Naruto: Starting with Creating a Genius Persona

The treatment continued for quite some time, and when the green light at Tsuna's fingertips slowly faded, the hideous wound on Shinichi's right arm had disappeared.

The newly formed skin still had a faint pink hue, and the muscle texture had returned to normal. Although it was still weak and powerless and needed a long period of rest to recover its function, the sense of continuous damage and the strange injuries had been completely eliminated.

"The toxins in the wound have been cleared, and the basic repair is complete. The rest depends on your own recovery. Given your constitution, you should be able to move around after resting for half a month. However, remember, you are not allowed to engage in any high-intensity ninjutsu training or taijutsu training within a month, otherwise you will suffer from hidden injuries, which will be a real pain for you on rainy days in the future."

Tsunade withdrew her hand, her face still somewhat pale, her forehead damp with sweat, but her eyes were much clearer than when she arrived. After speaking, she didn't even look at Shinichi, and turned to walk towards the door.

Tsunade opened the door and paused for a moment when she saw the Third Hokage and the Monkey King standing there.

"Old man," she greeted him, her tone flat and devoid of emotion.

"Thank you for your hard work, Tsunade," the Third Hokage said gently, his gaze lingering for a moment on her still somewhat pale face.

Tsunade avoided his gaze, simply waved her hand, and walked straight to the other end of the corridor, her back straight and her steps quick, as if she was eager to leave this place.

The Third Generation saw her off until her long golden hair disappeared around the corner before turning his gaze back to the ward.

On the hospital bed, Shinichi was trying to gently move the fingers of his newly reattached right hand. His face showed no particular expression, neither the relief of surviving a disaster nor the worry about his injuries. He was so calm that he didn't seem like a boy who had just recovered from serious injuries.

"How are you feeling, Shinichi?" The Third Generation walked into the ward, his voice steady.

"I'm much better now, Hokage-sama. It's all thanks to Tsunade-sama," Shinichi replied politely, his tone respectful.

The Third Hokage nodded, sat down in the chair beside the hospital bed, and after a moment of contemplation, slowly spoke: "The Monkey King has already told me in detail about the new technique you developed, the Great Flame Rasengan. Its power is astonishing, but the risks are also extremely high. Until you find a way to fully control it or eliminate its backlash, I forbid you from using it lightly again. This is not a suggestion, it's an order! Your future is more important than an unfinished technique, understand?"

Shinichi met the Third Hokage's serious gaze, remained silent for a few seconds, and then slowly nodded: "Yes, I understand, Hokage-sama."

His obedience was without hesitation, but the Third Generation saw a flicker of an unextinguished flame deep within those calm eyes.

He knew that the boy's understanding might just be a temporary period of dormancy.

After giving a few more words of advice to rest and recover, the third generation got up and left.

As Hokage, he still had many matters to attend to.

The ward returned to silence. Shinichi leaned against the headboard, gazing at the snowflakes falling again outside the window, lost in thought.

.........

Two weeks later, it was deep winter.

The snow had not yet melted at Konoha's fourth training ground, and the air was crisp and cold.

The Ape Demon King crossed his arms and looked helplessly at the black-haired boy in the center of the arena who was moving his limbs and whose breathing had returned to normal.

Beside it, the Third Hokage, Hiruzen Sarutobi, draped in a divine robe, stood quietly, his gaze gentle yet scrutinizing.

Shinichi's recovery speed exceeded Tsunade's expectations, but as soon as his injuries stabilized, he couldn't wait to throw himself back into training.

After a well-controlled sparring session with the Monkey King, combining taijutsu and ninjutsu, he then attempted to perfect the Great Flame Rasengan.

Knowing the danger of the technique's backlash, the Monkey King couldn't dissuade him, so he simply invited the Third Hokage, who was taking a break recently.

With the Third Hokage present, they can at least cover the worst.

"Shinichi." The Third Hokage looked at the boy approaching, not giving a direct order or reprimand, but like a teacher guiding a disciple's thinking, calmly asked, "Are you in such a hurry to try again because you've come up with a solution to the backlash problem?"

"Yes, Third Hokage." Shinichi bowed respectfully, then nodded frankly. "For the past two weeks, I've repeatedly recalled the details of my injury and figured out the cause. The Rasengan itself is a highly compressed and violently rotating ball of chakra, which is inherently unstable."

"The Great Flame Rasengan is forcibly infused with fire-style chakra, which is known for its violence. The combination of the two amplifies its power, and the energy within it becomes extremely violent. At the moment of impact and energy release, the violent feedback directly impacts the user's arm that maintains the chakra form, causing severe erosion and tearing."

He paused, then continued, "So, the simplest idea is to prevent it from exploding directly in my hand. If I can throw it safely, like a kunai shuriken, and have it explode far away from me, then the problem of backlash can be solved."

The Third Hokage nodded slightly: "Throwing it out to avoid direct contact damage is indeed the right approach. It's one of the common strategies for dealing with the backlash of such close-range burst ninjutsu."

But then he changed the subject, pointing out the key difficulty: "However, Shinichi, the problem lies in safe throwing. Even a regular Rasengan is difficult to maintain its shape after leaving the body, let alone the Great Flame Rasengan, which is infused with violent fire attribute and is extremely unstable. It's like a lit fuse, but an extremely sensitive explosive. You have to do your best to maintain it in your hands to prevent it from exploding prematurely. Once it leaves your hands, it will probably explode on the spot because it's out of control, as soon as it's out of your continuous chakra control and shape maintenance."

The Monkey King said in a deep voice, "Hiruzen is right. Kid, the idea is good, but it's too difficult to execute. Once that thing leaves your hands, it's just a firecracker that explodes at the slightest touch; it won't fly far at all."

"Yes, Third Generation Lord, Senior Monkey King, I have also pondered this question repeatedly."

Faced with the core dilemma pointed out by the Third Hokage and the Monkey King, Shinichi did not show any discouragement or confusion; instead, he nodded.

"That's why I thought of another approach. Since the backlash of the Great Flame Rasengan stems from its extreme compression, rotation, and the combination of its violent fire attribute, making the technique difficult to control and extremely unstable, could we take a step back, retain the Rasengan's core advantages of rapid and highly concentrated chakra, but appropriately reduce the degree of concentration while completely eliminating the rotational characteristic that exacerbates instability?"

"Like this!"

Before he finished speaking, he had already raised his right hand, his five fingers spread wide.

Without any complicated hand seals or even obvious violent fluctuations in chakra, a blazing and solid crimson flame, as if tamed by an invisible force, suddenly appeared in his palm!

This flame was neither as expansive and outward as a typical fire jutsu, nor as violently rotating and compressed to the extreme as the Great Flame Rasengan.

It is more like a highly concentrated, stable, solid core of flame, devoid of excess agitation, burning quietly and emitting scorching yet orderly energy fluctuations.
