I'm in One Piece, I'm Luffy's childhood friend

"The entrance to the Grand Line is a mountain."

Because the light of the lighthouse disappeared (because Crocus was "on vacation" in Lab's belly at this time.)

Luffy and his friends entered the kitchen and used the sea chart to confirm the route.

"Mountain?"

Luffy, Zoro, Sanji, and Usopp all had question marks.

"Yes, although I don't quite believe it, the navigation light is indeed erected on the upside-down mountain on the Red Earth Continent."

"So...so, we have to hit the mountain?"

Usopp swallowed his saliva. Since it's a mountain, how can we get through it?

"Of course it's impossible." ×2

Bai Yun and Nami said at the same time.

Nami looked at Bai Yun with a little surprise.

Bai Yun cleared his throat and continued.

"The Upside-Down Mountain is an incredible and dangerous mountain. It is the entrance to the Grand Line, so it is also called the [Incredible Mountain].

There are five sea channels on the Upside-Down Mountain, which are x-shaped, with four currents in and one out.

The currents of four of the sea channels flow to the top of the mountain.

The canals formed by the confluence of these four currents connect the four different seas of the East China Sea, the West China Sea, the South China Sea, and the North China Sea.

And the last canal flows into the Grand Line."

Everyone was stunned when they heard this. There is actually a canal that can climb mountains?

Nami was very confused, "Don't you know how to sail, Bai Yun?"

"But I am knowledgeable."

Bai Yun smiled back.

"It's okay to remember these dead knowledge. I asked my master before. Nami is still the one who has to rely on you, Miss Nami, for navigation."

Nami didn't react and picked up the sea chart. "So, according to Bai Yun, why do we have to follow the ocean current to find the entrance of the canal? Otherwise, if we hit the upside-down mountain, the ship will be destroyed and everyone will die."

"So... so dangerous!!"

Usopp hugged his scared self.

"If it's so dangerous, why do we have to enter from the [entrance]? Can't we turn south and find other routes?"

Zoro asked with his eyes closed and scratched his temple.

"Yeah, you know to go south. Brother Zoro has a good sense of direction."

Bai Yun will not miss any opportunity to be a jerk.

Zoro is almost used to it. He ignored him and waited for Nami's answer.

Luffy suddenly appeared.

"You are wrong."

Nami was still a little surprised, but it was normal for Luffy to know that he grew up with Bai Yun.

"Yes, there is a big reason..."

But Luffy didn't disappoint halfway through his words, "It feels good to enter from the entrance!"

Nami was speechless and punched Luffy on the head.

"It's not because of this!"

But before he could tell the reason, Usopp interrupted again.

"Hey, the storm has stopped."

........

Everyone came to the deck, but Bai Yun refused to go out.

"The weather is great, the sun is shining."

Sanji said with a cigarette in his mouth.

"Ah ... "Ah? Why?"

"Why do we need to row the boat back into the storm?"

The two of them looked calm.

But they were no longer calm the next second.

There was an earthquake on the Merry, and all kinds of huge sea kings of strange shapes emerged from the seabed.

The Merry was on the head of a sea king. Compared with it, the Merry was as small as an ant.

Luffy, Zoro and Sanji opened their mouths in fear.

Usopp foamed at the mouth.

Bai Yun was in the kitchen, and he was also scared when he saw these giant sea kings through the window.

"Oh my goodness, it's so scary to see it with my own eyes."

Miss Nami sat down and hugged the mast, "Because this is the nest of giant sea kings!!!"

.......

Usopp almost tried to fill the gap between the teeth of the sea king, no, it was not even enough to fill the gap between the teeth.

Fortunately, it was just "almost".

After a lot of trouble, the Merry finally returned to the storm.

Everyone lay on the deck, feeling like they had survived a catastrophe.

Bai Yun also walked onto the deck.

"Now you know why I didn't come out and tell Miss Nami that we couldn't take another route."

"Just now Zoro said that if we go south, we will enter the Calm Belt."

"The Calm Belt is a strip of land on both sides of the Grand Line, sandwiching the entire Grand Line in the middle."

"There is neither wind nor current in the Calm Belt. Once a sailboat enters here, it will lose power and be trapped.You can row it."

"And, as Miss Nami said, this is also the nest of super giant sea kings. If they just turn over, it will be a huge wave for us. It is precisely because of the existence of the Calm Belt that the pirates of the Four Seas must go through the Upside-Down Mountain to enter the Grand Line.

Not necessarily, it's a matter of strength. You can freely enter the Four Seas from the Grand Line through the Calm Belt, and vice versa, without having to go through the Upside-Down Mountain.

Therefore, many strong people also go through the Calm Belt. As long as you are strong enough, you can swim over it. "

"Swim... Swim over it!"

"That's too exaggerated, Bai Yun."

"I almost fainted when I saw those giant sea kings. How could someone swim over it?"

Usopp was still scared after thinking about it.

"I've said it all. It's a matter of strength. As long as you are strong enough, it's not impossible to do it."

.........

This time, Miss Nami personally watched the route outside.

Finally, they successfully arrived in front of the Red Earth Continent.

"I saw the [Incredible Mountain]. ”

“That’s the [Red Earth Continent].”

“It’s so big!!”

“It’s blocked by clouds, and I can’t see the edge.”

Everyone was sighing, Bai Yun felt the same way. He saw too many “big” things today, and his giant fear was so severe that he “died”.

“The entrance to the canal, I see it!”

Nami pointed to the entrance of the canal that climbed up the Upside-Down Mountain and shouted.

“It’s incredible...”

“The ocean is really...climbing the mountain...”

.......

This time, when climbing up the Upside-Down Mountain along the canal, the rudder of the Merry did not break.

Bai Yun thought, could it be that my luck of “bearing humiliation” and not swearing these days has worked?

After reaching the top of the mountain, I just need to let it rush down.

But the rudder was not broken, and Laboo was still blocking it.

Bai Yun noticed Laboo.

A sudden thought.

It can be said that everything that happened to the Straw Hat Pirates after entering the Grand Line was caused by Laboo.

If Laboo hadn't happened to block them, they wouldn't have met Weiwei and the others. If they hadn't met Weiwei, Luffy and the others might have chosen another magnetic line.

It was because of Laboo that the Straw Hat Pirates chose this path and met their current partners.

Before entering the New World, a group of whales on the seabed helped them determine the route.

Could it be that the whales are the guiding lights of the Straw Hat Pirates?
