Naruto Shadow Mage

Ding!

"Player, you have used the Tree Climbing Training Card. Time limit: 60 minutes. Tree Climbing Training starts now!"

"Huh? Only 60 minutes?"

The APP's voice appeared again, leaving Koshino stunned.

60 minutes? That's just one hour!

During his three months of transmigration, Koshino had undergone tree climbing training countless times, each session lasting an entire day with only minimal progress.

So, when the APP mentioned that the Tree Climbing Training Card only had a 60-minute limit, the enthusiastic Koshino couldn't help but feel a bit deflated, not expecting much from the card.

However, as Koshino approached a tree without even laying down a thick cushion, ready to grit his teeth and make the most of the 60 minutes, a cool sensation suddenly spread throughout his body, causing his dark pupils to constrict slightly!

"Is this chakra? The Tree Climbing Training Card enhances chakra?"

"Oh my! Such abundant chakra, comparable to Naruto Uzumaki's, no, to a tailed beast's!"

As the effects of the Tree Climbing Training Card manifested, Koshino was astonished by the APP's powerful capabilities!

In his usual tree climbing training, what had made things difficult for Koshino?

One was the difficulty of the training itself, and the other was the lack of sufficient chakra, making each session time-consuming and exhausting.

Now, with the Tree Climbing Training Card providing abundant chakra, Koshino's eyes gleamed with determination. Without hesitation, he channeled chakra to his feet, remembering the process from before, and placed one foot on the tree trunk.

"With enough chakra, tree climbing is a piece of cake!"

"Wait! The APP has another prompt!"

Originally, Koshino thought that having abundant chakra was the extent of the Tree Climbing Training Card's benefits. He didn't expect there to be more. The APP's next prompt confirmed this.

Ding!

"Player, you have used too much chakra. Receiving penalty."

"Player, you have used too little chakra. Receiving penalty."

"Player, your chakra distribution was imperfect. Receiving penalty."

Zap! Zap!

Each time the APP's voice echoed in Koshino's mind, it highlighted an error he made during tree climbing training.

And every mistake came with a penalty!

An invisible current coursed through Koshino's body, causing a nerve-wracking pain to spread throughout him. This pain not only served as a reminder but also deepened his impression of the training. Every mistake Koshino made during tree climbing training was corrected after a single APP penalty, allowing him to improve each time.

As time passed, especially with fewer APP error prompts, Koshino was surprised to find that he had completed the previously arduous tree climbing training!

And he completed it perfectly!

What does perfect completion mean?

Simply put, every bit of chakra Koshino used during tree climbing was perfectly allocated, reducing chakra waste and increasing efficiency.

Previously, Koshino's chakra reserves could only sustain one use of the Shadow Imitation Technique. Now, after perfecting his tree climbing training and minimizing chakra waste, Koshino could use the Shadow Imitation Technique twice. With maximum effort, he could even use it three times—a significant improvement!

Then, the APP announced that the Tree Climbing Training Card's time limit was reached. Koshino, not having felt the passage of time, was in disbelief.

But when he used his chakra again for tree climbing, whether hanging upside down or standing on the trunk with one foot, Koshino was thrilled, realizing that the training was real and not a dream!

With the perfect training effect from the Tree Climbing Training Card, Koshino immediately commanded the APP to use the Water Walking Training Card, determined to complete all his training in one day.

As Koshino arrived at the pond in the deer farm, ready to train with the Water Walking Training Card, he didn't notice two figures slowly approaching from a distance.

"Sigh, another death. Choza, it seems we've only met at funerals lately. It's been a while since we've taken a stroll like this."

"Yeah, Shikaku! Hey, want some chips?"

"Uh, no thanks!"

Not far from Koshino's training spot, the two figures approaching were Nara Shikaku and Akimichi Choza, having just left a funeral.

The Nara and Akimichi clans were close, with Shikaku and Choza being members of the current "Ino-Shika-Cho" trio. Koshino often saw Choza and Yamanaka Inoichi together, so it wasn't unusual for Shikaku to bring Choza to the deer farm for a walk.

However, when Shikaku led Choza to the pond, they saw Koshino training. Choza, known for his love of snacks, pointed excitedly at Koshino and laughed, "Shikaku, look! It's a miracle to see someone from the Nara clan being so diligent!"

"Oh?"

Following Choza's pointing, Shikaku was equally surprised, evidently finding it hard to believe.

Laziness was contagious.

The Nara clan possessed excellent genes, but laziness was deeply ingrained, as evidenced by Shikaku and Shikamaru in the original story.

Because of this laziness, many in the Nara clan squandered their talents.

Before becoming clan leader, Shikaku didn't mind the Nara clan's laziness. But during wartime, laziness equated to slow death. Under the previous clan leader's "laziness," Shikaku took over, contemplating reforms. Choza's remark shifted Shikaku's attention to Koshino.

"Oh, it's Koshino! He's always been a diligent child, but… sigh!"

Shikaku admired Koshino's dedication to training, but recalling Koshino's tragic background and the death of his parents on the battlefield, Shikaku couldn't help but sigh and shake his head.

However, while Shikaku sighed, Choza watched Koshino with great interest, especially as Koshino perfected his water walking training using the Water Walking Training Card in just ten minutes. Renowned in the ninja world, Choza was astonished, forgetting to eat his chips as he exclaimed, "Shikaku, your clan's Genin is incredible! Perfecting water walking in just ten minutes. Wait, that kid looks familiar!"

"Shikaku, who is he?"

"What? Ten minutes?"

Hearing Choza, Shikaku realized Koshino was training in water walking, leaving him stunned as he murmured, "Choza, he's Koshino!"

"Not a Genin, but that four-year-old Koshino!"
