Step by step

"Okay, I will send all the data right away, or rather, shouldn't you just visit my place? I will get all the data there." 

After Maya read Masa's plan, she made up to give all of the research data about the Magic Calculation Area that he needed for his plan. "But even so, our research hasn't fully discovered what it is yet." 

"It's fine. I only need the starting point." 

"That said, what about the energy issue? Have you solved the "Three Great Puzzles of Weight Systematic Magic?" 

"...you seem more cornered about this plan than I am." 

"I do, so how long is it?" 

"It shouldn't take a decade." 

"Really? That's fast!" 

"I am a genius, after all." 

"How cheeky~!" 

Maya laughed as she pulled his cheek happily, which made Masa hug her, thinking that she was so cute, before burying his face against her hair, thinking that the scent of her hair was so nice. 

"But you know to mention it, "Three Great Puzzles of Weight Systematic Magic," huh?" 

Modern magic is based on studies of supernatural powers (magicians in the early period were referred to as such). In this, Magic is categorized by its effects. "Acceleration (Speed), Weight," "Movement, Oscillate (Vibrate)," "Converge, Diffuse (Dissipate)," and "Absorption, Emission (Release/Disperse)" are known as the 4 System-8 Type Magic (Systematic Magic). However, there are some exemptions to this category.

Still, magic that is not part of the 4 System/8 Type magic is broken down into three other categories.

First, "ESP" (Extra Sensory Perception), or Perception-type Magic.

Second, Non-Systematic Magic, Magic that does not aim to alter phenomena by temporarily rewriting the body of information associated with phenomena, "Eidos," but aims to control the Psion itself. However, considering that most forms of Magic are systematic in nature, Modern Magic has become synonymous with Systematic Magic. Psion manipulation is technically also a part of the 4 System/8 Type and is not limited to Non-Systematic Magic.

Third, Outer-Systematic Magic is magic that does not manipulate physical objects but the spirits themselves.

In conclusion, modern magic can be categorized into four major categories: Systematic, Perception, Non-Systematic, and Outer-Systematic.

Aside from Outer-Systematic, Masa was well-versed in all major categories, but Maya was well-versed in Outer-Systematic as the Yotsuba family, which came from the 4th Research Lab, which specialized in Mental-Interference magic research. 

Still, their current topic was the "Three Great Puzzles of Weight Systematic Magic," but while Masa had the ability of the Ton Ton no Mi, which allowed him to manipulate a weight in a ton metric, his focus had always been on electromagnetism, which was part of the four fundamental forces, as the specialty of the Isshiki family had always been their bio-electricity, which often made them be called the Electromaster. 

"No, I haven't solved the Three Great Puzzles of Weight Systematic Magic, nor do I have much interest in it since it isn't my expertise." 

The Three Great Puzzles refer to three spells that are theoretically possible with Weight Magic but are currently impossible to achieve; the three puzzles are:

1. Realization of a Gravity Control-Type Thermonuclear Fusion Reactor

2. Actualization of Generalized Flying-Type Magic

3. Development of a perpetual motion device based on the model of unlimited inertial expansion

When Maya saw Masa's plan, she instantly fell in love with it, but to do this plan, an enormous amount of energy was needed, so she thought that Masa could solve the realization of Gravity Control-Type Thermonuclear Fusion Reactor, which could be used as a source of energy for his plan. 

"More importantly, thermonuclear fusion reactions are far from being efficient and large enough to complete this plan." 

The thermonuclear fusion reactor was good but was far from being subtle and hidden. 

Moreover, it wasn't suited to his expertise, which was electromagnetism. 

"Then?" Maya clung to him before her hand stretched down toward his sensitive area, caressing it softly with her gentle hands. "Tell me~!" 

"...I regret telling you about this plan." Masa sighed, feeling Maya's gentleness, which made him soften and feel comfortable. 

"But you need me to do the research on the Magic Calculation Area, right? I will support you on this plan. Come on~!" 

Masa turned his gaze to Maya, who looked at him with a cute expression despite being a mature woman, which made him helpless and kissed her cheek. 

"Magnetic field." 

"...magnetic field? Are you going to use magnetohydrodynamic?" 

Magnetohydrodynamics is the study of the kinetics of electrically conductive fluids (liquid or ionized gas) in the presence of electromagnetic fields. 

Using this study, the world has created the UMD or Magnetohydrodynamic Generator, which is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.

An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate an electric current.

However, it is different from traditional electric generators in that they operate without moving parts (e.g., no turbines), so there is no limit to the upper temperature at which they can operate. 

At the same time, it is also known to have the highest known theoretical thermodynamic efficiency of any electrical generation method.

In this world that forbids the existence of any nuclear reactors, there is no doubt that everyone tries to search for other sources of clean energy, whether it is solar, wind, geothermal, etc. 

Naturally, the MHD generator is also one of them, but its development is limited due to how complicated it is. 

Yet, Masa said that he wanted to use this source of energy for his plan.

"...." 

Maya was silent, but then she nodded. "It's within your expertise, but if you fail, you might destroy the biosphere, causing an error on the planet's magnetic field, which causes solar radiation to bombard the planet, increasing cancer cases, radiation sickness, technological disturbances, and blackouts on a global scale.

"But... if all of us die, then it is all good." 

It might be sad when she thought she couldn't be with him forever, but when she thought that all of them would die, then it was all good. 

"Still, if you can develop this generator and combine it with your family's magic, then your family will be richer." 

If Masa could develop another source of clean energy, then there was no doubt the existence of a magician would become even more important to the world, considering how the world was lacking in energy. 

Rather, among all the magicians in this world, the Isshiki family was the only one capable of commercializing their magic. 

Twenty years had passed from the idea of commercializing magic to changing the idea of a magician as a weapon, but unfortunately, no one could ever do it except for the Isshiki family, who used their magic to enter a cyber security market. 

Yet, if Masa developed another magic that could become a source of energy, then the value of the Isshiki family would become even more valuable in the eyes of the country! 

At the same time, a danger would also come to this family, as it was hard to search for a magician who was capable of mastering bio-electricity as the Isshiki family, which was born to wield such magic. 

"No, the magnetic field is just beginning; the real thing is behind that." 

"What is it?" 

"Slow down, okay? Everything is step by step, and more importantly, I have to get permission to send a satellite first." 

The energy problem was solved, and the research on the Magic Calculation Area was halfway done, so what was left was a calculation and a method to transform all a human being into a magician; fortunately, he had a Zoan-type of Devil Fruit, which was a magical Devil Fruit that could transform a human being into a respective creature of that Devil Fruit, and an Evil Piece, which allowed to transform any forms of living beings into a Devil. 

So, if a human being could gain a trait of a certain creature by eating a Devil Fruit, or any living being became a Devil with just an Evil Piece, then why couldn't Masa give the trait of a magician to all humans in this world? 

Still, to do that, he needed a method to do a mass transformation, which was a little troublesome, especially when he might also affect other creatures from animals and plants, which might turn them into monsters. 

Yet, Masa felt that it was okay since his family was strong, after all. 

"...sorry, I can't help you with the satellite problem." 

The Yotsuba family might be powerful, but it didn't mean they were omnipotent since even if they were strong, their influences could affect various important sectors within this country. 

Rather, in terms of versatility and balance of power, the Yotsuba family was below the Isshiki family, who got their hands on the banking sector. 

Maya knew that those satellites that Masa wished to send off were important for his plan, but unfortunately, she couldn't help him. 

"It's fine." Masa knew that the ones who tried to stop his satellites were mostly from another country instead of domestic. "Still, I will build the Magic MHD reactor first." 

"I will help you with that." 

The change in the perception of a magician as a weapon was probably the goal of every magician, but Masa and Maya couldn't care about all of that since one couldn't change the minds of others unless they manipulated them with mind magic. 

Still, there was no doubt that this move of his to change the perception of people towards magicians being used by the military would touch the nerves of many people. 

Yet, so what? 

Maya had made up her mind to kill all of those who hindered him, but before that, let's solve the problem before them first. 

"Masa, are you okay?!" 2x

"...." 2x
