Three days later.

"The one before, it was called the Scythe Fruit, right?"

In the cabin, Nami bit the tip of her pen and thought carefully for a while, then wrote down in her notebook the words "Scythe fruit, the eater's nails become longer, and it can emit a powerful wind blade...", and raised her head.

"That kind of miscellaneous fish, what do you remember. ”

Kirby was lying in the hammock, swaying Erlang's legs with a helpless expression.

"You can only send out the ability of the lowest-level wind blade, and I don't want it if I give it to me. ”

"What do you know!" Nami's eyes suddenly widened, and she glanced at Kirby angrily, and said with a straight face:

"I'm recording a logbook! Every capable person has the need to keep a record!"

"Ah~ah~ It's up to you, the trouble is dead, this kind of thing, just leave it to the navigator. ”

Kirby scratched Red's little belly, and in the other party's eyes that wanted to refuse and welcome, he smashed his little finger twice in his mouth.

"I'll do it if you don't need to say it!

Nami stood up suddenly, her hands crossed in front of Kirby.

"Do you know that as a lady, you are very indecent and indecent like this!"

"I'm not a lady!"

Kirby rolled his eyes, but sat up straight, retracted his cocked legs, and jumped out of the hammock.

The men who stared at the base of their thighs with big eyes and a glance at the "absolute realm" looming at the base of their thighs suddenly sat up straight, their eyes more serious than the other, as if they were literary and artistic young people reading world classics...

Staring intently at the empty table.

"Ahh It's..."

Nami rolled her eyes and spread the map in her hand on the wooden table, pointing to a towering hill with one hand.

"Do you know where we're going next?"

"Huh?!"

Everyone froze for a moment.

At this moment, Usopp's exaggerated call came from outside the cabin -

"Nanana... There's a big dark cloud ahead! A storm must be coming!"

Usopp pinched his goggles with his fingers and screamed.

"Hmm—" Nami nodded, looking at the map in her hand.

"It's like we're back on course... Almost, it's almost to the Red Earth Continent, right?"

"Ahhh

"There's a great voyage ahead, right!" Luffy excitedly hugged Sanji's neck, showing a mouthful of big white teeth, and smiled happily.

"Finally entering the great waterway!! Lalalala Sanji!!"

Bang Bang Bang!

Luffy happily patted Sanji on the shoulder, and the cigarette butt in the man's mouth was shaken to the floor, emitting a wisp of green smoke.

"Ahh

Sanji turned around angrily and kicked Luffy in the face, picked up the cigarette butt that had not yet burned out, rinsed it with water, and threw it in the trash can on the side.

Turning around, Sanji took out another cigarette with a serious face, lit it with a loud click, took a sharp puff, and said:

"I know, upside down mountain, right?"

Smoke encircled the man's face, revealing vicissitudes in his eyes.

"That's right!"

Smack!

Nami patted the map on the table, grimacing, and pointed to the red hill above the map.

"But it's a little weird here. ”

"I've heard of it before, and it's drawn on the map, but if that's the case... It's a little too exciting..."

Everyone looked away—

There was a great mountain peak, divided into five pieces by five stout streams, two of which crossed, and from the center of the two lines branched out a thick line, which led to the great route.

The four directions to which those two lines point correspond to the east, south, west, and North Sea.

"If that's the case, the entrance to the Great Voyage is on the mountain!"

Nami clicked to the intersection of the top of the mountain, where the currents from the four seas converged.

"Mountain?!"

Luffy bit down on the empty glass, crossed his legs in the chair, and tilted his head.

Zoro: "Do you want us to crash into the mountains?"

Sanji: "What do you mean?"

"I don't think it's likely, either—" Nami looked up at the group and continued to focus on the map.

"But that's exactly what the map says, you see—" Nami pointed to the line that belonged to the East China Sea.

"There's a canal sign here, which means that..."

"In other words, the water there flows against the flow to the top of the mountain!" Kirby stood up, her eyes falling on the quaint map, the familiar smell of the map made of parchment, reminding her of the times when it was once prosperous.

"We have to climb up the hill along the river. ”

Luffy: "Oh! That looks like it's going to be fun!"

Sanji: "No, whether it's a canal or a mountain, it's just unscientific for a boat to climb a mountain." ”

Nami: "That's how it was drawn on the charts, I believe in them!"

Sanji: "Ah~ That's it! What Miss Nami said is the truth!"

"Hey, hey," Zoro said suddenly, "If I remember correctly, this is a nautical chart that I stole from Bucky, right?"

"Is it reliable?"

"Compared to this ——!," Usopp, who had been silent before, suddenly cried out, "Zoro, hurry up and help me take the helm!"

"What?!" Zoro glanced sideways, "don't you even have the strength to take the helm, really!

The man rolled up his sleeves, revealing his strong muscles, and stroked the small sheep-headed rudder.

However, just after exerting the force, there was a brief stiffness on Zoro's face.

"This..."

"Do you feel it, currents—" Usopp blushed, all the strength he needed to feed, but the rudder remained still.

"The currents are so strong!"

Zoro nodded affirmatively.

"Huh?!" Nami, who was staring at the map, suddenly stood up, "What did you say?!"

"Ahhh~ No way, the current is indeed too strong. Sauron scratched his hair, looking helpless, it was not that he couldn't break the rudder, but that, according to the strength of the current current, even if he broke the rudder, I am afraid it would be impossible to change the direction of the voyage.

"The currents... Ocean currents..."

Nami rolled her eyes and muttered a few words, and suddenly, as if remembering something, her eyes lit up.

"I see!"

Luffy: "What?"

"Sure enough, I still have to climb the mountain!" Nami nodded affirmatively, "Look here!

Nami pointed to the canal near the East China Sea on the map.

"The 'guiding light' definitely refers to this place! If the powerful currents of the four seas are all rushing towards this mountain..."Nami's fingers slowly moved up the Tokai Canal until they stopped at the intersection of the two lines.

"These four currents would go up the canal, collide at the top of the mountain, and finally flow to the Great Route. ”

"Since Upside Down Mountain is a winter island, the currents that crash into the Red Continent will dive deep from the surface of the water, and if you make a mistake and miss the opportunity to enter the canal, the Golden Merry will crash into the rock wall of the Red Continent!"
