The Power of Decay

"Wait, who gave you permission to leave?" Ye Yang asked with a smile, a mocking expression on his face.

The Menos Grande's expressions changed. "Does Your Excellency intend to detain us? I'm afraid you don't have the ability to keep us all here. If even one of us returns, the Emperor will not let you off the hook, and the entire Las Noches will become your enemy!"

Ye Yang chuckled lightly, saying nonchalantly, "A threat? Unfortunately, I know nothing about your so-called Great Emperor, nor do I know his strength. If he came himself, perhaps it would be somewhat useful. But your invoking the title of Great Emperor is like farting to me."

A group of Menos Grande were instantly enraged. "How dare you insult the Great Emperor! We will tear you to pieces!"

"Is that so?" Ye Yang laughed. "There's one more thing you're mistaken about. I have more than enough power to keep you all here."

"Spread out and retreat! Hmph! We will definitely take revenge one day!" After saying that, all the Menos Grande fled in different directions. Ye Yang took out his Zanpakuto and slowly said, "Bankai! Spatial Domain!" In an instant, a flash of silver light appeared, and all the Menos Grande, including Ulquiorra, were pulled into Ye Yang's own space.

Upon seeing that he had moved to a different place, Menos Grande exclaimed, "Where is this?"

Ulquiorra, however, was still suppressing his injuries and had no time to look at these things.

At that moment, Ye Yang's ethereal voice echoed from all directions, "Welcome to my domain. Here, I will rule everything. Here, I am a god!"

The Hollows panicked, looking around in alarm. But the leader, the Menos Grande, had to remain calm. He shouted, "Don't panic! There can't be a limit here, as he says. We need to break through that limit to get out!"

Ye Yang couldn't help but glance at him again, because what he said was true. Although this Spatial Domain belonged to Ye Yang, and he could at least remain invincible within it, this space had an energy tolerance limit. If someone used a special move or someone's Spiritual Power exceeded the space's tolerance, then they could forcibly break the space. Moreover, if the space was shattered Ye Yang would also be injured.

But can they do it? Clearly, they don't meet the requirements. Ye Yang said, "I must say you're very clever; it's good that you thought of this. But you don't have the capability; it's all just empty talk."

"Quick, let's use Cero to shatter this space!" As soon as he finished speaking, all the Menos Grande began to gather Cero, and crimson Cero gradually formed. Then, more than twenty Cero were launched at Ye Yang. Ye Yang did not move, but simply made a light swipe with his right hand. Then, a pitch-black Spatial Rift appeared in front of him, and the more than twenty Cero were completely swallowed up.

They were merely low-level Adjuchas, and even the leader was only a mid-level Adjuchas. To shatter this space, one would need at least the power of Vasto-class Menos Grande, and it would have to be Menos Grande who had been promoted to Vasto Lorde for many years. Otherwise, trying to shatter this space was simply a pipe dream!

"How is this possible..." The Menos Grande watched in despair as their Cero was devoured, with no chance to retaliate. Just then, Ye Yang suddenly disappeared. The next moment, he appeared behind the leader, his right hand slicing across his body with the power to tear through space. The leader looked at Ye Yang in disbelief, wanting to say something, but he had no time to speak. His body was split in two and disappeared into the air.

Ye Yang muttered to himself, "Did you think I only have this one way to attack? This is my space; I can ignore spatial distances here. So, who's next?"

With their leader dead, the remaining Menos Grande were thrown into chaos. Seeing that their leader couldn't even withstand a single move from Ye Yang, they were filled with despair and began to flee in all directions.

All of this was useless. The entire space belonged to Ye Yang; where could they run to? What followed was a one-sided massacre! In a short while, the Menos Grande, with their desperate roars, were completely wiped out by Ye Yang.

After clearing them out, Ye Yang went straight to Ulquiorra's side. Ulquiorra was still healing his injuries. Ye Yang had been so focused on fighting the Menos Grande that he hadn't paid close attention to his injuries, but now that he was closer, he couldn't help but gasp! A black substance was eroding his body around his Hollow Hole, but strangely, it couldn't penetrate him any further. The black substance didn't damage his body at all. Then, new flesh grew back, replacing the flesh eroded by the black substance, and then the black substance would erode the new flesh again, forming a vicious cycle.

Ulquiorra regained consciousness and looked at Ye Yang with the same unchanging expression. "Grim Reaper, why did you save me?"

"Because I want you to do me a favor, which means I want to cooperate with you," Ye Yang stated his purpose without any hesitation. Lying to him would eventually be exposed, so it was better to be straightforward.

Ulquiorra simply said three words: "I am a Hollow!"

Ye Yang smiled and looked at him, "Who said that Shinigami and Hollows can't cooperate?"

Ulquiorra fell silent at this point, and Ye Yang, without being impatient, waited patiently for his reply. After a long while, he finally spoke, "Speak, how about cooperation?"

"It's very simple. I'll heal your injuries, and you'll do something for me," Ye Yang said slowly.

"What's up?"

"I need you to help me monitor a Shinigami named Sōsuke Aizen. You don't need to know the reason. How about it? A fair deal, right?" Ye Yang said with a smile.

Ulquiorra said, "The Grim Reaper? He's in Hueco Mundo?"

Ye Yang waved his hand. "You don't need to go looking for him. He'll come looking for you."

His face remained completely expressionless; trying to glean anything from it was virtually impossible. Ulquiorra, though unsure why Ye Yang had made this strange request, agreed nonetheless; to him, it was nothing more than a "deal!"

Ye Yang's lips curled up when he saw that Aizen had agreed. "Aizen, you never expected this, did you?"

"Let's treat your injuries first," Ye Yang said, carefully observing the black mist. Although he didn't know what it was, Ye Yang sensed a faint familiarity with it.

Ye Yang asked, "Ulquiorra, could you tell us how you got this injury?"

He replied expressionlessly, "Baraggan was injured."

"Oh? You mean that Hueco Mundo King Emperor Baraggan? Do you know what this black aura is? It feels like corrosive power, but it's not. What is it?" Ye Yang was also confused. He had never seen this kind of power before, but he had a sense of déjà vu deep in his soul.

He glanced at Ye Yang, seemingly doubting Ye Yang's capabilities, "Ignoring corrosion is decay, it's the erosion of time."

"What!" Ye Yang was shocked. Decay! It was actually the power of decay, which in other words was the power of time. This power even surpassed space. Although decay was only one kind of power of time, it was still incredibly powerful. The power of time, the erosion of years, was absolutely impossible to remove unless one possessed the same power! He never expected that Hueco Mundo would have a Hollow with such power. No wonder he called himself the King of Hueco Mundo!

Ulquiorra continued, "What's wrong? Is there no way?"

"There are ways," Ye Yang said, "But I'm very curious, how did you resist the erosion of time? That kind of power is enough to kill you!"

"High-Speed Regeneration! My greatest power is not fighting, but regeneration," Ulquiorra said slowly.

Ye Yang suddenly realized why. Having the ability of High-Speed Regeneration could indeed temporarily resist the power of decay, but this was not a long-term solution. He couldn't use his power all the time, especially now that he was being chased by others, which was very dangerous. He had to save enough Spiritual Power to use High-Speed Regeneration.

"I see. Although I cannot completely heal your injuries, I can suppress them, but there is a time limit. There's no way to completely limit the power of time, not even space."

"How do I do this?" Ulquiorra, his face expressionless but inwardly pleased. After all, this thing had been tormenting him constantly. Although it couldn't be eradicated, it could be contained, at least sparing him from further suffering.

Ye Yang said, "It's simple. I can seal it for you, but it won't last long. It can only last for a year. After a year, you'll need to come back to me to reinforce the seal, otherwise there's no other way."

"Alright, let's begin."

Ye Yang began preparations. This was all he could do so far. The power of time could only be countered by time itself, but the power of space was not much different. People often put time and space together. Why? Because only space could be compared to time. Although time was superior to space, it was not absolute.

Baraggan wields the power of decay, is nowhere to be found, while Ye Yang is right here. In other words, this black energy is uncontrolled. Doesn't he believe he can't subdue an inanimate object?

Ye Yang brought his right hand close to the ball of black energy and chanted, "Spatial Stasis!" A flash of silver light appeared in Ye Yang, and the ball of black energy stopped moving, temporarily halting its corrosive influence, as if it had been frozen in place.

However, this was ultimately a decaying force, and it soon began to move slowly, as if trying to break free from its constraints. How could Ye Yang allow it to succeed? He clasped his hands together and chanted, "Spatial Confinement, Seal!" A streak of silver light shot into the black mist, and the black mist immediately ceased all activity.

Before it could recover, Ye Yang quickly continued the sealing, his hand forming a sword-finger gesture, "Spatial Seal, Stabilize!" The black energy was then enveloped by a silver ball of light and slowly entered Ulquiorra's body...
