Upper Pole Aquila.

This kind of primeval desolate beast, in fact, Fang Yuan has long heard of the great name, but he doesn't know what the specific appearance of the eagle's bird egg is.

The Upper Pole Aquila is a Usoteric Ancient Desolate Beast, and an adult Upper Pole Aquila can freely travel between the Nine Ancient Heavens or the Cave Heavens.

It's an instinct that's extremely powerful.

Outside the primeval nine heavens, there are extremely thick Tiangang qi walls blocking each other. The cave is placed in the sky, and if you don't take the initiative to appear, it is extremely difficult to detect from the outside world.

But as long as the Upper Pole Aquila has been somewhere, it can follow its instincts, penetrate the void, and go back and forth.

It itself is an ancient desolate beast, with eight turns of combat power, and its flight speed is extremely fast, Hei Fan can search for such an egg of the Upper Pole Eagle, if there is no adventure, it must have cost a huge price.

The only flaw of the Shangji Tianyan is probably Shouyuan.

Its lifespan is only eighty years.

The lifespan of a normal mortal is a hundred years.

The dignified primeval beast, the lifespan of the Extreme Sky Eagle is actually not as good as that of mortals, and it is really a bit cheap. Other primeval desolate beasts, hundreds of thousands of years, hundreds of thousands of years of life, the Upper Pole Sky Eagle can't be compared at all.

However, it also has the means to prolong its life.

When it dies of natural old age, it lays an egg.

In this bird's egg, it contains all the memories of its past, even the accumulated traces of the Universe Dao.

When the young bird breaks out of its shell, the Upper Pole Eagle returns to its first life and grows up again, but it has memories of past lives and the accumulation of Dao marks. If nothing else, the Upper Pole Aquila will only get stronger and stronger.

Of course, the period of eggs and young birds is undoubtedly the most vulnerable time for the Upper Pole Aquila.

After understanding this, Fang Yuan boldly guessed: "This bird egg of the Upper Extreme Heavenly Eagle must have been deliberately left by Hei Fan!"

Why leave this egg?

Obviously, the Upper Pole Heavenly Eagle may have been to the Black Fan Cave Heaven. It is the bridge to the Black Mortal Cave Heaven.

The cave left behind by Hei Fan after his death. The Black Family Gu Immortals have been investigating. As far as Heicheng can remember, this exploration has been fruitless.

"Hei Fan's true biography is probably left in his own cave. This was not surprising, because he didn't have any esophageal means, so he left the Immortal Gu in the Immortal Aperture and fed it by himself. The most secure. ”

"And the problem of the catastrophe of the Black Fan Cave Heaven does not exist. According to Hei Cheng's memories, Hei Fan had obtained a fragment of the Nine Heavens of the Primeval Universe during his lifetime. If I'm right, Hei Fan must have integrated this fragment of the Nine Ancient Heavens into his own immortal aperture before he died. ”

"It's a pity that although he has no disasters so far, he has no longevity Gu, and the method of prolonging life he uses has also reached its limit. So it can only fall. ”

"But why are the eggs of the eagles in the eagle's nest dead?"

Fang Yuan faced another problem.

There may be two answers.

The first is naturally this Aquila egg. Already died of natural causes. Hei Fan left the eggs, and in order to prevent the eggs from hatching on their own, he used this Celestial Crystal Eagle's Nest to make a certain arrangement. But after a long time, no one came to inherit and open the Sky Crystal Eagle Nest. In this way, over time, the eggs are really completely dead.

The second possibility. The reason why the eggs of this Extreme Aquila are completely lifeless. It was completely done by Hei Fan himself. This egg is not really dead, and requires a specific technique to unseal it.

If it was the first possibility, then Fang Yuan would naturally not be able to reap more benefits, and could only harvest a Celestial Crystal Eagle's Nest and a dead egg of an Ancient Desolate Bird. However, the value of both is also very high.

From Fang Yuan's point of view. He certainly hoped that the second possibility.

But if it is the second possibility, then where is the specific method that can unseal the bird's egg?

"Assuming that's the second case, then how can I unseal this dead egg, let it regain its vitality, and even hatch it?" Fang Yuan fell into deep thought.

He thought about it for a long time. Clueless.

And no wonder.

Simply put, the egg is indeed completely dead. If it weren't for that, Fang Yuan wouldn't have been able to confirm this fact from the beginning.

"If I were Hei Fan, if I wanted to leave a dead egg and let future generations inherit my inheritance, I would definitely leave a solution to this matter. Fang Yuan suddenly had a flash of inspiration.

He found himself, subconsciously ignoring a method.

That was the refining techniques that Hei Fan had improved and deliberately handed down.

"It was these methods that I used to open the Celestial Crystal Eagle Nest. What if I use these methods to do something to this Heavenly Eagle Dead Egg?" Fang Yuan had a bold idea in his heart.

But he didn't take immediate action.

Because this is just a very pure speculation and idea, and there is no basis for facts.

Fang Yuan was very cautious, he began to use the wisdom Dao method, deeply analyze these Dao refining techniques, and focus on calculating.

He soon noticed something strange.

What's so weird?

There are some Dao refining killing moves, and Hei Fan has improved them inexplicably. The original Dao refining killing move is even better and better than his improved.

Hei Fan is so improved, it is simply deliberately unflattering.

What exactly does he want to do?

Fang Yuan suddenly thought of a passage in Hei Cheng's memory, a record of Hei Fan's life.

As an eight-turn Gu Immortal, Hei Fan likes to bring up his juniors in the late stage of his life, and he often teaches them: when studying, you should bring your own thinking, don't blindly worship, and don't copy all the experiences and achievements of your predecessors. Only by thinking about it and applying what you have learned can you go further on your own path to becoming a Gu Immortal.

Thinking of this, Fang Yuan looked at these Dao refining killing moves again, and he had a new feeling.

He tried to extract the killer moves of Hei Fan's "improvement failure", and he made another astonishing discovery.

"It turns out that these Dao refining killing moves are not a failure to improve, but a combination of them in everything, it is a brand new killing move!"

"Hei Fan's deliberate additions to these Dao refining and killing moves, if you look at them individually, are all failures. But when combined in everything, these additions can be combined to form a unified whole!"

What made Fang Yuan feel even more surprised was that this brand-new killing move actually belonged to the Blood Dao, a Blood Dao method.

Hei Fan, who is a dignified eight-turn celestial Dao, actually studies the Blood Dao?

This is not surprising.

Since the birth of the Blood Sea Ancestor, the power of the Blood Dao. Known to the world. On the one hand, the major super forces vigorously prohibit the development of the blood path, and on the other hand, they are secretly researching behind their backs.

This phenomenon even exists in the top ten ancient sects in Zhongzhou, not to mention the Northern Plains Gu Immortals who advocate combat power in a place like Beiyuan, which is a place of four wars?

For the Blood Dao, Fang Yuan was much more confident than the Refining Dao.

He is the realm of the Blood Dao Grandmaster! The Blood Dao is his old profession.

After a little research, Fang Yuan found that this Hei Fan was deliberately hidden. said that the blood refining killing move left behind was indeed aimed at the dead egg of the Upper Pole Eagle!

But this blood refining killing move is not comprehensive.

According to Fang Yuan's insight and blood path attainments, he could see that this blood path killing move was still unfinished in many places, and it was only a fragment of the next part.

Seeing this, Fang Yuan was not disappointed, but his eyes were shining.

"Hei Fan should master the complete blood refining killing moves. He used the first half to dispose of the dead egg of the Upper Pole Eagle. Then leave the lower half and give it to future generations. ”

But he didn't directly leave it to future generations, but hid this blood-killing move in an ingenious way. ”

"The purpose of doing this, firstly, is to test the younger generations, hoping that there will be an excellent Gu Immortal who can think for himself to inherit his inheritance. The second is also because the blood path cannot see the light. The dignified Heifan left a true biography. It's actually a blood path method, and I'm afraid it will cause a lot of turmoil if I say it. This is what Hei Fan doesn't want to see. ”

Fang Yuan is scheming. pushed himself and others, and for a while, he figured out Hei Fan's thoughts back then.

After figuring out this, Fang Yuan was even more convinced that this Upper Extreme Heavenly Eagle's dead egg was not dead, but was first used by Hei Fan with a special technique. It was processed.

And then it's easy!

Fang Yuan was no longer an immortal body, and it was easy to use the blood on his body.

However, just when he was about to refine the blood. He stopped suddenly.

"It's so dangerous! I almost didn't expect Hei Fan to have this kind of intention......" Fang Yuan had a cold sweat on his forehead.

Why did Hei Fan use the blood method specifically and leave it to future generations?

Doesn't that seem a little strange?

As we all know, Hei Fan is a great power of the Dao of Heaven, and to his extent, he can touch the bypass. The Celestial Dao Technique can definitely leave a legacy.

But what is he doing when he takes the blood path alone and gives up the Zeu Dao that he is best at?

I am afraid that there is only one answer to this question, and that is the method of the blood path, which can provide things that the means of the Dao of Heaven cannot.

What else could there be?

As a Blood Dao Grandmaster, Fang Yuan's first thought was bloodline certification!

Hei Fan left a legacy, and the expected target is the descendants of the Hei family. The Gu Immortals in the super family left a legacy, basically all of them are fertile and water-free from outsiders' fields, and the first condition is the descendants of the family. There are very few family Gu Immortals who have a clear idea and can let others inherit them.

Attitude Gu and Dao refining techniques passed down from generation to generation are only one or two of the means of prevention.

The method of blood refining, carrying out bloodline human evidence, is the third means of prevention.

"If it weren't for the descendants of the Black Family, and the blood flowing on his body was not the blood of the Black Family, then if he dared to refine this bird's egg with blood, he might attract backlash. What's more, it hatched the Upper Polar Eagle, but it was regarded as a mortal enemy by this primeval beast!"

Fang Yuan thought of this, and the cold sweat on his forehead was a little more.

Especially in the latter case, if it really provokes the primeval desolate beast, a mortal enemy like the eight-turn combat power, it is not a joke!

The speed of the Upper Pole Sky Eagle was extremely fast, and Fang Yuan couldn't shake it off at all. He himself was so weakly protected that he was almost certain to die.

"It seems that only by starting with the bloodline can we refine the bird's eggs. Fang Yuan wisely stopped.

A few days later.

Somewhere in the Supreme Immortal Aperture.

Heicheng was disheveled and looked haggard.

Fang Yuan manipulated a powerful immortal stiffness and flew slowly.

Heicheng was like an electric shock, his whole body trembled violently, his face was full of horror, and he shouted: "You, what do you want to do to me again?!"

In the past, Fang Yuan searched for his soul, and that's it. But in recent days, Fang Yuan has used all kinds of means to "torture" him, making him miserable and miserable.

Heicheng was captured by Fang Yuan, and when he fell to this step of the field, he was already completely resigned to his fate. What Gu Immortal's temperament is gone.

But even if he bit his tongue and killed himself, he couldn't.

Fang Yuan felt that Heicheng still had value that could be used, even if the Hei family had collapsed, Hei Loulan was still there.

Therefore, the black city is now a survival can't die.

"Don't worry, this time is probably the last time, I'm confident. Fang Yuan's manipulative force was immortal, and he smiled slightly.

Heicheng almost burst into tears, and he struggled violently: "Every time you say that, you say it is the last time! )
