Death: Captain Millennium

Soul Society has been quiet for a long time, but recently something major has occurred – a captain's meeting has stirred up a new wave. It turns out that Ginjo Kūgo, the first Shinigami agent recognized by Soul Society, suddenly lost contact with Soul Society a few days ago and is now missing.

Captain Yamamoto took this matter very seriously and immediately ordered Ukitake Jushiro of the 13th Division to conduct a thorough investigation. After all, it was Ukitake who had originally proposed and established the Shinigami proxy system, so it was only natural that he would be the one to handle this matter.

Upon receiving the order, Ukitake immediately began his investigation. First, he began searching for clues at Ginjo Kūgo's last known location. According to the Technology Development Bureau's report, Ginjo was last seen in Karakura Town, where he vanished without a trace.

Ukitake speculated that Ginjō might have encountered an enemy too powerful for him to deal with, or was trapped in a predicament from which he was unable to struggle.

Later news came that Ginjo Kugo had not disappeared, but had defected, the exact reason for which remains unclear. His defection was confirmed because Ginjo Kugo attacked the 13th Division's Shinigami, who were searching for him.

After receiving this news, Ukitake plans to go to the human world in person to find out the truth.

However, at this moment, Lin Yu came to the door.

"It's Captain Lin Yu. Why did you think of our 13th Division?" Fuzhu said and coughed lightly a few times.

Lin Yu looked at Fuzhu's physical condition and asked with concern: "Fuzhu, your health is getting worse and worse. Is it because of that reason?"

"Yes!" Ukitake nodded helplessly.

"Then let me go to the mortal world to handle this incident. It happens that Bayunzhai and I haven't seen each other for a long time, and I miss her very much." Lin Yu volunteered.

Fuzhu asked with a half-smile, "Lin Yu, are you interested in this as well?"

Hearing this, Lin Yu quickly waved his hands and said, "No, no, no, I'm not interested in this matter. I just want to take over Yunzhai."

Fuzhu, who saw through Lin Yu's intention, said nothing. "If you want to go, you have to ask the captain for permission. I don't have the final say."

"That's easy!" After saying that, Lin Yu pulled Fuzhu and went to the first team's barracks.

After arriving at the First Squadron barracks, Lin Yu pulled Ukitake and walked in front of Yamamoto Genryūsai Shigekuni.

"Captain, you see Fuzhu hasn't been in good health lately." Lin Yu patted Fuzhu's back in what he considered to be a secret.

Fuzhu received the hint and immediately started acting with Lin Yu.

"cough cough"

Another cough came from Fuzhu's mouth.

The captain watched Lin Yu perform quietly and asked, "Tell me, what's the matter?"

Lin Yu said with a smile: "Captain, I haven't seen Bayunsai for a long time. The place where Ginjo Kugo last disappeared was in Karakura Town, and Bayunsai was also there, so I hope you can approve me to go on this mission."

Captain Yamamoto considered the situation for a moment, then said, "Okay, I approve your replacement for Ukitake on this mission."

Hearing this, Lin Yu was delighted and quickly said, "Thank you very much, Captain." A happy smile spread across his face.

However, at this moment, the captain suddenly said again: "Wait a minute!"

Lin Yu scratched his head in confusion and asked, "Captain, is there anything else you want to tell me?"

The captain looked at Lin Yu with a serious expression and said slowly: "Before going to the human world, you should go to the 12th Division to limit your spiritual pressure. The human world is not like Hueco Mundo. If someone of your level goes there, it will cause irreversible damage to the souls in the human world."

Lin Yu nodded, showing his understanding, and replied, "I understand. It's just a limit of 80% of the spiritual pressure. I'll go find Kurotsuchi Mayuri."

The captain shook his head and corrected him, "No, you have to limit your spiritual pressure by 90% when you go to the human world."

Lin Yu widened his eyes and asked in surprise: "90%, Captain, aren't you afraid that I will be in danger in the real world?"

The captain said with a smile: "Are you in danger? Just don't create danger." After that, he turned and left the room.

Lin Yu sighed helplessly, but could only accept the decision. He knew the captain had a reason for doing this. After all, the real world was different from Hueco Mundo. If his spiritual pressure was too high, it could cause great damage and impact on the real world. Therefore, he could only follow the captain's request and go to the 12th Division to ask Kurotsuchi Mayuri for help in limiting his spiritual pressure.

Squad 12 Technical Development Bureau

"Captain Lin Yu, do you have something to talk to me about?" Kurotsuchi Mayuri stopped the experiment in his hands and looked at Lin Yu who walked into the laboratory with confusion.

"Captain Mayuri Kurotsuchi, I have to go to the human world to carry out a mission. The captain asked me to limit the spiritual pressure." Lin Yu explained.

"Is that so? Yin Meng! Come here and limit the spiritual pressure for Captain Lin Yu." Kurotsuchi Mayuri ordered.

A petite female Shinigami approached. She was wearing a white lab coat and looked very quiet. How should I put it? She looked like a medieval maid. I hadn't expected Mayuri Kurotsuchi to have such a hobby.

Lin Yu looked at the female Death God in front of him with curiosity. He then turned to Kurotsuchi Mayuri and asked, "Is this the artificial Death God that Captain Kurotsuchi Mayuri created by combining the Artificial Corpse and Artificial Soul technology?"

"Oh my! Captain Lin Yu also knows this technology? This is the second generation of artificial death god I created. The first generation was called Mian No. 5, and this one is Mian No. 7, but I gave her a name called Nie Yin Meng." Kurotsuchi Mayuri looked at Lin Yu in surprise.

"Well, I have discussed this technology with Hikifune Kiryu before." Lin Yu nodded.

Kurotsuchi Mayuri was surprised after hearing this. He turned his head and looked at Lin Yu twice, revealing a look of surprise: "I didn't expect Captain Lin Yu to be a scientist too."

At this time, Nie Yinmeng took out a spiritual seal with the emblem of the Seventh Division and began to limit Lin Yu's spiritual pressure.

"Wait a minute!" Lin Yu interrupted Nie Yinmeng's actions.

"Captain Lin Yu, is there anything else?"

"The captain has ordered that my Reiatsu must be limited to 90% when I go into the present world."

Nie Yinmeng was surprised, "90%?"

But I did it anyway.

As Lin Yu slowly injected spiritual pressure into the spiritual seal, he could clearly feel the spiritual pressure in his body gradually decreasing.

"Vice-Captain Yin Meng, is the speed of limiting spiritual pressure always so slow?" Lin Yu had just finished saying this when the spiritual seal used to limit spiritual pressure exploded.

Faced with such a scene, Lin Yu instantly raised his hand to set up a barrier, completely suppressing the shock wave generated by the explosion. Fortunately, he reacted quickly, otherwise, with this force, its power would be equivalent to the self-detonation of a captain-level strongman.

Mayuri Kurotsuchi was so frightened by this sudden change that he jumped up: "Nemue, what on earth is going on?"

Nie Yinmeng looked bewildered: "Captain, I don't know either. The spiritual seal was just absorbing Captain Lin Yu's spiritual pressure normally, and suddenly it exploded."

Lin Yu looked at the spiritual seal that had turned to ashes and frowned. "Captain Kurotsuchi Mayuri, this spiritual seal of yours must be a fake! Otherwise, how could it explode so easily? Fortunately, I reacted quickly, otherwise the consequences would be disastrous."

"Yin Meng, bring over another spiritual seal and limit the spiritual pressure again."

Having learned from his previous experience, Lin Yu didn't remove the barrier, but instead slowly injected spiritual pressure into the seal. As expected, the seal exploded. "Captain Nie, I told you this thing was a rip-off. Look, it exploded again."

Kurotsuchi Mayuri took out another spiritual seal from somewhere and tried to limit his own spiritual pressure. The result was very smooth and the spiritual pressure was successfully limited.

Kuroda Mayuri looked at Lin Yu solemnly, "Captain Lin Yu, do you mind if I draw some blood from you?"

Hearing this request, Lin Yu retracted his hand, "What are you going to do? Since you have set your sights on me, you must be crazy about studying me, right?"

Kurotsuchi Mayuri smiled awkwardly. He was indeed curious about Lin Yu and wanted to study him, but more importantly, he was concerned with the issue of limiting his spiritual pressure. "No, how could I? As Captain Lin Yu just saw, the spiritual seal successfully limited my spiritual pressure. I only wanted to sample your blood to analyze your total spiritual pressure. The spiritual seal exploded purely because its storage limit was too low."

When Lin Yu heard this, his brows furrowed slightly, and a hint of doubt flashed in his eyes, but he still stretched out his hand half-believingly, "Okay, I'll believe you this time, but if I find out that Captain Kuroda Mayuri is using my blood for other research, I will kill you." His voice carried a hint of warning that could not be ignored.

Kurotsuchi Mayuri looked at Lin Yu's outstretched hand, a sly smile on his face. He knew in his heart that the seemingly young captain of Division 7 wasn't so easy to fool. But as a great scientist, he had enough confidence to handle any situation. He smiled and said, "Don't worry, Captain Lin Yu, I just want to get some useful information from your blood. I won't do anything else excessive. After all, we are all members of the Gotei 13 and should trust each other."

Lin Yu listened to Kurotsuchi Mayuri's words and nodded slightly in agreement. He knew that despite his eccentric personality, Kurotsuchi Mayuri was a master in scientific research. Furthermore, he trusted Kurotsuchi Mayuri wouldn't do anything to harm him. So, he extended his hand to Kurotsuchi Mayuri, ready to let him take his blood sample.

Seeing this, Kurotsuchi Mayuri immediately took out a syringe and carefully drew a small tube of Lin Yu's blood. He placed the syringe in a specially made container and sealed it. Then, he nodded to Lin Yu and said, "Alright, Captain Lin Yu, thank you for your cooperation. I will complete the analysis as soon as possible and let you know the results."

Lin Yu looked at the blood sample in Kurotsuchi Mayuri's hand, feeling somewhat uneasy. He didn't know what secrets Kurotsuchi Mayuri could uncover from his blood. But he also understood that since he had already promised Kurotsuchi Mayuri, he could only wait for the results. He took a deep breath, calmed himself, and then said, "Okay, Captain Kurotsuchi Mayuri, I hope you can keep your promise. If I discover any misconduct on your part, you will bear the consequences yourself."

At Lin Yu's warning, Kurotsuchi Mayuri's lips curled up slightly, revealing a subtle smile. He knew Lin Yu was not someone to be trifled with. If he caught him doing anything wrong, he would definitely find trouble with him. However, as a great scientist, he possessed a strong curiosity and thirst for knowledge, always eager to explore the unknown. So, even in the face of Lin Yu's threats, he showed no sign of backing down.

"Don't worry, Captain Lin Yu, I will definitely give you a satisfactory answer," Kurotsuchi Mayuri said confidently. He then turned and walked into the lab, beginning to analyze Lin Yu's blood sample. Lin Yu stood there, watching Kurotsuchi Mayuri's retreating figure, silently praying that he wouldn't do anything dangerous.

In the laboratory, Kurotsuchi Mayuri was using sophisticated instruments to analyze Lin Yu's blood. After a while, he roughly estimated the total spiritual pressure of Lin Yu.

"Hiss!" Kurotsuchi Mayuri gasped and exclaimed, "What kind of horrible monster is this?"

Based on past experience, the spiritual pressure strength of captain-level personnel is usually divided into three grades to one. However, the initial results obtained by Kurotsuchi Mayuri left him dumbfounded - Lin Yu's spiritual pressure had actually exceeded the scope of the first grade, and as for the specific grade, even Kurotsuchi Mayuri himself was unable to determine.

Despite this, Mayuri Kurotsuchi was still able to create a limited-edition Spiritual Seal based on his estimated Reiatsu. After all, he was the Director of the Technology Development Bureau, so he had some ability.

Mayuri Kurotsuchi sighed inwardly, "No wonder Captain Yamamoto wanted him to limit his Reiatsu to 90%. Otherwise, he'd be a walking killing machine if he showed up in the real world. He wouldn't have to do anything, just stand still, and everyone around him would die in droves, unable to withstand the Reiatsu he exudes. He's truly a true alternative Shinigami." Thinking of this, Mayuri Kurotsuchi couldn't help but feel a touch of awe towards Lin Yu. He walked over to Lin Yu with his newly made Reiatsu seal in hand, a hint of pride in his eyes.

"Captain Lin Yu, try this. It's guaranteed to limit your spiritual pressure."

Lin Yu stretched out his hand and carefully took the spirit seal from Kurotsuchi Mayuri. After taking a deep breath, he slowly injected his own spiritual pressure into it.

This time, the spiritual seal did not explode directly like before, but emitted a faint light, which gradually became brighter as Lin Yu input spiritual pressure.

Seeing that the spiritual seal had finally stabilized, Lin Yu breathed a sigh of relief: "Finally it succeeded..."

He carefully sensed the restricted spiritual pressure within him. While still powerful, after comparison, it was only 10% of its capacity. He nodded with satisfaction and said to Kurotsuchi Mayuri, "Thank you, Captain Kurotsuchi Mayuri. Now, I can return to the human world without worry."

Kurotsuchi Mayuri smiled and nodded, explaining, "Captain Lin Yu, your spiritual pressure is truly too strong. I had to make some special designs to accommodate it. This spiritual seal may be a little unstable, but it should be sufficient in the real world."

Lin Yu patted Kurotsuchi Mayuri's shoulder gratefully, expressing his understanding and gratitude. "Thank you for your hard work, Captain Kurotsuchi Mayuri. I will use it carefully and will not cause you any trouble."

After saying that, Lin Yu turned and left the laboratory, carrying his body with limited spiritual pressure, and went to the real world to find the whereabouts of Ginjo Kūgo.
