After a busy day, Hades returned to the ship and neatly stored all the supplies in the warehouse.

Most of the materials collected at sea were within his comprehension, but the canvas bag and the eight books contained in it were very puzzling to him.

When he picked up the bag from the sea, it was already filled with water, and all eight books were soaked, and it was impossible to float on the water according to the weight of the package, but it was like a lonely boat on the sea, let the waves roll and never sink.

Hades researched for a while and found the key.

I saw a wooden board with a length and width of 20 centimeters pasted to the bottom of the canvas bag, and the whole package seemed to float on the water under the support of this wooden board. (note 1)

Stunned by his discovery, he threw it on the surface of the water and pressed it with all his might, but no matter how hard he tried, the plank remained motionless on the water.

Hades' eyes widened, when his nine-year obligation was in vain?

What is the buoyancy formula? F float = ρ liquid gV discharge

Obviously, buoyancy is related to the density of the liquid and the volume of the liquid discharged. But this is just ordinary seawater, and this small and delicate plank does not have much volume, so it can't produce such a large buoyancy anyway.

Hades tried to stand on the plank again, and the incredible thing continued, and the small plank actually supported his whole weight and successfully floated on the sea.

Realizing something, he returned to the ship and lay down on the deck in a "big" shape.

To be honest, he always wanted to know where he had crossed over, and for this purpose, even if he met a completely inhuman pirate, he would try to find out the news.

But now he knew that this was a world that even Newton and Archimedes could not control, because it was a supernatural world that violated the principles of physics!

Magic, fantasy, smoothbore guns, the Age of Discovery, that's all Hades thinks of as soon as he closes his eyes.

Thinking of this, he opened his eyes sharply and moved his gaze to the eight books.

In the absence of existing conditions, perhaps, this will be the fastest way for him to understand the world.

......

The sun rises and the morning light illuminates the endless sea, and the silent boats glow with magnificent colors in the light of the rising sun.

Seagulls flew across the water, perched on masts, and quietly watched the boy reading on the deck.

By the light of the sunrise, Hades flipped through the wet book in his hand at a glance, and he did not read the details of the book, but focused on the physical characteristics of the world, the species of creatures, and the degree of civilization.

Until, he turned to a fairy tale called "Rolando the Great Liar".

"Rolando the Great Liar" ......

The familiar name was like a fishing bait that was thrown into Hades' memory, and soon the answer that lurked in the depths of his memory was quickly fished.

Isn't this a storybook from One Piece?

Hades' hand holding the book trembled slightly, and the look in his eyes was first surprised, then relieved, and finally left a trace of helplessness.

He opened the book as if he had read it cursoryly, and sure enough, it was adapted from that Venbula. The story of Rolando's adventure to find gold.

So what to say...... Here it is...... The world of One Piece?

He crossed over and became a ship in the world of pirates?

The puzzle is solved, and many of his questions are solved, after all, there is a setting of ship spirits in the world of One Piece, not to mention the Queen Mother Anthem created by the Four Emperor Aunts with Homiz, the protagonist Straw Hats' former ship Merry has given birth to self-aware ship elves.

By the way, and the name of his ship - Hades.

There are three ancient weapons in the world of One Piece.

Heavenly King: Ouranos

Aquaman: Poseidon

And......

Hades: Pluto

Pluto is known to be the Hades of Roman mythology, while Hades is the Hades of Greek mythology.

The system gave him the name Hades, could it be that he was asked to challenge the Hades battleship Pruto, one of the three major weapons in ancient times?

What are you kidding, it's a legendary existence that claims to be able to destroy an island with a single shot, and he doesn't even have a single cannon on his ship now.

Hades shuddered and quickly shook his head, he didn't have a competitive mentality.

What he wants to do more now than to be an ancient weapon is to save his life and survive in this world that is difficult to be bound by rules.

After learning about the face of this world, Hades began to think about his own combat power.

The ship spirit in human form was only a seven or eight-year-old boy, and his strength was greater than he expected, but it could not sustain the strength of an adult man.

The good news is that Hades can disarm the ship spirit form at any time and choose to summon it again at any point on the ship, which takes less than half a second before and after, and in layman's terms, as long as he is on his own ship, he can teleport at any time.

Secondly, he can also use the ontological boat directly for hand-to-hand combat. It's like the last time you killed the pirate who lit the fire, you broke the mast of your own ship out of thin air and threw it at someone.

Hades experimented once, only to see him standing at the door of the warehouse where the supplies were stored, closing his eyes, feeling everything on the ship, and when he focused his consciousness on the stack of planks stored in the warehouse, he waved his hand, and the planks flew into the air, and under his control, they smashed straight towards the set target.

There was a loud crash, and the impact of a dozen or so planks crashing into one place at one place was comparable to the impact of a crashing wood into a city.

Sawdust flew wildly, and the thin wooden wall panels couldn't withstand the terrifying force, and a corner was broken.

Hades nodded his head in delight at first, but then worry rose again not long after.

Although the visual effects are good, I always feel that there is still some short, you must know that this is the world of One Piece, not to mention the fruit ability and domineering for the time being, just those strange races that are different from humans, they have innate abilities that are stronger than humans.

This level of attack is a threat to ordinary people, but it is not enough to deal with a slightly stronger enemy.

If he could have some metal and sharpen the tip like a spear or harpoon, it would be much more powerful under his control.

Hades is figuring out how to increase his combat effectiveness under the existing conditions, at least when he encounters pirates like last time, he will not become so passive.

PS: Super buoyancy wood chips: In the Alabastan chapter, Mr3 was defeated by Lao Sha and floated on the surface abnormally, which was obviously a drawing error, but when a reader asked a question on SBS, Oda (the author) joked that it was because Mr3 had a super buoyancy wood chip under him, and then in the Fish-Man Island chapter, Oda drew another super buoyancy wood chip in the manga along this stalk.
