"..." I approach Sakura completely, the scent of blood in the room is now relatively strong and Sakura seems mortified to realize that she is next, Sakura's gaze goes to Yuki and Kaori with their horrible torture.

She seems to be imagining what will happen to her, since the torture is continuous on them even though I'm not doing anything anymore.

'Let's see what to do...' I stare at Sakura, she is quite narcissistic and I want to use that against her, but that would boil down to psychological torture.

"Yes...this is probably a good option" I use [Essence of Creation] creating an extremely thick and resistant glass barrier, keeping her trapped inside with me inside, we can see our reflections in the glass perfectly like mirrors, which is great for her to see what's going to happen to her.

"There, much better like this, isn't it? Isolated from the outside, we can start some really interesting experiments." I generate a table with various needles, each needle has different doses of my mana with small doses of my blood.

"You know, I've always been curious, what happens if I inject my mana directly into someone's body with my blood? Each one is quite different." Tsukuyomi got pregnant with my mana.

While my blood is something "alive" that literally attacks and devours things that are not me, so having my blood injected into someone's body would be death for most, and only strong people can drink my blood or have it injected into their body.

What limits this to Delphina and Grimm and a few others, of course if I want to, I can make the blood not attack, while my blood also doesn't attack Zephyra because we are deeply connected.

"Let's start with a 10% dose." I deduce that Sakura's body will be deformed, the mixture of my mana and blood together with the fact that she cannot die will horribly deform her body.

Which is perfect, she is someone who cares too much about her own beauty, so having her body deformed will be physically and psychologically painful.

"This is strangely fun, it's like a guessing game, how will your body deform? And how many syringes will you be able to handle? I have one there that's 1200% with a concentrated dose of blood." I say excitedly, grabbing the needle firmly and approaching her arm.

She cries, drooling on the gag while shaking her head negatively, trying to get out of the restraints, the needle slowly enters her arm and I press, injecting the liquid mana with blood into her body.

"...There...the 10% has been injected." I step back and observe, her arm gets prominent veins as if they're going to burst.

"My blood is quite violent, isn't it?" I say playfully, watching the blood with the liquid mana spread, it takes 5 minutes for all the veins in her body to become prominent.

Her eyes bulge as if they're going to pop out of her head while blood drips from her eyes, nose, ears and mouth.

"Is that all? Well, it seems that 10% is too little...great, let's jump to 50%" I grab another syringe, approaching her again and touching the tip of the needle to her vein, then I pierce and inject the liquid.

As soon as I do this, she struggles violently in the restraints, convulsing while her veins turn black and the bleeding increases, I step back, waiting for it to spread.

Every time I give her is 5 minutes again, and unfortunately nothing else happens.

"Hmm, I guess it makes sense." My mana is extremely chaotic and my blood is very violent, but even though it is, my blood is more destructive like a virus that destroys the cells.

And my mana is chaotic, contracting and retracting, destroying everything in its path, the combination of the two really deforms the body, but less intensely than I thought.

"Well, this seems painful, but it's still not as I want it...let's jump to 120%." I grab another syringe, the liquid in this one is completely black, losing the red appearance of the others.

"Hmm! HMMFF! HMFFFFMM!!" She struggles, groaning for me not to do it, but I ignore it, injecting another one into her vein, I take a few steps back and watch.

And finally the body manages to show an interesting reaction, her arm begins to swell as if it's going to burst, while reddish blood blisters form.

But it stops there, her body swelled slightly and red blisters appeared, but that's it.

"It seems the immortality that this universe provides is trying to heal you." I say, grabbing another syringe.

"300%." I say the percentage, injecting this syringe into her, the process is much faster, her veins burst, spreading blood all over the room, which also gets me dirty.

Her arms swell even more while various blisters appear all over her body and her face, making her look very ugly.

"Hmm...it's quite different from what I expected, but it makes sense, well, that's what experiments are for, and you look hilarious with your face full of blisters hahaha." I expected her body to deform violently.

However, it is just destroying itself from the inside, of course it is deforming, but not in the way I expected it to be.

'Well, it's not like I'm radioactive, I can't expect her body to start generating mutations out of nowhere, I think if I keep injecting, she'll just destroy herself even more...' I'm curious about how much her body can withstand.

"Well, let's skip the 500, 700, and 900 doses, I'm going to give you the 1000%." I grab the syringe that has a 100% black liquid inside, I go to her and inject it, ignoring her ugly crying.

"..." I take several steps back to avoid getting even more dirty with her blood and observe.

The effect is much more obvious, holes begin to appear in her body along with a lot of blood leaking from the holes, the holes appear and grow rapidly, making her body have so many holes that it looks like a piece of cheese.

'So this is what happens when my blood is flowing in large quantities through the body of other beings.' Using magic, I can see the microscopic world, my blood is literally devouring her body from the inside like an invasive parasite.

But the pace is absurdly fast, faster than any bacteria or virus, a virus takes on average minutes to hours to bind to a cell in order to replicate, but my blood is literally devouring the cells in seconds, replacing them completely while seeking new cells to devour.

'My body is really bizarre.' It's strange to know that this thing runs through my veins, I've never deeply analyzed the behavior of my blood.

"Well, 1000% ended up ruining your body a bit." I look at her face, it's quite deformed with holes that allow me to see the inside of her body.

Along with the blood that flows, a black and viscous gum has also started to ooze from the wounds.

"If this were the outside world, you'd be dead, you should be grateful to me for still being alive, don't you agree?" I grab another syringe.

"I was eager for the 1200%, but seeing that the effect of the 1000% wasn't as expected, I'll skip...well, how about we test the 5000% one?"

"This one has a concentration of almost 1 liter of my blood, enough for...who knows? I don't know what 1 liter of my blood would do to the body of another being, so let's test it now and find out together." The syringe has 30 ml of a black liquid, it's a concentration of liquid mana and blood.

Sakura doesn't even have the strength to struggle anymore, she just makes strange and unintelligible grunts that I don't understand anything, but it's probably a request to stop or something like that.

"3...2...1...and here we go." I apply the syringe directly to her throat this time, the liquid being slowly injected into her, as soon as it's done, I step back and start observing.

Soon I start to hear a strange sound, it's like a crackle or bizarre micro-clicks coming from Sakura's body, quickly holes begin to appear and grow massively on Sakura's body, forming cavities and tunnels so large that they are visible.

The structures of her body begin to collapse, deteriorating so quickly that the breakage is visible, her fingers and arms begin to fall to the floor and even on the floor they dissolve into a black mass with a strange smell that is not exactly blood.

The holes are so large that I can see inside her body and even through to the other side, through the glass I see that her back is completely open, allowing me to see her lungs moving and her bones fragmenting.

Several of her organs are literally hollow with nothing inside, but it doesn't stop, every second the holes grow while flesh and black mass fall to the floor, forming a viscous pool.

"Hahahahaha I can hear it!!" I laugh at this absurdity, they are cells, and yet I can hear them devouring everything, it means that the speed, quantity and volume at which they are acting is at an extreme level.

It's like bacteria, you normally can't see bacteria, but when they accumulate in mass, you can see them, even though they are microscopic, in this case, instead of seeing, I can hear the cells being devoured by my blood.

"Sakura, you're really interesting now, you look like those chaotic works of art." I say, seeing that all that is trapped in the restraints is an arm that is almost falling and her head.

The rest of her body crumbled to the floor, falling into that black pool, I give a satisfied smile, knowing that the pain of this is hell, I think in fact this is even worse than the fire torture from Hana and the cannibalism torture that Yuki and Kaori are doing now.

"Well, thank you for your help, it's very useful to know how powerful my blood is." Grimm had already told me that I don't truly know the full power of blood magic.

And now knowing that my blood is so dangerous, imagine if I learned to use blood magic and started using my blood in combat! It would be incredible, even though in this case I have also used liquid mana, the effect is still entirely due to my blood.

The liquid mana in the syringe served only to compact the blood and keep it alive and stable outside my body.

"Well, I think it's going to take a long time for you to regenerate, since this damage is too high even for the standards of the wounds I'm causing the others, so I'll stop here for now."

"We can test other percentages later!" I open the glass box, getting out and closing it again, it's obvious that I'll make her suffer a lot more.

I think I'll keep them all here in these specific tortures for 2 months before allowing them to act as students in my school.

"Well, well, well, now it's just you two, Kaito and Tsubasa, you must have been really anxious for your turn?" I look at them excitedly about what's to come, with each new torture, those who haven't been tortured become even more desperate.
