Probably because this world is far more complex than the previous one.
So, Mont-d'Or's Book-Book Fruit can only simulate to this extent?
"Worororo! You noticed it too, these overly fake illusions, countless and too many to count, just looking at them is annoying!"
Kaido's voice echoed.
Shano lifted his head and happened to see the figure of his opponent suddenly swell, blue scales emerging on the surface of his skin, dragon horns growing atop his head...
In the blink of an eye, he transformed into a cyan divine dragon that blocked out the sky and covered the earth!
The cyan dragon, combined with these surroundings resembling a modern cityscape...
"Feels like I've crossed into the Dragon Ball World!"
Shano couldn't help but laugh out loud, "Hey, Kaido, when I gather the Seven Dragon Balls, can I come find you for a wish!"
Dragon Ball?
What's that?
Kaido furrowed his brow, not bothering to delve deeper, he orbited over the city, his body spinning rapidly like a top.
"Stop saying things I can't understand! Kid, witness with this fake world the power of this move!!"
As his speed increased, a terrifying tornado began to converge, and with Kaido's angry roar upwards, it erupted in all directions!
"With the wind rising straight to the clouds, destroy all creation in an instant... Tornado of Destruction!!!"
Boom!
Just in a moment.
The surrounding skyscrapers were cut in half as if made of paper, glass curtain walls shattered and fell, disappearing in a flash of white light before they hit the ground.
Where the tornado passed, most of the city was erased as if by a rubber eraser, buildings, roads, pedestrians, vehicles...
Everything was rapidly vanishing.
And Shano, standing at the forefront, naturally bore the brunt of the most terrifying wind pressure, forcing him to immediately cross his arms in front of his face to shield himself.
The feeling of the surrounding oxygen being drawn away wasn't pleasant, yet the tornadoes summoned by Kaido overlapped, growing more numerous and more powerful...
"This is endless, very annoying!"
His aggression surged, his arms suddenly spread wide, muscles tensed, Supreme King Haki surged forth like a flood, sweeping outwards!
In an instant, all the fierce winds were blown away!
Pa.
Shano clenched his fists tightly, grinning wrathfully at the giant dragon.
This level of... this ridiculous child's play might exhaust those thirty-billion Belly Super Rookies, but how could it possibly hurt him!
Additionally...
"Hey, isn't hand-to-hand combat more thrilling, Kaido! How could you suddenly switch from a Berserker to a Mage!"
In the shout of dissatisfaction, Shano suddenly vanished from the spot.
Bang!
The air was violently torn open, creating a vacuum passage, only to see his figure like an arrow leaving the bowstorm towards the sky, his fist entwined with black-red lightning, boldly rushing towards the cyan dragon's head!
"Anyway, first let's beat this damn divine dragon back to human form!"
...
Outside, atop Cake Castle.
Time flew by, in an instant, a day and a night passed.
Every so often, dozens of pages would be burned, and Mont-d'Or, exerting all his strength and struggling to maintain the operation of the story world, would become a few shades paler.
"Mama, I can't hold on anymore..." he implored, looking at BIGMOM.
"Even if you can't, you must hold on!"
BIGMOM glared over fiercely, with each hand grabbing a large cake, throwing the one in her left into her own mouth, and stuffing the one in her right crudely into Mont-d'Or's mouth, "It's nothing more than being hungry, eat until you're full and you'll have strength!"
"Oof..."
Mont-d'Or was stuffed so full of cream that he nearly choked to death, but under BIGMOM's pressure, he could only grit his teeth and continue to maintain his ability.
Thus, another whole night passed.
The morning of the third day was the originally scheduled end time of the tea party, and those guests of ordinary social ranking and status, after having breakfast, sensibly took their leave.
Most of them feared the Sea Emperors' battle affecting them, but dared not leave early, afraid of offending BIGMOM.
Thus, they spent the first two days on tenterhooks, and as soon as the tea party ended, they left in a hurry.
And the Charlotte family's children also got busy, some saw off guests, some went out on missions, some returned to their territories to guard, leaving Cake Island one after another.
In short, by the end of the third day, atop Cake Castle.
Aside from Endgame's crew, only a few Underworld emperors and a few Commanders remained, continuing to keep BIGMOM company, patiently awaiting the battle's conclusion...

Fourth day.
The simulated worlds created by the Book-Book Fruit had already been destroyed countless times.
At present, they were in a countryside village, a picturesque environment, buildings styled after the Wano Country, with a plaque bearing "Iga" hung at the village entrance.
Seems to stem from folklore over in Wano Country.
Shano wasn't sure of specifics, nor did it matter.
Because in this world, shortly after the battle began, this village was razed to the ground, replaced by a barren wasteland.
"Huff... Huff..."
He half-kneeled on the cracked ground, his chest heaving violently, sweat mixed with blood dripping from his chin.
Knuckles, arms, elbows... virtually his entire body, from head to foot, had parts twisted and deformed from prolonged intense battle, not yet fully restored.
But... those eyes remained as piercing as ever, burning with fierce fighting spirit!
In the near distance.
