New Captain!

Rasengan, an A-rank Ninjutsu that requires no hand seals!

Knowing the specific training method, Gong Yi quickly made the necessary preparations.

Balloons and rubber balls were easily purchased in bulk.

Injecting water into a balloon, Gong Yi attempted to circulate his chakra, accelerating it to burst the water sphere.

He spent almost no effort on this step, completing it in no time.

Next, he injected water into a rubber ball. Holding it in one hand, Gong Yi followed the training method used by Naruto Uzumaki, controlling his chakra to rotate in a single direction.

As the rotation speed increased, it grew faster and faster.

Bang!

The rubber ball burst!

OK, the second stage was also cleared with ease.

Gong Yi's eyes narrowed slightly. Next is the third stage, which is also the most important one!

Extending one hand, he gathered chakra in his palm, circulating it from slow to fast in the same rotational direction as before.

A spiral-shaped sphere of chakra gradually took form.

Just as Gong Yi was feeling pleasantly surprised, his chakra suddenly spiraled out of control. With a loud bang, both of his hands were left dripping with blood.

"It's a bit dangerous, but it's of no consequence!"

Gong Yi's mind stirred, and he cast the Healing Technique. His injured hands quickly recovered to their original state, leaving no trace of damage.

"If I only had the low-level Recovery Technique, training the Rasengan would be quite perilous, but with the Healing Technique, I have nothing to worry about."

Gong Yi smiled and resumed his work.

Truth be told, training the Rasengan is not actually difficult.

Especially for someone with exceptional chakra control, this Ninjutsu is quite simple.

The only thing one needs to be mindful of is the damage caused during the training process.

Naruto Uzumaki supposedly learned the Rasengan very quickly, but in reality, he was using the cheat of Multi-Shadow Clone, possessed the formidable Uzumaki bloodline, and had access to the near-infinite chakra provided by the Nine-Tails.

However, if one combines these factors, Gong Yi's training of the Rasengan was even simpler than Naruto Uzumaki's.

With the Healing Technique at his disposal, his chakra could also be considered infinite during training.

He recovered from physical injuries even faster than Naruto Uzumaki.

Furthermore, when it comes to chakra control, Gong Yi is inferior to no one!

With over thirty points of mental energy and years of frugal chakra usage, his control over his chakra has reached its peak.

He had long since mastered exercises like tree climbing and water walking, facing almost no pressure at all.

Precisely because of this, even without the super-cheat of Multi-Shadow Clone for doubling experience, it didn't take Gong Yi long to master the Rasengan.

Five days!

Just five days—two days faster than Naruto Uzumaki in the original story.

Feeling the continuously rotating sphere of chakra in his hand, Gong Yi wore a smile. He could imagine, if he were to approach an enemy at high speed using his taijutsu, and then unleash the Rasengan, who could possibly withstand it?

He casually pressed the Rasengan against a rock, blasting an incredibly deep hole into it.

Clapping his hands, he didn't even bother using the Healing Technique to recover the consumed chakra, and slowly walked toward his house.

He had already completed half of his third research project: developing and mastering two forms of Ninjutsu shape transformation.

However, he was feeling a bit stumped regarding the second Ninjutsu transformation.

In developing the Rasengan, he had taken advantage of the experience provided by Naruto Uzumaki's training, but how was he to proceed with the second transformation?

"Sasuke Uchiha's Chidori is a shape transformation, but it is built upon Kakashi's Chidori. However, Chidori already involves nature transformation; with my current accumulation, I cannot conduct research in that direction without sufficient time."

"Besides, my affinity for Lightning Style is not high, making it difficult to imitate Chidori."

Gong Yi walked with his hands behind his back, lost in a dilemma.

"Forget it, it was lucky enough to benefit from the Rasengan. I shouldn't rush the second shape transformation. I'll first fully analyze the Eight Inner Gates and try to open two more gates. Also, I cannot neglect the training of the Spirit Refining Technique."

Gong Yi had a feeling that as he advanced his Spirit Refining Technique to a deeper level and his mental energy increased, his research into Ninjutsu would become much more convenient.

Perhaps, by then, the opportunity would arise naturally.

Just as Gong Yi was immersed in his training, Iga Kawaji walked into the Konoha Hokage building with a complex expression.

"Have you thought it through, Kawaji?"

"Lord Hokage, I have decided. I am resigning from my position as squad leader!"

The Third Hokage looked at the pained expression on Iga Kawaji's face and couldn't help but sigh.

"Regarding your squad, do you have any opinions on the candidate for the next leader?"

Just like when Sasuke Uchiha left Team 7 and Kakashi was severely injured in the original story, the Hokage would arrange for new members to join and appoint a new leader.

After all, the genin and chunin currently in their growth phase cannot be left without a captain.

Iga Kawaji seemed to have anticipated this, already having a plan in mind.

"Lord Hokage, I propose that Gong Yi be appointed as the squad captain!"

The Third Hokage was somewhat surprised. "Gong Yi is so young and lacks extensive mission experience. Isn't this proposal a bit reckless?"

Iga Kawaji shook his head. "Firstly, Gong Yi's strength is more than enough to qualify him for the role of captain."

The Third Hokage hummed in acknowledgment. After all, Gong Yi had ambushed and killed an entire squad of jonin; no one would believe it if someone claimed his strength was insufficient.

Iga Kawaji continued, "Secondly, can the village even spare more jonin right now to lead genin on missions?"

The Third Hokage furrowed his brows, unable to refute this.

The village might appear calm on the surface, but undercurrents were surging as they guarded against the small movements of Sunagakure and Iwagakure.

They truly could not spare much manpower.

Otherwise, he would not have assigned Iga Kawaji, who came from the Anbu, to lead Gong Yi and the others back then.

"Lastly, and this is what I consider most important!" Iga Kawaji took a deep breath. "Gong Yi is a child with a strong sense of initiative, and he can make accurate judgments when encountering danger. The fact that we were able to escape the Land of Rain was partly due to his contributions."

"I believe that a talent like him needs more training in leading squads independently. By the time war breaks out, he might be able to stand on his own!"

"Time waits for no one; there is no way to let them grow stronger in peace anymore!"
