As Saitama gazed out at the increasingly dark sky outside, his expression shifted to something that shouldn't appear on a child his age. The weight of knowledge and purpose settled over his small shoulders like an invisible mantle.
Saitama's transmigration wasn't accidental—it was an inevitable event that had been carefully prepared. The strongest talent promised by the great deity before his journey through time was finally ready to be fulfilled!
The strongest talent most suitable for him, a talent that constantly improved and adapted—this was the "Golden Finger" that Saitama had obtained through his transmigration across worlds!
Previously, because he was still too young, Saitama hadn't wanted to get involved with ninjutsu too early. That's why he had never studied the ninja legacy left behind by his deceased parents, despite having access to it all along.
It's better to seize the moment than wait for the perfect day. Let's experience the magical ninja world today!
With this thought burning in his mind, Saitama could no longer contain his fiery enthusiasm.

The Sacred Repository
Rising from his cushion, Saitama walked out of the room and headed upstairs, his bare feet silent on the polished wooden floors.
The house had three stories, each serving a distinct purpose. The first floor contained the kitchen, living room, a storage room piled with various sundries, and the guest room where Grandmother Kaori now lived. The second floor housed Saitama's residence along with several additional guest rooms that had remained empty since his parents' deaths. But the third floor held the true treasure: some of his parents' ninja heritage, ninjutsu scrolls, and accumulated experience from years of shinobi service.
Originally, Grandmother Kaori had lived on the second floor with Saitama, which had been convenient for taking care of him when he was younger. However, as Kaori felt her body wasn't as strong as before and Saitama had become more independent, she had moved to the first floor. The change made travel easier for her aging joints while giving them both the space they needed.
Climbing the stairs to the third floor, Saitama stopped in front of a particular door. This entrance was thicker than all the doors downstairs, and it was obvious at first glance that important items were stored inside.
Taking out the key from under the carpet beside the door, Saitama unlocked the heavy barrier and stepped inside.
The air was filled with the rich scent of ink and aged books, yet there was no musty smell that typically accompanied long-abandoned spaces. This was because Saitama came to clean the room every few days, maintaining its pristine condition even though he had never seriously studied the materials stored here.
Although he hadn't formally learned from the treasures kept in this room, Saitama still made sure to flip through them from time to time, familiarizing himself with their contents through casual browsing.
Turning on the light and gently closing the door behind him, Saitama skillfully opened a scroll on the desk, sat down, and began reading it slowly and carefully.
Looking at the cover of the scroll, elegant calligraphy proclaimed: "Chakra Refinement Technique"

Understanding the Foundation
Following along with the text, what Saitama was examining was indeed a volume dedicated to chakra refinement technique!
What were the essential elements needed to evaluate a ninja's capabilities? Wasn't it chakra above all else?
At least, Saitama firmly believed that chakra represented the natural barrier separating ninjas from ordinary people! With chakra flowing through your body, you were no longer just another civilian.
But where did chakra originate from?
From the scroll in his hands, Saitama absorbed crucial information, and combined with memories from his previous life, he identified the three fundamental components that comprised chakra.
The first component, as recorded in the scroll, came from the human body's one hundred and thirty trillion cells, each possessing the ability to store and manufacture chakra. The chakra refinement technique he now held detailed precisely how to extract and utilize the energy contained within these cellular structures.
The second component was spiritual power, while the third consisted of natural energy!
Currently, the only type that Saitama could access and employ was the first—chakra extracted directly from his body's cellular matrix!
Saitama had read through this particular chakra refinement technique no fewer than ten times, and the content within had become intimately familiar to him. With his excellent memory, he had long since memorized all the essential points of the chakra refinement process, yet he had never attempted to actually practice the technique until this moment.

The First Extraction
After slowly reading through the scroll in his hands once more, Saitama carefully reviewed everything again in his mind, ensuring he had missed no critical details.
After confirming that nothing had been overlooked, Saitama returned the scroll to its proper place and seated himself cross-legged on the tatami mat beside the desk.
Due to his frequent cleaning routine, Saitama naturally hadn't neglected the tatami in this room, so the woven surface still carried the fresh scent of recent washing.
Sitting in the traditional meditation posture, Saitama slowly relaxed his entire body, allowing himself to reach the state of "Zen" mentioned in the scroll's instructions.
Everything fell into perfect silence, and Saitama's heart gradually calmed to a state of peaceful equilibrium.
He began to imagine that infinite energy existed within his body, flowing like countless invisible streams through every fiber of his being.
Though there was no wind stirring the air in the room, Saitama, sitting cross-legged in meditation, felt traces of warm currents flowing across his entire body.
The sensation was pleasantly warm, like winter sunlight shining on a slightly chilled body, bringing comfort and vitality!
Could this be chakra?
Saitama's mind filled with surprised delight. This was the first time he had truly come into contact with this wonderful energy, and an indescribable feeling rose in his heart—something he couldn't quite put into words but knew was profoundly significant.
Although he understood that his talent was exceptionally strong, actually extracting chakra proved to be an entirely different matter from theoretical knowledge.
Following the method described in the scroll, Saitama guided the mysterious "wind" with his focused will, slowly directing it toward the dantian located in his lower abdomen.
The lower abdomen's dantian served as the primary storage location for chakra. All freshly extracted chakra needed to be carefully guided to circulate through this central point.
The advantage of this process was that it could adapt chakra to follow such a specific route—essentially establishing a predetermined pathway for the newly born chakra and preventing it from wandering aimlessly throughout his system. This foundational circulation would prove crucial for all future chakra manipulation techniques.
A thin stream of chakra was slowly guided into Saitama's lower abdomen, settling into the dantian like glowing embers finding their proper hearth.
This marked Saitama's first genuine step into the ninja world, and it was also a truly historic first step that would define the trajectory of his entire future.
