The sword blank flew into the formation, and the girl immediately shot into the formation with a few spells, and she heard a buzzing sound piercing, and the formation instantly shone brightly!

Xia Yin, who was next to him, hurriedly threw the dozens of auxiliary materials that had been prepared into the formation with his hand.

The formation automatically absorbed dozens of auxiliary materials, and then derived a series of mysterious runes, wrapping the flying sword, and rotating rapidly in the formation, getting faster and faster, and finally unable to see it clearly with the naked eye......

After half an hour, the light of the formation gradually subsided.

And the rapidly spinning flying sword finally stopped, suspended in the middle of the formation.

At this time, the flying sword no longer has the slightest roughness of the sword blank, and it can't be seen that it has fused three main materials and dozens of auxiliary materials, and the whole has become crystal clear, as thin as a cicada's wings, three inches long, and an incomparable sharp aura, even through the formation, it still makes Xia Yin and Zhang Rouran feel the trembling of the blade!

The girl bent her fingers, and the flying sword that had been refined and formed suddenly shot towards the edge of the formation, and finally inserted into the scabbard, quietly suspended at the edge of the formation.

And at the edge of this formation, there were still one hundred and twenty-four scabbard-like phantoms suspended.

"Alright, let's continue to refine the next flying sword!"

At this time, the girl revealed shrewdness and ability in her voice!

When Xia Yin heard this, he bent his fingers, and a second sword blank flew out of the sword trough, suspended in the air, and was also wrapped by Yuehua Jinyan.

And Zhang Rouran pinched the mantra, shot out a few smelting runes, and flew into the sword blank......

The sword blank quickly turns red!

......

In the following time, with the continuous actions of Xia Yin and Zhang Rouran, there were constantly flying swords that had been fully refined and formed in the formation, which were inserted into the phantom of the scabbard.

Seventeen days later, all the sword blanks were sacrificed and refined into real flying swords.

A full one hundred and twenty-five flying swords were inserted into the phantom scabbards around the formation, forming a large circular circle!

At this time, Xia Yin and Zhang Rouran's faces became a little tired.

However, the two did not dare to pause.

"Alright, activate the Flying Sword Sacrifice Formation of the Mother and Son!"

As soon as Xia Yin's words fell, Zhang Rouran had already shot out more than a dozen magic decisions in a row, merging into another formation next to him.

Buzz.

This formation was in full swing in an instant!

This time, as the formation was activated, I saw countless runes flying up from the formation, and they automatically evolved into five flying sword phantoms, which were divided into five directions, and the middle of the formation also gathered from the runes into a flying sword phantom, which was five times larger than the five flying sword phantoms around!

This is the formation of the flying sword of the sacrifice and mother.

Xia Yin raised his hand and shot out five flying swords that had already been refined from the phantom of the scabbard of the first formation!

These five flying swords slowly flew into the formation of the Sacrifice Mother Flying Sword, and were directly embedded in the sword shadow of the five runes derived from the formation......

The faces of Xia Yin and Zhang Rouran instantly became solemn.

The two of them pinched the trick and chanted the spell at the same time!

Zhang Rouran took the lead in shooting out runes one after another, integrating them into the formation, making the formation glow bloom and run rapidly.

Xia Yin, on the other hand, shot different runes at the five flying swords......

The two cooperated with each other, Zhang Rouran was responsible for running the big array, and Xia Yin was responsible for the most important Five Swords Molecular Mother Sacrifice Ceremony, and finally the son and mother were integrated......

An hour later, the flying swords that were divided into five directions began to absorb the runic sword shadows that enveloped them.

Zhang Rouran, who was opposite Xia Yin, lost no time in shooting into the formation with several consecutive spells......

Buzz Buzz ......

The formation roared violently again.

In the next moment, the five flying swords that had absorbed the rune sword shadow gradually slowly converged towards the center of the formation......

After a while, the five flying swords with runes in circulation finally slowly converged, forming a thick rune light and began to spin rapidly!

The light became brighter and brighter, more and more dazzling, and finally Zhang Rouran and Xia Yin couldn't look directly, so they had to turn their heads sideways to avoid ......

After about half a burnt of incense, the light suddenly disappeared!

The two of them hurriedly turned around and looked into the formation, their faces full of nervousness!

I saw that in the formation, only one of the original six flying swords remained, quietly suspended.

Zhang Rouran's face was overjoyed, and then he moved towards the flying sword void......

With a bang, this flying sword shook suddenly, and four other identical flying swords were instantly derived.

Five flying swords lined up in the air, exuding a sharp aura that cuts through everything!

"Hehe, the first Zimu Flying Sword Sacrifice is perfect!"

Zhang Rouran cheered excitedly.

Xia Yin also looked at the girl, and the two, who had barely spoken and communicated for a long time, couldn't help but smile at each other.

"The first step is perfect, but next, you have to refine the other flying swords according to the number of five or five, and then fuse!"

Zhang Rouran nodded: "Well, as long as the first sacrifice is successful, it means that there is no problem with the formation, and then you only need to repeat the steps just now, and there will be no problem!"

Xia Yin nodded slightly, the mana in his body surged, and he raised his hand towards the five flying swords in the middle of the formation.

An invisible traction took the five flying swords over, suspended in front of Xia Yin, and merged the five swords into one, turning into a flying sword that exuded a sharp cutting aura.

Xia Yin put the flying sword into his palm and couldn't help but smile.

Next, you only need to take the other one hundred and twenty flying swords according to the method of sacrifice and refining just now, and you will get twenty-five flying swords that are fused with five or five, and then twenty-five will be fused again to become five, and finally the five will also be fused at one time and turned into a metal natal flying sword......

Once you have cultivated two and four attribute natal flying swords in the future, you will be able to cast the small five-element sword formation.

If the other four attribute flying swords are also like metallic flying swords, they can be born five or five in a row, turning into one hundred and twenty-five, if there are enough of them, and their spiritual power is strong enough, they can also cast the middle five elements sword formation, or even the big five elements sword formation......

Xia Yin's heart couldn't help but surge with excitement.

What a terrifying power it would be on the day when the Great Five Elements Sword Formation was unleashed!

Not to mention anything else, just the sharp cutting of this metallic natal flying sword, coupled with the magical effect of being able to escape into the void, almost no one can stop it!

At that time, he should have enough strength to go to the Great Ming Domain and take back his sister Youyou......

Xia Yin couldn't help but have a cold smile on his face!

The reason why he decided to sacrifice such a terrifying amount of metallic natal flying swords was because he had great ambitions.

His goal is to one day be able to kill the Daming Domain and recapture his sister Youyou.

But in the face of a behemoth like the Jiang family in the Great Ming Domain, if you want to crush them in terms of strength, casting the Great Five Elements Sword Formation is just the minimum requirement!

Because only by casting the Great Five Elements Sword Formation can you have the strength to confront the Jiang family, and even such strength may not be enough......

This is his goal, to be able to use the Great Five Elements Sword Formation one day, and this is only the minimum goal!

The ultimate goal is to cultivate the two layers of Tianyan Five Elements Sword Technique that have not yet been deciphered above the Great Five Elements Sword Array.

When the Tianyan Five Elements Sword Technique appeared on the yellowed ancient books, in addition to the beginner-level exercises being ordinary words, the other middle-level and high-level two-layer exercises were some mysterious runes, and they could not be comprehended for the time being.

However, Xia Yin was not in a hurry, after all, the beginner-level Tianyan Five Elements Sword Technique included the Small Five Elements Sword Formation, the Middle Five Elements Sword Formation and the Great Five Elements Sword Formation, which was enough for him to cultivate for a long time......

And the reason why he cultivated such a terrifying amount of terrifying metal natal flying swords at one time was to prepare for the mid-level and high-level sword tricks recorded in the mysterious runes!

Since it is a sword trick, and it is known as Tianyan, it naturally needs a large number of natal flying swords, and in the case of not knowing how many natal flying swords are needed, of course, it is safe to practice more!

Anyway, if it is refined, it doesn't matter if it is not used at that time, more than a hundred flying swords are directly fused into one sword, which can also increase the power......

"Xia Yin, what are you doing in a daze!"

Zhang Rouran's angry voice pulled Xia Yin back to reality from his distraction.

Xia Yin couldn't help but slap himself with his backhand: "At such an important moment, what am I thinking about?

Shaking his head vigorously to dispel all distractions, a look of determination resurfaced in Xia Yin's eyes.

"Rouran, activate the Zimu Flying Sword Sacrifice Formation again!"

As soon as Xia Yin's words fell, Zhang Rouran had already shot into the formation that had just stopped......

Buzz.

The formation worked again, and then countless runes evolved out, reforming the rune sword shadow.

It is also a five-way rune sword shadow, arranged according to a mysterious trajectory......

Seeing this scene, Xia Yin's face showed a touch of excitement, and then the scabbard of the large array on the other side was lightly clicked, and five flying swords slowly flew towards the formation, embedded in the Wu Dao rune sword shadow......

This is the sacrifice of the flying sword of the son and mother.

First of all, five flying swords were sacrificed, and finally five sons became one mother.

One hundred and twenty-five flying swords, divided into twenty-five groups, were practiced in turns, and finally five or five were in one.

The second step is to divide the twenty-five flying swords after the five-five into one again, and once again refine and fuse.

When the twenty-five flying swords are fused into five, the third step is to fuse the five flying swords again into one......

After the more than 100 flying swords are refined, they will eventually all be fused into one "Ultimate Mother Sword".

This flying sword contains the power of one hundred and twenty-five flying swords, which can be called terrifying!

After such a cycle of sacrifice, the flying sword can be continuously reborn in five or five with a chain of children and mothers with the same root and origin, one into five, then into twenty-five, and then one hundred and twenty-five......

Within the formation, the five flying swords had already begun to absorb the rune sword shadows......

Zhang Rouran once again lost no time in playing a legal duel!

The five flying swords began to converge towards the center of the formation, slowly merging into a ball, beginning to shine with rich light, and spun rapidly......

When the light lurked again, there was only one flying sword left in the formation!

Xia Yin was not surprised by this at all.

Yao Yao pointed out, and the flying swords in the suspended formation trembled suddenly, and then four other identical flying swords were derived, and they flew out of the formation one after another under Xia Yin's outstretched hand......

When these flying swords were in the air, they automatically turned into a flying sword and fell into Xia Yin's hands, exactly the same as the flying swords that were refined for the first time......
