Layering Two Devil Fruits
'I don't know what devil I just ate. They never showed it in the manga. I guess I'll have to wait a while' Lee thought sadly( :( ). 'Though I have a pretty good idea of what it could be...'
A few days later...
Lee looked at his finger. This time there was no fire or heat. Instead, his pointer finger was invisible. 'Oh my god yes. I have Absalom's clear clear fruit. It's one of the most coveted fruits in the One Piece world.'
One of the members of the Strawhat Pirates, Sanji, was willing to sacrifice his ability to swim for the ability, and according to the One Piece wiki, the fruit currently belongs to a member of the Blackbeard Pirates, Shiryu. Thus the suke suke no mi was definitely a valuable fruit especially for espionage and other hobbies...
He could get away with ninety-nine percent of things. After all how many people would be able to sense and fight an invisible man?
Lee focused on separate parts of his body to turn invisible. He couldn't turn any more than half his body invisible or the baby cam would spot it.
A few weeks later...
He finally got the hang of turning selected body parts invisible. Now it was time to multitask and use both devil fruits. He focused on these two pointer fingers. His left pointer immediately combusted into flames. His right pointer remained the same.
He had to multitask and split his mind into two. As he concentrated his right pointer flickered on and off, from visible to invisible. A few days later he finally got the hang of multitasking.
'Now it's time for the ultimate test. If this succeeds I will be one of the top dogs.'
He began concentrating onto his hand. He spread his fingers out and began concentrating. Hours passed but nothing happened. Then his hand disappeared. Although it was gone, Lee could still feel an intense heat radiating from his hand onto his skin. He had succeeded!
'Invisible fire. Highly destructive and equally as stealthy. It's similar to one of Genryusai Shigekuni Yamamoto's Bankai abilities or one of the deadliest fighters from the webtoon Kubera, the dragon Taksaka.'
Lee then thought about all the places he could sneak into and all the undetectable killings he could do.
In addition, now that he could create invisible fire he could finally practice creating a larger amount of fire and shaping them to create his own moves. Unlike Ace or Sabo, who were in their own right skilled fighters, he was going to go for higher quality over quantity. Instead of spraying fire, he knew it was better to concentrate it and raise its temperature as high as possible.
'If I recall correctly the maximum temperature fire can reach was about 6,000 degrees Kelvins or more than 10,000 degrees Fahrenheit when burned with a mix of certain substances. But knowing manga physics and Oda logic, the mera mera no mi should allow me to skip the chemicals straight to the process of combustion and creation of heat. The magu magu no mi doesn't seem to be much stronger with the highest temperature being a little more than 2900 degrees Fahrenheit for komatiite magma. Not that it doesn't have its own advantages. Magma obviously has more mass and density than fire. Most likely Ace lost to Akainu because of a combination of magma smothers fire and Ace's inability to realize that temperature was what really matters.'
In other words, size doesn't matter it's what's on the inside that counts. Ace loves giant fists of fire and creating a miniature sun. He kind of got the compression part but did not actively raise the heat.
As he stared at his hand an invisible bulge of fire emerged from his palm and formed a sphere. The sphere of invisible fire hovered in front of Lee's face. It felt like a part of him, like an extra arm or foot or hand or leg or muscle. Unfortunately, it felt like a newly developed limb which meant he would have to practice using it like he would his fleshly body.
He made the sphere float five feet away. There was no response from the maids or anyone. While the thermometer did go up it wasn't as though anyone was going to come inside to check on him any time soon unless he started crying as a normal baby would under intense oven-like heat.
Lee smiled and began shaping his flames. He started with what he considered to be the most basic: the fireball. Although other people could not see it the sphere of fire was merely what it sounded like a sphere of fire. It burned wildly and wobbled like a water balloon.
He mentally clenched his fist or in this case the orb of fire. It shrunk to a wobbly ball three inches in diameter. He concentrated the core of the beginner's fireball and began working his way outward towards the surface.
When the fireball seemed to be fairly well rounded to Lee he began moving it around the room. He managed to get it to move in a general direction but the fireball bounced up and down, and left and right.
Over the course of the next few weeks, he would practice adding more mass and heat to the fireball while compressing it onto a fireball before moving it around the room in straight lines, zig-zags, diagonal, curves and more.
Two months later he managed to master the humble fireball...
The development of his fire control was similar to how a child developed. Although children could move their arms and other limbs most of it would be flailing it around. They simply didn't use to more complicated movements yet.
'Well, at least the new maid is cute.'
It seems that a new maid was taking care of him now. The new maid was petite, she had no breast, waist or butt. She could not be 18 yet, right? Anyway, she seemed to be of Hispanic and European origin. She had the classic blonde hair with blue eyes but had caramel-like skin too natural to be tanned. Luckily for her, she still had a pretty face and with her distinct features. She could be an eight out of ten in the future. Her body was not as developed as an adult woman should be which means she was obviously much younger than the previous maid who was standing right beside her.
There was another much taller maid standing beside the new maid. She was nearly twice as tall and had a stern face. There were very faint wrinkles on her forehead but she looked to be in her mid to late thirties. Her body was well proportioned with large breasts, with a slightly thick waist and a large butt that showed through her maid outfit.
"Lydia. Show me what you can do", said the older maid. Her words were straightforward and direct. She was obviously one of those strict, but successful workaholics.
"Yes Ms. Bennett", the new maid said with a slight hint of nervousness.
'Ah so the older one has the last name, Bennet and the other is Lydia' thought, Lee. 'Oh boy here comes the good part.'
Lydia began gently tugging on the rims of his shorts and diapers. Previously he could not see the other maid taking off his underwear, but now that he could see, he was thrilled.
As his entire lower body was exposed to the air he felt a shiver down his back. It was such a compromising position, so shameful and so free. Lee felt a strange sort of pleasure as Lydia wiped his nether regions with a small and soft towel. There was a strange satisfaction from a pretty young girl serving and cleaning his private parts. He never had a chance to do something like this and in a few years, he never will have any more chances.
By the time it was over, he felt free and relaxed. There was no sexual pleasure, but he would engrave every day into his mind.
'I am so going to enjoy this' he thought satisfyingly as the two maids left. 'It's too bad here's no breastfeeding anymore and I just developed my eyesight.'
He waited for a few minutes until he was sure they weren't going to walk in all of a sudden and scare him. It was now time to practice the more advanced fire spear.
He created a fire sphere into the air and began to stretch it out. As it was stretched out he mentally carved out the shape of a spear and began filling it up with more fire. The practice with the fireball had paid off. Although it was a new movement the only difference was reshaping the fireball for a different purpose. The hardest part was sharpening the tip of the fire spear and compressing a great deal of fire in the edges.
Next was the hard part, spinning it. As he began concentrating his little infant brain began squeezing and shaking. Tiny beads of sweat dripped from his forehead and temples.
'This must be how a psychic must feel like.'
The spear began slowly rotating. It began moving faster and faster until it began spiraling like a football would in the air.
"Whew."
His concentration broke and the spiraling spear dissipated.
'That's too bad. Well, I did it once and I can do it again.'
CREATORS' THOUGHTS 
WetDragon
WetDragon So many people have doubts about the dfs I chose. Well I didn’t. I pulled up a df random generator bc the point of the story is And you guys should be glad the mc doesn’t have the wolf fruit or bane fruit although that’s subjective. Anyway been a busy week. This week and next week will be more relaxing. And guess what. I was going to give him op fruits later, but now I’m purposely going to reject offense focused fruits until later on in the novel just to be a dick. ( :p)
