Let Go Of That Primordial Man

Mr. Niu is a little familiar with the copper of Shoushan.

It seemed that when he was in the current plane, he had heard of a certain material used in refining the legendary Xuanyuan Sword.

But for the Essence of Gold and Iron, the Iron Mother of Bei Gu, etc., I guess even after being connected to the Internet, I could not find any reliable answers using the thousand-degree search that claims to be omniscient.

However, a living person would never be choked to death by urine, so Mr. Niu still thought of a solution that was not a solution.

After picking through the portable space, he found that there were hundreds of tons of weapons and armor made of various alloy materials.

These weapons and armor were all spare parts that Mr. Niu kept in his personal space when he fought against the Witch Palace the year before last.

Nowadays, as the area of ​​Mr. Niu's portable space has gradually expanded to an astonishing size; Mr. Niu has always kept this batch of equipment in his portable space and is too lazy to clean it out.

At this time, Mr. Niu planned to smelt and purify these equipment, and then try his hand at making a flying sword...

First, Mr. Niu rummaged through all the equipment in his portable space one by one.

Even because he was worried about not having enough materials, Mr. Niu rummaged through his personal space for anything with iron in it; such as iron pots, kitchen knives, camel pot machines, etc.

The three stone chambers in this cave were completely piled up, leaving only a few feet of open space in front of him before he stopped.

Then, according to the method on the jade slip, Master Niu first tried to activate the elixir fire.

He activated the golden elixir in his body in the same way, and soon a purple flame about half a foot long appeared on the fingertips of Mr. Niu's left hand.

Seeing this purple elixir fire, Mr. Niu frowned.

This doesn't seem to be a smooth start, because according to the description on the jade slip, among the several types of elixir fire introduced in it, purple is the only one.

Moreover, there are no faint thunder patterns on any pill fire.

Just thinking about the strange purple thundercloud surrounding Jin Dan, Mr. Niu felt that it was not so difficult to understand.

Mr. Niu, who had forcibly convinced himself, officially started the first step of sword refining, the purification of materials; this guy grabbed a shield and placed it on the pill fire.

This purple elixir fire is extremely magical.

It was obviously a terrifying temperature, but it had no impact on Master Niu's hands that were very close to him. However, after the shield was put down, it changed in the blink of an eye.

The entire shield quickly turned into molten steel, and in the process of this change, a large amount of substances that Mr. Niu couldn't figure out were vaporized.

The shield turned into red molten steel, at most only a small half of the previous shield's volume.

Even so, it is only the first step in purifying the materials; the magic weapons and flying swords in this world are able to possess all kinds of powerful powers.

The formation engraved on it is one aspect.

Another important aspect is that the materials have been repeatedly purified to an unimaginable extent so that they can withstand high-intensity use and combat by users.

In the end, the molten steel formed by melting a shield was repeatedly refined by Master Niu until it was the size of half a small steel needle and could not be further purified.

Seeing this little bit of essence, Mr. Niu knew that this was what he wanted.

However, if he wanted to use such essence to finally refine a flying sword that he could master, he would need to repeat the steps just now many times.

After feeling the true energy in his body, he didn't spend much.

Mr. Niu first put away this little bit of essence and threw aside the fist-sized lump of impurities. Then he grabbed a thick-backed machete and started refining it again.

In this way, Mr. Niu calmed down and started refining the raw materials.

Whenever the true energy in the body is insufficient, Mr. Niu will stuff a pill into his mouth and practice some practice with the help of the rich spiritual energy of heaven and earth around him.

After the real energy in the body was abundant again, a new purification of materials began.

Gradually, the weapons and armor around Mr. Niu had been consumed. At this time, feeling that the refined essence was still far from enough, the guy started to use kitchen knives and large iron pots again. Start...

****

It's a pity that Mr. Niu is hiding in the cave. What this guy doesn't know is:

Otherwise, even the masters of weapon refining in this world would scream in surprise when they saw his generosity; he actually used so much high-quality black iron to make a flying sword.

Such a luxurious approach can simply be described as crazy.

Yes, that's right! Even in this world favored by the Emperor of Heaven and the Gods, the metal processing methods it possesses have only just reached the stage of iron tools.

In the modern plane, alloy steel is cheaper than salted fish. Only cultivators here can refine it into something of similar quality.

They called this thing Black Iron, and it was very expensive.

As for the last bit of essence processed by Master Niu, it is the legendary black iron essence; it is extremely rare and priceless.

The main reason is, first of all, problems with raw materials.

In this world, the most common method used by ordinary weapon refiners is to use ores to directly refine the required materials.

With the primitive mining methods of this era, ordinary miners would need to work for a long time to refine a hundred pounds of black iron, which is equivalent to several hundred yuan of alloy steel.

Even the most high-end weapon refiners possess the most luxurious means in this era.

To top it off, that is to say, they use the best refined iron to purify the materials they need; using precious materials such as black iron is a method that even the masters of weapon refinement dare not imagine.

Secondly, there is the issue of refining capabilities. .

The elixir fire possessed by the refining master is the most important key issue that limits each refining master; if you want to refine it to the point of black iron essence, you need extremely advanced elixir fire.

Every weapon refiner who can purify the essence of black iron is respected as a weapon refiner master.

It seems that there is no master refiner on the entire Giant Coconut Island who can purify the essence of black iron. Counting the dozen or so large islands in the surrounding area, there are only two such figures.

Only one of them is from the human race, and the other is from the demon race.

Therefore, if a flying sword can use a few pieces of dark iron essence the size of sewing needles on the most important blade, it can be called a top-grade flying sword.

The head of the Zixiao Sect, Yun Ao, promised to distribute it to Mr. Niu. The flying swords of the rising stars in this sect can only be of this quality...

Half a month later, when Mr. Niu had finished refining and purifying the last engineer shovel in his hand.

There are no longer any steel products in the entire cave; instead, there are waste slag all over the floor, and if measured by ordinary alloy steel, it is a lump of black iron essence weighing eight or nine kilograms.

But in reality, this lump of black iron essence may weigh no less than ten thousand kilograms...
