"Player, sorry, you haven't learned any skills related to physical attributes. Would you like to view your training progress?"
"Sigh, just as I thought—wishful thinking!"
Ever since crossing over to this world, Yueye had fantasized about gaining three specific powers: first, the Body of the Sage; second, the Eternal Mangekyō Sharingan; and third, the Rinnegan.
He didn't need to explain the last two—any fan of Naruto knows those are the cheat codes of this world. Anyone with the Eternal Mangekyō or the Rinnegan is basically walking the path of invincibility. But as a seasoned Naruto fan, Yueye knew something more: the Body of the Sage was just as overpowered, even if fake fans didn't realize it.
Think about it—how did Naruto Uzumaki survive the early parts of the original series?It was thanks to his Uzumaki clan's constitution, the so-called Body of the Sage!
That constitution gave him nearly limitless spiritual and physical energy. With even minimal training, he could build up chakra on par with a tailed beast. More importantly, the Uzumaki body was like a cockroach—its vitality was absurd. Naruto got into life-threatening situations over and over, and if he didn't have that Uzumaki bloodline, he'd have died at least twenty times in the early arcs.
So if Yueye could have even half of Naruto's physical constitution, he was confident he could master the Nara clan's secret techniques before turning five—surpassing even prodigies like Kakashi or Itachi would be no problem!
Unfortunately, now that the app had made its restrictions clear, his hopes were dashed.
Yueye followed the app's instructions step by step to figure out how it worked. First, he pulled up his own training progress.
"Huh?"
Shadow Imitation Technique?
According to the app's display, the first thing he saw was the familiar Shadow Imitation Technique, with a proficiency level shown as 30/100.
"I thought I'd already mastered it, but I haven't even reached a third yet?"
"Wait a second… Didn't the app say I could modify skill progress? Doesn't that mean I can change my Shadow Imitation progress?"
Yueye quickly asked the app:"App, can I modify the training progress of Shadow Imitation Technique?"
"Player, Shadow Imitation Technique is currently being trained. Modification is allowed."
"Great! Then change it to 100/100!"
Ding!"Player, Shadow Imitation Technique progress set to 100/100. Congratulations, you've completed mastery of the Shadow Imitation Technique."
Just like that?
After three grueling months of only scratching the surface of the technique, it was mastered instantly?
As the app notification echoed in his mind, Yueye's eyes were filled with disbelief. He quickly restored some chakra, then made a hand sign aimed at a nearby reindeer:
"Shadow Imitation Technique!"
Buzz!
Buzz!
The moment he formed the seal, Yueye felt his chakra surge—and then something surprising happened. The transformation of his chakra had become perfect.
Not a trace of chakra was wasted converting to Yin Release—the exact nature needed for the Nara clan's jutsu. Even more shocking, his shadow shot forward like a spear, and in just seconds it linked up with multiple reindeer shadows in front of him.
Then, with just a thought, the reindeer would move as he moved.
"It really worked!? The app didn't lie!"
As his freshly recovered chakra ran out, Yueye collapsed to the ground, legs numb—but a wide, satisfied grin spread across his sweaty face.
In the original story, Shikamaru mastered this technique at age 12, and that was already considered top-tier talent. Yueye had just done it at four. That didn't make him a genius…
It made him a monster.
For the first time, in this world full of monster-level ninjas and Kage-tier powerhouses, Yueye felt he had a shot at surviving. Even in the same era as Kakashi and Itachi—even knowing what terrifying enemies lay ahead—so long as he had this app, he believed he could control his own destiny… maybe even live better than Naruto or Sasuke.
Seated on the ground, Yueye began restoring chakra again. He didn't know if it was the repeated use of Shadow Imitation or the app's influence, but his chakra not only recovered—it grew denser, purer.
Holding a cheat tool like the app, and aiming to surpass legends like Kakashi and Itachi, Yueye suddenly realized that… training was actually fun. He was eager to begin his next grind.
"Hm…"
"The app's progress modification is amazing—but it looks like it only works on jutsu I've already started training. Like the Shadow Strangle Jutsu—even though it's a direct upgrade of Shadow Imitation, because I haven't learned it yet, I can't modify it through the app."
"That means for now, besides chakra gathering, the only real options I have are the basic chakra control exercises."
Yueye made up his mind: it was time to start tree climbing and water walking—the basic foundation of chakra control.
Don't underestimate basic training!In his three months since crossing over, Yueye had created so many comedy-worthy fails while tree climbing.
Thankfully, he was smart enough to place a thick mat under the tree each time. Otherwise, after falling that many times, his butt would've been bruised beyond repair—and there'd be no way he could quietly hide in the reindeer ranch to avoid those gloomy funerals.
Back when he was just reading the manga, Yueye thought tree climbing and water walking looked easy. Even Naruto, a total dunce, managed it in a few days. Yueye, inheriting the Nara clan's intelligence, assumed he'd be like Sakura—mastering it instantly.
But reality hit hard. Chakra control wasn't that simple.
It required constant attention—too little chakra and he'd slip, too much and he'd blast off the tree like a rocket. Add to that his naturally small chakra pool, and every training session took forever with barely any progress.
Eventually, he chose to focus on Shadow Imitation first. Once his chakra reserves reached the level of a Genin, then he'd return to tree climbing and water walking.
But now, thanks to the app, he'd mastered Shadow Imitation—and his confidence had skyrocketed. Chakra control training was next.
Especially when he looked into the app's inventory and saw two floating cards: one labeled Tree Climbing Training Card, and the other Water Walking Training Card.
Trusting the app's quality, Yueye lit up with excitement.
"App, use the Tree Climbing Training Card!"
