In the secret room, Xia Yin and Zhang Rouran sat opposite each other, and the Celestial Star Meteorite was suspended between the two.

A small firebird spat out of Xia Yin's mouth and shot at the Celestial Star Meteorite suspended in the air.

The firebird, which was originally half white and red, suddenly turned into a pale red flame and sprayed evenly on the Celestial Star Meteorite, completely enveloping this meteorite......

The sacrificial Natal Flying Sword has finally begun.

Although the girl didn't understand why Xia Yin went crazy and wanted to sacrifice a full one hundred and twenty-five metal natal flying swords, but under Xia Yin's smile and silence, the girl finally decided to help him complete it.

Time passes slowly......

The flame-wrapped Celestial Star Meteorite has been quietly suspended in the air.

This meteorite iron is known as the hardest of all the materials found in the Immortal Cultivation Realm so far, and it is not only difficult to destroy, but also difficult to refine!

Xia Yin once consulted the classics and learned that if the Celestial Star Meteorite was used with ordinary Danhuo, it could not be refined at all.

Even those powerful alien fires require decades of uninterrupted scorching to refine them.

It can be seen that this material deserves to be called the hardest!

Ten days have passed.

The flames in the air and the celestial meteorite still did not show the slightest change.

At this time, a spell suddenly sounded in Zhang Rouran's mouth, his hands pinched, and then he bent his fingers a little, and one after another runes came out of his hands, slowly flying towards the flame-wrapped Heavenly Star Meteorite, merging into it......

After cultivating to the Great Perfection of Foundation Building, Zhang Rouran's Void Spirit Body awakened many natural powers, including the special talent ability to refine various materials, which can smelt materials directly with runes without the need for flames.

These hundreds of runes just now are the strongest runes that the girl used to smelt materials.

However, the runes were integrated into the Celestial Star Meteorite, and there was still no change in the slightest!

If it was an ordinary material, whether it was Yuehua Jinyan or these runes, they could be easily smelted, but when these two strong smelting methods were combined, the Celestial Star Meteorite still did not change in the slightest......

The hardness of this material is incredible!

Of course, Xia Yin and Zhang Rouran had already prepared for this, the two looked at each other, Xia Yin drove Yuehua Jinyan to wrap the meteorite and continue refining, while Zhang Rouran sat cross-legged and began to meditate and cultivate......

Sacrificing hundreds of smelting runes at one time is a great consumption for the girl, and she must meditate and recover for a period of time before she can use the smelting runes again......

After another ten days, Zhang Rouran pinched the mantra again, shooting out hundreds of mysterious runes, fusing into the celestial meteorite suspended in the air......

In this way, while the two of them were cultivating, they controlled the Yuehua Jinyan smelting meteorite iron, and every ten days, Zhang Rouran sacrificed hundreds of smelting runes to assist Yuehua Jinyan in refining this piece of Celestial Star Meteorite......

A year passed quickly.

On this day, when Zhang Rouran once again sacrificed hundreds of runes and merged into the Celestial Star Meteorite suspended in the air, the meteorite, which had been motionless, began to redden slightly, and then the red gradually became thicker......

In the end, the entire Celestial Star Meteorite turned into a red, scorching iron lump!

"It's finally going to be done!"

Xia Yin and Zhang Rouran let out a cry of surprise at the same time.

In the past year, although the two of them have been cultivating, the refining meteorite has never stopped, making Yuehua Jinyan keep burning, and Zhang Rouran shoots out hundreds of smelting runes every ten days to assist in refining......

I have to say that the hardness of this celestial meteorite is unimaginable!

Yuehua Jinyan belongs to the rare heaven and earth fire.

And Zhang Rouran's smelting rune is the unique talent of the Void Spirit Body, which can be called nothing without melting!

However, it took a whole year for these two incomparably powerful smelting methods to melt the Celestial Star Meteorite.

Next, Xia Yin and Zhang Rouran pinched the mantra at the same time, and one after another, the magic was shot out one after another......

Xia Yin's law decision, the method of sacrificial refinement from the Tianyan Five Elements Sword Technique, must be performed without the slightest mistake, as for what the effect of these law decision spells, Xia Yin himself is not clear.

However, the runes that Zhang Rouran shot out were very different.

These runes are no longer smelting talismans, but special refining methods awakened by the girl's void spirit body, and the entire immortal cultivation world can be used by Zhang Rouran!

As the girl's runes shot into the big red and scorching iron lump in the air, gray impurities were squeezed out of the Celestial Star Meteorite.

The girl's runes, in addition to being able to remove impurities from the material, also have another part of the runes that have the effect of strengthening the hardness of the Celestial Star Meteorite.

For the metallic natal flying sword, Xia Yin has been very clear, and only pursues two effects - sharp and hard.

The sharpness attribute is unique to rotten silver essence, and Tianxing meteorite iron only needs to pursue the ultimate hardness.

Therefore, the girl deliberately incorporated the runes that strengthened the hardness of the Celestial Star Meteorite into it......

When the girl stopped pinching and chanting the mantra, Xia Yin's various legal decisions also stopped at the same time.

At this time, the red iron lump in the air has begun to gradually soften, and finally turns into a mass of red liquid, rolling around in the air......

"Alright, let's start dividing the sword blank!"

As soon as Zhang Rouran's words fell, I saw the girl raise her right hand, stretch out her index finger, and continue to pull towards the Celestial Star Meteorite Iron Liquid in the air......

Woohoo......

Yuehua Jinyan automatically peeled off, and the liquid suddenly diverged, turning into a three-inch-long red line, flying towards the one hundred and twenty-five sword slots that had already been prepared on the right side of the two of them.

In the blink of an eye, the liquid in the air had disappeared, just turning into one hundred and twenty-five red lines, merging into all the sword slots.

These sword grooves were carved with a material called Xuantie wood, each sword groove was three inches, and the liquefied Heavenly Star Meteorite had exactly one layer of one hundred and twenty-five sword grooves at the bottom.

Losing Yuehua Jinyan's refining, these liquids quickly solidified and turned into three-inch long sword blanks, as thin as paper.

"Okay, the most difficult materials to refine have been made, and then refining the Rotten Silver Essence and the Boundary Breaking Stone Crystal will be much faster!"

Before the girl's words fell, Xia Yin had already pointed her finger from afar, and the rotten silver essence on the ground flew into the air......

Xia Yin glanced at Yuehua Jinyan who was suspended on the side, and the red and white fire immediately turned into a pale red flame and went towards the rotten silver essence.

The power contained in this flame is actually very terrifying, it can be called melting gold and turning iron!

However, unlike ordinary flames, Yuehua Jinyan's power is extremely restrained, never released automatically, and looks like a blooming flower, beautiful and gentle.

However, Xia Yin and Zhang Rouran knew very well that it was this small flame, if the power completely exploded, even a big mountain would be melted!

And this hidden terrifying power, after enveloping the rotten silver essence, was quickly revealed.

Although the rotten silver essence is known for its sharpness, and its own material is also an extremely strong type, but under the wrapping of Yuehua Jinyan, it will be refined into liquid in less than a stick of incense!

This does not mean that rotten silver is easy to refine.

On the contrary, the rotten silver essence is also a high-level material that is relatively difficult to refine, if it is the Dan fire in the body of an ordinary Jindan monk, or the fire of the earth lungs, if you want to refine this piece of rotten silver essence, it will take at least ten days, and the real fire in the body of the Yuanying monk also needs three or four days, but the power of Yuehua Jinyan is too terrifying, so in just one stick of incense, this material will be refined into liquid!

If it was when Xia Yin was refining the rotten silver essence, Zhang Rouran would directly add the smelting rune, and the rotten silver essence would be refined in an instant, but the girl still had to keep the smelting rune in her body to prepare for the next most critical link, so she could only let Xia Yin drive Yuehua Jinyan to complete the sacrifice alone.

This also shows the extreme hardness of the Celestial Star Meteorite!

Under the smelting runes of Yuehua Jin Yan and Zhang Rouran, they persevered for a whole year!

And when the rotten silver essence turned into liquid, the girl Zhang Rouran concocted it in the same way, pinched the trick and recited the spell, and the runes were integrated into the liquid one after another......

These runes, except for the runes that remove impurities, are the same as last time, but the other runes are different, they are no longer to increase the hardness of the material, but specifically to improve the sharpness of the material!

After the runes were fused, Zhang Rouran pointed continuously, and the rotten silver essence in the air also turned into one hundred and twenty-five red lines, which slowly flew towards the sword groove, and finally covered the Celestial Star Meteorite Iron Sword Blank that had solidified and formed.

All the sword blanks that were originally gray were covered with a layer of shiny silver in the blink of an eye.

At this time, Xia Yin was a little bent, and a boundary-breaking stone crystal flew up and was wrapped in Yuehua Jinyan......

The refining of the Boundary Breaking Stone Crystal is much faster than the first two materials.

In the blink of an eye, the crystal clear boundary breaking stone crystal turned into a large drop of the same crystal clear liquid!

After Zhang Rouran's runes were fused one by one, the impurities in the boundary breaking stone crystal were quickly removed.

Xia Yin bent his fingers, and this large drop of Boundary Breaking Stone Crystal liquid flew towards a sword slot......

Unlike the rotten silver essence that covered the Celestial Star Meteorite, this large drop of crystal liquid was directly integrated into the two materials and disappeared without any change in the sword blank in the sword groove!

And Xia Yin did not stop, continued to concoct the same method, refining more than a hundred boundary-breaking stone crystals on the ground one by one, and under the purification and strengthening of Zhang Rouran's runes, a drop of boundary-breaking stone crystal liquid was integrated into one hundred and twenty-five sword blanks......

The smelting of the three main materials is finally complete!

Next, there is another extremely important step - to smelt the three materials and other auxiliary materials into one to become a real flying sword.

Zhang Rouran bent her fingers a little, and a sword blank flew up from the sword trough, suspended between the two of them.

Xia Yin guided Yuehua Jin Yan and wrapped the sword blank again.

And Zhang Rouran also pinched the trick and recited the mantra, and pointed out the ......

This time, there were not hundreds of runes flying out one after another, but only a few runes, which merged into the flying sword in the air.

But that's enough!

These three materials also contain a large amount of fire element power, and after Yuehua Jinyan's wrapping and several smelting runes are integrated, the entire sword blank quickly turns red......

Xia Yin's mouth began to chant incantations rapidly, and his hands shot towards this red sword blank like lightning!

And Zhang Rouran pointed from afar, and the red sword blank automatically flew forward to a formation that had already been built......
