Mokgetsu taught Thunder Flash · Divine Speed to Kakashi, then taught Bursting Fist and Water Instant Body Jutsu to Nohara Rin.
Nohara Rin's chakra control ability is excellent, giving her a unique advantage in cultivating the Bursting Fist.
If she can learn these two skills well, Nohara Rin's combat ability will increase significantly.
The Bursting Fist can be considered an upgraded version of Monster Strength Power, more powerful and with more effects, while mastery of the Water Instant Body can greatly enhance Nohara Rin's mobility.
For now, Mokgetsu has not taught Great Flame Ring: Flame Emperor to Obito and Shisui, intending to teach them after they finish their current Fire Release training.
In fact, the power of Great Flame Ring: Flame Emperor is not as great as Mokgetsu's self-created Fire Dragon Dance, since Fire Dragon Dance is considered a Secret Technique Level Fire Release developed by Mokgetsu by integrating many Master Level Fire Release experiences. However, Fire Dragon Dance's requirements are too high, so learning Great Flame Ring: Flame Emperor can be a transition.
"Lord Habu, please come with me to the Hokage Building, the Third Lord is looking for you." The Anbu suddenly arrived as Mokgetsu was about to have dinner.
Mokgetsu didn't say much, nodded, and followed the Anbu to the Hokage Building.
"Being called at this time, it should not be a matter related to the Ninja Academy." On the way, Mokgetsu pondered the purpose of Sarutobi Hiruzen.
Even for a Hokage, it should be after work hours at this point. Thus, Sarutobi Hiruzen is currently working overtime, and matters related to the Ninja Academy should not require his overtime attendance.
"Is it war..." Mokgetsu thought of a possibility.
In his position as a teacher at the Ninja School, unless Konoha is at the end of its rope, they wouldn't send a teacher like him to the battlefield.
But Mokgetsu is different. Even though he's hidden many things, Mokgetsu's apparent strength surpasses most of Konoha's ninjas, fully qualifying him as a strong person.
As a strong person, Mokgetsu certainly cannot enjoy the same treatment as an ordinary Ninja School teacher, as the role a strong person plays in war is worlds apart from that of an ordinary Chunin.
If it weren't for Mokgetsu displaying extraordinary teaching abilities, he would've already been sent to the battlefield.
Knock.
Mokgetsu knocked on the wooden door of the Hokage Office.
"Come in." Sarutobi Hiruzen's voice came from within the office.
Mokgetsu pushed open the wooden door and entered the Hokage Office, while the Anbu stood guard outside, without entering with Mokgetsu.
As Mokgetsu entered the office, he saw Sarutobi Hiruzen with his hand pressed against his forehead, looking somewhat tired.
"Third Lord." Mokgetsu greeted Sarutobi Hiruzen with respect.
Sarutobi Hiruzen nodded slightly in response and then said in a deep voice:
"Mokgetsu, the village is under a lot of pressure now. The Three Great Ninja Villages of Hidden Mist, Hidden Rock, and Hidden Cloud are eyeing Konoha, and the Hidden Mist Village has even invaded the mainland of the Land of Fire, creating havoc on the east coast of the Land of Fire."
In the afternoon, Sarutobi Hiruzen held a high-level meeting with other top Konoha officials, who unanimously agreed to prioritize dealing with the Hidden Mist invading the mainland of the Land of Fire, and a strong response was necessary.
Hearing Sarutobi Hiruzen's words, Mokgetsu came to a realization.
"If the village needs me, I can head to the battlefield to provide support immediately." Mokgetsu said with determination.
With Mokgetsu's current strength, if he can't win on the battlefield, he can at least escape, so he doesn't have to worry too much about safety.
Additionally, Mokgetsu wanted to use the battlefield to train his disciples. With the ninja world becoming increasingly chaotic, and Uchiha Madara possibly making a move at any time, he must do everything possible to improve his disciples' strength.
Sarutobi Hiruzen's face revealed a satisfied smile, Mokgetsu's Will of Fire was very strong.
"With your teaching abilities, Mokgetsu, you should be nurturing the next generation in the rear, but the village needs your fighting power at this moment. We must expel the enemy as quickly as possible." Sarutobi Hiruzen said seriously.
Due to the Hidden Cloud's Jinchuriki replacement, the loss of a top-level combat power, the high-level meeting decided to transfer Orochimaru from the Land of Hot Water battlefield back to the Land of Fire to deal with the Hidden Mist.
To make up for Orochimaru's power, the high-level meeting sent Namikaze Minato to the Land of Hot Water to guard against surprise attacks from the AB Combo.
The Hidden Mist is still one of the Five Great Ninja Villages, Sarutobi Hiruzen thought that just Orochimaru wasn't enough. After sending Ino-Shika-Cho and a group of Jonin Hyuga, he thought of Mokgetsu again.
Mokgetsu is proficient in five chakra attributes and has mastered Ice Release. He has even learned the Flying Thunder God Jutsu, and has defeated the Hidden Sand Hero Pakura in battle.
After careful consideration, Sarutobi Hiruzen realized Mokgetsu's strength has surpassed most ninjas in the ninja world, except that he's not famous yet.
Danzo first suggested sending Mokgetsu to the battlefield, which Sarutobi Hiruzen initially opposed.
Because Konoha has few, but not no strong people like Mokgetsu, but Mokgetsu's level of teaching ability is unique in the ninja world.
As the one who discovered Mokgetsu, Sarutobi Hiruzen knew Mokgetsu's teaching abilities inside out.
He himself taught Asuma ninjutsu, but the results were nowhere near as good as Mokgetsu's.
However, after Danzo analyzed the pros and cons, and considering the pressure from the Daimyo of the Land of Fire, Sarutobi Hiruzen ultimately decided after much deliberation to let Mokgetsu join in expelling the Hidden Mist from the battlefield.
Due to the Flying Thunder God, Mokgetsu's ability to preserve his life is strong, and even in defeat, he can escape.
After receiving his mission, Mokgetsu left the Hokage Building and assembled his disciples, except for Might Guy, to inform them of the plan to participate in the war.
Might Guy was not informed because Sarutobi Hiruzen had given Mokgetsu a list of support units, and Might Guy's team was included, so Mokgetsu didn't specifically notify him.
Mokgetsu informed Kakashi and the others because Kakashi's team was not included, and Mokgetsu needed to take them with him.
"The battlefield..." Shisui's eyes flickered; among Mokgetsu's disciples, only he hadn't been on a battlefield before.
Obito had a nonchalant expression; he already had a lot of battlefield combat experience, the first time being an unexpected incident during training, where they participated in a major battlefield brawl, followed by numerous battlefield missions led by Namikaze Minato.
"Since the Third has given me some important tasks, on the battlefield, I won't be able to guide you in battle as I usually do," Mokgetsu reminded them.
Although he would certainly send out Shadow Clones to protect his disciples, Mokgetsu didn't want them to know this, as it would prevent them from facing truly desperate situations.
Obito's expression changed slightly; without Sage Mokgetsu's protection, the danger level would be greatly increased.
Most of his experience came with someone to back him up—sometimes it was Mokgetsu, other times it was Namikaze Minato.
"Teacher Mokgetsu, I think there should be a vice-captain. If you're not around, the vice-captain can command," Kakashi thought and suggested.
Although Obito rarely screwed up at crucial moments, Kakashi didn't want to take any chances. If he became vice-captain, he could rightfully command Obito.
"Alright, the four of you can vote to decide." Mokgetsu nodded.
Ultimately, Kakashi won the title of vice-captain by a margin of three votes, with everyone but Obito, who voted for Nohara Rin, voting for Kakashi.
