A Hospital in Another World?

Chapter 483: Blood Anticoagulation, Let’s Try Magic!

【Viper】 Aresol found that the messages opposing, mocking, and attacking the cowpox vaccination had suddenly disappeared.

They were no longer published in the newspapers.

The minstrels no longer sang about them.

As he was playing cards in the tavern and venting about it, someone actually retorted him!

"Who needs eight or nine hundred thousand gold coins? At most ten thousand! It’s said that the gentlemen at the hearing donated half on the spot, we only need to share five thousand!"

"Those poor who are on relief, compulsory vaccination is only right, isn’t it? It also saves us from getting infected!"

"All employees are vaccinated, and the city hall issues a certificate plaque! —I have already had all the carpet workers vaccinated. With this plaque, I can proudly shout, buy our carpets, don’t worry about getting infected!"

What happened?

How did the wind suddenly change overnight?

1. Temporary halt on mandatory vaccinations for all, shifting to mandatory vaccinations for certain key groups.

2. Abolition of the special vaccination tax, replaced by a one-time special tax for poverty relief, and the shortfall to be met through donations.

3. Price reduction, encouraging the general populace to pay for vaccinations themselves, with the city hall giving preference to those who have been vaccinated in hiring temporary employees and procuring services.

4. ...

All the previous efforts were in vain...

Mr. Viper was a bit annoyed. Luckily, he was just playing an idle game of chess; he hadn’t expected to make a killing from the cowpox incident. Let bygones be bygones, then—just look for another opportunity—

Speaking of which, where did the target go?

Garrett was still at the peak of Igor Peak. Archmage Grom had taken him to the city hall, then brought him back to the mountain top, not letting him out of sight for even a step. In fact, as long as the Thunder Tower didn’t come calling for him, they intended to keep him in the pyramid in the Black Crow Swamp and not let him leave!

Garrett settled into this situation. This mage tower, named the Tower of the Sleepless, was cold and dark, an uncomfortable place to live, but it had one advantage: abundant resources.

Since he had been left here, it would be a waste not to make use of the resources of the Tower of the Sleepless.

Garrett boldly asked the Archmage:

"What? You want human blood? —What do you need human blood for?"

"I’m developing a magic!" Garrett declared boldly:

"Transfusing blood is always such a hassle, having to cross-match every time. If there was a spell that could just be cast to figure out the blood type, that would be great!"

"Wait... first explain what a blood type is?"

"Ummm... just give me some human blood! Fresh, not much, find... four people, two milliliters each should do!"

This was nothing for Archmage Grom, even one of his students could easily procure it. What is most abundant in the Black Crow Swamp? First, corpses; second, naturally, fresh blood!

At Archmage Grom’s command, in less than ten minutes, a necromancer came holding a tray with four syringes full of fresh blood. He set it in front of Garrett, turned around, and leaned against the wall, refusing to leave.

Garrett: "..." Fine! Blood type isn’t some great mystery anyway, if you want to watch, watch. Later, during the experiment, when developing the magic, maybe I’ll even need some strong men!

He pretended not to see and didn’t speak to chase them away. A minute later, another necromancer brought in a microscope, set it up properly, and also stood still against the wall.

In the third minute, another necromancer brought the centrifuge Garrett had specified, and briskly entered.

Next, one person brought test tubes, another brought straws, another brought saline, another brought a water bath. Two others had nothing else to bring, so they came in empty-handed and shamelessly leaned against the wall.

Archmage Grom: "...... What are you all doing here?" You’re not even my disciples! Not the disciples of my disciples! Coming in and not leaving, what are you trying to do?

The two necromancers looked at each other. One, struck by inspiration, quickly answered:

"We’re here to provide the blood!"

"Yes, that’s right! We’re providing fresh blood!" His companion immediately chimed in. The others, although

silent, nodded vigorously along. The meaning was very clear:

If needed, we are also willing to provide blood!

Please let us observe!

Archmage Grom turned his head to look at the operation table. Seeing Garrett grinning and saying nothing, he didn’t feel right driving them away, so he just stared at the test tubes, pretending not to see this bunch of troublemakers.

A group of magicians watched intently, holding their breath, as Garrett labeled paper tags, stuck them on test tubes, drew blood, and placed it in the centrifuge...

Dropping serum into the test tubes, diluting the red blood cells in saline into a pale red liquid, dropping it into the serum...

Gently shaking, then using the centrifuge again, picking up each tube to observe, murmuring under his breath, quickly recording:

"Sample one and sample two, main side coagulation, secondary side coagulation... Sample one and sample three, main side coagulation, secondary side coagulation... Sample one and sample four..."

Garrett’s operations were not fast, nor very skilled, looking somewhat clumsy at times. The most precarious moment came when his hand slipped, nearly smashing a test tube.

None of the necromancers dared to help, each holding their breath, fearing they might disturb Garrett even a little.

They waited half a day until Garrett let out a wail:

"Why did they all coagulate?! —Hey, don’t you have some way to prevent this blood from clotting?"

I knew it wouldn’t work without an anticoagulant—but the problem is, I can’t make sodium citrate...

The necromancers all laughed. When it comes to manipulating blood, bones, or bodies, necromancers are second to none.

In fact, when there’s a necromancer in the team, they’re the ones tasked with preserving fresh blood.

Otherwise, how would the blood used to make inks and potions, drawn from magical beasts, be brought back?

And the teacher was watching! If the contributed method was used, the teacher would definitely reward them! Besides, someone else was experimenting, they had been very generous letting us watch, we couldn’t be stingy either!

More than a dozen necromancers all clamored to answer:

"This magic uses the least energy! A single casting can preserve one liter of third-grade or lower magical beast blood for two months without drying up!"

"This magic is third-tier, but it can preserve for six months!"

"This potion, used to preserve blood, works best for guiding magic in undead bodies!"

"This kind..."

A comparison revealed three magic spells and two potion formulas. As a result, the blood for experimentation was actually not enough; immediately, two magicians rushed out the door to get more blood.

Wherever they got it from, when they came back, a row of 50-milliliter syringes filled to the brim with dark red blood was laid out on a tray.

Garrett was startled:

"Be careful, you guys! Don’t stress people to death! A healthy adult can draw up to 400 milliliters a day, but just to be safe, 200 milliliters! After one draw, it should be six months before the next!"

"Don’t worry, no problem!" Archmage Grom hastily replied. After comforting him, he immediately glanced sideways at the students:

"Did you all hear that? Write it down quickly! —Pay attention to the limits when drawing blood, don’t kill anyone again!"

Uh... did that mean they were keeping a group of living people in the Black Crow Swamp, taking a bit of experimental material as needed?

Garrett dared not think further. He muttered to himself several times, "I’ll get results quickly, and I can save more people," and hurriedly divided the blood into small portions of five milliliters per test tube for individual tests. Archmage Grom shouted beside him:

"What are you standing around for? Go help! Can you label? Can you stick tags on tubes?"

It seemed Garrett was easygoing and wouldn’t mind everyone joining in. Just right, let the youngsters lend a hand, get to know each other,

Necromancers’ robes fluttered, a crow-like flurry, instantly crowding the experiment table.

Garrett gladly stepped back. Using the necromancers as labor, he took the boss’s position, directing:

"Don’t rush, don’t rush! Five plans, each person in charge of one, those in charge grab eight test tubes! You four, with the syringes, inject 2 milliliters of blood into each tube, make sure the names match the names on the tubes!"

"Those providing anticoagulation plans, process the fresh blood in your hands... alright, line up for the centrifuge..."

Another round of hustling followed. Centrifuging, separating serum and red blood cells, preparing red cell suspensions, cross-matching blood, and then, Garrett, looking at the test tubes in his

hand, once again issued a wail:

"This... they all clotted again! The anticoagulation isn’t strong enough!"

"This one turned into a mess! I mean, blood treated with negative energy can only be used in undead bodies, right? The cells have completely lost their vitality!"

"This... this one didn’t clot, but it all dissolved! This isn’t right either! Let me do a microscopic examination to see if all the red cells burst..."

"This... this..."

"All unusable..."

Archmage Grom was somewhat embarrassed. At the experiment table, the five magicians who provided anticoagulation plans stood in a row, each not knowing what to say—their provided solutions had already covered the most common blood preservation methods of the necromancy school. To find something else, they would have to dig through old papers, oh no, the spell library of the council...

Or...

"Go ask someone from the medical school?"

The first necromancer providing solutions involuntarily clenched his fist. Black powder trickled between his fingers. Garrett’s gaze swept by, and he suddenly jumped up:

"What is that in your hand?"

"Spellcasting materials..."

"What spellcasting materials?" Garrett crouched down, staring at the powder on the floor, almost sticking his face on it. The necromancer, looking at his black hair, subconsciously replied:

"Mosquitoes..."

"Why not use leeches?"

"What?"

"Why not use hirudins?!" Garrett’s tone became increasingly fervent. Mosquito saliva contains anticoagulants, so using mosquitoes as casting materials is fine; but using leeches, or hirudins, is clearly better!

Hirudin contained in leeches is a potent anticoagulant, often used clinically for anticoagulation and anti-thrombosis!

"Try again! Please, try with leeches again!" Garrett grabbed the test tubes, swiftly prepared the samples. A row of four, each with two milliliters, filled them up, pushed them forward full of hope:

"Please, let’s do this again!"

Just not sure if using hirudin for anticoagulation might overdo it, ending up unable to clot at all...

If it really doesn’t work, maybe they’ll have to bring a blood clan member over to see if he can taste the different blood types...
