Naruto Shadow Mage

"A special item?"

"Besides the Nara clan's secret medicine, even weights are considered special items by the app?"

"And it comes with a buff for accelerated taijutsu training? This is amazing!"

Koshino's eyes sparkled with joy. The app's discovery of the miraculous effects of the weights, even if it's only a 10% acceleration in taijutsu training, was a timely solution to Koshino's urgent needs.

It's important to note that the app's effect on modifying training progress only applies to ninjutsu and secret techniques.

For things like throwing weapon training and taijutsu training, Koshino had to complete them step by step himself. Otherwise, he wouldn't have spent so much time following the Uchiha clan's secret technique scrolls to master throwing weapons. He could have simply modified the training progress and completed it early.

Moreover, compared to throwing weapon training, taijutsu training is undoubtedly more difficult.

For throwing weapon training, Koshino could follow the methods recorded in the Uchiha clan's secret technique scrolls, gradually completing it with the use of throwing weapons. In contrast, taijutsu training without a skilled teacher would be tough. Given its rigorous nature, Koshino could hardly make any progress.

Now, with a 10% acceleration in taijutsu training, Koshino is no longer worried about the slow progress in mastering taijutsu.

Then, Koshino turned his attention to Guy, silently making plans.

With a future taijutsu master by his side, Koshino thought it would be foolish not to make the most of it.

Next, Koshino took Guy's weights and experimented to see if they would increase the percentage of taijutsu training acceleration.

Indeed, combining the weights for both arms, Koshino found that the 10% taijutsu training acceleration jumped to 20%.

Through further exploration, Koshino realised that for every 10 kg of weight, there was a 10% increase in taijutsu training acceleration.

If Koshino could train under 100 kg of weights, he would achieve an astonishing 100% acceleration in taijutsu training. Unfortunately, after discussing it with Guy, Koshino learned that without harming his body, 10 kg was his limit, which meant he could only gain a 10% training boost.

However, understanding that any weight could activate the app's taijutsu training boost, Koshino felt he had already gained a lot. Then, watching Guy struggle to put on his weights, Koshino, with a mind to test, asked Guy, "Guy, can I train with you from now on? I noticed during our spar that your taijutsu is really good. Could you guide me in taijutsu training?"

"Huh?"

Guy was momentarily stunned by Koshino's request and then asked, "Koshino, you're from the Nara clan. Didn't you train in taijutsu within your clan?"

"No, I didn't train in the clan's taijutsu."

Shaking his head helplessly, Koshino sighed deeply and said, "Our Nara clan members usually focus on secret techniques, so there are few who concentrate on taijutsu. Moreover, our taijutsu is nowhere near as strong as the village's Strong Fist style. I noticed you were using the Strong Fist style, which is why I thought to ask for your guidance."

"I see!"

After Koshino's explanation, Guy understood the situation.

Then, giving Koshino a thumbs-up, Guy nodded with a smile and said, "Koshino, if you're not afraid of hardship, then train with me!"

"My training is extremely tough! For the burning youth, let's work even harder!"

"Alright!"

Guy was straightforward and disliked beating around the bush.

It just so happened that Koshino matched Guy's personality, and being from the Nara clan, Guy also had the intention to befriend him. In training, Guy not only withheld nothing but also patiently taught Koshino the intricacies of taijutsu.

Especially the next day, when Guy brought weights specifically for Koshino, it touched Koshino's heart.

In Konoha, the closest person to Koshino was Nara Shikaku, the only one who had entered his heart.

Guy, on the other hand, was just a passerby.

Had Koshino not known him as the future "Emperor Guy" from the original story, he wouldn't have bothered at all. But Guy, who seemed simple-minded, was actually very considerate.

Don't underestimate those weights.

The combined weights for both arms and legs totalled just 10 kg. Given Koshino's status in the Nara clan, getting a set would be as easy as waving a hand, not a problem at all.

But what Koshino valued was that Guy always thought of him.

So, besides Shikaku, Guy became the second person to enter Koshino's heart.

As their hellish training progressed, Koshino and Guy formed a deep bond, becoming very close friends.

Time flew by, and two months later.

"Leaf Whirlwind!"

"Leaf Whirlwind!"

"Boom!"

"Boom!"

Before dawn, in a secluded training ground in Konoha, Koshino and Guy were already there training.

With Guy's help, Koshino underwent two months of hellish training and finally grasped the basics of the Strong Fist style.

Moreover, after two months of hard training, taijutsu was no longer Koshino's weak point but rather one of his strengths!

During their spar, both had removed their weights, moving swiftly.

Using the same techniques, Koshino might be slightly slower and weaker than Guy. But in pure taijutsu, even Guy noticed Koshino's significant improvement. After hundreds of exchanges without a clear winner, Guy wiped the sweat from his forehead and said with a smile:

"Koshino, you're improving fast! To reach this level of taijutsu in just two months, you truly are a genius!"

"What genius? Does a genius not need to work hard?"

"Guy, don't think I don't know you're not using your full strength! Are you saving it to challenge Kakashi?"

In their two months together, Koshino and Guy became close friends.

A month ago, Koshino learned that, like in the original story, Guy had started challenging Kakashi Hatake.

However, Kakashi was at his peak, and with Obito's Sharingan, defeating him with taijutsu was even harder. As a result, each time Guy challenged Kakashi, Koshino saw Kakashi easily overpower Guy using the Sharingan's insight.

But Guy's constant return to intense training after each defeat further fueled Koshino's desire to win.

Now, seeing Guy preparing to challenge Kakashi again, Koshino couldn't help but get excited.

Because at this moment, Koshino wanted to know if, after two months of hard training and comprehensive improvement, he was qualified to face a Jonin!
