Muscles grow stronger the more they are used.
They tear, relax, suffer damage, and as they recover, they grow stronger.
If they are overstimulated, they tear to the point where they can no longer be used, but if they are pushed just beyond their limits, they grow.
The same applies to a man’s “mana stick.” This technique was discovered by Hydra, the Duke of the Earth.
“It’s simple. You just need to infuse mana into the mana stick.”
I began a lecture for the special class in the old school building.
“This is what we call the [Kegel Method].”
In reality, it’s called ‘kegel exercise’.
“By continuously circulating mana through the mana stick, the mana seeps into every part of it, expanding the mana stick from within. Rather than pulling it outward by force, you keep pushing mana inside, making it grow from within.”
This is one of the mana tempering techniques humanity lost when demons were exiled to the Demon World.
“By continuously injecting and stimulating mana, you increase the space that mana can occupy. And when that space is created, the human body expands to fill the void.”
This technique was lost to humanity when demons were exiled, leaving them to live without it.
“We talked about side effects, right? Yes, this method does cause growth. Once the skin or leather expands, just like stretched skin, it can’t return to its original size.”
A long time ago, when demons still lived among humans…
– Hey, do you know how much praise I received from men? [The Great One] Hydra, or [The Big One] Hydra. Humans should be angry because all males were once capable of growing to match the exact size of their female partners, and now that tempering technique is lost.
Even those born small could grow if they had Hydra’s mana tempering technique.
“As the theory of non-attribute mana spread, not only did faculty members secretly begin to train, but academy students who overheard the theory also started practicing non-attribute mana in secret. The same principle applies here. Anyone can do it if they know how.”
It was a different world.
“I didn’t develop this technique. I found it while adventuring through some demonic lands, in a dungeon-like place.”
“A dungeon… with such a technique…?”
“It was fascinating. I wondered why they sealed something like this. Perhaps some force didn’t want this knowledge to spread.”
Maybe the Goddess and Angels?
That world was destroyed when the Goddess exiled Hydra, Changyeom, and other demons to Hell.
The Kegel Method doesn’t actually exist in this world, but I brought plausible excuses from Hell to back my claims.
“Perhaps this mana tempering method was declared ‘heresy,’ and as a result, no one could use the Kegel Method. Those who could were either killed or unable to leave any records.”
“That is….”
“But someone sealed it, and I discovered it. That’s how it happened.”
There might have been an Angel who benefitted from Hydra’s method even as the demons were exiled.
Hydra may have aided some angels, like Futariel, who did not fully transform into a feminine form.
“Perhaps the reason for the seal was its limitless potential.”
The class listened attentively.
“Then, Dr. Phoenix, what are some practical uses of this method?”
“Um, I’m not a doctor, Professor Kadisha.”
“Oh, sorry! I got carried away. It feels like I’m at a symposium for academic research, haha.”
Though not alchemy or magical engineering, this new theory about mana biology made Professor Kadisha look at me as though I were presenting a groundbreaking thesis.
“Um, excuse me. So, was it this tempering method that made you… well, grow?”
Yunia pointed at my lower body.
“Did Student Phoenix… grow this way using the method?”
Though my pants concealed it, Yunia had some idea about my size.
“No, I’m just naturally big.”
“Oh, I see!”
The tempering method was Hydra’s mercy for the so-called “small ones”.
“The Kegel Method is like inflating bread with air. When you slice bread, you see air pockets between the layers.”
Those born large didn’t need the tempering method because they naturally grew large.
“But you can still grow bigger using the mana tempering technique.”
“…Bigger than that?”
“Yes.”
Yunia’s eyes widened in disbelief.
Though sensitive, Yunia didn’t raise any objections to the Kegel Method.
Why?
“Because theoretically, it’s possible to use mana to temporarily enlarge specific body parts… it’s not impossible.”
The theory was already proven, and Yunia could verify it based on her instincts.
“But wouldn’t that turn it into something soft?”
“What?”
“No, I mean, in the bread analogy. If too much air goes inside, doesn’t the bread become too soft when you touch it?”
“Exactly. That’s why the Kegel Method is a ‘continuous magic’ technique to solve that issue.”
I reached out to Yunia.
“Want to try holding my middle finger?”
“My middle finger…”
Yunia cautiously grasped my middle finger.
“!!”
Using the Kegel Method, I extended my finger by infusing mana between the cells.
It didn’t suddenly stretch out dramatically, but overall, it grew by about 0.2cm.
“If you keep stimulating it like this repeatedly, it will continue to grow permanently. What we’re doing right now is just temporary.”
“This is….”
Yunia pressed my middle finger firmly, but it wasn’t soft; it had hardened.
“[Hardening]…?”
“In other words, it’s [Solidification].”
Mana fills the empty space.
But what if that mana hardens, like turning into tiny stones?
“Imagine filling a cream horn with soft, white cream cheese. If you squeeze it, it won’t feel hard. But if you freeze it and then take it out, it’ll become stiff, right?”
“Does that mean it has water-attribute magic?”
“Oh no, it’s just a metaphor. The Kegel Method is a continuous process.”
As expected of Yunia, she subtly realized that water-attribute mana could produce similar effects to the Kegel Method.
– If [Hydra] is all about being sturdy and strong, wouldn’t [Rusalka] be more about softness and flexibility…? Haha.
Hydra was considered a savior or goddess to men, while Rusalka was the same for women.
“Is this technique only available to men?”
Ludmila asked cautiously.
“Does it only work for men?”
“No, it works for all humans—or rather, any living being with mana.”
Although it was mostly used to aid reproduction, it can be applied in other ways too.
“You can even increase your height by injecting mana between your bones.”
“W-What!?”
Evangeline shot up from her seat.
“Is that… really true?”
“Yes. But there’s a significant drawback with bones.”
“What kind of drawback? Does it permanently make you taller?”
“No. Since mana fills the space between the bones, it’s extremely painful when they stretch. Unless you do it very gradually over a long period.”
“So, it can be done?”
“Yes. But there are other side effects, though we can set those aside for now.”
I pointed back to the target of the Kegel Method, a drawing of the male mana stick I had sketched on the board.
“The key to the Kegel Method is to continuously stimulate the mana. To ensure that, you need to maintain the stimulation not only through mental imagery but also through constant physical stimuli in daily life.”
I turned toward Instructor Esta, or rather to those listening to my theory through Instructor Esta’s magic panel.
“I’ll be honest with you all, it’s essentially like wearing mana-infused underwear 24/7. Not just any underwear, but ones that constantly stimulate you magically.”
There was a brief silence.
“You draw a magic circle inside the underwear, and that magic circle continuously stimulates you. If there’s any societal drawback, it’s probably… well, that.”
Being the only man in the old school building, it took me a moment to catch on to what “that” was.
“A healthy man gets excited just from a simple touch.”
Those listening through the magic panel must have caught on right away.
Underwear that causes constant electrical stimulation for 24 hours? What state would that leave the mana stick in?
“I’m sure everyone understands that part, but there are concerns.”
“What concerns?”
“Once you start, it becomes even easier for mana to drain from the mana stick. If you get hit with a mana drain, the impact will be even greater.”
It’s obvious. If the mana stick holds more mana, it becomes an easy target for mana drain attacks.
“But what if the mana infused in the mana stick through the Kegel Method forms a united front and creates a barrier? A barrier that prevents mana from leaking out of the body?”
Exactly.
It would be a thin mana barrier formed just beneath the skin, at the particle level.
– Isn’t that just a mana condom? Haha.
“…As long as you don’t lose to the suction power of a mana drain and the barrier isn’t pierced, they wouldn’t be able to steal your mana.”
This barrier is not only a defense against mana drains but also a technique for crucial moments.
“Yes, it’s a buff. A buff that temporarily expands and hardens the mana muscles you’ve trained for that critical moment.”
Buffs are usually reserved for battles with powerful foes.
“In other words, it’s the [Grand Victory Technique].”
The ultimate enhancement.
When the buff is activated and maintained, anyone can reach 180mm.
“Literally, it’s magic.”
