People are in death, unlimited sword control at the beginning.

Over the course of hundreds of thousands of years, these Zanpakutō have experienced several masters, and have gained great reputations. Each has become the "strongest" in its own field, leaving behind its own legend.

Later, Nimaiya Oue's forging skills improved to a higher level. He no longer used powerful souls to forge finished Zanpakutō, but only made the semi-finished Zanpakutō-Shata.

Such semi-finished shallow fighting requires the Shinigami themselves to practice "sword Zen" and use their own souls to nurture the "spirit" in the shallow fighting and make it grow.

When the spirit of Qian Da is mature, Qian Da will be promoted to a "Zanpakutō".

In order to cover up the darkness of the birth of the original Zanpakutō, the Central Room 46 issued a strange order - no two identical Zanpakutō are allowed to appear in the same era in Soul Society.

This is because the Zanpakutō that was bred by Asata himself has all kinds of abilities. Without two identical souls, naturally, there cannot be two Zanpakutō that are exactly the same.

However, the first batch of "strongest" Zanpakutō can choose their own masters. As long as they have a certain degree of compatibility with them, these Zanpakutō will respond with death and become their Zanpakutō. .

If the same two Zanpakutō appear in the same era, the truth that "Zanpakutō is conceived from the soul of the God of Death, born and dies together with the God of Death" will be exposed.

In order to prevent the reputation of the "God of Swords" Nikaiya Wang Yue from being damaged, the nobles of the Seireitei would never allow such a situation to occur.

If people knew about the existence of this world, there would be absolutely no place for Captain Ayrin in Soul Society.

but……

After looking at the swords in this world, Aizen also knew that such a situation would be almost impossible.

Because even if they don't use the Zanpakutō that appears in the hands of the Shinigami in this era in Soul Society, there are still a large number of powerful Zanpakutō waiting for that man to use.

However, looking at the nine Zanpakutos flying out, Aizen still couldn't understand.

Why is there even a hollow Zanpakutō in this world?

Could it be that, as long as it is a weapon, Captain Aylin can make it in this world?

……

Two vice-captain-level Zanpakutō, four captain-level Zanpakutō, and three hundred-year captain-level Zanpakutō increased Aelin's spiritual pressure.

Now, among the "swords" in the entire Shinigami world, the only ones that can significantly increase Aelin's spiritual pressure are the Zanpakutos of the Zero Squadron.

Therefore, Aylin does not spend much time on lottery drawings every day now.

More importantly, he made the weapons in his memory based on his existing sword-making experience.

Any weapon that can be remembered by Aylin is at least a Zanpakutō that is above the level of a chief officer. It can bring Aylin an improvement much faster than drawing a lottery.

Aizen, who was sealed and hung on the cross, just watched Zanpakutō being made one by one by Aelin.

Every time a Zanpakutō is made, Captain Aylin's spiritual pressure will increase a little.

This terrifying speed of improvement was even faster than the speed at which he reached the ultimate limit of death with Bengyu's help.

Moreover, he has not made any progress in the Death God's limit for many years. He can only test the Death God's virtualization many times to complete the Bengyu in his hand, and use the power of the Bengyu to allow himself to break through the Death God's limit.

But the spiritual pressure in Aylin's body had already exceeded the limit of the Death God.

It's as if Captain Aylin has no so-called "bottleneck" at all.

In fact, it does.

In the entire world of Death, the upper limit of cultivation has been locked. The limit of Death is the strongest state that living beings can reach.

Even if this limit is exceeded with the power of the King Key, Zanpakutō, or Holy Monogram, the gap in spiritual pressure will not be huge. In many cases, the outcome of a battle still depends on the compatibility of the abilities of both parties.

There are only three people in this world who can continue to progress after breaking through the limits of death.

Yhwach, the Ichibei of the Military Chief, and Aelin.

The Spirit King does not count.

The Spirit King is conceived by the will of the world, and is at its peak at birth.

For more than a million years, the Soul King has been weakened by the Tsunayashiro family, but despite this, the Soul King who has now become a human pig is still the strongest existence in the Shinigami world.

A ray of will can make the world move forward according to the future he foresees.

Yhwach, the ancestor of the Quincy, as long as there are Quincies in this world, Yhwach can activate "Holiness" at any time to take back all the power of the Quincy to strengthen himself.

Moreover, as the "Son of the Soul King", Yhwach can also absorb the power of the Soul King for his own use.

It can be said that as long as the Quincy exists in this world, Yhwach's strength can be improved to a level comparable to the Soul King.

Unfortunately, the Empire of Light was severely damaged by the Gotei 13 led by Yamamoto Genryusai Shigekuni a thousand years ago. Yhwach, who was partially defeated by Ichibei, the military commander, used the right arm of the Soul King to seal away some of his power, was severely damaged by Yamamoto Genryusai. Guo was almost killed, and he hid in the shadow of Seireitei. He only regained consciousness not long ago, and his strength has not yet been restored.

Ichibei, the military master, is essentially "black". As long as the concept of "black" still exists in the world, he can absorb power from all the "black" in the world.

However, the Ichibei of the Military Master Division has existed for more than a million years, and his power has reached its peak.

He is truly the strongest person under the Spirit King.

Even with his power, he can name the "Spirit King Candidate" as "Spirit King" through his own ability, allowing him to possess the power of the Soul King.

Of course, in the case of Ichibei, the military chief, the so-called "power of the Soul King" is nothing more than a "wedge that stabilizes the world."

Sora's huge power is ultimately used to stabilize the world's "existence", not just the original "Spirit King".

Similarly, Aelin's essence is a "sword", and he can gather the power of all "swords" in the world into one body, allowing himself to reach the level of a military master.

Not only that, the "swords" of the Death God World can elevate Ayrin to a level comparable to that of Ichibei, the Soldier Master, but those swords outside the Death God World can allow Ayrin to go further on this basis and surpass the Soldier Master. Ichibei Ibei even surpassed the level of the Soul King.

Of course, because Aylin has not yet unleashed the abilities of all the swords in the Unlimited Sword System, there is still some distance between Ayling and the Ichibei of the Weapon Master.

But at the very least, there is a qualitative gap between Aylin and others now.

Already standing in the same realm as Yhwach and Ippei of the Military Chief Division.

Aizen still can't understand Aylin's realm, but that doesn't mean that he can't see that there is a dimensional gap between Aylin and himself and others.

In other words, he felt that Aylin was already in the realm of "gods" in some respects.

Although Aylin feels that his strength is enough to rank among the top three in the world of Death, he will not underestimate other people in the World of Death because of this.

Especially scientists.

Urahara Kisuke counts half.

Nirvana, count as one.

After Urahara Kisuke was exiled from Soul Society, although he would invent some things, he put more energy into improving his strength.
