Deep in the stratum, there is a pool about ten feet long, and the liquid in it is crystal clear in color, showing a rich blue color.

Ye Nan noticed that in this terrain, all the "dragon teeth" extended to the surroundings of this pool, like an underground stone forest, dense and intertwined.

There, there are naturally formed leylines, like blood vessels, that extend all the way to the inside of the "dragon's teeth", in which the blue liquid flows endlessly, achieving a perpetual cycle.

This discovery made Ye Nan think, and she ran the Origin Heaven Emperor Technique, and went all the way down one of the widest earth veins, and came to the front of this pool.

It is deep underground, but the area around the pool is not crowded, on the contrary, it is an underground cave that is large enough to accommodate dozens of people at the same time, but there is no exit and entrance, and only people like Ye Nan who have mastered the source art can enter.

"Boom"

As soon as he stepped out of the leyline, Ye Nan felt the blood in his body rumbling and galloping.

This couldn't help but make her look awkward, and she looked more seriously at the pool full of blue liquid in front of her.

As seen on the ground, the pool was about ten feet long, made of dark brown rock, with no signs of man-made excavation, and was entirely natural.

Ye Nan noticed that the surface of these rocks cast into pools shone with a bone-like color, like some kind of weathered fossil.

She stepped forward and came to the edge of the pool, and her immaculate countenance was suddenly illuminated by a dreamy blue sheen.

"Ang"

A pitch-black dragon, almost completely evolved into a dragon form, churning and undulating in this pool, setting off layers of waves.

Its black scales are like iron, and each piece of scale armor flashes with a metallic color, hovering in the air, covering the entire sky, and it can be seen that it is full of its huge body, shuttling and intertwining, densely packed.

Although this pool is only ten feet square, in Ye Nan's view, it seems to have become an endless blue sea, in which a divine dragon shuttles and swims, the dragon's eyes are majestic, and the dragon swings its tail, attracting thousands of blue waves and sweeping the sky.

At this moment, she once again saw clearly, where is the ocean, it is clearly a bright sea of stars, this unimaginably powerful god Jiao swims in it, the sun, moon and stars hang on its side, it is difficult to hide its world-shattering might!

In the next moment, Ye Nan was shocked, came back from his trance, and found that he was in a cold sweat.

In front of her, there was no dragon, and there was no blue sea, only a pool of azure crystal water, flowing quietly in it.

Ye Nan silently recalled the picture that had just come to mind, the figure of the black dragon that released endless divine power gradually coincided with the body of the mysterious boy, the slightly immature black dragon.

There was no doubt that the two were of the same race, and the young man's blood was as blue as it was, but it didn't have the depth of the pool.

At this moment, Ye Nan's gaze when he looked at the liquid in the pool again was already a little surprised.

According to the young man's words, there is a record in the Ziwei Star Domain that after the disappearance of the Taiyin Human Emperor, in the blank years before the Sun Saint Emperor's enlightenment, there was a true dragon that fell from outside the domain, it was covered in scaly wounds, and it was suspected that it had suffered heavy damage, and the leaked immortal light illuminated half of the sky.

For this reason, when he was in Hanhai City, Ye Nan deliberately found the relevant ancient books, and indeed found a record of this, but it was classified as a column of "Zhi Monsters", obviously the narrator did not think that this was a real thing.

In that record, it was mentioned that the blood that flowed from this true dragon was not crimson, but as blue as the blue sea!

At the beginning, Ye Nan, like most people, was skeptical of this account, even if it was said through the mouth of a young man who was the descendant of the "Ze" god, she still only regarded it as an ordinary historical rumor and didn't care too much.

But at this moment, after going deep into the underground of the "True Dragon's Severed Head" and witnessing such a pool of azure water, Ye Nan knew that this was definitely not an ordinary Zhiwei story, but a real thing!

This azure pool of water is actually a pool of blood, and the source of the blood is the first fierce general of the Taiyin Ancient Dynasty who fought with the emperor in the world eons ago-Ze!

What happened to the Emperor after he left? Since then, he has completely disappeared into the long river of history, and even the quasi-emperor Jiaolong, who has accompanied him to fight for half his life, has suffered unimaginable heavy losses!

Ye Nan can imagine that the dragon that has obtained the quasi-emperor realm, after encountering an accident, crossed the endless galaxy, just to return to his homeland again and bury himself.

It's just that she has doubts in her heart, if this is really the blood of the quasi-emperor, the qi contained in it is afraid that she will tear herself apart as soon as she steps out of the leyline, let alone be able to bring herself closer safely.

Thinking of this, Ye Nan ran the source of the Heavenly Divine Sense, swept the surrounding landforms one by one, and the doubts in his heart were gradually answered.

The reason for all this is precisely the rare terrain she is in at the moment - the decapitation of the real dragon.

The pool of quasi-emperor blood flowed through the huge rocks along the underground leylines, and the quasi-emperor law acted on the rocks, changing its original structure, making it take on a bone-like texture.

This process is extremely long, spanning almost the entire primeval era, and these huge rocks have gradually become "dragon teeth", intertwined in this vast land.

In this process, the quasi-emperor qi and quasi-emperor killing intent in it were all integrated into this terrain, accelerating the formation of this terrain, so that this pool of blood and water had absorbed the terrifying quasi-emperor killing intent, and no longer made people unapproachable.

At this moment, through his own understanding, Ye Nan really knew the complete formation process of the terrain of the "True Dragon Severed Head".

It actually takes a quasi-emperor or quasi-emperor realm above the Jiaolong to fall, and its essence and blood interact with the surrounding terrain to create such a rare landform through the ages.

The harshness of its conditions made Ye Nan speechless.

After all, looking at the entire ancient history, not to mention the imperial realm, how many dragons can really reach the quasi-imperial realm?

However, as long as the existence reaches this realm, it is almost a god, and there is no rival in the starry sky, and it is an extremely difficult thing to want them to fall.

The real dragon has a severed head, and it lives up to its name!

At this moment, Ye Nan once again thought of the next evolution of the terrain of the "True Dragon Severed Head", which was called "Dragon Blood".

In her eyes, the passage of time seemed to speed up a thousand, ten thousand times, the stars shifted, the vicissitudes of life, the pool of blood slowly rose, and all the dragon teeth were also accelerating their transformation.

When the blood pool floated to the surface, all the dragon teeth were connected together, forming a brilliant peerless dragon vein.

And all the essence in the blood pool was also condensed in one place, turned into a piece of blood god source, and was buried in this peerless dragon vein.

The world's rare deadly murderous place, "Dragon Blood", was deduced in Ye Nan's sea of knowledge.

After obtaining the Yuantian Book and the Yuantian Emperor, Ye Nan directly entered the starry sky, and there was no chance to practice this immortal method at all.

Right now, the rare terrain "True Dragon Severed Head" is taking shape in front of her eyes, and the back of this terrain is still a "dragon blood" that makes people talk about it, Ye Nan will not let go of this rare opportunity if she says anything.

After the deduction was completed, Ye Nan nodded, his eyes were smart and detached, and he glanced in all directions.

Millions of years have passed, and if there is no interference, this place will definitely evolve into "dragon blood" through the "true dragon's severed head", thus harvesting the lives of countless monks.

Thinking of this, she looked back and stared at the key to all this-the quasi-emperor blood pool.

But after a while, Ye Nan still stuck out her tongue, as if she was a little embarrassed, playful and smart.

Because, even if there is no such reason, she will not let go of this pool of blood containing the essence blood of the quasi-emperor, and the creation in it is unimaginable.

Ye Nan first gently touched the surface of the pool with her hand, and there was no stickiness and slippery blood, but a cool touch, like spring water, cold and refreshing.

"Wow"

She scooped up a puff of blue liquid, and a faint fragrance came to her face, which couldn't help but move Ye Nan's heart.

After millions of years, this cave buried deep in the ground is more like a fermentation pool, under the action of the "True Dragon Severed Head" terrain, the blood in it has undergone extremely mysterious changes, and has become another level of liquid, like elixir, no longer belongs to the category of blood.

"The next time I see that young man, if he still does something to me, I will strike lightly."

Ye Nan muttered to the pool, and then slowly stepped into it, letting her clothes get wet, and sat down on the spot.

Suddenly, an indescribable refreshment and coolness enveloped her, and the thin Jiao Blood Essence and the Quasi-Emperor Road continued to wash away Ye Nan's body.

This is a precious transformation, and it is also an opportunity that can be called against the sky, Ye Nan subconsciously operated the Heaven Devouring Demon Skill.

"Buzz!"

In an instant, the smoke boiled, and one after another brilliant fairy light spread out from the pool, some of Ye Nan's own, and some of the original contained in the pool water.

Ye Nan's bones clanged, and his flesh trembled slightly, as if he was being reborn.

During the previous tribulation, her body had suffered unimaginable damage, and although her physique had been greatly strengthened in the process, she was still left with some dark wounds that would be difficult to heal in the short term.

However, through such a pool of treasure liquid, the physique tempered by Ye Nan during the tribulation was completely completed, and his divine consciousness was also refined, becoming clearer and clearer, and gaining insight into the true nature of the world.

"Hmm"

The transformation of the body and the primordial spirit made Ye Nan groan in a low voice, which made people think about it and their blood gushing.

She felt that every bone and drop of blood in her body had been combed, and the flow of Dao power around her body was an unprecedented smoothness.

This process lasted for dozens of days, Ye Nan was like a bathing elf, the whole body was crystal clear, not stained with dust, the lines were exquisitely undulating, beautiful as a dream, ethereal and beautiful.

At this moment, her eyes were shining brightly, and she had already come to the Great Perfection of the Second Heaven of the Four Extremes.
