After retiring from the Zero Division, Aizen came to study

For ordinary Shinigami, Hueco Mundo is an extremely terrifying place. This is the base camp of Hue, and there is a forest of Daxu in it, where a large number of Daxu live.

But for the captains of the Gotei 13, especially those powerful captains, Hueco Mundo is actually not as scary as imagined.

Daxu is divided into three levels.

Although Vastod has the strength to compete with the captain, as long as the captain is strong enough, he can still defeat Vastod, and there are not many such Hollows even if he goes through the entire Hueco Mundo..

In the final analysis, Xu's method of becoming stronger has too much randomness and relies on devouring souls to obtain evolution. Even if a large number of souls are devoured, the rate of being able to evolve to Vastod is extremely low.

Not so with Death.

The God of Death has a"850" systematic training method. As long as he practices step by step, he can gain considerable strength. If the genius among them masters the swastika, he can even achieve captain-level strength. Comparing Hueco Mundo's Virtue.

Even after becoming the captain, you can continue to practice.

Because if they are divided according to the level of spiritual power, that is, the level of spiritual power.

The captain only corresponds to the first three levels.

The third level belongs to the captain, and the first level also belongs to the captain.

But Xu is not like that.

After advancing to Vastod, it is extremely difficult to progress further.

Hollows evolve by devouring their own kind.

Only when a large number of Kilians devour each other can they evolve into Yachukas. Only when Yachukas devour multiple people of the same kind can they have a small chance of evolving into Vastodo. However, after reaching Vastodo, this level of Hollows, There are only a few in Hueco Mundo, so it is simply unrealistic to rely on devouring them to evolve.

Don't look at it. Over the years, the death rate has been very high when facing the void, and even the captain has died in the battle.

But in fact, none of the really powerful veteran captains took action.

If the Soul Society is really willing and chooses to come out in full force, it can completely destroy Hueco Mundo.

But for the sake of the balance between souls, I didn't do this.

Aizen also knew these things after he became the captain of the fifth division. The same was true. He was very surprised when he learned from Xianye that there had been a Hollow who defeated the young Captain Yamamoto and entered the Spirit King Palace.

Although this head Xu still died in the end.

But he has proven his power and also confirmed Xu's upper limit.

While Aizen's thoughts were flowing, Xianye continued:"After the monk killed the Hollow, his body was taken by Nigeya Wang Yue and made into a Zanpakutō. Now that knife is stored In Team Zero. It was also after that incident that the monk realized that there must be enough obstacles where Team Zero and the Soul King Palace are located. Only in this way can we prevent those messy guys from intruding. Entering the Soul King's Palace"

"This is also the origin of the seventy-two layers of barriers leading from the Soul King Palace to Soul Society!"

"Seventy-two layers of barriers?"Aizen heard another very important message.

"Yes."

Xianye looked at Aizen and told him the truth,"The seventy-two-layer barrier is the barrier between Soul King Palace and Soul Society. You can understand each layer of barrier as a boundary. The spaces between the layers of barriers are chaotic and disorderly. Their existence is stronger than the soul-shielding membrane of Soul Society. Ordinary means may be able to break through one or two layers of barriers, but if you want to break through these seventy-two layers of barriers, , simply impossible"

"Because the power to shape this barrier comes from the Spirit King"

"Under normal circumstances, members of the Zero Squadron come down with the help of the Tianzhu Chariot, which is a unique teleportation device of the Zero Squadron. They first move in the Spirit King Palace and temporarily open a gap in the seventy-two-layer barrier. The Tianzhu Chariot follows suit. Looking at that gap can help them quickly enter Soul Society."

"Then, he also returned along the gap."

"But without the help of people from Division Zero to open the gap in the seventy-two-layer barrier, people from the lower world can only borrow the power of another thing if they want to enter the Soul King Palace."

"what?"Aizen's tone couldn't help but become anxious.

After so many years, it stands to reason that he should have become more stable, but stability comes from knowing. Because he knows many secrets, he looks like he has the pearls of wisdom in his hand. Really When encountering unknown things, Aizen will inevitably be curious.

Team Zero, after learning its secret from the master, has been regarded by Aizen as his future enemy.

If he continues to evolve, sooner or later one day , he has to face Team Zero and the Soul King.

Naturally, he is also very concerned about how to get to the Soul King Palace.

"King key!"

Xian Ye said two words:

"Wang Jian……"Aizen whispered these two words softly. This was the first time he heard of this thing. He didn't know what it was specifically, but literally speaking, it seemed to be related to the Soul King.

Xian Ye continued:"When the Death God is promoted to the Zero Division, the first thing is to accept the baptism of the Spirit King's power. At that time, the Spirit King's power will reshape the body and bones of the Death God who comes to the Spirit King Palace, so that the Death God has The ability to be immortal, as long as the Soul King's Palace is still there, it itself will not die, and this body and bone shaped by the power of the Soul King is the King's Key"

"Because the seventy-two layers of barriers are created by the power of the Spirit King, when the body and bones of the God of Death are all created by the power of the Spirit King, he can easily blend into the seventy-two layers of barriers, pass through them without any hindrance, and reach Spiritual Palace."

"Of course, if you want to create the King Key, you can't do it only in the Spirit King Palace."

Xianye glanced at Aran and said this again.

Aizen's eyes flickered, and he recorded Xianye's words in his mind, and then asked Xianye:"What should we do?"

It's a pity that Xianye didn't answer this question.

Seeing that he couldn't get an answer from his master, Aizen asked Xianye another question,"Master, you were once a member of the Zero Division, so, master Do you also have the King Key?"

Xian Ye answered this question,"I did have this thing in the past, but don't think about it now. After leaving the Zero Division, all the power of the Soul King has been taken away from me."

"So now I can’t enter the Soul King’s Palace."

"That's it!"There was a hint of regret in Aizen's words.

The yellow sand was long, and soon, the two figures disappeared into the depths of the desert.
