Chapter 523 Give the Blood Race a Taste of Sweetness First

What is the significance of blood type to blood race?
Gretel was momentarily confused.Make it clear, invite you to taste and study blood typing - you call it blood sampling - it is an exchange of benefits, okay!I will help solve the sun protection magic, and you will help with the blood test magic...

Now you ask like this, as if I'm taking advantage of you!

Before he could ask back, His Excellency the Archmage coughed and blinked his eyes.Gretel moved in his heart:
The ones helping him to develop it now are just a few young vampires, and the highest is no more than a viscount—in terms of magician level, that is, the highest level is no more than 9.If it can be proved that this magic is really useful for the blood race, maybe it can trick the boss into helping him?

Isn't it just nonsense to cheat research funds!
Look at me!
Gretel organized his words and looked up at the other party with confidence.Marquis Targu is a handsome man with profound features, short brown hair curled slightly on his forehead, dark complexion and gloomy expression.In Gretel's words, "It looks like I owe him a hundred thousand gold coins at any time—"

Now, the Lord Marquis stared at Gretel with a calm face of "negative one hundred thousand gold coins".Gretel didn't care, and raised a smile:
"Your Excellency the Marquis, yesterday I witnessed the process of identifying blood by several blood races, and I am very impressed with their abilities. ——I am also curious, what exactly does blood mean to blood races?"

This question is not difficult, especially for the disciple of the legendary mage, if he can't answer it, it can be regarded as a waste of effort.So Gretel didn't wait for the other party to answer, and went straight on:
"As far as I know, low-level vampires mainly feed on blood; high-level vampires can maintain their lives only by absorbing energy from the moonlight, and the main purpose of sucking blood is to increase the joy of life..."

This is common sense.So the Marquis of Targu kept his eyebrows fixed, with a face of "I'll listen to what you can say." Gretel continued to smile:

"So, as a healer, I have a question—"

Patient.Marquis Targu muttered something in a low voice, as if he had had some unpleasantness with this profession before.Gretel pretended not to notice, and asked with a smile:
"Why do you suck blood to ingest food instead of blood transfusion? Well, blood transfusion is—"

"I know what a blood transfusion is." Marquis Turgu interrupted suddenly.He frowned tightly, showing 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, it will consume more than half of the energy of a blood sucking—even All the energy is not enough!"

"It's probably because of the wrong blood type!" Gretel followed up and raised his voice:

"It's the same when we humans have blood transfusions. If the blood type matches, it will be beneficial. If the blood type does not match, there will be various adverse reactions and even death!"

"Hmm..." Marquis Targu pondered slightly.No approval, no questioning, and no rebuttal.Instead, Viscount Sebesh snorted softly:
"Then how do you prove it? Take our blood for an experiment? ——The true blood of the vampire is very precious!"

Gretel looked back into his eyes.After a moment of silence, he suddenly smiled:
"Blood transfusion technology may be more difficult to verify. So, let's start with something simple. Well, there is one thing I'm curious about—when vampires suck blood, why do they prefer arterial blood instead of venous blood?"

—Obviously the artery is deeper and harder to bite, isn't it?
His Excellency the Marquis smiled at this question, but did not answer.Beside him, Viscount Sebesh and another blood clan spoke in unison:

"Delicious! Fresher!"

"Full of vitality!"

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

"If there is a technology that can turn venous blood into arterial blood, or into arterial blood, are you willing to try it?"

This technique obviously hit the hearts of the blood races.Viscount Sebesh bowed slightly to His Excellency the Marquis, and ran away dragging Gretel.While running, he muttered:
"It would be best if it could be resolved!"

"Bite the artery is very troublesome. If you are not careful, you will bite through the vein at the same time!"

"And the newly developed descendants will never recognize blood vessels..."

"There are a few blood slaves I like very much. I am not happy to see them suffer!"

Gretel listened with his left ear and snorted with his right ear.Until Viscount Sebesh rushed into the room, raised his voice and called out:

"Theresa!"

A young girl came out from the next door.He was wearing a neat black robe, with a black veil on his head, and his hair was tightly wrapped under it, with no trace of hair color visible.The white scarf was spotless, and it was the standard attire for nuns of the Radiance Cult.

And on her greasy white neck, there was a black steel collar fastened tightly.

She curtsied.Viscount Sebesh pulled her wrist and handed it to Gretel:
"Come, take blood!"

"Don't live!" Gretel reflexively took a step back as if waking up from a dream:
"Don't use living people!—Have you any blood in store?"

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

Viscount Sebesh complained in a muttering tone, a bit like Gretel complaining, "Why do you eat compressed biscuits when there are fresh vegetables?"Gretel shook his head resolutely, and looked at the girl who was pulled out by him:
The sleeves of the nun's gown are wide, and once the arms are pulled up, the sleeves will naturally fall back, revealing half of the smooth forearm.Even though Viscount Sebesh had let go of her palm, she still lowered her eyes, kept her arms stretched out, palms up, and remained motionless.

The blood slave girl's face was numb, neither sad nor happy, not even the slightest bit of fear.That look, it seemed that his wrist, his blood, and even his entire body had nothing to do with him.

However, Gretel has no way to treat it as irrelevant.Even if this is a nun of the Radiance Religion, the positions of the two sides may be hostile, even if she is a slave of the blood clan, as a diplomat, it is impossible for him to rescue her——

But, at least she is human.

It's a person, not an animal, or an experimental product that can be used to draw blood casually.

Gretel even took a diagonal step, blocking Teresa behind him, facing Viscount Sebesh:

"Either use the stored blood, or follow me to the Tower of Sleepless!"

Well, go to the Black Crow Swamp to collect experimental materials, you can always get it...

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

The two confronted each other silently.Gretel raised his head and stretched out his arms to block the blood slave girl, not giving an inch.For a long time, Viscount Sebesh shrugged, passed Gretel, and waved to his blood slave:

"Teresa, go down!"

The blood slave girl curtseyed and retreated silently.He retreated to the door, raised his gaze, and glanced at Gretel:
There was a flash of light in this glance, fear mixed with gratitude, and gratitude mixed with fear and hatred.The next moment, she lowered her eyes again, calmly, and walked out like a puppet.

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

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

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

The dark red stored blood that was visible to the naked eye gradually turned bright red.

Well, the extracorporeal oxygenation of the artificial lung, although the material is very troublesome, it needs to be tossed with semi-permeable membranes, polymers that imitate cell membrane structures, and the like to protect the blood components from being destroyed.But now it’s processed for the vampires to drink anyway, it’s almost worth it...

"Drink a sip?"

"I drink?"

"Nonsense, or should I drink it?"

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

"Not bad! It works! It's much better!"

Alas, for blood race like them, when they are traveling, it is not easy to carry blood slaves with them, and when they are hidden, it is very uncomfortable to drink stored blood... Now it is good, at least it can be processed, and it will be full of vitality. Hot blooded!
