This kind of change was difficult to put into words, but he could clearly sense that through the constraints and tempering of Conan's world, his power seemed to have become purer and more resilient.
Although this change was subtle, it brought him an unprecedented sense of comfort and ease, as if both his body and soul had undergone some kind of sublimation during this journey.
This change was undoubtedly a good thing; it meant that through traveling and training in different worlds, he was gradually growing into a more powerful existence.
Roy was already looking forward to it.
He looked forward to continuing to explore more unknown worlds in the days to come, experiencing different kinds of power, and allowing himself to grow continuously in this endless universe.
Time passed quickly, and Uchiha Sasuke had already returned to Konoha Village with Team 7.
During this period, Uchiha Sasuke had been working diligently and striving to improve; Naruto's immense strength had stimulated him, deeply stinging his heart and igniting a deep desire for power within him.
Thus, Sasuke began a journey of nearly harsh self-training.
He not only practiced various ninjutsu diligently day by day, but also delved into the Marine Rokushiki.
Kakashi had been silently observing Sasuke's changes from the sidelines.
Kakashi was curious about how Sasuke had come into contact with this unique set of combat skills, but upon second thought, since it was greatly beneficial to Sasuke's growth, he didn't interfere too much.
Moreover, even he couldn't help but want to experience the Marine Rokushiki himself.
Kakashi pondered to himself, his fingers gently brushing over his iconic Sharingan.
As the Copy Ninja, he possessed the ability to copy and learn others' ninjutsu, and the Sharingan was key to this ability.
However, the reason he could become the one and only Copy Ninja, besides the assistance of the Sharingan, was more importantly his understanding and flexible application of ninjutsu.
Whenever Sasuke practiced the Marine Rokushiki in front of him, Kakashi would use his keen insight to meticulously record Sasuke's every movement and every breath.
Although he wasn't familiar with the specific secrets of the Marine Rokushiki, relying on his rich combat experience and exceptional learning ability, he had gradually figured out some of the basic essentials.

[Notification: Kamado Tanjiro has joined the group chat.]
On this ordinary day, the usually calm group chat suddenly stirred.
This group chat, which had been silent for a long time without new blood, had actually gained a new member!
As soon as this news came out, it instantly shattered the tranquility within the group.
In an instant, many members surfaced one after another and began to speak.
[Hey, a newcomer has arrived. Let's hold a welcome ceremony.] – Tony Stark.
[Another kid?] – That was Fushiguro Megumi.
At this moment, Kamado Tanjiro, the center of this lively discussion, was utterly bewildered.
He had no idea why he had been inexplicably pulled into such a strange chat group.
He had been fully focused on training diligently under his master Urokodaki, earnestly learning the mysterious Water Breathing sword techniques, and training hard day and night, striving to continuously improve his strength and achieve his goals as soon as possible.
However, this sudden turn of events made him temporarily put down his practice, staring with bewilderment at the constant stream of message notifications in his mind.
Tanjiro stood in a corner of the hut, frowning slightly, his heart filled with confusion.
He felt lost and helpless about this sudden chat group, but soon the members within the group, especially a helpful member named Tony Stark, quickly answered many of his questions.
[This person seems a bit arrogant and talkative.]
Although Tanjiro thought this, he soon gradually understood that this chat group gathered people from different worlds, with different abilities.
Such a world left Tanjiro in awe; he had never imagined that beyond his own world, there existed such vast and boundless realms.
In Tony Stark's introduction, Tanjiro also learned an important piece of information – there was a universally recognized big shot in the group, and everyone called him Mr. Kizaru.
It was said that this Mr. Kizaru was not only exceptionally powerful but also willing to help, always lending a hand at critical moments to assist group members in solving various problems.
Tanjiro couldn't help but feel a sense of respect, while also quietly wondering to himself, "I wonder, compared to my teacher, who is stronger, Mr. Kizaru?"
In his mind, he pictured the figure of his teacher Sakonji Urokodaki, the mentor who taught him Water Breathing and guided him onto the path of the Demon Slayer Corps. What would it be like compared to this big shot?
Meanwhile, Roy was sitting somewhere in the world of One Piece, quietly observing the addition of the new member, Tanjiro.
Watching the group chat regain vitality due to the new member's arrival, Roy felt a sense of satisfaction.
"It seems this chat group is still continuously growing and expanding," Roy murmured to himself.
While occasionally popping up in the group chat, Roy was simultaneously engaged in an activity that seemed out of place in the Marine Headquarters' conference room – goofing off.
Yes, he was currently in the Marine Headquarters' conference room, but he was goofing off.
Inside the conference room, the atmosphere was heavy and tense.
Fleet Admiral Sengoku stood at the podium, his voice loud and clear as he spoke about the severe situation of the current Great Age of Pirates.
Below, the Vice Admirals of Marine Headquarters sat in neat rows, their expressions focused and their gazes firm.
However, amidst this solemn occasion, the behavior of a few heavyweight figures was completely out of sync with the atmosphere.
Akainu remained silent, his signature stern expression completely hidden beneath the low brim of his cap, making it impossible to glimpse his true thoughts.
Aokiji appeared drowsy, seemingly uninterested in the meeting's content.
As for Roy, he took goofing off to the extreme. Although his body was in the conference room, his mind had long since wandered to the chat group.
He only occasionally looked up at Fleet Admiral Sengoku's speech, listened symbolically for a few sentences, and then quickly dove back into the chat.
"Now, the situation is very severe. This Great Age of Pirates has exceeded expectations; it must be curbed."
Fleet Admiral Sengoku shouted again, trying to capture everyone's attention.
His words were filled with anger towards the rampant state of pirates on the islands.
However, when his gaze swept downwards, he found that while the Vice Admirals were spirited, the performance of the three Admirals left him feeling helpless.
Akainu's silence, Aokiji's drowsiness, and Roy's goofing off all left him exasperated.
Then, he looked at Garp, who was constantly snoring off to the side.
For a moment, he felt that this place was beyond hope.
