In the gentle morning sunlight, Sasuke completed his daily physical training, sweat soaking his clothes, but his gaze was resolute. He understood that to survive in this world full of unknown dangers, he must constantly push himself to grow stronger.

“One, two, three, four…” Counting steadily, Sasuke adjusted his breathing, feeling a surge of power stirring within him. Though only a little over a year old, his body was already far stronger than that of his peers, a testament to the relentless training he had undergone.

Reflecting on the past year—the chaos caused by the Nine-Tails, the Fourth Hokage’s sacrifice, the seal placed on Naruto—everything seemed surreal, like a vivid dream. In this time, Sasuke not only learned to speak and walk but also remained dedicated to his daily training. He knew that to thrive in a world where the strong reign supreme, he must first gain the power to protect himself. And to pursue the dream of becoming Hokage, he needed to master the power of chakra.

After completing his training for the day, Sasuke sat on the grass to rest. After all, he was still just over a year old and couldn’t exert himself too much. He realized that only by learning the method to extract chakra could he swiftly enhance his abilities. But how could he obtain this knowledge? Sasuke scratched his head in frustration. He had asked his brother Itachi for the chakra extraction technique a few days ago, only to be told he was too young to delve into such things. This left him both anxious and helpless, as he couldn't afford to appear overly eager.

Sasuke considered asking Uchiha Fugaku, but knowing his father’s unwavering dedication to the clan, he dismissed the idea. Sasuke didn’t want to reveal his potential, fearing that if his father knew, he would endure a childhood like Itachi's, which he found quite daunting.

Suddenly, Sasuke remembered that Itachi was out on a mission today. Seizing the opportunity, he quickly headed to Itachi’s room. He hoped to find the chakra extraction method there. Entering the room, his eyes scanned the space and eventually settled on a scroll lying quietly on a desk. A surge of indescribable excitement welled up within him as if he had found the key to the path of the ninja. He hurried forward and carefully unrolled the scroll—it was a basic ninjutsu manual!

“Haha! Heaven is truly on my side!” Sasuke couldn’t help but laugh, clutching the basic ninjutsu book tightly. This book was undoubtedly the key to unlocking the ninja world for him. Even if the Scroll of Seals were placed before him, it wouldn't compare to the practical value of this manual, especially given that he knew nothing in this new world. The sight of ninjas had once made him feel dejected for not being able to become one quickly, but now that he had the chance, Sasuke wasn’t going to let it slip away.

Suppressing his excitement, Sasuke carefully flipped through the pages, determined not to miss a single detail. As he read, several sheets of white paper fell from the book. Sasuke picked them up, unsure of their purpose, but decided to keep them in his pocket anyway. "Whatever they are, if Itachi kept them, they must be valuable."

After pocketing the papers, Sasuke continued to read the manual. Time passed, and as fatigue began to set in, he finally finished the book. His excitement grew, as the manual seemed perfectly tailored for him.

The book detailed the method of chakra extraction, the techniques of the basic Three Body Jutsu, and the formation of hand seals—each word resonated with him, igniting his blood and passion. This knowledge was both new and familiar, as if it awakened memories from his past life. He absorbed the information greedily, feeling as though every word contained boundless power.

Sasuke reread the manual several times to ensure he had memorized everything before returning it to its place. Back in his room, he formulated a clear plan. He understood that to become a true ninja, mastering chakra extraction was essential. "Chakra" was an energy born from the perfect fusion of spiritual and physical energies, used to perform ninjutsu, and could even be shaped into threads to bind or sever chakra-based substances.

Despite his physical exhaustion, Sasuke forced himself to stay awake, preparing to attempt chakra extraction. He sat cross-legged on his bed, closing his eyes to concentrate. Following the method described in the manual, he tried to draw energy from every cell in his body while focusing his mental strength. The process was arduous and slow, but Sasuke remained unwavering, holding on to his firm belief.

“Sasuke, what are you doing? Stop playing and come out for dinner,” his mother called from outside.

Her voice snapped Sasuke out of his trance. "What? It’s already evening? I’ve been extracting chakra for four hours, and I haven’t produced any yet. Oh well, I’ll eat dinner first and continue afterward. I refuse to believe I can’t extract chakra today."

After dinner, Sasuke returned to his room to resume his efforts. As time passed, he gradually felt a faint stream of energy coursing through his body—it was the chakra he had longed for! Carefully, he guided this power, allowing it to flow, gather, and grow stronger and more stable. When the first trace of chakra finally coalesced, a glimmer of joy flickered in Sasuke’s eyes. He knew this was only the beginning, but it was a crucial one that marked the start of his journey to becoming a ninja. Sasuke could almost see the moment he would stand as a powerful ninja, ready to carve his own legend with his hands and unwavering resolve.
