I will use the ninja world to aid my cultivation of immortality.

The process continued for an unknown period of time, until finally the flattened elephant hide turned to ashes and scattered on the sea surface.

He sat cross-legged in mid-air in the center where the elephant skin had dissipated.

Naraku, having refined the last wisp of flesh and blood, slowly opened his eyes.

"It's still not enough."

A look of regret appeared in Naraku's eyes.

The flesh and blood of the elephant lord are indeed incredibly powerful, but the requirements of the "Blood Essence Technique" are even more exaggerated.

While refining the flesh and blood essence of the Elephant Lord has greatly advanced the "Blood Soul Technique," it is still far from achieving the minor success level.

Spread your legs and stand on the sea.

Naraku casually swept his leg across the boundless sea in front of him.

Zheng! ! !

A giant wave, resembling a mountain peak, shot into the sky, tearing through the sea as it rapidly flew into the distance until it disappeared from sight.

Starting from Naraku, the sea ahead reveals a canyon-like fissure that extends deep into the ocean floor and far into the distance.

Naraku smiled slightly as he observed the power generated by the cleaving wave.

Although the "Blood Essence Technique" failed to break through to the minor mastery stage, the extent of its improvement is undeniable.

With his current physique, a casual strike from him could unleash terrifying power.

Use the original entity as a comparison.

Without taking into account the projection of the bronze tower, his current strength is already approaching that of his original body when he first entered the Foundation Establishment stage.

In other words, the "Blood Soul Technique," which is close to the minor completion stage, is already comparable to the "Five Elements Technique" at the minor completion stage.

"For me, the Marineford War was not only a chance to reap a large number of Devil Fruits, but also a feast of harvesting flesh and blood," Naraku thought to himself.

"That bastard Morgans is just stirring up trouble."

In the Marshal's office, Sengoku slammed his hand on the newspaper on the table in annoyance.

As you can see in the newspaper, the best-selling World Economic Daily published an article about Naraku replacing Kaido as the new Fourth Emperor, and even bolded and enlarged the title "Dragon Slayer".

This is what angered the Warring States period.

He didn't care if Naraku became the new Fourth Emperor, but the title of 'Dragon Slayer' was too taboo.

Kaido is a user of the Blue Dragon Fruit. The title of Dragon Slayer seems to come from Naraku killing Kaido, but the problem is that the master of the World Government is also called a Celestial Dragon.

The phrase "slaying dragons" can represent Naraku killing Kaido, but it can also represent Naraku's intention to destroy the Celestial Dragons.

In fact, ever since the title of Dragon Slayer appeared, the World Government has contacted Morgans multiple times.

But Morgans always pretended to be stupid and even hid his whereabouts.

This action clearly shows that Morgans's designation of Naraku as the Dragon Slayer was not an accident, but rather a deliberate attempt to provoke trouble.

Anyone familiar with Morgans knows that this scoundrel loves to create big news to boost newspaper sales.

"Don't let anger cloud your judgment. Right now, our most important task is to deal with Whitebeard. We can deal with Naraku later."

The office was not occupied by Sengoku alone, but rather by a number of people.

The three admirals of the Navy: Kizaru, Akainu, and Aokiji.

Navy hero Garp.

Naval Chief of Staff Crane.

All of these key naval officers were present.

It was the crane that spoke at this moment.

She glanced at the newspaper on her desk and immediately understood the reason for Sengoku's anger.

But as she said, Ace's execution day is fast approaching.

During this period, everything else needs to be postponed.

"I think Naraku might be more threatening than Whitebeard. Based on what I saw that day, his strength already surpasses that of Whitebeard at his peak, and given his age, he will only become stronger in the future."

Borsalino, who was sitting with his legs crossed on one side of the office, suddenly spoke up.

And unlike his previous lazy demeanor, he now had a very serious expression.

When Kaido first appeared in Dressrosa.

Borsalino did not wait on the warship, but instead used the Glint-Glint Fruit to land directly in Dressrosa.

This allowed him to witness the entire battle between Naraku and Kaido.

The result of the observation was that after Naraku killed Kaido, he decisively turned into a flash of light and fled.

the reason is simple.

He feared that Naraku's killing spree would lead him to kill himself as well.

Sakazuki, sitting next to him, glanced at him sideways and said in a deep voice, "Regardless of whether Naraku's strength has surpassed Whitebeard's, after dealing with Whitebeard, I will apply to lead a team to Dressrosa to finish him off."

"Hey, have you forgotten? This guy became the World Government's recognized King of Dressrosa by taking advantage of Doflamingo. If you want to touch him, the World Government might not agree." Kuzan said lazily from the other side.

Sakazuki snorted coldly, turned to look at Kuzan and said, "The World Government's recognition doesn't change the fact that the other party is a pirate, and I believe the World Government couldn't possibly be unaware of the ambitions they've displayed."

“You can pretend you don’t even notice,” Borsalino interjected, his serious expression immediately vanishing as he reverted to his lazy demeanor.

"Ahem. We'll deal with Naraku's matter later. Let's continue discussing the execution arrangements." Sengoku quickly steered the conversation back on track as the three of them, including Sakazuki, were starting to get off track.

Soon, with Zhan Guo taking the lead and He assisting, the group returned the topic to the arrangements for the public execution.

Whether intentionally or not, the group avoided mentioning Garp, who remained silent and sat to the side throughout their conversation.

Ace was the second division commander of the Whitebeard Pirates and also Garp's grandson.

Outsiders might not know this, but how could the people of the Warring States period not be aware of it?

Even when Ace had just set sail as a pirate, Sengoku and Tsuru tried their best to resolve Garp's awkward situation and make Ace a Shichibukai.

Unfortunately, their efforts were completely in vain.

Ace not only refused to become a Shichibukai, but also joined the Whitebeard Pirates.

Time is like running water.

From the moment the Navy announced its intention to publicly execute Ace, the entire world fell into an eerie silence.

But this silence is only on the surface; beneath the surface, undercurrents are surging.

For example, the Navy mobilized its various bases and branches, drawing countless elites to gather at headquarters.

For example, the Whitebeard Pirates sank a Navy surveillance ship and secretly gathered many of their pirate crews.

Amidst this bizarre turn of events, the day of the public execution finally arrived.

On this day, the Navy assembled 100,000 elite troops at Marieford's Crescent Port, preparing to publicly execute Ace via live Den Den Mushi broadcast.

The same day.

A spatial vortex appeared above Impel Down.

He strolled out.

Standing in mid-air, suspended in the void.

Naraku looked down over the remaining Impel Down.

Impel Down is the first prison established by the World Government.

This city is located in the Calm Belt and was built around a giant vortex, along with Maryford and Enies Lobby.

Through the vortex at the center of the three, it is entirely possible to travel quickly between them.

In other words, if Impel Down is attacked, Maryford's navy can come to its aid as quickly as possible.

Of course, this does not mean that Impel Down's defenses are poor and that it requires support from the Marine Headquarters.

In fact, Impel Down, as the world's number one prison, has very strong defenses.

An entire naval fleet has been stationed on both sides of the port at sea for a long time.

Looking down at Impel Down, Naraku quickly and gracefully landed at the main gate.

He viewed the Marineford War as a hunting ground.

But this hunting ground is not limited to Maryford.

Impel Down is now also included in the hunting grounds.

Those imprisoned within the city were all heinous criminals.

Among them are not only those with strong physiques, but also countless Devil Fruit users.

With such a venue, how could Naraku possibly miss it?

With the Navy's attention now completely focused on the Whitebeard Pirates, it's the perfect time for him to hunt down Impel Down.

That's right.

He learned this from Blackbeard in the original storyline.
