Ranfang Island beach in the early morning, white sand and blue sea, blue sky. In terms of scenery, it is really not inferior to Bali and Semporna.

It's just that for people who have lived here all their lives, the most important thing is to survive in front of them, and they really don't have the leisure to enjoy this commonplace beauty.

Gu Kun took a few deep breaths of the salty sea breeze, and after confirming the sea conditions, he decided to do some restorative adaptation first.

After all, this is the first time he has gone to sea since he was reborn, and he is not very comfortable with this young body, so it is better to be safe.

Lowering the sails of the boat more than a mile offshore, Gu Kun put on frog flippers and breathing apparatus, and plunged into the sea with a fish leap.

As soon as he entered the water, he felt something strange.

"How did my hearing become so sensitive?"

He was a little scared, closed his eyes and felt with his heart, it seemed that a large number of fish and whale sharks within ten nautical miles could be heard clearly, and the sense of direction was accurate, it was simply a sonar built into his ears.

However, once out of the sea and back on board, this auditory anomaly is less noticeable.

Could it be that he had been gelding, an Arleigh Burke-level sonar before he was reborn, which caused him to have some indescribable mutations?

That's the latest high-precision passive sonar in 2019, 25 years ahead of the most advanced sonar on the planet in '94.

In any case, the poor rely on mutation, as long as there are no side effects, it is always a good thing.

After accepting this setting, Gu Kun familiarized himself with the water again with great anticipation.

This attempt was even more incredible, and he found that he was simply talented.

He first tried to hold his breath underwater in a relaxed state.

As a result, when he couldn't hold it anymore and floated up, it had been half an hour since he looked at his watch. The original world record of static breath-holding for earthlings was only 22 minutes.

After measuring the lung capacity, the next step is to swim at various speeds.

Gu Kun pinched the watch and estimated that after putting on flippers and respirators, he could sprint at full speed, and he could swim at about 15 knots against the sky!

The earthling's instrumental swimming world record was originally only 8.5 sections.

As for the races without equipment, there is no comparison, for example, the Olympic freestyle sprint record is only about 5 knots.

As a result, his swimming ability surpassed the world record by 70%, reaching half that of dolphins. After all, he is still a human being, and he can't violate the laws of physics.

After getting familiar with these mutations, Gu Kun's mentality quickly calmed down, and he didn't expect too much, just as the icing on the cake.

The gentleman's nature is not different, and he is good at faking things.

If you want to be a man as powerful as One Piece, after all, you rely on IQ and strategy, not force value and "domineering".

After confirming that he was in perfect condition, Gu Kun sailed due west and officially set sail.

......

The sixth-level sea breeze was not too big, but Gu Kun's ship was too small, so other sailors really didn't dare to sail out alone.

The magnitude of the wind and waves is always a relative value. If you drive a 10,000-ton ship, you can easily sail with a force 10 wind. The thousand-ton wheel can easily carry up to level eight.

As for small boats of several tens of tons, a wind of level 6 can make the waves higher than the boat.

When sailing in troughs, it is common to see the left and right waves passing over the cabin roof.

Gu Kun was like a person who had nothing to do, not only walking on the ground, but even daring to turn off the diesel engine and raise the sails to sail.

The six-level tailwind is enough for the fishing boat to sail at a full sail speed without power, and it also saves fuel.

The only downside to the sail condition is that the longitudinal torque of the boat will be greater, and it will be more bumpy when crossing crests and troughs.

It's a pity that for Gu Kun, bumps are not a problem.

I saw that his body could swing with the wind very naturally, and he had a strong sense of balance. Even if the ship tilted 40 degrees, he stood firmly, walking around the deck like a leisurely stroll.

He wears no shoes, and can hold the deck with his five toes open, just as an ape's feet can grasp a twig.

In fact, this is not unusual, many old captains who have experienced decades of strong winds and waves will practice this skill.

Let the wind come harder.

Because of the smooth wind, by evening, Gu Kun had already driven out more than 100 nautical miles, bypassing the northwestern corner of Borneo and entering the Java Sea.

There are less than 30 nautical miles to go to the final intended destination. But considering that the night was not suitable for work, Gu Kun chose to find a cape shoal to go down, and then cooked a big pot of food on the boat himself, and slept beautifully in a hammock all night.

Maintain enough physical strength to dive the next day.

As for the content of the dinner, there is nothing to go into detail.

It's nothing more than picking out five or six catties from the various miscellaneous fish that I dragged to today, and after simply cleaning and removing the internal organs, I added two catties of fragrant rice and a few lemongrass to cook together. Eating a few bananas after a meal is considered a dessert and a vitamin supplement.

People who run the sea have a large amount of food, because they usually only eat two meals a day, and they also stop the boat and go down to eat again, so as not to feel uncomfortable because the boat is too bumpy after eating.

And Gu Kun felt that after he was reborn, not only did his water and hearing become stronger, but even his calorie consumption rate was several times faster than that of a normal person.

He has eaten so violently in the past two days, and the fat of his whole body is still declining at a rate that is visible to the naked eye. The muscles are not small, but the blood vessels under the skin are visible.

It seems that in the future, we will not only eat fish, rice, and fruits every day, but also eat more alcohol, meat, and chocolate.

......

When I woke up the next day, I was in a very good state of mind and the wind was lighter, only three or four levels, which was very suitable for diving operations.

Gu Kun didn't say a word, and was ready to work.

First, he measured his current position.

Then take out the coordinates that were hastily marked on the chart according to memory before departure.

These coordinates are all Gu Kun's later generations from the documents that have been decrypted, after realizing that he was reborn the day before yesterday, he took out a small notebook as soon as he got home, and quickly recorded the data he remembered.

A good memory is better than a bad pen.

In fact, the part that Gu Kun could remember only accounted for less than half of the total amount of data he had seen in his previous life.

After all, no one expected that they would be reborn and prepared in advance.

So now I can only remember what to catch, and I don't have to be picky.

"The nearest hydrophony station should be in the trough between Yamaguchi and the island of Benua, 17 nautical miles east and 2.5 nautical miles south. My current position is directly north of Yamaguchi Yanggang, 27 nautical miles away in a straight line, and the economic speed will be two and a half hours. ”

Gu Kun muttered to himself, then wrenched the anchor, started the diesel engine, adjusted the course and went straight away.

If you drive a boat alone at sea for a long time, you will inevitably be nervous because of boredom. Therefore, old sailors are accustomed to talking about their thoughts to create some social illusions.

Look at Hemingway's "The Old Man and the Sea", and you know that they can beep for a long time when they catch a fish.

Hemingway is the most concise writer in his writing style, so the people who are annoyed by Hemingway must be really annoying.

Two and a half hours later, the sailboat stopped at Target Point No. 1.

Gu Kun dropped anchor and turned off the fire, changed into a diving suit, oxygen cylinders, flippers, and diving flashlights, and went down to explore the way first.

It felt good to enter the water, and his hearing abilities were starting to work again.

Whales and boats within a few nautical miles can determine the direction of any target that is more than 5 meters long.

For targets within a few hundred meters, the listening accuracy is even higher. Basically, even animals about 1 meter tall such as dolphins and tuna can be heard.

After concentrating and feeling it for a while, Gu Kun quickly discovered the target location.

Five or six hundred meters to the northeast of him, there was a metal pontoon held by heavy anchors, which swung back and forth in the trough with the current, making an echo in the air, at a depth of about 80 meters.

For a normal person, a diving depth of 80 meters is very dangerous, but Gu Kun is obviously not a normal person. When he set sail the day before yesterday, he originally wanted to test his diving ability, but unfortunately the water was too shallow at that time, and now he is using this to practice his hands.

The unarmed diving record of earthlings is 120 meters, and the record can reach 330 meters in pressurized suits. Gu Kun felt that 80 meters was not difficult for him.

He swam over slowly, quickly dived to the specified depth under his own strength, and then turned on the diving flashlight to observe it closely, and sure enough, it was a cylinder several meters long, with hemispherical ends at both ends.

Gu To, who is a human being in two lives, is very familiar with this thing.

There are generally two types of things: large and small. The small ones were lost by anti-submarine aircraft, about the same size as bazookas, the detection range was close, and they were disposable, often fixed with buoys floating on the water.

The big one is the guy in front of him, at first glance, it was lost by a warship, the barrel body weighs hundreds of kilograms, and the bottom is anchored with a sinking weight, the detection range can be dozens or even hundreds of nautical miles, it can be used for many years, and it can be sold for a lot of money if it picks up garbage.

The most common way to get this big guy away is to hang it away with the anchor counterweight below. Gu Kun did this when he had a big ship in his previous life.

But now his boat is too small to break the metal cables and take the sonar alone.

Gu Kun tried, but it was just an ordinary stranded wire rope, and it was not as thick as the lock strip of the battery car. And after soaking in the sea for three or five years, even the nickel-chromium steel is a little rusty.

He came prepared, took out the hydraulic pliers on his back, cut them a few times, and broke several bundles of steel wires, and estimated that there were still a few square millimeters of cross-sectional area left, so he stopped.

Then he quickly surfaced, returned to the boat, pulled the rope of the trawl, returned to the position just now, wrapped the pontoon with the trawl, and prepared to drive the boat and pull hard.

Normal deep-water diving is about going fast and slow. Because if the pressure drops too quickly, it will lead to the precipitation of dissolved oxygen in the blood vessels and the formation of bubbles, which is oxygen poisoning, which is very dangerous.

However, there are exceptions, that is, if the total time of launching is less than 20 minutes, you can get off and on quickly. Because in such a short period of time, the blood vessels have not yet adapted to the deep water high pressure, and at this time, the pressure is immediately reduced, and there is no problem of oxygen precipitation.

Gu Kun is obviously in the latter situation, because he swims quickly and has a perverted physique, from diving to find and even the operation belt to float, it all adds up to less than twenty minutes.

And the reason why he didn't cut the cable directly just now was also deliberate.

Because he hopes that when the shipment is made, the buyer can see that the wire rope of the sonar pontoon is in a torn state, so that it can be interpreted as "the trawl was accidentally entangled during fishing".

If the fracture is very neat, and it looks like it was cut by hydraulic tongs, then it will be a goof, and others will suspect that you have been planning for a long time.

The second reason is that it is too dangerous to cut it directly - you can imagine how painful it is for a stiff bow to be fully drawn, and the bowstring is suddenly cut, and it bounces on the archer.

The wire rope with the thickness of the little finger is thrown out instantly when it breaks, and it can easily bounce a diver to death.

Fortunately, as a veteran driver with more than 20 years of experience, Gu Kun easily turned the above risks into invisible.

If you change to a diver who has no ability, just a moment ago, you have already lost two lives.

Yesterday, I found an editor to sign and apply for the completion of the old book.

But yesterday the editor was not there for a day, and I couldn't find it. So the pace of signing may be a day or two slower.

I can only make one change on Saturdays and Sundays, and I will guarantee two changes and 6,000 words a day from next Monday.
