Passing through a hazy black mist, the Black Dragon Pool appeared in front of Li Xuan and the girl.

A pool of water that doesn't seem to be too big, but if you look up, you can't see the end anyway.

The water is black and meandering, like a black dragon extending forward.

The two sides of the "black dragon" are full of greenery.

It seemed to be full of vitality, but the keen Li Xuan had already noticed that there was not even a single bit of vitality in this Black Dragon Pool.

The mist outside the Black Dragon Pond seems to have the function of isolation, isolating all the already thin aura on the earth.

Here, it's a separate world!

Here, there is no aura in the world!

The girl seemed to be a little nervous, and she clutched the corner of Li Xuan's clothes tightly, as if she didn't want him to continue to move forward.

She looked back at where they had come, to see how far they had come.

However, when she turned around, the girl was shocked!

The hazy mist was gone, and their path was gone...... What she could see was exactly the same as the one in front of her, and she didn't know how far the Black Dragon Pond water had spread!

"Hey, hey, our way of coming from—why did we disappear?" the girl shuddered, patting Li Xuan with an extremely nervous expression, and asked.

Hearing this, Li Xuan also glanced back behind him.

"I've told you that the dead can't get in, and the living can't get out. Li Xuan was not surprised, he also said with a wicked smile.

"Huh, what should I do then?" The girl thought that Li Xuan was joking at the time, but it was not until this moment that she realized that Li Xuan's words did not even have the slightest element of laughter.

Here, you really can't get out!

"I don't believe it, there is still a place where I can't get out, maybe the end of this Black Dragon Pond is the way out!" Seeing Li Xuan's solemn expression, the girl said viciously.

"You can try to make it to the end. Li Xuan said with an evil smile again.

At the ends of both sides of this Black Dragon Pond, you can't even see it, let alone walk there.

"What do you mean?" asked the girl weakly.

"Here, there is no end. Li Xuan stretched out his hand and pointed to the Black Dragon Pond under his feet and said indifferently.

"There is no end, how can there be no end?" the girl looked incredulous.

Li Xuan looked at her and asked with an evil smile: "Why can't there be no end, let me ask you, is there an end to our world?"

The girl was stunned for a moment before asking, "You don't mean that this place is the same as the earth, it is round, right?"

"You're not too stupid. Li Xuan said with a wicked smile.

The girl suddenly looked up and looked at the sky.

"Then you have to leave here?" the girl asked, pointing to the sky above her head with an innocent expression.

"If you can fly, you can try. Li Xuan grinned.

"Uh-" The girl was dumbfounded, if she could fly, would she still get lost?

"As a grandmaster-level powerhouse, can't you fly?" the girl muttered.

Li Xuan didn't know if he heard her whispering, he suddenly squatted down and picked up a stone from the ground.

With a whoosh, the stone shot straight into the air.

Boom –

I don't know how long it has been, and there was a muffled sound in the ears of Li Xuan and the girl.

Above the sky, where Li Xuan was hit with a stone, the appearance of black scales faintly appeared.

"This is?" While the girl was surprised that Li Xuan could throw the stone so high, she couldn't help but wonder.

Li Xuan took a deep breath and slowly spit out two words from his mouth: "Immortal Prison!"

No wonder Li Xuan felt a little familiar when he came to the Black Dragon Pool, it turned out that this Black Dragon Pool was actually an immortal prison!

Immortals can live forever, and hell will not be collected, so the immortal prison was born!

There is no way to immortal prison, and those who are heinous will break into it.

There is no door to the immortal prison, the dead do not enter, and the living do not come out.

When a person dies, it proves that it is impossible to be an immortal, and the immortal prison does not accept the dead.

But people are alive, but there is no way to prove that they are not immortals, so they don't come out of the living.

Li Xuan should have thought of it a long time ago, as early as when he heard Zhao Tianlong and others say that "the dead can't get in, and the living can't get out", he should have thought that this was an immortal prison.

It's strange, it's because he doesn't know much about the Immortal Prison.

In his previous life, Li Xuan had only felt the immortal prison once from a distance, and the dead silence with no vitality and no aura could simply make the immortals go crazy.

Li Xuan was a little puzzled, on this earth, I'm afraid there is not even an immortal who can live forever, right?

So why does there exist a fairy prison here?

Moreover, according to Li Xuan's perception, in this immortal prison, I am afraid that there is no immortal who is imprisoned.

If you really want to force it to say something, it will probably be only Li Xuan who just broke in......

"This is troublesome, since ancient times, anyone who has entered the immortal prison has never heard of anyone who got out alive. Li Xuan's expression became more and more solemn.

"Immortal Prison, what Immortal Prison?" the girl behind him was still puzzled.

"It is a cage, the sky is the cage, the earth is the prison, and the person who collects the corpse is the jailer, and only the dead are let out. Li Xuan couldn't laugh anymore, he frowned slightly, and explained to the girl.

"The legendary painting is a prison?" asked the girl in surprise.

"You can understand it that way. Li Xuan glanced at the other party deeply and said lightly.

"Then we-" The girl didn't know what came to mind, maybe it was a certain song by some drug-addicted singer, she asked with a slightly red face.

"Let's find someone first, and then find the person I'm looking for. Li Xuan sighed helplessly.

"Looking for someone, you came to such a ghost place just to find someone?" The girl looked at Li Xuan in disbelief, she didn't expect that this Li Xuan risked not being able to get out, and plunged into the Black Dragon Pool, just to find someone.

"What a lot of hatred and resentment it takes for you to find here. The girl muttered again.

Li Xuan glanced at her and said, "He's my brother!"

"Brother, even if my own mother falls here, I will never follow up!" the girl said resolutely.

"The blood of the killer is cold. Li Xuan glanced at the other party and walked straight forward.

"Hmph, your blood is cold, you know it's this kind of place, but you still want to bring people in. The girl snorted and followed closely behind Li Xuan.

With a bang, she bumped into Li Xuan's back.

"I warned you, you had to follow up. Li Xuan stopped, and said without the slightest joy or anger in his voice.

Li Xuan, who restrained the evil smile on his face, made the girl feel even more frightened.

"Okay, okay, I insisted on following up on it. The girl stretched out her hand and rubbed her painful head, snorted, and complained to herself: "What brother, it's hard to protect yourself, what brother do you want to find......"
