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

Use red blood cells as a substrate to generate blood, no?

That must not work.

Gretel looked back at the two red, swollen, almost tearful faces, and sighed silently.No way, I had to knock on their desk:
"Change to a high-power microscope! Change to a high-power microscope! - Take a closer look at the cells in the blood and see what they look like! Mark the cell membrane, cytoplasm, and nucleus for me!"

Two hapless elves whimpered to try.After drawing blood cells, diluting them, making smears, and tossing about under the microscope for a long time, he came over dejectedly and reported:
"Can't see the nucleus..."

It must be invisible.Whether red blood cells or platelets, don’t they have nuclei?

Without a nucleus, what can be used to replicate itself?Take your feet?
After explaining the "steps of cell replication" to the elves, Gretel held his cheeks and looked at the last thin layer of nucleated cells.

What to do, 0.36%, up to 0.58% of stem cells, it feels like it can't be made out... Otherwise, the can will be broken?

"Inject the test tube!"

"In vitro test!"

"It's red! It's red!" the elf who took over the experiment exclaimed excitedly.Gretel nodded calmly:
"Repeat the experiment!"

"Repeat twice!"

"repeat three times!"

--very good.

very good.

Nice job.

After adding the nucleated cells isolated from the umbilical cord blood to the serum in the test tube, the effect of the blood-enriching magic can be said to be immediate.

The red color in the test tube rose almost immediately.

From the place where the nucleated cells are dripped, it diffuses to the entire test tube, showing that the hematopoietic stem cells inside are self-replicating and proliferating in large numbers, increasing by 10 times, 100 times, 1000 times, 10000 times...

It grows exponentially, and finally, enough blood cells are formed to be replenished into the blood in large quantities.

"Everyone repeat three times!" Gretel raised a big smiling face, high-spirited:
"Each person receives three umbilical cord blood, puts it in the centrifuge, releases the blood-enriching magic for each part, and observes its effect! Now, start!"

The elves file in and file out again.Soon, the humming sound of the centrifuge spinning filled the entire room.

After another short while, "Huh", "Ah", "Oh", all kinds of voices expressing surprise or sudden realization, sounded one after another in front of each experimental platform and each microscope.

"You remember it!" After inspecting each experimental platform and reading each experimental report, Gretel jumped onto the podium and concluded his speech:

"—Not all parts of the umbilical cord blood respond to the blood-enriching magic! Only a small part of the umbilical cord blood, the part of the nucleated cells, or even a small part of the nucleated cells, can respond!

Now, the experiment continues!Use mental power to lock the whole blood of the umbilical cord blood, focus on the part of the nucleated cells, and try to release the magic of replenishing blood again! "

It turns out that an understanding of spells does help with spell power—or whatever.

After this round of experiments and intuitive spell observation, although the spell output of the elves has not changed, the effect of spells has risen to a higher level——

It can be seen from the visual effect that the red color in the serum test tube quickly diffused, much thicker than when the spell was cast before;

It can be seen from the microscopic examination that the number of red blood cells under the microscope has also increased compared to before...

"More than ten times!"

"At least ten times more!"

From Cusa Oak to Elder Fahim, everyone looked at Gretel in the wrong way.Just adjusting the cognition, the power of the blood-enriching magic has increased by more than ten times...

If only other spells had such a good thing!
If the other attack spells of the elves can be increased by 10 times in a flash, why worry about the enemies on the other side of the big rift!

There is no need for everyone to think hard and fight so hard!

Gretel was not satisfied.Ten times, what is ten times?
In the case of blood loss of 400 ml, 800 ml, or even more, is it enough to replenish the blood at one time?
Can it take into account the functions of capacity expansion and rehydration?

Can it be adaptive according to the amount of blood loss of the subject?
For high-level fighters, can stronger... um, maybe stronger blood be produced to supply their fighting needs?

Gretel knew nothing.Everything requires him to keep experimenting and improving.

At the very least, using umbilical cord blood alone is not enough.I have to find another way to work directly on the subject...

"Record the characteristics of spell fluctuations!"

"Record, where does the blood-enriching magic arouse the greatest reaction on the subject!"

Gretel just gave orders—in fact, he didn't quite know whether there was such a detection circle, how accurate it was, and whether it could perfectly cover the entire body of the subject.

However, it is clear that the elves have accumulated a lot in this area. With Gretel's order, the elves set up a detection circle to cover the whole body of the rabbit:
"Cast!"

"—cast a spell!"

Above the detection circle, a phantom of a rabbit rises quietly.The fine and dense magic lights and shadows outline the outline of the rabbit, bones, internal organs, blood vessels, and each detail is detailed and subtle.

As soon as the blood-enriching magic fell, the phantom of the rabbit appeared brightly and darkly, flickering indefinitely.Gretel couldn't help walking a few steps quickly, staring at the phantom:

On the phantom, some places are bright, and some places are dark.In general, with the heart as the center, a large and fine net is unfolded, and every part of the veins, arteries, and blood flow is lit up.

But the blood vessels aren't the brightest yet.the brightest part...

"strangeness."

"strangeness."

"It's not a blood vessel!"

"Why, the blood-enriching magic, the part of the body that responds the most, isn't the blood vessel?"

"Can't blood replicate itself?"

"Wait, this lighted area is—"

Around a magic circle, a full ten elves gathered, head to head, pointy ears to pointy ears, more crowded than the morning rush hour subway.

But no matter how crowded they were, everyone made room for Gretel to look directly at the magic circle with his hands behind his back, and ordered softly:
"Record. The part of the blood-replenishing magic that triggers the magic reaction is mainly concentrated in the spleen and——the bones!
The long bones of the limbs, including the humerus, femur, and iliac bone! "

When he spoke, his eyes were shining brightly, and his hands were behind his back, holding each other firmly.On the left and right, two elves stood beside him, recording without raising their heads:
"Forget about the spleen, it's too fragile, and it's easy to bleed when you touch it. Bones...bones...

Take the bone and puncture the needle, puncture to get the bone marrow, put it into a serum test tube, and release the blood-enriching magic to test it! "

"What...you're going to pierce the bone again..."

More screams, wailing, one after another.

In December 2022, the monthly tickets will be closed, with 12 monthly tickets.

There are many words of gratitude that I want to say, but I am exhausted physically and mentally, so I can only say thank you in unison.

According to the agreement, in January, I owed everyone 1 monthly tickets plus changes, plus the 14 tipping plus changes owed, a total of 27 plus changes were owed.

I made a form and memorized everything one by one.

I am exhausted physically and mentally recently, please allow me a little more time.

Thank you.

Thank you.

In 2023, I wish you and your family good health, peace and joy, and all the best.

You have to be fine.

You must be well.

The author joins Little Gretel in wishing everyone well.
