"This is the Chakra Extraction scroll, and the Three Body Technique!"
Two scrolls lay before Shimura Kaede, marking his first encounter with the power of this world.
Even if he had wanted to learn before the age of three, Aburame Ryoma had refused him.
The reason was simple: Danzo wouldn't allow it.
"Great! Thank you, Father!"
Shimura Kaede picked up the scrolls with a look of joy; this time, he wasn't faking it, he was genuinely happy.
After all, in the Ninja World, strength was paramount.
Danzo had so many enemies, and he couldn't always protect himself. Plus, now that he had a system, he naturally had to work hard to become stronger.
"Very good, full of spirit!"
Danzo nodded with satisfaction at Shimura Kaede's appearance.
"You seem very eager to learn Ninjutsu?"
Aburame Ryoma had naturally reported Shimura Kaede's previous attempt to learn Ninjutsu to Danzo Shimura, but after being refused, Shimura Kaede hadn't brought it up again.
"Yes!"
Shimura Kaede nodded, secretly thinking to himself.
"That Aburame Ryoma, always tattling. Once I inherit my dad's legacy, I'll show him!"
Danzo looked at Shimura Kaede: "Why?"
Shimura Kaede held the scrolls in his arms and said with a smile.
"So I can protect Father and prevent him from getting hurt again!"
"Protect me?"
Danzo Shimura's heart trembled, an indescribable emotion constantly swirling within him.
"Hmph!"
"If you want to protect me, you'll have to work twice as hard, otherwise, you won't be qualified to say such a thing!"
A hint of tenderness flickered in Danzo Shimura's eyes, but his tone remained as cold as ever. If Shimura Kaede hadn't been mentally mature, he might have genuinely felt disappointed.
"I will work hard!"
Shimura Kaede said seriously, thinking to himself: "If you get killed by Sasuke, I will work hard to inherit all your assets, Dad, don't worry!"
His dad had too many enemies, and Shimura Kaede felt helpless.
When he heard about Kato Dan's death, Shimura Kaede's heart still trembled, fearing that his own dad was responsible.
After all, whenever something bad happened, blaming Danzo was always a safe bet.
"You go ahead and extract Chakra; I'll stay here with you!"
Danzo Shimura was concise, directly telling Shimura Kaede to start learning Chakra extraction. He had already prepared to take the day off.
The speed of Chakra extraction could also reflect a person's talent.
Those with good talent might succeed in half a day, while those with poor talent might take three or four days to extract even a trace.
"How long did it take me back then? Four hours or five hours?"
"Anyway, the monkey was half an hour faster than me, how annoying!"
Danzo thought to himself, while Shimura Kaede picked up the scroll and began to read.
Chakra extraction is a combination of spiritual energy and body cells.
Using spiritual energy to extract cells from the body is actually a way to squeeze the body's potential.
It might not be noticeable in the short term, but over time, it can severely damage cells, destroy the foundation, and significantly shorten a person's lifespan.
Except for those with special constitutions or unique individuals, the average lifespan of a Ninja is around fifty years.
Of course, this doesn't account for dying in battle.
Undeniably, this method of gaining strength does affect one's lifespan.
This was also the reason Danzo didn't let Shimura Kaede extract Chakra before he was three years old, because such an act would damage the foundation and cause significant harm to a child.
"Spiritual energy and cells in a one-to-one ratio, thereby extracting Chakra, the principle is to utilize..."
Shimura Kaede read the scroll very carefully. Although extracting Chakra would shorten his lifespan, the Ninja World was so chaotic that only those who were alive had the right to consider their lifespan.
It only took a few minutes for Shimura Kaede to finish reading the scroll.
After putting down the scroll, Shimura Kaede sat cross-legged on the floor and began his first attempt at Chakra extraction.
"Has he started?"
Danzo Shimura sat calmly on the tatami mat, already prepared for questions.
"What should I say later?"
"Encourage him? Or say 'continue' with a cold face?"
"Will Kaede think I don't care about him like this?
Kaede is usually quite obedient, shouldn't I encourage him a bit?"
"Later, if Kaede asks for my help, I'll say, 'It's okay, Kaede, you're already amazing, truly my son...'"
Just as Danzo Shimura was pondering, he suddenly felt a surge of airflow in the room. Although very faint, it couldn't escape Danzo Shimura's perception.
"Hmm?"
Danzo Shimura looked over in confusion, then froze in place.
Shimura Kaede was sitting cross-legged on the ground, with a faint trace of Chakra already swirling around his body. The deep green Chakra, like wind, continuously rotated around Shimura Kaede, creating a slight airflow.
"He succeeded?!"
Danzo Shimura looked utterly disbelieving. How much time had passed since Shimura Kaede started extracting?
A minute? Or thirty seconds?
He himself had spent four hours.
That was already considered fast.
Could his son have learned Chakra extraction beforehand?!
Impossible!
Just now, there wasn't a trace of Chakra in his body!
Danzo Shimura's face was full of shock. Could it be that his son was a genius?
A true genius?!
"Hahahahaha!!!"
"Monkey, this time you lose, my son is a true genius!"
Danzo's loud laughter interrupted Shimura Kaede's Chakra extraction. In fact, he could have continued, but there was no need; he was still young, and extracting too much Chakra would damage his body.
"Father? You...?"
Looking at Danzo Shimura, who was laughing uncontrollably, Shimura Kaede secretly rolled his eyes.
"What are you laughing about? Do you really think you're an Uchiha?"
"It's nothing! You succeeded?"
Danzo's laughter stopped abruptly.
Not wanting to lose his dignity in front of his son, he stopped laughing, but the smile on his face was still undeniable.
"Yes, I have succeeded!"
Shimura Kaede was also a little excited at this moment, constantly checking the Chakra within his body, a very novel sensation arising spontaneously.
"Excellent! Truly my son!"
"Really?"
Shimura Kaede looked up: "How long did it take Father to extract Chakra back then?"
"Cough, cough, cough!!!"
Danzo Shimura coughed a few times, then pulled out a piece of paper and threw it in front of Shimura Kaede.
"A little faster than you, probably!"
"This is a Chakra test paper. If you input the extracted Chakra into it, it will show your Chakra nature!"
Shimura Kaede didn't think much of it and believed him.
After all, Danzo also had high talent, and his strength was Kage-level. Although later, due to aging, not fighting for a long time, and the transplantation of Sharingan and Hashirama cells, he lost his original fighting style and seemed weak.
However, the current Danzo, with his Wind Release, was still a top-tier master.
A few years ago, he was still in the Land of Rivers, constantly clashing with the Third Kazekage, and the two had many encounters.
Although Danzo was always suppressed and at a disadvantage, the Third Kazekage couldn't defeat Danzo, and Danzo could tie down the Third Kazekage for a long time.
"Okay, Father!"
Seeing that Shimura Kaede was fooled, Danzo Shimura secretly breathed a sigh of relief.
Sometimes, when a son is too much of a genius, the father feels a lot of pressure too.
"A single Wind Release nature?"
As Shimura Kaede inputted Chakra, the Chakra test paper in his hand was directly cut in half, and there were no other changes.
Seeing this, Danzo Shimura couldn't help but feel a little disappointed.
While having more Chakra natures didn't necessarily mean being stronger, having multiple natures certainly provided more techniques.
If someone had five natures like Hiruzen Sarutobi, they would undoubtedly become a Kage-level master if trained properly. Orochimaru was the best example, even though he mostly used his snakes.
"Very good, you can inherit my Wind Release!"
Danzo Shimura shook his head and didn't think much of it. After all, natures could also be cultivated later, and a single nature wasn't necessarily bad.
Wasn't he himself a single Wind Release user? It was normal for his son to be the same!
