Chapter 523 Let’s Give the Vampires a Little Sweet Taste First

What does blood type mean to vampires?

Gretel was confused for a moment. Understand, inviting you to taste and study blood typing - you call it blood testing - is an exchange of interests, right? I help solve the sun protection magic, and you help research the blood test magic...

Now that you are asking this, it seems like I am taking advantage of you!

Before he could ask a question, the Archmage coughed and blinked. Grete's heart moved:

Currently, the ones helping him develop are just a few young vampires, the highest of which is no more than a viscount - in terms of magician level, the highest is no more than level 9. If it can be proven that this magic is indeed useful for vampires, maybe it can trick the boss into helping?

Isn’t it just nonsense to defraud research funds?

Look at me!

Gretel organized his words, and with confidence, he raised his head and looked directly at the other person. Marquis Turgu is a handsome man with profound features, short brown hair slightly curled on his forehead, dark complexion, and a gloomy expression. In Grete's words, "It looks like I owe him one hundred thousand gold coins at any time——"

Now, the Lord Marquis stared at Grete with a calm face that said he was "negative of one hundred thousand gold coins." Gretel didn't care and raised a smile:

"Your Majesty the Marquis, yesterday I witnessed the process of several vampires identifying blood, and I admired their ability very much. - I am also very curious, what does blood mean to vampires?"

This question is not difficult, especially for the disciples of the legendary mage. If you can't answer it, it can be regarded as a lack of effort. So Gretel didn't wait for the other party to answer, and continued:

"As far as I know, low-level vampires mainly feed on blood; high-level vampires can maintain their lives by simply absorbing energy from the moonlight. The main purpose of sucking blood is to increase the fun of life..."

This is common sense. So Marquis Turgu kept his eyebrows motionless and said, "I'll listen to what you have to say." Grete continued to smile:

"Well, as a healer, I have a question-"

Patient. Marquis Turgu muttered something in a low voice, as if he had had trouble with this profession before. Grete pretended not to notice anything and asked with a smile:

"Why do you consume food by sucking blood instead of transfusing blood? Well, blood transfusion is-"

"I know what blood transfusion is." Marquis Tergu suddenly interrupted. His brows were knitted together, revealing a deep vertical line:

"Do you think we haven't tried it? Direct blood transfusion is indeed much more efficient, but it is more likely to cause problems. Sometimes, just to suppress the uncomfortable feeling, most of the energy of a blood meal will be consumed - even All the energy is not enough!”

"That's probably because the blood type is wrong!" Grete followed up and said:

"The same goes for us humans when we transfuse blood. If the blood type matches, it will be beneficial. If the blood type does not match, various adverse reactions will occur, and even death!"

"Hmm..." Marquis Tergu pondered slightly. There was no agreement, no questioning, and no rebuttal. On the other hand, Viscount Sebesh snorted softly:

"Then how do you prove it? Take our blood for experiments? - The blood of the Vampires is very precious!"

Gretel turned and stared into his eyes. After a moment of silence, he suddenly smiled:

"Blood transfusion technology may be difficult to verify. So, let's do something simple first. Well, there is one thing I'm curious about - when vampires suck blood, why do they prefer arterial blood to venous blood?"

——The arteries are obviously deeper and harder to bite, right?

To this question, His Excellency the Marquis smiled but did not answer. Beside him, Viscount Sebesh and another vampire said in unison:

"It tastes great! Fresher!"

"Full of life!"

vitality? Gretel rolled his eyes. The main difference between arterial blood and venous blood is the oxygen-carrying capacity of hemoglobin - ignoring carbon dioxide, urea and other waste products. so……

"If there was a technology that could turn venous blood into arterial blood, or something close to arterial blood, would you be willing to try it?"

This technology obviously touched the hearts of the vampires. Viscount Sebesh bowed slightly to His Excellency the Marquis, dragged Gretel and ran away. As he ran, he muttered:

"It would be best if we can solve it!"

"It's very troublesome to bite the artery. If you're not careful, you will bite the vein at the same time!"

"And the newly developed descendants always don't recognize blood vessels..."

"There are a few blood slaves I like very much. Seeing them suffer makes me unhappy!"

Grete listened with his left ear and erupted with his right ear. Until Viscount Sebesh rushed into the room and raised his voice and shouted:

"Teresa!"

A girl came out from next door. Wearing a neat black robe, with a black gauze on his head, his hair was tightly wrapped underneath, and no hair color could be seen at all. The white scarf is spotless, the standard attire of the nuns of the Glorious Cult.

And on her white neck, there was a black steel collar that fit tightly.

She curtsied. Viscount Sebesh took her wrist and handed it to Gretel:

"Come, take blood!"

"No living people!" Gretel suddenly woke up from a dream and took a step back reflexively:

"No live ones!—Have you any blood in store?"

"Why would living people eat stored food..."

Viscount Sebesh's grumbling complaint was a bit like Gretel's complaint, "Why should we eat compressed biscuits when there are fresh dishes?" Gretel shook his head firmly and looked at the girl he pulled out:

The sleeves of the nun's robe are wide. As soon as the arms are pulled up, the sleeves naturally fall back, revealing half of the smooth forearm. Even though Viscount Sebesh had let go of his hand, she still lowered her eyes and kept her arms stretched out with her palms upward, motionless.

The blood slave girl's face was numb, without any sadness or joy, and she didn't even have the slightest fear. That look made it seem as if his wrist, his blood, and even his entire body had nothing to do with him.

However, there was no way Gretel could treat it as irrelevant. Even if this is a nun from the Glorious Cult, and the two sides may be hostile, even if she is a slave of the Vampire Clan, as a diplomat, it is impossible for him to rescue her——

But, she is at least human.

It's a human being, not an animal, and it's not an experiment that can be used casually to draw blood.

Gretel even took a step diagonally, blocking Theresa behind him, and faced Viscount Sebesh:

"Either use the stored blood, or come with me to the Tower of Sleeplessness!"

Well, if you go to Black Crow Swamp to collect experimental materials, you can always get them...

Viscount Sebesh was helpless. It's not easy for him to subdue Gretel or use mental control to make him work - even if he could, with so many great magicians coming and going, this is not a place to do bad things!

The two faced off silently. Gretel held his head high, stretched out his arms to block the blood slave girl, and refused to give an inch. After a long while, Viscount Sebesh shrugged, passed Gretel, and waved to his blood slave:

"Teresa, go down!"

The blood slave girl curtsied and retreated silently. He retreated to the door, raised his eyes, and glanced at Grete:

This glance was full of waves, fear mixed with gratitude, gratitude mixed with fear and hatred. The next moment, she lowered her eyes again and walked out calmly, like a puppet.

Gretel didn't look back until she disappeared. Opposite him, Viscount Sebesh raised his eyebrows at him, patted the space bag, and threw out a bag of blood:

"Okay, are you satisfied? - Can you try it for me now?"

Just give it a try. Gretel set up the test tube, used the alcohol lamp, and began to heat potassium permanganate. Introduce heated oxygen into the beaker containing blood and let the tube bubble at the bottom of the beaker...

Visible to the naked eye, the dark red stored blood gradually turns bright red.

Well, the extracorporeal oxygenation of artificial lungs, although the materials are very troublesome. What kind of semi-permeable membranes, polymers that imitate cell membrane structures, etc. are required to protect blood components from being destroyed. But now it’s processed and given to vampires to drink, so that’s pretty much it...

"Drink a sip?"

"I drink?"

"Nonsense, otherwise why should I drink?"

Viscount Sebesh muttered and reluctantly picked up the beaker. After taking a sip, his eyes immediately lit up and he gave Gretel a thumbs up:

"Not bad! It works! It tastes much better!"

Alas, when vampires like them travel, it is difficult to carry blood slaves with them, and they have to pay attention to concealment, it is very uncomfortable to drink stored blood... Now it's better, at least they can process it and drink it full of vitality. Hot-blooded!
