The golden dragon pattern giant sword was nothing else, it was the new sword tire that Li Aotian had spent several days refining for the Longyuan Sword with ten kinds of saint-grade essence gold as the main material.

Refining flying swords with ten kinds of saint-grade pure gold as the main material, although this cannot be said to be unprecedented in the Sea Blue Star, it is definitely an extremely rare feat, if this is spread, it will definitely cause quite a stir in the cultivation world.

Saint-grade Adamantite, this is a collective term for the Adamantite materials that can be used to refine the Eighth-Order Hallow.

On a third-level cultivation star like Sea Blue Star, which has poor cultivation resources, it is extremely difficult for ordinary people to find a kind of saint-grade essence gold, let alone obtain ten kinds of saint-level essence gold at once and refine it into a flying sword.

Since the rebirth of the soul of the Sea Blue Star to the present, Li Aotian has not seen a magic weapon refined with saint-grade fine gold, but the most extravagant of them is just the dragon lock of the Dragon Star War.

Li Aotian still remembers the dragon lock, according to the Dragon Star War that day, it was a magic weapon refined with six kinds of saint-level essence gold.

In the battle of the royal family in Feiyun City that day, Li Aotian suffered a lot of losses in the dragon lock, and in the end, if it wasn't for the undefeated exit to save him, I don't know what the result would be.

The reason why Li Aotian suffered a loss in the Dragon Binding Lock was not because of how high the level of the Dragon Binding Lock was and how powerful it was, but because the Dragon Binding Lock was refined from six saint-level essence gold.

The hardness of the saint-grade essence gold was far beyond that of ordinary refining materials, even if the dragon binding lock at that time was only at the sixth order, with Li Aotian's powerful body, it was not at all able to break free.

Even now, Li Aotian's cultivation has reached the realm of Daojun, and it is very difficult to break through the magic weapon refined by the six kinds of saint-level essence gold by brute force, this is not to say that Li Aotian's body is not strong enough after the body is sanctified, but the magic weapon carcass refined by the fusion of six kinds of saint-level essence gold is too hard, and only the undefeated sharp teeth against the sky can just be restrained.

"If I had used a lot of saint-grade essence gold to refine the Longyuan Sword from the beginning, then the Longyuan Sword would not have been damaged in the battle of Wood Spirit City that day, and as a result, I would have gone to the Ghost Gate to walk for a while, and I almost lost my life. ”

"As the saying goes, eating a crab grows wisdom, I will never let this happen again in the future!"

Holding the dragon pattern sword fetus in his hand tightly, Li Aotian's eyes showed a trace of fierce brilliance.

Without wasting time, Li Aotian took the Longyuan Sword and walked directly to a huge fire-gathering array in the center of the secret room.

This fire-gathering array platform is more than ten zhang wide, and it is not only covered with a large number of simple and mysterious runes, but also inlaid with thousands of high-grade yuan crystals.

In the center of the fire gathering array, there is a circular fire vent that is a few feet square, even if the array platform has not really been activated, the fire vent still exudes a blazing heat, like a small crater.

Raising his hand, he shot out a stream of True Yuan and landed on the Gathering Fire Formation Platform, and Li Aotian did not hesitate to stimulate the Formation Platform.

As the array platform was activated, all the ancient runes on it lit up with a dazzling red aura.

I only heard a muffled sound of "hum", and a blazing dark red flame suddenly erupted from the fire outlet in the center of the fire gathering array.

This dark red flame looked like an extremely earth fire, but the terrifying heat it emitted was more than a hundred times stronger than ordinary earth fire.

This means that Li Aotian's physical body is strong enough, if he were an ordinary person, he would definitely be baked into charcoal if he approached the Gathering Fire Array at such a close distance.

"Thanks to Long Yan preparing this high-level fire gathering array platform for me, which can refine saint-grade essence gold, otherwise, it would really not be easy to refine the Dragon Yuan Sword Fetus in a short period of time. ”

Not affected by the high temperature emitted by the Gathering Fire Array, Li Aotian muttered softly, and then sent the golden sword tire in his hand into the dark red flames spewed out of the fire outlet with True Yuan.

Under the intense calcination of the dark red flames, the golden sword fetus was quickly burned red, and even some rune formations originally engraved on its surface quickly turned invisible.

Not in a hurry to refine the golden sword fetus, Li Aotian took out the fifteen kinds of saint-grade pure gold from the storage ring, and then carefully selected it.

After some strict selection, in the end, Li Aotian only selected eight kinds of pure gold that were most suitable for the Long Yuan Sword, and the remaining seven kinds of pure gold were abandoned by him.

Giving up seven kinds of saint-grade essence gold at once when refining a magic weapon would definitely feel a pity in the eyes of others, but Li Aotian didn't care about it, because he knew very well that not all refining materials were suitable for smelting into a magic weapon.

Refining is the same as alchemy, the higher the quality of the raw materials, the better the quality of the finished products, but not all good quality raw materials are suitable for smelting together.

As far as alchemy is concerned, the medicinal properties of different attributes of elixirs are different, if they are properly matched, they can naturally refine good elixirs, but once they are not properly matched, the elixirs with conflicting medicinal properties are matched together, and the light ones cannot become pills, and the elixirs become poisons, and the harm is endless.

In the same way as alchemy, the properties of some refining materials are also conflicting, such as cold iron and red gold.

The former of cold iron and red gold is of the Yin and cold attributes, which is suitable for refining Yin and cold magic weapons and magic weapons, while the latter is fire attribute pure gold, which is suitable for refining fire attribute magic weapons and magic weapons, if the two are forcibly smelted together, then the refining of magic weapons will definitely fail.

The seven kinds of adamantine that were given up by Li Aotian all belonged to the adamantine that conflicted with the material of the golden sword fetus.

Although these seven kinds of pure gold are all rare saint-level materials, smelting into the sword body has no benefit, but will reduce the quality of the sword fetus, and it is precisely because of this that Li Aotian will choose to give up.

After determining the materials, Li Aotian raised his hand and waved his sleeve robe, and smashed all eight kinds of pure gold of different colors into the dark red flame where the golden sword tire was, and calcined it violently with a fierce fire......

Staying in the refining room is three days and three nights.

When Li Aotian walked out of the refining room, he had an extra domineering dragon-patterned broadsword in his hand.

Compared to the golden giant sword three days ago, the Dragon Yuan Sword Fetus, which was infused with eight kinds of saint-grade essence gold, looked even thicker, it was about five feet long, and the thickest part in the middle of the sword body was nearly three inches long.

In addition to the length and thickness of the flying sword, the width of the Longyuan sword tire is also quite amazing, nearly a foot long, and the entire flying sword stands upright on the ground, like a golden door panel, looking domineering and exposed.

As soon as he walked out of the refining room with the Longyuan sword tire, Li Aotian immediately drove the light and left Tianlong Peak.

A moment later, Li Aotian came to the top of a stone mountain not far from Tianlong Peak.

Compared with the towering Tianlong Peak, the stone mountain where Li Aotian is located looks very short, but if there is no Tianlong Peak as a comparison, this stone mountain is actually not short, because it is nearly seven or eight hundred zhang high from the ground to the top of the mountain.

"Although you haven't been integrated into the Instrument Spirit yet, no matter how you say it, you have also used eighteen kinds of Saint-grade Essence Gold and have been tempered thousands of times, so don't disappoint me. ”

Muttering softly to the Longyuan sword fetus in his hand, Li Aotian raised his hand and slammed it on the stony ground under his feet.

I only heard a loud "boom".

As Li Aotian landed with a sword, the stone mountain under him instantly shattered from the top of the mountain to the foot of the mountain, turning into countless gravel and scattering in all directions, and the picture looked extremely spectacular.

You must know that Li Aotian's sword did not use any true yuan, even if it was his physical strength, he deliberately only used a small part, it can be said that the shattering of the entire stone mountain was almost entirely caused by the power of the Longyuan sword fetus itself.

"The Black Scale Heavy Iron and the Extremely Heavy Meteorite Gold are really good, although the weight of the Longyuan Sword has been increased to 108,000 catties, but it has also greatly increased the destructive power of this sword, this is still the result of me deliberately not using too much physical strength, once I use all my physical strength, I am afraid that this mountain will have already turned to ashes. ”

Looking at the large pile of rubble on the ground, Li Aotian showed a shallow smile on his face.

Without stopping the sword test, Li Aotian shook his right hand and shot the Longyuan Sword Fetus in his hand directly towards another stone mountain not far away.

This is a stone mountain with a pitch-black body like ink, and in terms of size, it is nearly twice as tall as the stone mountain that has been smashed by Li Aotian's sword.

There was another loud "boom".

Under the impact of the Longyuan Sword Fetus, the black stone mountain, which did not look small, turned into flying ashes in an instant, and its fate was even more miserable than the first stone mountain.

With the destruction of the second stone mountain, Li Aotian used the True Yuan Imperial Sword to urge the Great Firmament to break the sword style, and slashed out a dazzling golden sword gang towards the mountains in all directions.

The golden sword was hundreds of zhang long, and under its sweep, one nearby mountain peak after another was cut off like tofu, and the picture looked as if the world was destroyed.

"Aotian, don't you want to destroy my Heavenly Dragon Realm!"

The space fluctuated in a flash, and a white-robed dragon suddenly appeared not far in front of Li Aotian, looking at the picture full of sores in front of him, Long Yan's face was unusually ugly......
