One Piece: Kaido's adopted son, starts with the Eight Gates Formation.

the next day.

Lynn was awakened by the smell of roasted meat.

He sat up on the small bed that Kaido had specially made for him, his hair a mess like a bird's nest. He first grabbed a piece of meat and stuffed it into his mouth, his eyes not even fully open yet.

Kaido had been squatting nearby waiting for quite some time.

"Young Master, shall we go to the Shadow Realm?"

"Wait until I finish eating."

Lynn gave a vague reply.

Just then, a familiar system notification suddenly rang in my mind.

[Ding! Detected that the host is about to complete a phase of the Bleach world walkthrough.]

[Capability source calibration is underway.]

Lynn paused in his chewing motion.

A semi-transparent panel unfolds before your eyes.

[Permanent Abilities: Top-tier Conqueror's Haki, Flying Technique, Eight Gates, Amaterasu, Perfect Susanoo, Special Beam Cannon, Ultra Instinct, Healing, Kaioken, True Several Thousand Hands - Top Transformation Buddha, Instant Transmission, Super Saiyan Bloodline.]

[Permanent Item Slots: Time Wrapper, House of Time and Spirit.]

[Existing enhancements: Constitution, Stamina, Conqueror's Haki cap, as well as completed skill cost reductions and power enhancements, are all retained.]

Below that is another column, which the system has deliberately highlighted in dark red.

[Current World Temporary Rule Authority: Absolute Now, Omniscient and Omnipotent Eye, etc.]

[Note: This type of ability originates from the core rules, special medium, or phased resonance of the Bleach world and is only maintained in the current world; it is automatically sealed after leaving this world, does not enter the permanent ability slot, and is not used as a basis for combat power in subsequent worlds.]

Lynn stared at it for a few seconds.

"oh."

That's it?

He thought the system was going to give him something new again.

Kaido leaned closer: "What's wrong?"

"It's alright." Lynn took another bite of meat. "The system said that those strange abilities found in this world can't be taken with you."

"If you can't take it, you can't take it." Kaido didn't care at all. "Weren't your previous tricks ruthless enough?"

"I think so too."

Lynn nodded.

To be honest, he actually prefers the Eight Gates, Susanoo, and Kaioken – techniques he's used all the time.

I know how it came about.

I know how to use it.

It's exhilarating to fight like that.

As for concepts, rules, present, future... it's fine to play around with it occasionally, but if every world has to rely on these things to get through in the future, what's the point?

"I won't use these temporary measures when playing Yhwach today."

Lynn stuffed the last bite of meat into his mouth and jumped out of bed.

"Let's see if he can handle what I used to have."

Kenpachi Zaraki, who was dozing off by the door, immediately opened his eyes upon hearing the word "hit".

"Have you set off?"

"Um."

Aizen walked in at that moment.

"The location of the entrance has changed."

He spoke calmly.

"Yhwach did indeed take action last night. He didn't flee; instead, he gathered all the remaining Quincy from the Shadowlands towards Silverframe Castle."

"Where is the Spirit King's left arm?" Lynn asked.

"There too."

Aizen paused, then smiled slightly. "It seems he knew we were going today."

Lynn blinked.

"That's perfect."

Saves me the trouble of looking.

Half an hour later.

The edge of the God-Slaying Island was crowded with people.

Kaido, Whitebeard, Shanks, Mihawk, Akainu, Kenpachi Zaraki, Aizen... they were all getting impatient.

Kyoraku's lips twitched as he looked at the lineup.

"Are you going to get an arm, or are you preparing for another world-ending war?"

Kaido picked up his spiked club.

Is there a difference?

Kyoraku was speechless.

Lynn floated to the front, and raised her chin at Lanzan.

"Open the door."

Aizen reached out his hand.

The shadows spread silently beneath everyone's feet.

A pitch-black portal leading to the realm of shadows slowly opened.
