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

Chapter 487 Blood anticoagulation, try magic! (Bugfield leader plus update 5)

【Pit Viper】Arezzo found that the news of opposition, ridicule, and attack on vaccinia vaccination suddenly disappeared.

No longer published in the tabloids.

The bards no longer sing.

When he was playing cards in the tavern and complaining to others, someone actually refuted him!
"Where do you want 900,000 gold coins? At most [-]! It is said that the gentlemen at the hearing donated half of it on the spot. If we need to share, the maximum is [-]!"

"Isn't it right for those poor people who are on relief to be vaccinated? It will also save us from infecting us!"

"For families where all employees are vaccinated, the city hall will issue a certificate card! - I have asked all the carpet weavers to vaccinate. With this brand, I can shout loudly, buy my blankets, and don't have to worry about being infected!"

what happened?
Why did the wind direction suddenly change overnight?

Mr. Arezzo asked and asked and asked again, and at last he found out what was going on.It turned out that after the city hall secretly released rumors, the nobles and wealthy businessmen who did not want to pay taxes created public opinion, and the final hearing was communicated, a satisfactory compromise was reached among the various forces:
1. For the time being, the mandatory vaccination of the whole people will not be promoted, and it will be changed to compulsory vaccination for some key groups;
2. Cancel the special tax for vaccination and change it to a one-time special tax for the poor, and seek donations for the insufficient part;
3. Reduce the price and encourage the general population to vaccinate at their own expense. The city hall will favor those who have been vaccinated in terms of hiring temporary employees and purchasing services;

4,……

The previous hands and feet were in vain...

Mr. Viper was a little annoyed.Fortunately, he was just playing casual chess, and he didn't expect to succeed with a single blow from the cowpox incident.If the matter is over, let it be over, and looking for another chance is——

By the way, where did the target go?
Gretel is still on the summit of Igor Peak.Archmage Graham took him to the town hall and back to the top of the hill, never letting him out of sight.Even, as long as there is no important person from the Thunder Tower, this will make him stay in the pyramid in the Black Crow Swamp, don't even think about leaving!
Gretel would settle down as soon as he came.This mage tower, named the Tower of Sleepless, is cold, dark, and uncomfortable to live in anywhere. There is only one advantage: rich in resources.

Since I was left behind, I would feel sorry for myself if I didn't use the resources of the Tower of Sleepless to do something.

Gretel was confident, and reached out to the Archmage:

"What? Human blood?—what do you want human blood for?"

"I want to develop a magic!" Gretel said confidently:

"It's too troublesome to cross-match blood every time for blood transfusion! If there is a spell, you can cast it and find out what blood type it is!"

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

"Emmm... you give me human blood first! I want fresh ones, not too much, just find... four people, two milliliters each will do!"

For this matter, not to mention Archmage Graeme, any of his students can be found with a wave of his hand.What is the most popular in Black Rook Marsh?One is a corpse, and the second is naturally blood!
The archmage gave an order, and within 10 minutes, a necromancer came over with a tray of blood and four syringes of blood.Put it in front of Gretel, turn around, lean against the wall, and stand still.

Gretel: "..." All right!Anyway, blood type is not a great mystery, you can read it if you want.When doing experiments later and developing magic, maybe we will have to pull strong men!
He pretended he didn't see it, and didn't open his mouth to drive people away. After 1 minutes, the second necromancer came in with a microscope, placed it properly, and stood against the wall as before.

In the 3rd minute, another necromancer walked in quickly, holding the centrifuge Gretel wanted.

Next, one person will deliver the test tube, one will deliver the straw, one will deliver the saline solution, and the other will deliver the water bath.There were two other people who really had nothing to give, they came in empty-handed, and stood cheekily against the wall.

Archmage Grom: "...what are you doing here?" You are not even my disciples!Not my disciple's disciple!What do you want to do if you sneak in and don't leave?
The two necromancers looked at each other.One of them had an idea and quickly replied:

"We're here to provide blood!"

"Yes, that's right! We provide fresh blood!" His companion immediately followed.Although the others didn't speak, they also nodded their heads up and down.That meaning is very clear:

We are also willing to donate blood if necessary!
Please let us watch!

Archmage Grom turned his head to look at the console.Seeing that Gretel was smiling and remained silent, and it was not easy to drive people away for him, he could only stare at the test tube, pretending not to see this group of worried people.

A group of magicians held their breath, watching Gretchen write up the paper, sticking the test tube, taking the blood, and centrifuging it in the centrifuge...

Take the serum and drop it into a test tube, take the red blood under the serum, make a light red liquid in normal saline, and drop it into the serum...

Shake it slightly, put it on the centrifuge again, pick it up one by one to observe, chant words, and quickly record:
"Blood sample No. [-] and blood sample No. [-], primary side coagulation, secondary side coagulation... No. [-] blood sample and No. [-] blood sample, primary side coagulation, secondary side coagulation... No. [-] blood sample and No. [-] blood sample..."

Gretel's operation is not fast, or even not very skilled, and he seems to be in a hurry in some places.The most thrilling time, my hand slipped and almost smashed the test tube.

None of the necromancers dared to go up to help, and all of them held their breath, for fear of disturbing Gretel in the slightest.

Wait for a long time, until Gretel uttered a whine:
"Why is it all coagulated! —Hey, do you have any way to prevent this blood from coagulating?"

I knew it wouldn't work without anticoagulants—but the problem is, he can't make sodium citrate...

The necromancers all laughed.When it comes to playing with blood, playing with bones, and playing with corpses, necromancers take the second place, and no school dares to take the first place.

In fact, when there is a necromancer in the team, fresh blood needs to be preserved, and the necromancer is always the one to do it.

Otherwise, how did the monster blood used to make ink and potions come back?

And the teacher is watching!If the methods contributed can be used, the teacher will definitely give compensation!Besides, others have been generous enough to let us see the experiment, so we can't be stingy!

A dozen or so necromancers rushed to answer:

"This magic consumes the least amount of magic! One cast can save the blood of monsters below level three, and it won't dry up for two months!"

"This magic is of the third level, but it can be preserved for six months!"

"The blood preserved by this potion is used to guide the magic power in the body of the undead, and the effect is the best!"

"This kind of..."

Under the cross-comparison, three kinds of magic and two potion formulas appeared in one breath.As a result, the blood used for the experiment was not enough, and two magicians rushed out of the door immediately to get the blood.

I don't know where I got it, but when I came back, there was a row of 50ml syringes on the plate, full of dark red blood.

Gretel looked startled:
"Be careful! Don't smoke people to death! A healthy adult can smoke up to 400ml a day, 200ml to be on the safe side! After smoking once, the next time you smoke will be six months later!"

"Don't worry, no problem!" Archmage Grom rushed to answer.After the comfort here, the other side immediately gave the students a look:
"Have you heard it all? Hurry up and write it down! - Pay attention to the limit when drawing blood in the future, don't kill people anymore!"

Uh... This tone, does it mean that there are a group of living people in the Black Crow Swamp, and if they need experimental materials, they just get some?

Gretel didn't dare to think about it any further.He silently recited "I will get the result sooner, and save a few more people" several times, and quickly divided the blood into small portions of [-]ml test tubes for each test.Archmage Grom shouted from the side:
"What are you doing in a daze? Go up and help! Can you write a paper sign? Can you stick a test tube?"

It seems that Grete has a good temperament, and he doesn't mind if everyone skips class.Well, it's just right, let the boys make a start and get familiar with each other,
The black robes of the necromancers fluttered, and crows filled the experimental platform in an instant.

Gretel took a step back happily.Treat the necromancers as labor force, stand in the position of the boss, pointing fingers:
"Don't worry, don't worry! There are 5 plans, each person is responsible for the same, and the person in charge takes 8 test tubes! Four of you, hold a syringe, inject 2 ml of blood into each test tube, pay attention to the name and the name on the test tube Be unanimous!"

"Those who provide the anticoagulation solution, deal with the blood in your hands...well, line up and go to the centrifuge..."

Another toss.After centrifuging, separating serum and red blood cells, making red blood cell suspension, and cross-matching blood, Gretel looked at the test tube in his hand and wailed again:
"This... this is still all coagulated! The anti-coagulation is not strong enough!"

"This is a mess! I said, the blood treated with negative energy can only be used on undead creatures, the cells have lost their vitality at all!"

"This... this is not coagulated, but it is completely hemolyzed! This is wrong! Let me check under the microscope to see if the red blood cells are all broken..."

"This one……"

"None of them can be used..."

Archmage Grom was a little embarrassed.Beside the test bench, five magicians who provided anticoagulation solutions stood in a row, and none of them knew what to say—the solutions they provided had already covered the most common blood preservation methods in the Necromantic system, and they wanted to find other methods. , I’m going to the pile of old papers, oh no, the council’s spell library has been turned over...

or……

"Ask someone from the medical department?"

The necromancer who was the first to offer the plan couldn't help but clenched his palms tightly.Between the fingers, the black powder rustled down.Gretel glanced, and suddenly jumped up:

"What is this in your hand?"

"Materials for casting..."

"What spell-casting material?" Gretel squatted down, staring at the powder on the ground, almost sticking his face on it.The necromancer stared at his black hair, subconsciously replied:

"Mosquito……"

"Why not use leeches?"

"what?"

"Why not use leeches?!" Gretel's tone became more and more fanatical.Mosquito saliva contains anticoagulant substances, so there is nothing wrong with using mosquitoes as spell-casting materials; however, it is obviously better to use leeches, or leeches!
The hirudin contained in leeches is a powerful anticoagulant, which is often used clinically for anticoagulant and antithrombotic!

"Try again! Please, try again with leeches!" Gretel grabbed the test tube and started to take samples quickly.Four tubes in a row, each with [-] milliliters, after filling, push them in front of each other with hope:
"Please, let's do it again!"

I just don’t know if using hirudin to anticoagulate, will it be too strong, and it will not coagulate in the end...

If it really doesn't work, you can only find a blood race to see if he can taste different blood types...
