Somewhere on the Grand Line, the Going Merry sailed onward.

Unlike their smooth sailing through East Blue thanks to Nami's exceptional skills, the Merry was currently experiencing utter chaos in Grand Line.

One moment, the sky above the sea would be clear and sunny; the next, thick fog would roll in, followed instantly by blizzards, thunderstorms, hurricanes—a relentless, unpredictable cycle of extreme weather with no respite.

"What is wrong with this sea?!" Even Nami, despite her talent, couldn't help but clutch her head, overwhelmed by the bizarre climate.

"Stay calm, Nami. This is the Grand Line. There's nothing wrong with your navigation skills. You just need to practice and verify things as we sail," Rowen reassured her gently, placing a hand on her shoulder with a warm smile.

Theory was just theory.

Without actually sailing the Grand Line, one couldn't truly grasp the terrifying nature of this sea. But adapting to this harsh environment, constantly pushing forward—that's how one grew stronger.

This applied to both navigation skills and Haki.

"We'll navigate together. Just remember one principle: sailing the Grand Line, you can't trust the wind, the clouds, or the currents. The only thing you can rely on—is this unwavering needle," Rowen stated seriously, pointing to the Log Pose on Nami's wrist.

Having already equipped Nami's Navigation and Climate Sense Traits, Rowen's own navigational understanding was now on par with hers. However, actually sailing the Grand Line still required practical experience.

"I understand, Rowen!" Reassured by Rowen, Nami quickly regained her composure.

Under Nami and Rowen's joint command, though still hectic, the Going Merry successfully navigated through the volatile stretch of sea. The weather finally stabilized.

Luffy and the others collapsed onto the deck, exhausted. Sailing through such conditions required constant course adjustments, leaving absolutely no time for rest.

"Phew!" Vivi leaned against the cabin wall, letting out a breath. She watched Rowen discussing navigation with Nami, noticing the genuine smile on Nami's face, and pressed her lips together thoughtfully.

A pang of envy stirred within her.

During the recent chaotic navigation, Rowen and Nami had commanded the ship together.

Vivi had also learned that Rowen had specifically learned navigation for Nami.

This resonated deeply with Vivi, who, for the sake of her country, had infiltrated Baroque Works with Igaram at the young age of sixteen.

Though Vivi was incredibly strong-willed—otherwise she wouldn't have abandoned her princess life to undertake such a dangerous mission—she was still, at heart, an eighteen-year-old young woman with inherent vulnerabilities.

Especially after discovering Crocodile was behind Baroque Works, the overwhelming despair had magnified that vulnerability immensely.

And then... she met Rowen and his crew.

Vivi sat on the deck, her gaze drifting towards Rowen.

Even now, it felt surreal, like a dream. Just when she felt most hopeless, a great pirate with a bounty over 100 million appeared—a powerful Logia Devil Fruit user, no less!
