The BOSS Appears (2)

It's Kisuke Urahara and Tessai Tsukabishi.

Their arrival disrupted the balance in the valley. Kisuke Urahara quickly analyzed the battlefield situation, while Tessai Tsukabishi began preparing a wide-ranging Kidō technique in an attempt to control the situation.

"Time stops—'Stop, Sand of Time!'"

Tessai Tsukabishi's voice echoed through the valley, and a powerful force of time began to spread, attempting to freeze everyone on the battlefield. But Aizen seemed to have been prepared; his figure mysteriously vanished before the force of time could reach him.

"Spatial Transfer - 'Move, Boundary Trace'!"

The second Kidō followed closely, enveloping the eight people who had fallen into the Hollowfication within a massive spatial sphere. Tessai Tsukabishi attempted to move them away, but Aizen's figure reappeared, slashing at the spatial sphere with his sword.

"Clang--!"

The sound of metal clashing echoed through the valley. Kisuke Urahara stood in front of Aizen, his Benihime clashing with Aizen's Zanpakuto, sparks flying.

"Lieutenant Aizen, this is enough." Kisuke Urahara's voice was calm yet firm. "You've done enough."

Aizen looked at him, his smile widening. "Captain Urahara, you've finally arrived. I've been waiting for you for a long time."

"Wait for me?" Kisuke Urahara frowned. "You knew I would come?"

"Of course." Aizen sheathed his sword and stepped back, his demeanor as composed as if he had anticipated everything. "I knew you would come, and I knew that the Great Kidō Chief would come."

"Why?" Kisuke Urahara asked. "Why would you do something like this? Hollowfication Experiments are taboo, you should know that. And Captain Hirako... aren't they your comrades?"

"Comrades?" Aizen laughed, a hint of mockery in his smile. "Captain Urahara, you're still too naive. In this world, there are no eternal comrades, only eternal interests. What I do is for a greater goal—to break the boundaries of Soul Reaper and create new possibilities."

"At the cost of your comrades' pain and sacrifice?" Kisuke Urahara's voice was filled with rage. "Aizen, you've gone mad."

"Are you crazy?" Aizen shook his head. "No, I just see further than you. Captain Urahara, you're a researcher too, you should understand—progress always comes at a price. And they are the necessary price."

Before he finished speaking, his figure vanished again. The next second, he reappeared beside the spatial sphere and slashed down with his sword.

"Don't even think about it!" Tessai Tsukabishi roared, maintaining the Kidō incantation with all his might.

However, Aizen's sword was too fast and too sharp. A crack appeared on the spatial sphere. Although it was quickly repaired, a small amount of Hollowfication Reiatsu had already leaked out.

"It's useless." Aizen's voice echoed through the valley. "Your rescue is doomed to fail. However... I'm quite curious to see how you'll deal with these 'Hollowfication Soul Reaper'. Captain Urahara, you're a genius, I believe you'll have a way."

After saying that, his figure completely disappeared into the night, leaving behind only a meaningful sentence. "We will meet again. Next time, I hope you can show me something even more interesting."

After Aizen left, the tense atmosphere in the valley eased slightly. But an even bigger problem lay before Kisuke Urahara and Tessai Tsukabishi —the eight captains and Lieutenant who had fallen into Hollowfication were in extremely unstable states and could completely spiral out of control at any moment.

"How long can the Great Kidō Chief of the Rhombus-shaped Stone?" Kisuke Urahara asked.

"At most a quarter of an hour." Tessai Tsukabishi's forehead was covered in sweat. "Their Reiatsu is too strong, and the Reiatsu after Hollowfication is even more violent. I have to maintain it with all my might to ensure the spatial sphere doesn't collapse."

Kisuke Urahara quickly considered a countermeasure. Just then, two figures emerged from the shadows.

It is Liu Ziyun and Unohana.

"You..." Kisuke Urahara looked at the two who had suddenly appeared, a hint of surprise flashing in his eyes, but he quickly regained his composure. "Why didn't you make a move earlier? If you had, you might have been able to capture Aizen."

"That's why we came out here." Liu Ziyun didn't explain further, cutting straight to the point, "After you take them back, try treating them with the Hōgyoku. You need to approach the treatment with the absolute determination to cure them—even though the result might feel like a failure, it's a necessary process. Otherwise, it will definitely fail."

Kisuke Urahara frowned. "The Hōgyoku? How did you know?"

"You'll find out," Liu Ziyun said without going into details. "Then Aizen will frame you as the masterminds behind this Hollowfication Experiment. The Central 46 might even sentence you to the death penalty—but that's alright, just have Yoruichi take you to the World of the Living. I'll tell you the rest when I get World of the Living. There's no time now."

He paused, his tone becoming more serious. "Remember, you must bring that Hōgyoku to the World of the Living. I'll tell you its specific uses later. Also, Captain Unohana and I will stay out of it—we'll explain this to the Captain-Commander as well. Don't worry, there won't be any pursuers, but we'll put on a show for Aizen."

Having said that, he didn't give Kisuke Urahara a chance to ask further questions, and gave Unohana a wink. "Let's go."

The two figures flashed and disappeared into the night once more, their speed so fast that they left no afterimage.

In the valley, only Kisuke Urahara and Tessai Tsukabishi remained, staring at each other in bewilderment.

"It seems we've gotten ourselves into something serious," Kisuke Urahara shook his head with a wry smile. "It looks like they all know, but have to keep it a secret for some reason. Sigh..."

"So now..." asked Tessai Tsukabishi.

"Do as he says." Kisuke Urahara a deep breath. "Although we don't know who that person is, judging from his ability to accurately predict Aizen's actions, he knows far more than we do. Right now, saving lives is the priority."

The two worked together to stabilize the spatial sphere, and then quickly moved towards the direction of the Twelfth Division.

Meanwhile, Liu Ziyun and Unohana have returned to Seireitei.

Instead of returning to the Fourth Division, they infiltrated the Second Division Barracks. As the headquarters of the Commander-in-Chief of the Stealth Force, the Second Division's defense system was one of the strongest in Soul Society, but it was rendered useless by Liu Ziyun's Black Cloak and Unohana's strength.

The two appeared silently in Yoruichi Shihōin's office.

"Who?" Yoruichi Shihōin turned around alertly, her hand already on her Zanpakuto. But when she saw that it was Liu Ziyun and Unohana, she paused for a moment, then relaxed her guard.

"Why... are you here?" Yoruichi Shihōin asked, her eyes filled with doubt. "Have you finished your business?"

"Not yet, but soon," Liu Ziyun said directly. "Next, you'll prepare to meet up with Kisuke Urahara. Take his experimental equipment and all those Hollowfication captains Lieutenant with you. Once Kisuke Urahara's trial is over, take them to the World of the Living to hide. After some time, I'll find an opportunity to come to the World of the Living to find you and explain the details."

Yoruichi Shihōin's expression turned serious. "Did you all know this would happen? Did we really have to flee Soul Society? This is no small matter—once we're labeled as deserters, we'll never be able to come back."

"Yes, we know." Liu Ziyun didn't hide anything. "But we have no choice but to do this. I'll explain the specific reasons to you in the World of the Living later. We're not abandoning you; we have unavoidable reasons—the matter is too complicated to explain all at once. We were also afraid that knowing these things beforehand might cause some unnecessary problems, which is why we didn't explain it to you clearly."

He looked directly into Yoruichi Shihōin's eyes. "Once you leave the vortex of Soul Society, we will be able to tell you. Believe me, this is to protect you, and also to protect the future of many more people."

Yoruichi Shihōin remained silent for a long time. As the Second Division Captain, she had her own pride and responsibility. But she also knew that Unohana and Liu Ziyun wouldn't do such a thing without a reason. Moreover, judging from Liu Ziyun's previous prophecy, he seemed to really know some fragments of the future.

"Alright." Yoruichi Shihōin finally made her decision. "We'll do as you say. I'll go prepare now."

"Okay, go ahead." Liu Ziyun. "Don't be alarmed by anything that happens afterward. Remember, the most important thing is to take them to the World of the Living and live a quiet life. If things go wrong, the consequences will be unimaginable. We need to go back too."

After saying that, he and Unohana turned and left, disappearing into the night once again.
