The Roger Pirates could roam the New World freely, so naturally, they had their own sources of information.
Shakky, for instance, along with some other connections.
So when Zesi left the Roger Pirates, he already knew the Whitebeard Pirates' whereabouts.
In fact, this was no secret. The Whitebeard Pirates never hid their movements.
So Roger and the others had hardly needed to make any effort to find out where Whitebeard was.
With a wine jar larger than himself strapped to his back, Zesi stepped on the air, racing through the sky.
In just half a day, he reached the waters where Whitebeard had been seen.
Standing in the air, Zesi looked around.
The Roger Pirates only knew the general waters where Whitebeard was active.
After all, this was the sea. Without someone keeping watch, it was impossible to track the Whitebeard Pirates' precise location.
On this vast ocean, an ordinary person would have struggled to find the Whitebeard Pirates directly.
But Zesi was no ordinary person.
Of course, even Zesi's Observation Haki could not scan such an enormous area, but Observation Haki was not his only means of searching.
He took a deep breath, and waves of vibration radiated from his body, spreading in every direction.
"Found them!" A short while later, Zesi's eyes lit up, and he flew swiftly in one direction.
"What's that?"
"It looks like a person!"
"A person? How could a person fly through the sky? Is he a Devil Fruit User?"
"Could he be a Marine? I remember one of the Marines' Six Powers lets them run through the air like that!"
"Look, he's getting closer! He seems to be coming for us!"
Several crew members aboard the Whitebeard Pirates' ship suddenly spotted a figure flying toward them through the sky and cried out in surprise.
"Careful. I can sense something dangerous about him. Is he an enemy? Let me cut him down first!" said Kozuki Oden, who had sailed out to sea with Whitebeard and was now the Whitebeard Pirates' Second Division Commander.
As he spoke, he had already drawn both swords.
"Oden Two-Sword Style: Togen Totsuka!" Two slashes formed a cross and hurtled toward the figure flying in from afar.
"Wait, he doesn't seem to be an enemy!" At that moment, Marco realized the approaching person did not seem to be an enemy.
Unfortunately, Marco spoke too late. Kozuki Oden had already charged out behind his slashes.
"Hahahaha! The Whitebeard Pirates' welcome is as enthusiastic as ever!"
The newcomer was none other than Zesi. Holding the wine jar in one hand, he extended his other hand and pressed it toward Kozuki Oden's cross-shaped slash.
An immensely dense layer of Armament Haki coated Zesi's palm.
Before his palm even touched the slash, an invisible force had already collided with it.
The collision of the two powerful forces sent the surrounding air trembling.
"It... it split open!"
The collision tore a gap through the clouds overhead, as though the sky itself had split open.
"Hmph!" Zesi snorted, adding the power of the Tremor-Tremor Fruit to his palm.
Overfrequency Vibration!
This was Zesi's original way of using the Tremor-Tremor Fruit, distinct from Whitebeard's.
Even though he had spent years constantly using the Tremor-Tremor Fruit to train his body,
Zesi's body still could not compare to Whitebeard's.
He still could not unleash devastating blows, Air Quake, and Seaquake as freely and without restraint as Whitebeard.
Besides, even Whitebeard had ended up with a body full of hidden injuries from unleashing his power so violently and without restraint.
When he was young, his formidable constitution made them little concern, but once he grew old and his stamina declined, those accumulated injuries would all flare up at once.
Zesi did not want to end up like Whitebeard, relying on IV drips to sustain his body in old age.
So from the very beginning, Zesi had chosen to use the Tremor-Tremor Fruit with greater finesse.
After years of development and refinement, it had finally become his current Overfrequency Vibration.
As the name suggested, Overfrequency Vibration meant vibrations at an extremely high frequency.
Zesi did not use the Tremor-Tremor Fruit with straightforward, brute force like Whitebeard.
As the saying went, what was too rigid would break. Even Whitebeard could not withstand it.
But without force, vibrations could not display their power.
To bring out the Tremor-Tremor Fruit's power, Zesi had chosen to increase the speed of its vibrations.
Even vibrations of only average strength could produce considerable power if they occurred hundreds or thousands of times in an instant.
Examples included Soru and Rankyaku of the Six Powers, as well as Zesi's Wave-Stepping Flash.
The accumulated recoil was enough to accelerate him to a terrifying speed in an instant.
What if he increased those vibrations to ten thousand, a hundred thousand, a million, or even ten million times per second?
At that moment, the vibrations in Zesi's palm were oscillating rapidly at around a hundred thousand times per second.
The air beneath his palm immediately warped. With a slight clench of his hand, Zesi crushed Kozuki Oden's slash.
At that very moment, Kozuki Oden reached Zesi.
Zesi raised the fist he had just clenched and punched.
His fist collided with Kozuki Oden's twin swords.
Oden felt everything around him warp as Zesi threw that punch, followed by an endless surge of force.
Oden was sent hurtling backward, unable to stop himself.
Everyone in the Whitebeard Pirates gaped in astonishment.
Their powerful Second Division Commander had been sent flying back even faster in the blink of an eye.
He slammed heavily onto the deck, smashing a large hole through it.
At that moment, Zesi descended from the sky and landed aboard the Moby Dick.
As Zesi landed, an overwhelmingly domineering presence radiated from his body.
"Hey, what's going on?"
"What happened?"
"I don't know! They just passed out for no reason!"
Some of the weaker crew members of the Whitebeard Pirates fainted for no apparent reason.
"No need to make a fuss. They just couldn't withstand the pressure of Conqueror's Haki and passed out!" a voice said at that moment.
"Yo, Marco! Long time no see!" Zesi greeted the man who had appeared.
