Marineford is an island that serves as the headquarters of the Marines. It is where the Fleet Admiral and three other Admirals reside, along with many Vice Admirals and lower-ranking officers when they are not assigned to other bases.
There is also a town inhabited by the families of Marine soldiers.
The shape of Marineford is a crescent moon made entirely of brick and steel, with cannons lining the edges. However, since Akainu, known for his strict demeanor, took command, security at Marineford has been tightened.
Every corner is guarded by Marines with full armament, every inch of territory monitored by experienced spies.
Two years ago, Marineford suffered severe damage during the Summit War.
What is the Summit War?
There is no one who is unaware of the Summit War. After all, it was broadcast live via Den Den Mushi to the entire world and watched by countless people.
In summary, the Summit War was a significant battle that took place on Marineford between the Shirohige Pirates and their allies, led by the Yonko, Edward Newgate, against the entire forces of the Marine Headquarters, including the Shichibukai.
It was triggered by the capture and execution of Portgas D. Ace, a commander of the Shirohige Pirates' 2nd Division.
In this war, many events had a significant impact on the future world, from Ace's death to the arrival of Red-Haired Shanks, bringing about great changes.
Towards the end of the Summit War, the appearance of Kurohige was quite shocking. He managed to steal the Gura Gura No Mi Devil Fruit from Shirohige's hands. In the end, after the Summit War, he became one of the Yonko, replacing Shirohige. Although Kurohige had been a threat from the beginning, this further emphasized that he was not an opponent to be underestimated.
Returning to the main topic, Akainu took this opportunity to renovate Marineford to be stronger than ever before.
Now, Marineford has become one of the safest places in the world!
At least, that's what Akainu and everyone else thinks.
Under the cloudy night sky, Marineford stands firm with tight security, as if challenging anyone who dares to infiltrate.
The cold sea breeze blows, bringing news that the night will be calm as usual. However, none of the Marines on guard that night realized that an infiltrator was among them.
"So this is the Marine Headquarters... Not bad, Akainu's performance is better than Sengoku's in terms of comprehensively strengthening the Marine forces."
Eiji moved lightly among the shadows, each step unseen by the naked eye.
The inherent technique of the Gojo Clan, known as Limitless, gave him the ability to manipulate space.
Utilizing the memories of Lin Fan containing many anime, Eiji used his creativity to develop the Limitless Technique deeper than the ancestors of the Gojo Clan.
He is currently operating in a separate space from the real world. In this separate space, Eiji can move undetected, even by the most advanced sensors and surveillance in Marineford.
"By the way, my Stealth ability is somewhat similar to the Doa Doa no Mi Devil Fruit ability." Eiji thought as he casually walked along the corridor.
He often passed by Marines, but none detected his presence, not even the Vice Admirals.
"If that were Vice Admiral Garp, his Observation Haki might sense my Stealth. That man is one of the best Haki experts in the world. I have to be more careful."
Eiji had one goal: to find the Eternal Pose stored in Marineford, which could lead him to Egghead Island.
He had to avoid combat as much as possible. If unavoidable, he had to find the Egghead Eternal Pose first.
"Well well well... Where is the storage location of the Eternal Pose? The Marine Headquarters is vast, it's quite troublesome to check every room one by one." Eiji thought to himself.
He used the Limitless Technique to blend with the darkness. No sound, no trace left behind. He effortlessly penetrated the layers of security in Marineford, as if he were the shadow itself. In the separate space he created, he could see the real world, but the real world could not see him.
"Trouble!"
Seeing an old woman approaching, Eiji quickly hid behind the wall even in Stealth mode.
It was his natural instinct. Besides, the old woman was one of the individuals with dangerous abilities in her eyes.
Vice Admiral Tsuru!
"Hm? It seems like someone is staring at me."
Tsuru's steps halted, looking around, she saw no one in the corridor besides herself.
With sharp intuition, Tsuru used her Observation Haki to sense her surroundings.
"No one here? Could it just be my imagination? It seems like old age is starting to affect me."
Not finding anyone through Observation Haki, Tsuru lowered her guard.
This is Marineford!
No one has ever successfully infiltrated here. Even the Golden Lion Shiki, who once attacked Marineford out of anger after reading about Roger's execution, was defeated by Garp and Sengoku and ended up in Impel Down prison.
"Phew, that got me tense. I thought I was caught, turns out it was just a false alarm."
Seeing her leave, Eiji breathed a sigh of relief.
"Even though that old woman is on par with Garp and Sengoku, her main strength lies in the Devil Fruit. Although Tsuru can also use Haki, her achievements are not as great as Garp's. Advanced Haki is not easily mastered by everyone."
After a moment of thought, Eiji understood why Tsuru failed to detect him.
Stopping these thoughts, he continued to search for the storage room.
Thanks to his Six Eyes, he would quickly retreat if he sensed someone with a strong Spiritual Energy, indicating the other party's Haki was very strong. Thus, Eiji explored Marineford without being noticed.
After wandering aimlessly for three hours, he finally found the warehouse storing supplies and weapons.
In the warehouse, there were many swords and firearms, as well as Seastone handcuffs, and so on.
Of course, the object he was looking for was also there.
Eternal Poses neatly arranged on the shelves, numbering in the hundreds!
"Choosing Marineford was not wrong, here are many Eternal Poses leading to various islands in the New World."
Eiji quickly scanned the small inscriptions carved on the Eternal Poses.
"I found it."
After a few moments, he saw the Eternal Pose labeled Egghead, located at the top of the shelf.
Raising his hand, he used a small output of Blue. Then, the Egghead Eternal Pose was sucked into his hand.
"Eternal Pose successfully obtained. Before I leave, let's leave a gift."
A mischievous idea spontaneously came to his mind. Considering his relationship with the World Government, Eiji didn't need to show kindness to the Marines.
"Cursed Technique Reversal: Scarlet."
A dark red energy ball appeared at the tip of his finger. Eiji released Scarlet in the warehouse and teleported at the same time.
*BOOM*
Scarlet exploded, and flames spread quickly, burning everything in the warehouse.
The explosion was so loud that it prompted the Marines to come and check the situation. When they saw the warehouse on fire, they hurried to fetch water to extinguish the flames.
Fortunately, there happened to be a user of a Devil Fruit among them. So the fire was quickly put out.
Nevertheless, almost all the goods were damaged by the explosion.
When Akainu heard about this, he angrily slammed his desk. He ordered an investigation into the cause of the warehouse fire.
