Chapter 518: Give the Vampires a little sweet taste first
What does blood type mean to a vampire?
Grete was confused for a moment. To understand, please come and taste and study blood typing. You call it blood tasting, which is an exchange of interests! I will help solve the sun protection magic, and you will 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. Gretel's heart moved:
The ones currently helping him develop it are just a few young vampires, the highest of which is no more than Viscount. In terms of magician level, the highest level is no more than level 9. If it can be proven that this magic is indeed useful for vampires, maybe it can trick the big boss into helping?
Isn’t it just nonsense to defraud research funds?
Look at me!
Grete organized his words, confidently, and looked up at the other person. Marquis Turgu was a handsome man with profound features, short brown hair slightly curled on his forehead, dark complexion, and a gloomy expression. In Grete's words, he could "come at any time"
It looks like I owe him 100,000 gold coins."
Now, the Lord Marquis stared at Grete with a calm face that said he was "negative of one hundred thousand gold coins." Grete 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 curious, what does blood mean to vampires?"
This question is not difficult, especially for the disciples of the legendary mage. If they can't answer it, it can be regarded as a waste of effort. So Gretel did not wait for the other party to answer, and went on:
"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 unmoved and said, "I'll just listen to what you have to say." Grete continued to smile:
"Well, as a healer, I have a question."
The healer, Marquis Turgu, muttered something in a low voice, as if he had had some unpleasant experiences with this profession before. Gretel pretended not to notice anything and asked with a smile:
"Why do you consume food by sucking blood instead of blood transfusion? Well, blood transfusion is"
"I know what blood transfusion is." Marquis Tergu suddenly interrupted. His brows were furrowed, with a deep vertical line showing:
"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 or even all of the energy of a blood meal will be consumed
It’s not even enough!”
"That's probably because the blood type is wrong!" Grete followed up and raised his voice:
"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 Turgu pondered slightly. He did not agree, question or refute. On the contrary, Viscount Sebesh snorted softly:
"Then how do you prove it? Take our blood for experiments? The blood of vampires is very precious!"
Grete turned her head and stared into his eyes. She was silent for a moment and then suddenly smiled:
"Blood transfusion technology may be difficult to verify. So, let's do something simple first. Well, one thing I'm curious about is why vampires prefer arterial blood to venous blood when they suck blood?"
Obviously the artery is deeper and harder to bite, right?
The Marquis smiled at this question and did not answer. On the contrary, beside him, Viscount Sebesh and another vampire said in unison:
“Tastes great! Fresher!”
“Full of life!”
Vitality? Gretel rolled his eyes. The main difference between arterial blood and venous blood is that the oxygen-carrying capacity of hemoglobin ignores carbon dioxide, urea and other waste products. So...
"If there is a technology that can turn venous blood into arterial blood, or into something close to arterial blood, would you be willing to try it?"
This technique obviously touched the hearts of the vampires. Viscount Sebesh bowed slightly to 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!"
Gretel listened with his left ear and listened with his right ear. Until Viscount Sebesh rushed into the room and raised his voice and shouted:
"Teresa!"
A girl came out of the next door. She was wearing a neat black robe, with a black gauze on her head. Her hair was tightly wrapped underneath, and there was no trace of hair color. The white scarf was spotless, and it was the standard dress of the nuns of the Guanghuang Cult.
.
And around her pale white neck, a black steel collar was fastened tightly.
She curtsied and saluted. Viscount Sebesh took her wrist and handed it to Grete:
"Come, take blood!"
"No living people!" Gretel suddenly woke up from a dream and took a step back reflexively:
"Don't use a living person! Do you have any blood in storage?"
"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 vegetables?" Gretel shook his head firmly and looked at the girl he had pulled out:
The sleeves of the nun's robe were wide, and as soon as her arms were pulled up, the sleeves naturally fell back, revealing half of her smooth forearms. Even though Viscount Sebesh had let go of her hands, she still lowered her eyes and kept her arms straight.
The posture with the palms upward is motionless.
The blood slave girl's face was numb, without sadness or joy, and she didn't even have the slightest fear. That look seemed as if her wrist, her blood, and even her entire body had nothing to do with her.
However, there was no way for Gretel to treat her as irrelevant. Even if this was a nun from the Glorious Cult, the two sides might be hostile, and even if she was a slave of the vampire clan, as a diplomat, it was impossible for him to rescue her.
But at least she is human.
It is a human being, not an animal, and it is not an experiment that can be used casually to draw blood.
Grete even took a step diagonally, blocking Theresa behind him, and faced Viscount Sebesh:
"Either use the stored blood, or follow 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 was difficult for him to subdue Gretel, nor to use mental control to make him work. Even if he could do it, there are so many great magicians coming and going, so 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 time, Viscount Sebesh shrugged, passed Gretel, and waved to his blood slave:
"Teresa, go down!"
The blood slave girl curtsied and retreated silently. She retreated to the door, raised her gaze, and glanced at Gretel:
This glance was filled with 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 her figure 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. Grete set up the test tube, turned on the alcohol lamp, and began to heat potassium permanganate. He introduced the 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, including semi-permeable membranes, polymers that imitate cell membrane structures, etc., to protect blood components from being destroyed. But now it is processed for vampires to drink.
, almost done...
"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!
