With that, Bill ignored Ian and gave the sailors the order to stay put, so the twelve ships dropped anchor and stayed where they were, waiting for Rab's voice to disappear.

Ian was listening intently, too, sighing at Captain Bill's folk wisdom.

He still remembered that Luffy had recklessly embarked on the great voyage without knowing anything, but when they went down the waterway, they happened to encounter Rab blocking the road, and finally they were about to collide, but Luffy fired the cannon at the bow to stop the ship.

Whether the reaction force of the cannon is so great, Ian didn't know, and at that time he was wondering, is it necessary for everyone who enters the great voyage to fire like this?

However, after coming to this real pirate world, he realized that he had thought about it, not everyone was a daredevil, not everyone was a daredevil, Rab's whale had been watching at Twin Cape for decades, and if every ship hit it, Twin Cape would have been clogged with the wreckage of the ship, and those who want to enter the great voyage always have their way.

Rab's cry was faint in the wind, and I don't know how long it took, Ian suddenly heard a roaring sound, and there was a tremor from the upside-down mountain in the distance, so Ian knew that Rab had begun to collide.

The fleet waited quietly, but fortunately, it didn't take long for Rab to actually hit the mountain, and when the tremor of the upside-down mountain stopped, Bill listened attentively again, and found that Rab's cry had indeed disappeared, so he immediately gave an order: "Everyone has it!" Weigh! Sail! ”

Bill, on the other hand, stood back at the bow of the ship, holding a telescope and began to look at the sea.

"What is this doing?" Ian asked behind him.

Without looking back, Bill explained, "Oh, I'm observing the ocean currents, and if you want to enter Upside Down Mountain, you have to follow the currents. ”

As soon as he finished speaking, Bill had already found the location of the current, so he turned his head and shouted, "Turn the rudder!" Head in the direction of two o'clock. ”

With Ian and their ship at the head, the rest of the ships in the rear also began to adjust their course, and the entire fleet began to slowly cut into the current.

Staying on the boat, Ian's feeling is the most obvious, when the ship enters the current, Ian only feels that the speed of the ship suddenly accelerates, just like the sudden acceleration of the car has the feeling of pushing back, Ian also feels the power brought by the acceleration of the ship, but at this time all the boats did not open their sails, and they were completely moving along the current.

"The water is so fast!?" Ian had a bad feeling.

When Bill heard his words, he didn't look back, continued to hold the telescope and look ahead, and said, "Of course, in such a current speed, it is difficult for the ship to adjust its direction, and the time to test us has come!" ”

Ian couldn't help licking his dry mouth, he thought that if he couldn't find a fleet, he would follow Ace's example and drive a small boat to the great voyage by himself, but now that he looks at it, he seems to be a little naïve.

"Right hand drive! 13 degrees! ”

"Many! Left rudder! 3 degrees! ”

"Good, keep it!"

Bill's orders were conveyed from time to time, and the sailors in charge of the helm nervously followed Bill's orders, and Ian knew that Bill was adjusting the course of the ship, and the area of the ocean current was large, but the entrance channel of the Upside Down Mountain was not so large, so it was necessary to align with the location of the entrance.

As we get closer to the entrance, the speed of the ocean current becomes more and more turbulent, and the speed of the ship is significantly faster, in this case, any general direction of the rudder is looking for death, and it is very likely that the rudder wheel will be broken, so Bill's orders are to fine-tune the course little by little.

The figure of the terracotta continent also appeared in the eyes of everyone at this time, it was a majestic mountain range, at a glance, you couldn't see how high it was, and you couldn't see how long it was, like a horizon, just across the front of the ship.

Some of the sailors on board, who were probably heading to the Great Voyage for the first time, were devastated at the sight of such a behemoth in front of them, and at the thought that if the ship had misoperated, they would have been destroyed and buried at the bottom of the sea, and they cried out in panic: "Turn back!" Back! We'll bump into it! ”

"Ian, shut them up!" Bill didn't look back at the tunnel.

Ian was also decisive, and immediately rushed over and slammed it on everyone's heads, knocking these panicked people to the ground.

Anyone with a little sailing experience knows that panic at this time will not do any good, it is all people in the same boat, they can only trust the captain's decision.

It was at this moment that Ian understood why the captain of a ship had such authority.

It could be seen that Bill was also nervous, sweat broke out on his forehead, although he had been on the Great Voyage more than ten times, he did not dare to guarantee that he was so lucky every time.

Outside the side of the ship, there are surging waves, the speed of the ship follows the current, reaching its peak at this moment, Ian looked towards the sea to the south, he knows that in fact, all the way to the south, you can reach the windless zone of the great route, as long as you pass through the windless zone, it is the great route, obviously it looks very simple, but no one chooses to take such a route, but chooses to take the entrance of the upside-down mountain, which shows that the windless zone is more dangerous.

In the hazy mist, the entrance can already be seen, in Ian's opinion, the course of their ship can enter the entrance smoothly, but Bill still did not relax, before entering the entrance, any sloppiness may cause irreparable consequences, so his orders are still being issued, constantly fine-tuning the ship's course.

Bang! With the sound of water crashing against the shore, the ship that Ian was on suddenly tilted up, and the whole ship became tilted, and everyone stood unsteadily, turning into a rolling gourd and falling on the deck.

However, even if it fell like this, it still couldn't stop the sailors on the ship from bursting into cheers!

"Long live Captain Bill!"

"Came in, we came in without a hitch!"

The reason why the ship was raised was because they had entered the waterway and were climbing the mountain along the waterway, and Bill was worthy of being an experienced old captain, and his adjustment of course allowed the ship to enter the channel accurately, and at this moment, he was the hero of the whole ship.

Bill also breathed a sigh of relief, turned his head to look at Ian and said, "Haha, sure enough, God also plans to let me retire smoothly!" ”

Ian smiled at him, and finally put his heart down.

"How's the boat in the back!?" Bill asked aloud.

A sailor in the stern, who was now looking behind with a telescope, also replied loudly: "Ship No. 2 enters...... Ship No. 3 also entered...... Number Four ...... Not good! The course of the ship number four has deviated! ”

As the sailors watched the shouts, many people ran to the stern of the ship with concern, and Ian followed suit, and he saw two ships behind him, both separated by a certain distance from each other, which were the second and third boats, and they both entered the channel smoothly, but at the entrance position, the fourth ship could see a clear deviation from the course!

He snatched the binoculars in the hands of a sailor and looked over, only to see that the people on the No. 4 ship were already in a mess at this time, and there were several people at the helm who were working together to knock the steering wheel over, but the speed of the ocean current was too fast, and the huge force brought by them, no matter how hard they tried, the ship was still deviating a little bit.

Then, suddenly, the group of sailors who wrenched the steering wheel fell to the ground at once.

"Not good! Their steering wheel is broken! A sailor, who was also watching, exclaimed.

"They're dead!" When Bill heard this, he couldn't help but feel sorry.

In Ian's sight, the fourth ship was carried by the current, and at a very fast speed, it crashed headlong into the mountain wall next to the entrance channel, and the entire ship disintegrated into countless pieces under the huge impact force.

The sailors on board were thrown into the air, then fell into the sea, and after sinking, they never came back again, not only people, but also the wreckage of the ship.

"They were swept away by the currents!" Bill took off his captain's hat and placed it on his chest in silence, saying, "May they rest in peace at the bottom of the sea." ”

None of the people in the boatload spoke, not even Ian, who took off their hats in greeting.

I heard that the great voyage was dangerous, but he didn't feel much, after all, he just listened to what others were saying, and he hadn't experienced it himself, but now he witnessed the destruction of the fourth ship, Ian now only feels that the whole person is not good, a ship, one or two hundred people, just because of a shipwreck, all of them were buried at the bottom of the sea!?

After the ocean current hits the mountain wall, it will form a downward rolling current, in this case, even people with good water nature can't float up, they can only turn into corpses and sink forever under the dark and cold seabed, such a shipwreck can be said to be shocking, but Bill and the other people on the ship have a commonplace expression, it seems that for them, they have seen this kind of thing more than once or twice?

"What should I do if the fleet is lost?" Ian asked Bill.

"What else can I do?" Bill shrugged and said, "Everyone who got on the boat was actually mentally prepared to die, and after losing one ship, we still have eleven ships, and we have to move on." ”

Even Ian didn't know how to say it now, but sure enough, he still didn't know much......

Perhaps because of the tragedy of the No. 4 ship, the ships behind became more and more cautious, and they adjusted their course with 120,000 spirits, and entered the channel one after another, and there was no loss again.

The only one who was killed was the No. 4 ship, and Ian shuddered and thought, "The No. 4 ship, what a miserable death!" In the future, I will not take a ship with such a mark if I kill myself! ”

Watching the boats climb the mountain along the waterway, Ian asked Bill, "How high is this mountain?" How long are we going to climb? ”

"It's usually about three minutes!" Bill took his pipe in his mouth and said, "Soon, when you reach the top of the mountain, you will be able to see the waterways of the other three oceans, eastern blue, western blue, northern blue and southern blue, and the currents of these four oceans will converge on the top of the upside-down mountain." ”

Can you see other oceanic waterways? Ian was stunned for a moment, and suddenly asked, "Uncle Bill, in this case, if there are ships in other oceans that happen to turn the mountain upside down along the waterway, won't they collide on the top of the mountain at that time?" ”

"Something like this has happened!" Bill smiled, "But the odds are very small, and you don't necessarily have to meet them once in a few years." ”

"What if it does?" Ian asked.

"Then it's just a matter of who survives!" Bill shrugged and smiled, "Don't worry, we don't have to be that unlucky." ”

However, before the words fell, the lookout on the mast suddenly shouted in panic: "Other ships have been found!" It's the South China Sea Channel! We...... We'll bump into them! ”

Bearden was dumbfounded, staring blankly at Ian.

Ian also wanted to give himself a slap: "Nima, call you crow's mouth!" ”
