pulled Qiao Yu into the dark cave.

After traversing the small cavern, the two re-entered a spacious cavern.

Only, unlike Fang Cai, this cave is not silent. It was surrounded by the clear and audible sound of running water, and there was a slight cyan poisonous gas that emitted a glowing green glow.

Under the entire cave, four huge black stone pillars can be seen standing on the top of the cave. Although these four stone pillars are black throughout, they emit a bright white light, which completely illuminates the entire moving cave.

And under the four stone pillars, there are four circular platforms with a diameter of one zhang long. Underneath the platform are strange pools of deep green. There are four waterholes, separated by a cross-shaped passage.

It looks like an ancient underground palace, and no matter how you look at it, you can feel that these are not natural formations, but very man-made.

"Look there!" Hai Xinlan's expression was extremely excited after entering this cave and seeing the cyan poisonous gas surrounding her and the four cyan pools. Hurriedly pointed to the distance in front of him in the air, and appealed to Qiao Yu.

Hearing this, Qiao Yu immediately looked at the place where her jade hand was pointing. I saw that about 20 zhang away in the distance, on the mountain wall at the end of this cave. A huge square hole is clearly visible. Inside the hole, there are several black stalactites hanging upside down from top to bottom.

Directly below these stalactites, there is a faint shimmer of light blue. The brilliance reflected in the luster, reflected on the stone wall above, is like a sprinkled star, swaying slightly.

"That...... Could it be the Charm Moon Water?" Qiao Yu looked at the flickering luster, as if it was reflected in the water waves, and he instantly thought of something, and immediately exclaimed.

"That's right, it's indeed the Moon Water, and it looks like there's quite a bit of it. Hai Xinlan nodded and smiled. However, in his heart, there was a faint sense of tension that had never been seen before. The source of this tension is also her inner struggle.

"Then what are we waiting for, hurry up and get it!" Qiao Yu said, he couldn't help the excitement in his heart, and wanted to rush over.

"Slow!" Hai Xinlan hurriedly shouted when she saw this, and grabbed the former's arm fiercely. Before the former was full of doubts and wanted to ask, he preemptively said, "Don't you know that there will be spirit beasts guarding all this precious treasure?"

Hearing this, Qiao Yu calmed down and thought about it carefully, Hai Xinlan had indeed mentioned the matter of being guarded by poisonous beasts just now. Immediately, his face sank, and he asked, "Since that's the case, what should we do?"

"Let's see if Miss Ben's guess is correct. Hai Xinlan said, just raised her hand and swept it, and a water wave flew out of her sleeves and swept towards the poisonous stalactites on the wall in the distance.

Seeing the former's move, Qiao Yu couldn't help but be taken aback. However, the next scene couldn't help but choke up and gasp.

I saw that the water wave was about to approach the moment of the poisonous stalactite. The cyan pool, which was originally silent and waveless, suddenly erupted into a column of water, and a cyan poisonous beast with a body like a huge caterpillar rushed towards the water wave with lightning speed.

A sharp black stinger was evident on the top of the head of this fat, worm-like poisonous beast. The stinger also had some cyan venom sticking to it.

In the blink of an eye, the stinger had pierced the wave of water. The entire wave of water collapsed in an instant.

"Sure enough, it's the Azure Four-headed Worm. Seeing this, Hai Xinlan couldn't help but look calm and appealed.
