It's not that hard to open a hospital in another world, right?

Chapter 520 UV Protection Magic vs Blood Test Magic?

The lights flickered.

Gong chips are staggered.

At the dinner party, there was laughter and laughter.

Gretel yawned painfully.

...so why am I staying up all night?Why was there so many friends around, but I was assigned the task of receiving blood clans?Why can't I chat with dwarves, barbarians, orcs?
Bloodlines cannot see the sun.Although dwarves are not afraid of sunlight, they are more adaptable to the dark environment underground.Among the orcs who visited this time, those with higher status—such as tiger people, lion people, and leopard people—also adapted to the night without any hindrance.

The result of taking the greatest common divisor is that human beings who do their best to be landlords have to work hard to stay up late.

Look to the left, look to the right, the magicians around are mostly disheveled.Magicians in this world are used to going to bed early and getting up early, sleeping on time to restore their mental strength.It's not impossible to make them stay up late and work overtime, but it's really painful.

"Mr. Nordmark, are you tired? Are you going to rest?"

The guests around asked with a smile.He was holding a crystal clear goblet, in which the crimson liquid was rippling with light and shadow, and the aroma of the wine was tangy.Although Grete could smell the bloody smell as soon as he took a look at it...

Speaking of which, why do the blood race like to mix wine with blood, correct, mix blood with wine.

It's not that Gretel doesn't understand this way of drinking. In his opinion, it's no different from mixing red wine with Coke and white wine with Sprite in his previous life. It's nothing more than a taste.However, the problem is that alcohol must be mixed with hemoglobin...

Gretel saw it and wanted to give him a Lonatone.

"Oh, no, I'm not tired yet, Mr. Sebesh." Gretel shook his head earnestly and continued to fulfill his diplomatic mission.At the same time, control yourself to focus your eyes on the other person's face, and resolutely don't look down:

Hell, why do I see gorgeous lace embroidered with gold thread, puffy lace cuffs, silk stockings, leggings, and high heels on a man—even a blood race—at the same time?
"Let's continue, where did we just say? Ultraviolet light?"

"Yes, that's right, ultraviolet light." The blood race named Sebesh raised his glass with a smile, saluted Gretel, and took a sip.The liquid in the cup dyed a deep red on his pale lips, making his complexion even more seductive:
"Master Nordmark, you are really a genius... After reading your thesis, we separated the components of ultraviolet rays in the holy light and measured its energy..."

"You study Holy Light?!"

Gretel was startled.Strigoi, undead creatures, the Holy Light can kill them twice!What kind of spirit is it to study the Holy Light with such a wound? !

"Of course, it's just the holy light. Just grab a few holy objects, or kidnap a few priests, and you'll have everything."

Saibesh was calm and breezy, as if he just said a trivial matter.Although Gretel knew that the conflict between the blood race and the glorious Holy See was not a day or two:

In the land occupied by the blood race, in the east of the Rhine Kingdom, there is a huge black forest with luxuriant branches and leaves, and there is no sunshine all year round.Because of the special geographical conditions, there are countless unique species growing on that land, many of which are magic materials specially needed by the council.

Every year, a large number of hunters and herbal gatherers go to the Rhine Kingdom to search for treasures.Bloody conflicts between the people under the blood clan and the glorious Holy See occurred from time to time.

"Back to the topic, according to calculations, the ultraviolet light contained in the holy light of the glorious Holy See is more than twice that of sunlight, so it can cause stronger damage to us. Based on this principle, our great Earl has developed a Very effective protection against magic."

Wow.

Defense · protection · magic · law.

I only know physical protection, that is, UV protective clothing, protective face shield, protective glasses; and chemical protection, such as applying sunscreen with UV absorption function.Actually, you can still use magic sunscreen?
Gretel's eyes lit up.Before asking, a lady with light golden curly hair floated over in the fragrant wind.Although she was indoors, she was also holding a small lace umbrella, her eyes flickered:

"Yeah, protective magic... the protective magic that uses silver powder as the material... I don't know how many people can be burned to death before the protection takes effect?"

"Julia!"

Sebesh roared.Yulia covered her mouth with a silk handkerchief, giggled, her skirt brushed past the two of them, and floated away.Mr. Sebesh watched her back for a while, then smiled helplessly:
"Hey, let me show you a joke. Yulia's family has always been difficult to get along with our family. Fortunately, you are a friend of the blood family - there is no need to deny that you revealed the existence of ultraviolet light, which is very important to us. As for the shortcomings of this magic, I am here this time to hope that you can participate in the improvement."

Gretel was speechless.

Well, we all know that silverware, silver crosses, silver bullets—if there are bullets in this world, and silver holy water are powerful against undead creatures.

A certain earl on your side thought of using silver as a means of protecting against ultraviolet rays. Should I say that he is a bold man with high skills, or that his brain is as big as a black hole?

He blurted out:

"Your magic, the material used is silver powder, no, silver nitrate? Or some compound of silver? It absorbs ultraviolet rays and constitutes protection, right? The principle of this magic is like this!"

"Yes, yes!" Sebesh nodded repeatedly.Gretel struggled for a moment:
If silver compounds can be used to absorb ultraviolet rays and form protection, then other materials can also be used... By the way, what materials are those cosmetics made of...

Ethylhexyl salicylate?
Homosalate?

Isopentyl p-methoxycinnamate?

Benzophenone-3, Benzophenone-4?

Gretel struggled to recall the ingredient list on the cosmetic box in her previous life.He only recalled a few kinds, and he gave up this technical route:
With the current level of technology in this world, it is estimated that none of the above can be synthesized.

So... what to replace?

What chemical has the strongest ability to absorb ultraviolet rays?Silver bromide?Nano silver?No, it's too cruel to let the blood race to toss silver, or else... ozone?
What is the industrial synthesis method of ozone?
It seems that using strong current and oxygen can produce ozone... For the specific method, maybe you should ask the teacher...

Gretel lowered his eyes and thought for a moment, raised his eyes, and stretched out his hand to Mr. Celia:

"I have some ideas, but the details still need to be studied and tested. —— Then, I am very happy to participate in your research."

"Great!" The pale and cold palm of the young vampire grasped Gretel's right hand, shaking it vigorously up and down:

"Any price, you just have to mention it! Blood clans are always generous to their friends, do you need gold, jewelry, or a beautiful virgin?"

"...I hope that you, of course, your friends are willing to come together, that's the best, to participate in my research and development of a magic, about how to identify blood..."

"That's no problem! I'm the best at identifying blood!"
