Chapter 9: Trading Defense for Ultimate Offense

*The two different modes of the "Shinsoku" (Divine Speed) ability: either the conscious control of "Denkou Sekka" (Lightning Speed) or the instinctive, body-driven control of "Jifuu Jinrai" (Thunderstorm Blast).*

These two distinct modes are extremely useful for Sasuke. Although it lacks a strong defensive capability, the extreme speed gained in return is something that the lightning-style chakra mode of Kumogakure (Hidden Cloud Village) cannot even compare to. For Sasuke, the best defense is offense. Therefore, sacrificing defense to gain stronger attacks and greater speed is a completely worthwhile trade-off.

As soon as an idea arose in his mind, the ninjutsu laboratory immediately captured it.

*[Host's idea captured]*

*[Simulation in progress]*

This time, once again, a small figure formed from energy could be seen performing various movements in front of Sasuke. Inside his body, the energy representing lightning continued to flow. The small figure appeared and disappeared as if the simulation had failed. However, after several consecutive attempts, the lightning within the figure began to increase.

Seeing this, Sasuke felt a bit excited. However, during the entire process, he didn't realize that time was slipping by quickly. Time in the ninjutsu laboratory was difficult to perceive, and now it was flying by. In the blink of an eye, an hour and a half of simulation had been reduced to just thirty minutes remaining.

*[00:32:18]*

The last thirty-two minutes.

By this point, the small figure had already failed more than a dozen times. Finally, it seemed to have succeeded.

*[Laboratory simulation complete]*

*[Would the host like to continue simulating to enhance this ninjutsu?]*

This time, it seemed only one solution had been simulated, and it still looked quite rudimentary. Sasuke carefully observed the small figure in front of him. It was surrounded by electricity, but the currents weren't very intense. In the next moment, the figure began to move rapidly. Its speed was so high that only a trail of electric light was visible in its wake.

Sasuke's eyes narrowed slightly. *This speed was truly impressive.*

After the figure moved back and forth a few times to showcase its speed, a red energy figure appeared. Immediately, the state of the electric figure began to change. The lightning on its surface appeared to have a wider range now.

Soon after, the red figure attacked. However, before it could even finish its movement, the electric figure countered instantly. Its attacks were as fast as lightning, hitting the red figure five or six times in a split second.

"Jifuu Jinrai?" 

"Earlier it was Denkou Sekka." 

"Has it really been simulated?"

Sasuke was thrilled. However, glancing at the clock, he was surprised:

"How are there only thirty-two minutes left?" 

"Has over an hour already passed?" 

*[Would you like to continue the simulation to enhance this ninjutsu?]*

Continue simulating? If he did that, there wouldn't be enough time.

"No! Inject it directly!" 

With only thirty minutes remaining, Sasuke wasn't sure if there would be enough time. He started to grow impatient.

*[Assisted training mode activated]*

*[Please name the ninjutsu]*

"Raiton – Shinsoku!" 

*[Assisted training in progress: Ninjutsu "Raiton – Shinsoku"]*

In the next moment, that familiar sensation returned. Violent chakra began flowing automatically within Sasuke. At the same time, his Sharingan, which had been inactive, was automatically activated.

Apparently, both Chidori and Shinsoku required the assistance of the Sharingan. Lightning-style techniques, though powerful, were inherently difficult to control, making the Sharingan's support understandable.

As the chakra continued to flow incessantly within Sasuke, "Raiton – Shinsoku" was also a ninjutsu that did not require hand seals to activate. Sasuke felt the flow of chakra in his body while watching the time pass quickly. He had the impression that the chakra had only just started flowing, yet ten minutes had already passed. He wondered if the remaining time would be enough to fully master Shinsoku.

While Sasuke was still worried, the first form of Shinsoku, **Denkou Sekka** (Lightning Speed), was successfully simulated.

The intense pain left Sasuke with no room to worry about time.

Zzzzzt!

Suddenly, Sasuke's eyes snapped open, and an astonishing surge of lightning erupted from his crimson two-tomoe Sharingan.

In the next moment, his entire body was enveloped in lightning. Even his hair took on a shape resembling lightning bolts.

Above his head, a lightning symbol seemed to appear.

The lightning covering his body wasn't like the explosive chakra seen in the Lightning Chakra Mode. Instead, it emitted thin, delicate arcs of lightning.

In the darkness, Sasuke would be easily spotted, as the edges of his body occasionally sparked with bursts of electricity.

With Denkou Sekka activated, Sasuke felt that his speed had increased by far more than just one level.

However, a new issue emerged.

Sasuke noticed that his chakra consumption rate wasn't just high—it was alarmingly fast.

He realized he couldn't sustain this form for even a minute before completely depleting his chakra.

"My chakra reserves... are pitifully low!"

If he had a physique as abnormal as Naruto's, combined with the power of Shinsoku, Sasuke believed he would already be on par with Kage-level shinobi.

But it wasn't over yet. The training to master the second form of Shinsoku, Jifuu Jinrai (Thunderstorm Blast), had begun.

The flow of his chakra began to shift. Sasuke glanced at the clock.

"Only five minutes left?"

"That's not enough time... is it?"

As Sasuke worried, his chakra flow rapidly completed the transformation.

*Denkou Sekka* and *Jifuu Jinrai* were both forms of Shinsoku just two different applications.

Once *Denkou Sekka* had been simulated, the simulation of *Jifuu Jinrai* posed little difficulty, requiring only slight adjustments to a few key elements.

With just one minute left on the countdown, Sasuke successfully completed the simulation of *Jifuu Jinrai*.

Finally, Sasuke let out a deep sigh of relief.

"It's done!"

[Ninjutsu: Raiton - Shinsoku]

[Assisted training completed]

[Would you like to proceed with a second round of assisted training?]

As the system posed its question, time ran out.

Whoosh!

Before Sasuke could answer, his consciousness was directly pulled out of the simulation.

Back in his room, Sasuke glanced around briefly, unable to do much else.

In the next moment, a wave of intense exhaustion washed over him, and he fell fast asleep.
