"Hmm, now that the Breathing Technique has reached the Beginner level, it can indeed accelerate the progress of the Eight Inner Gates," nodded Mutsuki.
Right now, Guy is still far from reaching the Constant realm, so he temporarily focuses on the Eight Inner Gates to effectively enhance his strength.
The Breathing Technique and the Eight Inner Gates can complement each other. The Breathing Technique can strengthen the body, and the stronger the body, the stronger the effect of the Eight Inner Gates.
"I'm not calm enough in battle, I tend to be impulsive," Obito thought for a moment and said.
With Mutsuki's question, he could confront his own shortcomings.
Obito himself knew this flaw, which is why he lost against Guy more battles than he had won.
He's prone to getting carried away, which leads to battles without strategy and ultimately results in defeat.
"Since you know, you have to be more careful in battles from now on," Mutsuki said, patting Obito's hair.
Obito's performance is really unstable, sometimes he plays well and wins battles even when his strength is at a disadvantage, but most of the time he just squanders himself.
"I didn't understand your strength, sensei, and made a wrong judgment," Kakashi recalled and said.
Honestly, he felt that his performance in that mission's encounter battle wasn't bad.
Being restrained was inevitable. In that situation, not only himself, Kakashi felt that any Konoha Jonin would have ended up the same. The opponent was obviously not an ordinary Jonin, and it was an ambush. How could he defend against that?
Moreover, after breaking free, Kakashi quickly helped his teammates deal with the enemy, freeing up more fighting power.
Kakashi felt his only mistake was underestimating Mutsuki's strength. He didn't know Mutsuki was so strong that he could take out two Jonin opponents even while protecting him.
"After all, we've only known each other for a short time. Let's get to know each other more from now on," Mutsuki said with a bright smile.
"Yumi-sensei, did you use your full strength in the last battle?" Kakashi asked after some thought.
Raised by Sakumo Hatake, Kakashi is different from Obito and Guy. His knowledge is broader, and he knows the true strength of strong individuals.
After returning, he recalled many puzzling points from that battle. Mutsuki's initial performance and his final performance were completely different levels.
While Mutsuki's early Lightning Release and Wind Release techniques were impressive, they paled in comparison to the Fire Release Wind Release Combination Jutsu later on.
So Kakashi developed a hypothesis: perhaps Mutsuki's strength is even greater than what he showed that night, but to train them, he didn't directly kill all the enemies.
Kakashi's question also aroused the curiosity of Guy and Obito. Even after following Mutsuki for half a year, they still didn't know Mutsuki's limits.
"You guess," Mutsuki replied with a grin.
Kakashi: ...
"Then you definitely didn't use your full strength. If you had used that Fire Release from the beginning, all the enemies would have been burned to death long ago," Obito said confidently.
Even if one day Mutsuki told Obito that he was actually the reincarnation of the Six Paths Sage, Obito wouldn't be surprised. After all, Mutsuki is his omnipotent sage.
"Correct, the reward is a candy," Mutsuki tossed a candy to Obito.
"Hehe," Obito caught the candy and grinned foolishly, proving once again that he understands Yumi-sensei the best.
"Yumi-sensei, you are an Academy sensei, right?" After receiving Mutsuki's confirmation, Kakashi couldn't help but ask.
"Why do you always ask strange questions, Kakashi? Of course, Yumi-sensei wouldn't be anything other than a school sensei," Obito complained.
"Kakashi wants to know why someone with my strength is still an Academy sensei," Mutsuki smiled.
Kakashi ignored Obito and nodded.
"Well, there are many reasons, but the main one is because I enjoy teaching. The thing that makes me happiest is seeing the progress of the students I've taught," Mutsuki explained with a smile.
This answer was somewhat unexpected for Kakashi; he thought the reason would be more convoluted, but it turned out to be so simple.
"Alright, summary over. Everyone, start training. Training in the morning, missions in the afternoon," Mutsuki said, closing the discussion.
Then Mutsuki began to arrange the training for each disciple.
"Kakashi, you've almost mastered False Darkness. I have a good new Ninjutsu to teach you," Mutsuki said to Kakashi.
After speaking, Mutsuki raised his hand and condensed Chakra in his palm, swiftly completing Nature Transformation and shape transformation. Dazzling purple lightning enveloped Mutsuki's palm.
"It seems similar to Chidori from that day," Kakashi felt familiar with this new Ninjutsu.
"Yes, this Ninjutsu is actually an improvement on Chidori," Mutsuki nodded.
Originally, Kakashi's Chidori first transformed into Raikiri, and then, after losing the Sharingan, it was improved into Purple Electricity. Mutsuki skipped this step and directly learned Purple Electricity, surpassing the Kakashi from the original world by thirty years.
"Compared to Chidori, Purple Electricity doesn't require hand seals, has greater power, and is more flexible to use, but it's slightly slower," Mutsuki explained.
After speaking, Mutsuki demonstrated the power of Purple Electricity, which could cut through rocks like tofu and release a large-scale electric attack in the surrounding area.
"Isn't sacrificing speed for power and flexibility somewhat inappropriate?" Kakashi felt that speed was still more important.
Although there are few ninjas with powerful defenses, most ninjas are generally not slow.
Mutsuki didn't explain but instead grabbed Kakashi, and with Thunder Breathing, unleashed a burst of speed, allowing Kakashi to experience extreme speed.
"Was that fast enough? Could you keep up?" Mutsuki asked as he let Kakashi down.
Kakashi instantly understood Mutsuki's intention. He recalled Mutsuki's speed when using Chidori, which was also very fast.
Kakashi felt an indescribable feeling in his heart. It seemed that Mutsuki had intentionally improved the ninjutsu because of him.
Kakashi was genuinely a bit surprised and overwhelmed by the favor. He had only become Mutsuki's disciple for less than half a month, yet Mutsuki was already considering his needs so carefully.
It wasn't that Kakashi was conceited, but Mutsuki's modification of ninjutsu did raise some doubts. Mutsuki could definitely be considered a speed-type ninja, so how could he possibly decrease the speed of ninjutsu to increase its power?
After Kakashi's training ended, Mutsuki gave him a piece of calligraphy he had written himself.
[You have gifted your disciple a handwritten calligraphy. Due to the disciple's deep gratitude, you have received a critical hit reward, gaining the Earth attribute Chakra Nature Transformation (Proficient level).]
Having become more familiar with Mutsuki and being saved by him once, coupled with the emotions stirred up by learning Purple Electricity, Kakashi received a pretty good reward.
As Kakashi pondered the meaning behind the calligraphy, Mutsuki revealed a smile of satisfaction, like an old farmer at harvest time.
Things were looking up with the critical hit, and an increase in trust level was only a matter of time.
In the afternoon, Mutsuki took the disciples to the Hokage Building; after all, Chakra still needed to be enhanced.
