Mifune still had time to make sarcastic remarks in the face of such an offensive, which proved his ease.
He held his breath and concentrated, and an astonishing momentum quickly released from his body.
A strange hissing sound rang out in the space between him and Kakashi.
This was Mifune's samurai sword unsheathing at an extraordinary speed, cleaving through the invisible air and colliding with Kakashi's sword light.
It was like a white dragon having its head chopped off.
In front of Mifune, the imposing light column suddenly stopped its forward momentum.
Because the subsequent Chakra could no longer be supplied.
Kakashi's sword-style dissipated due to the lack of Chakra support.
From the perspective of onlookers, it was Mifune casually swinging his sword to cut off Kakashi's sword light.
But accompanied by a series of cracking sounds.
The wooden boards made of special materials under Mifune's feet suddenly cracked, and countless wood chips and fragments spurted out.
He took a deep breath and slowly retracted his sword.
He remembered something.
When he returned to the Land of Iron, the astonishing sword aura he saw at sea.
It seemed to be of the same origin as Kakashi's.
Although it was much weaker, there was no doubt that it gave the same feeling.
"You're good."
Mifune looked at Kakashi, who was supporting his body with a wooden sword, and gave his highest praise.
"Thank you, Lord Mifune."
Kakashi managed to return the greeting.
In this month, Mifune was undoubtedly his teacher, teaching him whole - heartedly.
Mifune understood [Niten Ichi - ryu], and wasn't he also learning [Iaido]?
Haruki quickly stepped forward and used [Healing Jutsu] to restore Kakashi's body.
"Kakashi, I want to ask you, a month ago, did your teacher use the same sword style at sea?"
"Huh? How do you know?"
Kakashi couldn't help being a little surprised when he heard this.
When Haruki demonstrated [Niten Ichi - ryu], Mifune couldn't have been there.
"The sword aura remained condensed. I was fortunate enough to witness its lingering power."
A look of yearning appeared on Mifune's face. He sighed and said, "Your teacher should have reached the highest realm of [Kendo], so he can do such a thing."
Kakashi subconsciously glanced at Haruki, but Mifune didn't notice.
He snapped out of it and continued to ask:
"I wonder who your teacher is exactly? It's really strange that I know nothing about this person who can be called a great swordmaster. Could it be your father, Sakumo Hatake, the Legend of the White Fang?"
"No."
Kakashi quickly shook his head. Just as he hesitated whether to say Haruki's name, he heard Haruki speak.
"His teacher is indifferent to fame and fortune. It's normal that Chief Mifune doesn't know him."
If it were just Mifune, it wouldn't matter to tell him.
But there were too many people in the dojo. In a few days, everyone would know, and it would be a troublesome thing.
Haruki decided to keep it a secret.
"What a pity."
Mifune wasn't surprised either. He really agreed with Haruki's explanation.
After all, with such swordsmanship, a bit of promotion could make one well - known worldwide.
Then, Mifune invited Haruki and others to have a meal in the palace of the Land of Iron.
Although he and Kakashi didn't have the name of a master - apprentice relationship, they had the reality of it.
Knowing that they would leave soon, Haruki felt a bit reluctant to part with Kakashi.
But if Kakashi could help promote Iaido in the future, it would be worth the one - month of teaching.
No, with Kakashi's talent, he was bound to shine in the ninja world.
Haruki called Tsunade, Kakuzu and the others to go to the Daimyo's mansion to have a sumptuous free meal.
As Mifune had guessed, Kakashi's swordsmanship had improved significantly.
There was no need to stay here anymore.
However, Haruki didn't expect that he would receive a letter from Mikoto Uchiha the next day.
There were three things in it.
The first thing was that there was a traitor in the Uchiha Clan.
He was originally from the Kage - protecting Faction and was naturally close to the Hokage lineage.
He was found to be in contact with Tanzo Shimura last week.
Mikoto didn't show any mercy and immediately captured him. After interrogating him with the Mangekyo Sharingan, she got an astonishing piece of news.
Tanzo wanted him to assassinate Haruki.
The reason was that previously, the elite members of Root had encountered Kakuzu, and none of them made it out alive.
In a fit of rage, Tanzo set his sights on the Uchiha Clan.
Since there was a rumor that the Uchiha were invincible in one - on - one battles and they had the Sharingan, Tanzo thought they couldn't even defeat Kakuzu.
But unfortunately, the Uchiha had been purged by Mikoto.
After reading this piece of news, Haruki finally understood why Tanzo hadn't sent anyone over for a whole month. It turned out that their plan failed before it even started.
The second thing was a continuation of the first one.
Mikoto's decisive actions made Tanzo Shimura suspicious.
Coupled with the change in the Uchiha's attitude during this period, it also made Hiruzen Sarutobi have doubts.
So the Anbu and Root began to be more vigilant and keep a closer eye on the Uchiha.
The third thing was Mikoto's own feeling.
Only once or twice.
She noticed someone spying on her secretly.
But she couldn't find his figure.
The high level of concealment made Mikoto suspicious, so she wasn't quite sure.
But Haruki knew who it was.
Madara Uchiha or rather, the White Zetsu and Black Zetsu.
Judging from the original story, they had been paying attention to the Uchiha Clan for a long time.
Although they had finally chosen Obito Uchiha, they must have also noticed the changes in Mikoto.
After thinking for a moment, Haruki picked up his pen and wrote a reply to Mikoto.
For the first thing, he told her not to stop them in the future. He actually wanted to see what other tricks Tanzo Shimura could come up with.
For the latter two things, he told her to be patient. Hiruzen Sarutobi and Tanzo Shimura wouldn't take action without conclusive evidence.
This chapter isn't over yet!
Similarly, Madara Uchiha and the Zetsu would also not take action until they were certain that Mikoto's eyes were the Mangekyo Sharingan.
A new day.
Haruki was ready to leave the Metropolis of the Land of Iron.
However, as soon as he opened the door, he saw Kakashi beating up Obito.
After a month of teaching from Mifune and him, Kakashi's current level far exceeded Obito's.
Although Obito also had Kakuzu as a teacher, the Ninjutsu that Kakuzu was good at couldn't be taught to him, nor would he teach him.
Actually, Obito's strength had also been greatly improved. He could at least be regarded as a genius in this session of the Ninja Academy.
"You lost."
Kakashi retracted his twin swords and said nonchalantly.
"Damn it!"
Obito looked extremely frustrated.
He most wanted to surpass Kakashi. But judging from the recent situation, instead of narrowing the gap with Kakashi, the gap was actually widening.
"Teacher."
Noticing Haruki beside him, Obito suddenly felt a bit wronged and said, "Why can't I learn swordsmanship?"
"Naturally, it's because there are other things you should learn."
Haruki thought for a moment. In fact, Obito's Chakra was far greater than that of his peers at present, and perhaps he already had the physical condition to awaken his Dojutsu.
"Alright, tomorrow, I'll help you improve your strength."
"Really?!"
Unexpectedly getting Haruki's promise, Obito immediately beamed with joy.
"Go and call Rin and the others over for dinner."
After sending Obito away, Haruki whispered a few words to Kakashi.
"…?"
Kakashi looked at Haruki in shock, doubting what he said.
"Just do as I say tomorrow."
Haruki patted his shoulder and smiled. "This is the inevitable path for Obito to become stronger."
