I see!
Shihouin Naraku's improved constitution and spirit had caused the amount of chakra in his body to surge rapidly, but he hadn't noticed this change. Whether in battle or performing medical ninjutsu, he was still refining chakra on his own.
He didn't immediately realize that his speed of refining chakra had become much faster.
Without the system's help, the rapidly surging chakra would have directly damaged his meridians and organs.
Therefore, the system intercepted the dangerous amount of chakra, only slowly increasing the total amount in Shihouin Naraku's body.
"Understood."
Shihouin Naraku knew the system was helping him. Just think about it—among the shinobi in the world who possessed huge amounts of chakra, which one had a weak constitution?
Even Uzumaki Naruto had the genetic advantage of the Uzumaki clan and the support of the Kyuubi.
Of course, ordinary shinobi wouldn't face problems like Shihouin Naraku's. With poor physical fitness, they simply wouldn't develop so much chakra.
The key point was that Shihouin Naraku differed from ordinary people. His spirit and soul were too strong, too extraordinary, which directly led to his body being unable to withstand the surge of chakra!
After realizing this, Shihouin Naraku felt troubled.
"So my body can't keep up with the speed of my spirit's improvement!"
"Being mentally strong brings many benefits, but also many problems."
Shihouin Naraku never imagined that one day he would be troubled by a certain quality of being too powerful.
Of course, this could also be considered a fortunate problem!
"System, according to your calculations, how much chakra can I withstand at most?"
[Fifty per cent!]
"At most 50%. That means unless my constitution improves, the remaining 37% of chakra cannot be absorbed anyway."
[Yes!]
"If I were to absorb it all at once, how much chakra could I take at most?"
[32%! However, the host's meridians will be slightly damaged, and the body organs will also be burdened! And within one month, chakra can no longer be absorbed!]
Shihouin Naraku thought he could withstand such consequences, so he said directly: "System, I want to accept 32% chakra infusion, now!"
[Ding! Do you want to accept the 32% chakra infusion?]
"Yes!"
"BOOM!!!"
As soon as Shihouin Naraku finished speaking, he suddenly felt an enormous amount of chakra being born within his body.
In an instant, Shihouin Naraku's face turned crimson.
His organs and meridians transmitted feelings of swelling and pain as the massive amount of chakra flowed rapidly through his body with great momentum.
"Crack!"
The tree stump where Shihouin Naraku sat cross-legged suddenly developed obvious fractures and then collapsed completely.
Struggling to endure the burden on his body, Shihouin Naraku stood up. With him as the centre, the violent energy instantly created a whirlwind, and the ground of the training field cracked like a spider web.
Strong winds flattened the flowers and plants near the ground. Dense trees bent under the pressure, and leaves were blown high into the sky.
The raging energy stirred up clouds of dust that spread rapidly in all directions.
After what seemed like forever, the area around Shihouin Naraku gradually returned to calm.
Feeling the surging chakra in his body and his rapidly growing strength, a smile appeared on Shihouin Naraku's handsome face.
It was then that he was surprised to find he couldn't see the ground.
Within a hundred meters around him, the hurricane created by the violent chakra surge had cracked the earth, forming a huge crater in the ground!
"Why is it so extreme? Is it because I absorbed too much chakra at once?"
Shihouin Naraku felt somewhat embarrassed and endured the slight pain in his body as he walked out of the pit step by step.
There was a slight sound beneath his feet. Looking down, he saw that each step had left deep footprints in the ground.
"The improvement is too great. I need to quickly adapt to my current strength."
Shaking his head and controlling the power under his feet, Shihouin Naraku walked out of the deep pit and began to practice with Kurikara in hand.
It took two days for Shihouin Naraku to adjust to his new strength.
This also meant his power had risen to a new level again!
...
On this particular day, Shihouin Naraku was working out in his private training field to improve his constitution!
With his upper body exposed, he wielded Kurikara and practised his swordsmanship with every strike!
Drops of sweat slid down his skin, and his well-defined muscle lines gleamed under the sunlight, displaying the beauty unique to strength, making anyone want to reach out and touch them.
Although Shihouin Naraku was simply practising sword swings with Kurikara in hand, he concentrated all his attention and exerted his full strength with each movement. The pitch-black tip of the sword always landed precisely in the same place.
This alone proved Shihouin Naraku's superb swordsmanship and perfect control over his strength.
"Flip..."
From a large tree outside the private training ground came the sound of turning pages. Hatake Kakashi sat sideways against the tree trunk, reading his Icha Icha book.
Shihouin Naraku had already noticed Kakashi but said nothing as he continued to practice with full concentration.
After a while, he finished his exercise and walked outside the training ground, then picked up a clean towel and wiped the sweat from his body.
While drying his face, Shihouin Naraku asked, "Why are you coming to me instead of being a good sensei?"
"I heard that Naruto and Uchiha Sasuke's team passed your test. What's it like being Naruto's sensei?"
Hatake Kakashi put away his book, looked at Naraku and said: "What do you think? It should be boring. But Naruto and the others are actually quite good, each with their own strengths."
"During this time, we've been taking D-rank missions every day.
The team has become a little restless, especially Naruto, who pesters me constantly, wanting me to teach him powerful jutsu.
Although Sasuke doesn't say it directly, the meaning in his eyes is too obvious.
As for their other teammate, Sakura, she hasn't realized what being a shinobi truly means and is still quite naive..."
Shihouin Naraku watched Kakashi talking nonstop and noticed he had changed in this short time. It seemed that becoming a sensei was indeed good for Kakashi.
"So, why have you come to me? Just continue being their sensei."
Hatake Kakashi spread his hands, his lazy eyes revealing a trace of helplessness, and said: "Naruto and Sasuke witnessed our fight. Especially after seeing your performance, they've become very arrogant.
All they want is to learn powerful jutsu.
I want them to seriously build a solid foundation, but they really don't listen."
"What's even worse is that Naruto has caused trouble again. He's been jumping around all day bragging about your strength to his friends and teammates and then showing off the Kage Bunshin he's learned. This has made this year's Academy graduates very restless."
"I went to ask Hokage-sama, and he told me to come find you."
Shihouin Naraku frowned as he listened to Hatake Kakashi's explanation. He hadn't expected such developments.
In the original timeline, Uzumaki Naruto never behaved like this.
Perhaps this was the butterfly effect caused by the battle between Shihouin Naraku, Hatake Kakashi, and Might Guy.
Uzumaki Naruto is causing trouble, Uchiha Obito is making his move, and more. The impact that Shihouin Naraku had on the shinobi world was slowly becoming apparent!
