Don't disturb the sorcerer's scientific research

This was something Jia Xiu had not expected.

But he is good at hitting hard.

"sure."

"Time is limited, so I won't talk too much. If you need anything, please let us know. We will do our best to express our gratitude."

"Nothing... No, there really is something. Can you make a spectrometer?"

He was also wondering what kind of light was lethal to vampires.

"A spectrometer is..."

In the following time, Jia Xiu briefly introduced what kind of instrument he needed and provided simple drawings.

After all, he hadn't learned much about drawing, and simple drawings were the limit of his ability.

"It should be possible to produce. We will complete it as soon as possible. It's a pleasure to work with you."

After saying goodbye to Uckermark's alchemy team, only Jashu, Mia and Arnold were left in the reception room.

Arnold suddenly bowed deeply.

"Thank you Master Mia and Mr. Jia Xiu for your help."

"We're just helping each other. There's no need to thank me. I hope your wish comes true."

"I also wish you good luck in that five-school competition."

"I'll take your good words..."

Chapter 105: Great Progress in Vampire Research

Uckermark's alchemy team, apart from anything else, is absolutely extremely efficient.

They made and sent over five sets of Jia Xiu's super imprecise version of the spectrometer within a week.

The alchemy team was commissioned because Ram was not good at making instruments with such high precision, and glass was his blind spot. The previous convex lenses were all made by Jia Xiu using glass rods.

The reason why there are five sets is because his drawings are not rigorous, so the alchemists added their own understanding and made improvements and adjustments. Also, because they were not sure what specific effect Jia Xiu wanted, they made five sets with different details.

Jia Xiu is not the only one who studies light. Some other scholars and spellcasters have also conducted research and discovered the dispersion phenomenon of light.

The biggest difference between Jia Xiu's needs and previous studies is that the small hole is replaced by a slit.

It stands to reason that this can improve accuracy, but Jia Xiu is not entirely sure. He has never studied optics and has only seen spectrometers from science stories.

Aurelius Mage Tower, in Jaxiu's laboratory.

Every window in the laboratory is covered with thick curtains, leaving only a small unobstructed area to let in sunlight.

The incoming sunlight is reflected by several plane mirrors and falls precisely on the slit of the spectrometer's parallel light tube.

In order to align it, Jia Xiu fiddled with it for almost two hours.

He also asked Ram to use the divine guidance spell on the spectrometer in advance. He didn't know if it would be useful, but he did it first.

The incident light passes through the compound lens in the parallel light tube and is refracted by the beam splitter, causing light of different frequencies to be separated due to different refractive indices. The deflection angle can then be determined by observing the mirror.

But Jia Xiu was not here to measure the deflection angle.

"Okay, let's try it."

There is also a vampire derivative in the laboratory who is here to cooperate with the experiment. She will see which angle of light blinds her, which will represent the wavelength of light that the vampires are afraid of.

The derivative didn't hesitate at all and aimed his eyes directly at the lens.

When Yan Ti first started participating in Jia Xiu's wonderful little experiment, he was quite nervous, not knowing what kind of cruel treatment he would suffer.

After coming here a few times, I completely relaxed. This job is much easier than going to work.

The damage suffered is far less than that suffered at work. There are too many ways for customers to go to the bathhouse to relieve stress by looking for vampire spawn. After all, the biggest feature that distinguishes them from other service places is that vampire spawn can basically not be killed as long as they are not exposed to the sun, and customers come here for this gimmick.

In comparison, Jia Xiu's experiment is quite refreshing.

The light has to go through such a complicated system, which weakens the intensity of the light a lot.

I really want to keep working here.

"Get ready. You should see a red light now. If you feel hurt, tell me immediately."

Jia Xiu hadn't finished speaking.

"what--"

The derivative screamed out loudly, and the sound sounded like pain mixed with excitement.

"So vampires are afraid of red light? What does it feel like?"

Jia Xiu asked hurriedly.

Without taking his eyes off the lenses, Yanti rubbed his hands awkwardly, "Actually, I'm not afraid of red light."

"Then what's your name?"

"I'm used to it at work. We have a rule that when we're operating, as long as the customer is there, no matter if it hurts or not, they must scream out to increase their excitement. If they don't scream, they'll be charged. So I feel bad."

"..."

Jia Xiu was silent for several seconds.

"You are quite professional then."

It turns out that the term "professional fake" has existed for so long.

"I, I will restrain myself. Please don't deduct my money."

It seems that this unlucky derivative is not doing well in his daily life and has his money deducted from him many times.

"It's okay, go ahead. Next, I'll rotate this axis and you'll see different colors of light. Once you determine which one causes harm, the experiment will be considered a success."

"Ok."

Jia Xiu started from red, turning it little by little, pausing for a few seconds after each turn to give her time to confirm.

However, even when it turned purple, the other party didn't react at all.

Not afraid of visible light?

Jia Xiu continued to turn.

"Uh...it hurts a little, but I can't see anything. It's probably about the same as burning my eyes with cigarette ash."

Does burning your eyes from cigarette ash just hurt a little?

OK, Hays' pain tolerance status has dropped one spot again.

Jia Xiu checked the range of rotation and confirmed that vampires were afraid of ultraviolet rays.

"I think I can handle it."

"good."

Jia Xiu continued to rotate the instrument. "Tell me when you can no longer feel the pain."

After turning a few more degrees, the derivative said, "I don't feel anything anymore."

Jia Xiu looked at the total rotation angle.

Although this instrument is not so precise that the exact wavelength cannot be calculated, it is estimated that it should be in the range of 200 to 400 nanometers.

Then the next goal was clear. The only thing he needed to become the vampire's father was a spell that could stably output ultraviolet light with a wavelength of 200 to 400 nanometers.

Wait! That vampire named Tatiana, dare to mark Bubu, wait until he climbs the technology tree again, and he will kill you!

After confirming that vampires were afraid of the light, Jia Xiu thought of another question.

So he asked, "Besides causing harm to you, does sunlight have any other effects?"

"Other effects? Who would have time to feel other effects after being exposed to sunlight?" the spawn replied. "Oh, no, it seems there are. When exposed to sunlight, we can't use vampire magic. For example, Ms. Carol couldn't transform into a blood bat and escape when exposed to the sun, but she could flash."

Can’t use vampire spells when being illuminated by light?

Jia Xiu immediately summoned the magic book and flipped through the vampire spells recorded on it, the very basic "Blood Shaping", which could shape anything that came into contact with blood into the desired shape.

It sounds powerful, but it's actually not very useful. Not only does it require contact with blood, but it also takes a while to guide it, and finally it creates a weapon or something, which is not as useful as a real weapon.

It is a very low-level vampire magic.

Even the low-level derivative in front of me can do it.

"Can you understand these runes?"

"Of course, such a simple spell can definitely be understood."

Jia Xiu brought a basin of duck blood and said, "Shape it."

"Shaped into what?"

"Um... a 4cm square, 1cm thick duck blood clot is ready."

The derivative began to cast a spell, and the duck blood slowly condensed into a cube.

"You stand in front of the spectrometer."

The derivative walked over, and the weak ultraviolet light shone on her, and the blood clot collapsed instantly. Just as she said, the blood clan magic could not be used.

"So what are you looking at these runes now?"

Jia Xiu has always suspected that different races have different perceptions of runes. When the vampires are exposed to light, their perception may become the same as that of humans, causing their original spells to become unusable. Now he wants to confirm which runes are being perceived differently.

However, the derivative gave an unexpected answer.

"still the same."

"Same?"

"However, I can determine which runes I channel now will be ineffective."

"Which?"

As the derivatives were pointed out one by one, Jia Xiu found the pattern.

The runes she pointed out, in his eyes, were the effects of "calling certain library functions."

A guess formed in Jia Xiu's mind.
