"Perhaps, ordinary dark iron really can't withstand the crossing spirit, but if you add this, it's not just an ordinary piece of dark iron. ”

The words fell, Long Yufeng took out a piece of white spar with a hint of red in the ring, and threw it into the furnace, and then with a movement of his mind, the flames began to burn wildly, and when he saw this, he asked puzzledly:

"What are you singing again, your refining technique is unheard of by the old man, with all the bells and whistles, hum!"

Long Yufeng said with a smile:

"This spar is called Radu molybdenum, which is composed of three substances, which can better remove impurities from the black iron, and can also greatly improve the hardness and toughness of the black iron, in a distant place, they call him a high-density alloy. ”

When Long Yufeng said this, a blue planet and a group of lovely people on that planet appeared in his mind, and a touch of nostalgia appeared on his face.

When Long Batian heard this, he was confused, and said with a laugh:

"All the bells and whistles, anyway, the old man doesn't understand, just don't waste the materials, hahaha......"

At this moment, Long Yufeng took out a small piece of pale cyan spar from the ring, threw it into the furnace, urged the formation again, and continued to refine, although Long Batian was puzzled, he couldn't help but ask curiously:

"What is this, and what does it do?"

Long Yufeng said with a smile:

"This spar is called the Outer Heaven Meteorite, yes has the name of white copper iron crystal, adding to it, can make the weapon harder and tougher, look more smooth and beautiful, and can also magnetize it to a certain extent, fighting, can play a role in interfering with the enemy's weapons. ”

At this moment, Long Batian was even more confused, and Long Batian was also interested in this little apprentice, and watched it attentively.

I saw that after the light cyan spar entered the furnace, it released a light cyan light and quickly integrated into other materials, and the color of the material gradually added a touch of light cyan, and wisps of black gas emanated from the smelting material.

It wasn't until the black qi completely disappeared and a faint aura appeared on the surface of the material that Long Yufeng smiled and said:

"It's time, ......"

Long Yufeng's hands quickly pinched, and the array patterns kept flickering, and with the continuous flickering of the formations, the surrounding aura began to become active, and the surging soul power of Long Yufeng was released, and the surrounding rich aura was quickly condensed into the furnace with the assistance of the formation.

Then, in his mind, the pictures of crossing the spirit quickly flashed, and with the change of the dragon wind technique, a long sword in the furnace slowly condensed and formed, and the surging spiritual energy poured into the long sword, and the sword body trembled, emitting a sharp sword groan.

At the same time, a wave of energy, centered on the furnace, quickly spread out to the surroundings, stirring up ripples, but the magic of the dragon wind did not stop, seven seven forty-nine main formations, plus nine hundred and eighty-one auxiliary formations, all lit up, forming a large cylinder, the dragon wind and the dragon overlord submerged into it, from a distance, all kinds of formations, gorgeous and colorful, extremely spectacular.

The fateful monk and the broken sword people who had just finished alchemy were all surprised when they saw this formation, and they all gathered around, and everyone talked and said:

"I don't know what the hell this Senior Brother Long is doing!"

"That's it, this old guy, just a soul clone, dares to make such a big battle. ”

"You say this old ghost can't be refining artifacts, right?"

"It's unlikely, Senior Brother Long has suffered a great loss in cultivation since the Great War, even if it is a true body, refining the artifact is probably extremely reluctant. ”

"Then this is ......"

......

Everyone can only speculate blindly outside, and they can't see the current situation inside clearly, this is the critical moment of refining, and they can't rush into the battle.

The big man in the formation who is full of dragon and wind, it seems that with his current strength, refining such a treasure is really reluctant, if it is not for the assistance of the Hongmeng Seventy-Nine Melting Formation, Long Yufeng will definitely not be able to refine it.

Finally, the surrounding aura stopped restless, only to see that above the sword body in the furnace, the aura overflowed, and from a distance, in the raging fire, like a faint purple mist, Long Yufeng wiped the beads of sweat on his forehead, and said excitedly:

"I succeeded, and the apprentice succeeded......"

Seeing the success of Long Yufeng's crossing of the spirit, Long Batian's face was full of surprise, but more of a relief, I didn't expect that an ordinary piece of dark iron was really succeeded by this kid to cross the spirit, it was really amazing, listening to what Long Yufeng said, Long Batian laughed and said:

"See! see...... As a teacher and not blind, hahaha......"

Long Batian smiled contentedly, but just when Long Batian felt that Long Yufeng should close the furnace, he saw Long Yufeng say seriously:

"There are two last steps, and you're done. ”

Seeing Long Yufeng's confident appearance, Long Batian whispered suspiciously:

"What kind of moth is this little rabbit going to do......"

At this moment, I saw Long Yufeng's whole body flashing with thunder, and the sound of crackling thunder and lightning echoed in the sky, and Long Yufeng shouted loudly: "Magnetize, go to ......"

The sound of electricity fell from the shouting, accompanied by the violent thunder and lightning, wrapping the long sword, under the action of the strong current, the magnetic properties of the meteorite crystal outside the sky in the long sword were completely activated and strengthened, and the surface of the long sword flashed with a thunder arc.

Seeing that the magnetization was about to end, Long Yufeng opened his eyes violently, and at the same time, his hands quickly pinched, and then shouted loudly: "Star Ancient Array, knot ......"

When Long Batian heard this, his eyes were like frogs, and he scolded incredibly:

"Stinky boy, are you crazy, do you plan to attach a formation pattern to a piece of mortal iron? The old man heard me right, your success in crossing the spirit is also a fluke, you... This ......"

Longba's weather is not good, he is speechless for a while, he can't speak, isn't a good spiritual weapon fragrant?

At this moment, the Hongmeng Seventy-Nine Melting Casting Formation, with the urging of the Dragon Imperial Wind, flashed dazzling light again, and a sub-formation like a miniature small universe was born under the urging of the Hongmeng Seventy-Nine Melting Casting Formation.

The stars shimmered with a little starlight, along a special trajectory, constantly rotating, and finally under the effect of the main formation, the star ancient array turned into a slender cone, and slowly merged into the long sword.

Under the effect of the powerful soul power of the dragon wind, the Star Ancient Array was being carved onto the sword body with a special trajectory, and finally it was like a galaxy showing above the sword body.

Looking at this scene, Long Batian was stunned, his eyes were as wide as a frog, staring straight at the smelting furnace, slowly perfecting the formation, not even daring to blink his eyes, for fear that he would miss any details, and his mouth was slightly open and he couldn't say a word.

As the refining came to an end, the melting formation gradually dispersed, leaving only a few auxiliary formations, still flickering, and the people outside the formation were curiously saying, "Senior Brother Long, you ...... again"

However, before he finished speaking, he was stunned by the scene in front of him, what the hell are you doing, Senior Brother Long?

What appeared in front of them was Long Batian, who was shocked, and Long Yufeng, who was concentrating on refining.

An incredible thought flashed through everyone's minds, could it be that the scene just now was made by a hairy boy who had stepped into the refining process for less than a year?

But with such a big movement just now, even if you think about it with your knees, it can't be made by a kid who stepped into the refining weapon and was less than a month old, but what is the explanation for the scene in front of you?

However, Long Yufeng, who was concentrating on refining the weapon, didn't notice all this, beads of sweat the size of beans kept dripping from his forehead, this was the last moment, he had to be a thousand times more careful, and he couldn't fall short.

Long Yufeng's face condensed, and a drop of essence blood was forced out, turning into bursts of blood mist, wrapping the long sword, Long Yufeng's physique was special, and the blood was naturally unusual.

With the blood of the dragon and the wind as the guide, the ancient array of stars is perfectly embedded in the long sword, and a burst of stars flicker on the sword body, shining with stars, and the whole long sword is like a bright galaxy.

Gradually, the long sword became more convergent under the wrapping of blood mist, and the dazzling light was restrained in it, and at this moment, Long Yufeng shouted: "It's done, close the ......"

Together, the long sword broke out of the furnace, Long Yufeng dodged, caught the long sword, the long sword was simple and ordinary, and there was nothing peculiar about the appearance.

However, when I started, I felt very kind, Long Yufeng had an electromagnetic hover, soaring into the air, and the power of the stars was injected into it, under the urging of the power of the stars, the light of the sword body flickered, the whole body was blue, and the stars were twinkling, like a galaxy.

Long Yufeng struggled to swing out a sword, and a sword light like a galaxy in the sky flashed by, attacking the surface of the lake, only to hear a loud bang, stirring up a splash.

Seeing this, the Tyrant Dragon Venerable and the others were surprised, and the Tyrant Dragon Venerable couldn't understand how this mere piece of mortal iron could refine such an excellent weapon.

Long Yufeng fell in front of Long Batian, and in Long Batian's surprised gaze, he presented the long sword in his hand, and asked with a smile:

"How's that?

Long Batian took the long sword and looked at it carefully, the sword body was simple and unremarkable, and from the appearance of a single bush, it looked like a mortal weapon, but the texture of the sword body was delicate, and when he urged the power of the stars in his body, he could feel the surging energy in the long sword.

Long Batian, who was watching, nodded again and again, and said with a smile:

"Wonderful, at least it can be ranked into the middle grade spirit weapon, in terms of power alone, it is not even inferior to the top grade spirit weapon, good boy, it seems that the old man has seen you first. ”

Long Batian patted Long Yufeng's shoulder and laughed and said:

"It's not my apprentice of Long Batian, hahaha......"

At this time, Long Batian was like a father whose child suddenly achieved good grades, his eyes were full of happiness, everyone couldn't help but laugh when they saw this, Long Batian asked curiously:

"Boy, what are you going to give this sword a name?"

When Long Yufeng heard this, he fell into deep thought, and after a while, he said with a smile:

"Since there is a Star Ancient Array, why don't you call it the Star Sword!"
