Jiang Mu stood in front of the huge Qiankun furnace, thoughtful.

He didn't plan to replace the Qiankun Furnace and the Mechanism Pioneer Beast for the time being, because this set would require at least five thousand spirit stones, which would definitely not be hidden from Senior Brother Yao Cheng.

But he could have tried something else.

The magic trick in the palm changed, one by one, and fell into the Qiankun furnace, and in a moment, the Qiankun furnace opened a huge crack, and suddenly a heat wave hit, and when you look closely, it is all ore that has been refined into molten iron.

At this time, Jiang Mu took a remote shot of the void with his right hand, urging the Dao Dao method, out of thin air, as if there was a big hand, taking out a large amount of molten iron from this Qiankun furnace, almost the size of a three-story building.

But this molten iron is controlled by Jiang Mu with mana, but it is like the dough in the hands of a giant, kneading it as much as he wants, and at the same time, Jiang Mu is even more distracted and multi-purpose, using all kinds of different tricks to act on this molten iron dough, as if there is a huge forging hammer beating invisibly.

A large number of impurities continue to fall from it, and the entire molten iron dough also shrinks rapidly.

The whole process lasted for about half an hour, and the molten iron dough had shrunk to the size of only one wheel, and at this point, a little solemn look appeared in Jiang Mu's eyes, and with a spell in one hand, the void was drawn, and a large amount of heaven and earth aura was attracted like a whirlwind, and in an instant, it was compressed into spiritual liquid and poured on the molten iron dough.

In the blink of an eye, a cyan iron ingot was formed, and a natural texture was naturally formed on it, like a flying phoenix hovering for nine days, exquisite and breathtaking.

This is definitely not just the best black iron, but the best black iron.

Jiang Mu's face turned a little pale, and there was only a trace of mana left in his body, this method was really not an ordinary mana consumption, he almost fell short.

Thankfully, it worked.

Of course, this is not the method of quenching Xuantie handed down by the Fuyun Sect, although the Fuyun Sect is also a well-known Xuantie forging sect, but in fact, it is not ranked at all in the immortal cultivation world.

Not to mention anything else, there are five kinds of Xuantie, including lower grade, middle grade, upper grade, best grade, and divine grade, but the Floating Cloud Sect can only smelt the upper grade.

This method is from the Divine Sword Gate.

The method of converting mana into sword yuan power actually includes the core technique of the Divine Sword Sect [Imperial Divine Machine Palm Sword Technique], which has an article called [Nine Heavens Quenching Method under the Spirit Attracting Machine], which is a method that can be tempered to create a divine product Xuaniron, and it is also a method for casting flying swords.

I have to say that the Divine Sword Sect is unique in this regard, no wonder it can create a way to convert mana into sword power.

Now it's cheaper than Jiang Mu.

At this time, after Jiang Mu meditated and breathed for a while, he held the cyan Xuantie in his palm, injected a little mana, and flicked it lightly with his fingers, and suddenly the sound of the dragon chanting Qingyue jumped out, and even the cyan edge appeared like a gangfeng, and even left blood-red traces on his palm.

Gold and iron, the murder weapon, even if it is not forged, has its own fierce aura, from the perspective of various qualities, it is the best dark iron.

In the four square cities of Qinge County, there are only three or five pieces of top-grade dark iron every year, and each piece can be sold for a high price of three thousand spirit stones.

But the point is, you may not be able to buy enough spirit stones.

Jiang Mu is deeply aware of this, his second senior brother Xu Yi wanted a piece of superb Xuantie to build the Natal Flying Sword, and Jiang Mu also wanted to buy it with a lot of money.

However, the buyers of the best Xuantie are basically immortal cultivators of the Yuanying Realm, even if the Floating Cloud Sect is one of the five tyrants of Qin Ge County, as long as there is no Yuanying Realm in the sect for a day, it will not be able to rob others for a day.

It's not a matter of how many spirit stones there are.

And now, he was able to quench a piece of top-grade Xuaniron, if this news spread, I am afraid that it would immediately shake the five counties of Shannan, but then, the foundation of the Floating Cloud Sect for more than 3,000 years is afraid that it will not be able to be kept, because the flying phoenix texture on this piece of top-grade Xuaniron is the only one in the world, and there is no other semicolon.

"Excalibur Gate ......"

Jiang Mu smiled bitterly, now he not only has this [Nine Heavens Refining Method under the Spirit Attracting Machine] in his hands, but also the core technique of the Divine Sword Sect [Imperial Divine Machine Palm Sword Technique], and people who want to come to the Divine Sword Gate will not listen to his explanation.

It would be fine if the other party was just a small sect, but in fact, the Divine Sword Sect was one of the top sects under the five super sects in the Immortal Cultivation Realm today.

The super sect refers to the sect that has been inherited for more than 100,000 years, and there are immortal cultivators in the realm who are in charge of the sect, and the influence is huge.

The top-level sect refers to the sect that has more than three old monsters in the God Transformation Realm in the sect, and it doesn't matter the inheritance time, it doesn't matter the prestige status.

Since the establishment of the Divine Sword Sect, it has only been more than 9,000 years, it is said that the founder of the mountain is an outcast of a super sect, very mysterious, very low-key for thousands of years, until nearly a thousand years to raise the profile, now there are five gods and old monsters in the door, and the master of the Divine Sword Sect who became an old beggar in his last life is one of them.

Jiang Mu knew that this matter was sensitive, so he summoned Liu Tiezhu and asked him and Cheng Banjin to be in charge of the sect's affairs in the near future, while he wanted to retreat Yunyun.

Then, he stepped onto the teleportation array in the smelting hall, pinched the magic technique, and in an instant, he was already in the dark iron veins hundreds of miles underground.

For the time being, there is no safer and more secluded place.

"Boom!"

In a space like a giant city, Jiang Mu's divine thoughts swept by, and twenty Trap Mountain Beasts were mining ore in one mine after another day and night, and everything was normal.

In this place, Jiang Mu would come every few years to replace the spirit stones for the Organ Beast, so although the mine cave was as complicated as a labyrinth, for him, it was really like a leisurely stroll.

Casually found a depleted mine cave, Jiang Mu sat cross-legged in it, first restored the mana, and then silently recited the [Imperial God Machine Palm Sword Technique].

The first step in converting mana into sword power is to practice this exercise.

Because the head of the Divine Sword Sect in the previous life had spoken first, the method they created was actually just a rough blank, because there was not enough aura to try, and it needed to be constantly revised and improved.

Therefore, Jiang Mu has to know himself and his opponent.
