After over a year of researching chakra, drawing from both written sources and memories from his past life, Shiyu Uchiha concluded that ordinary ninja possess only one among the five elemental natures.
Having two or more was exceptionally rare. Possessing all five elements simultaneously was an extremely rare talent, appearing once in ten thousand. Shiyu had an instinctive feeling that perhaps the correct path for chakra cultivators lay in the synthesis of Water, Fire, Wind, Lightning, and Earth natures. However, lacking evidence, he could only keep this idea buried within.
As for Yin Release and Yang Release attributes, theoretically everyone possesses them.
Combining insights from both lives, Shiyu analyzed that the foundation of Yin Release is spiritual energy, whereas Yang Release originates from vital energy. As long as someone possesses chakra, they inherently have both Yin and Yang release, since chakra itself consists of spiritual and vital energies. Yet activating them, he believed, required one of two paths.
The first path involves quantitative change: when the ratio of spiritual to vital energy becomes unbalanced to a certain extent during chakra generation, corresponding Yin or Yang Release naturally emerges. This is how the majority of people obtain these attributes.
This type can be acquired later in life through exceptional chakra control and unique extraction techniques, although only either Yin or Yang Release can be obtained this way.
The second path involves qualitative transformation: once either vital or spiritual energy undergoes a fundamental transformation, the corresponding Yin or Yang chakra nature will inevitably emerge—and this form is far more stable.
For example, the Senju and Uchiha clans—descendants of Asura and Indra—are influenced by their bloodlines. Their inherent spiritual or vital energies exist in an incomplete transformed state from birth, further strengthening as their bloodline awakens.
Therefore, after the Senju integrated into Konoha, many inhabitants naturally possessed Yang Release, which laid the foundation for Konoha to develop the most advanced medical system in the shinobi world.
Shiyu believed that mastering both forms of Yin Release could unlock his potential for the ultimate Yin Release ability, although this remained just a hypothesis needing future verification.
Likewise, Shiyu speculated that combining Yin and Yang Releases into Yin-Yang Release would be no less powerful than the unified Five Elements Release—though still purely theoretical.
Suddenly struck by an idea, Shiyu wondered: If a member of the Uchiha clan continuously trained their spiritual energy without ceasing, upon reaching sufficient proficiency, would they awaken the Sharingan?
This thought excited him greatly—he felt a strong urge to try. Guided by a sound moral compass, he coveted the power of the Sharingan but refused to suffer its price. With rationality far outweighing emotion, it became nearly impossible to cultivate such intense suffering, especially since he refrained from investing genuine emotions into others. Without deep emotional attachment, where would excruciating pain come from?
Thus recently, Shiyu's enthusiasm for the Mental Meditation Technique intensified. After all, this was real tangible power—the kind capable of determining his own destiny.
That evening, Shiyu Uchiha was waiting in the dining room for dinner. Mikoto Uchiha had just returned and, upon seeing him, quickly stood up. She reached into the backpack beside her and pulled out a small pouch, saying, "Shiyu, here you go. This is your entrance gift." Then she gently ruffled his hair and smiled proudly.
Shiyu looked down at the present. It was an apprentice-level ninja pouch containing three unused kunai, ten shuriken, some senbon, and other items—all brand new.
What pleased Shiyu most was an additional tanto. Although it wasn't designed to channel chakra, its craftsmanship and quality were exceptional—clearly expensive. He couldn't help but feel thrilled about it.
Though he felt happy inside, his body instinctively responded, "Thank you, Onee-sama."
Privately, Shiyu guessed that this must have cost Mikoto quite a bit. Knowing how she never cared about saving money, he was sure she must've gotten extra funds from Uchiha Shizhi.
A bit touched, Shiyu took out the ninja tools from the bag and examined them carefully, genuinely delighted. If he'd had to buy them with his own meager allowance, it wouldn't have been enough—he'd even considered asking Mikoto for a small loan before.
Especially the tanto—Shiyu had always wanted to start training in swordsmanship. It felt like Mikoto had read his mind perfectly. As for the family swords, they were already honed to an incredibly sharp edge; Uchiha Shizhi would never allow him to touch them.
Delighted, Shiyu glanced at Mikoto and happily said, "Onee-sama, how did you know I needed a blade? I never mentioned it to you!"
Hearing that first thank you, Mikoto beamed proudly, like a queen surveying her kingdom.
But as Shiyu continued speaking, her face flushed slightly, and after hesitating for a moment, she replied, "With all your little thoughts, do you really think you can hide anything from me?"
At once, Shiyu understood—it was probably their mother who had reminded her. Otherwise, how could Mikoto, whose personality wasn't particularly attentive, have noticed? He'd gotten excited for nothing.
Still, he knew better than to say that aloud. After all, he was no match yet for Mikoto's strength—if he embarrassed her, he'd end up suffering the consequences. Most importantly, now that he had accepted her gift, he needed to figure out how to smoothly change the topic.
Just then, Uchiha Shizhi entered the room carrying a tray of food, and Mikoto hurried over to help him, breaking the tension. Then Shizhi said, "Mikoto, Shiyu, time for dinner. If either of you wants to learn swordsmanship from now on, I'll personally guide both of you."
Uchiha Shizhi believed Shiyu Uchiha's physique was now sufficient for basic sword training, and since he would be supervising directly, there shouldn't be any issues—he decided he'd begin teaching Shiyu sword techniques.
As for Mikoto, she wasn't particularly interested in swordplay but focused more on genjutsu, so he hadn't previously taught her any sword techniques. After all, interest was the best teacher.
Shiyu Uchiha said happily after hearing this: "Thank you, Mother. I'll definitely work very hard and live up to your expectations."
"My standards are very high, so you must take this seriously," Uchiha Shizhi replied gently. "Now, let's eat. You need to keep your strength up for the katana practice." After that, the three of them began eating dinner together.
After dinner, Uchiha Shizhi was cleaning up the tableware when Mikoto Uchiha took Shiyu Uchiha to the backyard for some post-meal training—practicing basic ninja taijutsu.
Mikoto Uchiha kept attacking relentlessly, and Shiyu Uchiha barely managed to dodge, slipping through each strike with just enough defense to stay on his feet. They trained like that for quite a while after dinner. Although Shiyu Uchiha was clearly at a disadvantage throughout, he never got knocked down.
This was obviously because Mikoto Uchiha had been holding back her strength. Ever since that fateful incident, while she always spoke harshly, not once had she actually struck him.
