Naruto: My Progress in Konoha.

Fifteen minutes later—

The two shadow clones practicing Rasengan reached their limits and dissipated into clouds of chakra, carrying their accumulated experience and memories back into the original body.

Uchiha Haruki, who had been training in Mind Reflection Technique, furrowed his brow slightly. He immediately diverted a portion of his focus to merge the returned experiences and memories.

Moments later, he opened his eyes, pulled up his status panel, and quickly glanced over the results.

He noticed that Rasengan's proficiency had increased by 30 points.

If he had trained personally using the same amount of chakra, he estimated he could've gained around 45 points—meaning the shadow clone's training was only two-thirds as efficient as the original body.

And this was short-term efficiency.

If he allowed the clones to continue endlessly without resetting their state, that efficiency would steadily drop, until eventually hitting a bottleneck and contributing nothing.

But Haruki obviously wouldn't let that happen.

Casting a quick glance at the two other shadow clones still training Genjutsu: Sharingan, Haruki made a decision and manually dispelled them.

Immediately, more waves of experience and memory flowed into his mind. Haruki took his time to savor the data.

Once all of it had been integrated, he checked his panel again.

This time, Genjutsu: Sharingan's proficiency had increased by 50 points—again, roughly two-thirds efficiency.

Haruki nodded in satisfaction.

Then he walked over to one of the Iwagakure corpses nearby and activated Chakra Absorption Technique, draining the remaining chakra to replenish himself.

Refreshed, he once again cast Shadow Clone Jutsu, creating four new clones and launched into another round of training.

Thus, every fifteen minutes, Haruki would reset the clones to keep their chakra and mental state fresh, repeating the cycle over and over.

Time passed swiftly.

An hour and a half later—

After fusing the latest batch of shadow clones' Rasengan experiences, Haruki saw that his Rasengan proficiency had reached Lv1 (197/200)!

Worried about a potential bottleneck at the level-up threshold, Haruki paused training Mind Reflection Technique and personally practiced Rasengan three full times.

As expected, it broke through instantly—Rasengan was now Lv2.

With the breakthrough, Haruki's understanding of Rasengan deepened significantly. Now, when he formed the jutsu, both speed and chakra density had clearly improved.

However, reaching the point where he could infuse Wind Release chakra into it to create the S-rank technique Wind Style: Rasenshuriken was still a long journey ahead.

But Haruki wasn't in a rush.

After all, he had yet to master both the shape and nature transformations of Wind Release chakra. Even if his Rasengan level increased, it wouldn't be enough to properly integrate Wind-style chakra just yet.

"Step by step, no need to force it."

Muttering to himself, Haruki shook off distractions, re-cast Shadow Clone Jutsu, and sent four more clones into the same training cycle.

Time flowed like sand through fingers.

Soon, another hour passed.

With the three-hour limit approaching, Haruki finally completed the training goals he had set.

Out of 200,000 chakra points:

28,000 were used on Mind Reflection Technique, yielding 180 proficiency points.

150,000 were used to train Rasengan and Genjutsu: Sharingan, boosting their proficiencies by 360 and 600 points respectively.

The remaining 20,000 chakra points were consumed by frequent use of Shadow Clone Jutsu.

To be honest, seeing that much chakra burned away made Haruki wince.

But he had no choice—time was limited, and results were critical.

Haruki stood up, glanced at the Iwa ninja corpses scattered around, then formed seals and activated Fire Style: Great Fireball Jutsu.

BOOM!

Scarlet flames roared forth, consuming every corpse within seconds.

The smell of charred flesh hit him hard.

Haruki grimaced, covered his nose, and stepped back a few paces. Once the bodies had been reduced to nothing but ashes, he turned and left the area.

Not long after he left—

A group of ten Iwa ninjas arrived, escorting two medical-nin.

Clearly, they had been assigned to retrieve and treat the wounded in this sector.

But what greeted them was a field of charred remains.

Their expressions darkened immediately.

Some grew visibly tense, others alertly scanned the area, or reported the incident to their superiors, while others began searching for any enemy traces.

A full-scale investigation was launched in an instant.

But by the time they found any hints, Uchiha Haruki had already chosen his next target.

This time, it was a four-man team rushing through the woods. No clue where they were headed.

Haruki trailed them cautiously.

After confirming that no one else was nearby and that all four were merely chunin, he struck without hesitation.

In a few quick moves, he had subdued all four.

Then, without delay, he activated Genjutsu: Sharingan, probing the mind of the leading Iwa chunin to retrieve intel about their mission.

It didn't take long for Haruki to understand the purpose of their assignment.

They were couriers, carrying classified information.

As for the contents—

Haruki pulled open the lead ninja's uniform and retrieved a scroll hidden in his inner pocket. But when he saw the sealing tag affixed to it, he abandoned the idea of opening it.

These kinds of scrolls had self-destruction seals unless unsealed properly—which these disposable couriers most certainly didn't know how to bypass.

So Haruki didn't waste more time.

Scanning the surroundings, he used Shadow Clone Jutsu to create a new clone. Then, with the help of that clone, he dragged the four captives to a secluded corner.

Once hidden, Haruki ordered the clone to stay alert while he prepared for training.

Based on past experience, if he fully drained them, these four chunin could probably provide around 30,000 chakra points.

And this time, he wasn't in a rush.

He could funnel all of it into training Mind Reflection Technique, earning upwards of 180 proficiency points.

Actually, if he wanted to maximize efficiency, he would've stayed put in one location and focused solely on training like he had the other day.

He could've let shadow clones go out and capture prisoners, slowly siphoning off their chakra over time, which would allow him to fully exploit each target.

That approach wouldn't waste time or resources.

But in the current situation, remaining in a single place was too dangerous.

So he had no choice but to abandon that plan for now.

Thankfully, with Iwagakure mobilizing over ten thousand ninjas to trap Third Raikage and his elite Cloud forces, the battlefield was chaotic.

Even a well-trained army had gaps during mass deployment, and Haruki could easily find new prey amidst the confusion.

He shook his head and pushed those stray thoughts aside.

Calming his mind, he turned his focus inward—fully immersing himself in the feedback of Mind Reflection Technique taking effect.
