Chapter 489 Blood Transfusion Verification Object in Black Crow Swamp (Bugfield Leader Adds 6 Updates)

Gretel was busy among the necromancers. Pointing fingers and giving orders constantly:

"The serum is on top! The red blood cells are on the bottom! Don't suck the serum on top too!"

"Don't be stingy with straws! Change them after you use them! Get another one!"

"First extend the straw into the test tube diagonally, then straighten it, and then insert it into the depth of the test tube before dripping! Don't touch the wall of the tube! It will all be wasted!"

"The temperature of the water bath is kept at 37 degrees, which is the same as the body temperature. If it is too cold, the red blood cells will condense! - Well, this is the blood of a dead person, and 37 degrees is not necessarily correct. In this way, bring in more water baths and adjust the temperature a few more times. temperature!"

It must be admitted that the magician's hands-on ability has surpassed that of a college student in his previous life, and is about the same as a master's student who has spent a year in the laboratory. And the Necromancer’s experimental level is the best among mages——

According to public opinion in the industry, only mages from the alchemy branch of the school of change can compete with them at the operational level.

Even so, Gretel still has many places to guide himself. The devil is in the details. Even in the simplest cross-matching experiment, there are seven, eight, or a dozen details that need to be paid attention to.

If it's even close, the result may not be achieved, or the result may be wrong...

Gretel stepped on his left foot and his right foot, and finally waited until the necromancers finished centrifuging, diluting, and adding the red blood cell suspension into the serum. He finally rushed forward impatiently and grabbed a syringe:

"Give it to me! Give it to me! While the mixture is about to incubate in the water bath, give me a tube first and let me take a look under the microscope!"

Blood that is darker than venous blood! Black, red, black and red, that color has caught up with blood clots! Taken directly from the blood vessels of corpses! It can still flow!

Woohoo, he must see for himself what the red blood cells of this blood look like under a microscope!

Gretel held his breath, dripped blood, pushed the film, and stained it. Adjust the objective lens, adjust the eyepiece...

can not see clearly.

Well, a dye that can dye red blood cells cannot dye the dead blood extracted from corpses...

Grete lowered his head in frustration and secretly decided to wait until today's experiment was completed and then check the paper to see if there was any experimental method for observing the morphology of red blood cells in corpses. On the right, a bottle of liquid has been handed over:

"Do you want dye? Or should we dye it for you? There are techniques for dyeing the blood of undead creatures. You can't just drop the dye on it -"

Seeing Gretel's somewhat surprised look, the necromancer smiled and said:

"Isn't it weird? It's been so long since you've built a microscope and seen all kinds of bacteria. Of course we'll use it to look around! That means staining is more troublesome. If you come a month later, you'll have to write a paper. published!"

Now that the paper has been written, Grete will not bother with drawing, and just take a look at it to satisfy his curiosity. Well, many red blood cells are still in shape and not broken. Maybe a cross-matching test can be done...

After all this fussing, the mixture was incubated in the water bath for enough time, and the results started to appear one after another:

"This group can't do it! They're all frozen!"

"This group too!"

"This group can't do it either! There's no coagulation!"

"This group..."

A dozen necromancers tried three plans each and were completely wiped out. They showed no regrets at all, discussed with each other, and immediately started a new round of experiments:

"No need for anti-coagulation spells! Anyway, all this blood has been processed!"

"Adjust the temperature again! Adjust it a few more times until it reaches freezing point!"

"Increase the proportion of negative energy!"

"Half of the people go out and do experiments with fresh blood! First get 100 people to draw blood and compare them to see how many blood types there are!"

When the experiment progressed to this point, Gretel simply handed over the leadership and sat aside to watch the necromancers do it. After two days of hard work, the first cheers came from the fresh blood experiment side:

"It's done! It's done!"

"There are four! There are four different kinds of blood. Either they will clot with each other, or one tube will clot! The same kind of blood, neither tube will clot!"

"You can write your paper now!"

"Publish a big article! This time I must publish a big article!"

"At least I can get a second work this time! - Research points! Contribution points! Rewards within the school!"

"I can finally be promoted to the third level Arcanist!"

"Try a blood transfusion! - No, Mr. Nordmark won't allow blood transfusion, then mix a large amount of the same type of blood and see if it will clot!"

Grete leaned against the experimental table, watching the necromancers cheering, and unconsciously smiled.

Even if he loses a little weight, his skin becomes a little sallower, and his temperament becomes a little gloomier, the Necromancer is still a human being, not a skeleton. The look of being happy is quite contagious. Moreover, the Necromancer celebrated with double excitement and double happiness——

Living people are responsible for shouting, cheering and singing, and running around the field holding test tubes. The skeletons are responsible for waving their arms, jumping, somersaulting, handstands, picking off their own heads, and throwing them around each other...

In addition to being unable to make any sound, it can be said to be an excellent atmosphere group. It is tireless and does not cry out in pain when it falls. It perfectly fills the gap of the Necromancer's weak athletic ability.

Gretel watched happily for a while, then withdrew his attention and began to study the blood in front of him. The previous round of troubles were all preparations. His real purpose was to develop blood testing magic.

100 samples, each one milliliter, are numbered. Someone has already divided them into four piles according to their blood types. Grete took a test tube, sucked a drop of blood, and released [Distinguish Bloodline]——

After he returned this time, he browsed through Thunder Horn's database and found an advanced version. This time the spell was cast, the information fed back by the magic was a bit more than the original version:

The owner of the blood is human, male. Power level, ordinary person.

Gone.

Gone……

Strange. Why can even the race be identified, but the blood type cannot be identified?

Gretel spread out his pen and paper and began to write and draw. Module a, module b, module c, module d...

When she went to the Dwarf Kingdom, Gretel had developed blood oxygen monitoring magic based on [Distinguish Bloodline] and had some experience in dismantling this magic. Now that I'm doing it, I'm very familiar with it.

At that time, he discovered that after removing the magic feedback unit, he would get a lot of messy messages. The feedback unit, in a sense, sorts out these messages, extracts a few fixed ones, and interprets the meaning for the caster:

For example, race: humans, elves, orcs, dwarves, mixed-race. The spell information Gretel read pointed out that it can also identify certain monsters and even dragons;

Gender: male, female (other races may have different genders);

Power level: civilian, and then from level one to level ten or above, it seems that it can be interpreted;

It's amazing that this spell can actually roughly distinguish whether it is a warrior or a spell caster...

There must be more messy information that it can't decipher, buried in the feedback!

And among these pieces of information, maybe one of them is about blood type?

In other words, I only need to find the point in all the information where the same blood type is exactly the same and the four blood types are different. The best thing is the section at the same position in the information flow——

Then, all the work begins with recording information!

Grete waved his fist to encourage himself and started to draw hard.

100 blood samples means 100 pieces of messy information, which should be recorded as accurately as possible. The more accurate the recording, the easier it is to compare, and the greater the possibility of finding the one he wants.

Come on, Grete!

He immersed himself in it. [Endless Ink Pen] flies up and down, dotted with stars, leaving messy ink dots, circles, arcs and various strips on the paper. Large and small, thick and thin, they look like urchins’ graffiti.

But of course, no one dares to take these smudges lightly. The necromancer who was watching saw him writing and drawing, and even took a long detour without even placing the skeleton there.

Gretel was immersed in recording, not knowing what night it was. After a long time, he heard someone next to him shouting:

"Mage Nordmark!"

"Mage Nordmark!"

"Gretel!"

Grete was startled and came back to his senses. Next to him, Archmage Grom seemed a little drier, with a layer of red light covering his dry and yellow face, and his tone was excited:

"The little guys did it! They successfully tested the blood type of the corpse!"

"……oh."

Grete blinked and smiled in line with the Archmage's expectations.

so what?

so what?

This kind of corpse has been dead for ten or eight years, but the blood can still flow. What if the blood type is tested?

I'm a doctor! I don’t want to change my career as a forensic scientist!

"After testing the blood type, they transfused blood with the corresponding blood type into the corpse, and the blood did not coagulate! Moreover, the vitality of the corpse has indeed improved!"

Archmage Grom was beyond excited. The preservation of corpses and the maintenance of their vitality have always been key issues for the Necromancy School. Everyone has tried transfusing living blood into corpses before, and most of it has coagulated. But now, Grete's discovery has solved this problem!

"Don't worry, this paper will be published in your name, and you have the final say as to who will be the second author! All the results belong to you!" Archmage Grom took over everything. In addition, in order to thank Grete, he also prepared an extra note:

"I contacted the Temple of the God of War, the City Guards, the Parliament Law Enforcement Team, and several surrounding armies. They all said that there have been no military operations recently, and the occasional training injury can be fully dealt with by the daily treatment force. But!"

Before Grete could ask, his voice suddenly rose:

"I thought of a place that definitely needs blood transfusion!"

"Where?"

"Mothers! - When giving birth, you will definitely lose a lot of blood! We only need to pick up the pregnant women in the workhouse and those receiving relief in advance, and give them blood transfusions when they give birth to their children, so that we can verify the theory of blood types. That’s right!”

Gretel's eyes lit up. Seeing that he agreed, the Archmage slapped his chest even more:

"If you agree, I will apply for the project now! Don't worry, the cost of supporting those pregnant women will be charged to Black Crow Swamp and not your money!"

By the way, I am thinking about a question: Do races without reproductive isolation, such as elves, humans and orcs, have the same blood types?
