Murciélago

While they were fighting, Orihime encountered danger. Two female Arrancar Ichigo. Orihime was enraged and swung Zangetsu to rescue her, but Ulquiorra suddenly appeared in front of them, blocking Ichigo's attack and preventing Ichigo from helping Orihime.

Orihime seemed to have some hatred towards the two Arrancar. Ichigo of the Arrancars was tearing Orihime's clothes. Enraged, Ichigo could no longer control himself and threw Getsuga at Ulquiorra. While Ul was blocking Getsuga, Ichigo rushed to Orihime's location to rescue her!

Ulquiorra had already seen through his intentions. With one hand blocking Crescent Getsuga and the other hand gathering Cero, a bright green Cero shot out, instantly shattering Ichigo's plan to go to the rescue.

Just then, Ye Yang appeared beside Orihime. The small fry outside had been mostly cleared out, leaving only a few troublesome Rukia and her allies to deal with them, so Ye Yang came in first.

Ye Yang glanced at them indifferently, "Get lost, before I change my mind." They were the two Arrancar Ye Yang had questioned earlier. Upon seeing Ye Yang, they were immediately terrified and fled as fast as they could in the chaos.

Ulquiorra was also surprised to see Ye Yang enter, but Ye Yang gave him a hint, indicating that he should not speak yet, because the battle between Ichigo and Ulquiorra crucial and could not be interrupted. This would be the most important battle in Ichigo's growth, so Ye Yang chose to let them fight to the end, and then intervene when the outcome was decided.

Ulquiorra then ignored Ye Yang and focused his attention back on his battle with Ichigo. Ye Yang asked Orihime, "Are you alright?"

"It's alright, thank you, Captain Ye Yang," Orihime smiled slightly. However, when she saw Ichigo fighting, she was still a little worried. "Captain Ye Yang, do you think Ichigo can win?"

Ye Yang's expression was somewhat grave. "Although it may sound cruel to you, to be honest, Ichigo's chances of winning are no more than 10%! I've fought Ulquiorra before, and ultimately neither of us could gain the upper hand. His strength is definitely more than what he's showing now; at least he hasn't Resurrección yet."

However, Orihime was not discouraged; the confidence in her eyes remained undiminished. "I believe in Kurosaki-kun; he won't fail."

Ye Yang sighed softly, "Perhaps. Ichigo always manages to surprise others. His victory over Grimmjow was a prime example; he always grows rapidly from battle. Perhaps this time he'll bring us something different again."

The battle between Ulquiorra and Ichigo continued until the Number Ten Espada suddenly arrived. Among the Espada, besides those who had been killed, there were also the first three Espada who had been brought to the World of the Living by Aizen. Currently, only he and Ulquiorra remain in Hueco Mundo.

However, this time he seemed to be much larger than before, but he did not pose a threat to Ichigo, because Ishida, who was right behind him, also came over and devised a plan to throw him out of there.

Without external interference, Ichigo finally got serious. He rested one hand on his face and said, "Then let's begin, Ulquiorra. This is what you've been waiting for, Hollowfication!"

As he spoke, a Hollow mask appeared on Ichigo's face, and his Spiritual Pressure also became extremely violent. He roared and launched an attack. Ichigo's strength after Hollowfication was indeed incomparable. Before, he was being suppressed by Ulquiorra, but after Hollowfication, he completely gained the upper hand.

As they spoke, the two broke through the wall and went outside. The space inside was too small to withstand such a battle. After Ulquiorra came out, he immediately launched a Cero at Ichigo. However, this time Ichigo did not dodge or evade, because there was no need to dodge at all. He simply held his Zanpakuto in front of him and easily blocked the Cero.

Ulquiorra looked around and then made a decision: to fly upwards immediately, because only there could he unleash his power. With Ichigo's current strength, he couldn't defeat him without unleashing his power.

The two continued upwards, and just as they were about to reach the top, Ulquiorra cleaved the roof open with a single slash, landing on the canopy of Las Noches. Ichigo followed him there.

The sky was merely a fabricated illusion created by Aizen. Ye Yang and Orihime emerged and gazed at the gap in the sky. Orihime said to Ye Yang, "Captain Ye Yang, please take me up there. I want to watch Kurosaki-kun fight!"

"Of course you can, but are you sure you want to do that?"

"Hmm," Orihime's eyes revealed a resolute look. Ye Yang did not try to persuade her any further. Taking her up there would only add to the sorrow, because Ichigo was no match for Ulquiorra after his liberation. All they would see was a one-sided massacre.

Ye Yang looked at Ishida and asked, "Are you going up too?"

"Certainly"

"Alright, I'll take you up right away." Ye Yang grabbed one person with each hand and instantly arrived at the canopy of Las Noches. Ulquiorra was standing on a stone pillar. He merely glanced at Ye Yang and the others before turning his attention back to Ichigo.

He said coldly, "Under the canopy of Las Noches, two things are forbidden: one is the Cero exclusive to the Espada — the Gran Rey Cero, and the other is the unleashing of Espada swords of size four and above, because both are too powerful and could potentially destroy Las Noches."

Ulquiorra Zanpakuto at Ichigo and softly chanted, "Seal it off— Murciélago!" Instantly, a black Spiritual Pressure erupted from Ulquiorra's body, as if the originally gray sky had been dyed black. The heavy Spiritual Pressure, like splashed ink, swept over them, and Ishida and Orihime almost couldn't withstand it. Ye Yang gently touched them to block the Spiritual Pressure.

At this moment, Ulquiorra's appearance changed somewhat. The mask that was originally on the side was now on top of his head, and the two tear tracks were much thicker. Most astonishingly, two huge black wings grew from his back. These two wings were the kind of wings that belonged to demons, and they looked extremely terrifying.

"Don't waver, get into position, stay focused, don't let your guard down for even a second!" Ichigo immediately focused his attention, and suddenly a beam of light appeared in his hand. Just as Ichigo was wondering how Ulquiorra would attack, he suddenly appeared in front of him, giving him no time to react.

However, Ichigo still subconsciously used Getsuga Tenshō because he sensed a dangerous aura. Although Ichigo used Getsuga, he was still injured, and the right side of Ichigo's mask shattered!

Ulquiorra, standing behind Ichigo, spoke, "Used Getsuga as a reflex? A wise decision, or your head would be at my feet right now!"

Ichigo stared at Ulquiorra in disbelief. He never expected that Ul's strength would increase so much after being released. Even Ichigo, in his Hollowfication, hadn't reacted at all. Ichigo forcibly suppressed his surprise, wiped his forehead with his right hand, and restored his mask.

"Oh? You've gotten a lot stronger, haven't you? The mask's duration seems to have increased, but it's still so fragile." With that, Ulquiorra threw out the light gun in his hand. Ichigo watched Ulquiorra's movements intently and successfully dodged one of the light guns. However, Ichigo saw a second gun coming straight at him. Unable to dodge, Ichigo chose to avoid vital areas, letting the light gun graz his shoulder.

Next, Ichigo fell into a complete disadvantage. The two were simply not on the same level. Although Ichigo was slightly at a disadvantage when he fought Grimmjow before, Ichigo still defeated him. This means that the two are in the same dimension, which is why Ichigo was able to defeat Grimmjow.

However, Ichigo was too far away from Ulquiorra at that moment, so he didn't even have a chance to counterattack.

Ulquiorra's patience seemed to be wearing thin. He pressed Ichigo down, saying, "Ichigo Kurosaki, use Getsuga now, or you'll die here. That's your strongest move, the one you can use to fight the Espada. Unleash it and let me see your power."

Ichigo stepped back, saying, "Even if you didn't tell me, I would still do it!" With that, he focused all his strength on the Getsuga and struck Ulquiorra's direction, the black Getsuga roaring out!

Ulquiorra, however, neither dodged nor evaded. He simply extended his right hand to block Ichigo's strongest attack, and when the Getsuga disappeared, Ulquiorra was not even slightly injured!

"As expected, it's only at the human level."

Ichigo stared at Ulquiorra in astonishment, exclaiming, "What?! He's completely unharmed!"

Ulquiorra looked down at him condescendingly. "Your black Getsuga does indeed resemble our black Cero."

"Don't compare that Cero to Getsuga!"

"Really? You haven't seen it before, have you?" Ulquiorra stretched out his index finger, and Cero began to gradually condense on his hand. Unlike before, this time it wasn't green, but pitch black. Suddenly, the black Cero out and struck Ichigo directly.

Moreover, Ulquiorra was right. This black Cero is very similar to Getsuga Tenshō, which Ichigo Hollowfication. They are almost identical in terms of Spiritual Pressure and nature. The only difference is their appearance.

This is normal. Ichigo Hollowfication, so his Getsuga naturally has Cero properties. Hirako can also use Cero after Hollowfication, so it's not strange that Ichigo Getsuga is like Cero.

The power of the black Cero was already immense, and Ulquiorra's Spiritual Pressure was much higher than Ichigo's. As a result, Ichigo was directly blasted away, his Ichigo shattered, and most seriously, his mask was completely destroyed! In other words, his Hollowfication state was shattered!
