"Currently, I mainly focus on these two." Kakashi nodded and said.
Now, in battle, Kakashi primarily relies on swordsmanship and Lightning Release, with Earth Release playing a supportive role.
"I'm not too good with short blades, but I can teach you Lightning Release first." Mokgetsu thought for a moment and said.
"Come with me, and see which ninjutsu you want to learn."
Mokgetsu led Kakashi into the depths of the wooded training ground.
"Lightning Release: Pseudo-Darkness!" Mokgetsu quickly formed hand seals and then spat out a giant lightning spear, instantly piercing through and knocking down all the trees within twenty meters in front of him, leaving charred marks at the points of breakage.
"What a powerful Lightning Release ninjutsu!" Kakashi could not help but praise as he gazed at the fallen trees, elevating his estimation of Mokgetsu even further.
Based on his current observation, Kakashi considered Mokgetsu to be an elite among the Jonin, excelling in both Taijutsu and ninjutsu.
"Lightning Release: Chidori!" Mokgetsu didn't rest and quickly raised his hand to use the next ninjutsu.
Zzzzz!!
A loud, jarring electric sound erupted as a high-intensity current quickly formed and changed shape in Mokgetsu's hand.
Rumble!!
Mokgetsu, holding the Chidori, swiftly moved to a large rock in the distance and punched a big hole into it.
"Such speed and penetration power!" Kakashi thought as he observed Mokgetsu's performance.
In terms of display, Pseudo-Darkness had greater power and covered a larger area, sweeping across a wide expanse. However, comparing Pseudo-Darkness to Chidori in terms of attack range was unfair to Chidori because Chidori was much faster.
Kakashi believed that Pseudo-Darkness and Chidori each had their strengths, both being very powerful Lightning Release ninjutsu. Pseudo-Darkness was suitable for mid- to long-range wide attacks, while Chidori excelled in quick assault charges.
Considering his current fighting style, Chidori suited him better, and it aligned with a hypothetical Lightning Release ninjutsu he envisioned.
"Which of these two Lightning Releases do you want to learn?" Mokgetsu asked.
"The first one." Kakashi said without hesitation.
Although Chidori suited his fighting style, he already had the fierce Hatake Blade Technique, so he needed a long-range high-power ninjutsu instead.
"But before you learn it, I need to ask you a question first." Mokgetsu said with a smile.
"I'm teaching you ninjutsu, what am I to you?"
"A mentor." Kakashi replied.
"Then what should you call me?"
Kakashi understood what Mokgetsu meant, wanting him to address him as a teacher like Might Guy and Obito.
"Such a strange ninja." Kakashi thought to himself, feeling that Mokgetsu was quite odd, almost unsuited to be a ninja, or rather unlike current ninjas.
However, since Mokgetsu was willing to teach him advanced Lightning Release ninjutsu, Kakashi felt there was no problem calling Mokgetsu teacher, as teaching differed from merely leading a team on missions.
"Teacher Mokgetsu." Kakashi calmly addressed.
[Would you like to establish a master-apprentice relationship with Hatake Kakashi?]
The system window immediately appeared, and Mokgetsu unhesitatingly chose yes, eager to accept this S-potential disciple brought to him.
[Relationship established successfully, current trust level one, disciple Kakashi unlocked "Apprentice Cultivation Returning Master," "Teaching Return."]
Seeing the trust level of one, Mokgetsu thought to himself that Kakashi was really hard to fool. Although he was a fan of White Fang, he still wouldn't give a little more trust.
Mokgetsu wasn't too surprised, as he and Kakashi had only met yesterday. With Kakashi's current personality, it was hard to build trust quickly.
Mokgetsu used the Identification Jutsu to glance at Kakashi's latest status.
[Name: Hatake Kakashi]
[Chakra: 3300]
[Potential: S]
[Skills: Hatake Blade Technique (Proficient), Lightning Attribute Chakra Nature Changes (Proficient) ...]
Kakashi's chakra growth wasn't ideal; almost eight months had passed with only about an increase of eight hundred chakra points.
It's worth noting that Kakashi, with S-class potential without bloodline enhancement, had high value.
Skill-wise, as the skills hadn't been upgraded the last time Mokgetsu used Identification Jutsu on Kakashi, it was hard to assess progress in ninjutsu.
However, Mokgetsu felt Kakashi's skill values were quite average now. Although there were some proficient-level skills, like the Hatake Blade Technique and Earth Flow Wall, they were just at the proficient level with low proficiency.
Mokgetsu thought it might be because Kakashi hadn't moved past the shadow of White Fang's suicide event and was in a laidback state, leaving the data somewhat poor.
It was a pity for Kakashi himself, but for Mokgetsu, it was just right. After all, Kakashi's untapped potential would be Mokgetsu's reward as a master.
[Detected four disciples with S level or above potential, unlocking System Mall, awarding "Skill Teaching Enhancement Scroll."]
[System Mall: Offers some previously obtained physical rewards for sale.]
Mokgetsu first opened the System Mall for a look.
Inside, only three items were for sale: Shuriken, Kunai, and the Training Elixir.
Moreover, to his satisfaction, the System Mall didn't require special system currency and could use money from the Land of Fire. However, apart from the Training Elixir, Mokgetsu didn't plan to buy Kunai and Shuriken, as their prices were the same as outside.
Conversely, the Training Elixir wasn't particularly expensive at ten thousand ryo each, which, compared to its effects, was already cheap; if sold, it would definitely be a hit.
After all, it was a secret medicine capable of eliminating fatigue and hidden injuries, with Mokgetsu personally testing its powerful effect.
The opening of the System Mall alleviated Mokgetsu's urgent needs. The Training Elixirs obtained from Might Guy's training mission, totaling twenty, were almost consumed over the months, leaving a few samples for research.
Then, Mokgetsu used the skill enhancement scroll, anticipating what new effects the strengthened teaching skills might have.
[Mentor: The knowledge you impart is easily remembered and understood; diligent disciples will pre-enact related content in their minds.]
Mokgetsu looked at the latest skill description, feeling it a bit abstract, but based on the experience from Identification Jutsu strengthening, it would certainly enhance the effect.
"The lightning spear from Pseudo-Darkness is powerful and fast, but you need to be mindful of chakra consumption; it's very chakra-intensive." Mokgetsu prepared to start teaching.
He suspected that Kakuzu had high chakra as well, given that the jutsus like Pseudo-Darkness, Headache, and Pressure Harm required substantial chakra.
On deeper thought, with the characteristics of Earth Grudge Fear, it's likely that Kakuzu's chakra wasn't just one person's capacity but that of five people.
[You have instructed your disciple in Lightning Release: Pseudo-Darkness and obtained the ninjutsu Lightning Release: Purple Lightning]
Possibly due to Kakashi's personality and trust issue, although it was the first time teaching ninjutsu, there was no critical hit.
After sorting through the newly emerged Lightning Release memory in his mind, Mokgetsu felt the reward was decent.
Because Purple Lightning could indeed be considered an upgraded version of the Lightning Blade, it could be performed without forming seals and was very powerful.
Mokgetsu planned to pass Purple Lightning onto Kakashi once he mastered Pseudo-Darkness. Teaching Purple Lightning to Kakashi might not trigger the teaching return effect, but it would significantly help Kakashi's growth in strength, shortening the time to increase rewards.
