Konoha's Tatsuya

"Yikes! Tatsuya-san, what happened to you?"

The next day, when Kyoko Akimichi opened the door and walked over to Tatsuya, she let out a gasp.

Seeing Tatsuya lying on the bed, looking sickly, Kyoko's mouth fell open in disbelief.

She remembered that he'd seemed much better yesterday. How could he have deteriorated after just one night of rest?

"Tatsuya-san, wait here, I'll go get a doctor!"

With a flash of panic on her face, Kyoko turned and ran out.

On the bed, the weakened Tatsuya raised his hand, but before he could even utter a word, Kyoko had disappeared.

Tatsuya let out a wry smile, accepting his fate.

Last night, after discovering that he'd transmigrated with the chip – his cheat – he'd been overcome with excitement.

After recording the information on the Transformation Technique, ignoring the intense fatigue setting in, he'd rummaged through his house and found a scroll for the Clone Technique, which he also attempted to record.

The result? A disaster!

Halfway through recording the Clone Technique, Tatsuya felt like he was about to collapse!

Both his mental and physical energy felt completely drained.

He'd gritted his teeth and persevered, managing to record the entire Clone Technique, but he was left on the verge of a complete breakdown.

After a night's rest, Tatsuya could barely muster a fraction of his usual energy.

Ten minutes later, Kyoko returned with a medical ninja wearing a Konoha forehead protector.

"Hayakawa-sama, please take a look at Tatsuya-kun!"

Arriving at the bedside, Kyoko pointed at the weakened Tatsuya and urged anxiously.

"Don't worry, let me take a look!"

Shun Hayakawa, a chunin from Konoha's medical team, gently reassured Kyoko, then sat down beside the bed to examine Tatsuya.

After a short while, Hayakawa looked up at Tatsuya and asked, "Tatsuya-kun, your chakra is severely depleted. Have you been practicing ninjutsu despite your injuries?"

"Chakra depletion? Hayakawa-sama, are you sure you're not mistaken?"

Kyoko, standing nearby, was bewildered and couldn't help but ask.

She and Tatsuya were childhood friends, and she knew his personality well. He wasn't the type to train so relentlessly!

"This is definitely chakra depletion. I wouldn't make a mistake about that," Hayakawa replied, a hint of displeasure on his face.

"Hayakawa-sama, you're absolutely right. I was practicing the Transformation Technique last night and didn't pay attention, causing my chakra to become depleted!" Before Kyoko could say anything else, Tatsuya quickly interrupted, speaking with a touch of embarrassment.

"Depleting your chakra by practicing the Transformation Technique!" Hayakawa's mouth hung slightly open, his expression utterly strange.

He was shocked by Tatsuya's answer.

The Transformation Technique was a basic ninjutsu taught at the Ninja Academy, one of the skills tested during Konoha ninja graduation exams.

For a full-fledged Konoha genin to exhaust his chakra by practicing the Transformation Technique!

Just how inept did someone have to be for that to happen?

Hayakawa couldn't comprehend it.

"Excessive chakra depletion can have a significant impact on your body. Your injuries haven't fully healed yet. Be more careful when practicing ninjutsu in the future."

However, to avoid damaging the young man's self-esteem, Hayakawa held back. He didn't say anything more, simply giving Tatsuya a few words of advice before hurrying away.

After Hayakawa left, Kyoko remained in the room, silently shaking with suppressed laughter, her shoulders heaving.

Tatsuya rolled his eyes, forced to endure Kyoko's silent mockery.

He was also incredibly frustrated.

Who could have guessed that the advanced technology of a biometric chip would adhere to the local customs, using chakra as its energy source?

In the blink of an eye, a month and a half quickly passed.

After this period of recuperation, Tatsuya's body had finally recovered.

Whoosh...

Inside the room, Tatsuya left the bed and stood in the center of the room. He let out a soft breath and formed hand seals.

Poof!

White smoke billowed in the room, and an identical figure appeared beside Tatsuya.

The Clone Technique was a success!

Looking at the clone beside him, Tatsuya smiled.

After a morning of practice, he had finally mastered both the Clone and Transformation Techniques.

Although the Clone and Transformation Techniques were basic ninjutsu taught at the Ninja Academy, some ninja graduated without mastering them.

The previous Tatsuya Akimichi had been one such ninja.

If it weren't for the outbreak of the Third Shinobi World War, Tatsuya would probably still be a high-age student at the Ninja Academy.

Therefore, as soon as his body recovered, Tatsuya couldn't wait to test it out.

Just as he'd suspected, after the biometric chip recorded and stored the information, Tatsuya's understanding of the methods and techniques for using the Clone and Transformation Techniques deepened significantly.

The principles and techniques of the Clone and Transformation Techniques were etched into his mind like engravings; the only thing lacking was physical proficiency.

With enough practice, Tatsuya could perfectly and skillfully execute them.

With the cheat function of the biometric chip, Tatsuya's ninjutsu learning talent would far surpass that of most other ninja.

No matter what kind of ninjutsu, as long as he had the ninjutsu learning scroll, Tatsuya could quickly learn it.

However, the chakra consumption of the biometric chip during the first recording of ninjutsu data was very high. With Tatsuya's current chakra levels, he couldn't yet record some of the more advanced ninjutsu.

Tatsuya didn't want to end up bedridden for another two weeks due to excessive chakra depletion.

To learn more advanced ninjutsu, Tatsuya had to first increase his chakra reserves.

Having figured this out, Tatsuya rested for a while. Once his chakra had recovered, he began practicing chakra extraction techniques for the first time since arriving in this world.

Chakra was the product of evenly mixing a ninja's spiritual energy and physical energy.

In the ninja world, chakra was the foundation of all ninja power. Whether it was ninjutsu, genjutsu, or taijutsu, chakra was needed to maximize their power.

The principle of chakra extraction was simple, but the actual results varied from person to person.

At the Ninja Academy, the teacher had taught all the students chakra extraction techniques. However, Tatsuya's aptitude was poor, and his understanding and comprehension of the techniques were shallow. He hadn't fully mastered them.

Following the memories in his mind, Tatsuya began to circulate the chakra extraction technique.

"Unknown ninjutsu detected. Store data?"

After circulating the chakra extraction technique once, the pleasant female voice immediately sounded in Tatsuya's mind.

"Store."

Without any hesitation, Tatsuya chose to store it.

Tatsuya hadn't expected the biometric chip to be able to record ninjutsu he had already learned.

"Chakra Extraction Technique stored. Flaws detected. Optimize?"

"Optimize."

Seeing the optimization option pop up in his mind, Tatsuya excitedly and quickly selected it.

"Chakra Extraction Technique optimization in progress. Estimated time: nine days. During optimization, the chip will continuously consume the host's chakra. Please refrain from excessive chakra use. During optimization, the biometric chip cannot record other data."

Along with the sweet female voice, Tatsuya keenly felt his chakra begin to deplete continuously.
