Death: Captain Millennium

Inside the Gate of Hell, Lin Yu surveyed everything with curiosity. What he saw before him was an endless expanse of white, suspended blocks, a dreamlike scene. Between these blocks, blue roads intersected, as if they were passages to an unknown world.

Hell was filled with an endless miasma, like a thick mist enveloping the entire space. This miasma was suffocating and uncomfortable, and those with weak spiritual pressure would find it difficult to survive here.

"It's truly desolate, even worse than Hueco Mundo," Lin Yu lamented. He couldn't help but think of Hueco Mundo, where he'd been before. While that place was also filled with danger, at least there was a desert. Here, however, there seemed to be only death and emptiness.

At this moment, Lin Yu suddenly felt a slight movement behind him. He turned around alertly and saw a figure quietly appear behind him. Looking closely, he found it was Rukia who had followed him into the Hell Gate.

"Lin... Teacher Lin Yu!" Rukia looked at the face before her, her heart filled with surprise and joy. She had only felt that the figure was somewhat familiar, but had not recognized it as Lin Yu. However, when she saw the face clearly, her excitement was beyond words.

But before she could finish her words, Rukia suddenly began coughing violently. She felt a strong sense of suffocation, as if the air around her had become heavy and oppressive. It turned out that her spiritual pressure had weakened to the point of being unable to withstand the miasma of hell. These miasma, like invisible killers, corroded her spirit body, causing her unbearable pain.

Lin Yu looked at Rukia in front of him, and a complex emotion surged in his heart. He felt distressed and helpless, wondering why this silly child had followed him into hell. He had originally thought that he was the only one here, but he didn't expect Rukia to follow him in. Fortunately, Ichigo Kurosaki didn't follow, otherwise things would have become even more troublesome.

Lin Yu sighed helplessly, then drew out his Zanpakuto, seemingly having made a decision. Rukia was startled when she saw Lin Yu draw out his sword, and she stepped back repeatedly. Her face was filled with fear, and she didn't understand why Lin Yu did this.

"Teacher? What are you going to do?" Rukia asked in a trembling voice, fear flashing in her eyes. She couldn't believe that her teacher would draw a sword against her, and her heart was filled with fear.

Lin Yu didn't answer Rukia's question, but instead gently placed the knife on her body. His movements were gentle and soft, as if he was afraid of hurting Rukia. As he moved, a star power emanated from the knife, enveloping Rukia's body.

"Protection from the stars!" Lin Yu whispered softly. As he spoke, Rukia felt a surge of warm spiritual pressure flow into her body, instantly dispelling the miasma that had engulfed her. At the same time, her spiritual pressure began to gradually recover, even becoming stronger than at its peak. Rukia felt the spiritual pressure filling her body and looked at Lin Yu in surprise.

"Teacher...what is this?" Looking at everything happening in front of her, Rukia asked with a puzzled look.

Lin Yu smiled slightly, put away the knife in his hand, gently stroked Rukia's head and said: "Have you forgotten? This is the power of my Zanpakuto. I used it on you before."

Rukia blinked and muttered to herself, "Isn't it said that the power of the stars can only restore spiritual pressure? How can it also increase spiritual pressure?" But at this moment she realized that there was something more important that needed to be figured out.

She asked anxiously, "Teacher! Didn't the Soul Society's high-ranking officials say that you had betrayed the Soul Society and were killed by Captain Aizen? But why are you still alive? Did you really betray the Soul Society?"

Lin Yu raised the corners of his mouth slightly, revealing an unfathomable smile, and then replied softly: "Guess!"

"Teacher, please stop joking." Rukia's expression became increasingly anxious. "What exactly happened back then? Please tell me!"

Lin Yu restrained his smile and his expression became serious. He looked into Rukia's eyes and said in a deep voice: "Rukia, there are some things I can't tell you now. But you must believe that I will never betray the Soul Society. As for why I didn't die, you will naturally know in the future."

With that, he turned and walked away, leaving Rukia lost in thought. She was filled with questions, yet also felt a sense of relief. At least her teacher was still alive. Rukia decided to put aside her doubts for the time being, believing that her teacher must have his own difficulties.

"Wait for me! Teacher." Rukia looked at Lin Yu walking forward and shouted hurriedly, while quickly following him.

Lin Yu looked back at Rukia and shook his head helplessly: "Rukia, you shouldn't have followed me into the Gate of Hell. The existence in here is not something you can deal with now."

Rukia scratched her head awkwardly. "I just followed in on impulse. I didn't expect it to be so dangerous..."

Lin Yu was speechless for a moment, thinking that this child was really impulsive. But since he had already come in, he could only face it together.

As they continued forward, the atmosphere around them grew increasingly eerie and oppressive. Suddenly, a low roar came from the front. Rukia nervously gripped her Zanpakutō, ready to respond to any possible danger.

Those roars were all roars from the souls on the white squares. They were unwilling to sink in hell and wanted to escape from this world.

Lin Yu calmly observed his surroundings, secretly alert in his heart. He knew that in hell, any negligence could lead to fatal consequences.

At this moment, a huge hell watcher appeared, grabbed the screaming souls and swallowed them.

After swallowing the roaring soul, the Hell Guardian set his sights on Lin Yu and Rukia, roaring and rushing towards them.

Rukia trembled while holding her Zanpakuto. The pressure emitted by the Guardian of Hell made her extremely uncomfortable.

Seeing this, Lin Yu flashed and instantly appeared in front of the Hell Guardian. With one blow, he chopped it into a magma state and waited for resurrection.

"Rukia, follow me closely, otherwise it will not be fun to die in hell." Lin Yu said with a relaxed look on his face, the Zanpakuto in his hand exuding a sharp aura.

Rukia gripped the hilt of her knife tightly and asked nervously, "Teacher, what are these monsters?"

Lin Yu raised the corners of his mouth slightly and explained, "This is the guardian of hell, who specializes in devouring the souls of those who have committed heinous crimes. However, all creatures in hell will be reborn after death, but the length of time it takes to be reborn is different."

As she spoke, another guard roared and rushed over. Rukia calmed herself and drew her sword. However, the Zanpakutō made a sound of metal hitting metal when it hit the guard's body, causing no damage.

Rukia's eyes widened in shock, staring at the guard in disbelief. At that moment, Lin Yu quickly stepped forward and easily killed the guard with a single swing of his sword. The guard's body instantly transformed into boiling lava, flowing to the ground.

Lucia gasped, looking at the scene in front of her with astonishment. She once again realized the huge gap in strength between herself and Lin Yu, and a strong sense of disappointment surged in her heart.

Lin Yu walked to Rukia with a smile and patted her shoulder gently: "Don't be discouraged, Rukia. As long as you keep working hard and practicing, one day you will be as strong as me." His comfort was like a fart. It was foolish to think that you could become so strong as long as you worked hard!

Rukia took a deep breath, an inexplicable light flashing in her eyes, and nodded in response: "I will definitely work hard, teacher!"
