Garrett was ceaselessly bustling among the necromancers, gesticulating and issuing commands:

"Keep the serum on top! Extend the red blood cells to the bottom! Don’t suck the serum above into it!"

"Don’t skimp on the straws! Change them after using! Change one!"

"First angle the straw into the test tube, then straighten it, dip it deep into the tube! Don’t touch the tube walls! It’s all wasted!"

"Keep the water bath temperature at 37 degrees, the same as body temperature, but this is the blood of the dead, so 37 degrees might not be correct. Thus, get a few more water baths, adjust several temperatures!"

It must be admitted that the hands-on ability of magicians has surpassed that of college students in the past world, and even those who have tinkered in a lab for a year as master’s students. Among magicians, necromancers are particularly skilled—

The consensus in the field is that only those mages in the alchemy branch of the transmutation school can compete with them in operational skills.

Even so, Garrett had many areas to personally supervise. Details are the devil, even a simple cross-matching blood test has seven or eight, maybe even a dozen details to pay attention to.

Almost there, he could have missed it, maybe the results would be wrong...

Garrett was stepping from one foot to the other, and finally, after the necromancers finished centrifugation, dilution, and had added red cell suspension to the serum, he couldn’t wait to jump in and grab a syringe:

"Give it to me! Give it to me! While the mixture needs to incubate in the water bath, give me one first, let me take a look under the microscope!"

Ah, the blood was even darker than venous blood! Dark red, blackish red, the color, caught up with a blood clot! Drawn directly from the corpse’s blood vessels! Still flowing!

Woo woo woo, he must personally see what the red blood cells look like under the microscope!

Garrett held his breath, dripped blood, pushed the slide, and stained. Adjusted the objective lens, adjusted the eyepiece...

Couldn’t see clearly.

Er, the dye that can stain living red blood cells, couldn’t stain the dead blood drawn from the corpse...

Garrett hung his head in frustration, secretly deciding to check the papers after today’s experiments to see if there were any experimental methods for observing the morphology of red blood cells in corpses. To his right, a bottle of liquid was already handed over:

"Do you need dye? Or should we help you dye it? There’s a knack to dyeing the blood of non-living creatures, it’s not just about dropping the dye—"

Seeing Garrett’s somewhat surprised look, the necromancer smiled:

"Strange, isn’t it? You’ve been using the microscope for so long, seen so many bacteria for so long, of course, we also use it to look around! It’s just that staining is more troublesome. If you had come a month later, the paper would have been published!"

Since the paper was already written, Garrett didn’t bother with drawing, just took a look to satisfy his curiosity. Hmm, many of the red blood cells still had shapes, hadn’t burst. Perhaps the cross-matching blood test could work...

After this series of operations, once the mixture had incubated long enough in the water bath, results began to emerge one after another:

"This group won’t work! All clotted!"

"This group too!"

"This group didn’t work either! None clotted!"

"This group..."

About ten necromancers, each trying three different methods, all failed. They didn’t look discouraged at all, quickly discussing and immediately starting a new round of experiments:

"Forget the anticoagulation spells! After all, this blood, it’s all been processed!"

"Adjust the temperature again! Adjust several more groups, down to freezing!"

"Increase the proportion of negative energy!"

"Split half the people off to work with fresh blood! First, get 100 people to draw blood, compare, and see how many blood types there are!"

As the experiment progressed to this step, Garrett simply handed over the leadership, sitting aside, watching the necromancers work. After two days of tinkering, the side using fresh blood first came through with cheers:

"We did it! We did it!"

"There are four types! Four different types of blood, each either clots with the others or one tube will clot! The same blood type, both tubes don’t clot!"

"Time to write a paper!"

"Publish a big one! This time we must publish a big one!"

"This time I’ll at least get second authorship!—Research points! Contribution points! Rewards within the school!"

"Finally can level up to a three-ring arcane mage!"

"Let’s try a transf

usion!—No, Mr. Nordmark doesn’t allow transfusions, then just mix a large amount of the same blood type, see if it clots!"

Garrett leaned against the lab bench, watching the necromancers cheering and couldn’t help but smile.

Even if a bit thinner, skin a bit waxier, demeanor a bit gloomier, necromancers are still human, not skeletons. When they get excited, they’re truly infectious. Plus, necromancers celebrate with double the excitement, double the joy—

Living people were responsible for shouting and cheering, running around with test tubes. Skeletons were responsible for waving their arms, jumping and flipping, doing handstands, taking off their own heads, tossing them back and forth...

Aside from being unable to make noise, they made for an excellent atmosphere team, tireless, not crying out when they fell, perfectly filling in for the necromancers’ lack of physical prowess.

Garrett watched happily for a while, then returned his attention to the blood in front of him. This previous round of work was all preparation; his real goal was to develop a blood-testing magic.

100 samples, each one milliliter, all had been labeled by number. Someone had already sorted them into four piles according to blood type. Garrett casually grabbed a test tube, drew a drop of fresh blood, and cast 【Determine Lineage】—

Since his return to Thunder Horn, he had searched through the archives and found an advanced version. This casting, the magical feedback provided more information than the original version:

The blood belonged to a human, male. Strength level, ordinary.

That was it.

That was it...

Strange. Why could it identify the species but not the blood type?

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

During his trip to the Dwarf Kingdom, Garrett had based on 【Determine Lineage】 developed a blood oxygen monitoring magic, gaining some experience in dissecting this magic. Now, it was easy going.

Back then, he had discovered that removing the feedback unit from this magic would yield many miscellaneous messages. And the feedback unit, in a sense, was combing through these messages, extracting a fixed few, interpreting them for the caster:

For example, species: human, elf, orc, dwarf, half-breed, Garrett read from the spell data that it could even distinguish some magical beasts, even dragons;

Gender: male, female (other species might have different genders);

Strength level: commoner, then from level one to over ten levels, seemed all decipherable;

Amazingly, this spell could even roughly distinguish whether one was a fighter or a caster...

There must be more chaotic information it couldn’t interpret, buried in the feedback!

And among these messages, maybe one was about blood type?

Meaning, I just need to find among all the information, the same spot that’s exactly the same for one blood type, different for four types. Ideally, it would be in the same position in the stream of information—

So, all the work starts with recording information!

Garrett clenched his fist, cheered himself on, and started drawing.

100 blood samples meant 100 pieces of chaotic information, needing to be recorded as accurately as possible. The more accurate the record, the easier the comparison, the greater the chance of finding what he wanted.

Go for it, Garrett!

He immersed himself wholeheartedly. The 【Endless Ink Pen】 fluttered up and down, leaving chaotic ink spots, circles, arcs, and various stripes on the paper. Large and small, thick and thin, like a child’s scribblings.

But of course, no one dared to underestimate these smudges. Observing necromancers saw him writing and drawing, even deliberately taking a roundabout way to avoid that side, not even the skeletons went there.

Garrett buried himself in recording, not knowing the time, until he finally heard someone shouting nearby:

"Master Nordmark!"

"Master Nordmark!"

"Garrett!"

Garrett jolted, coming back to reality. Beside him, seemingly even drier than before, Master Grom, his dry, yellow face tinged with a layer of red, said excitedly:

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

"…Oh."

Garrett blinked, showing a smile that met the archmage’s expectations.

So?

So?

What does it matter if this corpse, dead for ten or eight years, still had flowing blood, and its blood type was determined?

I’m a doctor! I don’t want to become a forensic scientist!

"After determining the blood type, they transfused the corpses with matching blood, and the blood didn’t clot! And indeed, the vitality of the corpses increased!"

Master Grom was excited beyond measure. Preserving corpses, maintaining corpse vitality, has always been a focal difficulty for the school of necromancy. Previously, everyone had tried transfusing living human

blood into corpses, and most of it clotted, but now, Garrett’s discovery had solved this problem!

"Don’t worry, this paper will be published under your name, you decide who gets second authorship! The results are all yours!" Master Grom took it all upon himself. Besides, to thank Garrett, he had also prepared an additional gesture:

"I’ve contacted the Temple of the War God, the city guards, the council’s enforcement team, and several nearby military units. They all said, there hasn’t been any military action recently, occasional training injuries, everyday healing power can handle it. But!"

Without waiting for Garrett to inquire, he suddenly raised his voice:

"I thought of a place that will definitely need transfusions!"

"Where?"

"Women in labor!—During childbirth, they will definitely lose a lot of blood! We just need to bring those from the charity hospital and those receiving relief who are pregnant together in advance, and give them transfusions during childbirth to verify if the blood type theory is correct!"

Garrett’s eyes lit up. Seeing his agreement, the archmage thumped his chest even more resolutely:

"If you agree, I’ll apply for the project right now! Rest assured, the cost of supporting those pregnant women will come from the Black Crow Swamp account, it won’t spend your funds!"
