Nalan Yande changed his previous rickety old state, his muscles rose suddenly, his left hand controlled the heaven and earth fire in the giant ding, and his right hand held a fierce hammer to attract the power of heaven and earth thunder.

The strange fire of heaven and earth in the giant tripod kept rolling, and Yuan Chen stood aside, finding that the temperature of this strange fire was much hotter than the lava in the center of the earth in the sword smelting pool.

Wan Yanding and Silk Thunder Hammer are rare treasures in the Thirty-Three Heavens, inherited from two foreign emperor realm powerhouses in ancient times.

Wan Yan Ding is the treasure of the Fire Spirit Clan, which is said to be able to swallow thousands of flames in heaven and earth and refine them, and the Silk Thunder Hammer is made of the thigh bones and leather bands of the ancient Beast Emperor, "Kui Niu", and the power of a hammer is enough to shatter a small world.

"The old man even took out Wan Yanding and the Silk Thunder Hammer, it seems that this sword embryo does have the assets of an artifact, and it deserves his so much attention. "Concubine Nalan Xuan is watching from afar, it is very rare for the ancestor to refine the battle weapon, this kind of opportunity is very popular even if she has become a "earth master".

Since the ancestor thinks that the sword embryo taken out by Yuan Chen this time has the potential to be used as the base material of the artifact, it means that the ancestor is going to do his best to cast an artifact sword, and this kind of opportunity to watch may only be encountered once in her life for Concubine Nalan Xuan.

If Concubine Nalan Xuan can comprehend anything from this refining process, I am afraid that she will be able to go further in the way of refining weapons in the future.

"Wow-"

The spiritual power of heaven and earth hidden in the depths of the underground palace poured in instantly, and a series of ten large-scale spirit gathering formations opened, and the majestic power poured into the Ten Thousand Flame Ding, and the raging fire rushed straight to the zenith.

The crimson fireworks kept pulsing, and their colors gradually changed, turning into a blue-blue edge.

"Cyan Flame?!" Yuan Chen's heart shook, it was worthy of the Heaven and Earth Alien Fire that had continued to burn from ancient times in Wan Yan Ding to the present, and the Great Dao rules contained in the flame alone had surpassed the vast majority of the Flame Dao.

Among all the different fires of heaven and earth that Yuan Chen knew, only the pure yang true fire and the qi flame fire could be compared.

"This is the natal flame of an Emperor Realm powerhouse of the Ancient Fire Spirit Clan, named 'Bihua Emperor Yan', which has been sealed in the Wanyan Ding. Seeing Yuan Chen's doubts, Nalan Yande explained, "This sword embryo of yours has been immersed in the lava in the center of the earth, and ordinary fire can't smelt it at all, only 'Bihua Emperor Yan' can smelt the sword embryo and carry out the next step of forging." ”

Yuan Chen's head bowed, he carefully looked at Nalan Yande's refining methods, and his eyes were fixed on not even a magic seal.

"Take a piece of the crystallized phalanx bone of your right hand!" Nalan Yande said.

Yuan Chen did not hesitate to break off a piece of phalanx crystal nucleus on his middle finger, his right hand was in a state of skeletal bones, without any pain nerves, and it was not uncomfortable.

Yuan Chen's purpose this time is to forge the natal spirit sword, not an ordinary spirit sword, and this side requires the refiner to add the breath of the sword wearer as an introduction when casting the sword.

Ordinary sword cultivators will sprinkle their own essence blood when forging the sword, so that the spirit sword will recognize the master in advance.

However, the low temperature of human blood will inevitably cause the temperature of the refining weapon to drop sharply, resulting in a decrease in the quality of the final smelted spirit sword.

Yuan Chen used the finger bones this time, so he had no worries at all.

First, the human skeleton is the same as essence and blood, and it is enjoyed as soon as it is born, and it carries its own breath the strongest; secondly, Yuanchen's right finger bone has been completely crystallized, which is not much different from the quality of the Earth Center Yan Crystal he collected, and can be added to the refining materials as an auxiliary material, greatly increasing the quality of the spirit sword.

After collecting the phalanges, Nalan Yande

He threw out several rare refining materials and threw them into Wan Yanding, each of these materials is a unique treasure in the world, and only with the accumulation of hundreds of thousands of Nalan Yande can there be such a generous hand.

"Don't worry, I'll ask your master for the loss of materials this time, I'm not a good person. Nalan Yande said with a smile, the materials of the refining weapon this time were indeed a bit luxurious, to be honest, even with his savings, it was a little painful.

Each of these materials was enough to be used as the main ingredient of a Wanwen warweapon, but now it was thrown into the giant ding by Nalan Yande as if he didn't want money.

"It's still a big ingredient. Nalan Yande muttered in his mouth, he had carefully analyzed the attributes of the sword embryo, it was the first time in his life that he had seen the sword embryo with such pure sword intent, and it seemed that adding any kind of material as the main material to cast the sword would destroy the original attributes of the sword embryo.

Just as Nalan Yande was thinking, Wenren Mingyu spoke: "Brother Yande, I don't know if this thing can become the main material of this sword!"

As soon as the words fell, a crystal ore exuding a powerful sword aura was thrown out by Wenren Mingyu and flew in front of Yuan Chen and Nalan Yande.

Nalan Yande guessed the origin of this crystal ore before he even started, he looked at Wenren Mingyu and admired that this guy had really made a bloody contribution for his disciple this time.

"This is ......" Yuan Chen's knowledge is not low, just a point slower than Nalan Yande, that is, to see the identity of this crystal ore-

Pure Source Sword Crystal!

As long as the ore in the world is mined from the veins, there will be magazines mixed in, and the first step for warriors to use these ores is to eliminate magazines to prevent them from being affected by impurities.

Only in some places where the aura of pure heaven and earth gathers can it be possible to give birth to mineral crystals without the slightest other substance, and this kind of mineral crystals are called "pure source spirit crystals" by the world.

The "Pure Source Spirit Crystal" is extremely rare, because there are no impurities, it is extremely convenient to cultivate and use, and its value is far better than that of ordinary top-grade spirit crystals, which are often priceless and rarely sold in the Thirty-Three Heavens.

In the birth of the world's ores, the sword attribute veins belong to one of the rarest types, which need to be surrounded by a strong sword qi all year round, and it is possible to be born with continuous cultivation.

Looking at the entire Thirty-Three Heavens, only the sword mound of the Ten Thousand Swords Villa had such an artificial environment that it was possible to give birth to a sword-attribute vein.

"Sword Crystal" is also a fine product in the sword attribute ore, and it is rare for general sword cultivation to get it.

On top of the "Sword Crystal" is the "Pure Source Spirit Crystal", you can imagine how precious it is that Ming Yu took out such a main ingredient at this time.

The "Pure Source Sword Crystal" does not have any impurities, and it belongs to a mineral crystal that only contains pure sword intent inside.

The "dust-free" sword embryo is also the product of the mutation of pure sword intent, and the combination of the two simply complements each other.

Forging the materials taken out by others, Nalan Yande would not be in pain, he took the "Pure Source Sword Crystal" and threw it into Wan Yanding.

"Boom!"

The main ingredient was added, and Nalan Yande began to really enter the state of sword casting.

A massive amount of spiritual power was poured into Wan Yanding, and the Burning Sky Flame rolled up a sea of fire, smelting these mineral crystal materials into metal spiritual liquid one after another.

"Bihua Emperor Flame" surrounds these spiritual fluids, using the extreme temperature of the flame to gradually remove the impurities inside.

The "dustless" sword embryo is a rare and pure thing in the world, and if Nalan Yande wants to forge a sword from it, he must also use a pure thing.

"Get up!" Nalan Yande shouted angrily,

A lot of spiritual liquid flew out of Wan Yanding with a sword embryo wrapped in it.

Nalan Yande's hands instantly sealed, and a large number of sword dao sigils were smashed into the surface of the sword embryo.

In just one breath, Nalan Yande had already sealed tens of millions, each of which was a supreme refining seal.

The dragon-like muscles bulged, and Nalan Yande held the Silk Thunder Hammer in one hand, summoning the Nine Heavens of Thunder.

Above the underground palace is the main hall of the Fire Refining Union, and the power of thunder coiled above the main hall has not dispersed for a long time.

Electric dragons continued to fall, roaring thunder and lightning whipping on the bricks and tiles of the main hall.

"This thunderous momentum, could it be that the Ancestor is refining weapons?!" a refiner of the Nalan family wondered, he had never seen such a terrifying refining movement, almost exhausting most of the heaven and earth aura in the realm of the Fire Refining Union.

"It's Elder Taishang! Only Elder Taishang can have such power when he refines weapons!"

"Elder Taishang has not been out of the level for more than 100,000 years, and he is dedicated to cultivating the way of the weapon, is this attack to break through his limit?"

"More than 100,000 years ago, Elder Taishang's refining attainment was the pinnacle of the Earth Master, and one step further was the realm of the Heavenly Master of Refining Weapons!"

"The Heavenly Master can refine the artifact, and now that this heaven and earth vision, is the Supreme Elder really ready to forge the artifact?!"

"A few hours ago, I saw the Thousand Jade Sword Monarch of the Ten Thousand Swords Villa and the famous Yuan Chen come to visit the Elder, could this matter have something to do with them?"

......

......

Nalan Yande's refining this time was huge, attracting the attention of everyone in the Fire Refining Union.

Watching a refining earth master forge magic weapons is a rare opportunity, let alone a breakthrough made by a level of Supreme Elder in order to advance to the realm of a Heavenly Master.

This kind of opportunity to watch from the sidelines, even if they look at the momentum of heaven and earth from afar, is a great opportunity for them refiners.

"Bang!"

"Bang!"

......

The thunderbolt hammer contains an earth-shattering roar, and the power of a hammer is comparable to the weight of mountains and rivers.

"It is worthy of being an artifact that once hammered a small world. Yuan Chen sighed in his heart.

Whether it is Wan Yanding or the Silk Thunder Hammer, they are all rare artifacts in the Thirty-Three Heavens.

Only artifacts can forge artifacts!

The Nalan family has a deep heritage, and it is normal to have one or two artifacts.

Nalan Yande continued to enter the state, and a Kui Niu Phantom gradually condensed behind him, and the power of thunder was released from the silk thunder hammer, refining the sword embryo again.

Yuan Chen stood aside, he looked at the posture of Nalan Yande's refining weapon, and kept every magic seal and seal firmly in his heart.

"The Nalan family's method of refining weapons is not much different from the Yuan family's sword-forging method at the root. Yuan Chen thought in his heart, refining weapons have the same path, although the two are not fundamentally different, but the sword forging method inherited by the Yuan family is much more subtle than that of Nalan Yande.

Yuan Chen's father and mother are from different sword master families, and the way of sword forging is also different.

It is hard to imagine that one day he will completely master the sword-forging method of the two major families, and what kind of realm his refining method should reach.

Looking at Nalan Yande's sword-forging method, Yuan Chen continued to compare the sword-forging method inherited by his family, and the spiritual power in the divine sea was running at full speed, wanting to absorb Nalan Yande's sword-forging experience as much as possible.
