Naruto: Starting by Teaching Tsunade Modernization

The next day.

Haruki and Kakashi returned to the samurai dojo.

However, unlike usual, there was an additional person in the dojo, Mifune.

They had a good conversation the previous day.

One reason was Haruki's status, which made Mifune not dare to do anything rash.

The other reason, of course, was Mifune's interest in the Niten Ichi-ryu, but he didn't believe Haruki was Kakashi's teacher.

Mainly because Haruki's fame as a medical ninja and one of the Twin Gems of Konoha was too intimidating.

So much so that he couldn't believe Haruki was a great swordmaster.

Perhaps the styles of a doctor and a samurai didn't match.

"Lord Mifune."

Kakashi greeted politely.

As the chief of the samurai in the Land of Iron, Mifune's status was basically on par with that of a Kage in a ninja village.

It was quite fitting for Kakashi to address him this way.

"Please."

Mifune returned the courtesy.

No, it should be said that this courtesy was a bit too high for Kakashi.

Even the surrounding crowd was in an uproar, speculating about Kakashi's teacher.

It was impossible for a four-year-old child to earn Mifune's respect like this. The only explanation was that his teacher was extremely powerful.

At this time, Kakashi didn't have the fame of the Copy Ninja or the First Technician of Konoha as in the original story.

It was natural for the people in the Land of Iron to make such speculations.

The two stepped into the arena.

Kakashi remembered what Haruki had told him.

Mifune wouldn't use his full strength against him. It was more likely to be a sparring session with a guiding purpose.

By the way, he could get a glimpse of the Niten Ichi-ryu Kendo.

But Kakashi had to use all his strength.

He tightly gripped his twin swords, and blue Chakra quickly covered them.

Just then, he heard a metallic tremor.

It was as if a blade was being drawn from its sheath.

Kakashi instinctively looked up, and all he saw was a flash of sword light.

So fast!

That was his only thought.

"Good reaction."

Instead of belittling him, Mifune praised him, saying, "My Iai Beheading is such that there are few people in the entire Land of Iron, no, in the entire ninja world who can withstand it."

Kakashi nodded silently.

He had heard from Haruki that Mifune had once fought Hanzo during the Second Great Ninja World War. Although he had lost, it was still worthy of praise.

After all, the Sannin of Konoha combined hadn't been able to defeat Hanzo.

"Continue."

Mifune took a few steps back without sheathing his samurai sword.

His Iaido, also known as the Way of Drawing the Sword, was most terrifying for its extremely high speed and astonishing explosive power.

And the most powerful move was the Iai Beheading just now when he drew his sword.

Kakashi wasn't discouraged. He looked serious, suddenly exerted force with the muscles in his legs, and charged forward with his twin swords.

Two streaks of sword light were left in the air.

Mifune's eyes lit up slightly.

This was indeed a brand-new Kendo style, not a modified one.

He casually swung his sword.

Simple yet effective.

The sword brushed past the two streaks of sword light and accurately struck Kakashi's right wrist.

Kakashi immediately felt a numbness in his wrist and lost his strength. The wooden sword slipped out of his hand.

In a life-and-death battle, his right hand would have been directly severed.

Mifune showed a kind smile.

Watching Kakashi run to pick up the wooden sword, one couldn't help but sigh that the geniuses in Konoha Village just kept emerging.

During the Second Great Ninja War he took part in, there were Sakumo Hatake, the Sannin, and Minato Namikaze of the younger generation.

As for the Land of Iron, the talent gap was clearly visible.

If Haruki knew what he was thinking, he would definitely tell him that it wasn't just during the Second Great Ninja War. By the era of Itachi Uchiha and Naruto Uzumaki, there were not only many geniuses, but each of them was incredibly powerful.

However, what Hiruzen Sarutobi and Tanzo Shimura liked to do most was to stifle the growth of geniuses.

After Kakashi retrieved the wooden sword, he launched another attack on Mifune.

He raised his long sword and took up an upper - level attack stance.

Using Lightning Release for acceleration, a dazzling sword aura suddenly appeared in front of his body.

Mifune shook his head slightly.

Kakashi's current strength rendered his sword light too illusory.

In other words, it was overly flashy.

He swung his samurai sword through the air, creating an arc - shaped sword aura. With a turn, he sent Kakashi flying directly.

Such scenes repeated continuously within three hours.

Until Kakashi lost his strength completely.

Haruki stepped forward, patted him on the shoulder, and said smilingly, "Come again tomorrow."

Kakashi immediately stopped struggling and slumped to the ground, gasping for breath.

Haruki greeted Mifune and led Kakashi away.

And Mifune didn't refuse.

Musashi Miyamoto's Niten Ichi - ryu couldn't be mastered in just three hours.

He had already sensed the awesomeness of this school, and even had the idea of stealing the skills.

If he could gain some insights, perhaps his strength could be improved to a new level.

The on - looking crowd immediately burst into cheers.

Mifune frowned slightly and couldn't help scolding, "What are you cheering for? If you can last three hours under my sword, then come and cheer!"

The dojo immediately fell into silence.

"A bunch of troublesome guys. You're not even a match for a four - year - old kid. Why aren't you going to train?"

After Mifune finished speaking, the people in front of him scattered like birds and beasts.

Haruki and Kakashi returned to the inn without eating or resting.

He first asked Kakashi how he felt, and then explained Mifune's Iaido.

Since attaining the Mujikuken state of kendo, all kendo styles had no secrets in front of him.

It was probably what is meant by 'mastering one method leads to mastering all methods'.

One day, Mifune keenly noticed Kakashi's progress. Although it was only a little, it was enough to surprise him.

These geniuses really left no way out for others.

He boasted of being a genius in Iaido, but it was still difficult for him to achieve what Kakashi had done.

But obviously, his surprise came too early.

A month later, Mifune looked at Kakashi and began to doubt his life.

Sometimes, the gap between people was even wider than that between humans and dogs.

"Kakashi, you don't need to compete with me anymore."

Mifune stepped back to keep a distance, shook his head, and said, "In terms of swordsmanship alone, there aren't many people who can match you now. What you lack is chakra and age."

There was another reason for him to say this. He had basically grasped the Niten Ichi - ryu.

After all, he was at least a master of kendo, and Kakashi had demonstrated it to him for a month.

Hearing this, Kakashi was stunned for a moment and looked up at Mifune.

His expression didn't seem to be a pretense.

Indeed, he himself felt that the pressure exerted by Mifune's swordsmanship was gradually decreasing.

Of course, this only referred to swordsmanship.

"Lord Mifune, I still have a sword move," Kakashi said after taking a deep breath. He had the Chakra necklace given by Haruki and could barely perform it.

"I'd like to experience your Iai Beheading once more."

"Oh?"

Mifune became interested, mainly because Kakashi sounded so confident.

How could he still be so confident after witnessing my Iai Beheading?

"Go ahead."

Mifune sheathed his wooden sword and placed his right hand on the hilt. He fell into an extremely dangerous state.

Kakashi tightly grasped his wooden sword.

Chakra gushed out, and the necklace on his chest moved without wind.

Suddenly, a Ni - o like a ghost emerged behind him.

Mifune couldn't help but widen his eyes.

What the hell kind of swordsmanship is this?

This is way too surreal, isn't it?

In the moment he was muttering to himself, his vision went dark for half a second and then cleared up again. In his field of vision, a soaring sword light, like a pillar of light, descended upon him.
