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

The low-efficiency blood-enriching magic is definitely not as effective as directly hanging salt water.

Gretel pouted.Otherwise, in the face of massive blood loss clinically, why is the first treatment not immediate blood transfusion, but immediate fluid replacement——

After all, the direct consequences of insufficient blood volume, such as palpitation and chest tightness caused by cardiac compensation, dizziness caused by insufficient blood supply to the brain, and weakened blood circulation throughout the body...

Worse than low blood cells.Hypovolemic shock, thought it was a joke?
And the blood volume has increased, and if the blood cells are 10% less, then the problem is not a big deal.Leave it alone, the human body can recover slowly.

In contrast, if the blood loss is only 10%, it is not even recommended to transfuse blood cells clinically, so as not to cause more problems.

However, no matter what the principle behind this is, it cannot change the fact that the blood-replenishing magic developed by Gretel is even less effective than infusing normal saline directly!
Faced with such an otherworldly effect, the Great Elder could only sigh in vain while being overjoyed.

After all, the future is indeed bright, and the road is indeed tortuous.A blood-replenishing magic whose effect is not as good as salt water, it is a big joke to say that it can be used on the battlefield immediately.

"Continue to study hard, and tell me what you need, and you can ask me if you don't understand." Elder Emmat patted Grete on the shoulder:

"If you need research materials, reference books and spell scrolls, need auxiliary spells, or need someone to help you split magic, you can come to me for everything you need."

"Great!" Gretel's eyes lit up:
"Can that help me develop a spell? It's... just to confirm the number of blood cells..."

He took Elder Emmat and the legends of the Magic Academy to visit his laboratory, especially the red blood cell dilution, smear, and microscope inspection devices.

Seeing under the microscope, on the 1 square millimeter grid, densely packed with 400 small square counting devices, even the experienced Elder Emmat, who is over a thousand years old, feels dizzy.

But Gretel was still looking at him eagerly:
"You see, so far, this work is particularly troublesome, and it has greatly hindered our research progress. Elder, you see..."

Can you develop a spell, raise your hand and take a picture, and you can confirm the number of blood cells in a milliliter of blood?

Lower the difficulty of this spell, and then lower it, to level 5, level 3 or even level 1, to the point where a low-level healer can easily shoot it...

I just want an automatic blood tester...

An automatic blood tester that can do routine blood tests cost 1 yuan each in my previous life. I don’t even count on routine blood tests.

The elder who saw Gretel's "help develop a small spell" for the first time, inhaled, exhaled, inhaled again, and exhaled again.

This spell may not sound too difficult at first glance, but it is extremely difficult when you think about it carefully; especially since it requires precision and requires the spell to be simple and easy to understand, it is really difficult...

But can he say he can't do it?
Ah, can he say it?

Gretel, a little guy who is less than 50 years old and has not received the orthodox magic education of the elves, has just reached the advanced elementary level, and the blood-replenishing magic has already developed a prototype;

It's rare to ask him to do a little favor, can he say it's too difficult, can't do it, doesn't he want to do it?
That definitely won't work!
Betting on the reputation of the legendary elders, and betting on the reputations of all the legendary elders in the Elf Magic Academy, he has to develop this "little spell", and it's done beautifully!

Elder Emmat readily agreed.After getting rid of the most troublesome work, Gretel once again concentrated on the follow-up research on blood-replenishing magic.

Well, a thorough study of the principle of a spell, in any case, is conducive to improving the power of the spell and reducing the difficulty of the spell.

Therefore, we still have to continue to toss the umbilical cord blood, and toss the umbilical cord blood in different ways...

"Our task is to find out which type of cells in the umbilical cord blood are most sensitive to this spell;

Then find out which type of cell is in the human body, under this spell, it can produce the most blood cells..."

"What shall we do then?"

"Take your time...centrifuge the cord blood, centrifuge, layer, take out different cells, and repeat the experiment again. Repeat over and over again, you can always find it..."

Gretel's airy "always find it out" signifies longer, harder work.

After all, the centrifuge has been buzzing for a long time, separating the cord blood into three layers, and the upper layer is a lot of plasma;
The lower layer is dark in color, full of blood cells and platelets, which cannot bear the heavy responsibility of self-differentiation;

In the thin layer of nucleated cells, most of them are white blood cells.There are still a bunch of neutrophils, lymphocytes, monocytes, eosinophils, basophils...

As for things like hematopoietic stem cells and progenitor cells that can truly differentiate, Gretel seems to have read papers in his previous life, and it seems that they only account for 0.36%±0.22% of the total number of nuclear cells or white blood cells...

It belongs to the situation where there is no flow cytometer, only relying on the buzzing of the centrifuge, with a slight slip of the hand and a slightly larger movement, these precious cells can be skimmed off to nowhere.

"Master Nordmark, what should I do..."

"Master Nordmark, no, I can't do it..."

"Master Nordmark, failed again..."

One after another, the sound of wailing resounded through the laboratory.Gretel put on a hard face and raised his voice:

"Don't make a noise! ​​Don't make a noise! ​​- first separate the upper layer, the middle layer, the lower layer, layer by layer, and try layer by layer!"

With him yelling, the elves can only be obedient and work hard.

Fortunately, these elves have a high level of spellcasting per capita, powerful spellcasting ability, and fine spellcasting control.The centrifuge buzzes once, then layers and absorbs, and you can actually do it manually:

"Water control technique! Negative pressure attraction!"

With a whoosh, the blood plasma on the upper layer of the test tube turned into a light yellow water dragon, and rushed into the next test tube.Immediately, an elf pounced on it, holding it like a treasure:
"Blood Replenishment Magic!"

"Blood Replenishment Magic!"

"Blood Replenishment Magic!"

"...Master Nordmark, it seems to have failed..."

"Well, if you fail, you will fail." Gretel nodded without any surprise.Plasma plus plasma, still plasma, nothing else.Not even cells, where to induce cell differentiation?
"Water control technique! Negative pressure attraction!"

The second time the spell was cast, a thin layer of nucleated cells was attracted out and placed separately.

The remaining thick red substance, blood cells and platelets, was rushed up again by the elves, and then injected the serum:
"Blood Replenishment Magic!"

"Blood Replenishment Magic!"

"Blood replenishing... demon... Master Nordmark, why can't it work t_t"

So much blood!
So much thick blood!

Why is so much blood poured into it, and the blood-replenishing magic doesn't respond! ——
