Zephyr could fully understand Sengoku's excitement about the emergence of a new king.
The Navy Headquarters urgently needed a new king with the Conqueror's Haki to succeed Sengoku.
Even though Sengoku was still at his peak.
"After I finish reporting, I'll head back and see if I can help Rosen awaken his Conqueror's Haki."
Zephyr said seriously to Sengoku.
Although he himself didn't have Conqueror's Haki, as a former Admiral and chief instructor of the Naval Academy, he still had his own methods to test for the king's qualifications.
It might not be 100% effective, but at least it was better than nothing.
Bulu Bulu—
Just as Zephyr finished reporting and was about to leave, a Den Den Mushi in his pocket rang.
"Hello, this is Zephyr."
Zephyr paused, took out the Den Den Mushi, and answered.
"Teacher Zephyr."
"Come back quickly."
"Big trouble at the Naval Academy."
The voice of Yamakaji came through urgently.
"What happened?"
"Did someone master the Armament Haki already?"
"Is it Gion? Or Tokikake?"
Zephyr stayed calm.
He could see at a glance that Gion and Tokikake were both monsters with Admiral-level potential, just like Sakazuki, Borsalino, and Kuzan.
Learning Armament Haki in a day was normal for them.
"Neither."
"It's the Conqueror's Haki."
"Just now, someone suddenly unleashed Conqueror's Haki at the academy, and the range was massive. Almost every student in the classroom fainted on the spot."
As soon as Yamakaji finished speaking—
Sengoku, Garp, Borsalino, and Kuzan all stood up at the same time.
They rushed out of the Fleet Admiral's office together, heading straight for the Naval Academy.
After hearing Zephyr's report just now, they knew even more clearly who the source of this Haki was.
"A new king has finally appeared in the Navy."
Sengoku's voice was trembling with excitement.
If it had just been an ordinary Conqueror's Haki awakening, he would have been happy but still calm.
However, after hearing Zephyr describe Rosen's monstrous Haki talent—
Even as Fleet Admiral, he could not stay composed.
He was desperate to meet the new king.
"I knew it."
"How could a monster born for Haki not possess the king's qualifications?"
Borsalino turned directly into light, transforming into a golden beam and flashing past everyone, arriving at the academy first.
In terms of sheer combat strength, he wasn't necessarily the strongest among them—
But in terms of speed, he was definitely the fastest in the entire Navy.
"Let me see."
"Mm!"
"As expected, more than 90% of the academy's students are unconscious."
Suspended in the air above the Naval Academy, Borsalino looked down.
Students had collapsed in the corridors and classrooms everywhere.
"Tsk tsk! Even the air is filled with that wild Conqueror's scent."
"This is his first time awakening Haki, and he did it on his own?"
"This student, whom I've never even met— terrifying!"
Borsalino was about to use his Observation Haki to lock onto the source when he noticed something unbelievable.
The Conqueror's Haki that had just enveloped the entire academy—
It didn't dissipate.
It was shrinking.
Yes— shrinking.
Deliberately being controlled to pull back and avoid causing large-scale casualties.
"This… am I hallucinating?"
Borsalino almost lost control of his elemental form and nearly fell from the air.
After steadying himself, he couldn't help but rub his eyes and look again.
The Haki was still shrinking steadily.
"No way…"
"He just awakened this Conqueror's Haki…"
"And he's already surpassed the beginner level, rapidly advancing into intermediate mastery?"
Borsalino's jaw dropped, his face filled with horror.
He had seen countless pirates with kingly qualifications.
He had even defeated many.
But someone like Rosen— he had never seen before.
"Borsalino, what are you spacing out for?"
Suddenly—
A loud swoosh split the air.
Garp used Moonwalk and came to stand next to Borsalino, floating above the academy.
"Mr. Garp."
"See for yourself."
"You're just in time."
Borsalino pointed toward the teaching building.
"Impossible!"
Garp squinted, then opened his eyes wide in shock after sensing it.
"How long has it even been?"
"He's already able to freely control his Conqueror's Haki with pure willpower."
"Awaken Conqueror's Haki on his own… then instantly skip the beginner level… and push directly to intermediate mastery without anyone teaching him."
Garp's voice trembled.
Through Observation Haki, he saw Rosen's aura steadily controlling the Conqueror's Haki, shrinking it in an orderly fashion.
"That's definitely Conqueror's Haki."
"And what a massive range."
"Hmm? Why are you two standing here in a daze?"
At that moment—
Sengoku arrived.
His physical skills weren't as refined as Garp's. He hadn't activated his Buddha form, so he was slightly slower.
By the time he arrived, Rosen had already controlled his Haki to a contained range.
Without Observation Haki, Sengoku couldn't sense that Rosen's Conqueror's Haki had already crossed the beginner threshold and entered intermediate.
"Sengoku, you need to hurry up."
"Or there might not be much time left for you to teach him anything."
Garp cracked his neck and glanced at the stunned Sengoku.
"What do you mean?"
Sengoku frowned, not understanding.
"Watch for yourself."
"Use your Observation Haki."
Garp sighed and signaled Sengoku to check himself.
"So mysterious…"
Sengoku muttered but still obeyed.
His eyes flashed red, Observation Haki spread—
The next instant—
Sengoku nearly fell straight out of the sky.
"What?!"
"Didn't he just awaken his Conqueror's Haki?!"
"How is he already able to control it freely?!"
Sengoku staggered, nearly crashing to the ground.
The image of the composed Fleet Admiral vanished completely.
At this moment, he was utterly shaken.
Before, he didn't understand what Garp meant.
Now— he fully understood.
Conqueror's Haki had three stages.
Beginner — just awakened, unable to control.
Intermediate — can be fully controlled by will, controlling range, precision, and power at will.
Advanced — Haki is always active, capable of physically destroying opponents with pure pressure alone.
In the New World, most kings who had fought countless battles were at intermediate level.
Even the Four Emperors.
Only Roger, Rocks, and Shanks had achieved advanced Conqueror's Haki.
But Rosen?
The moment he awakened, he started chasing the level of kings who had cultivated their Haki for decades.
Perhaps his Haki's strength still lagged behind—
But in terms of control, he was no less than them.
This meant— apart from some advanced techniques of Conqueror's Haki, even Sengoku, the Fleet Admiral, had very little he could teach Rosen anymore.
Once Rosen took just one or two steps further—
Then, Sengoku himself…
Might have to visit Rosen for advice.
