Chapter 2687 Prehistoric Heart!

Those towering ancient trees glowed all over, like transparent crystals, and their tentacles kept swinging, forming an extremely mysterious natural illusion formation with each other.

Ling Xiao can feel the extremely powerful spiritual energy in it, which is as vast as the sea, and the spiritual energy of every towering ancient tree is far superior to the powerful Tianzun.

Those tentacles and strange fragrance formed a powerful natural illusion, which made the strong ones sink continuously.

If Ling Xiao hadn't smashed a towering ancient tree with his powerful body, it would have been extremely difficult for him to leave the range covered by the great array of natural illusions.

However, what Ling Xiao didn't expect was that hundreds of holy kings had fallen here.

Those corpses exude immortal waves. The strong body of the holy king can be immortal for hundreds of millions of years. It contains the power of the law of the great way. It can be called the body of law. So many corpses of the holy king gather together, the scene is incomparable shocked.

"These holy kings are probably the ones who broke into the Great Desolate Secret Realm for hundreds of millions of years. It's just that they couldn't leave the natural illusion, and their souls collapsed, leaving only a body in the end! In this way, I'm afraid this place has already been destroyed. It's not Eternal Asgard!"

Ling Xiao thought to himself, a sharp look appeared in his eyes.

The space where Ling Xiao lives is like an extremely huge underground cave, surrounded by gray, only a faint light flickers, the surrounding air is extremely hot, and towering ancient trees with glowing lights rise from the ground. It looks very weird.

When facing the endless chaotic flames and magma in the first level, Ling Xiao was a little skeptical, because such a vast source of flames is difficult for even a strong emperor to arrange.

And the towering ancient trees in front of him, although Ling Xiao didn't know what kind of creatures they were, they had grown for hundreds of millions of years, contained a majestic breath of life, and their spiritual energy was extremely powerful.

The environment here looks extremely real, and Ling Xiao suspects that this place is no longer the Eternal Heavenly Palace.

"It looks like it's deep underground. Could it be that this is the underground of the Primordial Secret Realm?"

Ling Xiao thought secretly in his heart.

But soon, Ling Xiao was attracted by the scene in front of him.

He walked out of the range covered by the large array of natural illusions, and suddenly noticed a faint light flickering in front of him, which looked extremely pure and contained powerful fluctuations of power.

Ling Xiao stepped forward,

There is gray mist all around, but the light ahead is getting brighter and brighter, and finally it looks like a bright sun bursting out, emitting billions of brilliant rays of light.

It was only at this time that Ling Xiao realized that the light source of this space was right in front of his eyes. After he passed through the gray and chaotic mist, there was no longer any obstacle, and the scene in front of him was presented in his eyes very clearly. before.

In the void in front of Ling Xiao, there is a strange spar floating, which looks as tall as a person, vaguely showing a human shape, with nine orifices, gushing out nine-colored glow, auspicious energy transpiring, and fairy light permeating, like It's a heart, beating slightly.

It was that spar that radiated infinite light and became the only light source in this mysterious space.

However, there is an incomparably huge transparent barrier around the spar. It doesn't look that big, only a hundred feet in size, but it looks like a mysterious halo, sealing the spar inside.

"What is this? Could it be that this spar is the third test that His Highness the Immortal Clan said?"

There was a trace of doubt in Ling Xiao's eyes.

That brilliant spar is like a hot sun, but also like a beating heart. Every beat exudes a strange rhythm and rhythm, making Ling Xiao's heart seem to be beating along with it.

Ling Xiao instinctively felt that this spar was not simple.

hold head high! Roar!

As if sensing Ling Xiao's arrival, four ancient and mysterious voices suddenly came from the transparent barrier.

The roar of a tiger shakes the void, the cry of a phoenix pierces through gold and cracks rocks, the roar of Xuanwu roars at the sea, and the roar of a unicorn shakes the earth...

On that transparent enchantment, four figures with terrifying auras suddenly appeared, a giant white tiger, a phoenix shrouded in endless flames, a ferocious basalt that overwhelmed the river, and a figure that radiated five colors of light, full of aura. The steaming unicorn.

White Tiger, Phoenix, Xuanwu, Qilin!

The images of the four holy beasts appeared on the barrier, causing the barrier to tremble slightly.

For some reason, Ling Xiao felt that the four holy beasts in front of him were not complete, and there seemed to be something vaguely missing to be able to completely open the seal of this transparent enchantment.

"Could it be...is there still a lack of the ancient ancestor dragon?"

Ling Xiao couldn't help but feel his heart skip a beat.

He had a hunch that when he saw the bright spar in front of him, his blood seemed to be boiling, and he wanted to rush out of the body, bursting out with a vast sound of dragon chant, and the four holy beasts echo each other.

It seems that as long as the blood of the ancestor dragon in Ling Xiao's body flies out, the ancient ancestor dragon can be transformed into the image of the five holy beasts, and the sealing barrier in front of him can be opened.

"His Highness of the Immortal Clan's real purpose is this spar!"

Ling Xiao's heart moved, and in a blink of an eye, he seemed to perceive the truth hidden behind the thick fog.

Everything is explained.

His Royal Highness of the Immortal Clan held members of the Four Great Saint Clans, but instead of killing Ling Xiao, he asked Ling Xiao to accept the so-called three-pass test.

This so-called three-pass test was not left by His Royal Highness of the Immortal Clan at all. It is probably a crisis that existed in the creation of heaven and earth.

Whether it is the chaotic flames, the natural illusion formation, or even the transparent barrier in front of him, they are probably all to protect this strange spar.

If the real purpose of His Royal Highness of the Immortal Clan is this spar, then all Ling Xiao's doubts can be explained clearly.

It is precisely because Ling Xiao has the blood of the ancestral dragon and is so powerful that he can pass the test of the previous two tests. As long as Ling Xiao opens the sealing barrier in front of him, I am afraid that His Royal Highness from the Immortal Clan will appear immediately to snatch the strange crystal stone.

This sounds like a conspiracy, but it is also a conspiracy.

The members of the Four Great Saint Clans are in the hands of His Royal Highness the Immortal Clan. If Ling Xiao wants to save them, he can only follow His Highness the Immortal Clan's request.

As for why the blood essence of the ancestors of the five saint races is needed to open this seal, it is easier to understand. After all, this prehistoric secret realm was originally left by the ancestors of the five saint races. This spar may be the ancient ancestor dragon Wait for the treasure left by the five holy beasts.

It's a pity that even Ling Xiao doesn't know what this spar is.

"Huh? It turned out to be the heart of the wild?"

At this moment, an old and surprised voice sounded in Ling Xiao's sea of ​​consciousness.
