Naruto: Reincarnated as Sasuke Uchiha with Perfect Talents.

Chakra moving uncontrollably within his body, flowing rapidly. 

This sensation was completely different from when he controlled his chakra himself. 

It felt as though the meridians in his body were about to tear apart. 

A sharp, intense pain surged through him. 

Sasuke's face turned bright red in an instant. 

While enduring the excruciating pain tearing through his body 

*Crackling!!* 

A burst of lightning suddenly erupted in Sasuke's hand, and lightning serpents coiled around his left arm. 

In the blink of an eye, a glowing sphere formed. 

The sphere, condensed from lightning, continuously emitted small sparks in all directions. 

It spread out like a spiderweb, extending rapidly outward. 

Looking at the lightning flashing in his hand 

**[Ninjutsu: Lightning Release ~ Chidori, successfully developed.]** 

**[Would the host like to re-enter assisted ninjutsu practice?]** 

"Assisted practice?" 

Was it referring to the earlier method where the system controlled the chakra flow within his body? 

Although it wasn't life-threatening, Sasuke didn't want to experience it a second time! 

The Chidori in his hand dissipated following the system's prompt. 

Sasuke recalled the chakra flow from earlier when the system took control. 

He had memorized its path and method completely. 

Could he attempt it on his own now? 

With this thought, Sasuke immediately started instinctively controlling his chakra, following the previously established flow. 

At first, it felt unfamiliar, completely unadapted to it. 

But gradually, as the chakra began flowing, Sasuke started to find the rhythm. 

The speed of the chakra flow increased, 

and the tearing pain quickly disappeared. 

*Crackle!* 

Lightning gathered in his palm. 

As streaks of lightning accumulated, only a few breaths passed. 

The lightning condensed. 

The sound of a thousand chirping birds filled the air, as though countless birds were calling all at once. 

Looking at the Chidori in his hand, joy flashed in Sasuke's eyes. 

**[Congratulations to the host for independently performing Lightning Release ~ Chidori for the first time.]** 

**[Would you like to use assisted ninjutsu practice to enhance control of this technique?]** 

He learned it in just one attempt. 

Looking at the system's prompt, Sasuke pondered. 

"Enhanced practice? Do I need system assistance?" 

Dismissing the Chidori, Sasuke immediately attempted it a second time. 

This time, the chakra flowed even more smoothly and quickly. 

Although no hand seals were required, maintaining the Sharingan was necessary, and the chakra flow had to remain stable. 

Otherwise, the release would easily fail. 

Sasuke noted the difficulty. 

Yet, for his current talent, it wasn't much of a challenge. 

A few more practice sessions should be enough to fully master it. 

However, releasing it uninterrupted during practice was one thing. In battle, there were countless variables. The enemy wouldn't simply stand by and let you perform ninjutsu. 

This aspect had to be considered. 

Even for a seal-less Chidori, more practice was needed for mastery. 

However, Chidori was an A-rank technique, and with Sasuke's current chakra reserves, he could probably only use it a few times in one battle. 

Two or three times was likely the limit. 

But as he grew more proficient, the chakra consumption would decrease. Furthermore, through consistent chakra refinement, 

his reserves would naturally increase over time. 

With steady, gradual improvement, he wouldn't have to worry about low chakra in the future. 

At this moment, Sasuke abruptly looked up at the laboratory's countdown. 

**[01:37:45]** 

Half the time had passed unknowingly. 

During this period, Sasuke felt as if only a few minutes had gone by. 

This realization surprised him. 

But he quickly snapped back to reality. 

Developing a seal-less Chidori had already consumed so much time. 

With only an hour and a half left, he needed to hurry. 

Practicing Chidori could wait until he left the laboratory. 

For now, Chidori could be set aside. The remaining time should be spent developing other techniques. 

Creating more Lightning Release techniques seemed unnecessary now. 

The laboratory's effects exceeded Sasuke's expectations. 

Using it to develop already-existing techniques felt like overkill. 

These could be learned through other means later. 

Instead, he should focus on creating techniques unique to this world. 

Bringing lightning manipulation methods from other worlds into this one. 

With this thought, 

scenes flashed rapidly through Sasuke's mind. 

Techniques with excessive power would likely be simulated by the laboratory, but learning and mastering them at Sasuke's current level was another matter. 

His limited chakra reserves were a significant constraint. 

Given his experience with the seal-less Chidori, this limitation was easy to understand. 

Speaking of seal-less techniques, Sasuke suddenly remembered another powerful Lightning Release technique. 

One this world had a version of 

The Fourth Raikage's **Lightning Chakra Mode!** 

But Sasuke wasn't thinking of using the laboratory to develop this mode. 

Instead, he thought of a technique from another world 

Killua Zoldyck's **Godspeed** from *Hunter x Hunter.* 

This technique had two additional applications: 

**Whirlwind** and **Thunderbolt.** 

Godspeed and Lightning Chakra Mode weren't the same. 

The Lightning Chakra Mode, as the Raikage's signature technique, 

focused on enhancing combat abilities, 

increasing speed, strength, and defense to terrifying levels. 

However, *Hunter x Hunter's* **Godspeed** 

was solely focused on speed. The concept of power in that world differed. 

While its defense and strength boosts didn't match the Lightning Chakra Mode, its pure speed translated into overwhelming power. 

The only drawback was the lack of defensive capability. 

Between the two, Sasuke preferred **Godspeed.** 

Moreover, **Godspeed** had two distinct usages: 

**Whirlwind**: controlled entirely by one's will. 

**Thunderbolt**: bypassing conscious thought, allowing the body to react instinctively to an opponent's moves, pursuing the ultimate speed.
