Before the casting of the corpse core, Emiya had already studied the casting characteristics of the corpse core through the system.

The comparison shows that the three sword casting spectrums, in terms of the casting process, all show that the corpse core cannot be smelted with other materials.

Instead, the new sword needs to be pleated and hammered, and after the temperature has been lowered, it is injected into the sword by "absorption".

This means that the melting point of the nucleus will be much lower than that of several other materials.

After a small amount of heating tests on the nucleus of the corpse in the Emiya, it was roughly determined that its melting point was around 150 to 200 degrees Celsius. (Emiya himself made a rudimentary but relatively sophisticated set of testing instruments for his own research through three years of free casting)

One thing that he cares about more is the biological nature of this [corpse core].

This thing beats on its own, like a collection of muscle cells, but it is not metabolized.

When it is heated to 100 degrees Celsius, it makes a strange noise, and it slowly turns milky white, and a strange smell with a fishy smell fills the air.

Yes, the strange aroma successfully aroused Emiya's appetite, just like cooking pork ribs.

Damn ......【Boiled pork ribs】

When this strange thought jumped into Emiya's brain, the whole person was not good.

But he still licked his lips involuntarily.

Damn, I'm such a pervert!

"You said before that the refining of the corpse core is a forbidden technique, so how is it refined?"

The system was silent for a moment, and replied to him, "I haven't included the specific method, but it is said that by soaking many corpses in a special solution at the same time, through slow erosion over many years, the corpses will gradually form crystals, and then by constantly adding new corpses to increase the final crystallization amount, so, such a large corpse core as you get, at least a thousand human bodies can achieve the effect." ”

When Emiya heard this, he didn't know why, and his stomach twitched, and just thinking about that image was uncomfortable enough.

It seems that Hu Hua's father is not a good thing.

No matter what the source of the corpse is, it is still immoral to do this kind of refining, and it is no wonder that in a world where murder is commonplace, these people in power have to ban this method.

However, when it comes to corpse nuclei, Emiya is still more interested in that special solution.

I don't know what chemical composition is able to achieve this effect.

Thinking of this, Emiya pursed his lips, if only he could go to his house one day.

It's just that Wei Gong can probably guess a few points in his heart, that thing is so magical, most of it is related to mental power (spirituality).

Many things in this world can no longer be explained by simple physics or chemistry, otherwise those things like Edgeworth's flight would not exist at all.

Wei Gong had suspected that these fairy swords were actually equipped with anti-gravity devices.

Later, it turned out that these things were completely different from what he thought, and there were many swords that were indeed no different from ordinary steel-carbon mixtures shaped according to a certain shape, the only difference was that when Emiya was cast, he had to rely on his own talent to give it spirituality.

Well, again, it's a very idealistic casting process.

During the casting process many times, he couldn't help but think of the legend of the cadre Mo Ye, who needed human blood to sacrifice the sword in order for the divine sword to be born.

The jade steel underneath (the top layer of the original iron, suitable for casting into a sword) was almost hammered, and it had gradually taken on a preliminary shape.

Emiya retracted his mind and prepared to let it absorb the corpse nucleus as the system said.

The corpse core is just such a piece, and Wei Gong doesn't want to ruin a good sword because of his curiosity, so he still absorbs the entire corpse core according to the weight that the system says.

The word "absorption" sounds a little strange, but it is.

Once again, the phrase flashed through Emiya's brain - the sword is alive.

"Sword Forger - Shadow Hand, open! Spiritual power infusion! The system emitted a series of mechanically cold sounds.

A green light gradually grew above Wei Gong's hands, and that light spread out, like flowing water, enveloping both of his hands in it.

He picked up the nucleus with one hand and the jade steel with the other, handing them together.

I saw that the corpse core slowly dissolved, and a burst of black mist was steamed, and before it escaped, it was immediately captured and wrapped by the green light in Wei Gong's hand, and then slowly absorbed by Yugang.

For every point absorbed, the nucleus decreases a little.

Wei Gong's brows furrowed, and fine beads of sweat oozed from his face.

After about an hour, the nucleus was finally absorbed.

"Hehe, it's time to witness the miracle!"

Emiya smiled evilly, holding the hammer in both hands, and struck quickly.

"Sword Forge - Shaping Super, on! Spiritual power infusion! ”

The sledgehammer of the palace flew over, holding a heavy hammer in each hand, and striking on the original steel underneath, with such a fast speed that it brought up an afterimage.

In a short time, it was in the shape he wanted.

After the tempering was heated, Emiya put the fiery red sword into the sink and quickly cooled it. This process is called quenching, and the quality of a sword is also determined by this, and one-third of the sword will die in this step.

However, after years of training, Emiya is already very handy.

I saw a wave of heat rising from the sink, and the sword body quickly turned cold and bright.

It was at this moment that a "ding" sound sounded in Wei Gong's brain.

"A new sword spectrum has been obtained, not yet named, codenamed X067

Grade: Iron Source Mortal

Category: Dark

Base Attack Damage: 23

Bonus Damage: 43

Defense: 12

Flight speed: 98

Flight Cost: 1.2

Durability: 100

Additional Skill: Recruit Zombies 3/3

Ranged Ability: None"

……

Seeing this, Wei Gong felt cool in his heart, and sure enough, it was still an iron source mortal product cast with low-grade materials, and the dismal attack power made people unbearable to look at directly, even after grinding and polishing it for a while, it was estimated that it would not rise too much.

It seems that he has cast a good material to waste.

He suddenly regretted it in his heart, it was really impulsive, the immortal material of the corpse core, if it was sold for money, it was estimated to be worth a lot.

But, "Ah, how can this be?!" ”

He's a little crazy.

Keep scrolling down to add skills.

The corners of Wei Gong's mouth twitched, "What the hell is this?" ”

Before the words fell, another "ding" sounded in my head.

"The system rewards an additional additional skill: Soul Search: 3/3."

Well, here comes another one that I don't understand.

"Congratulations on earning 15 XP,

Current Swordsmith Level: LV31

Next Level Experience: 27/6542"

Emiya waited for a while, but the system did not make any more sounds.

"Is it over? What the hell is recruiting zombies? And the soul search that follows, and what does the number that follows mean? ”

"[Recruit Zombies] is literally meaningful, you can turn dead corpses into zombies to drive yourself, each time you recruit a zombie, the number of consumption will be reduced once, after 3 times, this skill can no longer be used."

"And soul search, that is, you can have the ability to search for souls within a hundred kilometers through your mind 3 times, but it is limited to searching, and you can't interfere with the other party's soul."

Wei Gong's eyes were almost popping out, and his face was bitter, and he looked weak.

What the do I need a zombie sword for?

At this time, a "ding" sounded in my head.

"X067 is officially named [Zombie Sword], and the system has included it."
