Under the control of the Roy Pirates, Hachinosu began a methodical transformation.
Roy also informed his ally Kaido of the news.
Kaido also demonstrated his support for Roy, his ally, by immediately assigning a number of craftsmen, with King personally leading the team, to help Roy with construction.
Roy readily accepted Kaido's enthusiasm.
Standing on the top floor of the newly renovated palace, Roy looked down at the island that was being revitalized.
The sounds of construction echoed from the port area, while businesses gradually reopened on the commercial street.
In the residential area, children played on the newly renovated streets, their faces beaming with long-lost smiles.
Stella stood beside him and handed him a report.
"Captain, the detailed survey report for Hachinosu and the surrounding waters has been completed."
Roy took the report and quickly glanced at it.
Although Hachinosu enjoys a superior geographical location, its surrounding defenses have obvious weaknesses—aside from the main island and a dozen or so smaller islands, there are almost no islands within fifty nautical miles that can serve as a barrier.
The only valuable assets are a few uninhabited islands with mineral resources, but they are scattered and difficult to form an effective defense system.
"This defense is too weak."
Roy pointed to the chart and said,
"If someone attacks from multiple directions simultaneously, we will be forced to disperse our forces for defense. Furthermore, Hachinosu itself lacks natural defensive terrain."
Stella nodded.
"Yes, during Ochoku's era, the defensive fortifications were mainly based on those left over from the time of Rocks."
However, those structures were dilapidated and their design concepts were outdated.
Roy stared at the nautical chart in deep thought for a long time, a glint gradually appearing in his eyes.
" Stella, you will continue to be responsible for the island's daily management."
Roy turned and walked out.
"I need to go out for a while; it will probably take about a month."
"Captain, where are you going?" Stella quickly followed.
Roy stood on the edge of the terrace, gazing at the distant sea.
"Go find some 'barriers' for Hachinosu."
Before the words were finished,
His figure transformed into a streak of light, soaring into the sky and instantly disappearing into the clouds.
Stella looked up at the sky, though she didn't know what the captain was going to do.
But she believed Roy must have his own plans.
Roy flew at an astonishing speed over the New World.
His mental Telekinesis was fully unleashed, sensing every detail of the vast sea below.
His Observation Haki, combined with the power of his Telekinesis Fruit, allows him to accurately detect information such as seabed topography, island distribution, and resource conditions.
"I need an island of moderate size and with suitable terrain..." Roy muttered to himself, a clear idea already forming in his mind.
Three days later, he discovered an ideal island in the North Blue of the New World.
The island is oval-shaped, with an area of about five square kilometers. There is a small mountain in the center, and the surrounding area is a gentle coastline.
Most importantly, it's an uninhabited island with only some wild animals and lush vegetation.
"The first one."
Roy landed in the center of the island, placing his hands on the ground. A surge of powerful spiritual Telekinesis flowed out like a tide, permeating every inch of the island.
"Rise!"
With a low shout, the entire island began to tremble violently.
Rocks, soil, vegetation... everything was enveloped by an invisible force, slowly detaching from the seabed!
This is Telekinesis-Telekinesis Fruit, unlike Golden Lion's Float-Float Fruit, cannot make objects float indefinitely.
However, it is still possible to move large objects in a short period of time.
The island slowly rose into the air, with Roy hovering below it, using his Telekinesis to support this colossal object weighing millions of tons.
Roy calculated the optimal path and speed, controlling the island to slowly fly towards Hachinosu.
After two full days of flying, Roy finally moved the first island to the designated location on the outskirts of Hachinosu.
"According to the pentagram defensive formation, this is the first apex."
Roy slowly lowered the island onto the sea, creating towering waves.
He deliberately chose shallower waters to ensure the island could sit firmly on the seabed.
"Call..."
Roy let out a long breath, looked at the distant Hachinosu, and flew away again.
In the following month,
Like a tireless worker ant, Roy searched for suitable islands throughout the New World and then carried them one by one to the vicinity of Hachinosu.
He found a total of eleven uninhabited islands that met the criteria:
Five islands were positioned fifty nautical miles outside Hachinosu, forming a giant pentagram.
Each island is located at the apex of the pentagram, equidistant from one another, and can support each other.
The other five islands are positioned thirty nautical miles away, forming a slightly smaller inner pentagram.
It is angled away from the outer pentagram, forming a double defense system.
Roy placed the last island next to the main island of Hachinosu, only five nautical miles away.
The island is large and has a complex topography, with hills, forests, rivers, and a flat central area.
"This island will serve as the exclusive training base for the Roy Pirates."
Roy named the island " Trial Island ".
When the last island was in place, the defensive landscape of Hachinosu was completely transformed.
From a bird's-eye view, the two pentagram formations encircle the main island, like two indestructible barriers.
The Trial Island, like a loyal guardian, stands firmly beside the main island.
After completing all this, Roy returned to the Hachinosu palace and immediately convened a meeting of the core members.
"Captain, you've been through a lot this past month..." Tesoro looked at Roy's slightly tired but radiant face, and hesitated before speaking.
Roy waved his hand and brought up a brand new sea map of Hachinosu: "Take a look at this."
Everyone was shocked when they saw the completely new distribution of islands on the nautical chart.
"These islands... were they moved here by you, Captain?" Kyros asked incredulously.
"That's right."
Roy nodded.
"From today onwards, the defense system of Hachinosu will be completely transformed."
Roy explained the concept of the double pentagram defensive formation in detail:
"I named the five outer islands the 'Gold, Wood, Water, Fire, Earth' Five Star Fortresses."
Each fortress will be built as an independent defensive stronghold, equipped with gun emplacements, watchtowers, and garrison camps.
"Once an enemy attacks, the Five Star Fortresses can detect and intercept them immediately."
The inner layer consists of five islands, named the Five Star Outposts of "Wind, Rain, Thunder, Lightning, and Light".
Slightly smaller in size but more mobile, primarily responsible for reconnaissance, harassment, and rapid support.
"Undersea communication lines will be laid between all fortresses and outposts to ensure the immediacy of information transmission."
At the same time, I will have Master Tom set up Sea Train on each island to facilitate the rapid mobilization of personnel.
Roy's idea made everyone's eyes light up more and more.
"This defense system... is too perfect!"
Stella exclaimed in admiration,
"A double-layered defense, both inside and out, works in tandem, ensuring that any enemy coming from any direction must break through at least two lines of defense before approaching the main island."
Hawk Eyes looked at the nautical chart and added,
"Moreover, the island's location was carefully calculated."
From any fortress, one can simultaneously see two adjacent fortresses, creating crossfire coverage.
Crocodile exhaled a smoke ring.
"What's even better is that if the enemy wants to attack..."
We must first capture these outer islands. We can then rest and prepare on those islands, allowing us to significantly deplete the enemy's manpower.
Roy nodded in satisfaction.
That's exactly right.
"Now, we need to begin developing and constructing these islands immediately."
