Chapter 55: New Body Instant Technique
Shisui wiped the sweat from his forehead, leaned against a large tree, and began to rest.
Nearby, Might Guy and Obito had just finished their respective training sessions and were preparing to start their spar—a battle that would determine how many questions they'd be assigned to solve afterward.
"Today's youth... is ready to be unleashed," Might Guy said seriously, muscles tensing as he readied his stance.
In truth, Guy was under even more pressure than Obito. He began with a debt of fifty questions—his only way to reduce that number was by landing clean hits on Obito.
I absolutely can't let it go over thirty, Obito took a deep breath, his eyes filled with determination—and a tinge of fear.
If he went over his limit, he wouldn't have time to go out with Rin on Saturday night.
"Begin!" Mugetsu called out.
The moment the words left his mouth, Might Guy charged forward like a missile, launching into a rapid, overwhelming Whirlwind Kick.
Obito immediately widened the distance, doing everything he could to avoid taking hits.
After a few moments, Shisui sat down and watched the two spar with full intensity. A faint smile appeared on his face.
"It's great… getting along well during normal days, then going all out during sparring to improve together."
This kind of friendship felt genuinely precious to him.
The moment he said that, Obito almost tripped.
What friendship?
If he didn't fight like his life depended on it, he'd be buried under a mountain of problem sets and "improvement drills" by nightfall.
If only he could defeat Shisui, Obito would've begged Mugetsu to add him into this hellish training cycle too.
While he didn't fall, Obito's momentary distraction was enough—Guy landed a hit cleanly, adding one more problem to his growing total.
Obito snapped out of it and immediately focused, pushing aside all stray thoughts to face Guy's onslaught.
Five minutes later, Mugetsu, standing nearby, announced the results.
"Obito, thirty-five problems. Guy, fifteen."
"…Thirty-five," Obito muttered bitterly. That was five over his limit.
He felt like collapsing on the spot. There went his plan to hang out with Rin tomorrow night.
Might Guy didn't look much better. He'd taken too many hits. Obito's rapid progress meant Guy could no longer cut his number down to ten like before.
"It's alright," Mugetsu said with a light smile. "If you can't finish today, you can always pay in installments. Spread it over seven days, and you'll only have to do five a day. Of course, the interest will be four more questions."
Doing too many in a single day wouldn't be productive—especially for Obito's brain. He'd forget half of it before learning anything useful.
Obito hesitated. Originally it was thirty-five, but with installments it'd become thirty-nine.
Still, finishing them all in one go would leave him drained, and he wouldn't be able to enjoy his time with Rin.
"…Alright. I'll split it over seven days," he replied weakly.
Though reluctant, he had to admit—installments were addicting. They really did make life easier.
Mugetsu nodded and updated Obito's latest repayment plan in his scroll.
"Today's work, today's finish," Might Guy declared. He had no intention of paying in installments.
Mugetsu nodded in approval. Whether they realized it or not, these daily problem sets had already improved both their theoretical knowledge and motivation.
This training method wasn't just effective—it was efficient.
In fact, the questions didn't even need to be limited to the standard Academy material. They could be tailored for broader knowledge absorption through combat-reflection learning.
After a short rest, Shisui resumed his own training.
Right now, his focus was on two techniques: the Body Flicker and Genjutsu.
Both were new to him, but his learning speed was unusually fast—faster even than when he first began learning Fire Release.
[Disciple Uchiha Shisui has diligently trained under your guidance and has made notable progress in strength. You have received the reward: Shave (Proficient Level).)
Mugetsu blinked in surprise when he saw the reward.
"Shave"? That's not a technique from the Naruto world... isn't that from One Piece?
As a flood of training memories related to the technique poured into his mind, Mugetsu immediately understood what had happened.
This was Shave, one of the Six Powers Mugetsu remembered—but now, it had been modified by the system into a Naruto-compatible version. It was both a Taijutsu and a Body Flicker Technique, requiring the use of Chakra.
Mugetsu nodded in satisfaction.
If it had been the original Shave from the One Piece world, his current body might not have been able to handle it. The monsters in that world were simply too powerful.
He compared the version of the Body Flicker Technique he had previously mastered with the newly acquired Shave.
The result was clear—his old Body Flicker was completely outclassed.
"I'll be using Shave as my new Body Flicker from now on," Mugetsu concluded inwardly.
"Shisui," he called out, smiling, "I've been watching your training closely. Compared to two months ago, your strength has improved significantly. Keep it up. If you stay consistent, I'll teach you an even more powerful Body Flicker Technique."
The golden goose had delivered again, and Mugetsu's mood couldn't be better.
"A stronger Body Flicker Technique?" Shisui's eyes lit up, full of curiosity and anticipation.
He was deeply interested in movement-type Ninjutsu and felt that Body Flicker techniques were especially suited to his style.
"Yes. But you need to focus more on physical conditioning," Mugetsu nodded. "This Body Flicker Technique is classified as Taijutsu. Without sufficient lower-body strength, the strain will be too much for your legs."
After all, it was a technique originating from the One Piece world. Even though it used Chakra now, the physical demands were still high.
Not just Shisui—Mugetsu himself needed to focus more on his physical training. His Ninjutsu loadout was already quite luxurious for the early game, and this new movement technique was the perfect addition.
"Teacher Mugetsu, I think I've improved a lot too! Can you teach me as well?" Obito asked with a grin, scratching the back of his head.
He didn't care much for practical use—he just thought Body Flicker looked cool.
If only he'd known it during the Youth Ninjutsu Competition… he wouldn't have needed to walk on stage. He could've made a flashy appearance like Kakashi—whoosh.
"Of course," Mugetsu said, nodding without hesitation.
"Yes! Teacher Mugetsu, you're the best teacher in the Ninja World!" Obito shouted joyfully.
"Teacher Mugetsu, I've been training hard too," Might Guy chimed in, not wanting to be left out.
"Sure. You can all learn it," Mugetsu said with a warm smile.
"But there's a condition," he added. "If you want to learn this Body Flicker Technique, you'll need to get first place in the year-end exams."
"But both Guy and I are in the same grade. Doesn't that mean one of us is guaranteed to lose?" Obito asked, puzzled.
"Then win the next exam," Mugetsu replied calmly. "Or… you can complete the Taijutsu challenge I'll set. If you succeed, I'll teach it to you regardless of your rank."
"Is the challenge difficult?" Obito asked cautiously.
"You probably can't keep up with it yet," Mugetsu answered bluntly.
Obito fell silent.
That meant the only viable way left… was to get first place in his year.
He now had another reason to aim for the top in the final exam.
He looked over at Might Guy, who responded with a brilliant smile and a thumbs-up.
You're not actually planning to take first place, are you? Obito's competitive spirit ignited.
Fine then—first I'll deal with Might Guy. Then I'll beat Kakashi. After that… I'll be the genius Uchiha Obito!
Just as that fire burned inside him, Mugetsu handed him a sheet of paper.
"Here's your assignment. Remember to finish it properly."
The flames in Obito's eyes were instantly extinguished.
Looking at the mountain of problems before him, his head began to ache again.
"And here's yours, Guy," Mugetsu said, handing over another test paper.
Looking at the black text printed on white, Might Guy's wide smile slowly faded. His formerly firm thumbs-up drooped into a thumbs-down.
Even a man of steel had his breaking point.
