Although the Taixu Sword Technique is only at the level of Tribulation, no matter how it is said, it is also a technique that makes Heavenly Immortals such as the Star Moon Fairy snatch it, and it is at least a high-level Immortal Method.

Moreover, according to the Star Moon Fairy, as long as the immortal realm exercises are cultivated to a certain high level and have enough immortal yuan power to accumulate, even if there are no follow-up exercises, they can advance to the next realm. It's just that in this way, the time consumed is too long, and maybe before it can be advanced, it has already died before the longevity is exhausted.

If this is done, the monk's own strength will be much weaker than that of the monk of the same rank.

But this situation is also common in the fairy world. You must know that the immortal exercises are not as good as ordinary exercises, most of the advanced exercises are in the hands of those immortal palaces and immortal clans, and if the ordinary immortal natives or casual cultivators want to obtain the exercises, they have to enter the immortal palace or the immortal clan to serve, and the grades of the exercises obtained are not very good, basically low-level immortal methods.

Of course, these immortal methods are not too easy to obtain. Unless the monk has made some merit or has good qualifications, he will make an exception and be given a complete exercise, and the vast majority of them are also incomplete.

Also, those casual cultivators are not high in cultivation and have average qualifications, and secondly, they have no background or backing, and it is already rare and valuable to be able to obtain a Immortal Realm Exercise.

......

After having a plan in his heart, Yuan Fei immediately held his breath and concentrated, as if he had entered the immortal cultivation realm at the beginning of that year, and felt the immortal aura permeating the nearby space.

Although Yuan Fei's condition at this time was not much different from that of mortals, his cultivation experience over thousands of years was vastly different.

As for the Taixu Sword Technique, Yuan Fei had studied it for many years as early as when he was in the human world, and now it has been firmly imprinted in his heart.

After a while, Yuan Fei felt a trace of strange aura flow into his body. It's just that this breath is too thin, and it dissipates as soon as it enters its body.

Yuan Fei was not in a hurry, his eyes were closed, and he absorbed the immortal qi with full concentration.

The same scene lasted until two months later. Fortunately, Yuan Fei had already been cleansed by the Book of Changes and separated from the mortal body, otherwise he would have died long ago if he hadn't eaten or drunk for so long like a mortal.

Suddenly, Yuan Fei, who had been standing still, opened his eyes after his eyelids twitched slightly, and two white sword qi surged out of them, and disappeared in a flash.

And the green ptarmigan seemed to have discovered something, and stood up with a "squeak" sound, which seemed to have murderous intent towards Yuan Fei.

However, at this moment, the cyan young eggs that had been standing still in the spiritual spring trembled slightly, and the egg shell "clicked" and cracked a thin slit, as if something was about to break out of the shell.

Seeing this, the green thunderbird no longer cared about Yuan Fei, who had just looked different, and his eyes all fell on the young eggs.

Yuan Fei was startled just now, but after seeing the green thunderbird's diverted attention, he breathed a sigh of relief.

Then, after reciting a few words silently with a slight movement of his lips, a black shadow flew out of his body, and silently disappeared into the void.

And the green ptarmigan, which was originally staring at the young eggs, suddenly moved, seemed to sense something, and immediately raised its head to look around.

At the same time, the ripples in the void moved, and two long bone blades appeared out of thin air, and slashed down like lightning.

The green thunderbird looked startled, and a layer of cyan electric light immediately appeared on the surface of its body, making a "crackling" explosion.

Then there was a flash of lightning, and the bird mysteriously disappeared.

The bone blade naturally slashed into the air with a single blow, and then a huge monster appeared. Several feet tall, covered with razor-like black hair, eyes glowing green, and fan-like palms each holding a strange long bone blade, it is undoubtedly a ghost baby.

In fact, Yuan Fei originally wanted to summon all the ghost babies and wood spirit incarnations, but so far, it has only just entered the qi refining period, let alone summoning two incarnations at the same time, it is already barely enough to be able to release the ghost baby.

The next moment, a few feet away, there was a flash of lightning, and the green thunderbird resurfaced again.

As soon as this bird appeared, it immediately became ferocious, and with a shake of its wings, countless wind blades condensed out, enveloping the ghost baby in it.

However, the ghost baby was very disdainful of this, and let the wind blade roar all over the body, but it could not cause the slightest damage to it.

The green thunderbird seemed to be very angry, and after a scream, layers of cyan electric light suddenly flashed all over its body.

Then the bird opened its mouth and squirted, and a cyan thunderbolt the thickness of an arm shot out, and almost in the blink of an eye, it appeared in front of the ghost baby, and struck down with a fierce blow.

Seeing this, the ghost baby's hideous face couldn't help but become solemn. But that's all, this ghost baby didn't say a word, but with the same big mouth, he actually spit out a black thunderbolt, and the cyan thunder and lightning collided in one place.

With a loud bang, the blue and black electric lights were intertwined for a while, and it took a full time for a cup of tea to disappear at the same time after a muffled sound.

After the ghost baby let out a sneer, his arms shook suddenly, and the bone blade in his hand disappeared in a flash.

Seeing this, the green thunderbird couldn't help but be surprised, and quickly shook its wings, and layers of wind walls emerged, protecting it impenetrably.

Not only that, the bird shook its feathers, and a trace of cyan thunder light came out of its body, and the same inner and outer three layers condensed into a layer of thunder and lightning light shield, forming a huge ball of light.

At this moment, the ripples in the void moved, and two bone blades shot out from it, slashing fiercely on the thick ball of light.

The bursts of tearing sounds of "snort" sounded one after another, and the two bone blades were surprisingly sharp, and they actually tore apart the layers of protective light shields little by little, and finally with a loud "boom", the entire ball of light shattered.

It's just that it's empty, and there's no shadow of the green ptarmigan at all.

However, instead of having a trace of different colors, the ghost baby flicked the corners of his mouth, and two rays of light shot out from a pair of green and faint eyes, and directly submerged somewhere in the void.

Immediately afterwards, the thunder light in the void was released, and the green thunderbird appeared out of thin air, and it had been entangled in the body by the green light filament, allowing it to release the wind blade in the sky, or the arc of the blue light flickering, all of which did not have the slightest effect.

Seeing this, the ghost baby couldn't help but sneer, and then took a big mouthful, and the entire body of the green thunderbird suddenly shrank under the green light filament, and was directly swallowed by the ghost baby.

After doing this, the ghost baby's gaze fell on the three spirit eggs in the spiritual spring.

After licking his thick lips with fiery eyes, he was about to stride to grab the spirit egg.

Seeing this, Yuan Fei couldn't help frowning, and then recited an obscure spell in his mouth again.

The ghost baby immediately roared in pain, and then his body seemed to be spinning, and the black light on his body flashed, and he turned into a ghost baby body that was a foot long and covered with black hair, and then disappeared into Yuan Fei's body in a flash.

Fortunately, Yuan Fei still has a forbidden mantra for controlling the incarnation, otherwise, with his current cultivation, I am afraid that even if he can solve the current crisis, he is very likely to be the target of the ghost baby's hunting in the next moment.

It is no wonder that Yuan Fei's cultivation is only in the Qi refining period now, and the difference between him and the ghost baby is not just a big realm. However, its realm is still there, and coupled with the strangeness of the Splitting Element Splitting Divine Technique, it can also be controlled.

It's just that, with the current situation, he doesn't dare to summon the incarnation easily.

In addition, what puzzled Yuan Fei was that the strength of this green thunderbird seemed to be unworthy of the name. Originally, he was worried that the avatar would not be able to resist the bird, so he released the ghost baby that was much stronger.

Who knew that this bird was so easily killed by the ghost baby.

After pondering for a while, Yuan Fei came over a little suddenly.

If he is not mistaken, it is very likely that this green thunderbird has undergone some kind of mutation after the change of heaven and earth, and its supernatural powers are far inferior to before, but it has left a bloodline because of this, so that it can continue to this day.

And just as Yuan Fei's mind turned, the young egg in the spiritual spring, which was already a little cracked, actually shattered with a "click", and a young bird that was only a few feet in size and covered with wet pale cyan feathers appeared.

As soon as the bird hatched, it saw Yuan Fei not far away, with a mouth "chirping", and came to Yuan Fei with his feathers struggling, jumping up and down, as if Yuan Fei was recognized as his mother.

Seeing this, Yuan Fei couldn't help but feel a little guilty in his heart. If it weren't for this, the blue ptarmigan wouldn't have fallen. But in order to save his life, he had to do it as a last resort.

However, since this young bird of green thunder recognized itself as its biological mother, it was also saved from recovering it, and it was carrying the Reverse Spirit Transformation Pill, it might not be impossible for this bird to recover the ancestral bloodline.

Thinking of this, Yuan Fei shook his wrist and took out a few pills.

The young bird of Qinglei immediately smelled a certain aroma, and swallowed all the pills in a few clicks, and became intimate with Yuan Fei very obediently.

Seeing this, Yuan Fei had a rare smile on his face.

......

Time flies, and in the blink of an eye, Yuan Fei has appeared in this cave for three hundred years.

At the beginning, it took Yuan Fei almost a full ten years to restore the damaged meridians in his body, and his body was finally able to move freely, and his cultivation had successfully reached the Rongyuan period.

However, Yuan Fei did not leave the cave.

It's no wonder that he doesn't know the outside environment, and if he encounters any crisis, he is afraid that his life will be lost. Anyway, they need to re-practice the exercises, it's the same everywhere, so why bother to find another place. Moreover, this is the nest of the Green Thunderbird, even if there are monsters in the nearby area, they will not be bored under mutual jealousy, so this place has become safer.

And because of the crisis that may arise in the outside world, Yuan Fei has been practicing penance almost day and night over the years, and there has never been a day of interruption. Until now, his cultivation has not only returned to the level of the Tribulation, but also has made inch, and it is not far from the peak of the early stage of the Tribulation.

Of course, the fact that its cultivation was able to grow so rapidly was not unrelated to the fact that it had already thoroughly studied the Taixu Sword Technique, but also had something to do with the rich immortal qi here.

Thinking about it, no matter how you say it, the green thunderbird is also a tribulation cultivation, and the nest chosen will naturally not be too bad, not to mention that there is also a spiritual spring that breeds the qi of immortals here, which is even more icing on the cake.

It's just that Yuan Fei regrets that when he crossed the space passage back then, almost all the treasures in his body were destroyed, and even the Demon Slayer Nail Spirit Treasure was unfortunately lost in it, and now only the natal magic weapons 'Fire Devouring True Demon Sword' and 'Golden Yuan Lock', which had long been dissolved in his palm, were just left.
