Sunny concentrated on creating the alloy. There was little common sense to
what he was doing now, since the qualities of the materials transcended the
mundane. The foundation of the alloy was a piece of the mystical ice that had
once been the heart of the Transcendent Titan, Winter Beast. The metals were
no less storied, sourced from the treasury of the royal clan at great expense.

  

The flame had come from the soul of Changing Star… another Transcendent Titan.
Of course, Sunny was not simply melting the materials by exposing them to the
immolating heat of her fire — he had to use a crucible, which seemed to defeat
the purpose.

  

So, he had created a special crucible first, one that was both capable of
withstanding the destructive power of soul flame and able to channel it
instead of simply transferring heat. The first attempt at casting the crucible
was a Memory, but in the end, Sunny had to employ Cassie's help to create a
special runic enchantment.

  

That was because there was an inherent problem with using soul flame while
weaving…

  

Sunny sighed and explained as metals slowly melted in the incandescent
crucible:

  

"We are using your soul flame for forging because, as far as I can tell,
personal affinity between the Memory and its master plays a great role in
binding the two together. That was what I observed when dealing with a
soulbound relic left behind by the Demon of Destiny, at least… there was an
arduous condition that one had to meet in order to bind it, which I assumed to
be a test at first. But later, I started to suspect that it was as much of a
necessity as a challenge, meant to foster mutual affinity."

  

In hindsight, it made sense that Nether had been the one to create Soulbound
Relics. These relics were able to grow and change with their owners, after
all, almost like living beings. Considering how obsessed the prideful daemon
had been with creating life, it was unlikely to be a coincidence.

  

The metals had already turned into incandescent liquid, but the mystical ice
still remained, radiating an oppressive feeling of cold. Sunny continued:

  

"Therefore, a Memory forged in the fires of your soul would naturally have a
high affinity to you. Sadly, there lies the problem… your flame is simply too
tyrannical."

  

Nephis raised an eyebrow.

  

"How is that a problem?"

  

Sunny smiled.

  

Indeed. He had not expected to encounter this particular roadblock, either.

  

"Usually, I create the vessel first, and then enchant it. But this Memory is
quite special, so forging and enchanting have to happen at the same time —
that way, the weave will be integrated into the very essence of the sword.
Your flames can burn anything, though, material or immaterial. They can even
burn souls."

  

Nephis tilted her head a little.

  

"...And you create enchantments from strings of soul essence."

  

Sunny chuckled.

  

"Indeed. I need your flame to create the sword, but it will be destroying the
essence strings as I weave them together. It's a bit of a conundrum."

  

Nephis remained silent for a moment.

  

"I bet you have come up with the solution already, though."

  

Sunny looked at her curiously, then nodded.

  

"True… took me a while, but I did. I tried all kinds of methods trying to
isolate the essence strings and protect them from the flame, but actually, the
answer was ridiculously simple."

  

She raised an eyebrow.

  

"What is it? I'll say… it's a bit disheartening to hear that there's a simple
way to render my flames harmless."

  

Sunny laughed.

  

"Well, it's just the nature of the essence strings themselves, you see. Before
today, I've been using my own essence to create them, naturally. But for this
Memory, we will be using your essence instead. Since the flame and the strings
will be of the same source, one won't destroy the other. Using your own
essence to construct the spellweave will increase the affinity of the Memory
further, as well."

  

Sunny used one of the Quintessence Pearls installed near the furnace to fan
the flames. The heat grew almost unbearable, and beads of sweat glistened on
his porcelain skin like pearls.

  

The mystical ice was starting to give in to the soul flame.

  

"We would have had to get inventive to extract your essence if you were an
Awakened. But you are a Saint… your soul has already escaped the limitations
of your body, and your essence flows free, permeating the world. So, that step
should not be too troublesome as long as you cooperate."

  

Nephis studied him for a while and smiled.

  

"It's strange."

  

Sunny looked at her in confusion.

  

"What is?"

  

She simply smiled.

  

"Just how… nonchalant you are about this. Every step of the way seems to
demand inventing something that has never been done before, and yet you keep
coming up with these revolutionary and elaborate solutions, not even bothering
to acknowledge them as something important."

  

He stared at her for a few moments.

  

"Well, that's just science, isn't it? People who built the Obel Scale were
doing something that has nothing been done before, too. Or those who had
developed the earliest concepts of spelltech. Today, there is a woman in
Bastion who is trying to build a working electrical grid in the Dream Realm… I
bet she's going to succeed, too. It seems daunting, but finding solutions is
what we, humans, are best at. Especially when motivated by necessity."

  

Still… Sunny was secretly delighted by the compliment.

  

He watched the small piece of ice turn into a liquid. It was definitely not
water, and Sunny had no idea what the liquid actually was… however, he knew
that it always remained cold, never boiled, and never evaporated.

  

It was also not going to remain a liquid for long.

  

The incandescent metals mixed with the melted ice, and he swiftly poured the
searing silver mass into a small mold. A few moments later, it had already
solidified, turning into a bar of lustrous steel.

  

Well, it wasn't actual steel, of course. Rather, it was an alloy that had
never been created before, and therefore had no name.

  

Sunny was pretty certain of its deadly qualities, though.

  

Picking up the silvery bar, he weighed it in his hand, then studied it
carefully.

  

If not for his outstanding resilience to elemental damage, his hand would have
probably already turned to ice and shattered. The alloy was cold… dreadfully
cold.

  

Cold enough to make him shiver.

  

But more importantly, it possessed all the qualities that were needed to forge
a sublime sword.

  

The last experiment was successful.

  

Sunny smiled.

  

"This… will cut."

  

A blade forged from this would be sharp enough to cut the world.
