Naruto: Strength Through Teaching

Mutsuki looked at the sudden arrival of three messages and fell into contemplation.

He didn't expect the master-disciple system to have such a function as training missions.

So why didn't it appear when he previously formulated his training plan? Can only disciples trigger it?

Even if only disciples can trigger it, there should have been some tasks triggered before, such as Obito wanting to achieve the first in practical combat.

Mutsuki speculated that these training missions might have several conditions that need to be met to trigger, possibly related to trust levels and other factors.

Since it was the first time triggering, he couldn't determine all the conditions. The only thing currently confirmed is that the disciple triggering the mission must have enough "desire" for the mission's goal.

Looking at Obito's eager and expectant eyes, Mutsuki was very certain of this point.

"Yumi-sensei, please just agree to this one time. After taking first place, I will definitely complete the tasks you assigned with double effort, and in the future, I will follow your training plans without any complains." Obito pleaded.

He still couldn't forget the day of the competition when he lost to Kakashi in front of Rin.

"Alright," Mutsuki nodded helplessly.

"Yumi-sensei, you really are the best sensei in the world!" Obito was very excited when Mutsuki agreed.

"Let's save the compliments until after you've taken first place" Mutsuki joined two fingers and tapped Obito's head.

"Hehe, I'm just speaking the truth," Obito chuckled.

After studying for several years, didn't he know what a good sensei was?

Mutsuki had a good temper, gave interesting and understandable lectures, and was kind to students. What else could make a sensei good?

"So, Yumi-sensei, what Ninjutsu are you planning to teach me?" Obito asked curiously.

"Fire Release·Great Fireball Jutsu," Mutsuki said.

"I already know the Great Fireball; I used it in the last competition and only got twenty points," Obito said, scratching his head in frustration.

During the previous competition, he used the Great Fireball to score twenty points and temporarily took the lead. However, Kakashi then showcased Earth Release, manipulating the entire arena with elevation changes, and directly scored a perfect thirty points.

"If you want to be imposing, among the Fire Release techniques you can currently learn, the Great Fireball is the most imposing," Mutsuki said, then swiftly moved to the riverbank and began forming hand seals.

"Fire Release·Great Fireball Jutsu!"

Mutsuki gathered a large amount of chakra and, in the instant of exhaling, completely transformed it into flames through nature transformation. He continuously spewed out roaring flames.

The massive flames formed a giant fireball, ten meters high. In front of such a colossal fireball, even the 1.8-meter-tall Mutsuki appeared small, not to mention Obito, Shisui, and others. They were all profoundly shocked by the spectacle.

"Even stronger than the last time I saw it. Yumi-sensei, what kind of strength do you possess?" Shisui recalled his first visit to Mutsuki's home.

At that time, he had glimpsed Mutsuki practicing Ninjutsu, also the Great Fireball, which was extremely impressive. However, this time was even more awe-inspiring than the previous one.

Shisui instantly felt that Mutsuki's strength was unfathomable, and it wasn't certain that he had used his full power.

"Is this... the Great Fireball?" Obito stared in disbelief at the enormous fireball towering over his house.

Compared to Shisui's Great Fireball, Obito's seemed like a small fireball, and when compared to Mutsuki's, it was like a faint spark from an unknown source.

Obito found it hard to believe that Mutsuki had just used the same Ninjutsu as him.

"It's really massive. When facing such Ninjutsu, you need to be even faster and stronger," Might Guy exclaimed as he looked up at the gigantic fireball.

The immensely large fireball crashed into the river, evaporating a significant amount of water. Instantly, waves of white mist surged, enveloping the surroundings. After Mutsuki used Wind Release, the mist quickly dissipated.

Mutsuki let out a light breath and smiled at Obito, asking, "What do you think? Is the Great Fireball imposing enough?"

"It's more than enough, looks incredibly powerful," Obito nodded vigorously, thinking that if he could use the Great Fireball with a quarter of Mutsuki's scale, he might win the competition.

Mutsuki thought that the previous attack was indeed powerful, a bit ostentatious, and also quite chakra-consuming, burning a whole thousand points of his chakra.

In normal combat, he wouldn't use a Great Fireball of this scale because, at the same level of battle, it's indeed a bit challenging to hit a person with it.

Mutsuki remembered from his previous life that someone, out of boredom, had apparently counted and astonishingly found that in over seven hundred episodes, regardless of who used the Great Fireball, it had never hit a humanoid creature.

With such an exaggerated record, it's no wonder people called it the "Can't-Hit-Humans Jutsu."

"Then, give it a try yourself," Mutsuki said to Obito.

"Sure," Obito nodded, walked to the riverbank, swiftly formed hand seals, and then blew out a flame.

However, the awkward thing was that Obito's Great Fireball was only the size of two heads, a world of difference from the one Mutsuki had just displayed.

"Obito, it's okay, even if it's small..."

"Guy, spare me the comfort," Obito directly interrupted the casting, indicating that he didn't need that strange consolation.

"Do you know why there's such a big gap between your Great Fireball and mine?" Mutsuki asked.

"Is it because I'm not proficient in its control?" Obito uncertainly replied.

"There are three aspects. First, your chakra control ability is too poor, making it difficult to effectively use the limited chakra you have. Second, your nature transformation practice is lacking, preventing you from transforming a large amount of chakra into flames. And the third is your lack of proficiency in mastering the Great Fireball," Mutsuki summarized.

Immediately, Mutsuki took out a small booklet and handed it to Obito, saying:

"This is some experience I've gathered from practicing the nature transformation of fire attribute chakra. If you read, memorize, and practice according to this booklet, it should help resolve the issues with nature transformation."

Compared to Shisui, Obito's foundation was much weaker, so in the first month, Mutsuki essentially helped Obito rebuild his foundation and also taught him the Great Dragon Fire on the side. That's why he hadn't given Obito the nature transformation manual until now.

If it weren't for the sudden appearance of a training mission, Mutsuki had planned to give it to Obito next semester.

After all, teaching Obito too much at once would be overwhelming for him.

[You have gifted your disciple the Nature Transformation Manual for Fire Attribute Chakra. Due to the disciple's deep appreciation, a large critical reward is triggered. Obtained Fire Release: Intelligent Hard Work (Mastery).]

Mutsuki didn't expect Obito to be quite effective, directly granting him mastery-level proficiency in Fire Release.

Intelligent Hard Work was not an ordinary Fire Release technique; it was a B-rank Fire Release Ninjutsu performed by Kakuzo's Fire attribute mask. Its power was extraordinary, and when combined with Wind Release: Pressure Damage, which he had drawn before, it could instantly create a sea of flames that would burn down an entire forest.

A plethora of training memories appeared in Mutsuki's mind. In an instant, Mutsuki had a sensation, as if he had silently dedicated thirty years of intensive training to mastering Intelligent Hard Work in some unknown corner. Throughout those thirty years, he had focused solely on perfecting this one Ninjutsu, bringing it to a level where he could wield it effortlessly.

"I'll definitely study it every day!" Obito exclaimed, cradling the manual as if it were a precious treasure.

"There's one more thing – let's work on enhancing your chakra control," Mutsuki said with a smile.

Once Obito completed the basic climbing tree and walking on water training, the advanced water-walking exercise plan he had developed on Asuma became relevant.

Although Obito didn't know exactly what Mutsuki had in mind, recalling the painful weekend training sessions made him suspect it was likely another grueling yet highly effective training regimen.

However, now he had to brace himself because this time, he had requested it himself.
