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

A tremendous spiritual pressure erupted from Erin's body.

The powerful spiritual pressure even caused a white light to emanate from around Erin.

These rays of light are the outward manifestation of powerful spiritual energy.

Erin's Zanpakuto transformed into a giant fang-shaped blade radiating white light.

“Watch closely, Yincheng.”

"Wind injury!"

With a gentle wave of his hand, Erin unleashed three massive wind slashes that shot into the sky, their immense power seemingly capable of tearing everything in the heavens apart.

"boom!"

Ginjou Kūgo stared at the sky in disbelief.

After Erin's attack, the entire sky was emptied, and all the clouds in the air were swept away by the frenzied slashes.

"how?"

"Mr. Erin, I want to learn this!"

Upon hearing Erin's question, Ginjou's eyes lit up, and he pointed to the sky and addressed Erin.

"Ha, you haven't even learned to crawl yet, and you want to learn to run?"

"Practice this move again when you've fully unleashed your Zanpakuto!"

"Ah."

In order to learn that cool slash, Ginjo Kūgo stopped bothering Erin to practice actual combat and instead devoted most of his time to the training of "Sword Zen".

Of course, in order to soothe Ginjo Kūgo's restless heart, Erin also taught Ginjo Kūgo the technique "Getsuga Tenshū," which involves condensing spiritual pressure into a slash. As for how much power he can unleash, that depends on his practice and his own spiritual pressure.

A month later, when Ginjo Kūgo successfully completed his training in "Sword Zen" and was able to nurture his Zanpakutō with his own soul, Erin ended his teaching session and returned to Seireitei.

……

In the rotten wood house, Erin sat cross-legged in the courtyard, immersing his mind in the inherent barrier.

A golden key floated in Erin's palm.

This is a weapon that Erin created based on the spatial power of the "Royal Seal".

Its name is—the City of Gold.

Of course, the other name is more well-known than this one.

The King's Treasure.

Previously, because his Infinite Blade Works ability partially overlapped with Gate of Babylon, Erin did not create this Noble Phantasm.

However, with Erin's recent increase in strength, the ability to project weapons using Unlimited Blade Works now seems somewhat useless to Erin.

So, having some free time this time, Erin decided to make this "weapon".

However, after Erin created the key to the "Golden City," he suddenly felt that his Zanpakuto—not the Tessaiga at his waist, nor any of the Zanpakuto Erin had created, but Erin's true Zanpakuto, the one that Erin had kept at the very top of the sword mound after awakening the "Unlimited Blade Works" ability—was trembling slightly.

"Buzzing..."

Sensing the unusual movement of his Zanpakuto, Erin instantly appeared at the top of the sword mound in a blink of an eye.

"This is?"

As Erin approached his Zanpakuto, the Zanpakuto vibrated more intensely. Moreover, the key to the "Golden City" in Erin's hand also began to tremble.

"You want to fuse my Zanpakuto with the Golden City?"

Although surprised that his own Zanpakuto had a tendency to merge with the Zanpakuto he had created, Erin didn't hesitate and directly handed the golden key in his hand to the vicinity of the Zanpakuto.

"Buzzing..."

As the frequency of Erin's Zanpakuto and the Golden City gradually synchronized, the Golden City in Erin's hand turned into golden powder and merged into Erin's Zanpakuto.

Instantly, through the connection with his Zanpakuto, Erin felt that his Reality Marble had been strengthened.

Since Erin awakened the "Unlimited Blade Works" ability, with each Zanpakuto he forged, the space of Unlimited Blade Works became more stable, and Erin felt that it was becoming more powerful.

Several years ago, Erin had sensed that his Reality Marble had reached a limit, and that once he broke through that limit, Unlimited Blade Works would become even stronger.

Over the years, Erin has created many more weapons, and his spiritual pressure has continued to grow stronger.

However, none of these inherent barriers have broken through their limits.

Unexpectedly, the "Golden City" was created today, and this limit was instantly broken.

At this moment, Erin's Zanpakuto had completely turned gold.

Centered on Erin's Zanpakuto, a layer of golden light slowly spread outwards, eventually dyeing everything in the entire space gold.

"boom--"

This time, the breakthrough in Unlimited Blade Works caused Erin's spiritual pressure to surge. Soon, Erin's spiritual pressure had exceeded the level when he released his Zanpakuto, almost reaching the level when he used Bankai, before it slowly subsided.

In other words, Erin's normal spiritual pressure is now at least eight times higher than before.

Under these circumstances, Erin felt that even the "Kutsu" he had encountered a few years ago could be shattered by his spiritual pressure alone.

Although he didn't feel the "limit of a Shinigami" like Aizen did, Erin knew that he had already broken through the limits of a Shinigami and reached a higher realm.

Perhaps only the guards of the Spirit King Palace can rival him at this level.

However, the divine generals in the Spirit King's Palace used the power of the Spirit King to reconstruct their "bones," making their "bones" "Spirit King's Bones," which is why they possessed such powerful spiritual pressure.

However, Erin managed to break through this limit by relying on the breakthrough of his inherent barrier.

After his breakthrough was complete, Erin did not leave the Reality Barrier immediately. Instead, he held his Zanpakuto in his hand and began to comprehend his abilities.

The Golden City—no, the power of "Golden City"—is to automatically collect and store all the treasures in the world that belong to the "King".

Its level will increase as the quantity and quality of the treasures collected increase.

After fusing with Erin's Zanpakuto, Erin's Reality Marble now also possesses the characteristics of "Gate of Babylon," which means it automatically collects all treasures in the world and stores them within Erin's Unlimited Blade Works.

However, due to Erin's own characteristics, Unlimited Blade Works will only collect weapons in the world that have the concept of "sword" and store them in Unlimited Blade Works to enhance its strength.

The moment Erin sensed this ability, the image that flashed through his mind was that of Ichibei Hyosube, currently the strongest person in the Bleach world.

"I'm invincible?"

Erin blinked, somewhat incredulous that he now possessed power comparable to Hyosube Ichibei.

Chapter 131: An Invitation from Squad Zero?

Hyosube Ichibei's essence is "black," and all the "blackness" in the world is his power.

In the battle with Yhwach more than a hundred years later, Yhwach's "usurpation of the altar" only took away Hyosube Ichibei's "black" for a moment, and the darkness of the world returned to Hyosube Ichibei, restoring his power.

And now, Erin is similar to Hyosube Ichibei.

However, Hyosube Ichibei's essence is "darkness," while Erin's essence is "sword."

All the swords in the world are made of Erin's power.

Spanning the past and the future, as long as the concept of "sword" exists in the world of the Grim Reaper, Erin's power will not be taken away by Yhwach.

Sensing the "sword" slowly gathering within his own protective barrier, Erin nodded in satisfaction.

Finally, his Reality Marble grew up and became a mature Reality Marble, capable of seeking out more swords to make himself stronger.

In addition to collecting all the swords in the world, Unlimited Blade Works, after merging with the Gate of Babylon, has also had its ability to throw weapons greatly enhanced.

After all, the "Gate of Babylon" itself has the means to throw weapons like arrows to attack enemies.

After fusing with Erin's Zanpakuto, it completely overshadowed Erin's inherent barrier throwing technique.

After all, the weapons thrown by Erin's inherent barrier can only open the interface of space from one direction to throw the "sword".

"Gate of the King" can open up space from all directions without any blind spots, allowing for saturation bombardment of the enemy.

In addition, the throwing speed of Unlimited Blade Works is fixed, while the throwing speed of Gate of Babylon is related to the user's level and the level of the weapon.

The higher the level of the "Golden Gate of Babylon," the faster and more powerful its thrown weapons become.

The higher the weapon's level, the faster it can be thrown, and naturally, the more powerful it will be.

If we use the Type-Moon ranking system to classify the Zanpakuto currently possessed within Erin's Realm Marble, the Zanpakuto of ordinary Shinigami and elite Shinigami are classified as D-rank weapons, numbering over ten thousand.

The Zanpakuto of the seated officials are C-rank weapons, and there are more than five hundred of them.

The Zanpakuto of the vice-captain level are classified as B-rank weapons, and there are approximately three hundred of them.

Zanpakuto capable of Bankai at the captain level are classified as Rank A weapons, and their numbers are less than one hundred.

The Zanpakuto that holds the title of "strongest" belongs to the A++ rank and there are about thirty of them.

So far, Erin only has one "EX" level weapon, "Avalon".

This is enough to upgrade the "Golden Gate of Babylon" to Grade A.

In other words, when Erin uses the "Gate of Babylon" throwing weapon to attack, the power of each strike is no less than that of a full-force attack from a captain-level expert.

If a Zanpakuto of the Seat rank is used for throwing, it can be comparable to an attack launched by a Captain after Shikai.

Similarly, a vice-captain's Zanpakuto throw is comparable to a captain's attack after Bankai.

A captain-level Zanpakuto throw is comparable to an attack performed by a captain after a hundred years of Bankai.

The throwing of the "strongest" Zanpakuto is comparable to the attack of Captain-Commander Yamamoto's Bankai.

"Now, all I want to say is, who else?"

Erin pulled his Zanpakuto, which had turned completely golden, from the mound and roared loudly.

After indulging in his rage, Erin sheathed his Zanpakuto back into the mound and regained his composure.

Admittedly, with the power of his Zanpakuto, he could indeed be called "invincible" in the Bleach world, but this awakened Erin's even greater ambition.

He also wants to see more of the world.

Having achieved unparalleled power, let's continue to make ourselves "unparalleled" in other areas as well.

Whether it's swordsmanship, Shunpo (flash step), Hakuda (half-hit fighting), or Kido (demon arts), I must cultivate them to their peak, and then break through that peak!
