In the sword-forging room, the fire was stirring, and Wei Gong was sweating profusely, and took out a piece of cast sound from the mold.

This sounding piece, about the size of a thumb and about half a centimeter thick, was hung on the audition stand by Emiya, like a short piece of bacon.

He picked up the fire system true qi and slowly urged it.

The sounder made a high-pitched sound.

Emiya tested it through the system, and it had reached the number of hertz he needed, which was a drop la.

If you want to separate the musical function of the Wing Qin Sword from its attribute transformation function, it means that Wei Gong will have to find the corresponding materials and create seven special wing swords.

For this reason, he is trying to improve the Winged Qin Sword, hoping to make a Winged Qin Sword that can completely trigger all scales with only a single series of True Qi.

However, in this way, the difficulty is much more difficult than building a compound sword, and it almost increases exponentially.

On the one hand, it is necessary to do various screening and experimentation of materials in order to be able to create materials of the same series and perfectly produce the same timbre sound.

On the other hand, on the basis of ensuring the basic function of the sword, the cost of materials should be reduced as much as possible, and the assembly of a sword can be completed at the smallest price.

But both of these questions are very difficult.

First of all, the first question, as we all know, in the same frequency vibration, the sound made by steel and the sound made by wood are different, the metal is thick and textured, and the wood is crisp and has a good continuation effect.

Similarly, the cold jade steel used in the ice system and the warm yang steel used in the fire system, even if it seems that the hardness and density of the material are not much different, but because of the different systems, the sound emitted is also slightly different, the cold jade steel is crisp, and the warm yang steel is soft.

Therefore, just considering the choice of materials consumed almost all of Wei Gong's mental energy.

Even the most basic tonal challenges can't be overcome, let alone cost reductions.

For this matter, Emiya was so busy that in less than two days, his casting room was filled with all kinds of materials, and for this he also spent all the 2 million that Kenrin Sakura gave him.

There is no way, Wei Gong can only prepare to test this batch of materials, and then ask Jian Rin Sakura for it, but judging from all indications, the eldest princess of the Dream Sword Kingdom does not seem to have much savings.

When the time comes, let's see if any employers are willing to pay a deposit first, otherwise this business will not be easy to do.

Thinking of this, a wry smile appeared on the corner of his mouth, shook his head, and then nervously placed the freshly baked fire material of the falling sound piece into another rectangular wooden box.

In order to test the different effects of its sound, Emiya specially created vessels of different materials.

After listening for a while, Wei Gong only felt a headache.

Although the frequency is correct, it is very difficult to match the sound of the Tsubasa sword used by the sword Rin Sakura.

And, the more you listen, the more confused your brain becomes.

Damn it......

Sure enough, I have to invite a music professional to come, and it's best to have an absolute sense of tone, such as Ken Rin Sakura, otherwise if I continue to listen to it like this, I will have a psychological shadow on the sound for the rest of my life......

"Hey, may I ask a question?"

At this moment, Cui Xiaoxiao's voice sounded behind her, she was wearing an aqua blue puffy skirt, and then slowly walked in front of him with big eyes.

Emiya glanced up at her impatiently, "Didn't you see that I was busy?" ”

Cui Xiaoxiao didn't care about him, and said to herself, "What does it mean in the introductory chapter of cultivating immortals that people are the chief of all spirits, born with spirits, and if they have spirits, they can control all things?" ”

Emiya gave her a big roll of the eye, didn't she say I was busy?

He sighed, then turned and walked over to another freshly cast water-based sounder.

The meaning of this sentence is that man is the chief of all souls, so there is no need to translate this, right? Compared with animals or something, people are very spiritual, because people can recognize the world and change the world, and will invent and create, and in the world of fairy swords, everyone is born, and there is something called spiritual veins in the body, which can perceive the ubiquitous [aura] in the world, and reiki is a thing that cannot be seen or touched, but it is the root of all spirits, so if you can correctly master the guidance method of aura, then you will be able to control everything. ”

Wei Gong explained, while clipping the water system sound film into the wooden sound box, and then slowly urging the true qi in the body.

The sounding piece made a crisp sound.

"See, I just used to mobilize the true qi to trigger the vibration of this water system sound piece, which is the most basic [Imperial Spirit] method."

"So, this [aura] may be a kind of dark matter?" Cui Xiaoxiao groped her chin, and then raised her head after a while, "No, according to what you said, a person has [spiritual veins], and he can sense the ubiquitous aura through the spiritual veins, so why can't I feel it?" ”

"How do I know yours? Get out of the way, it won't be good to burn you later. ”

Emiya threw a new piece of metal into the furnace, and luck set the fire on fire.

"But some people are like this, entering the stage of consciousness will be later than normal people, generally speaking, it will be about three to four years old to have the first perceptual behavior, you are only four years old now, and it is normal that you do not come."

"You're supposed to be a great aunt?" Cui Xiaoxiao said dissatisfied.

"Yes, as your body develops, the Great Aunt will always come, and the first [Soul Consciousness] will also come. Moreover, the traverser itself has to have an adaptation process. ”

Cui Xiaoxiao was dumbfounded by him, but she didn't plan to walk away immediately.

"By the way, you just mentioned [Knowing Spirits], and I also saw this paragraph, so what do the five stages of entry mentioned here, Knowing Spirits, Turning Spirits, Building Spirits, Gathering Spirits, and Imperial Spirits, mean?"

"Uh......" Emiya turned around with his shoulders drooping and looked at her suspiciously, "Ah, hey, what the hell are you going to do?" So many weird questions asked today. ”

Wei Gong also felt that something was not right, what this girl asked, aren't they all things that are talked about in the basic chapter of cultivating immortals, could it be that Cui Xiaoxiao's brain was caught by the door, and she actually wanted to cultivate immortals?

Hasn't she always been against this occult thing?

"You care about me?" Cui Xiaoxiao glanced at him, and then said lightly, "I'm studying." ”

Hold the grass, is there a mistake?! Cui Xiaoxiao is really cultivating immortals?

Wei Gong hurriedly looked out the window-

It's the sun coming out in the west, right?
