The last boss of the ninja world

"Oh? Haha, then I am your family too, right?"

Tsunade was amused by Musashi's unreasonable teasing, so she pretended to be an elder, stood opposite Musashi, and then straightened his messy collar.

"if you are willing to……"

Musashi blushed with embarrassment and turned his head away unnaturally.

But unexpectedly, he found Sarutobi Shinnosuke squatting on the ground, talking and laughing with a child about five or six years old.

"Brother, I miss you so much!"

The child spread his arms and asked Shinnosuke for a hug.

"You little brat," Shinnosuke stretched out his finger and pointed at the child's forehead: "Did you do something bad again and you want your brother to take the blame for you?"

"No!" The child quickly denied, then pouted, lowered his head and played with his fingers and said: "I have some ideas about the wind blade that my brother taught me last time."

"Do you have any clues?"

Shinnosuke was stunned for a moment, then smiled again.

This kid, if he has some eyebrows and still poses like this, then he probably has no eyebrows at all.

"Wind Blade?"

Musashi muttered softly and walked behind Shinnosuke.

"Brother Musashi!"

When the child saw Musashi, he left Shinnosuke behind, trotted to Musashi's feet, hugged Musashi's legs, and said coquettishly: "Long time no see, I miss you, brother Musashi."

know me?

Musashi knelt down, stretched out his fingers, and pinched the child's face that had not lost its baby fat.

Calling Shinnosuke my brother, I mentioned the Wind Blade before...

Is he Asuma Sarutobi?

Sarutobi Asuma passed away in Konoha 64 years ago. According to the Book of Masters, Sarutobi Asuma was 31 years old.

He was 64 years old in Konoha 31, that is, Asuma Sarutobi was born in Konoha 33, and this year is Konoha 39, so Asuma should be 6 years old!

The age matched and the conditions matched, Musashi recalled the plot in the novel where Sarutobi Asuma appeared, so he joked: "Did you get into trouble again?"

"Huh, what?" Asuma threw away Musashi's palm unhappily and shouted at Musashi and Shinnosuke: "I have grown up. Don't always think that I only get into trouble. I am good now."

Shinnosuke and Musashi looked at each other, and both of them were suddenly amused by Asuma's little adult appearance.

"If you laugh again, I will ignore you!"

Asuma crossed his waist. If he hadn't been thinking about his brother's Wind Blade, he would have turned around and left immediately.

"Okay, okay, our Asuma has grown up." Musashi patted Asuma's back comfortingly and asked: "What are you doing to see your brother today? You little guy, I don't believe you. I really missed your elder brother so I came to see him."

Asuma's little thought was exposed by Musashi, and Asuma stamped his feet anxiously. He seemed to retort, but he was afraid that his elder brother would not teach him the tricks of the Wind Blade because of this, so he had to hold his head and admit, "I encountered a problem when practicing the Wind Blade." A little bottleneck..."

"I won't tease you anymore, come and tell my brother where you encountered the problem."

The visit time was limited, so Shinnosuke stopped teasing Asuma, squatted in front of Asuma, and asked seriously.

Asuma's face was filled with joy, and he quickly broke away from Musashi's control, took out a note written in advance from his arms, and read: "[-]. How does the chakra that changes in wind attribute attach to the sharp blade. [-]. The skill of air control."

Musashi raised his head and glanced at it. He originally wanted to use [Real-time Translation] to find out the secret of [Wind Blade]. Who would have thought that there were no words on the note at all, but random graffiti that only children could recognize.

"Have you mastered the changes in chakra properties of the wind attribute?"

When Shinnosuke heard this, he suddenly grabbed Asuma's arm excitedly.

Only then did Musashi react, staring at Sarutobi Asuma with an incredulous expression.

He is only six years old,

He has actually mastered the changes in the nature of chakra!

"Yeah," Asuma nodded, took out a wooden kunai from the pocket ninja bag on his leg, and then closed his eyes.

The next second, a slender strip of light blue chakra spurted out from the tail of the wooden kunai.

Sure enough, it turned out to be wind-type chakra.

It's a pity that they quickly disappeared into the air and did not condense on the blade to increase the sharpness of the blade like in the original Naruto novel.

"Silly boy, try using this weapon."

Shinnosuke rubbed Asuma's head, took out a finger knife and handed it to Asuma.

Isn't this the chakra blade used by Asuma in the original work?

Musashi's heart trembled and he stared at the chakra blade carefully.

The Chakra Blade looks like nothing on the outside, but there is something different inside the blade.

It's a rune!

[Real-time translation] took effect, and a text suddenly appeared on the originally smooth surface of the blade: [Constrain Chakra and shape it].

Musashi is currently in contact with the materialization of chakra. He knows better than anyone how difficult it is to materialize chakra.

Without the aid of external objects, unless you use the power of the spiral to shape chakra like Namikaze Minato's Rasengan, it is really difficult to achieve the effect of [Wind Blade] with just your own refined control of chakra. .

In Naruto, Kabuto's talent is extremely powerful. When he first appeared, the scalpel used by Kabuto attached chakra to the scalpel, thereby increasing the power of the scalpel.

[Wind Blade] is much more powerful than Kabuto's scalpel. Not only is it covered with physical chakra, it can also be controlled from a distance.

"It turns out it's the runes..."

Musashi sighed, feeling relieved at the same time.

If he really relied on his own strength to achieve the effect of [Wind Blade], then Asuma would be at least on the same level as Tsunade.

When Kakuzu and Hidan encountered a strong man of Tsunade's level, apart from running away, Musashi really couldn't think of another possibility.

"Brother, I succeeded!"

Holding the finger blade and injecting chakra, a clear sound like the chirping of insects suddenly came from the blade. When Asuma saw this, he showed off to Shinnosuke extremely excitedly.

"Yeah, I will give it to you from now on."

"Brother, you gave me the weapon. What do you use for yourself?"

"I'll just order another one."

Shinnosuke lovingly picked up Asuma, feeling relieved but also a little worried, so he solemnly told: "The Chakra Blade is the weapon that my brother uses to kill enemies on the battlefield. Remember, it can only Use it on your enemies, not your own people."

"I know..." After receiving the gift, Asuma was so happy that she immediately agreed. Suddenly something came to mind, and then she asked doubtfully: "Brother, can I use it to practice ninjutsu? Use it on the wooden stakes." kind."

"As long as it's not directed at the villagers, it can be used." Shinnosuke scratched the bridge of Asuma's nose.

It's true that Asuma was really naughty in the past. He always bullied children of the same age because of his status as Hokage's son.

It happened that he had been learning ninjutsu since he was a child. Several, or even dozens of children of the same age were no match for him alone.

Every time he got into a fight or got into trouble, it was Shinnosuke who wiped his ass.

Now that he has a weapon, if Shinnosuke does not give him a serious warning, he is really afraid that Asuma will commit an unforgivable sin.

"The secret of [Wind Blade] turns out to be the weapon..."

Musashi nodded secretly in his heart and had a bold idea at the same time.

He is now a medical ninja, so it is normal to carry a scalpel with him.

If we learn from the design ideas of [Wind Blade], can we create a weapon unique to Musashi?

A powerful weapon that can be controlled from a distance like the [Wind Blade]!
