The Immortal Secret Realm has been sealed for 10,000 years, just like an unexplored and unexplored world, full of all kinds of heavenly and earthly treasures.

But the demon beasts in it are also very powerful, and many people fall into the belly of the demon when they are looking for treasure.

Ling Xiao walked through this barren mountain, and saw the powerful Medicine King a few times in the middle, swallowing the essence of the sun and the moon on the top of the mountain, exuding an incomparably powerful aura.

However, Ling Xiao is not an opponent for the time being, so after seeing it from a distance, he automatically bypassed.

"The outer area of the Immortal Secret Realm has no effect on me, my current physical strength has not yet reached the limit, if I want to refine my physical body to perfection and reach the critical point of breaking through to the body of the flying dragon, it seems that I can only go to a few secret realms in the middle area!"

A trace of essence flashed in Ling Xiao's eyes, and he thought secretly.

The Immortal Secret Realm is incomparably vast, and the area from the entrance to 50,000 li is a peripheral area, and most of them are demon beasts below the fifth order, although there are also some sixth-order demon beasts and even demon kings, but that kind of existence is too rare.

And the land of 50,000 to 80,000 li is the middle area, and there are many sixth-order demon beasts here, and there are some cultivation secret realms left by the Immortal Sect back then, which are very precious.

The land of 80,000 to 100,000 li is the core area, where there are countless precious treasures of the Immortal Gate, and of course, there are many demon king-level powerhouses.

As for 100,000 miles away, it is a void crack and a dangerous forbidden area, which is not a place that ordinary people can set foot in at all.

There is a mysterious place in the middle area, which is of great benefit to Ling Xiao for refining the power of the physical body.

Just as Ling Xiao was heading towards the middle area, outside the Immortal Secret Realm.

A sloppy old man wearing a shabby Taoist robe with a big gray head flew across the air on top of a big gourd, and the target was the stone gate of the Immortal Secret Realm.

"The secret realm of immortality has finally opened......! My mission is coming to an end!"

The old man poured a sip of wine, and there was a trace of vicissitudes and sharpness in his old and cloudy eyes.

He stared at the stone gate, his face was full of emotion, holding the big gourd, and flew into the stone gate crookedly.

There was a layer of white light on his body, endless, vast and pure, if Ling Xiao could see it, he would definitely exclaim, because this old man had also cultivated the Immortal Qi Refining Technique!

Ling Xiao traveled all the way to the depths of the Immortal Secret Realm, crossing many mountain ranges, collecting elixirs and hunting powerful demon beasts along the way.

However, during this time, Ling Xiao encountered some trouble.

As long as it was a precious elixir that Ling Xiao had taken a look at, after he killed the demon beast that guarded the elixir, he found that the elixir was gone.

"Am I being targeted by some strange being?"

Ling Xiao's eyes flashed coldly, and he felt a chill in his back.

Even if he locked it with the power of the primordial god, those precious elixirs disappeared silently.

And later, not only the elixir, but even those powerful demon beasts, after being killed by Ling Xiao, quickly seemed to have been drained of their essence and turned into a dry bone.

"This is the power of devouring?"

After carefully investigating a few times, Ling Xiao finally relied on some subtle traces to see that those elixirs and demon beast corpses were devoured by a powerful devouring force that had devoured vitality and essence, which is why such a scene appeared.

"Could it be...... Is it it?"

Ling Xiao felt the strange and familiar devouring power, as if he had thought of something, and there was a hint of excitement in his eyes.

"Ten thousand years have passed, it can't be alive! If it's still alive, it should have become a god at this moment and left this world! But ...... How can there be a smell of it here?"

Ling Xiao's eyes flickered, and he was a little confused.

"But if you want to be sure, give it a try, and the old boy should appear!" Ling Xiao's mouth showed a curvature.

He still continued to move forward, continued to kill the demon beasts, and watched as those demon beasts and elixirs were devoured in energy and turned into nothingness.

And Ling Xiao himself used the elixir he already had to practice into a transparent spiritual liquid, like an elixir, exuding a rich fragrance, which made people feel refreshed when they heard it.

Airplanes!

Ling Xiao poured a cup of spiritual liquid from the glass cup, slowly placed it on the ground, and the runes in his hand were permeated, sealing the void around the glass cup, only the fragrance of the spiritual liquid could still be emitted, spreading towards the surroundings.

Ling Xiao himself, his figure flashed, and his aura was constricted to the extreme, hiding on a towering ancient tree.

Buzz!

Ling Xiao saw that around the glass cup, an invisible ripple rippled in the void, as if there was a trace of mysterious power coming towards the glass cup.

It's just that the area around the glass cup was blocked by Ling Xiao with runes, so that mysterious power couldn't penetrate the power of the runes no matter what, let alone touch the liquid inside the glass cup.

"It's coming!"

Ling Xiao's eyes flashed, and he immediately saw a big bluestone in the distance, probing his brain, and a black goat came out.

The goat looked quite extraordinary, with a faint aura, black hair as shiny as satin, two golden horns, and fangs in its mouth, which looked sharp.

A pair of eyes are very spiritual, with a humanized excitement, carefully moving towards the glass cup.

The liquid in the glass cup seemed to have a fatal attraction to the goat, making its eyes glow.

However, the goat did not act rashly, and after carefully inspecting the surroundings to make sure that there was no danger, he shook his head and walked over.

"Is it really?"

Ling Xiao was shocked, and a look of surprise and inexplicability appeared in his eyes, and he was extremely excited.

In his previous life, everyone knew that Ling Xiao was named the Heaven Swallowing Supreme, the head of the top ten titled supremes, and he was powerful and suppressed the enemies of the world, relying on the Heaven Swallowing Secret Technique.

But others didn't know that Ling Xiao was able to get the Heaven Devouring Secret Technique because of a great opportunity.

10,000 years ago, when Ling Xiao was a teenager, he once strayed into an ancient ruin, in which he encountered a mysterious bone, and the runes on the bone were filled with records, recording the secret art of swallowing the sky.

And Ling Xiao was in that ancient ruins, and at the same time he encountered a black goat, which was already a cultivator of the Demon King at that time, and also practiced the secret art of swallowing the sky, and even left the ancient ruins with Ling Xiao later and came to the God of War Continent.

When Ling Xiao went to the tomb of the Red Dragon God of War with the True Dragon Supreme in his previous life, the goat had also broken through to the realm of the Demon Venerable, and in the wild demon domain, he commanded hundreds of millions of demon beasts, so it was not majestic.
