This shaking made Dongfang Yue step on the air, and did not step on the pedal of the next gangway as he wished, but slipped and fell directly, fortunately he reacted quickly, and clamped the handrail with his arms, and finally did not get stuck, good guy, his reputation for decades was almost swept away, and he secretly laughed at himself.

As an old captain, this time he had to find out the reason, so Dongfang Yue walked to the side of the ship to probe out, the black blue sea surface that greeted his eyes was as calm as before, the green light on the starboard side was obliquely shining on the sea, and the white bow with a slight blue-green wave swept across the side of the ship and drifted towards the stern or further away, which seemed unusually quiet and ordinary; although the sound of the engine and the roar of the wind turbine were loud, they were also normal rumbles, and there was no abnormal sound; could it be that he was hallucinating? He knew that it was impossible, unless there was an undercurrent on the bottom of the sea that hit the hull of the ship, which could not be detected with the naked eye, and could only be ascertained through the comprehensive judgment of some nautical instruments and nautical data.

Could it be that the iron anchor at the bow of the ship was not fixed properly, and the swing hit the bow of the ship, causing the hull to shake? Dongfang Yue decided to climb back onto the bridge and go to the foredeck to take a look.

(Here it is necessary to introduce the specific situation of the Lisha medium-sized cargo ship, there may be some technical terms that are not easy to understand, it doesn't matter, everyone just takes it as a kind of common sense to understand and understand, and it does not affect the reading of the whole book.) The Lisha is 157 meters long, 20 meters wide, with a full load displacement of more than 9,000 tons, a draft of 5.8-6.0 meters, and a dumbbell-shaped hull, that is, about 20 meters at the bow is the foredeck, about 100 meters in the middle is the container deck, and 50-60 meters in the rear is the superstructure, wheelhouse, The aft deck, the front and rear decks are connected by the bridge, the bridge is about 100 meters long and 2 meters wide, the floor is made of iron mesh paved aluminum plates, there are railings on both sides about 1.2 meters high, there is a gangway in the middle of the bridge to get on and off the container deck, the foremast and windlass are on the foredeck, the crew driving and accommodation and power plant, The navigation devices are located in the rear section, and the red and green portholeways are also located on both sides of the rear section, if you still do not have an intuitive concept, you might as well go to the pier to see similar objects; because this is a book, most of the text comes from imagination, so in the follow-up description, try not to appear too obscure professional terms, but use some oral language, easy to read, if there are book friends working on the ship, please understand in the spare time)

Dongfang Yue lit up the strong flashlight and walked along the bridge to the front deck, the sudden shaking of the hull was only twice, so although the freighter was sailing at high speed at sea, the hull almost did not sway, and in about seven or eight minutes, he had already reached the front deck, and at this time there was already a black figure of medium stature standing on the deck, looking at the bow of the ship with full attention, and it seemed that he was throwing something into the sea in his hand.

Dongfang Yue coughed lightly, to be honest, this back is too familiar, at a glance, you can know that it is the guy who is chattering with gods - first mate Lu Jiawei, did he start sacrificing to the sea without asking for instructions this time? Unlike his style, Lu Jiawei often said that the sea sacrifice must be presided over by the captain to be effective, and he was really sulking today?

When Lu Jiawei heard the sound, he turned back in a panic, he was indeed taken aback, Dongfang Yue's footsteps were silent, like a ghost.

"Uh...... Captain, why are you here?" he muttered.

Dongfang Yue was suspicious in his heart: "What are you doing, what are you throwing into the sea?" his tone unconsciously carried some emotions and suspicions.

Lu Jiawei could naturally hear it, but he didn't answer immediately, but slowly sat on the bollard on the side of the gunwale, his eyes glazed and thoughtful.

This caused Dongfang Yue's unhappiness even more, and the first mate did not care about the operation of the ship, but ran to the front deck to reflect on life.

"Did you feel the hull of the ship vibrate just now? What is the reason......" Dongfang Yue went straight in, he suspected that this old guy had done something.

"It's not an anchor. Lu Jiawei finally spoke, "At first, I thought it was an anchor tripping...... Come and see, okay. Besides, the sea conditions are so good now that even if the anchor is disengaged, it will not hit the hull. He still didn't explain why he came to the front deck, and the shaking obviously happened after Lu Jiawei's arrival, because Dongfang Yue also came from the back to the front.

Lu Jiawei's expression was very complicated, looking a little blank, a little confused, and a little fearful mixed in.

"Perhaps...... Perhaps......" His voice was very low, and it drifted away without a trace with the wind blowing from the bow of the ship, and Dongfang Yue didn't hear what he was saying at all.

So Dongfang Yue just said coldly: "Go back, it's windy, don't come to the bow at night, no matter how good the sea conditions are, it's also a little dangerous...... You see you don't even have a life jacket on, really. He thought that Lu Jiawei would definitely not listen to him, so he took off the life jacket he was wearing and threw it on the windlass.

For the old-timers, I don't like it, but as a captain, he must be considerate of his crew, and for months, there is always some emotion in the wind and rain.

Dongfang Yue didn't say anything more, he turned on his flashlight again, and was about to turn around and return to the back section.

A hand suddenly grabbed his left arm, startling him.

Lu Jiawei took Dongfang Yue's hand for the first time, and his eyes showed an urgent desire to come.

"Dongfang, listen to me once, let's hurry up and sacrifice to the sea, okay?"

Dongfang Yue felt furious, this superstitious old guy was not qualified to be the first mate, but he just stared at Lu Jiawei coldly, without saying a word, intending to kill this annoying guy with his eyes.

Lu Jiawei was unconscious, he lowered his head as if he was thinking about something important, and he wanted to speak several times, and finally-

"Dongfang, you can believe me once. Martial arts," he still said, "I've been in this vast ocean, and I've been suffering for most of my life. Am I really that superstitious, you say?...... No, some things can't be explained, really can't be said, this is the Devil's Triangle, you won't know ......"

Dongfang Yue couldn't help but interrupt him: "How do you know that this is the Devil's Triangle, have you been here? What are the coordinates here, don't you know that we are on this route every time? The water is thousands of meters deep, and there are no shoals and reefs, what danger can there be......" He vented his dissatisfaction like a cannon.

"It has nothing to do with the coordinates or anything, no one knows the specific geographical location of the Devil's Triangle......"

Dongfang Yue waved his hand impatiently and shook Lu Jiawei's hand away, but he didn't turn around and leave, but said, "Since you know what's going on, why are you still squatting here?"

"I've had a very bad feeling these days, and I always feel that something is wrong with this voyage,...... But I can't tell what went wrong. Lu Jiawei said to himself, as if Dongfang Yue was not real, "I was upset just now, and I remembered a little, and unconsciously walked to the foredeck, and then I felt the hull shake violently twice, as if it had collided with something, but no matter how I observed, I couldn't find the reason for the shaking." I've been at sea for more than 30 years, and this is the first time I've encountered a strange phenomenon...... In the East, sailing on the vast oceans, sometimes we cannot be overconfident. ”

Unexpectedly, Dongfang Yue didn't refute him this time, he was actually a little puzzled about what caused the shaking just now.

"I think it's an undercurrent...... There are various thermoclines in the deep-water ocean, and the ocean currents are also very unstable, and some ocean currents are still relatively fast, so it is entirely possible that the course of our ship and the direction of the current produce an angle of attack, so it will suddenly shake, you see that there is no problem at all now, it is probably the same as I thought, otherwise, according to the degree of vibration just now, the hull may have been damaged. He said it more professionally, but Lu Jiawei was naturally able to understand.

"I understand that. Lu Jiawei nodded, "It's true that this possibility can't be ruled out, but it can't also rule out other possibilities, right?"

Dongfang Yue glanced at him narrowly, and said with a strange smile: "Other possibilities?" For example?...... Is there a monster in the sea?" he couldn't laugh or cry, this old guy wouldn't really believe this.

"You kid knows how to play tricks on my old man, don't you? What kind of monster ......" Although Lu Jiawei's face was heavy, he couldn't help but be amused, "It's Ultraman." Monsters are certainly impossible, but the possibility of undercurrents is not very large, the current data of this sea area is very clear, the maximum current speed will not exceed 3.5 knots, and the speed of our ship is 13 knots, even if it is a frontal impact, it will not cause any shock. ”

"Such ancient data, and not big data statistics, who knows how much hydrometeorological changes have passed over the years, maybe the ocean current here has increased to 13 knots......? Besides, do you see any ships that have done any professional surveys here? I haven't heard of it, this Section 3.5 is pure speculation. "Dongfang Yue is now discussing navigation with the eldest and first mate, and he has nothing to do, so he has to convince this old stubborn today.

"This is exactly what I can't figure out, you say, our Lisha has sailed on this route more than a hundred times, why have we never encountered such an undercurrent?...... Just now I tried to take a water mound (a tool to measure the depth of the water, the speed of the voyage, and judge whether to go anchoring, in fact, it is a few pounds of lead with a rope tied to it for hundreds of meters) and tried it, 10 meters to 20 meters of water depth, the undercurrent speed is very small. Dongfang Yue didn't expect Lu Jiawei to be measuring with a professional tool, and thought that he was hiding from himself to sacrifice to the sea, and he also felt a little guilty in his heart, so his expression slowed down a little.

"And what do you mean, don't beat around the bush......" he frowned slightly.

Lu Jiawei had probably been thinking about it for a long time, so he said unhurriedly: "Maybe there is a deep-sea whirlpool in this sea area." ”

Although his voice is still low, "deep sea whirlpool" These four words still really surprised Dongfang Yue, you may not know very well, the deep-sea whirlpool is not like our common spiral vortex in the small river and creek, that is not too powerful, and there is no threat to ships like Lisha, but the deep-sea whirlpool is different, its rotation radius is very large, the surface flow speed is not fast, it can completely swallow tens of thousands of tons of ships, drag to the bottom of the sea; Lisha is less than 10,000 tons, if it really encounters a deep-sea whirlpool, it will be extremely dangerous.

Thinking of this, Dongfang Yue couldn't help but break out a few drops of cold sweat on his forehead, he was not afraid of ten thousand in case, and his face also looked solemn. The two men standing on the foredeck now are long-time veterans, both of whom have a wealth of seafaring knowledge, and it would be impossible to get emotional when they really discuss these issues.

"Old Lu, do you think this is very likely?" he asked the old-timer quite modestly, completely different from his usual attitude.

Lu Jiawei didn't feel that his tone was abnormal, but seriously stretched out his left hand, roughly estimated the wind speed, and then said, "It's not completely impossible." His tone was flat, and he wasn't sure what he was saying, but it was powerful enough.

Dongfang Yue Qi said: "We have walked this route no less than 100 times, not to mention for the time being, this is also an international recommended route, the navigation method of the whole route is mature, the navigation aid facilities are also very complete, the chart information is also very detailed, hundreds of years of navigation records have never appeared in the phenomenon of deep-sea whirlpools, why is there such a sign suddenly today?......" he said while thinking.

"Could it be ?——" Dongfang Yue is a young man, so his ideas have always been more bold and unconventional.

He looked at Lu Jiawei, and seemed to read the same message in the eyes of the old seaman.

The hearts of the two men trembled at the same time.

--------------------------------------------------------------------

In the wheelhouse, the second officer Xia Yuanshen was organizing the personnel to sail normally, everything seemed calm, various navigation instruments were constantly jumping data, and several officers on duty were also sitting peacefully at their posts.

When Dongfang Yue and Lu Jiawei walked into the wheelhouse, the room was pitch black, which was the light control required by the night flight; the two cats went to the chart room, gently unscrewed the chandelier switch, and adjusted the light to just enough brightness to see the chart.

They leaned over to look for something on the chart, which was densely marked with various continents, islands, straits, waterways, and navigational aid signs, and the depth of water in the contour line was also covered with the entire chart.

Suddenly—

Lu Jiawei pointed to a place on the chart and exclaimed.

Dongfang Yue's expression became more solemn, he leaned over to take a closer look, there was a small flow circle in the place Lu Jiawei pointed, and one of the arrows with feathers was very conspicuously marked with numbers and letters: 10Kn, the two looked at each other, and there was indeed a place in the vast sea where the undercurrent speed reached 10 knots, but this place was 108,000 miles away from the route sailed by the Lisha? What is going on.

Lu Jiawei said in a low voice: "Either the global warming in recent years and the strengthening of ocean currents have caused the flow speed on this route to increase dramatically, or ......" He paused and looked at Dongfang Yue.

Dongfang Yue nodded, and said in a deep voice: "Either we seriously deviate from the scheduled route!"

He pondered for a moment and asked, "How many days have we been sailing on this course?"

Lu Jiawei thought for a while: "It's been more than half a month...... If the course deviates greatly, we are more than 5,000 nautical miles away from the intended course. (More than 5,000 nautical miles is nearly 10,000 kilometers)

The two of them looked suspicious, and they naturally knew that all the nautical instruments and positioning devices were displayed very normal, including the electronic charts relying on satellite positioning, showing that the current position of the Lisha was in the center of the route, and it was only slightly reasonable to deviate.

Could it be that the ghosts of the sea hit the wall?
