I've Already Become An Admiral And Now The System Shows Up?

"Top-tier powerhouses might not have mastered Conqueror's Haki Enhancement, but to master its power, one must first elevate their Conqueror's Haki to an extremely high level."

"If light gold and normal gold aren't enough, then keep upgrading!"

Kenji made up his mind. This time, his priority was to upgrade [Conqueror's Haki], determined to acquire the signature power of top-tier powerhouses: Conqueror's Haki Enhancement!

But the problem was, he only had 3 Assignable upgrade opportunities at the moment.

"Currently, [Conqueror's Haki] trait is 'Super Blue' rarity… this could work with another mission reward."

Kenji's mind stirred, and he brought up another side quest.

"Is the direct advancement reward not affected by the depth or rarity?"

"If I can advance [Conqueror's Haki] once, it should be fine."

Kenji's eyes flickered, a plan already forming in his mind.

"First, upgrade it once…"

He stared at [Conqueror's Haki], his mind driving him to press the '+' sign behind the trait, only pressing it once.

[Your Conqueror's Haki (Super Blue) has been upgraded to Conqueror's Haki (Light Purple)!]

In his vision, [Conqueror's Haki] flashed with light, the blue fading, turning to purple.

"That's enough." Kenji immediately stopped, nodding with satisfaction.

The moment [Conqueror's Haki] advanced, he could clearly feel the increase in the power of his Conqueror's Haki within him.

When a trait advances, its strength receives a huge boost.

"Now, for the other reward…" Kenji put away the data panel and glanced at the side quest again.

Then, he turned his head and looked towards Whitebeard and Sengoku's battlefield, finding that the two were still fighting fiercely, showing no signs of stopping.

As long as the two did not stop, the war would naturally not be considered over.

"Bring the warship closer!" Kenji turned and ordered.

At this point, the warship had been largely repaired, with some damage to the hull temporarily patched up. While the overall strength of the warship might not compare to when the battle first began, it was perfectly capable of continuing to fight.

As the warship changed course and sailed at high speed, it soon entered the turbulent battlefield.

Along the way, under Anna's command, the soldiers rescued Marine personnel who had fallen into the water.

These were all warriors from Tsuru's disintegrated warship.

And Tsuru, as a Devil Fruit user, was barely maintaining her stance on a piece of the ship's wreckage with the help of her adjutant and other officers.

The previous battle had severely depleted her stamina, making many of her techniques difficult to employ.

Kenji raised his hand, emitting Armament Haki to resist the invisible shockwaves. His Armament Haki was extremely strong, allowing him to emit Armament Haki over a long distance.

The warship was unaffected by the battle's aftermath, successfully reaching the location of Tsuru and the others.

"Admiral Shirojishi…" Tsuru boarded the warship. Upon seeing Kenji, she first thanked him, then her expression became somewhat embarrassed.

"I couldn't help you all, and even caused you trouble… I am very sorry."

After some conversation, Kenji learned that Tsuru had intended to support Sengoku, but unfortunately, her warship had been severely damaged in the previous battle, unable to withstand the shockwaves.

In fact, it wasn't just Tsuru's warship. Kenji's warship also couldn't hold up much longer.

At this point, they had not yet entered the core area of the battlefield, and the residual impact the warship was experiencing was not yet very strong.

When they approached the central area of Sengoku and Whitebeard's fierce battle, even if Kenji emitted Armament Haki to defend against the shockwaves, the surging giant waves of the sea could still smash the warship to pieces.

This could be seen from the state of the warships beneath Sengoku and Whitebeard's feet.

Sengoku's warship continued to crack, and Whitebeard's side was also not doing well, with the massive Moby Dick scattering broken wood and several masts snapped.

"Stop here!" Kenji instructed Anna to stop the warship at the edge of the battlefield's core area.

He intended to strike from a distance, but first observed for a moment.

Even with the stormy weather blurring his vision and from a considerable distance, Kenji could still clearly observe the battlefield, especially the two top-tier powerhouses engaged in fierce combat.

"That is… Conqueror's Haki infusion!"

Whitebeard and Sengoku leaped into the air, using Conqueror's Haki infusion at close range to clash, with lightning-like Haki traces scattering wildly.

The residual Conqueror's Haki from their full-power collision tore through the sea and sky, and only their immediate vicinity on the entire battlefield was illuminated by sunlight.

A massive current swept the roaring waves, but upon reaching the warship, it was blocked by a flowing Armament Haki.

However, the rolling waves caused the warship to sway violently, making it difficult for the Marine personnel on board to steady themselves.

At this moment, Kenji stood at the bow of the ship, his eyes fixed on the two figures in the distant center of the battlefield, seemingly gaining some enlightenment.

"Conqueror's Haki infusion… So that's how it is."

Conqueror's Haki infusion is essentially an advanced application technique of Conqueror's Haki, but this technique is very difficult to learn and master, with only a very small number of top-tier powerhouses being able to grasp it.

After Kenji's [Hand-to-Hand Combat] advanced to gold, it boosted his comprehension. With his improved understanding, observing Sengoku and Whitebeard's battle was highly beneficial at this moment.

Now, he vaguely felt that he could also do it. He could use infuse Conqueror's Haki.

"It should be like this… No, no, I'm using too little Conqueror's Haki…"

Kenji stood at the bow of the ship and began to try to wrap Conqueror's Haki around his fist. The overflowing Haki immediately knocked out more than a dozen Marine soldiers closest to him.

Seeing this, the other personnel on the warship quickly retreated, afraid of being inexplicably knocked out themselves.

"What is he… doing?"

Tsuru and the other officers were full of confusion, unable to understand Kenji's actions, but they did not go forward to disturb or stop him.

"…Still not working."

After multiple attempts, Kenji still couldn't master Conqueror's Haki infusion.

He wasn't disheartened, though. After all, even the protagonist Luffy needed guidance to master Conqueror's Haki infusion.

Kenji was entirely self-observing the battle, trying to comprehend it forcefully.

Due to his aptitude, Kenji had long extracted reliable experience from years of training. It's okay to be bad, just practice more.

At this moment, he repeatedly and carefully watched Whitebeard and Sengoku's battle, focusing on the details of their use of Conqueror's Haki infusion.

After a period of observation, he started to get a feel for it, vaguely touching upon an indescribable key point.

Bits of Conqueror's Haki, following that surge of inspiration in his heart, were released, flowing and intertwining.
