After confirming that Enel had not eaten the Logia Lightning Fruit, Kahn was in an exceptionally good mood.
If not for fear of startling the Boa sisters, he would have transformed into a heavenly dragon right then, further enhancing his physique.
Then he would have unleashed telekinesis at full power, lifting everything on Birka into the air to find the Logia Lightning Fruit as fast as possible.
Even so, Kahn—rarely—showed a distracted look in front of Robin and the four girls.
Because at that moment he was fully deploying his innate Observation, searching all over Birka for any trace of the Logia Lightning Fruit.
In addition, he used group heart-reading, eavesdropping every second on the islanders' conversations and their thoughts.
"Master, did you find something?"
Kahn's distraction was quickly noticed by Robin.
Since she'd met him, it was the first time she'd seen him look like that.
Knowing a proper maid shouldn't ask what shouldn't be asked, she still couldn't help speaking up.
"Mm."
Kahn came back to himself and said with a half-genuine, half-playful excitement, "Just now my Haki overheard some incredible intel. If it's true, our haul this trip might be even bigger than the Golden City."
The Boa sisters' eyes widened; they almost blurted out questions.
But when Robin shot them a look, the sisters swallowed their words.
Glancing at the passersby, Mary whispered, face alight, "Then don't stay with me shopping. Master, go take care of it."
"Mm. Master, you don't need to stay with me."
Robin nodded in agreement. "And Hancock can protect me. With your fruit ability and unmatched perception, you can keep us safe from extreme range."
"In that case, I'll split off first." Kahn had been about to suggest it himself.
They parted at a street corner.
Robin and the sisters continued to shop, while Kahn left the city for Birka's wild outskirts and focused wholly on tracking the Lightning Fruit.
Blending telekinesis with his unique perception was like having a god's-eye view.
His "gaze" easily covered all of Birka, and the cost—like Enel's mantra—was negligible.
If he wanted to, he could leave that perception running twenty-four hours a day.
He could also amplify the "view" by spending stamina.
The reason it cost stamina was the increased telekinetic output.
As Haki and stamina burned, Kahn focused on Birka's wilderness, searching any place that could hide a single fruit.
His sight swept clockwise, starting from the north of the island.
If there was a hollow in a sky-tree and darkness hid the interior, he increased his telekinetic output and, from extreme range, tore the whole tree up from the cloud-ground.
If his gaze passed over old ruins with wide cracks, he moved the entire ruin aside.
Wherever he looked, trees were uprooted, ruins floated into the air, and even the cloud-ground split open as if by invisible hands.
Such eerie phenomena sent countless sky-island beasts fleeing in panic.
Even some patrolling guards were badly spooked.
Among them was Enel, hiding in the northern wilds.
Since Enel was the destined next user of the Logia Lightning Fruit—and Birka's most likely person to find it—
Kahn began his search with the area where Enel hid.
Perhaps it was that mysterious thing called luck.
He'd thought it might take days to find the Logia Lightning Fruit.
But in just a few hours, within timeworn ruins, down a large crack, he found a blue-and-white fruit growing in darkness, fresh and unrotted despite the lack of sunlight.
Its surface was covered with distinctive spiral patterns.
That special fruit—the one called the strongest of the Logias—the Logia Lightning Fruit.
"Finally found it!"
The moment he located the fruit, Kahn—who hadn't even broken a sweat after hours of expenditure—let rare excitement show on his face.
Whoosh—
Without the slightest hesitation, he vanished from where he stood.
A shrill, arrowing rip of the air split the region as he shot toward Birka's northern quadrant.
Before he even arrived, he stopped.
Because the Lightning Fruit, wrapped in a telekinetic veil, was already streaking toward him at great speed.
Man and treasure met midway.
Catching the falling fruit, Kahn headed back toward the city.
On the way, from extreme range, he used telekinesis to "tug" at Robin—
A coded signal only he and Robin would recognize.
Receiving it while she was shopping for clothes with the Boa sisters, Robin showed no change outwardly, though a keen gleam flashed in her blue-black eyes.
She then shot Hancock a look.
After their time together, Hancock had developed a fine tacit understanding with Robin; she instantly grasped what her slightly younger yet elder-like mentor meant.
The Boa sisters feigned dissatisfaction and shook their heads.
Then they set down the clothes, and under the shopkeeper's regretful gaze, left with Robin and headed back to the inn.
When they returned to their suite, Kahn was already waiting inside.
"Hancock, eat this."
Before Mary and Sonia could voice their curiosity—
Kahn tossed a blue-and-white fruit toward Hancock, who stood behind her sisters.
As it left his hand, a blue telekinetic veil appeared, like invisible fingers, lifting the fruit over Mary and Sonia's heads and floating it before Hancock's eyes.
Seeing the distinctive spirals on its skin—so similar to the one they'd seen yesterday—the Boa sisters exclaimed, "A Devil Fruit?"
"Master, was that overheard good news… this fruit?"
Robin, for once curious, repeated Kahn's words from a few hours earlier. "An incredible piece of intel, a haul bigger than the Golden City… does that mean this fruit is extraordinarily precious?"
