In the end, Rowan still failed to stop Nero from singing at the victory banquet.
For the sake of singing, that woman directly activated her Noble Phantasm and pulled everyone inside. Then she brazenly sang several songs.
Rowan had no choice but to admit that some people truly had no talent for singing.
Listening to Nero sing was like listening to fingernails scrape back and forth across a blackboard. That sound, that pitch—it felt as if a thousand tiny knives were spinning around inside your eardrums, and also as if you had been soaked in spring water.
More importantly, half of that spring water was fire, and the other half was ice.
The fire burned you until your heart itched and your whole body felt uncomfortable. The cold froze you until you trembled all over, chilling you to the bone.
It was practically lethal.
At that moment, Rowan somewhat regretted summoning Nero.
It wasn't that Rowan didn't know Nero's singing was awful. After all, the original story had repeatedly reminded people that Nero and Elizabeth's singing was life-threatening.
The problem was, he really hadn't expected them to sing this badly.
Hearing about it a hundred times was not as good as experiencing it once.
Rowan gained a deep, even comprehensive understanding of that saying.
Fortunately, although Rowan failed to stop Nero from singing at the celebration, after his repeated delays, by the time Nero started singing, the victory banquet was already nearing its end.
So everyone's mood was not ruined by Nero's singing, and the banquet did not end unhappily.
Moreover, when Nero used her Noble Phantasm—Aestus Domus Aurea, the Golden Theater that Invites One to Rapture—and wrapped everyone inside, opening her throat in front of the crowd and immersing herself in her own moving song,
Rowan decisively used the Door-Door Fruit and slipped out of the Golden Theater.
So Rowan only heard the beginning of that concert.
Another thing worth mentioning was that when Rowan left, he did not take the others with him. He left them inside the Golden Theater. As a result, when everyone ate breakfast the next day, the gazes they gave Rowan were full of resentment.
They had seen people who lacked loyalty, but never someone this disloyal.
Especially Medea and Medusa.
The way they looked at Rowan was as if they wanted to kill him.
Rowan laughed awkwardly a few times. He didn't even finish breakfast before fleeing in disgrace.
A while later, Tsunade brought Hashirama Senju, Tobirama Senju, Orochimaru, and the others over to find Rowan.
"Open a door. We're planning to go back."
The matter in the One Piece world had already come to a temporary end, and the issue of artificial Devil Fruits was more or less settled as well.
It was time for them to return and save their own world.
Although there were still more than ten years before the Otsutsuki descended upon the ninja world, Isshiki Otsutsuki and Kaguya Otsutsuki were still in the ninja world and needed to be dealt with in advance.
And Black Zetsu was still causing trouble in the ninja world.
If they didn't handle all these messy issues, how could they focus on dealing with the Otsutsuki?
Rowan thought about it and agreed. He opened a door and sent Tsunade and the others back to the Naruto world.
Of course, before going back, Orochimaru had already prepared Illya and Sakura Matou's bodies in advance and transferred the two girls into their new bodies.
The new bodies were the same as their previous ones, perfectly responsive, without any issues.
This made Heracles and Medusa very satisfied.
Rowan was also quite satisfied.
As expected of Orochimaru, who had mastered core technology. When it came to cloning, he was still very authoritative.
Especially after communicating with Vegapunk, Rowan felt that this guy had suddenly opened his mind.
He was becoming more and more impressive.
Rowan believed that in the matter of opposing the Otsutsuki clan, this guy would absolutely play a crucial role.
A few days after the people from the Naruto world left the One Piece world,
Serie also came over.
"I should go back too."
"You're leaving too?"
Serie nodded. "I was never a person of this world to begin with. It's time for me to return. What about you? Do you want to visit my world with me?"
Rowan asked, "I have a question. Is the Hero Himmel dead?"
Serie shook her head. "At least before I left, I hadn't heard news of his death."
As the hero who slew the Demon King, Himmel was very famous in her world. If he had truly died, there was no way she wouldn't know.
Since she had received no news, it meant the hero had not died yet.
Rowan gave an "oh." If the Hero wasn't dead, that meant the plot had not yet begun. Stark, the giant mushroom, and those familiar story characters basically hadn't been born yet.
Rowan's anticipation for that world immediately dropped quite a bit.
"Forget it."
After thinking it over, Rowan declined Serie's invitation.
"Maybe later. When I have time, I'll go visit your world."
Serie did not force him and nodded.
"Fine."
Just like that, Rowan sent Serie away as well.
Now, the only people remaining in the One Piece world were the people from the Fate world.
Rowan found them and asked curiously, "What do you plan to do next? Return to your own world, or stay in this world and travel?"
Sakura Matou said, "I plan to go back to school. I haven't graduated yet."
Medusa was not comfortable letting Sakura return alone, so she planned to go back with Sakura.
Illya wanted to go back and see her younger brother, Shirou Emiya, so she also returned with them.
Heracles naturally stayed by her side.
After that, Rin Tohsaka and Heroic Spirit EMIYA also chose to return.
However, before going back, Rin Tohsaka brought a huge pile of gemstones with her.
All of these gemstones had been looted by Heroic Spirit EMIYA from the Holy Land Mary Geoise, from the treasure vaults of the Celestial Dragons. Every single one was a natural gemstone.
They were perfect for using the Tohsaka family's gem magecraft.
With these gemstones, Rin Tohsaka could finally escape the title of poor young lady.
This made Rin look at Heroic Spirit EMIYA in a new light. She even praised him.
"I didn't expect you to be pretty useful after all."
Heroic Spirit EMIYA: "Getting this young lady to praise someone really isn't easy."
Aside from gemstones, Rowan and the others also found a huge pile of Devil Fruits in the Celestial Dragons' treasure vaults.
Altogether, there were actually more than fifty.
Rowan had to admit that the Celestial Dragons were truly wealthy.
Almost every Celestial Dragon family had three to five Devil Fruits hidden away.
Although the Celestial Dragons did not eat these things, they were indeed collectibles used for showing off.
Although most of them were Zoan types or relatively trashy Devil Fruits,
there were still several rare, treasured Devil Fruits among them.
For example, the Time-Time Fruit.
Anyone who had watched One Piece knew this was the fruit eaten by Kozuki Toki, the wife of Wano's foolish daimyo, Kozuki Oden.
Kozuki Toki's original name was Amatsuki Toki. She was a Paramecia-type Time-Time Fruit user who was born more than eight hundred years ago.
Her parents were from Wano's Amatsuki family, but Amatsuki Toki herself had never set foot in Wano.
For some reason, she wanted to go to Wano in the future, so she kept traveling forward through time until, after jumping eight hundred years ahead, she was saved by Kozuki Oden on an island near Wano. Later, she became Kozuki Oden's wife and changed her surname to Kozuki.
The effect of the Time-Time Fruit was not simple either. It could send the user or designated targets through time and space.
In other words, time travel.
But it was limited to traveling into the future and could not return to the past.
It sounded rather useless.
But Rowan seriously suspected that this was only because Kozuki Toki had not developed the Time-Time Fruit enough.
Since it was the Time-Time Fruit, it was naturally a fruit that manipulated time. Traveling to the future, returning to the past, stopping time, reversing time, and fast-forwarding time—there was no way it could not do these things.
Kozuki Toki could not do them very likely because her development of the Time-Time Fruit was insufficient.
It was similar to Kid, the user of the Magnet-Magnet Fruit.
The Magnet-Magnet Fruit could control magnetism and electricity to manipulate iron and other metal objects. It could also create magnetic fields and magnetize metallic objects.
This fruit was deeply connected to electromagnetic interaction, one of the four fundamental forces of the universe.
If developed well, its destructive power would be beyond doubt.
Destroying heaven and earth would be nothing difficult.
But looking at Kid's development, one could tell this guy had never studied science and did not understand science at all. He had completely wasted the fruit.
So Rowan guessed that Kozuki Toki was the same as Kid. Her development of the Time-Time Fruit was insufficient, and she had wasted such a Devil Fruit for nothing.
If this fruit fell into someone else's hands, its potential would be beyond imagination.
Aside from the Time-Time Fruit, there were a few other powerful fruits in the Celestial Dragons' vaults.
The Copy-Copy Fruit was one of them.
Speaking of this fruit, one had to mention someone named Chameleone.
This guy was also from the One Piece world, but like Golden Lion and Red Count Patrick Redfield, he did not appear in the main One Piece story.
He did not even appear in the movies or games.
Instead, he appeared in a certain stage play in Osaka.
This character was also personally designed by Eiichiro Oda. He was a mysterious lizardman who wore green clothing and a mask to conceal his face.
He was also a former member of the Whitebeard Pirates, nicknamed Chameleon, with a bounty as high as three hundred million berries.
The Devil Fruit he ate was the Copy-Copy Fruit. It could precisely reproduce another person's appearance and steal their combat skills, including Devil Fruit abilities and physical techniques.
Interestingly, however, Rowan did not find the person Chameleone in this world.
But the Copy-Copy Fruit he used truly existed in this world.
And it was inside the Celestial Dragons' treasure vault.
Now, it had fallen into Rowan's hands.
Rowan did not stand on ceremony. He decisively ate this Devil Fruit, mainly because the Copy-Copy Fruit's ability-copying skill made Rowan very envious. If used well, this thing could be useful in many situations.
Naturally, Rowan would not miss it.
Of course, aside from these two fruits, there were also a few Mythical Zoans among the Devil Fruits, but Rowan didn't care that much about them.
Ah…
He had gone off topic.
Back to the main point.
After Rin Tohsaka and Heroic Spirit EMIYA left, the others also returned to the Nasuverse one after another.
In the end, the only ones who stayed by Rowan's side were Medea and Nero. Even King Hassan left.
As for the One Piece side, only Yamato, Smoothie, and Cosette remained.
