Fascinating.

That's what a first word came to her mind as she was reading a fairly thick book. The six years old heiress spent a couple of hours there since her mother first bought her and later left her alone under the supervision of the woman named Yomiko Shihoin whose her responsibility to oversee the legendary library. The Library of the Benzation rapidly became her number one favorite place. There's so many interesting books there!

Within these books, the trove of the priceless treasures waited to be discovered by the eager, inquisitive hands of the Shihoin heiress. Like this thick book that she found and was currently reading, it titled 'The Unique Properties of the Yang Chakra.' It was written by Shihoin Myūzu, who lived centuries ago before her time.

Some of the tidbits were completely new to her. For an example, she was reading a current chapter talking about the Yang Chakra was powering the vitality of the living being. Their bodies' self healing process depended on the density of the yang chakra. It was also related to how much stamina they have and how long they live. More denser the yang chakra is, more higher stamina and long lifespan they likely have. The Uzumaki Clan was a classic example of the result of having the most densest yang chakra out all of the ninja clans in the Ninja World.

To her surprise, according to this chapter that she was reading, explained that her own clan would be considered falling into the similar category as the Uzumaki Clan, although her clan's yang chakra density was inferior than the Uzumaki clan, but superior than the most of the ninja clans. According to her book, the males usually had the yang chakra in a high amount naturally compared to the females who had a low amount of the yang chakra.

In simple words, the females were weaker than their male counterparts in the term of the physical strength and stamina. A same theory applied to the Yin Chakra, the females had the yin chakra more than the males; Hence the females had a better chakra control and better adapted to the spiritual aspect of the chakra compared the males and vice versa.

Her clan was a unique case. The stamina and physical prowess of the females in her clan was higher than normal, much higher compared the ordinary kunoichis. It meant that they could able to hold their direct taijustu match against their male counterparts longer than the average kunoichis. Only the members of the Uzumaki Clan and the stronger than average males outclassed them in the term of the stamina and the physical strength.

Interestingly, an authoress mentioned that her clan would be easily par on with the Uzumaki Clan in the same capacity, had it not been for the slight difference on how their bodies used the yang chakra in their own way. The Uzumaki body used the yang chakra to power its vitality to the greatest extent possible. That's a main reason why the Uzumaki Clan had the ridiculously long lifespan and could live up to 150 years, or on the rare occasions they could reach to 200 years if they did not participate actively in the dangerous lifestyle of being a ninja.

Now, in her clan's case, unlike the Uzumaki Clan, their bodies spent the half of their yang chakra devoted to their stamina. That's why the Shihoin kunoichis were much stronger than the average kunoichis from the ninja clans and capable to fight on par with their male counterparts. The Shihoin Clan's typical life expectancy was usually 120 years, or less. Much lesser than the average Uzumaki lifespan, but more longer than the ordinary human lifespan.

So, where was the other half of their yang chakra going to? To her astonishment, her book revealed that their bodies devoted the other half of the yang chakra to their reproductive system. In other words, the fertility in the women of the Shihoin clan was extremely potent and caused their childbearing years, extending 20 years more than the average human childbearing years. Its potent effect also applied to the virility of the male Shihoin as well. However, the authoress added the note that both female and male Shihoins tended to produce the female offspring more often rather than male offspring.

Myūzu theorized that having that unusual amount of the yang chakra in their reproduction system caused this condition. According to this book, it was likely stemmed from their bloodli-.

She jerked up her blue-green eyes away from her book that attracted her attention so much that she did not notice a foreign chakra signature came close to her until her sensory bloodline poked her awareness insistently and hard enough to make her finally notice another chakra signature approached too close within her comfort zone.

The little girl saw a familiar form of the legendary library's overseer standing over her. She gently closed her book with the reverence. She went back to look at an older woman.

"Masumi-sama, I see that you enjoy this book." The library overseer said with the amused expression. She was a a slender woman with the slight curves, her hair had a lovely, soft shade of the pastel green and her pale blue eyes twinkled with the kindness and amusement.

"Ah, Yomiko-chan! Yes, This book is very interesting. I learn a lot from this one." Masumi told her in the exciting tone. Yomiko smiled at her enthusiasm.

"Indeed, it is. This book is very good. Many people considered it a well-recommended book..." An older woman continued. "Anyway, I believe that your time to stay here is up. It's a time to go now."

"Aw, Yomiko-chan! can I stay here just a little longer? " A blue-green eyed girl pouted cutely in hope to convince an older woman let her stay in this marvelous place little longer.

"I'm sorry, it's a rule. Everyone must obey that rule for their own good or otherwise it do us no good if we stay here for too long. Asami is going to pick you up soon." Yomiko said firmly with the nonsense tone, not being swaying easily by the clan heiress.

Sensing her firm refusal, Masumi looked a bit disappointing. She then brightened slightly when an idea came to her.

"Can I borrow this book?"

"Of course, you can. But just limit to one book."

"Just one? That's it?"

"Yes. And you should return this book to this in due a month. Please treat this book carefully. If you dare to damage this book in any forms, well then... I'm certainly sure that your mother will allow me punish you despite your rank as the Clan Heiress." Yomiko said ominously when she emphasized the latter two sentences.

Masumi gulped at being received the ominous warning from the supposed sweet woman. She could feel the dangerous vibes from Yomiko's chakra.

"Um..if I did, what kind of the punishment you punish me with?" Masumi dared to ask bravely, her eyes wide and her arms closed around a book protectively.

Yomiko just smiled sweetly and answered, "Ban you from entering from this library for three months and you must completely replace the damaged parts depending on the level of the damage to this book. All the repairs by yourself. If this kind of damage is irreversible, then we do have a copy of that original book just in a case. You must make a new second book by duplicating the backup copy. In other words, you will write the exact words down from the backup copy with your own hands. I heard this kind of punishment is very helpful to improve your calligraphy."

Masumi winced at that. It sounded a bit harsh but fair. It would install a good lesson in younger children to respect the books. Nobody wanted to get banned from this wonderful place and went though the old fashioned process to repair the damaged book.

"I solemnly promise that I will return this book in a perfect condition." She told the older woman with a totally serious expression on her face.

Yomiko smiled widely, "Good! I'm sure that you will." Then she paused in a second as her sensory range detected something.

"Ah, Asami-chan is here! Now, it's a time to leave here." Yomiko gestured her to stand up and come with her. Reluctantly, Masumi was standing up from her comfortable chair along a thick book in her arms.

They both walked across the hall and ahead toward the doors. Masumi's mind wandered back to a book that she previously read earlier before Yomiko interrupted her reading.

She was forward to finish reading this interesting book when she had a free time. After all, the Shihoin Clan, where the women allowed to express their curiosity freely, spent the hundreds and hundreds years to write down on their own books about their study and experimenting on the chakra in their spare times.


A/N: Ohh, How interesting! Masumi definitely learns some interesting stuffs about the Shihoin chakra. The women in the Shihoin Clan are definitely intelligent especially Myuzu Shihoin sounds like that she is a sort of the scientist to study the chakra. Pretty cool, eh? ;)

I hope that you like the Yang Chakra theory stuffs. Anyway, please kindly review this chapter. Your reviews feeds my motivation to write more!
