After that, Bill ignored Ian and gave the sailors the order to stay in place, so the twelve ships dropped their anchors and stayed in place, waiting for Labu's voice to disappear.

Ian also listened carefully, while sighing about captain Bill's wisdom.

He still remembers that Luffy and his colleagues rashly set foot on the great route without knowing it. As a result, when they went down the waterway, they just met Labu blocking the road. At last, they saw that they were about to collide with each other. It was Luffy who fired the bow gun that stopped the ship.

Is the reaction force of the cannon so great? Ian didn't know. At that time, he was thinking, does everyone who enters the great route need to fire like this?

However, after he came to the real world of pirates, he realized that he was wrong. Not everyone was as reckless as Luffy. Labu's whale had been watching Gemini promontory for decades. If every ship hit it, Gemini promontory would have been blocked by the wreckage. People who want to enter the great route always have their way.

Labu's cry is faint in the wind. I don't know how long later, Ian suddenly hears a roaring sound, and the inverted mountain in the distance is shaking. So Ian knows that Labu has begun to bump.

The fleet waited quietly. Fortunately, it wasn't long before Labu really hit the mountain. When the tremor of reversing the mountain stopped, Bill listened and found that Labu's cry really disappeared. So he immediately gave the order: "everyone has it! weigh anchor! Set sail

Bill, on the other hand, stood in the bow again and began to observe the sea with a telescope.

"What are you doing?" Ian asked behind him.

Bill didn't look back and explained, "Oh, I'm observing the ocean current. If I want to enter the inverted mountain, I have to follow the ocean current."

As soon as he had finished, Bill had found the location of the current, so he turned his head and cried out, "turn the rudder! It's two o'clock. "

Yi'an and the others began to adjust their course, and the whole fleet began to slowly cut into the current.

Ian's feeling is most obvious when he stays on the boat. When the boat enters the ocean current, Ian only feels that the speed of the boat suddenly speeds up, just like a car suddenly speeds up and has the feeling of pushing its back. Ian also feels the power brought by the acceleration of the boat. However, at this time, all the boats do not open their sails and are moving along the ocean current.

"How fast is the current?" Ian has a bad feeling.

Bill heard what he said, but he didn't look back. He continued to look ahead with his telescope and said, "of course, it's very difficult for a ship to adjust its direction at such a speed. It's time to test us!"

Ian couldn't help licking his dry mouth. At first, he thought that if he couldn't find the fleet, he would learn from ace and drive a boat to the great route by himself. However, now he seems to be naive.

"Right rudder! 13 degrees! "

"Too much! Left rudder! Three degrees! "

"Good, hold on!"

Bill's orders are conveyed from time to time. The sailor in charge of steering is nervously and strictly carrying out bill's orders. Ian knows that bill is adjusting the course of the ship. The area of the ocean current is large, but the entrance channel of the upside down mountain is not so large, so he must aim at the entrance position.

As it gets closer and closer to the entrance, the speed of the ocean current becomes more and more turbulent, and the speed of the ship is obviously speeding up. In this case, any rudder in the general direction is looking for death, and it is likely to break the rudder wheel. Therefore, Bill's order is to fine tune the course bit by bit.

The figure of the red earth continent also appeared in people's eyes at this time. It was a towering mountain range. At a glance, you could not see how high or how long it was, just like a horizon, just across the front of the ship.

It may be the first time for some sailors on board to go to the great sea route. Seeing such a huge object lying in front of them, they thought that if the ship was misoperated, they would destroy the ship and bury people at the bottom of the sea. These sailors suddenly collapsed, and they cried in panic: "turn back! come back! We'll run into it

"Ian, shut them up!" Bill doesn't go back to the tunnel.

Ian also decisive, immediately rushed over, in each head hard for a while, will these panic people stun on the ground.

People with a little sailing experience know that panic at this time will not do any good. It's all people on the same ship. 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 can be seen that bill is also very nervous. Sweat comes out on his forehead. Although he has been traveling for more than ten times, he can't guarantee that he is so lucky every time.

Outside the side of the ship, there are sharp waves, and the speed of the ship reaches the peak with the current at this moment. Ian looks to the South Sea. He knows that he can reach the windless zone of the great route all the way south. As long as he passes through the windless zone again, it is the great route. It seems very simple, but no one chooses such a route, On the contrary, we choose to take the entrance of inverted mountain, which shows that the windless zone is more dangerous.

In the hazy fog, we can see the entrance. In Ian's opinion, the course of their ship can enter the entrance smoothly, but Bill is still not relaxed. Before entering the entrance, any carelessness may cause irreparable consequences, so his orders are constantly issued, constantly fine-tuning the ship's course.

Boom! With the sound of the current slapping on the coast, Ian and the boat they were on suddenly tilted up, and the whole boat became tilted. All of them could not stand still, and fell on the deck like a rolling gourd.

However, even if it fell like this, it still couldn't stop the sailors on board from cheering!

"Long live captain bill!"

"Come in, we come in smoothly!"

The reason why the ship is lifted up is that they have entered the waterway and are climbing along the waterway. Bill is an experienced captain. His adjustment of course makes the ship enter the waterway accurately. At this moment, he is the hero of the whole ship.

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

Ian smiles at him, and finally puts his heart down.

"What's the situation of the ships behind?" Asked Bill aloud.

A sailor at the stern of the ship, looking behind with a telescope, also replied loudly, "vessel 2 enters... Vessel 3 enters... Vessel 4... No good! The course of vessel four is off

With the shouts of the sailors, many people were concerned and ran to the stern. Ian also ran past. He saw two ships behind, which were separated by a certain distance. They were No.2 and No.3 ships. They all entered the channel smoothly, but at the entrance, No.4 ship could see the obvious course deviation!

He grabbed the telescope in the hand of a sailor and looked at it. He saw that the people on the fourth boat were already in a mess. There were several people working hard together at the rudder, trying to drive the steering wheel. However, the speed of the ocean current was too fast, which brought great power. No matter how hard they tried, the boat still deviated a little.

Then, the group of sailors who pulled the steering wheel suddenly fell to the ground.

"No! Their steering wheel is broken Exclaimed a sailor, who was also observing.

"They're dead!" When Bill heard this, he said with regret.

In Yi'an's sight, the No. 4 ship was carried by the current, and at a very fast speed, it collided with the mountain wall beside the entrance channel. Under the huge impact force, the whole ship disintegrated into countless pieces.

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

"They were carried away by the current!" Bill took off his captain's cap, put it on his chest and said, "may they rest at the bottom of the sea."

A boat of people did not speak, even Ian is also, have to take off their hats.

He didn't feel much when he heard that the great route was dangerous before. After all, he just heard what others were saying. He didn't experience it personally. Now he has witnessed the shipwreck of No. 4. Ian only thinks that the whole people are not good now. One ship, one or two hundred people, are all buried at the bottom of the sea because of a shipwreck!?

After the ocean current hits the mountain wall, it will form a downward rolling ocean current. Under such circumstances, even people with good water quality can not float up, they can only turn into corpses and sink under the dark and cold sea floor forever. Such a shipwreck can be said to be shocking, but Bill and other people on the ship all have a common expression. It seems that this kind of thing is very common to them, More than once, twice?

"The fleet has lost money. What should we do?" Ian asked Bill.

"What else can we do?" Bill shrugged and said, "everyone who gets on the boat is ready to die. One boat has been lost, and we still have eleven. We still have to move on."

Now even Ian doesn't know how to say it. Sure enough, he's less knowledgeable

Maybe it's because of the tragedy of the No.4 ship. The ships behind are more and more careful. They adjust their course with 120000 spirit and enter the channel one after another. There is no loss.

The only ship that was killed was No. 4. Ian shivered and thought, "No. 4, what a terrible death! In the future, I won't take a boat with such a label! "

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

"Usually about three minutes!" Bill held his pipe in his mouth and said, "soon, when you get to the top of the mountain, you will be able to see the watercourses of the other three oceans, Eastern blue, Western Blue, northern blue and southern blue. The ocean currents of these four oceans will all converge at the top of the inverted mountain."

Can you see the waterways of other oceans? Ian was stunned for a moment, and suddenly asked, "Uncle Bill, in this case, if there are ships in other oceans going up the waterway and overturning the mountain, won't they collide on the top of the mountain?"

"It did happen!" "Bill said with a smile:" but that kind of chance is very small. It doesn't happen once in a few years“ What if it happens? " Asked Ian“ Then we have to see who can survive! " Bill shrugged and said with a smile, "don't worry, we don't have to be so unlucky." However, before the words came to an end, the watchman on the mast suddenly cried out in alarm: "find other ships! It's the South China Sea channel! We'll... We'll run into them! " Bill looked at Ian stupidly. Ian also wants to give himself a slap: "NIMA, call you crow mouth!"
