Walking into the valley of the Strange Mine, every step will make an echo.

Although he didn't say anything along the way, Ilte still looked at the rusty sword hanging on Ressa's body from time to time.

Allen's acumen came into play again,

"You seem to care about this sword?"

Alan touched Resa's muscular neck.

"No, I'm just curious that you're used to using this sword."

Ilt went on to say,

"This sword was made from ore that I dug up here with my own hands. Suffice it to say that it would never be an exaggeration to call her the lightest sword on earth, mmmm. ”

"You can even forge a sword?"

Tia looked at Ilt in astonishment, wondering how much of a boy of our age had not yet been revealed.

"I'll tell you, healer is just one of my identities, and I'm the smartest person in Odaheim!"

Ilt raised his eyebrows and said proudly.

"Indeed, the sword is very light, and it seems to get lighter and lighter in the course of the battle. But why is it rusty? ”

Alan picked up the sword and looked at it carefully: Since it is made of ore, why can't I sense the energy of this ore? The doubts in Alan's heart seemed to be seen by Ilte,

"Alan, don't you see what ore this sword is made of? This is normal, even if you may read countless stones, but you can't know about this ore. Because, she is made of air. ”

"Air? Ilte, don't sell it, I also have research on ore, where is there any ore made of air. ”

Tia urged Ilt to explain.

"When we say air, we don't mean ores. It's the Sword Domain, Allen, what the Sword Domain is, you should know it very well. ”

"Of course."

"What is the Sword Domain?"

Thea pouted and looked at Eren suspiciously,

"Each sword has its own unique sword domain, and when a swordsman initiates a skill or uses a swordfight, the area drawn by the sword body is called the sword domain."

Alan patiently explained to Tia.

"Alan is right, but this is just a theory, experienced through practice, and the sword domain does not simply refer to this range, it actually contains a three-dimensional multi-dimensional space delineated by sword power, sword qi and sword length. In this space, if it is a normal sword, it may only be able to move in the third dimension. In layman's terms, it is to slash straight at the other party. But if it's a good sword, it's a different story, take this 'Erinius', for example, this sword is made by fusing the lightest gas ore with the hardest Hader gem today."

"Wait, I know both of these ores, and even if I change their appearance, I can still recognize them. But now the question is, I look at this rusty sword, and I still can't make out it, why is that? ”

Tia looks like a good student,

"That's because I joined the Stygian Limes."

"Ahh

Tia suddenly brightened,

"Ilte, you're a genius!"

"The Pluice Lime can mask the temperament of any ore and make the sword itself reverberate, so I can't feel the essence of the sword, and I can't exert her true power."

Alan sighed,

"And as far as I know, the ore of the Dark Lime is not so much an ore. It is a kind of powder that floats in the air in a powdery form all year round. It's usually only possible to find it in the deepest part of the mine, how did you manage to find it and bring it out of the mountains? ”

"I forged the sword, and I took the sword to find the Stygian Lime, and I searched for it in the strange mine for six months. Seek, collect. Once lost, look for it again and collect it again. In the end, I found that when I needed to find it, I went straight to the local source. Combined with my genius sword-casting method in this mine, I directly completed the casting of 'Erinius'. ”

"And what's different about her sword domain?"

Tia became a curious baby, asking one question after another

"The sword domain of 'Erinius' is completely different from ordinary swords due to the extraordinary material of the sword body. It has been explained just now, an ordinary sword, a three-dimensional attack range. The better sword is multi-dimensional. And this one, the space drawn by the sword body will be controlled by the unique floatiness of the Stygian Lime, coupled with the lightness of the gas mine, that is, it will be surrounded by the sword domain almost three hundred and sixty degrees without dead ends.

Not only that, but the entire sword will be very light when wielded, and it will become lighter and lighter due to the volatilization of the Stygian Lime during the continuous slashing, in order to prevent the sword from being broken by the reaction force due to the loss of mass. I also added the Harder Gem to it.

It's just that this sword shouldn't be able to be used by others. Ordinary magic swordsmen or swordsmen can't use a weapon that doesn't have the sense of a sword. ”
