Marine Base, Zephyr's courtyard.
Zephyr sipped his tea as he taught Christa.
Christa was still too young for high-intensity training.
So Zephyr mainly trained her Observation Haki and taught her the basics.
Right now, for instance, he was teaching her some common knowledge about life at sea.
"Grandpa Zephyr, is this Log Pose you're talking about pretty?"
Christa blinked and asked.
"It's not a question of whether it's pretty. It's really one of those, those very common things.
In the Four Seas, you can still rely on a navigator's knowledge to find your way, but on the Grand Line, only a Log Pose can lead you to your destination."
Zephyr explained very earnestly.
He was tough on the Elite Camp trainees.
But with Christa, he always had endless patience and smiles.
He couldn't even bear to raise his voice at her.
"Ohhh—"
After drawing out that long "oh," Christa asked curiously:
"Then what if I want to find a specific person? Can a Log Pose do that?"
Zephyr laughed and said:
"Haha, no, it can't! A Log Pose only records an island's magnetic field.
But there's a special tool for finding people too. It's called a Vivre Card."
"A Vivre Card?"
"That's right! Mix someone's fingernail into the materials, and you can make a Vivre Card.
The Vivre Card will always point toward its owner, so you can follow it to find the person you're looking for.
Ah, speaking of Vivre Cards, I happened to get Randall to let me make his recently.
That boy really never lets me stop worrying."
To avoid another situation where he couldn't find Randall, Zephyr had specifically asked him for a fingernail clipping.
As he spoke, Zephyr rummaged in his inner pocket and took out a piece of paper to show Christa.
Christa accepted
