"Shinji-sensei, are these really useful?"
Looking at the training written in the physical training notebook, Shikamaru felt a bit of a headache.
Various squat training, weight-bearing training, running training. These aren't the problem, the problem is in the quantity. 500 reps per set, then six sets, and cycled through all at once.
"You think it's useless?" Shinji asked with a smile, causing Shikamaru to nod uncertainly.
"Naruto, come here for a moment." Shinji called out to Naruto, who wasn't far away.
"Coming! Sensei!" Hearing Shinji's call, Naruto quickly jogged over.
Shinji patted Naruto's hair, pointed to the weights on his feet, and asked, "How many pounds are you carrying now?"
Naruto jumped, feeling the weight as he spoke, "Hmm... 30 pounds on each foot. Sensei, I might need to change them, I feel they're a bit light."
Shinji nodded with a smile, pointed at Shikamaru, and said, "Naruto, take off your weights first, then go punch Shikamaru."
"Huh?!"
Hearing this, Naruto was a bit confused.
Punch Shikamaru?
"No, sensei, Shikamaru is my friend." As he said this, Naruto looked at Shinji with a serious expression.
Slap!
"I wasn't telling you to actually punch him, but to let Shikamaru feel your speed after taking off the weights."
Shinji slapped Naruto on the back of the head in annoyance. This kid really couldn't think straight.
Hearing Shinji say this, Naruto quickly bent down to take off his weights, then looked at Shikamaru and said with some hesitation, "Shikamaru, I'm very fast, be careful."
Shikamaru nodded.
Just as he was about to make a move to block—
Whoosh—!
A figure instantly came straight towards him.
"Damn! Is this going to send me flying?!"
The moment Shikamaru had that thought, he felt the pain of a heavy blow landing on his blocking arm, and his whole body was sent flying backward. He quickly rolled in the air to use the momentum to land on the ground, his feet sliding a shallow trench on the ground before he finally stopped.
Then, with a look of disbelief on his face, he looked at Naruto, who was looking panicked.
"Shikamaru, are you okay?!" Naruto quickly ran forward, looking at Shikamaru with a worried expression.
"I'm fine, I just feel like a bone might be a little cracked." Shikamaru waved his hand as he spoke, grimacing as he did.
Choji, who had gathered nearby, looked at Shikamaru's slightly trembling hands, took out a can of ointment and bandages from his pack, and began to bandage him.
Shinji waited for Choji to finish bandaging, then his hands glowed green, and he began to heal Shikamaru's arm.
Feeling the warmth coming from his arm, Shikamaru looked at Shinji with some surprise. "Sensei, you know medical Ninjutsu?"
"No, I can use Yang Attribute Chakra to promote the healing of your arm, and incidentally help Choji's ointment work faster."
Shinji shook his head in denial, after all, he really didn't know medical Ninjutsu.
Shinji felt he was finished, so he withdrew his Chakra, and then looked at Shikamaru and asked, "How about it? Do you believe it now?"
Shikamaru nodded.
"Perhaps it's more than that, sensei must have helped Naruto with something, or..."
Shikamaru stopped speaking, then said again, "Just carrying weights alone can only increase speed at most. It's impossible for strength to increase as well."
Shinji looked at Shikamaru, who had hit the nail on the head with one guess, and nodded in approval. "That's right, I often have Naruto use Chakra to nurture his muscles and bones when he has nothing to do."
He then looked at Choji and Shikamaru and quickly added, "Of course, this method is only for Naruto. After all, not everyone has enough Chakra to use it like this."
It's no wonder Shinji had to explain it specifically, after all, this method was something he had come up with himself, using Chakra to temper the body. It was also something he first used on himself, but he used Yang Attribute Chakra.
After all, not everyone is from the Raikage's lineage, capable of using Lightning Release Nature Transformation to strengthen their bodies, and even practice taijutsu with it.
Shikamaru said, "No wonder, you brought out the prescription, sensei. So, this is what you were waiting for."
If one really trained according to what was written above without nurturing the body, there might be no problem in the short term. But over time, once hidden injuries on the body erupt, it will make it impossible for someone to even be a ninja.
Shinji spread his hands and said, "That's right, if you want to talk about the best effect, it's nurturing one's body with their own Chakra, just like I said before."
He turned to Choji and said, "Choji might have a chance, but at most only once every half a month."
Considering Choji's physique and his usual energy intake, this is the most he can do.
Hearing this, Shikamaru looked at Choji with a bit of envy, wondering if he should try it too?
But seeing Choji's physique, which was twice his size, he shook his head.
Forget it, he'd probably burst before he could even eat enough.
Naruto asked, resting his hands behind his head, looking a bit puzzled, "Sensei, what are you and Shikamaru talking about?"
Shikamaru found Naruto's reaction strange. It made no sense that he would use it but not know what he was talking about, right?
But thinking about Naruto's usual carefree personality and wild imagination, Shikamaru couldn't help but mutter, "This luck is really too good."
Shinji said, "Let's go, I'll tell you about Chakra Nature Transformation. Clone, come over and check on Shikamaru and the others' training."
The Shadow Clone waiting nearby immediately nodded. "Thank god. I was afraid my brain would overload later and I would explode on the spot."
The Shadow Clone quickly took Shikamaru and Choji aside.
Because the jutsu hadn't been dispelled yet, Shinji was a bit confused. "To scare my Shadow Clone like that, Naruto, what did you just do?"
Naruto said, "Uh, I just asked Clone-sensei, since Wind Release Nature Transformation is sharpness and cutting, why are trees uprooted when there's a strong wind, instead of being cut into pieces of wood?"
"Also, Wind Release Nature Transformation makes Chakra sharp, so wouldn't it be more convenient to use Wind Release when I'm cooking and cutting vegetables?"
As Naruto spoke, he began to cross his arms and tilt his head, clearly starting to think about the answer to this question again himself.
"..."
The air suddenly fell silent, and Shinji's eye twitched uncontrollably.
His fingers silently pressed against his constantly throbbing temples. He finally understood why the Shadow Clone acted like he would explode if he stayed for another second.
Because of the orders Shinji gave, even if the Shadow Clone found it nonsensical, he would still personally think about Naruto's questions.
Shinji said with a full smile and a very gentle tone, "Naruto, if you think about such boring things again, I'll first let you properly experience the joy of copying homework."
