Death: Captain Millennium

Rukia looked at Uncle Hibiki's serious expression and instantly realized that what she heard today was absolutely confidential. She couldn't help but sit up straight and listen carefully to what her uncle was going to say next.

"Rukia, you know which squad I belong to, right?" Kuchiki Hibiki asked solemnly.

Rukia nodded and replied, "I know, uncle, you are the captain of the special forces of the first squadron, which is also the general squadron."

Kuchiki Hibiki continued, "As the captain of the special forces, I usually carry out classified missions, missions that even the criminal army is not qualified to touch. Over the years, I have discovered some interesting things while carrying out missions."

Rukia asked curiously, "Uncle, please speak."

Kuchiki Hibiki suddenly mentioned that Lin Yu went to the Shinō Spiritual Arts Academy to demonstrate the power of his Zanpakutō to Rukia and the others. This surprised Rukia a little, but she still carefully recalled the scene and said, "I remember very clearly that day, Teacher Lin Yu and Captain Aizen of the 5th Division released their Zanpakutō in the large classroom and introduced their abilities. His Zanpakutō was a star-type sword, a sword with auxiliary abilities. He also used this ability to bless me during my training."

After hearing what Rukia said, Xianghe sneered, "Astral system? Master really knows how to make jokes."

"Rukia, actually, Master's Zanpakuto is not a star-type Zanpakuto, but a rule-type Zanpakuto with powerful attack power. All I know now is that his sword can control the power of thunder and the power of stars." Kuchiki Hibiki said solemnly.

Rukia opened her mouth in surprise. She had never expected that Lin Yu's Zanpakuto had such powerful power.

"But why did Mr. Lin Yu hide the true power of his Zanpakuto?" Rukia asked in confusion.

Kuchiki Hibiki was silent for a moment, then slowly said, "This may involve some high-level secrets, and I'm not too sure about the details. However, since Master chose to conceal it, he must have his reasons. Rukia, you must remember not to trust others easily, not even me or your sensei (my master)."

Rukia nodded, but a puzzled look appeared on her face, not knowing why Hibiki said that.

Hibiki looked at Rukia's expression and smiled before explaining, "That's what I call something interesting."

After Xianghe finished speaking, he suddenly recalled a piece of history about Lin Yu.

As the captain of a special unit, Xianghe often went to the Great Spiritual Book Corridor to look up some information. Once, out of curiosity, he looked through the information on Lin Yu and unexpectedly discovered something shocking.

According to the information in the Great Spirit Book Corridor, Lin Yu was appointed captain of the 7th Division over 300 years ago, and his Zanpakutō is indeed of the Star System. This fact puzzled Xianghe because, according to common sense, such a situation is almost impossible.

However, what's even more surprising is that the information in the Great Soul Book Corridor cannot be tampered with at will. Its existence has nothing to do with the will of the Shinigami. Instead, it serves as a tool for compulsorily collecting and recording all events and information from the beginning of Soul Society to the present day. Some even speculate that its operation may be based on the will of the Soul King.

Xianghe realized the seriousness of the problem and suspected that he might have been tricked, leading to a misconception about Lin Yu. He reported the matter to the captain and accompanied him to the Great Spiritual Book Corridor to review the relevant information. Eventually, he discovered that the captain's records were exactly the same as what Xianghe had seen before.

Furthermore, the information of those around Lin Yu has also changed. This includes Xianghe's master's wife, Luqu Bayunsai. According to the information, she died in a battle with the Quincy a thousand years ago. However, in reality, she is not only alive and well, but has remained in the real world, living a peaceful life.

The same situation also happened to Saito Fuuma, the first captain of the Sixth Division. The information also showed that she died in that war, but she is still alive today, and is also in the human world and has not returned to Soul Society.

This kind of thing is so bizarre that almost no one knows their true identities except the older generation and a few people who know them.

When he and the captain-in-chief discovered this shocking fact, they realized the seriousness of the matter and secretly discussed it many times with the captains who knew everything about Lin Yu. Ultimately, everyone reached a consensus and decided to keep the matter to themselves and not mention it to anyone. Because if it were leaked, it would inevitably cause an uproar and bring unforeseen consequences to Soul Society.

Seeing Xianghe's distracted look, Rukia reminded him, "Uncle, what are you thinking about? Why are you suddenly silent?"

Xianghe's recollection was interrupted by Rukia's words. He came back to his senses and said with a smile: "Nothing, I just thought of some things that happened to my master before."

Hibiki patted Rukia's shoulder and said earnestly: "So, Rukia, in this world, many things are not what we see on the surface. We must remain vigilant and not be easily fooled by appearances."

Rukia nodded, still curious as to why Lin Yu-sensei wanted to hide the power of his Zanpakutō.

"Okay, you just need to know about this. Don't tell anyone, including your teammates." Xianghe instructed.

"I understand, uncle," Rukia agreed.

Xianghe stood up and said, "Well, it's getting late. You should go back and rest."

Rukia also stood up, saluted Xianghe, and turned to leave.

Rukia was walking back to her room, still thinking about what Xianghe said. She felt that Xianghe was right. In this world, there are indeed many things that are not as simple as they seem.

She decided to be more cautious in the future and not be as naive as before. At the same time, she also became more curious and suspicious about Teacher Lin Yu's past.

After returning to the room, Rukia lay on the bed, tossing and turning, unable to sleep.

The next morning, Rukia got up early and returned to Squad 13. She wanted to ask Captain Ukitake about Lin Yu, but the answer she got was the same as what Uncle Xianghe had said.

However, Rukia always felt that something was wrong, but she couldn't put her finger on it. She pondered for a long time, but still had no clue. Finally, she decided to put the matter aside and turned to look for Shiba Kaiyan.

Shiba Kaien has always taken good care of her junior. He is gentle and caring towards his wife Shiba, very respectful and considerate to Captain Ukitake, and has a friend-like enthusiasm and elder brother-like care for his subordinates. After she joined the 13th Division, he personally taught her various fighting methods and showed her special care.

When Rukia is with him, she feels that life is full of sunshine and joy, and Shiba Kaiyan is also a senior she trusts.
