In the stone cave deep underground, an angry roar echoed and stirred, and the whole cave shook incessantly, and even pieces of rubble rolled down.

And in such an environment, the sky wolf was not chaotic at all, sitting cross-legged with a calm face, his right hand penetrating the firelight, dancing into a phantom in front of him, and constantly burning the mysterious array patterns on the ice-blue blade.

And with the burning of the heavenly wolf, on the ice-blue crystal blade, seven points of light lined up into a Beidou, shining more and more.

And between the seven star points, there are dozens of vertical and horizontal veins, with the seven star points as the center, radiating along the complex trajectory, connecting the seven star points with each other. Form a rather mysterious seven-star array!

And at this moment, the right hand of the Heavenly Wolf dancing into the wind suddenly condensed, and thousands of phantoms instantly became one, condensed into a finger, and hit the Tianshu Star heavily!

As the Heavenly Wolf's finger fell, the bright silver spiritual power of the Xuanxing Immortal Jue, which was full of starry radiance, spurted wildly, penetrating into the Tianshu Star, and the entire formation suddenly dimmed, only the Tianshu Star was bright.

But the fingers of the Heavenly Wolf did not stop, they were heavily placed on the blade, maintaining the infusion of spiritual power, moving slowly but firmly, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, and slid in turn, and finally froze on the shaking light!

And as the fingertips of the wolf slid by, not only the seven stars lit up in turn, but even the trajectory was also shining with a crystal texture, connecting into a line, running through the seven star points together!

And when the wolf's fingers finally froze in Yaoguang, all the textures on the entire blade suddenly shone, and a dazzling silver light burst out, suppressing the blue light and purple flames.

But the silver light only lasted for a moment, and then it dimmed, the light on the blade dimmed, and all the textures converged, only seven faint star-like dark lines faintly appeared on the blade.

And after burning the formation pattern, the sky wolf seemed to have consumed a lot of spiritual power, his face turned slightly pale, and he hurriedly took out a pill and swallowed it before recovering.

Looking at the seven dim textures on the knife body, the Heavenly Wolf's eyes showed a look of joy, and the seven-star array diagram he had spent so much effort burning, although it was only a base map, it was by no means idle.

Because the Star Knife Blood Knife is now approaching and can't keep up with its own usage requirements, Sky Wolf fully took into account its growth when refining this knife!

The seven star points of this seven-star array are not only the root of the array, but also have an inlay effect, which can be inlaid with items such as fusion crystals to increase the power.

And what Sky Wolf planned was to embed the magic core of an ice-based fourth-order demonic beast for these seven star points. In this way, it can not only provide sufficient spiritual power for the rotation of the formation, but also increase the entire long knife!

When the seven stars are complete, the quality of this long knife will definitely be drastically improved compared to now, even if it is used to transform the gods, there is no problem!

And just when the seven-star array was finally completed, the entire stone cave suddenly shook, and large pieces of rubble fell down. The angry roar became clearer and clearer, and even above the two knife cuts on the cave wall, red flames began to flow.

This means that the Fire Cloud Leopard is already very close to here, and it may even break through at any time!

Even, the sky wolf had already felt the unique ferocious aura of that fierce beast, and his eyes suddenly turned cold, looking up at the top of his head, and the killing intent surging in his eyes.

Leng Leng retracted his gaze, the light in the hand of the Sky Wolf flashed, and two round magic cores with dense cold air came out, one of them was naturally the magic core of the Ice Blade Mantis, and the other was the ice type demon core obtained by the Sky Wolf killing an ice bear a few months ago.

After taking out the demon core, the Sky Wolf did not hesitate to slap the ice bear demon core on the Tianshu starpoint.

The Ice Bear Demon Core suddenly flashed with light, and when it didn't enter, the Tianshu Star Light suddenly shone brightly, and it could be clearly seen that a round bead was embedded in the ice-blue blade.

Streams of abundant spiritual power filled with an icy aura rippled out from the Ice Bear Demon Core, making the Seven Star Formation and the veins and textures of the blade itself shine one after another, and slowly return to calm, but it makes the breath of the entire long knife even colder!

Seeing that embedding a magic core really produced a huge amplification effect, the wolf's eyes couldn't help but show joy, but he didn't embed the ice blade mantis's magic core into the blade.

Because, this magic core is still very useful!

A fine light flashed in the wolf's eyes, and he directly pressed the demon core in his hand towards the end of the long knife hilt.

The demon core fell on the hilt, and suddenly a blue light flashed, just like the previous ice bear demon core, directly submerged into it, and a wave of ice blue light suddenly shone from the hilt, quickly spreading over the entire knife body, making the entire long knife clang, and the chill surged!

The sky wolf did not leave an inlay space on the handle of this knife, but this magic core was still submerged in this way, and it was so natural that it was not entered, even more perfect than the fusion of the ice bear demon core.

Because, it is the magic core of the ice blade mantis! He and this long knife are one! At this time, it is like a natural fusion!

The moment the demon core was integrated into the hilt, the light in the wolf's eyes flashed, and with a wave of his hand, he directly removed the purple pole demon fire!

The Purple Pole Demon Fire disappeared suddenly, but this cave mansion did not fall into darkness, and a clear blue light illuminated the entire cave mansion.

For the first time, this long sword of ice and snow smelted from the flames broke away from the embrace of the flames and was exposed to the air, and the soft ice blue light poured down, making the entire cave seem to fall into a dream!

The cold air around the blade was thick, the blue light flowed, and a cold chill came out, and the cave wall was suddenly covered with a layer of frost!

Looking at this ice-blue long knife floating quietly in the air, like a dream, the Sky Wolf nodded slowly.

However, although he had already removed the Purple Pole Demon Fire, the sacrifice of this sword was not over yet!

Because, it doesn't have a soul of its own!

A magic weapon, only with its own soul, can it be regarded as a real spiritual treasure!

Even if it is of the same level, there is no magic weapon without a soul, and there is no comparison between a magic weapon with a soul!

Because there is no magic weapon of the soul, it is just a dead thing, and after having the soul, this magic weapon is equivalent to having spirituality, not only can the potential of the magic weapon be maximized, but even attack and defend independently without the control of the monk!

Since the Heavenly Wolf has cultivated, he has never possessed a magic weapon with a soul, and with his refining attainments, it is not enough to give a soul to a magic weapon in the infancy.

However, he was sure that he could make the knife in front of him have his own soul! Because, he had the beast soul of the Ice Blade Mantis!

With a casual move, the sky wolf directly took out the Hundred Beast Compass, and casually took a little on one of the shining seals that revealed an ice blue light, and led it outward, and suddenly an illusory soul shadow with a blue body was attracted out.

It is the beast soul of the Ice Blade Mantis!

After the beast soul appeared, it was at first at a loss, but immediately it trembled, and suddenly turned around, looking at the ice-blue long knife that was hanging in the air, floating and sinking, emitting bursts of cold air, and suddenly let out a strange soul roar.

The sky wolf's eyes flashed, and his right hand pinched out a strange seal, which landed on the eyebrows of the ice blade mantis beast soul without hesitation, forming a mysterious rune imprint.

Immediately afterward, he took out an identical seal, and without hesitation, printed it on the magic core embedded in the hilt.

After it was completed, the sky wolf did not hesitate, the index finger and middle finger of his right hand were put together into a sword, and he hung in front of the rune above the demon core, and frantically infused the spiritual power of his whole body, while his lips were buzzing, and he quickly recited inexplicable incantations.

Stimulated by spiritual power and spells, the mystical runes above the demon core suddenly shone brightly!

At the same moment, the runes in the eyebrows of the mantis beast soul also shone brightly, and an inexplicable force appeared instantly, and the mantis beast soul was stunned at first, and then hissed, directly turning into a blue streamer, and directly rushed into the demon core.

And as the soul shadow rushed in, the inscription on the demon core suddenly shone brightly, and the face of the heavenly wolf also showed a hint of joy.

That's right, the Heavenly Wolf's refining attainments are indeed not good, what he used before was just the simplest talisman seal of condensing the soul of the instrument, even if it was supported by the spiritual power of the Yuan Infant Stage, at most, it could only barely pull the weak souls of the foundation building period and turn them into instrument souls.

But it was with such an ordinary spirit guide that Sky Wolf successfully introduced the beast soul of the fourth-order Ice Blade Mantis into the long knife, not because of anything else, but because this knife was completely refined using the body of the Ice Blade Mantis, and it was fused with the magic core, and the beast soul of the Ice Blade Mantis itself was one!

There is always the closest connection between the soul and the body. Even without the traction of the Sky Wolf, the beast soul of the Ice Blade Mantis was also close to this long knife at the first time, and hated to cling to it.

And with the spiritual traction of the heavenly wolf, all this is a matter of course, and the ice blade mantis did not resist at all, and integrated into the long knife. Even the fusion process that originally took a while was directly saved, and the mantis knife soul instantly fit perfectly with the long knife itself.

And in the short time that the ice blade was given the soul, the vibration in the stone cave had become stronger and stronger, and the falling rocks were like rain, and the roar of the fire cloud leopard was like a whisper, almost penetrating in!

With the integration of the soul of the instrument, the ice and snow long knife suddenly trembled, and a praying mantis phantom appeared, and the light on the entire blade suddenly brightened, emitting a clear knife sound, shaking through countless falling gravel, and it actually rose directly into the sky, about to penetrate the rock formation.

The biggest difference between the magic weapon of having a machine spirit and the ordinary magic weapon is that it has its own spirituality, and it can even be said that it has a certain consciousness and can act independently to a certain extent.

Ordinary spiritual weapons have just been refined, and they will have a good impression of their master, and it is easy to recognize the master, but the one that the wolf has refined now, its spirit is an ice knife mantis, and it is an existence that was killed by the wolf himself!

Although the soul is ignorant at this time, and he has forgotten the things before his death, he can also instinctively fear and dislike the wolf, and it is strange that he can have a good impression. Therefore, as soon as it was integrated into the blade, the beast soul of the ice blade mantis directly controlled the long knife and soared into the sky, trying to escape.

How can you let the magic weapon that you have worked so hard to refine escape?!

The wolf's eyes were cold, he snorted coldly, without the slightest hesitation, at the moment when the long knife flew up, he exerted force under his feet, rose up, and almost turned into an afterimage, and his right hand suddenly poked out like lightning, and grasped the handle of the ice blade!

The ice blade was in his hand, and a bone-chilling chill poured in instantly, and with a click, a layer of crystal blue cold frost froze up frantically along the right arm of the wolf, and in an instant, it covered the entire right arm, and under the infusion of cold and cold air, the blood all over his body was almost coagulated!

The wolf himself didn't expect that this knife could have such power, and his faintly blue face suddenly changed, but there was a hint of excitement in his eyes - the stronger this knife, the more excited he was!

Grabbing the frost and falling to the ground, the light in the wolf's eyes was bright, and he shouted, the spiritual power of his whole body ran wildly, and his right arm shook, directly shattering the frost countless times, and constantly sending strands of majestic spiritual power into the ice blade, suppressing it strongly!

And at this moment, a crazy roar came from overhead, and the rock on the top of the cave shattered!

In the midst of the countless huge mountain rocks splashing and falling, a hideous demon leopard with crimson flames burning all over its body roared wildly, shattering countless splashing rocks, and directly pounced on the sky wolf standing in the hole, suppressing the ice blades with all his might!
