Death: Captain Millennium

Lin Yu bid farewell to Nel and continued his journey through Hueco Mundo alone. Since arriving in Hueco Mundo from Soul Society, Lin Yu's goal has remained the same: to learn Bankai and become a more powerful Shinigami. After so long in Hueco Mundo, Lin Yu's Zanken Zougui skills have improved significantly, but the secrets of Bankai remain elusive.

"Thunder Emperor", Lin Yu called out the name of his Zanpakuto and came to the world of Zanpakuto again.

"I'm here, I want to learn Bankai." Lin Yu was too lazy to talk nonsense.

"Here you go again. You say this every time you come to see me. You are so persistent. Bankai is not something you can learn just by saying it. You don't understand the meaning of Bankai at all. Go back. When you understand what I said one day, come to me again. I don't want to see you for the time being." With a wave of his hand, the Thunder Emperor forced Lin Yu back to the real world.

Lin Yu stood there bewildered, his mind filled with doubt and confusion. He didn't know what he had done wrong. Why did Thunder Emperor always refuse to teach him Bankai? Was it really because he hadn't grasped the true meaning of Bankai? But what exactly was Bankai? Lin Yu fell into deep thought. He decided to put aside the idea of ​​learning Bankai and focus instead on cultivating his mind.

"It seems I won't be able to learn Bankai from the Thunder Emperor anytime soon. I'll have to rely on my own understanding. Better leave Hueco Mundo and return to Soul Society." Lin Yu opened his eyes and sighed helplessly. He had originally thought he could learn Bankai from the Thunder Emperor, but now it seemed that this goal was unattainable in the short term. He decided to rely on his own efforts to comprehend the secrets of Bankai.

Lin Yu stood up, preparing to leave Hueco Mundo. He pondered, "What exactly is the meaning of Bankai? Isn't it simply a boost in strength, but rather a breakthrough in state of mind? Perhaps only when I truly understand the essence of Bankai can I master its power." He knew that Bankai wasn't just a skill or ability, but rather a spiritual elevation.

Lin Yu drew his Zanpakutō and opened the gate to Soul Society. As he entered, he was greeted by a bizarre scene: the Dangai. The time here was 2000 times the time of the outside world, meaning that two thousand years of cultivation here equated to only two years in the outside world. Lin Yu couldn't help but exclaim, "This place is truly bizarre!"

However, Lin Yu also realized that Dangai was not a safe place. Encountering a Kuto would be extremely dangerous. To enter Kuto's interior, one must eliminate their own spiritual pressure, otherwise they would be devoured. Thinking of this, Lin Yu shook his head and thought, "Never mind, this idea is too crazy. I'd better not take this risk." So, he continued on, crossing Dangai and eventually returning to Soul Society, after a long absence.

"You're willing to come back. I thought you died in Hueco Mundo." As soon as Lin Yu came back, Bayunzhai sensed his spiritual pressure and quickly rushed over from the captain's office.

Before Bayunzhai could vent her anger, Lin Yu hugged her in his arms, "Ah, ah, ah! I'm back. I made you worry."

"You've been away for so many years, and you want to get rid of me with just one sentence." Bayunzhai was like a punching bag. "Actually, I heard everything you said when you were drunk last time. I was pretending to be drunk on purpose."

Lin Yu ruffled Bayunzhai's hair and said, "The captain turned out to be a big liar. All right! Go prepare the ingredients for the hot pot. I'm going to report to the captain of the First Division first. I've been in that godforsaken place of Hueco Mundo for so long, I'm really greedy."

"Well, go quickly and come back early." At this moment, Bayunzhai was like a well-behaved young wife who was seeing her husband off.

"I don't know how many years have passed. In that damn place of Hueco Mundo, there is no distinction between day and night. I should have asked Bayunzhai just now." Lin Yu thought as he hurried on his way.

"Stop! This is the first squadron's key area."

Lin Yu, who was thinking with his head down, was stopped by someone. He looked up and saw that the person in front of him was wearing a Death God costume that was different from most Death Gods. His Death God costume was white and black, with silver-white hair and golden eyes. What a handsome guy.

Wait...isn't this the tragic guy who was killed by the plot?

Chojiro Suzuki.

It seems I've been in Hueco Mundo a bit too long; even he's already here. "I'm Lin Yu, Vice Captain of Division 8. I need to speak to Captain-in-Chief Yamamoto." Lin Yu suppressed a smile and stated his purpose.

"Vice-captain of the 8th Division? I've never heard of Captain Bayunsai promoting a vice-captain." Chojiro thought for a moment. "Wait a moment, I'll report to the captain-in-chief."

Alas! Chojiro Suzuki's presence here only proves he's already mastered Bankai, and the Captain-General has accepted him. I've been in Hueco Mundo for so long, and I still can't use Bankai. It's truly shameful. Am I still a genius? Or perhaps I was born a fool?

"Sorry for the long wait, Vice Captain Lin Yu. The captain is in the courtyard. Please follow me." Chojiro brought Lin Yu into the First Division with doubts. When he met the captain just now, he said that there was a guy who claimed to be the vice captain of the Eighth Division who wanted to see him. The captain directly asked him to come and pick this guy up to meet him, and they didn't have to go to the reception room. Chojiro really couldn't figure it out no matter how hard he tried.

"Captain, Vice Captain Lin Yu is here. I'll take my leave now."

"Chojiro, stay here. I introduced you to each other just now." The captain stopped Suzube who was about to leave.

"Hey! Captain, it's been a long time since we last met. What's wrong with the wound on your forehead?" Lin Yu asked knowingly.

"You're talking about this. This is what the brat in front of you left for me. Now I've changed my name to Yamamoto Genryūsai Shigekuni."

"How could I possibly deserve this honor? The captain thinks too highly of me."

Ignoring what Chojiro said, the captain continued, "Let me formally introduce you. This brat's name is Chojiro Suzuki, and he's my vice-captain now. His Zanpakutō is a lightning-type like yours, but it's the Yanlingmaru, known as the strongest lightning-type."

"Is the thunder type the strongest?" Lin Yu really wanted to see it and was eager to try it.

"Choujiro, do you want to spar with Lin Yu?"

"Since the captain has spoken, I will fight with Vice Captain Lin Yu." In fact, after hearing that the Zanpakutō of the man in front of him was also of the lightning type, Chojiro could no longer hold back.

First Team Training Ground...

Lin Yu and Chojiro set up their positions. "Vice Captain Sparrow, please."

Chojiro didn't act pretentiously and said, "Go through him, Yanlingmaru." He raised his hand, released his Zanpakuto, and slashed at Lin Yu.

Lin Yu dodged instantly, drew out his Zanpakuto and fought back, and the two sides fought back and forth.

After several rounds of fighting, Chojiro began to feel the strain. "Is he really just a vice-captain? He can fight me on equal terms without unleashing his Zanpakutō, holding his own. It seems I'll have to use my Bankai to suppress him. After all, Yanlingmaru is the strongest lightning-type Zanpakutō. Even if he unleashes his Bankai, I can still suppress him with my Zanpakutō." After another exchange of blows, Chojiro distanced himself. "Vice-Captain Lin Yu, I'm about to unleash my Bankai. Please do the same. Otherwise, you'll get hurt."

"Bankai, Huanghuang Yanlingli Palace." The spiritual pressure from Chojiro's Zanpakutō was instantly released into the air, causing the electrons in the air to condense into a huge spiritual pressure. The entire Seireitei was instantly covered with dark clouds and an oval-shaped electric light appeared. The light split into eleven rays and surrounded him.

"Gaiyi Tianxiang, it is worthy of being the strongest Zanpakutō of the lightning type. The oppressive feeling is really strong. It seems that I can't block this move without releasing it. Then let me try the level of this strongest Zanpakutō of the lightning type." Facing Chojiro's Bankai, Lin Yu also became serious.

"Under the starry sky, thunder shakes the nine heavens. The divine thunder of the sky slays gods and destroys demons. Release it, Thunder Emperor Sword!" Lin Yu released his Zanpakuto, and the spiritual pressure around him soared at once.

"How is it possible? He has reached this level just by his Shikai. Even if this man's strength cannot compare to the captain-general, it won't be too far behind. As expected, the level of strength does not depend on the Zanpakutō in one's hand. Even if one has the strongest lightning-type, it is useless." Chojiro gathered 11 lightning bolts onto the blade and lunged forward.

Lin Yu raised the Thunder Emperor Sword high, and with the Thunder God's judgment, a divine thunder from heaven was drawn down from the sky by Lin Yu. With a wave of the Zanpakuto in his hand, the divine thunder struck Chojiro who was rushing towards him.

"boom"

The lightning flashed so brightly from the collision that people couldn't open their eyes. Chojiro also flew backwards, his Death Tyrant suit in tatters, obviously injured by Lin Yu's move.

"Are you okay, deputy captain of the Sparrow Department?" Lin Yu sheathed his knife and prepared to check his injuries.

"Hehe! No problem, Vice Captain Lin Yu, just call me Chojiro." Chojiro was convinced. Lin Yu defeated him without even using his Bankai. His strength was truly terrifying.

"I also want to thank Vice Captain Lin Yu for holding back and not using Bankai. I wonder if I could see your Bankai." Looking at Lin Yu's wry smile, Chojiro thought he was being presumptuous. It was irrational to force a powerful being to use Bankai.

"Choujiro, um..."

"Actually, I don't know Bankai yet," Lin Yu said ashamedly, holding his forehead with his hand.

"Huh?" Two surprised voices were heard. Not only Chojiro, but even Captain Yamamoto was surprised. "This kid hasn't even learned Bankai yet. It's really weird."

Chojiro was also confused. He was so strong before he even learned Bankai. What would happen if he learned Bankai?

What a monster!

The battle had just attracted a large number of shinigami to watch, after all, the range of influence of Chojiro's Bankai was too large. "Let's go back to my captain's office first, the crowd is increasing," Captain Yamamoto said, stopping Chojiro before he could continue.

"Lin Yu, you said you haven't learned Bankai yet. That doesn't make sense. Tell me in detail what the reason is. I'll see if I can help you answer it." Captain Yamamoto asked anxiously.

Lin Yu relayed what the Thunder Emperor said to him to the captain, "Strange, since you have already mastered the Shikai, it stands to reason that as long as you keep developing it towards the Thunder Emperor Sword, Bankai will come naturally. You shouldn't be unable to Bankai yet." Captain Yamamoto couldn't find the answer to this situation for a while.

"Choujiro, you may have a lot of doubts. Lin Yu joined the Gotei 13 two hundred years ago. He mastered the Shikai in less than a year. After that, he went to Hueco Mundo to hone his skills in order to learn Bankai. That's why you haven't seen him in Soul Society." Captain Yamamoto told Chojiro something that had always puzzled him.

He joined the Gotei 13 two hundred years ago, learned his Shikai in less than a year, and honed his skills in Hueco Mundo. Even now, he still doesn't know Bankai, yet his strength is ridiculously strong. Chojiro was completely stunned after hearing this. What kind of thing is this? This is a monster.

Captain Yamamoto and Chojiro wanted to continue asking questions, so Lin Yu said goodbye.

"We just returned to Soul Society. Is there anything you need to deal with today?" Captain Yamamoto wanted to keep Lin Yu to continue asking him about Hueco Mundo.

"Captain, I'm fine. It's just that it's getting late and Bayunzhai is waiting for me to go back for dinner, so I won't stay any longer." Lin Yu laughed.

"You little devil..."

"Go back, go back, otherwise you will make Bayunzhai angry." The captain, who was originally a little angry, changed his expression in an instant.

Lin Yu stood up and said goodbye...

Chojiro next to him opened his mouth wide and pointed in the direction Lin Yu left.

"He he he..."

"He actually called Captain Bayunzhai's name directly and said that he was waiting for him to come back for dinner. Captain, did I hear it wrong?" Lin Yu's words made Chojiro feel even more outrageous than the captain's introduction of his deeds just now.

"Chojiro, you don't know this. Lin Yu and Bayunzhai love each other." The captain laughed rarely.

The captain of the Gotei 13, who usually looks vicious, is actually a loving family with her vice-captain. Chojiro felt as if he had been hit hard by a thousand points of damage. Everything that happened today has overturned his three views.

After leaving the First Division, Lin Yu went straight back to the Eighth Division. As soon as he entered, he saw Bayunzhai busy preparing hot pot ingredients. Lin Yu hurried forward to help.

"You're back so soon, didn't the captain invite you to dinner?"

"I did stay, but I told the captain you were waiting for me to eat, so I rushed back."

"If you tell the captain like that, won't he get angry and chop you with a knife?"

"You guessed wrong. The captain was quite unhappy when I wanted to leave, but when I said I wanted to come back for dinner, he expressed his understanding and happily let me come back."

The two chatted while busying themselves.

"Cheers! I haven't had anything this delicious in almost two hundred years."

After dinner, Lin Yu and Bayunzhai sat on the roof of the Eighth Division, snuggling together and enjoying the evening breeze. Lin Yu told her what he had seen and heard in Hueco Mundo, interspersed with a few cheesy love words he had learned before, which made Bayunzhai blush from time to time.

He recalled his experiences in Hueco Mundo and his conversation with the Emperor of Thunder. Although he still couldn't understand the true meaning of Bankai, he firmly believed that as long as he kept working hard, he would be able to comprehend it one day.

Time is running out. Now that Chojiro has joined the Gotei 13, the most crucial plot in Bleach is almost here: a war between Soul Society and the Quincies led by Yhwach. I can't tell the Captain-General directly. Should I tell him I've traveled from another world, that Yhwach will attack Soul Society, and that we should take down the Quincies first? He'd probably think I'm crazy.

Although he knew that Soul Society won the battle between the Shinigami and the Quincies in the end, he did not know what price Soul Society paid. From the known information, Soul Society suffered heavy casualties. After the war, the Gotei 13 were reorganized, and the captain-in-chief changed the name of Genji Academy to Maou Spiritual Arts Academy. A large number of ordinary souls with spiritual powers from Rukongai were recruited, and at the same time, the captains of each division were changed.

What worried him most was that after the war, the captain-in-chief's first-term disciple at the Maou Spiritual Academy, Kyoraku Shunsui, took over the position of captain of the 8th Division. This meant that Bayunsai either died in this battle or retired after the war.

Lin Yu didn't dare to gamble, for he was afraid of losing Bayunzhai. Looking at the moon in the night sky, Lin Yu held Bayunzhai's hand tightly and suddenly said to her, "Bayunzhai, I will protect you."

"What? Lin Yu, you are so weird. I don't need your protection. You should protect yourself..."
