"I'm currently focusing on mastering these two," Kakashi nodded.
Currently, Kakashi relied mainly on swordsmanship and Lightning Release during battles, with Earth Release serving as a supplementary role.
"I'm not very skilled with short blades, but I can teach you Lightning Release first," Mutsuki thought for a moment and said.
"Follow me. Decide which Ninjutsu you want to learn," Mutsuki led Kakashi to the depths of the training ground, amidst the dense forest.
"Lightning Release: False Darkness!" Mutsuki swiftly performed hand seals and then expelled a massive lightning spear from his mouth, instantly piercing and knocking down all the trees within twenty meters in front of him, leaving charred marks at the points of impact.
"Such powerful Lightning Release Ninjutsu!" Kakashi couldn't help but praise as he looked at the fallen trees, his admiration for Mutsuki growing even stronger.
According to Kakashi's observations, Mutsuki is definitely an elite among Jonin, excelling in both Taijutsu and Ninjutsu.
"Lightning Release: Chidori!" Mutsuki, without resting, swiftly raised his hand and used the next Ninjutsu.
Sizzle, sizzle, sizzle!
A loud and piercing thunderous sound erupted as a high-intensity electric current gathered swiftly in Mutsuki's hand, completing its transformation.
Boom, boom, boom!
Holding up Chidori, Mutsuki quickly moved to a distant large rock and punched a big hole into it.
"So fast, so powerful!" Kakashi thought as he watched Mutsuki's performance.
In terms of performance, False Darkness was much stronger, with a wider range and greater power sweeping over a large area. However, it was evident that False Darkness and Chidori were not the same type of Ninjutsu. Comparing their attack ranges would be unfair to Chidori, as Chidori was faster.
Kakashi believed that both False Darkness and Chidori were powerful Lightning Release Ninjutsu. False Darkness was suitable for long-range crowd control and wide-area attacks, while Chidori was for swift assaults and dashes.
Given his current fighting style, Chidori was more suitable for him, and it coincided with a Lightning Release Ninjutsu he had been considering.
"This Lightning Release, which one do you want to learn?" Mutsuki asked.
"The first one," Kakashi answered without hesitation.
Although Chidori suited his fighting style, he already possessed the sharp Hatake swordsmanship. What he lacked was a long-range, high-power Ninjutsu.
"But before we begin, I have to ask you a question," Mutsuki said with a smile.
"When I teach you Ninjutsu, what am I to you?"
"Instructor, sensei," Kakashi replied.
"Then what should you call me?"
Kakashi understood Mutsuki's intention. He wanted Kakashi to address him as sensei, just like Guy and Obito did.
"What a strange Ninja," Kakashi thought to himself. He felt that Mutsuki was indeed a bit odd, almost unlike a Ninja, or more precisely, unlike the present-day Ninja.
However, since Mutsuki was willing to teach him advanced Lightning Release Ninjutsu, Kakashi saw no problem in calling Mutsuki sensei. Teaching something and just leading a team to complete missions were different matters.
"Yumi-sensei," Kakashi calmly addressed.
[Establish a mentor-disciple relationship with Hatake Kakashi]
The system prompt immediately appeared, and Mutsuki decisively selected yes. As a promising disciple who came knocking on his door, he had to accept.
[Relationship established successfully, current trust level: one. Disciple Kakashi unlocked "Return the Disciple's Learning" and "Return the Mentor's Teaching"]
Looking at the trust level one, Mutsuki thought to himself that Kakashi really wasn't easy to persuade. He was already a fan of White Fang, yet he still wasn't willing to give a little more trust.
Mutsuki wasn't too surprised either. After all, he and Kakashi had only met yesterday. With Kakashi's current personality, it was difficult to establish trust in a short period.
Mutsuki glanced at Kakashi's latest status panel.
[Name: Hatake Kakashi]
[Chakra: 3300]
[Potential: S]
[Skills: Hatake Swordsmanship (Proficient), Lightning Attribute Chakra Nature Transformation (Proficient)…]
Kakashi's Chakra growth wasn't ideal. In nearly eight months, it had only increased by about eight hundred points.
Kakashi's potential as an S-rank without bloodline bonuses is of high value.
Regarding skills, because Kakashi's skills hadn't been upgraded during the appraisal, it's difficult to judge the progress in Ninjutsu.
However, Mutsuki feels that Kakashi's current skill values are average. Although he has some Proficient-level skills like Hatake Swordsmanship and Earth-Style Wall, they are just at the Proficient level, and the proficiency level isn't very high.
Mutsuki feels it might be because Kakashi hasn't yet emerged from the shadow of the White Fang suicide incident and is still in a transitional phase, so the data is a bit lacking.
While it's unfortunate for Kakashi himself, it's just right for Mutsuki, as any untapped potential Kakashi has will be a reward for Mutsuki after taking him as a disciple.
[Detected four disciples with potential of S-rank or above. System activates: System Store, Reward for Teaching Skill Enhancement Scroll]
[System Store: Selling some obtained physical rewards]
Mutsuki first opened the system store to take a look.
Inside, there were only three types of items for sale: Shuriken, Kunai, and Training Elixirs.
Furthermore, what pleased him was that the system store didn't require a special system currency; Land of Fire's money sufficed. However, aside from the Training Elixirs, Mutsuki wasn't planning to buy Kunai and Shuriken because the ones in the system were priced the same as those outside.
The Training Elixirs weren't particularly expensive, costing ten thousand Ryo each. Mutsuki felt that this price was reasonable considering the effects of the elixir. If he were to sell them, they would definitely be popular.
After all, these elixirs could eliminate fatigue and hidden injuries in the body, and Mutsuki had personally tested their powerful effects.
The opening of the system store relieved Mutsuki's urgent need. Previously, Guy gave twenty elixirs through training tasks, and after such a long time, they had almost been used up, leaving only a few for research purposes.
Next, Mutsuki used the Skill Enhancement Scroll, feeling somewhat excited about what new effects teaching skill enhancement would bring.
[Teaching: The knowledge you impart is easily remembered and understood. Diligent students will mentally rehearse the related content they learn.]
Looking at the latest description of the skill, Mutsuki felt it was a bit abstract. However, based on his experience with enhancing the Identification Jutsu, he expected the effects to be stronger.
Then, Mutsuki started teaching Kakashi.
"The Lightning Release: False Darkness's power is immense and its speed is fast, but one needs to be cautious of Chakra consumption; this Ninjutsu requires a lot of Chakra."
'I suspects that Kakuzu also has a high Chakra capacity, considering the Chakra required for techniques like False Darkness, Intelligent Hard Work, and Pressure Damage. Upon careful consideration, given the nature of Earth Grudge Fear, Kakuzu's Chakra might not belong to one person but rather to five.'
[You taught your disciple Lightning Release: False Darkness and gained the Ninjutsu Lightning Release: Purple Electricity.]
Perhaps due to Kakashi's personality and trust level, there were no setbacks despite it being his first time teaching Ninjutsu. After organizing the new Lightning Release memories in his mind, Mutsuki felt that this reward was quite good.
Because Purple Electricity can be considered an upgraded version of Raikiri. It required no hand seals to perform and possessed great power.
Mutsuki planned to teach Kakashi Purple Electricity after he learns False Darkness. While teaching Kakashi Purple Electricity won't trigger the student return effect, it will greatly enhance Kakashi's strength and shorten the time needed for advancement rewards.
