I'm in Bleach, starting with Unlimited Blade Works.

King of Spirits!

The divine artifact "Eight Mirrors Sword" was used by the five noble ancestors to prevent the "Spirit King" from one day wanting to break free of the sealing crystal and take revenge on them. The "Eight Mirrors Sword" was the trump card of the five nobles to deal with the Spirit King.

However, although the "Spirit King" would not do that, instinctively, the Spirit King's will would reject anything harmful to him. That is why the artifact "Eight Mirrors Sword" was cursed.

Anyone who uses the divine artifact "Eight Mirrors Sword" will die a violent death.

Each occurrence of this curse proves that the Ise family has harmed the "god" of death.

From this perspective, the Ise family is very likely on the same side as the Tsuna-Yashiro family.

Perhaps only the divine weapon "Eight Mirrors Sword" could sever the Spirit King's limbs and rip out his internal organs...

Ise Nanao's mother may have been at the behest of the previous head of the Tsunayo family when she attacked the "Soul King," thus witnessing the greatest darkness in Soul Society.

That's why she secretly gave the sacred treasury passed down through generations of the Ise family to Kyoraku Shunsui. After her husband was killed, she didn't think about revenge, but instead committed suicide to atone for her sins...

As for who killed Ise Nanao's father, Erin thought there was no other candidate besides Tsunayoshi Tokinada.

The one who made Ise Nanao's mother use the "Eight Mirrors Sword" was the previous head of the Tsunayo family.

After killing everyone in the Tsunayo family, Tsunayo obtained the secret of the "Spirit King". Then, by collecting the "Spirit King fragments" from the bodies of the Manifestation users with Michiha Ne Aura, and combining them with Hollows, the Shinigami created the incomplete "Murakuchi Hikoya".

However, due to the lack of "annihilation power", the current Chanjuan Yanmi has no part above the neck at all, and only relies on the spiritual power flow between her own lock and soul saliva to maintain the characteristics of life.

In order to make Hikoya Sanjuan whole again, Tsunayoshi attempted to have Nanao Ise's mother attack the Soul King again, but Nanao Ise's mother refused.

Even if Ise Nanao's mother had already entrusted the sacred weapon to Kyoraku Shunsui for safekeeping, she would still have been unwilling to wield the sword against that "god" again.

More than a million years ago, the five noble families were able to control these "powers".

Now, those upper-class nobles who want to be promoted to "great nobles" naturally need to seize the corresponding power from the five great nobles.

The other three great noble families were still at the height of their power.

Even though he was the only one left, Tsunayoshi Tokinada, who was in charge of the "Erota Mirror Codex", was still one of the five great noble families of Seireitei, with many upper-class nobles and lower-class nobles serving him.

That is, the Shiba family. Because they have always wanted to publicize the crimes of the five noble families, they have been resisted by all the noble families. No noble family would be so foolish as to serve the Shiba family.

If they can obtain the Shiba family's inheritance and acquire the tool that can send people to the Spirit King Palace, they will gain the power of a "Great Noble" and successfully replace the declining Shiba family to become the new "Fifth Great Noble".

……

"Hado #31 - Red Fire Cannon!"

In the underground base left behind by Kisuke Urahara, Nanao Ise used Shunpo to leave the location of the child.

The next moment, a red fireball struck the spot where Ise Nanao had been standing, causing a massive explosion.

"Hado No. 12 - Hidden Fire!"

Ise Nanao's figure appeared in the air, chanting a Kido incantation. With a wave of her hand, seven or eight fist-sized fireballs immediately attacked Erin.

"The Eighth Binding Path - Rebuke!"

Faced with the incoming fireballs, Erin waved his hand, and instantly, an invisible repulsive force centered on Erin deflected the fireballs.

"Boom boom boom boom..."

These fireballs struck the ground around Erin, and the energy within them exploded, blasting craters nearly a meter in size into the ground.

"One of the broken ways - charge!"

After deflecting the fireball, Erin bent his other fingers, leaving only his right index finger pointing at Ise Nanao. A transparent shockwave shot towards Ise Nanao in mid-air.

"The Eighth Binding Path - Rebuke!"

Ise Nanao stretched her hands forward, creating a repulsive wall in front of her.

"Oh!"

With a soft thud, Ise Nanao was repelled.

"Binding Spell Number Four - Gray Rope!"

Just as Ise Nanao was about to continue attacking Erin, a golden rope of light appeared beside her and tightly bound her hands.

"You've lost, Nanao."

The other end of the light cord was in Erin's hand.

With a pull, Erin dragged Ise Nanao down from the air. Just as she was about to fall to the ground, Erin released the rope. Ise Nanao, now free, touched the ground with her hand, somersaulted, and stood half-bent in front of Erin.

"Not bad, Nanao, you are now quite proficient in using the Kido."

Although Ise Nanao didn't last long against Erin, Erin could still tell that Ise Nanao had developed her own "method" for using Kido.

"I'm not even close yet."

Ise Nanao did not show any pride in Uncle Erin's praise.

Although she could feel her strength growing rapidly during this period, no matter how strong she was, it seemed to make no difference in front of Uncle Erin.

From the time she started learning from Uncle Erin until now, nearly three months have passed, and every battle between her and Uncle Erin has ended in fifteen minutes.

"Haha, Qixu, don't be discouraged. There aren't many people your age who have your strength."

Seeing that Ise Nanao's mood wasn't very high, Erin wondered if he had been too obvious.

In every battle with Ise Nanao, Erin would time it to a quarter of an hour.

Combat using Kido is inherently a battle of "wisdom".

In what kind of setting and which type of ghost path will achieve better results?

In this short period of time, Erin might try to surpass Ise Nanao in speed, or strength, or perhaps use more disruptive binding techniques...

Aside from spending the first two months learning new Kido techniques, Erin spent the following month simulating various abilities under different environments to fight against Ise Nanao.

After this period of training, aside from the Kido, Nanao's Shunpo has made great progress.

"Nanatsu, you must understand that all battles are fought while ensuring your own safety and defeating or killing the enemy."

"Therefore, before a battle, you must always remain calm, observe the surrounding battlefield, consider your own advantages over the enemy, find ways to turn your advantages into a winning position, and find ways to turn your disadvantages into advantages."

"Yes, I understand, Uncle Erin."

"There are still a few days left until the three-month period ends. In these few days, I'll teach you another very interesting trick."

"If you can learn this technique, you'll have a place among the vice-captains of the entire Gotei 13!"

"This technique is a purely sensory technique, which I call 'Perception'."

"First, let's look at the Fifty-Seven Binding Techniques: Slapping the Toe and Chasing the Sparrow, and then we'll observe the Seventy-Seven Binding Techniques: Heavenly Sky-Piercing Net..."

"Both of these Kido are tracking Kido that can sense and lock onto other people's spiritual pressure."

Erin had also taught the technique of "observation" to his second disciple, Gin Ichimaru.

Combining Kido (鬼道) with Hakuda (白打) is called "Shunko" (瞬哄).

This is a technique developed by Yoruichi Shihouin that is comparable to the Bankai ability of a Zanpakuto.

After obtaining Yoruichi Shihouin and Soi Fon's Zanpakuto, Erin gained more insights into the fusion of Kido spiritual pressure and his own spiritual pressure from the two of them.

Yoruichi Shihouin, Soi Fon, and Yushiro Shihouin's "Shunko" is an offensive technique that combines the spiritual pressure of Kido, or more accurately, "Hado".

"Observation Haki" is Erin's version of "Observation Haki," which combines the theory of "Instantaneous Haki" with the training system of another world in his mind. He ultimately created the Shinigami version of "Observation Haki" by merging the spiritual pressure of the Binding Path with his own spiritual pressure.

Unlike "Instant Roar," which greatly amplifies one's own offensive capabilities, "Observation" is more of a supportive ability.

After activating "Perception", one's perception of the surrounding area will be amplified, allowing one to sense the enemy's attack trajectory and movement pattern. At a higher level of cultivation, one may even be able to encounter the enemy's attacks.

In Erin's view, "Instant Haki" is similar to "Armament Haki" in the world of One Piece. Whether "Armament" or "Observation" is stronger is not definitive.

It all comes down to which one suits you better.

Take Ise Nanao for example. Even if Erin taught her "Instant Hurricane," with her terrible hand-to-hand combat skills, she would probably be defeated by the enemy before she could even attack.

However, "Kakuya" is different. With the help of "Kakuya", Ise Nanao has a great ability to adapt to the battlefield, which allows her to better use various Kido to deal with enemies.

And Gin Ichimaru goes without saying.

The ability to "see and hear" is a perfect match for the abilities of his Zanpakuto, "Shinso".

Within the range of "Kanken's" perception, no one can escape Gin Ichimaru's attacks.

Of course, powerful abilities are usually not something that can be fully learned in a short period of time.

Even if you learn it, you'll still need more time to familiarize yourself with it before you can apply it in combat.

Next, in order to let Ise Nanao understand the ability of "seeing and hearing", Erin closed his eyes and stood in front of Ise Nanao.

"Nanatsu, you can use any means to attack me now, I will not retaliate or defend myself."

"If you can force me out of this circle within fifteen minutes, I will tell you something about your Ise family."

"Really?"

Upon hearing Erin's words, Ise Nanao's expression immediately turned serious.

Ise Nanao has been a member of the 8th Division for several decades.

However, in the decades of investigation, the Ise Nanao incident occurred, and there are almost no records of the Ise family in Soul Society.

It was as if the Ise family didn't exist at all in the entire Seireitei.

This situation is highly unusual, unless someone is deliberately trying to erase the existence of the Ise family.

Chapter 169 The Power of Observations

Uncle Erin has been the captain for so many years, and the information he knows is far more accurate and useful than anything I could find myself.

As for whether Uncle Erin would lie to her, Ise Nanao didn't even question it.

"of course."

With a wave of his hand, a circle about two meters in diameter appeared beneath his feet.

"Nanao, let's begin."

When the spiritual pressure of the Kido attribute merges with one's own spiritual pressure, it will temporarily increase one's own spiritual pressure.

Of course, the boost from the fusion of Binding Dao attribute spiritual pressure is far less than the boost from the fusion of Hado attribute spiritual pressure.

However, the spiritual pressure of the Binding Path attribute is much gentler than that of the Hado attribute. The outward manifestation of "Kenwa" is not as explosive as "Shunho," but rather appears calm and serene.
