With the entry of the Phantom Yin Sword, a strong icy cold aura instantly diffused, wrapping the sword body tightly, and confronting the flames in the ding, the constant conflict between the two erupted into an extremely terrifying fluctuation.

After a while, cracks were shaken out of the surrounding mountain walls one after another, and rocks flew sideways.

Ning Bufan gritted his teeth and controlled the balance between the two sides, although the melted spirit stone essence in the ding at this moment could be refined into a spirit weapon-level existence, but after all, it had not yet formed an instrument spirit, and it could not compete with the sword spirit of the Phantom Yin Sword.

And the Phantom Yin Sword faced the raging flames in the ding, and the heat that continued to invade the cave, it also struggled to resist, the sword body roared, and one after another strong cold currents spread.

In an instant, hot and cold alternated, and it was as if there had been an explosion in the ding.

The phantom's face was full of horror at this moment, and his eyes were full of surprise as he watched the fluctuations in the Fulong Ding.

After a while, he suddenly said to himself: "This Ding ...... I'm afraid that even if it is placed in the imperial capital, this is one of the best refining gods!"

"What is the origin of this young man, and he has so many treasures...... Listening to his tone, it seems to be someone nearby, this was just a village back then, I don't remember any prominent families here?"

The phantom frowned and thought for a moment, but he couldn't figure it out, he carefully recalled the various families in the imperial capital during his lifetime, and he couldn't find anyone who could correspond to the young man in front of him.

"That's it......" The phantom suddenly smiled self-deprecatingly, and said, "I've been dead for a hundred years, so why bother with this?"

"However, I have never heard of daring to fuse two spiritual weapons to refine them before, and I don't know if this kid is really bold or a little dependent. ”

The phantom looked at Ning Bufan without blinking, and suddenly reminded: "Boy, if you continue to stalemate like this, the power of these spirit weapons will burst out and eat you, you might as well try to integrate the essence of the spirit stone in the ding into your sword." ”

At this moment, the aura in Ning Bufan's whole body was mobilized, turning into a long river of spiritual power that shrouded Fu Long Ding, suppressing the power of the impact.

After listening to the reminder of the seniors, he suddenly realized, and hurriedly sensed the Phantom Yin Sword and suspended it in the center of the Ding, at this time, a layer of cold ice aura was condensed around the sword body, trying to isolate the frenzied flames outside.

Ning Bufan's body was shocked, and he approached the Phantom Yin Sword with the essence of the spirit stone fused with the Red Dragon Crystal, and the essence of the Red Flame Dragon sensed this force that was clashing with it, and immediately let out a violent roar, and the fierce aura slashed towards the Phantom Yin Sword.

"What ......"

The Phantom Yin Sword is just a high-level magic weapon, but the essence of this spirit stone is already close to the embryo of the spirit weapon, if the two fight head-on, I am afraid that both will lose.

Ning Bufan was about to stop it, but he heard his predecessor shouting: "Don't move, look at ...... first"

Ning Bufan was surprised, but as a fourth-grade refiner, his predecessor was far superior to him in terms of knowledge and cultivation, and he stopped at the moment, and watched with some distress as the essence of the spirit stone turned into a sharp edge, directly breaking through the aura cover of the Phantom Yin Sword, and then slammed into the sword blade.

Bite......

A shrill sound rang out, and the entire Fulong Ding trembled violently, and countless cracks instantly spread from the stone under the Ding, like a black earth dragon swimming.

Ning Bufan opened his eyes wide and looked over, and saw that a gap was directly cut out of the tough ice edge of the Phantom Yin Sword, and the originally perfect sword body was flawed, and the sword spirit suddenly screamed bitterly.

This Phantom Yin Sword was refined by Ning Bufan and Master Gongye before, and his soul mark was added, in a sense, just like his child.

At this moment, the sword body was so seriously injured, even Ning Bufan's soul was in severe pain, as if the sharp edge of the spirit stone essence had struck his body.

However, at this moment, the attack of the spirit stone essence was not over, and the dragon-like embryo was like crazy, attacking violently.

One after another, the sharp qi blades slammed into the Phantom Yin Sword, and the gap became bigger and bigger, and gradually, the Illusory Yin Sword, which was originally awe-inspiring, gradually withered.

"Boy, since your cultivation is not enough to stimulate a powerful enough water spirit, why don't you use this sword to refine the essence of this spirit stone and give it a try?" the senior said when he saw this, and there was a hint of excitement in his tone.

Because he really saw a trace of the possibility of the fusion of the two spiritual weapons in Fulongding, which was equivalent to the souls of two people completely together, unbelievable and unheard of.

Ning Bufan's heart jumped when he heard this, and he also felt incredible, but now, there is no other way.

He used his aura to completely withdraw the sword qi defense of the Phantom Yin Sword, and then the Red Flame Dragon flew in the flames, rushing towards the Phantom Yin Sword with a devastating momentum, looking at its posture, and even wanted to directly destroy the magic weapon in front of him.

"I didn't expect this beast to be so rampant after it died?"

Ning Bufan was secretly surprised, this Red Flame Jiaolong was completely transformed after the Red Dragon Crystal entered the essence of the spirit stone, and the remnant soul and berserk factor of the Jiaolong had been completely eliminated, but he didn't expect it to still have a trace of anger.

"I don't believe I can't surrender you after you're dead?"

"Phantom Yin Sword Qi, out!"

Ning Bufan let out a loud shout, and the Phantom Yin Sword seemed to wake up quickly from its malaise under his urging, and then turned into a cold air current, completely enveloping the Jiaolong that came over.

At this moment, the Red Flame Jiaolong seemed to be trapped in an enchantment, roaring angrily, constantly struggling to break out.

But at this time, Ning Bufan was in the same camp as the Phantom Yin Sword, and the powerful aura turned into a cold current, which continuously compressed the momentum of the dragon, and gradually, the essence of the spirit stone in the shape of the dragon gradually lost its majesty, and let out a low whimper.

"Boy, quick, take this opportunity to refine and fuse them!"

Listening to this extremely bold suggestion, Ning Bufan couldn't help but become short of breath, he completely released his soul power and swept towards Jiaolong.

Gradually, this disadvantaged dragon gradually became obedient under the suppression of Ning Bufan's soul, because it also felt that only by succumbing to Ning Bufan could it survive.

At the moment when the soul imprint was completed, a wonderful scene appeared in Ning Bufan's sea of consciousness, an ice-blue sword spirit and a crimson dragon slowly emerged, the two were completely different, but because they were all connected to his soul, a kind of aura of the same origin was generated.

In the next step, there was no need for Ning Bufan to manipulate it, the Jiaolong had already taken the initiative to approach the Phantom Yin Sword.

It's just that this time it didn't attack with hostility, but slowly used its own spirit stone essence to repair the gap in the Phantom Yin Sword, and the two gradually merged together, not distinguishing each other.

The phantom looked at this scene in amazement, and the expression on his face was very strange.

After a while, he looked up to the sky and sighed: "In vain, I am still a fourth-grade refiner of the empire, and I didn't know until after my death that different spiritual weapons could be fused with each other. ”

He cried and laughed, not knowing whether to rejoice or be sad.

As the fusion process of the Phantom Yin Sword and the Jiaolong continued, a strange wave also spread out, shaking everything around it. This time the fluctuations were not as strong as before, but they were more powerful.

Quietly, Ning Bufan was shocked to find that around the body of the ding, countless stones were shocked into powder, and even the body of the ding sank a few feet, and there were fine stone chips all around.

And he sensed towards the Ding again, and found that at this moment, the essence of the spirit stone had completely repaired the Phantom Yin Sword, and at this moment, the ice-blue sword body also faintly revealed a red aura, and then looked carefully, and actually saw that there was a shadow of a dragon faintly in the center of the sword body, wandering in it, flickering.

After this change, the power of the Phantom Yin Sword skyrocketed again, completely surpassing the previous level.

"Boy, this is already a low-grade spiritual weapon. However, with the power of the Red Dragon Crystal and the Spirit Stone, this sword should be far more than that, but your comprehension of alchemy is still too low, so there is no way to complete it completely, and when you reach that realm in the future, you may be able to raise this sword to the intermediate level, or even the level of a high-level spirit weapon. ”

Ning Bufan nodded, he was already quite satisfied at the moment. And after this refining, he was pleasantly surprised to find that his soul power was a little stronger, and he even felt that he had faintly touched the threshold of a second-grade refiner.

And the current Gongye master, that is, the second-grade refiner, if he knew that Ning Bufan only spent more than half a year to complete his achievements in the previous years, I don't know what he would be surprised about?

"Boy, it's been reborn, it's very different from before, and it's time for a different name. ”

Ning Bufan thought for a moment, and suddenly said, "Let's call it the Phantom Yin Dragon!"

"Phantom Yin Dragon Sword, good name!"

The senior smiled and nodded, and sighed, then he looked at the sword body staring at the Fulong Ding, and said, "With this low-level spiritual weapon alone, I'm afraid it may not be able to break the volcano, so I'll give you another spiritual trick......"

"Spirit...... Spiritual Formula?!" Ning Bufan was stunned when he heard this, the spiritual technique is extremely precious, it is a more advanced way to use spiritual energy than the Method, and its power is far beyond the Sect and can be compared to the Sect.

Even in the entire Wuyang City, almost no one had ever seen the shadow of the Spirit Technique. Ning Bufan had heard before that there seemed to be a scroll of spiritual recipes hidden in the Qi clan, but it had never been shown in front of outsiders.

And at this moment, as soon as the senior said casually, he was going to give him a scroll of spiritual formula? Ning Bufan was extremely surprised in his heart, and his breathing was a little unsmooth.

"This spirit trick combined with the Phantom Yin Dragon Sword should be able to barely break the volcano. ”

"Boy, pick it up!"

Ning Bufan took a step forward excitedly, only to see the phantom casually sending out a spiritual light, and slowly entered his sea of consciousness.

In an instant, several big characters emerged, vigorous and powerful, and elegant, as if a spiritual light flew through the sky.

"Wind and Cloud Fantasy Sword Technique!"
