Chapter 57: Yin Seal and Eight Trigrams Seal!

Chapter 57: Chapter 57: Yin Seal and Eight Trigrams Seal!

The Yin Seal technique originated from Tsunade's grandmother, Uzumaki Mito.

It could be said that this technique belongs to the Uzumaki Clan, but in reality, no member of the Uzumaki Clan had ever practiced it before Uzumaki Mito.

This was because Uzumaki Mito herself was the creator of the technique.

The reason she chose to place it on the forehead was naturally due to the fact that the tailed beast within her was sealed in her abdomen.

In fact, the Yin Seal was originally developed as a countermeasure against the Nine-Tails, using a vast amount of chakra to suppress it.

The Nine-Tails had been sealed within Uzumaki Mito for so long without causing any issues and was thoroughly subdued—not only because of Mito's own strength but also due to the effectiveness of the Yin Seal.

Of course, Tsunade didn't mention any of this to Shūichi Hoshita.

Instead, she said, "There's no problem with placing the Yin Seal on the abdomen, but how do you plan to address the issue we discussed last time?"

She had a solution in mind, but she wanted to test Shūichi's understanding.

Shūichi smiled and replied, "Lady Tsunade, you're surely familiar with the Four Symbols Seal."

"I once asked Minato-sensei about sealing techniques, and he taught me this particular seal."

"So, my idea is to use two Four Symbols Seals in conjunction with the Yin Seal to create a cycle—one seal for intake and the other for output, ensuring they don't interfere with each other."

Tsunade fell into deep thought, her mind already beginning to piece together the combination of the three seals.

After a moment, she nodded, "Technically, this seems feasible."

"And this design does indeed suit you better."

"However, it does add a significant level of difficulty. Besides mastering the Yin Seal, you'll also need to learn the Four Symbols Seal, which will require more time."

Shūichi chuckled, "Although I do feel like my chakra is insufficient at times, I'm not even seven years old yet—there's no rush!"

Tsunade, seeing his confidence, didn't argue further and nodded, "Alright, let's proceed with this plan."

"You can ask Minato to teach you the Four Symbols Seal."

With that, she cracked her knuckles, the joints popping loudly, "Since you're not learning the Yin Seal today, let's resume our sparring from before!"

"Your control over chakra bursts is still quite unrefined."

Shūichi's eyelids twitched, and he quickly responded, "Wait, Lady Tsunade."

"Although placing the Yin Seal on the abdomen is a good idea, it doesn't mean I should abandon the previous approach."

Why choose when you can have it all?

...

At the residence of the Nine-Tails Jinchūriki.

Jiraiya found Minato Namikaze there, studying sealing techniques with Kushina Uzumaki.

...

After returning home from the Konoha Hospital, Shūichi Hoshita officially began training in the Yin Seal.

Simply put, the Yin Seal involves creating a chakra storage area at the point between the eyebrows, which can be thought of as a reservoir, with chakra being the water.

However, unlike Tsunade, Shūichi needed to create two reservoirs—one large and one small.

The larger one was specifically for storing chakra to be used in critical moments.

The smaller one was for everyday use.

Although this approach was somewhat cumbersome, until he mastered the Four Symbols Seal and Eight Trigrams Seal, this was the best he could do.

Unlike when he used the Memory Palace Seal, Shūichi's skills in sealing techniques had significantly improved.

He no longer needed to pre-draw the sealing script before using it. Instead, he could use hand seals to assist in transforming his chakra into talismans, forming the sealing script.

Still, it took him a full minute to complete the hand seals.

"Yin Seal!"

As he completed the final hand seal, Shūichi brought his hands together, and his body was immediately covered in dense, tadpole-like symbols.

These symbols then converged toward his forehead, forming the Yin Seal mark before it faded from sight.

Afterward, Shūichi lowered his eyes and began refining his chakra, channeling it into the two reservoirs within the seal.

On October 6, Year 39 of the Konoha Calendar, Shūichi Hoshita officially began training in the Yin Seal!

To better develop new jutsu and achieve the [Medical Expert] tag, Shūichi started reducing his missions outside the village. Most of his time was spent at the Konoha Hospital or training within the village, occasionally going on missions with Minato and the others.

Before he knew it, the temperature began to drop, signaling that autumn was deepening.

One day, feeling exhausted, Shūichi invited Tsunade to relax at a hot spring, but when she declined, he decided to head to Konoha's hot spring street alone for some well-deserved relaxation.

"Huh?"

Shūichi noticed someone on the roof.

"That old pervert Jiraiya..."

Shūichi stopped in his tracks.

Peeping? How immoral! This definitely needs a stern reprimand.
