"That is the beginning of the great voyage, which is called the Upside Down—the Incredible Mountain."

On the fifteenth day of the month, he pointed to the red earth continent looming in the storm not far away, and his face slightly revealed a look of nostalgia.

"About right in front of us, there will be a counter-current canal that leads to the top of the mountain. As long as we hang the sails and stabilize the rudder, its turbulent water will carry us all the way up! ”

"It sounds funny, but I can't imagine that one day I'll be able to climb a mountain by boat. Lafitte, I'll leave the direction to you, but don't let my "Rift" crash into the Red Earth. ”

Carlando first stared up at the red earth continent reaching into the sky, and then half-jokingly said to Lafitte, who was elegant and angry in front of the rudder.

"Yo hehehe, Chief, I'm guaranteed to give you a taste of the thrill of climbing the mountain."

Lafitte knew that there were still thirty ships waiting for the main ship to guide the way, so he naturally would not carelessly make an irreparable mistake.

"Boss! That's not right! ”

Traore, who had gone to the mountain pass to investigate the situation, quickly landed beside Carando, and said in a very anxious tone.

"I found the mountain pass, but the water of the canal did not swim against the current as rumored, but flowed down from the top of the mountain normally!"

"Huh?"

What's going on? Carlando was also stunned when he heard this, he couldn't understand how Upside Down Mountain was normal, and he knew that Traore wouldn't joke with him.

"It turns out that it's been a reflux period recently!"

After hearing Traore's words, the fifteenth of the month quickly recalled the information that Upside Down Mountain had become normal.

"Looks like we're going to need to stay here for three or five days."

"Reflux period? Stay for three or five days? ”

Finding out what he should know on the fifteenth of the month, Carlando directly asked about his doubts.

"The return period is the situation where the water flows from the great route to the four seas like it is now, and after about five days, it will return to normal."

Is this what I want to hear? Carlando was a little uncomfortable with the simple explanation of the fifteenth of the month.

"Is this the way back from the Great Voyage?"

"It's one of the ways to come back."

Seeing that Calando seemed to be very interested in this, Yue 15 thought about it and decided to explain it in detail.

"The most common way to return from the Great Voyage is to wait for the return of the Upside-Down Mountain.

The reflux period does not start at a fixed time, but occurs randomly throughout the year. So far, it has only been confirmed that there are four reflow periods per year, each lasting about five days.

To put it simply, there are only twenty days a year to travel from the Upside Down to the World. ”

Happens randomly? Four times a year? Five days at a time? Hearing this, Carlando raised his eyebrows, knowing that if he wanted to take advantage of the return period to rush back to the four seas, he could only spend time waiting near the initial island of the seven routes. Of course, if you're lucky, that's a different story.

"The second way is to walk the windless zone. It's just that compared to the less dangerous Upside-Down Mountain, where there is no wind to push the sails and a large number of sea kings gather, the mortality rate is extremely high. ”

Carlando is no stranger to this approach, after all, the easy and fast route of crossing the windless belt can be called the standard equipment of the most powerful people......

"The last way is to buy a cross-sea ticket for the king of the sea, Umit. Of course, if you can fly, you don't care about all three ways. ”

When talking about the last one, Yue Fifteen noticed that Traore was still in the form of a man and beast, so he added awkwardly.

"The cross-sea ticket of the sea king Umit?"

Knowing that this dark lord had a way to send people back from the Great Voyage, Carlando was naturally very interested.

Presumably, the master of Carlando also knows that the king of the sea also has a nickname, "deep current"! This deep current means that the king of the sea has a current located in the deep sea, which can reach the four seas directly from the great route. ”

That's how the nickname "Deep Current" came from. It's no wonder that Umet can sit in the position of the king of sea transportation, there is a cross-sea route that is close to monopoly, as long as it can be kept and not leaked to outsiders, the profits can be said to be rolling in!

"If I have the chance, I'd like to try this cross-sea route."

Umit has been able to do business across the sea for so long, and its method of secrecy must be leaky. But this deep current is so useful that Carlando naturally covets it.

……

Three days later.

With the strange change in the direction of the flow of the sea, Carrando and his party also understood that the return period should be over.

"Anchor, sail!"

After waiting for three days with curiosity, the people couldn't wait to go to the mountain pass after discovering that they could continue the voyage.

"Bang!"

With a sound from a long distance, everyone strangely found that the upside-down mountain in front of them was shaking.

"What's going on? Is the upside-down mountain in the earthquake? ”

"Oh no, stop!"

On the fifteenth day of the month, he suddenly remembered something and immediately asked Lafitte to stop sailing in horror. Lafitte looked at Carlando with some confusion, and only after seeing that his boss nodded, he asked the fleet to stop sailing.

"Bang!"

Not long after the flotilla stopped, another dull sound came from a distance.

"It's supposed to be the island whale hitting the mountain. I suddenly remembered that every time the reflux period ended, this big guy would definitely hit the mountain! ”

After hearing the voice again on the fifteenth day of the month, he was finally sure that he had not misremembered this incident.

"Island whales? Are you saying there's an island whale hitting the mountain across the side of Upside Down Mountain? ”

As a native of the West Sea, Lafitte naturally knows about the long-standing behemoth of the West Sea, the island whale!

"That's right! An adult island whale that doesn't know why it hit an upside-down mountain. ”

No one knows why this island whale hit the mountain, but as a behemoth, blocking the exit of the mountain often causes devastating blows to ships heading for the great voyage!

"Then it's time to stop......"

Once in the vicinity of the counter-current canal, it is impossible for the boat to stop, so it can only move forward. And when it comes down the mountain, under the acceleration of the current, the boat is afraid that it will crash into the island whale!

"How long does it usually hit?"

Callando also recalls that the island whale is called Rab, and that Brooke was once a companion of the Pirates.

"It won't last long, after all, it hurts a lot."

"Then wait."

This trip to the upside-down mountain was really bumpy! First there was the return period, and then the island whale blocked the way, and Carlando didn't know what to say.

"Bang!"

"Bang!"

"Bang!"

……

"Boss, that island whale should have been hit, and I didn't see it on the other side of the mountain."

Traore took a slight breath and reported to Carlando.

"That's good."

Looks like I need to keep exercising! Looking at Traore, who was a little out of breath when flying a mountain, how could Carlando feel safe to ride it...... Voyage.

Earlier, after discovering that there was no sound coming from and that the mountain was no longer shaking, the cautious Carlando sent Traore to investigate.

"Let's go."

As soon as these two events were messed up, Carlando's original anticipation suddenly dissipated, and he just wanted to pass the Upside Down Mountain smoothly.
