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

Chapter 489 The Blood Transfusion Verification Object in the Black Crow Swamp (Bugfield Leader Plus 6)

Gretel scurry among the necromancers.Pointing fingers and giving orders continuously:
"Suck the serum on the top! Suck the red blood cells to the bottom! Don't suck the serum from the top!"

"Don't be stingy with straws! Replace them after you've used them! Get another one!"

"The straw is first inserted into the test tube at an angle, then straightened, and then dipped into the depth of the test tube! Don't touch the wall of the tube! It's all wasted!"

"Keep the temperature of the water bath at 37 degrees, which is the same as the body temperature. If it is too cold, the red blood cells will condense! ——Hey, this is the blood of a dead person. 37 degrees may not be correct. In this way, bring more water baths and adjust them a little more. 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 been tossing in the laboratory for a year.And the experimental level of the necromancer is even the best among the necromancers——

According to the consensus 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 a lot to direct personally.Details are the devil. Even for the simplest cross-matching experiment, there are seven or eight or a dozen details that need to be paid attention to.

Just a little bit, maybe the result can't be made, maybe the result can be wrong...

Gretel stepped on his right foot with his left foot, and stepped on his left foot with his right foot. It was very easy for the necromancers to finish centrifuging, diluting, and putting the red blood cell suspension into the serum.He finally rushed forward impatiently and grabbed a needle:
"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 red, that color, caught up with the thrombus!It was drawn directly from the blood vessels of the corpse!It can still flow!
Woohoo, he must see for himself what the red blood cells look like under a microscope!

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

can not see clearly.

Uh, the dye that can dye red blood cells cannot be dyed with the dead blood drawn from this kind of corpse...

Gretel bowed his head in frustration, secretly decided to wait until today's experiment was finished, and then look up the papers to see if there was an experimental method to observe the shape of red blood cells in the corpse.On the right hand side, a bottle of liquid has been handed over:

"Do you want dye? Or should we dye it for you? There is a skill in dyeing the blood of undead creatures. You can't just drop the dye on it—"

Seeing that Gretel was a little surprised, the necromancer smiled and said:

"Is it strange? You have been making out the microscope for so long, and you have seen all kinds of bacteria for so long. Of course we will use it to look around! That is to say, staining is more troublesome. If you come a month later, the paper will have to published!"

Now that the thesis has been written, Gretel doesn't bother drawing pictures, just take a look for himself to satisfy his curiosity.Well, many red blood cells are still in shape and have not been broken. Maybe a cross-match test can be done...

And after this tossing, the mixture was incubated in the water bath for enough time, one after another, and began to produce results:

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

"This group is too!"

"This group is not good either! There is no condensation!"

"This group..."

A dozen or so necromancers tried three schemes per person, and the entire army was wiped out.They didn't feel frustrated at all, they discussed with each other, and immediately started a new round of experiments:
"I don't want anticoagulation! Anyway, the blood is all processed!"

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

"Increase the proportion of negative energy!"

"Split half of the people out and use fresh blood for experiments! Get 100 people to draw blood first, and compare them to find out how many blood types there are!"

The experiment progressed to this point, Gretel simply handed over the leadership, sat by the side, and watched the necromancers do it.After two days of tossing, on the side of experimenting with fresh blood, cheers came first:
"It's done! It's done!"

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

"You can write a thesis!"

"Post a big one! This time I must post a big one!"

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

"Finally you can become a third-ring Arcanist!"

"Try a blood transfusion! No, Mr. Nordmark won't allow blood transfusion, then mix a lot of the same kind of blood and see if it clots!"

Gretel leaned against the experimental table, watched the Necromancers cheering, and unknowingly evoked a smile.

Even if he lost a little weight, his skin became sallow, and his demeanor became gloomy, the necromancer was still a human being, not a skeleton.The look of being happy is still quite contagious.And, the Necromancer celebrated, double the excitement, double the joy—

The living people are responsible for shouting, cheering and singing, and flying around the field holding test tubes.The skeletons are responsible for waving their arms, jumping, flipping, standing on their heads, taking off their heads, and throwing each other...

In addition to being unable to make a sound, it can be described as an excellent atmosphere group. It is tireless and does not cry out in pain when it falls. It perfectly fills in the blank 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 tossing was all preparatory work, and his real goal was to develop blood test magic.

100 samples, one milliliter each, have been numbered.Someone has already divided them into four piles according to their blood types.Gretel took a test tube casually, sucked a drop of blood, and released 【Discern bloodline】——

After he returned this time, he browsed through the database in the Horn of Thunder and found an advanced version.This time, the magic feedback information is more than the original version:
The master of blood is human, male.Power level, normal people.

Gone.

Gone……

Strange.Why can even the race be identified, but not the blood type?
Gretel spread out the pen and paper and began to write and draw.module a, module b, module c, module d...

When he went to the Dwarf Kingdom, Gretel had developed the blood oxygen monitoring magic based on [identify bloodlines], and had some experience in dismantling this magic.Doing it now can be said to be familiar with the road.

At that time, he discovered that after removing the magic feedback unit, he would get a lot of messy news.And the feedback unit, in a sense, sorts out these messages, extracts a few fixed ones, and interprets the meaning for the caster:
For example, races: human, elf, orc, dwarf, hybrid, the spell information that Gretel read pointed out that it can also distinguish certain monsters, and even dragons;

Gender: male, female (other races may have different genders);
Strength level: civilians, and from level one to level ten above, it seems that they can understand it;
It's amazing that this spell can roughly tell whether it's a warrior or a spellcaster...

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

And among these pieces of information, there might be one, which is about blood type?

That is to say, I just need to find the spot where the same blood type is exactly the same but the four blood types are different among all the information.Preferably, it is the section in the same position in the information flow——

Then, all the work starts from recording information!

Gretel pumped his fists to cheer himself up and began to draw.

100 blood samples means 100 pieces of messy information, which should be recorded as accurately as possible.The more accurate the memory, the easier the comparison, and the more likely it is to find the one he wants.

Come on, Gretel!
He immersed himself in it. 【Endless Ink Pen】flying up and down, dots, leaving messy ink dots, circles, arcs and various bars on the paper.Big and small, thick and thin, like urchin graffiti.

But of course, no one dares to take these smears lightly.The necromancer who was watching saw him writing and drawing, and even made a detour, not even putting the skeleton there.

Gretel buried himself in the record, not knowing what day and night it was, but after a long time, he heard someone beside him yelling:
"Master Nordmark!"

"Master Nordmark!"

"Grete!"

Gretel was shocked and came back to his senses.Beside him, the Archmage Grom, who seemed to be a little more dry, had a red light on his dry and yellow face, and his tone was excited:

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

"……Oh."

Gretel blinked his eyes and showed a smile that met the archmage's expectations.

So?

So?

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

I am a doctor!I don't want to change my job as a forensic doctor!

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

Archmage Grom couldn't be more excited.The preservation of corpses and the maintenance of vitality of corpses have always been the key problems of the Necromancy School.In the past, everyone tried to infuse living blood into corpses, and most of them were coagulated, but now, Gretel's discovery has solved this problem!

"Don't worry, this paper will be published under your name, and whoever counts as the second author has the final say! The results are all yours!" Archmage Grom took care of everything.In addition, in order to thank Gretel, he also prepared an extra gift:
"I contacted the Temple of the God of War, the city guards, the parliamentary law enforcement team, and several surrounding armies. They all said that there has been no military action recently, and the occasional training injury can fully cope with the daily healing power. But!"

Before Gretel could ask, his voice suddenly increased:
"I thought of a place where blood transfusions must be needed!"

"Where?"

"Maternity! When giving birth, you will definitely lose a lot of blood! We only need to gather those pregnant women in the workhouse and those receiving relief in advance, and give them blood transfusions when they give birth, and we can verify the blood type statement Isn't that right!"

Gretel's eyes lit up.Seeing that he agreed, His Excellency the Archmage patted his chest more and more:
"If you agree, I will apply for the project now! Don't worry, the cost of supporting those pregnant women will be taken from the account of the Black Crow Swamp, and it will not cost you!"

Another update has been completed!
Ask for subscription, ask for monthly pass, ask for recommendation ticket, ask for book review, ask for various...

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