The Wonders of Sealing Arts!

Kushina was deeply uneasy. Of course, she did not believe that nonsense about Six-Tails Chakra erosion. What Tailed Beast Chakra could possibly be this gentle? This was clearly high-quality Chakra that had been purified and stripped of its negative emotions.

However, she did not expose Menma's lie, because she trusted him. Since Menma had chosen to hide it, she believed he must have had his reasons.

She merely answered Menma's question. "Menma, there's no need to worry for now."

"I just sensed it. Although the amount of Chakra 'eroding' into you is enormous, it's very gentle and basically won't affect you."

"Also, unless someone has special sensory abilities, ordinary sensory Ninja won't be able to detect the Tailed Beast Chakra inside you."

"To be safe, I'll reinforce your Four Symbols Seal again!"

As she spoke, Kushina lifted Menma's clothes, exposing the seal on his stomach.

She carefully sensed it, then said with an odd expression, "Something like this can actually happen?"

"What is it?" Menma asked worriedly.

"It's nothing, just a coincidence." Kushina shook her head, signaling for Menma not to panic. "The Four Symbols Seal I set up before happened to seal the Tailed Beast Chakra as well, so there's no need to go through the trouble of sealing it again.

"Moreover, the Tailed Beast Chakra leaks out through the opening I deliberately left behind and fills your entire body. Your body will instinctively generate Chakra to resist it, which is equivalent to training at all times.

"So over time, the amount of your own Chakra will keep increasing until it matches the Tailed Beast Chakra."

Menma froze for a moment. Wasn't this the same principle as the Ice Bed of the Ancient Tomb Sect in The Return of the Condor Heroes?

But he immediately thought of a problem and asked, "That's not right. As far as I remember, there's a limit to how much Chakra a Ninja can refine. Exceeding that limit damages the body."

Kushina smiled as she explained, "That's true for other people, but it's different for us!

"The Uzumaki Clan is known for its abundant vitality to begin with, not to mention that Tailed Beast Chakra also has healing abilities!"

Menma suddenly understood. So that was how it was!

But then he thought of something else. "Even if we produce a lot of Chakra, the capacity of our chakra reservoirs is limited. Wouldn't the excess Chakra just go to waste?"

Kushina grew increasingly pleased with Menma's quick mind. Smiling, she said, "That's right. A Ninja's chakra reservoir has limited capacity. Although the Uzumaki Clan's reservoirs can hold a little more, they're nowhere near large enough to contain Tailed Beast-level Chakra.

"But fortunately, the Yin Seal passed down secretly within our Uzumaki Clan can solve that problem!

"The Yin Seal can store excess Chakra from the body, which is perfect for dealing with this issue!"

"It can only store it? You can't release it at a critical moment?" Menma spotted the flaw.

"Of course you can. Otherwise, what would be the point of storing it? The Yin Seal has a corresponding release method. Once it's undone, it can release Chakra continuously." Kushina explained solemnly.

Menma understood. "Isn't that Lady Tsunade's Strength of a Hundred Technique?"

Kushina shook her head. "They're completely different. Our Uzumaki Clan's release method opens a small gap and lets the Chakra flow out continuously.

"Lady Tsunade's Strength of a Hundred Technique completely breaks the Yin Seal, releasing a massive amount of Chakra all at once!

"If the Yin Seal were a bathtub full of water, the Uzumaki release method would be like pulling out the plug and letting the water drain slowly and continuously.

"But the Strength of a Hundred Technique would be like smashing the bathtub from the outside, letting all the water pour out in an instant!

"Although the Uzumaki release method doesn't unleash much Chakra in a short burst, it's safer! If you release a huge amount of Chakra all at once, your chakra pathways will burst before you can even use it.

"Lady Tsunade's Strength of a Hundred Technique can unleash a huge amount of Chakra in a short time, but it has to be used together with the S-rank medical Ninjutsu, Creation Rebirth! It's very difficult to learn!"

After hearing that, Menma asked, "Then why haven't you learned the Yin Seal, Mom?"

Kushina smiled proudly. "Because Mom doesn't need it. I'm the Nine-Tails' jinchuriki. Have you ever seen a jinchuriki run out of Chakra?"

Menma laughed as well. "Then doesn't that mean I count as a jinchuriki too?"

Kushina rolled her eyes at him. "How could it be that easy? The Six-Tails Chakra inside you may be abundant, but it's water without a source. Once you use it up, it's gone."

Menma thought for a moment and asked, "Then can the Yin Seal store Six-Tails Chakra?"

Kushina said, "Under normal circumstances, definitely not. Tailed Beast Chakra is extremely violent and unstable, and it would break through the Yin Seal.

"But for some reason, your Six-Tails Chakra is incredibly gentle, so it should be possible to store it with the Yin Seal!"

Hearing this, Menma suddenly had a bold idea. "Mom, what do you think of this? I'll use the Yin Seal to store most of the Six-Tails Chakra, leaving just a small portion inside the Four Symbols Seal.

"Then I'll use the Chakra leaking from the Four Symbols Seal to stimulate my own Chakra refinement, and store the refined Chakra in the Yin Seal too.

"That way, I won't have to worry about my chakra pathways bursting from the massive amount of Chakra after the Four Symbols Seal is released, and I'll have an almost endless supply of Chakra!"

Kushina was also stunned by Menma's idea. She thought it over carefully and realized that it actually seemed feasible!

"Not bad, Menma!" Kushina vigorously ruffled Menma's hair and could not help praising him. "Whether it works or not, Menma, you have to learn the Yin Seal first!"

"Mm-hm, got it!" Menma promised.

At that point, Kushina seemed to suddenly remember something. She sprang to her feet and dashed back into the room.

She returned carrying a huge stack of books and said to Menma, "Menma, these are introductory books on Uzumaki Sealing Arts. I worked hard to gather them while you were out on missions.

"When you learned the Object Sealing Method in such a short time before, I realized that you really have talent in sealing arts!

"I originally planned to give these books to you as a gift after you became a Chunin, but since the timing is perfect now, I'll give them to you early!"

Looking at the stack of books half as tall as he was, Menma was so "moved" that tears nearly streamed down his face. He had not expected that even after transmigrating into the world of Naruto, he still could not escape the fate of grinding through textbooks.

"Mom... thank you. These books must have cost a lot, right?" Menma asked. "If they were too expensive, why not return a few of them?"

Kushina seemed not to hear the hidden meaning in his words at all. She waved her hand with a smile. "As long as you're willing to study, Mom is willing to spend however much it takes!"
