In truth, it wasn't just Shanks. Most of the onlookers below had expressions suggesting trouble was brewing.
The world-shaking momentum of those two great deities was so intense that even with the barrier of Naruto's spiritual power, the pressure was suffocating.
For ordinary people with weaker constitutions, like Zeff's disciple Patty, it was simply too much. He rolled his eyes and collapsed on the spot.
Even Shanks's crew members, Hancock, and Stussy couldn't help but look grave in the face of a full-powered battle between two Emperors.
They also knew that with Naruto around, they wouldn't get hurt.
But knowing something and being unaffected by the scene were two different things.
Of course, if Hancock weren't pregnant, she might have been able to remain expressionless.
But now, she couldn't rashly use her full power.
As for the filial daughter Yamato… aside from feeling her blood boil with excitement and an urge to jump into the fray for a three-way brawl, she had no other thoughts.
Unlike the guests from the One Piece World, the reactions of those from the Ninja World were relatively muted.
Apart from Haku, Zabuza, and Kakashi, the other Jinchuriki weren't particularly shocked by this level of battle aftermath.
After all, the Tailed Beast Bombs they fired in their full Tailed Beast forms could achieve similar effects… perhaps even stronger.
At least Gyuki wasn't intimidated.
In fact, after seeing Kaido in his dragon form, it even wanted to test itself against him.
Jiraiya, Karin, and Sasuke, who had experienced the [God Tree War], were even less concerned.
This was nothing.
Even if you combined Big Mom and Kaido, they wouldn't be as despair-inducing as the God Tree and Kaguya.
If we're talking about size alone, Karin in her fully awakened form now dwarfed Kaido's several hundred meters.
And, as mentioned before, in mythology, the divine bird Garuda 'feeds on dragons'.
—As for Toneri…
He seemed completely out of it.
It wasn't his fault.
After all, when Naruto and Isshiki fought in space, they were tossing around multi-kilometer meteors.
Even Toneri himself had nearly sliced the moon in half with a Golden Wheel Reincarnation Explosion.
If anything, his understanding of Naruto's strength was the closest to reality among everyone present. In the eyes of others… even Karin and the others, Naruto's power was roughly at the level he demonstrated when defeating Kaguya.
Well, the so-called [Six Paths-Level] that forum warriors liked to talk about.
But in fact, after researching Otsutsuki Shibai's husk, even Naruto himself didn't know his own current limits.
Apart from Toneri and Naruto, these two 'extra-terrestrial combatants', if there was anyone else who could remain expressionless before this grand spectacle, it was the other instigator of this conflict.
"Gugu gaga…"
Little Adam wasn't scared at all. Instead, he was fascinated by the flaming dragon that had transformed in the sky. He clapped his hands excitedly, trying to reach out and grab that long, glowing thing.
The little guy didn't yet understand perspective and was simply immersed in the thought, "Why is that dragon so big?"
"Eh? Adam wants that?"
Naruto looked down at his son, who was waving his arms and shouting in 'baby talk', then grinned and picked him up.
During this, the diamond Homie, Eve, tried to stop Naruto from touching Adam, but the barriers it created meant nothing to Naruto.
Naruto's hand passed through without any hindrance.
"But that fruit has already been eaten by your Uncle Kaido… Hmm, should Daddy just beat Uncle Kaido to death?"
The bystanders twitched their mouths slightly upon hearing Naruto teasing his child with such talk.
Killing an Emperor just to please a child… he made it sound as simple as killing a chicken.
But considering who was saying this, they could only purse their lips and say nothing.
If someone else said something like that, it would be pure bravado. But if it was Naruto… it was actually possible.
Shanks sighed beside him, finally deciding he couldn't just let the two Emperors fight endlessly.
After all, this was Naruto's wedding.
"Right, this is your wedding. Aren't you going to step in and stop them?"
But in response to Shanks's remark, Naruto simply grinned and replied.
"No rush. Those two aren't young anymore. It's rare for them to have this much energy. Let them get some exercise."
In his words, he was treating Big Mom and Kaido like retired old folks taking a walk around the neighborhood.
"Hey, hey… I really wonder about you sometimes…"
Shanks shook his head, about to say more, when Naruto pointed directly ahead, interrupting him.
"Here, this matter is better handled by that guy."
Shanks followed Naruto's finger towards the still turbulent sea.
He raised an eyebrow, his Observation Haki reaching out, and a look of understanding appeared on his face.
Then, Shanks turned to look at Naruto.
"Are you sure that old man can talk those two down?"
But before Naruto could answer, a large ship encased in a bubble emerged from the seafloor.
Immediately after, a figure with white hair, wearing a cape and flip-flops, leaped swiftly from the deck.
This new arrival apparently also knew the art of sky-walking, ascending to a high altitude in a few bounds and positioning himself between Big Mom and Kaido.
"Whew, close call. Looks like this old man arrived just in time."
Despite his age, a deep, magnetic voice sounded. Then an unremarkable long sword was drawn, held horizontally before the two who were enjoying their fight.
"After all, this is that kid Naruto's wedding. Could I trouble you two to do me a favor and stop for now?"
Big Mom and Kaido's attention was caught by this man. Almost simultaneously, they called out his name.
"Rayleigh!"
"If you're not satisfied, this old man wouldn't mind stretching his legs with you both."
Rayleigh showed a confident smile, as if he didn't put two Emperors in his eyes.
As if he truly had the confidence to take on both at once.
Down below, upon hearing Rayleigh's words, Shanks's expression became somewhat strange.
'Wasn't that the line I usually used when mediating conflicts between major powers?'
'Uncle Rayleigh's intel was… really something.'
'Wait…'
He suddenly turned his head to look at Naruto.
"You bastard. You didn't intervene on purpose just to see this, did you?"
As he said this, Shanks felt a twinge in his teeth.
Because knowing that certain someone, he might actually have planned it that way.
Sure enough, Naruto simply nodded with a smile.
"See? That kind of line really only has style when an old man with enough life experience says it. You… are still far from it."
Casually putting down his old comrade, Naruto grinned, holding Adam to his chest, and gave his son's soft cheek a little peck.
This made little Adam somewhat unhappy. He unceremoniously slapped his father's face, then tugged hard at Naruto's already groomed long hair.
"Alright, enough playing with the kid for now. You're not really going to let Uncle Rayleigh handle both of them alone, are you?"
"That would be deliberate revenge…"
Shanks had every reason to believe Naruto would do it.
After all, back on the Oro Jackson, Rayleigh and Gaban had frequently pulled down Naruto's pants, forcing the young Naruto, who hadn't yet mastered his power, to be exposed.
Those two weird uncles loved doing such boring things. Shanks had endured plenty of it back then.
"Alright, alright, I know… Uncle Shanks is so annoying, isn't he, son?"
"Haa~"
"See…"
Shanks gave him a dirty look.
"Just go stop them already, you idiot. This is your wedding."
The moment Shanks finished speaking, Naruto's figure vanished.
An instant later, Naruto appeared before Big Mom and Kaido, still holding his son.
"Haha!"
Seeing Kaido's dragon body up close, little Adam burst out laughing with joy. He waved his arms and legs excitedly, not even caring that his father was holding him awkwardly.
"Sigh… about time you showed up, kid. This old man thought he might actually get taken out by those two."
Seeing Naruto appear, Rayleigh wiped his brow in a very theatrical manner.
Then, the old man got a clear look at Adam and immediately showed a look of amazement.
"Wow, this little guy looks exactly like you when you were little."
"Right! That's what I've been saying…"
The moment Adam was mentioned, Naruto completely forgot about the main issue and immediately started praising his son's cuteness to Rayleigh.
Ignored, Kaido frowned in irritation. Flames blazed around him, and he was about to roar.
"Hey! Who the hell is going to fight me! Stop dawdling, or I'll—"
His roar stopped abruptly.
At some point, a large hand was gently placed on the divine dragon's long horn.
"Hey, how about calming down a bit, Kaido."
Naruto, still holding his child, maintained his smiling expression.
But Kaido, whose entire body was now 'gravity-locked' by inexplicably appearing black spheres, felt as if he were buried deep within a stratum of incredibly dense rock. Even blinking was a struggle.
'How… is this possible!?'
