Eight Trigrams Seal

"Breakfast was this lavish, and completely different from yesterday's spread!"

After getting up and washing up, Uzumaki Mito was once again stunned by the sumptuous feast on the table. She simply could not believe that such an extravagant spread was merely breakfast.

And it was different from what they had eaten last night. Was life in the Shimura Clan really this luxurious?

Good food always whetted one's appetite, and Uzumaki Mito was not someone who liked wasting food. She efficiently finished the entire table of breakfast before flopping onto the sofa with her slightly bulging stomach and playing dead.

"Miss Mido, do you have any Fuinjutsu that can store unused chakra away and let me draw it out when I need it? Preferably something I can learn and use right away.

"I can trade you our Shimura Clan's complete Body Strengthening Secret Technique—trade it to the Uzumaki Clan."

Carrying two cups of tea into the living room, Shimura Kentei sat down and placed one before Uzumaki Mito before making his request.

Thanks to last night's meal, he had grown much closer to this young lady. It was time to begin the transaction.

His greatest weakness now was his chakra reserves. Even though the Super Strength Technique and Super Speed Technique consumed little chakra, if he used both at once, he could only be a real man for one minute at most.

Once he ran out of chakra, his combat power would plummet. He had to find a way to address this weakness.

Meeting Uzumaki Mito this time had made him think of Fuinjutsu.

"You want to make a trade with our Uzumaki Clan?"

Sitting upright, Uzumaki Mito asked seriously.

The Uzumaki Clan was different from the ninja clans of Konoha. Though they were Konoha's allies, they were still outsiders. Would the Shimura Clan truly agree to pass that Body Strengthening Technique on to the Uzumaki Clan?

"You don't need to worry about my father or the clan. I can make this decision."

As he spoke, Shimura Kentei took out a Sealed Item Scroll containing the complete Body Strengthening Secret Technique.

Uzumaki Mito's heart stirred as she looked at the Sealed Item Scroll pushed onto the table before her.

She had examined that Body Strengthening Secret Technique before. While it took an unorthodox path and was filled with countless dangers, there would be few problems as long as one cultivated it step by step.

Most importantly, it had almost no entry requirements. To an entire clan, its value was immeasurable.

After thinking briefly, Uzumaki Mito accepted the Sealed Item Scroll. "I know quite a few seals that can store chakra you do not normally use. The strongest is the Yin Seal, the one on my forehead. However, cultivating the Yin Seal requires chakra with both Yin and Yang Release. You are not suited for it."

She pointed to the diamond-shaped mark between her brows, dismissing Shimura Kentei's talent in that regard.

"But doesn't Teacher Tsunade only have Yang Release and no Yin Attribute?"

Shimura Kentei was puzzled. He knew perfectly well that he lacked the necessary aptitude. Because he had been born prematurely, his chakra had not developed innate attributes in his mother's womb before he was born.

Forget Yin and Yang Release—even the five common attributes of Wind, Fire, Lightning, Water, and Earth were absent.

Yet he remembered that Tsunade did not possess both Yin and Yang either. She did not have a Yin Attribute.

"The Yin Seal only requires chakra with Yin and Yang Release. It does not necessarily require you to possess both Yin and Yang Attributes. Yin and Yang Release cultivated later in life will work as well.

"In your Shimura Family's terms, acquired Yin-Yang Release chakra can barely suffice to cultivate the Yin Seal. Tsunade only developed acquired Yin Attribute chakra some time ago, which finally met the requirements for cultivating the Yin Seal."

Uzumaki Mito patiently explained in detail while secretly considering which Fuinjutsu to pass on to this little brother.

That Body Strengthening Secret Technique might not be high-level, but its value was immeasurable. Especially for a large clan, it could double the Uzumaki Clan's strength.

Since he had shown such sincerity, she naturally could not be stingy.

"Right, the Eight Trigrams Seal!"

After considering the Fuinjutsu she knew, Uzumaki Mito quickly made her choice.

"The Eight Trigrams Seal?"

Shimura Kentei's heart stirred. From the Naruto anime he had watched in his previous life, he knew a little about this seal. The Eight Trigrams Seal was what had been used on Uzumaki Naruto, firmly sealing the Nine-Tails inside him.

"Seals that store your own chakra generally need to be constructed by the user, like the Yin Seal. Others cannot assist with them.

"But the Eight Trigrams Seal is different. I can complete it directly on your body.

"This seal was originally meant to deal with a huge creature. It could extract that creature's power and convert it into the seal bearer's own chakra. Unfortunately, the Eight Trigrams Seal can only extract single-attribute chakra, while that huge creature happened to possess both Yin and Yang attributes.

"And that creature was far too powerful, so the Eight Trigrams Seal became a failed creation."

At the end, Uzumaki Mito could not help sighing.

The Eight Trigrams Seal had been created by her. It was formed from two Four Symbols Seals, intended to refine the Nine-Tails' chakra into her own power. Unfortunately, the Nine-Tails had been too powerful, and she had failed.

"Kurama?"

Shimura Kentei understood. The huge creature Miss Mido had mentioned had to be Kurama, the Nine-Tails. He also understood why Minato Namikaze had used the Eight Trigrams Seal to seal the Nine-Tails inside his son.

As Miss Mido had said, the Eight Trigrams Seal was indeed a failed creation when used on the complete Nine-Tails. But if the Nine-Tails were split into Yin and Yang halves, things would be different, and its effectiveness could be maximized.

"No wonder Uzumaki Naruto's chakra reserves were so enormous in the original story. The answer was the Eight Trigrams Seal."

Shimura Kentei finally understood. Back when he watched Naruto, he had found it strange that freshly graduated Uzumaki Naruto possessed a hundred times Kakashi's chakra. It was utterly insane.

Kakashi might have been severely lacking in stamina, but he possessed Yang Release. Any ninja with Yang Release chakra would have respectable chakra reserves.

Even so, it was clearly abnormal for twelve-year-old Uzumaki Naruto to have that much chakra. Even if he was Asura's reincarnation, it was excessive. Now Shimura Kentei finally understood: Naruto had relied on the Eight Trigrams Seal to refine the Yang Nine-Tails' chakra.

"Take off that suit. I'll carve the Eight Trigrams Seal for you!"

As Uzumaki Mito removed her own loose, cumbersome outer robe, she gestured for Shimura Kentei to remove his suit as well. She intended to carve the Eight Trigrams Seal for him immediately.

Naturally, Shimura Kentei would not refuse such a good thing. He swiftly removed his outer and inner armor, leaving only the Venom Suit covering his body.

"You've got a pretty good body, little brother. You really don't look like you're only thirteen!"

Uzumaki Mito examined Shimura Kentei's sharply defined physique beneath the Venom Suit and could not help teasing him.

"Our Shimura Clan's Body Strengthening Secret Technique can speed up physical development to a certain extent!"

He smiled modestly, though he could not hide his pride.

This body was forged through years of hard training. It was absolutely the favorite of lovestruck young girls and lonely married women!

"Enough nonsense. Expose your upper body!"

Rolling her eyes at him, Uzumaki Mito gestured for Shimura Kentei to reveal his upper body, then asked, "Are the chakra pathways in your body left-handed or right-handed spirals?"

"Left-handed. Why?"

Shimura Kentei answered truthfully. He understood this clearly: the meridians in the chest and abdomen formed a spiral structure. Based on their direction of rotation, they were divided into left-handed and right-handed spirals.

The chakra extraction technique circulated chakra in a spiral through the meridians, absorbing spiritual and physical energy to fuse into new chakra.

"The Eight Trigrams Seal will simulate a meridian vortex. It must rotate in the opposite direction to your own meridian vortex so that they can connect perfectly."

After briefly explaining, Uzumaki Mito condensed chakra with Yin and Yang Release at her fingertips and began inscribing chakra formulas around Shimura Kentei's navel. This was the preparatory work.

"This might hurt a little. Bear with it!"

After finishing the complicated, profound chakra formulas, Uzumaki Mito rotated her wrist. She looked eager to begin, and the sight suddenly made Shimura Kentei uneasy.

"Might? Miss Mido, haven't you used this before?"

Shimura Kentei's eyes widened. He felt as though he had become a lab rat.

"Don't worry. It won't kill you!"

Uzumaki Mito replied with a smile. It truly was her first time using the Eight Trigrams Seal, and she was not completely confident, though she had at least a seventy percent chance of success.

"That makes me even less reassured!"

Shimura Kentei complained helplessly, then closed his eyes as though resigning himself to his fate.

Since even baby Uzumaki Naruto had succeeded in the original story, there was no reason he could not.

"Hiss!"

He suddenly felt a small hand press against his navel, followed by indescribable agony, as though dozens of steel blades had stabbed into his abdomen and were cruelly twisting inside.

The intense pain made his eyes fly open as he sucked in a breath, doing his part to warm the entire Naruto world.

"Miss Mido, be gentler. It hurts a little!"

His voice trembled as Shimura Kentei felt that he was about to reach his limit.

Only because Keiko's replicas had tortured and killed him in all sorts of ways within the Black Cauldron Space over the past few years did he possess extraordinary pain tolerance. Anyone else would have passed out from the agony long ago.

Uzumaki Mito said nothing, her beautiful face filled with solemn concentration.

Although she had created the Eight Trigrams Seal and understood it inside and out, this was still her first time using it, so unexpected situations were bound to arise.

Moreover, this time she was creating a blank Eight Trigrams Seal with no sealed object inside it. It differed greatly from the conditions she had previously calculated.

She could only slowly adjust for these differences, and the process would indeed produce severe pain.

Thinking of this, she glanced at Shimura Kentei in surprise as he endured without moving. She was deeply impressed by his willpower and endurance.

Though she was not experiencing the pain herself, she knew exactly how severe it was. It was more than ten times more painful than childbirth, and the agony covered his entire chest and abdomen, a far greater area than the pain of childbirth.

Yet even so, the boy had not cried out once. He could even remain still. Such endurance and willpower were truly rare.

"That bastard!"

At the same time, Senju Nawaki was crouched outside the window, watching the scene inside. Hearing Shimura Kentei's trembling voice, he gritted his teeth in fury.

From where he stood, his back was facing Uzumaki Mito. From that angle, the pair's posture looked incredibly suggestive.

Other children might not understand, but he was different. He had studied under Big Brother Jiraiya and had seen similar poses in the illustrations of The Paradise of Passion. Together with Shimura Kentei's trembling voice, which sounded as though he were enjoying himself to the extreme, Nawaki became even more certain.

Yesterday, he had only noticed that the two were acting intimately and ambiguously. Who would have thought they had progressed this far already? His sister had let a wolf into the house!

At that moment, Senju Nawaki felt that grass might be growing on his grandfather's grave—lush, green grass at that.

"No, I need to report this to my sister right away!"

After casting a resentful glance at the bastard lying on the sofa in the living room and trembling faintly in pleasure, Senju Nawaki rushed toward the secret chamber, intending to inform his sister and uncle of this intelligence.

He had neither the means nor the ability to deal with this himself. He could only let his sister and uncle think of something.

In any case, he absolutely could not let this continue. Otherwise, he might not only gain a step-grandfather, but one or several new uncles and aunts as well.
