One Piece: Trainers on the Straw Hat Pirates

All these branches are fresh and alive!

This is an uninhabited area thousands of meters below the surface of the sea.

"Strange~ Although there are underwater plants in this world, these structures look like they should belong to terrestrial plants, don't they?"

"What exactly is this thing?"

Franky lifted his sunglasses, looking like a curious child.

However, after hearing his words, Crimson's eyes suddenly flashed, and she replied with a smile:

"Perhaps... what we are seeing are plants from the land."

"Huh? How is that possible?"

"Isn't this the underwater world, tens of thousands of meters deep?"

Uta was puzzled. She braced her hands on the railing and strained to look out, as if that would allow her to see the branches of the plants in the distance more clearly.

There's nothing to doubt~

Chi Hong smiled slightly.

“I suspect that these branches did not just come from the ground, and perhaps we have only seen them recently.”

Have you seen them?

Robin looked up in surprise.

"Red, you mean to say..."

"The branches of these plants come from the World Tree in Elbaf!"

“That’s right!” Crimson nodded with a smile.

"But... we're at least several hundred nautical miles away from Elbaf now, aren't we?!"

"How could the branches of the World Tree have spread to such a distant place!?"

That's why it's called the World Tree.

Crimson responded to his companions' questions in a calm tone, but he wasn't entirely certain.

After all, this was just a guess in his mind.

But Crimson's subconscious, with its superpowers and precognitive abilities, was telling him that his guess was very likely correct!

According to the records of the giants...

The World Tree, which is thousands of years old, already had the enormous and magnificent size it has today.

The time it has lived on this planet is very likely measured in tens of thousands of years.

Tens of thousands of years have passed. Even if someone suddenly told him that the roots of the Crimson World Tree had already enveloped the core of the entire planet, he might hesitate before choosing to believe it.

Ten thousand years is an unreachable period of time, even for the current Crimson Empire. Countless bizarre and wonderful things could happen during that time.

Moreover, the world they live in is full of fantasy.

The Merry continued its descent.

Once inside the dark passageway, the surrounding environment consisted of nothing but plant branches and twigs.

Perhaps the existence of this passageway is due to the presence of these plant branches.

Time slips away bit by bit.

So much anticipation that none of the Straw Hat crew paid attention to how much time had passed.

And so, under everyone's gaze, a light different from the Flash spell suddenly appeared in front of the passageway.

In an instant, the Straw Hat crew's nerves were on edge.

Crimson waved his hand, channeling his immense superhuman power into the Merry, further accelerating its already impressive speed.

"It's coming!" Luffy exclaimed excitedly.

Amidst everyone's anticipation, the Going Merry suddenly departed from the dark tunnel.

The faint light shone through the seawater onto the faces of the Straw Hat crew, yet it seemed so bright and dazzling to them at that moment.

"Wuhu~!!!"

Usopp and Chopper excitedly crossed their arms, seemingly waiting for Luffy's command to start celebrating loudly.

But just then...

Clang!

The steady Merry suddenly shook noticeably, causing Crimson and the others to momentarily lose their footing.

The next moment, the Merry, which was in the water, suddenly moved rapidly upwards after losing control of the superpowers.

Wave~

With a loud popping sound, the soap coating surrounding the Merry vanished abruptly.

The Straw Hat crew arrived in a mysterious and dreamlike place.

"Is this... Laugh Tale!?"

Looking at the "sky" above their heads, everyone's face showed an excited expression.

A hazy, iridescent cloud shrouded the sky, like the last veil before mystery, spreading across the entire space.

A faint, soft light fell from the iridescent clouds, illuminating the entire area in a dreamlike hue.

"How beautiful!" Little Chopper exclaimed sincerely, taking in the surrounding scenery.

For some reason, after entering this space, everyone felt inexplicably relaxed and joyful.

Because it was their first time there, even the incredibly powerful Crimson couldn't detect anything unusual.

I felt as if I had finally reached the end of my sea adventure, and I couldn't hide my surging excitement.

On the contrary, Robin, who also possesses superhuman abilities and an astonishing willpower, was the first to discover the problem:

"Everyone, something seems wrong!"

Robin suddenly spoke, drawing everyone's attention to her.

He then said again:

"There seems to be a power in the air here that is similar to that of the Elbaf Celestial Realm."

"I can feel... this force seems to be affecting us!"

"What!?"

After Robin's reminder, Crimson was the first to snap out of her inexplicable feeling of pleasure.

He immediately waved his hand, and his remaining superpower formed small superpower barriers, protecting everyone's bodies.

A moment later, the Straw Hat crew members gradually emerged from the inexplicably pleasant atmosphere.

"What's going on? Why did I just feel like bursting out laughing?"

"What happened, Crimson? Is it dangerous here!?"

"Be careful. After all, this is the final island that only two groups of people have visited in hundreds of years. Who knows what kind of accident might happen?"

"........."

"........."

As the inexplicable feeling of pleasure was swept away from everyone's minds, Zoro and the others instantly assumed battle stances, looking around warily.

After releasing the protective shield, Crimson quickly looked around, but ultimately found nothing else.

Uta, who was also a strong individual in terms of mental strength, slowly opened his eyes. After completing his examination, he murmured softly:

"It seems that apart from the fog in the air, there shouldn't be any other surprises here."

Red nodded, but still said, "Anyway, it's always better to be careful. I won't remove the protective shield; everyone should take care of each other."

Nami's eyes flashed as she surveyed the seawater below the Going Merry.

"Although the Merry did ascend for a while just now, it shouldn't have covered much distance, right?"

"So we should still be underground, beneath the deep sea."

"It's amazing that there's such an area deep underground in the sea."

Sanji exclaimed in surprise, then looked puzzled.

"Strange, why is there air here!?"

"I think it's because of that thing!"

Just then, Jinbe suddenly raised one hand and pointed to the distance diagonally upwards.

Everyone's attention naturally followed, looking in the direction Jinbe was pointing.

Immediately they saw... a dazzling light source shining through the dreamy, colorful mist in the sky, bringing light to the entire space.

Jinbe explained, "That should be... the same principle as the Giant Tree of Fishman Island, the Sun Tree Eve, which brings sunlight from outside into the area through the roots of the plant."

Franky had a sudden inspiration: "So, what's above this colorful cloud is actually one of the roots of the World Tree?!"

At this moment, many of the people in the straw hats had already guessed the reason for the appearance of this space.

Due to the expansion of the World Tree's branches, the accumulated rocks here were pushed away by the hard roots of the World Tree, forming an underwater cave.

Over countless years, the roots of the World Tree released gases into this space through respiration, including strange substances that could affect people's emotions.

Over time, the seawater in this area was displaced by the gas, making it a habitable zone in a different sense.

Crimson smiled slightly: "Interesting. I didn't expect the legendary final island to be hidden in such an area."

After a brief exchange, the Merry set sail again.

Crimson and the others have already seen...

Within this eerie cave, there was a thick, root-like structure perched in the center of the seawater.

Although it is called a tree root, it still comes from the World Tree.

Just a few tree roots intertwining together are enough to create a small island-like area here.
