Minato's letter was quite concise, without anything too important, condensed into one line, "I'm going to the battlefield on a mission, please take care of Kushina's meals."
Of course, the actual content wasn't that straightforward; it would be more euphemistic, with some words of thanks.
Although Minato's letter didn't discuss anything particularly important, the fact that Minato was going to the battlefield held certain significance for Mokgetsu.
It might be that the probing attacks have ended and both sides of the war are officially engaging in battle now.
Although the Third Ninja World War might last about four or five years, it's not like all four years would be probing and the final year would suddenly reach a climax.
However, this doesn't have much to do with the current Mokgetsu. As long as it isn't something on the level of ten thousand Hidden Rock troops storming the border, as a Special Jonin with a specialty in teaching, he basically wouldn't be assigned to war missions to fight on the battlefield.
Being a teacher at the Ninja School has this benefit; unless it gets to the worst of times, it's not the teachers' turn to go to the battlefield.
After reading Minato's letter, Mokgetsu also began to sort out his own improvement plans for the upcoming days.
First is the soon-to-explode gold coins with Obito, as Obito's birthday is just twenty-one days away, and barring any unexpected incidents, it's another perfect-level skill.
After Might Guy's birthday ended, Mokgetsu directly asked Obito what birthday gift he wanted.
Obito usually boasts a lot, but when Mokgetsu really asked him, Obito could hardly say anything. In the end, he said anything from Mokgetsu was fine.
Obito's response was within Mokgetsu's expectations, not because Obito had a difficult personality, but because Mokgetsu was usually so good to them that Obito felt even more embarrassed to trouble Mokgetsu.
Mokgetsu asked the question even knowing the answer because he wanted to instill in Obito the mindset "Teacher Mokgetsu cares a lot about me and is very concerned about my birthday gift," to help trigger the final emotional explosion.
About ten days after Obito's birthday, there's an opportunity to earn exam rewards.
Indeed, during the internship period, students must return to school to take exams. This is a rule set by Mokgetsu.
This is the last regular exam that Obito and the others can take. The next final exam is the graduation exam, testing only the Three-Body Jutsu.
Apart from the fixed items like birthday gold explosions and exams, Mokgetsu's improvement plan mainly focuses on the training plans for his students. After all, as his students improve, so does he.
Obito's Breathing Technique has already advanced to a certain extent, and Mokgetsu plans to conduct a new Breathing Technique special training for him, aiming for the next realm, Constant State.
Constant State means maintaining Full Concentration Breathing twenty-four hours a day, even during sleep.
Of course, this Full Concentration Breathing is not the ultimate form but a relatively concentrated one, equivalent to a slightly weakened Full Concentration Breathing. Completing this stage of cultivation would result in a qualitative change in physical capability and significantly enhance the Breathing Technique's effectiveness.
Besides advancing the Breathing Technique, Mokgetsu is also figuring out ways to enable Obito to awaken the Sharingan.
The benefits of awakening the Sharingan are numerous, with strong dynamic vision, amplified genjutsu, and even enhanced chakra.
This is why the Uchiha Clan has so many Jonin; as long as they awaken the Sharingan and don't die, they naturally develop into Jonin.
Although last time Shisui was able to awaken his eyes on his birthday, Mokgetsu doesn't think Obito can awaken his eyes just because of his birthday.
Shisui's trust level reached three much later than Obito and Might Guy, but he was the first to reach level four, mainly because the emotional explosion that night was too great, causing the Sharingan to manifest.
Obito might be the most trusted disciple among them, but the likelihood of an emotional burst isn't as high.
Mokgetsu's current idea is to give Obito and the others more challenging tasks next time they encounter enemies, to stimulate them.
For Might Guy, the focus should still be on the Eight Gates, aiming first to reach the level of opening three gates.
Shisui can join Obito in training for the Constant State of Breath of Flame and then work on enhancing the Sharingan and boosting Haki.
As for Kakashi, the priority is to straighten him out a bit; his main focus should be on cultivating Breath of Thunder with a secondary focus on Armament Aura.
After organizing what needed to be done next, Mokgetsu headed to the Southern Border Forest.
Upon arriving, Mokgetsu found everything as usual; all the students were cultivating.
Seeing all five students present and in neat order, Mokgetsu was a bit surprised. Though Obito wasn't exactly lazy, he didn't have the enthusiasm for cultivation like Might Guy; during breaks, he really took them to rest.
"It looks like everyone is quite motivated today," Mokgetsu smiled and complimented.
Might Guy flashed a big thumbs-up with his gleaming white teeth.
Kakashi continued performing various Breathing Technique movements in silence, offering no comment.
Obito forced a smile, showing agreement.
Seeing his students' high enthusiasm for training, Mokgetsu also promptly started today's lessons.
Since Might Guy and Obito have yet to master Yin Release Nature Transformation, the formal training for Armament Aura hasn't started.
Currently, Obito's proficiency in Yin Release Nature Transformation has reached about seventy points, which is a promising sign of success, while Might Guy's is much lower, only at around twenty points, needing considerably more effort.
Through persistent effort, Kakashi finally broke through ten points in proficiency of Breath of Thunder, currently able to use breathing to enhance physical capacity, though the boost is moderate; it's a breakthrough from nothing to something.
Shisui's progress in Armament Aura has also shown some results, achieving twelve points in proficiency after twenty days of hard training, gradually developing some feel for it.
Meanwhile, Nohara Rin's chakra control improved by leaps and bounds, reaching the introductory level of Monster Strength Power, further enhancing explosiveness, while learning the Mystical Palm Jutsu has also entered the correct path.
To further enhance Nohara Rin's abilities, Mokgetsu is attempting to develop a new Breathing Technique to teach her.
He has mastered three major Breathing Techniques, one of which has even reached perfect level, showing he has quite a grasp of Breathing Techniques.
Though developing a stronger one may be difficult, he can certainly develop one of comparable level.
However, his knowledge of Medical Ninjutsu isn't sufficient; it's impossible to develop a Breath of Medicine. But with over seven thousand proficiency in Water Attribute Chakra Nature Changes, he can develop a Breath of Water for Nohara Rin, whose innate attribute luckily is water.
Having mastered Breath of Water and Monster Strength, Nohara Rin shouldn't be easily captured during the war.
When training ended, Obito couldn't wait to rush over to Nohara Rin to share his experiences.
"Rin, you absolutely can't imagine how exciting our mission experiences are. Two C-Class Missions, one turned into an A-level, and one turned into a B-level. Each time we encountered formidable ninja foes," Obito said excitedly, clearly holding it in for too long.
Obito then vividly described the scenes where he quickly defeated powerful enemies.
Nohara Rin smiled and applauded in approval, giving him face.
"Truly exciting, you three are so amazing, almost like the stories the teachers tell of their mission experiences."
"Hehe, it's thanks to Teacher Mokgetsu's competence, other interns seem to only take odd jobs around the village," Obito said, looking at Nohara Rin's smiling face with satisfaction, feeling it was all worth it.
Kakashi, who was about to leave after concluding the training, paused upon hearing Obito and Nohara Rin's conversation, only leaving after Obito finished speaking.
If Obito was sneaking in personal matters, Kakashi would speak about the time Obito was careless and almost got injured. However, this time Obito mostly spoke truthfully.
