No One Understands Devil Fruits Better Than I Do

Loi Amos, Marine Headquarters Captain, commander of the Detention Unit warship 'DT-31'.

Reputedly hailing from West Blue, he joined the Marines at age twenty and has served for eight years now.

His performance in the Marine Branch physical fitness tests was unremarkable, but after participating in the capture of the West Blue Devil Fruit user pirate 'Captain Rhino', his strength began to surge—this was not unusual; many Marine officers only started showing their edge after encountering a formidable foe.

Thereafter, he was specially recruited into Marine Headquarters, and after passing the recruit assessment, he voluntarily applied to serve in the Detention Unit.

—This was the extent of what the Marine members of the Detention Unit knew about Loi Amos.

But in truth, no one knew.

Loi Amos's real identity was actually a visitor from another world.

However, on one point, the Marine members were indeed correct.

That was that Loi truly had his own sense of justice.

"Ice cola is justice!"

Loi sighed with satisfaction as he happily downed a slice of pizza and a mouthful of ice-cold soda.

At this moment, he was simply staring at the hourglass on the table before him.

Just then, the hourglass finished draining.

And in his ear—

[Paramecia · Strong-Strong Fruit has been added to the Fruit Encyclopedia, current level LV1]

Such a voice rang out, and the illusory Light Screen before him also shifted.

It gradually transformed into an illusory book.

And now, on each page of the book, there were Devil Fruits of different shapes.

[Paramecia - Cage-Cage Fruit - LV1]

[Zoan - Ox-Ox Fruit: Great Rhino Form - LV1]

[Zoan - Dog-Dog Fruit: Dalmatian Form - LV1]

[Logia - Glimmer-Glimmer Fruit - LV1]

[Logia - Magma-Magma Fruit - LV1]

[Logia - Freeze-Freeze Fruit - LV1]

And on the newest page of the book, [Paramecia - Strong-Strong Fruit - LV1] had just been fully recorded.

Thus, the page was closed.

On the closed cover of the book, four characters were written—[Fruit Encyclopedia].

[Holder: Loi Amos]

[Current Encyclopedia Fruit Types: 19 (Paramecia - 7, Zoan - 7, Logia - 4, Special Paramecia - 0, Mythical Zoan - 1)]

[Fruit Slot Count: 2]

[Currently Equipped: Ox-Ox Fruit: Great Rhino Form LV1, Human-Human Fruit: Great Buddha Form LV1]

[Current Belly Held: 41.13 million]

"The Fruit Encyclopedia has finally collected nineteen Devil Fruits—only one more Devil Fruit left to unlock the third Fruit Slot, and this guy's 'Strong-Strong Fruit' is a pretty practical ability!"

"This trip wasn't a waste."

And at this moment, the words Loi muttered in his mind were undoubtedly something only he could understand.

That's right.

As a transmigrator, Loi also had his own system.

That was the 'Fruit Encyclopedia' he was now seeing.

As the name implied—this system was related to the unique product of the Pirate world, the 'Devil Fruit'.

The Fruit Encyclopedia itself had two functional parts.

The first function was recording and usage.

As long as he approached a Devil Fruit Ability User and spent some time with them, he could record their Devil Fruit into the Fruit Encyclopedia.

When the Ability User used their ability in front of him, the speed of recording that fruit would increase.

After acquiring the ability, he could use the corresponding Devil Fruit power through the Fruit Slots in the encyclopedia.

There was only one Fruit Slot initially, and every ten Devil Fruits collected would unlock an additional slot.

Of course, if Loi directly obtained a real Devil Fruit.

Then he could absorb that Devil Fruit and directly gain the corresponding LV3 level ability.

The second function of the encyclopedia was the enhancement of fruit abilities.

After a fruit was recorded into the Fruit Encyclopedia, its base ability level was LV1.

Then, Loi could consume a sufficient amount of Belly or equivalent treasure to strengthen and raise his fruit ability levels.

Beyond that, Luo Yi could also consume a smaller amount of treasure to temporarily unlock a Fruit ability at a certain level—the required treasure was roughly one-third of the normal unlock cost, but it only granted a duration of one hour.

Furthermore, it seemed that because Luo Yi hadn't truly eaten a Devil Fruit, the abilities he obtained weren't restricted by seawater or Seastone.

As for this golden finger of his, Luo Yi's assessment was simple.

"Ridiculous."

Exactly.

He understood well that the effects of the Fruit Encyclopedia were terrifyingly powerful.

It allowed him to wield multiple Devil Fruit abilities without fearing seawater or Seastone.

This was already a broad highway straight to the very peak of the world.

Don't think Teacher Kai's talk about "Haki surpassing all" meant much—wasn't he himself a user of a legendary Devil Fruit like the Fish-Fish Fruit: Azure Dragon Form?

So the question became.

On this sea, where was the safest place to obtain enough Devil Fruits?

For Luo Yi, the answer was simple—the Marines.

As a colossal force backed by the World Government, keeping the Great Pirate Era from spiraling completely out of control, the Marines had the highest number of Ability Users and the greatest access to them.

That was why Luo Yi chose to join the Marines and deliberately picked the unpopular "Detention Unit."

And the facts proved his choice was right.

Over these eight years, by coming into contact with Ability Users within the Marines and occasionally escorting Ability User criminals, he had already obtained a total of nineteen Devil Fruit abilities.

Among them were even the Logia abilities of the current Three Admirals, and the top-tier Mythical Zoan ability of Fleet Admiral Sengoku himself—the Human-Human Fruit: Great Buddha Form.

In terms of accumulating Fruit abilities, Luo Yi had already built up a decent foundation.

So now, the only problem he faced was.

"I need to figure out a way to make money."

The Navy Captain thought to himself.

Yes.

As mentioned before, his Fruit abilities required Belly to strengthen.

The specific prices varied wildly depending on the type of Fruit, but they shared one common trait—the stronger the Fruit, the higher the cost.

Based on Luo Yi's current summary, strengthening an ordinary Paramecia or Zoan Fruit to LV2 cost around 50 million Belly, LV3 required 200 to 300 million, LV4 needed 1 billion, and LV5's Fruit Awakening generally demanded tens of billions of Belly or more.

As for Logia, it was even more exaggerated. The ordinary Smoke-Smoke Fruit cost 300 million to reach LV2, 1.5 billion for LV3, 5 billion for LV4, and over 10 billion for Awakening—an astronomical figure.

Top-tier Logia Fruits like the Magma-Magma Fruit or Freeze-Freeze Fruit had even higher strengthening costs.

For reference, Luo Yi's monthly salary as a Navy Captain was around 300,000 Belly.

In his eight years with the Marines, even counting the allowances and bonuses from escorting prisoners, he had only saved a little over 40 million Belly.

"Here I am, a model youth who doesn't smoke, doesn't drink, and whose only hobby is drinking cola—and I still can't save money. Burp!"

Luo Yi belched and sighed.

He was genuinely troubled by this.

"No money!"

Who would've thought that the thing bothering him before and after his transmigration was the same?

"If it comes down to it, I'll just leave the Marines after collecting 20 Devil Fruits—become a bounty hunter or something. It means running around everywhere, but at least the earning speed is faster than in the Marines."

"And although all my current Fruit abilities are at LV1, if I can unlock a third Fruit Slot, it should be enough for at least the first half of the Grand Line."

Luo Yi calculated in his mind.

But just then—

"Boom!"

The cabin suddenly began to shake violently, and shouts came from outside.

Luo Yi quickly shielded his Ice Cola and yelled angrily, "What's going on? Who's at the helm? Hey—Hans! Do you want to get fired or what!?"

As he shouted, he hurriedly downed the rest of his cola, then opened the door and stepped out of the cabin.

What he saw was a chaotic deck and Marine soldiers raising their guns and firing.

Their aim was directed at the sea.

Under the moonlight of the pitch-black night sky, on the shimmering surface of the ocean, a massive creature was emerging from beneath the water.

It had the head of a lion, the body of a fish, and a length stretching dozens of meters.

Its enormous eyes burned like sparks of fire in the night.

"Captain Luo Yi, it's a Sea Beast—a large one is attacking us!"

Sergeant Fal rushed up to Luo Yi and reported anxiously.

"A Sea Beast?"

Luo Yi raised an eyebrow.

As a Navy unit long active in the Four Seas, the Detention Unit's warship naturally had its bottom coated with Seastone technology.

Under normal circumstances, Sea Beasts and Sea Kings wouldn't detect the ship's presence.

But occasionally, exceptions occurred—like when a coastal Sea Beast or a shallow-water Sea King surfaced too close and noticed this "iron lump."

"Yes! Looks like our luck is terrible."

Fal looked on the verge of tears.

But—

"Terrible luck? Isn't this great luck?"

Luo Yi cut him off. "I recall Sea Beast meat is quite valuable!"

"Wh-what?"

Fal didn't catch on.

But Luo Yi didn't answer him. "Everyone, cease fire—if you ruin the best meat, you're dead!"

"?" *N

All the Marine soldiers on the ship froze in confusion.

But as soldiers, they instinctively stopped firing.

"Sir, you—"

Someone started to ask a question.

Before they could finish, they saw Luo Yi's body move.

"Boom!"

He bent his knees, leaped, and then launched himself with explosive force!

The sheer power caused the entire warship to tilt noticeably in that instant.

Under the gaze of every Marine, Luo Yi's figure shot toward the massive Sea Beast.

"Captain Luo Yi!" *N

The Marines cried out in alarm.

But the next moment, their cries turned into screams of terror.

Because the Sea Beast had now noticed Luo Yi too.

"Roar!"

Its massive head let out a low growl, then slammed toward Luo Yi with tremendous force.

"It's over!"

"If he takes that hit head-on... even the Captain..."

"Prepare to rescue! Rescue the Captain immediately!"

The soldiers panicked.

But just a moment later, the sight before them nearly made their eyes pop out and their jaws drop to the floor.

Because there, under the moonlight, the Navy Captain streaked through the air, his coat emblazoned with the word "Justice" flapping in the wind.

He bent his elbow, then clenched his fist!

In the moonlight, every Marine saw his thick, steel-forged arm!

The muscles beneath it bulged like iron.

[Currently Equipped Fruit-1: Ox-Ox Fruit Model: Great Rhino LV1 - Weak Devil Fruit Ability. Grants the physique of a Great Rhinoceros, with body strength and muscle density far exceeding normal humans.]

[Currently Equipped Fruit-2: Strong-Strong Fruit LV1 - Weak Devil Fruit Ability. Amplifies muscle strength by 5 times.]

Many knew that Zoan Devil Fruits granted their users a powerful, beast-like body.

The gladiator Antoria also knew that the Strong-Strong Fruit could massively enhance a user's muscles.

But what happens when one person possesses both the base physicality of a Zoan and the muscle amplification of the Strong-Strong Fruit?

This moment was the answer.

"Boom!"

Luo Yi threw a punch!

The gale driven by his immense force even pressed a massive 'trench' into the sea surface before him.

The next moment, his fist collided with the Sea Beast's head.

Then, every Marine soldier saw it—

That enormous Sea Beast, over a hundred meters long, was actually sent flying by Luo Yi's single punch!

"Roar!"

It let out a mournful cry, crashed onto the sea surface, and fell unconscious on the spot.

Meanwhile, Luo Yi's figure landed atop the Sea Beast's head amid the Marines' cries of "Wha—huh—huh—huh—huh?!"

That's right.

This was precisely why Luo Yi wasn't too anxious even though all his Fruits were still at LV1.

Because—

"The stacking of Devil Fruits isn't as simple as one plus one—as long as you have a thorough enough understanding of enough Devil Fruits, even an LV1 Devil Fruit can unleash power beyond imagination!"

Luo Yi murmured to himself.

"And in this world, no one understands Devil Fruits better than I do!"
