Sure enough, under the golden light of Li Xuan's eyes, there was a formation that showed its true form, it was a concealment formation, and it was also a bloodline suppression formation, which could maintain the true dragon aura here for ten thousand years.

This is only the outermost formation, it doesn't have much lethality, and it can't trap the enemy.

He had the golden light to perceive the nodes of the formation, passed through the formation, and walked into the interior of the underground palace.

The real dragon's nest is made of coiled dragon wood, similar to the bird's nest on the tree, but it is the difference between heaven and earth.

As soon as the formation passed, the rich Yimu immortal qi diffused, and the vitality here was vibrant, and all kinds of elixirs grew, among them, the thousand-year-old elixir can be seen everywhere, which is the elixir of 10,000 years, and there are also one or two plants.

The elixir of ten thousand years, although it is not an immortal medicine, but in terms of medicinal efficacy, it is not a weak elixir.

After all, the spiritual power accumulated by an elixir for 10,000 years is extremely huge and terrifying.

However, Li Xuan's gaze was locked on a small grass that was only a foot long.

Just that little grass is better than the thousands of elixirs here!

With a hint of excitement in Li Xuan's eyes, he carefully walked to the side of the little grass, his eyes staring, and joy surged.

This little grass can't live and die, the flesh and bones, even the medicinal power, are not as strong as those 10,000-year-old elixirs, but this little grass has three leaves, and above the leaves, the fine dragon scales are dense, this is not a mortal spirit, but an immortal saint!

"Ambergris!"

True dragons are born with tens of thousands of years of lifespan, and for creatures like true dragons, cultivation is sleeping. Because the true dragon has one of the highest bloodlines in this universe, it is sleeping every day, and its cultivation can continue to grow, and it is even no worse than the geniuses of other races!

Therefore, the true dragon will often forge a nest and then stay in the nest to sleep, so as to cultivate. When the true dragon sleeps, it coils around its true body, and ambergris drips from its mouth, and it falls on a small grass that grows with the breath of the true dragon, and ambergris grass will be born.

Ambergris grass, no flowers and no fruits, the leaves are dense and scaly, and it has the effect of avoiding death and prolonging life!

If the dying man takes it, he will be able to immobilize the wound and not die until there is a cure for the wound and save his life.

Li Xuan doesn't value this role of ambergris, he has many means, in this world, I'm afraid no one can force him to that role. However, ambergris is one of the main medicines of the elixir, and the elixir is somewhat important to Li Xuan.

He carefully dug out the ambergris grass and planted it in the second heaven, only there, Otogi immortal energy, could maintain the growth of this ambergris grass.

After digging the ambergris grass, the rest of the elixir naturally can't be let go, after all, so many 10,000-year-old elixirs, thousand-year-old elixirs, used for alchemy, are all precious high-grade elixirs.

After Li Xuan dug up the elixir, he stood in front of the real dragon's nest, which was not connected to the rest of the place, every Panlong wood of the real dragon's nest was refined by the real dragon with the secret method of the dragon clan, which seemed to be built at random, but in fact it was arranged into a mysterious formation, this formation, with the Panlong wood as the source, was endlessly drawn from the void to absorb the immortal qi of Yimu.

Therefore, the Yimu immortal qi here will be so strong, otherwise, even if there are thousands of Panlong wood, the Yimu immortal qi here will not be so strong. Moreover, these coiled dragon trees are not real immortal trees, but real coiled dragon wood seeds, which take root and sprout in this mortal world, and give birth to the best spirit wood.

Otherwise, how precious the immortal wood is, even if it is a real dragon, in this mortal world, I don't want to get so many immortal trees.

It's just that if you want to enter the real dragon's lair, it's not that simple.

Li Xuan was able to easily come here because he could see through the reality of the formation, otherwise, even if it was a sea clan in the realm of tribulation, he would be suppressed by the true dragon bloodline and would not dare to go deeper.

Even if there is really a sea clan, if they can break through the formation and enter this true dragon's nest, they will never want to enter this true dragon's nest.

Because, this true dragon's nest has a terrible prohibition, and those who are not of dragon bloodline are not allowed to enter.

In the body of the human race, there is a trace of true dragon blood, otherwise the emperor of the human race would not dare to claim to be the true dragon emperor.

It is all because the emperor of the human race is nourished by the dragon qi and the true dragon blood in his body is awakened, so he can suppress the capital of a country with his personal body, so that the demons and evil do not dare to enter, and the monks do not dare to come lightly.

As a human race, Li Xuan originally had a trace of dragon bloodline in his body, but since he was reborn and reborn, only the purest human bloodline was left in his body!

In this world, in terms of the purity of blood, no one can stand out from Li Xuanqi!

The purity of his bloodline is already comparable to those first human races in ancient times, and he has never been born with any race.

There are peerless geniuses among the human race, some of them have rich blood in their bodies, and they can practice the exercises and spells of the dragon clan, and even, cultivate their physique, refine the blood of the dragon clan, and when they cross the catastrophe, they can fade away from their human body, incarnate as a real dragon, and travel the sky!

There are even people who have phoenix bloodline in their bodies, and if they cultivate the bloodline to the depths of the essence, they can be reborn from the fire and turn into a true phoenix!

Those who have Xuanwu bloodline in their bodies have strong physique and amazing defenses, and can be turned into Xuanwu.

For most human races, the activation of the alien bloodlines in their bodies is an excellent thing, because these bloodlines will bring them the most top-level cultivation talents!

However, their eyes are all in the present, and they do not see the far future.

What is a true immortal?

Therefore, those who have alien bloodlines, once they cultivate their bloodlines and survive the Heavenly Tribulation, they will turn into true dragons, true phoenixes, and so on.

And any monk, after ascending, will reshape the immortal body in the ascension pool.

At that time, there will only be one bloodline in the body, or the blood of the human race, or some kind of foreign bloodline. Naturally, the direct descendants of the human race and the alien race are no longer listed.

And that's just one aspect. On the other hand, it's about the future.

In the fairy road, only truth and purity. Those who are on the path of immortals, the farther they go, the more pure the bloodline in their bodies becomes.

For example, the true dragon, once the true dragon is promoted to the Golden Immortal Realm, it will transform into a five-clawed golden dragon, known as the dragon king. And when the true dragon steps into the realm of the Great Luo Golden Immortal, it will be like the ancestral dragon.

True Phoenix, Xuanwu, White Tiger, Dapeng, Peacock, etc., these demon clans are all like this.

And so it is with people!

Those who have achieved immortal saints with human bodies, such as the Eight Immortals, have you ever heard of what demon bloodline they have in their bodies?

That Erlang Xiansheng Zhenjun is a demigod born from the gods and mortals, and when he cultivates, his talent is amazing, but when he succeeds in cultivation, the blood of the human race in his body becomes more and more scarce, and he is getting closer and closer to the gods.

Erlang God Yang Jian is like this, and so is his nephew, Liu Shenxiang.

Any race, bloodline, physique, cultivation to the end, only one pure word remains!

Especially for sanctification, it is a pure word!

Because, the higher the cultivation, the stronger the luck, if you have mixed blood and blood in your body, and wait for you to preach, are you a saint of the human race, or a saint of a different race?
