Death: Captain Millennium

Lin Yu and Aizen's spiritual pressure erupted like a volcano, their spiritual pressure like a surging tsunami, instantly destroying the barrier they had set up at the beginning of the battle. This powerful spiritual pressure shook everything around, as if it was going to draw the whole world into it.

As their spiritual pressure was fully released, the figures of the two gradually became blurred, and their auras became stronger and stronger. Lin Yu's eyes became sharp, and the purple sword in his hand flashed with dazzling starlight; while Aizen smiled, his eyes revealing confidence.

The powerful spiritual pressure of the two enveloped the entire town of Karakura, suffocating everyone. Shinigami, the Masked Army, and the Quincies, among other factions, were all stunned and stunned by the overwhelming spiritual pressure. They felt an unprecedented sense of fear, a feeling that made them realize that something was amiss in Karakura, that two incredibly powerful beings were facing off.

In the face of this powerful spiritual pressure, the buildings in Karakura Town began to shake, but the streets were empty. It was not that humans did not want to escape, but that they were all oppressed by the spiritual pressure and fainted.

Urahara Kisuke and his companions were the closest to Lin Yu. They were very sensitive to spiritual pressure and the moment the barrier was broken, they noticed the owners of the two powerful spiritual pressures - Lin Yu and Aizen Sosuke.

"How could this happen? Lin Yu actually confronted Aizen? This is bad, things are becoming very tricky." Urahara Kisuke frowned, a look of worry on his face.

The masked army members in the distance were even more furious, especially Hirako Makoto. His hands were shaking uncontrollably, and his eyes were burning with rage: "Aizen! This abominable guy finally made me feel his abominable spiritual pressure again."

Ryugen Ishida, who had been scared away by Lin Yu before, now looked extremely pale. He remembered the terrifying pressure he felt when he fought with Lin Yu just now, and couldn't help muttering to himself: "Is this the strength of the captain just now? It's too strong. Fortunately, he didn't mean to kill me at that time. But he saw that the other party was wearing the same clothes. Could it be that there was a civil war in the Soul Society?" Thinking of this, Ryugen Ishida was shocked and confused.

Lin Yu and Aizen stood facing each other, the space around them distorted by their spiritual pressure. Their eyes met, sparks flying in the air.

"Captain Lin Yu, your strength is really not to be underestimated." Aizen said with a smile, a hint of excitement in his tone.

"Aizen, today is the day you go to hell." Lin Yu showed no sign of weakness, the Ziwei sword in his hand flashed with cold light.

Before he could finish his words, the two men attacked simultaneously, their spiritual power surging and their swords wielding blades. Their battle was fierce, each strike imbued with immense power, causing the surrounding buildings to collapse.

When people from all sides arrived at the scene, they were shocked by the scene.

After a few rounds of fighting, Aizen was very impressed by Lin Yu's slashing technique. He secretly sighed in his heart: "This guy can actually use the slashing technique to such perfection, it's really not easy!"

"As expected of you, a veteran captain who has held the position for more than three hundred years. I admit that I am not as good as you in slashing techniques. Maybe even Kenpachi Zaraki is not as powerful as you. Among all the slashing techniques I have ever seen, I would call it the strongest!" Aizen exclaimed with an expression of admiration on his face.

Lin Yu smiled slightly, the sword in his hand flickered with starlight, and said, "Thank you for the compliment, Aizen. But this is far from enough!" After that, he swung the sword at Aizen again.

The two men exchanged blows, their swords flashing and shadows intersecting, each clash emitting a sharp sound of metal clashing. The air around them seemed to be shaken by their momentum and became solemn.

Lin Yu's eyes were focused. He knew that he had to go all out when facing a strong man like Aizen. He kept adjusting his breathing and rhythm, striving to bring his slashing technique to its full potential.

Aizen remained calm and composed throughout the fight. He carefully observed Lin Yu's movements, looking for his opponent's flaws. However, Lin Yu's offense and defense were so tight that it was difficult for him to find an opportunity.

"Aizen! If this is the limit of your skills, then it's over."

"The Seventy-Eighth Breaker! Cutting the Hua Lun."

With Lin Yu's angry roar, he swung the Ziwei sword in his hand violently. A huge sword energy came out of the sword and slashed towards Aizen with powerful power.

Lin Yu then took a step forward, this time using his unique instant step technique - instant flash. His strange and swift steps made it difficult to predict his direction of movement.

Just as Aizen was resisting Hado, Lin Yu appeared behind him like a ghost.

Without any hesitation, Lin Yu swung his sword, and the sharp sword instantly cut into Aizen's body.

Aizen's face was pale, but his expression was cheerful. He didn't seem to care about the deep wound on his body. Blood gushed out from his back, staining his white captain's haori red, making it particularly eye-catching.

"Captain Lin Yu, you're really good." Aizen said with a smile, a hint of admiration in his tone. However, his next words shocked Lin Yu: "But, are you sure it was me you just hit?"

Lin Yu's pupils contracted slightly, and a sense of foreboding welled up in his heart. At this moment, he suddenly felt a sharp pain in his chest. A wound quickly appeared, and blood gushed out like a fountain. This was his first injury in this battle, and it was serious.

It turned out that the person he hit was Gin Ichimaru who was lying on the ground. Aizen picked him up and used him as a shield at some point. Aizen was not injured at all.

"You... when did you unleash your Zanpakutō?" Lin Yu asked, gritting his teeth while enduring the severe pain. He had always thought he could see through Aizen's movements, but now it seemed that he had clearly underestimated his opponent's strength and cunning.

"When did you think I didn't release Mirror Flower and Water Moon?" Aizen smiled slightly, his eyes full of teasing. He gently waved his Zanpakutō, shaking off the blood on the blade, and then continued to approach Lin Yu with an elegant posture.

Lin Yu widened his eyes. He couldn't believe what was happening before his eyes. Aizen had deceived his perception so easily.

Lin Yu covered his wound and took a few steps back. He knew he was at a great disadvantage, but he would never give up easily.

"Aizen, you are indeed very strong...but I won't fall down like this!" Lin Yu gritted his teeth and prepared to use his final move.

However, Aizen seemed to have anticipated his move. He dodged Lin Yu's attack with a flick of his wrist, and at the same time, he swung his Zanpakuto and attacked Lin Yu again.

Lin Yu tried his best to resist Aizen's attack, but due to his serious injuries, his movements became slower and slower.

At this critical moment, Hirako Makoto, who was watching the battle, stepped forward and blocked Aizen's attack for Lin Yu. "Captain Lin Yu, let me lend you a hand!"

"Hurry up! Aizen has released Kyoka Suigetsu, and you can't tell friend from foe."

As soon as he finished speaking, Hirako Makoto was stabbed by Aizen, and the Lin Yu in his eyes was actually Aizen.
