Naruto The Red Spiral Rebirth

On the evening of his meeting with Mr. Kakashi, Tom invited him to have some barbecue. As soon as the two sat down, Kakashi returned a small notebook to him.

"Tom, you dropped this during the day. So careless!"

"Ah, thank you, Mr. Kakashi! If I had lost this diary, I really wouldn't know what to do. It's very important to me!" Tom pretended to be completely unaware and expressed his gratitude repeatedly.

"Also, Ms. Kakashi, please look after Naruto. That guy's a single-celled organism—he doesn't know how to think for himself."

Kakashi chuckled. "Haha, Naruto really is simple."

The two talked for quite a while, but eventually the mood became more serious.

Tom took the initiative to say, "Mr. Kakashi, if you're staying in the village for a while, I'll go take on some other tasks. I haven't done anything besides this mission for a long time."

Kakashi nodded. "Alright. When it's time to leave the village again, I'll have Parker notify you."

"Then I'll count on you," Tom replied, bowing deeply out of respect.

In the days that followed, Naruto and his team continued doing D-rank missions in the village. Meanwhile, Tom began practicing the Rasengan (Spiral Pill) based on memories from his past life, all while guiding Hinata in her Taijiquan training.

If there's one thing a transmigrator in the Naruto world must do—aside from eating and sleeping—it's to practice the Rasengan.

The Rasengan was originally created by the Fourth Hokage, Minato Namikaze, after observing the power of the Tailed Beast Bomb. It was later taught to Jiraiya, who passed it on to Naruto. Eventually, Naruto taught it to Konohamaru. Over time, Naruto developed enhanced versions like the Giant Rasengan, Sage Art: Massive Rasengan, and ultimately the Rasenshuriken.

The Rasengan is a technique that condenses chakra into a sphere in the hand, making it spin and compress in different directions to form a high-density ball of energy.

Training in Rasengan can be divided into four main stages.

---

Stage One: Chakra Gathering

In the first stage, the goal is to gather chakra into the palm. Tom had already achieved this through his practice with Hinata while developing Taijiquan. However, the Rasengan requires concentrated chakra for destructive force, whereas Taijiquan needs even distribution for perception.

---

Stage Two: Steady Chakra Output

This stage involves releasing chakra steadily and continuously. As described in the original manga, one method is to fill a water balloon and hold it while releasing chakra, making the water swirl irregularly until the balloon bursts.

Tom practiced for a full day. He was eventually able to make the water in the balloon rotate in one direction. But getting it to rotate in multiple directions simultaneously was another story. Either the chakra flow would become unstable or break entirely. The difficulty wasn't gathering or outputting chakra, but rather making it rotate unpredictably while maintaining flow.

"Do I really have to do it like Naruto—twisting the chakra with my hands? That's too frustrating…"

The Shadow Clone Solution

On the second day, Tom used the Multi-Shadow Clone Jutsu.

This was his cheat code.

Shadow clones are incredible for accumulating experience and sharing it back to the original upon dismissal. If Tom wanted to avoid the physical twisting Naruto used, he would need to learn how to divide his attention and multitask—a crucial step in manipulating chakra in several directions.

To train his multitasking ability, he borrowed inspiration from the martial arts novel The Return of the Condor Heroes. In it, the monk Reverend Yideng teaches the protagonist how to draw a circle with one hand and a square with the other—perfect for developing split attention.

After a few days, Tom could do this exercise effortlessly. With the help of his shadow clones, he needed just ten days to master this skill. By then, he had completed the second stage of Rasengan training.

---

Stage Three: Chakra Compression

The third stage is to maintain steady chakra output while compressing and shaping it—just like bursting a balloon, but now with a rubber ball.

According to Jiraiya in the original story, a rubber ball is 100 times tougher than a water balloon. Since there's no water inside, Tom had to focus his chakra even more intensely, compressing it into a denser, materialized sphere.

This stage only allows the Rasengan to damage the outer surface of things. It can't yet penetrate rocks or trees.

To train for this, Tom again turned to inspiration from The Return of the Condor Heroes. He remembered how the character Xiao Longnü could sleep suspended on a rope, keeping balance by using small muscle groups throughout her body to maintain equilibrium. Tom mimicked this approach, applying that kind of fine-tuned control to chakra manipulation.

Once he understood the principle, progress accelerated.

After about a month of focused training using shadow clones and mindfulness techniques, Tom could maintain a continuous output of chakra and control its irregular rotation.

---

Stage Four: Solidifying Chakra

The fourth and final stage was the most difficult—solidifying the chakra while sustaining its motion and rotation. This stage is what gives the Rasengan its destructive power, able to bore into rock and splinter trees.

In the original story, Jiraiya used an inflatable balloon to restrict the size of the Rasengan, helping Naruto contain and stabilize the chakra.

But Tom decided to do the opposite.

Instead of forming a chakra sphere first and compressing it inward, he decided to control the external shape first and let the chakra stabilize inward from there.

He devised a creative solution using bricks.

Tom commissioned a batch of square clay bricks roughly the size of his palm. He hollowed out a cavity in the center of each brick the size of a Rasengan. Then, using finely controlled chakra—like an invisible scalpel—he carved swirling patterns inside the cavity.

This was meant to guide the chakra into a stable vortex.

Using this method, Tom attempted to channel chakra into the pre-carved cavity, dividing his attention to generate multiple vortex flows inside the space simultaneously.

It sounded simple.

It was anything but.

He went through nearly an entire cart of custom bricks before finally getting it right. The frustration was real.

"If I ever get the chance, I'm going to file a complaint about this technique," Tom muttered to himself with a scowl.

---

Final Success

Advanced ninjutsu like the Rasengan require not only power but intense chakra control. As the level increases, so does the difficulty in precision.

Eventually, Tom decided to divide his mind into three separate consciousness streams. One focused on chakra output, one on rotation, and one on containment. With this final approach, everything clicked.

Three months after he began training, Tom finally succeeded in completing the Rasengan.

He had officially mastered his first A-rank, non-seal (Muji) ninjutsu: the Rasengan.

At that very moment, far away on the village's outskirts, a bridge-building foreman named Tazuna was making his way toward Konoha, tired and worn out after a long day's journey.

The gears of fate were beginning to turn once more.
