Naruto : Ninja school teacher, I can become stronger by teaching

"I still have to do twenty-five problems every day for ten consecutive days to pay off all the installments," Obito calculated the number of problems he was burdened with on the way to the Southern Forest.

"I won't even finish by the time the holidays start…" Obito scratched his head, feeling a bit stressed.

Not only was there a lot of old debt, but he also accumulated new debt every day, which was truly difficult to bear. Obito felt like he'd be doing problems every day for the rest of his life if this continued.

Once Obito arrived, Muyue called Might Guy and Obito over and said, "Next week is the final exam, so I'm changing the training plan."

"Changing the training plan? There's only one week left, isn't it unnecessary?" Obito was a bit nervous.

The last change went directly from thirty-plus problems per battle to over a hundred per battle, and Obito was truly scared.

"Combat taijutsu is temporarily canceled; you'll each train individually," Muyue explained the specific change, then smiled at Obito. "Are you sure it's unnecessary to change?"

"I think it's very necessary," Obito replied with a serious expression.

Combat wasn't important, nor were the problems, but not having combat and not gaining new problems was very important to him.

"Teacher Muyue, your decision is simply great, it's a stroke of genius, extraordinary and well-planned…" Obito used all his knowledge to butter him up, and by the end, he didn't even know what he was saying himself.

"You're flattering me too much," Muyue lightly tapped Obito's head. "There's one more thing: even though there's no combat now, the previously assigned installment problems must be completed on time."

Obito covered the spot where he was tapped and chuckled, "Mission accomplished, guaranteed." If a single tap could reduce the number of problems, he'd rather be covered in bumps than do problems for so long.

"What are your thoughts, Guy?" Muyue asked.

Obito nervously looked at Might Guy, deeply afraid that Might Guy would say something bad.

"I think it's great too!" Might Guy quickly replied, afraid Muyue would misunderstand him. Might Guy only remained silent because Obito had already spoken; what sane person would enjoy doing problems?

Obito breathed a sigh of relief, smiling and giving Might Guy a thumbs up. Might Guy nodded, also showing a bright smile and giving a thumbs up. They had reached an agreement.

"Train hard, both of you. This week I won't interfere; you can train as you wish, however you want, and leave whenever you want," Muyue said with a smile.

"That's amazing!" Obito felt like Muyue's body was glowing.

"Shisui, come here for a moment," Muyue called Shisui, who was training.

Shisui stopped his training and walked over to Muyue.

"After a month of intensive training, your body has become much stronger. You can now begin preliminary training for the new Body Flicker Technique," Muyue said.

For this past month, Shisui had temporarily set aside other training and focused entirely on physical conditioning. The massive training volume brought very obvious results; Shisui's body was much stronger than before. Because of the System's secret medicine to repair his body and eliminate hidden injuries, Muyue could push Shisui to his limits every day. Coupled with Shisui's talent in the Body Flicker Technique, Muyue felt it was time to teach him Soru.

Hearing about the Body Flicker Technique Muyue mentioned before, Obito and Might Guy instinctively began to pay attention to Muyue.

"Didn't you say you had to get first place in the practical assessment?" Obito asked.

"This was a previous reward for Shisui, and do you think Shisui won't get first place in his grade?" Muyue replied with a smile.

Obito thought about it, and it made sense. If he were placed in the first grade, he could easily dominate, let alone Shisui, who was even stronger than him. With Shisui around, the first-year practical exam already had a predetermined outcome before it even began, with no suspense whatsoever.

Muyue grabbed Shisui's hand and, with a single Soru, appeared over ten meters away. Obito watched Soru's performance, which was like instantaneous movement, and couldn't help but show a look of yearning. If he could use such a Body Flicker Technique, how cool would he be normally? When entering the classroom, others would see him just walking in, and he would instantly appear in his seat. If the teacher asked him to come to the podium to answer a question, he could instantly disappear and reappear on the podium, startling the teacher. Helping elderly grandmas and grandpas walk would also be faster, directly letting them experience the feeling of wind.

"I must get first place in the practical assessment, let Rin know I've become strong, and make that annoying Kakashi never dare to look down on me again," Obito secretly vowed in his heart. He had been taunted by Kakashi too many times; this time, he had to prove himself.

"What incredible speed! If I master this Body Flicker Technique, I might even have a chance to defeat Kakashi!" Might Guy thought to himself as he watched Muyue instantly disappear and reappear in the distance. His speed was fast for Obito, but it wasn't quite enough against Kakashi. Might Guy felt that if he learned this Body Flicker Technique, he could catch Kakashi off guard with his speed. Even if he couldn't defeat Kakashi, he wouldn't be as embarrassed as last time.

"To defeat Kakashi, I must obtain this Body Flicker Technique, and I must take first place in this practical exam!" Might Guy was already boiling with excitement, wishing he could skip this week, skip the theoretical exam, and immediately proceed to the practical exam.

Muyue, observing Obito and Might Guy from the corner of his eye, nodded inwardly. This was precisely the effect he wanted to achieve. Sometimes, explicitly stipulating training content isn't as effective as letting disciples unleash their subjective initiative. With the Body Flicker Technique as a reward bait, there was no fear of a lack of motivation. Plus, with Might Guy, that incredibly self-disciplined training maniac, there was no fear of Obito slacking off without supervision. Seeing his classmate and rival Might Guy training intensely, could Obito really leave with peace of mind?

"This Body Flicker Technique is called Soru. Its main difficulty lies in repeatedly bursting chakra in a short period to strengthen the body and achieve high-speed movement," Muyue began to focus on teaching Shisui the Body Flicker Technique.

Soru in One Piece relies on the reaction force generated by repeatedly stomping the ground dozens of times in an instant to move at high speed. Muyue felt it was a bit absurd when he first watched the anime, but thinking about it carefully, with the physical capabilities of the One Piece world, it might indeed be possible. The Ninja World version of Soru, modified by the System, was very ninja-like; Muyue felt that if it had a different name, it would simply be a native taijutsu. The Ninja World version of Soru does not rely on the reaction force generated by stomping the ground but rather on using a special chakra technique to strengthen the legs multiple times when quickly stepping on the ground, thereby bursting forth with incredibly high speed. It was clear that the core of the Ninja World version of Soru was that special chakra technique, which was very ninja-like.

"Strengthening multiple times in a short period?" Shisui was a bit surprised; this was the first time he had heard of such a technique. No wonder Muyue wanted him to train his body for a month. The Body Flicker Technique he learned before would cause fatigue even with a single reinforcement, and this Soru sounded much more advanced than the previous Body Flicker Technique. He was very much looking forward to the upcoming training. If he mastered this Body Flicker Technique, his speed would definitely increase significantly.

Please don't keep the book unread, everyone. These are crucial times recently, and after this period, the good days of massive updates will arrive!
