In the early morning, Lanfang Island Beach has white sand, blue sea, and clear blue sky. In terms of scenery, it is indeed not inferior to Bali and Semporna.

However, for people who have lived here all their lives, survival is the most important thing in front of them, and they really don't have the leisure to appreciate such commonplace beauty.

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

After all, this was the first time he went to sea after his rebirth, and he was not very accustomed to his young body, so it was better to play it safe.

After lowering the sails and anchoring the boat more than a mile offshore, Gu Kun put on frog webs and a respirator and jumped into the sea.

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

"How did my hearing become so sensitive?"

He was a little scared, so he closed his eyes and felt it with his heart. It seemed that he could clearly hear the large schools of fish and whale sharks within ten nautical miles, and his sense of direction was extremely accurate. It was like having sonar built into his ears.

However, once you leave the sea and return to the boat, this auditory abnormality is not so obvious.

Could it be that he acquired an Arleigh Burke-class sonar before his rebirth, which caused him to undergo some indescribable mutation?

That is the latest high-precision passive sonar in 2019, which is 25 years ahead of the most advanced sonar on the planet in 1994.

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

After accepting this setting, Gu Kun became familiar with the water properties with great anticipation.

This test was even more incredible, and he discovered that he was simply gifted.

He first tried holding his breath underwater in a relaxed state.

As a result, when he couldn't hold on any longer and came up, he looked at his watch and found that half an hour had passed. The original world record for static breath-holding by people on earth was only 22 minutes.

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

Gu Kun checked his watch and estimated that after putting on his hand fins and respirator and sprinting at full speed, he could swim at an incredible speed of about 15 knots!

The world record for human swimming on Earth was originally only 85 knots.

As for competitions that do not use equipment, there is no comparison. For example, the Olympic freestyle sprint record is only about 5 knots.

Therefore, his swimming ability seems to exceed the world record by 70% and reach half of that of a dolphin. After all, he is still a human being and cannot 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. He just regarded it as the icing on the cake.

The nature of a gentleman is not different; he is kind and false in nature.

If you want to become a man as powerful as the Pirate King, you ultimately need to rely on IQ and strategy, rather than force value and "sense, knowledge, color and domineering".

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

The sea breeze at Level 6 is not too strong, but Gu Kun's boat is too small, so other sailors really don't dare to sail out alone.

The size of wind and waves has always been a relative value. If you drive a 10,000-ton ship, you can easily sail in strong winds of level 10. A 1,000-ton ship can easily sail in strong winds of level 8.

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

When sailing in a wave trough, you can often see waves on the left and right covering the cabin roof.

Gu Kun, on the other hand, acted like a normal person. Not only did he walk on flat ground, he even dared to turn off the diesel engine and raise the sail to sail.

A Category 6 tailwind is enough for a fishing boat to sail at a speed of more than ten knots without power and with full sail, while still saving fuel.

The only disadvantage of the sail state is that the longitudinal torque of the boat will be greater, and it will be more bumpy when crossing the peaks and troughs of the waves.

Unfortunately, for Gu Kun, bumps and bumps are nothing to worry about.

I saw that his body could sway with the wind very naturally, and he had a strong sense of balance. Even if the ship tilted 40 degrees, he could still stand firm, and walking around on the deck was like taking a leisurely stroll.

He doesn't wear shoes either, and his five toes can spread out to grip the deck, just like an ape's feet can grip tree branches.

In fact, this is nothing unusual. Many old captains who have experienced decades of strong winds and waves have developed this skill.

Let the wind blow more violently.

Due to favorable winds and smooth currents, by evening, Gu Kun had sailed more than a hundred nautical miles, bypassed the northwest corner of Borneo, and entered the Java Sea.

There were less than 30 nautical miles away from the final expected destination. However, considering that it was not suitable for work at night, Gu Kun chose to find a Cape and a shoal to anchorage, and then cooked a large pot of food on the boat and ate it in the hammock.

Had a good night's sleep.

You need to build up enough strength to do your full diving work the next day.

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

I just picked out five or six kilograms of various miscellaneous fish that I picked up today. After simply cleaning and removing the internal organs, I added two kilograms of fragrant rice and a few lemongrass and cooked them together. After the meal, I ate a few bananas as dessert.

Supplement vitamins.

People who go to sea usually eat a lot, because they usually only eat two meals a day, and they have to stop the boat and disembark before eating, so as not to feel uncomfortable after eating because the boat is too bumpy.

And Gu Kun felt that after his rebirth, not only did his water ability and hearing become stronger, but his calorie consumption was also several times faster than that of normal people.

He had eaten so hard in the past two days, and his body fat was still declining at a rate visible to the naked eye. His muscles were not small, but the blood vessels under the skin were visible.

It seems that from now on I can’t just eat fish, rice, and fruits every day, but also eat more meat, wine, and chocolate.

When I woke up the next day, I was in a very good state of mind. The wind was also lighter and only level 3 to level 4, which was very suitable for diving operations.

Gu Kun was ready to start without saying a word.

First, he measured his current position.

Then I took out the coordinates that I had jotted down on the chart from memory before setting off.

These coordinates were obtained by Gu Kun from decrypted documents in later generations. After he realized that he was reborn the day before yesterday, he immediately took out his small notebook when he got home and quickly recorded the data he still remembered.

A good memory is not as good as a bad pen.

In fact, the part that Gu Kun could remember only accounted for less than 20% of the total amount of data he had seen in his previous life.

After all, no one expected that they would be reborn, so they were always prepared in advance.

So now I can only catch what I remember, so I don’t have to be picky about food.

"The nearest hydrophone station should be 17 nautical miles due east of Singkawang Port and 2.5 nautical miles south of Singkawang Port, in the trough between it and Benua Island. My current location is offshore due north of Singkawang Port.

The straight-line distance is still 27 nautical miles, and we still need to drive at economic speed for two and a half hours."

Gu Kun recited it to himself, then winched the anchor, started the diesel engine, adjusted the course and headed straight away.

If you sail alone at sea for a long time, you will inevitably become neurotic due to boredom. Therefore, old sailors are used to talking to themselves about their inner thoughts to create some social illusions.

If you look at Hemingway's The Old Man and the Sea, you will know that they can beep for a long time even if they catch a fish.

Hemingway is considered to be the most concise writer in writing style, so the people Hemingway writes about are annoying, they must be really annoying.

Two and a half hours later, the motor boat stopped at target point No. 1.

Gu Kun lowered the anchor and turned off the engine, put on a diving suit, an oxygen bottle, flippers, and a diving flashlight, and went down to explore the route first.

It felt good to enter the water, and his auditory powers started to work again.

Whales, ships, and moving targets with a length of more than 5 meters within a few nautical miles nearby can all determine the direction.

For targets within a few hundred meters, the detection accuracy is even higher. Basically, even animals as small as 1 meter like dolphins or tuna can be heard.

After feeling it for a while, Gu Kun quickly found the target location.

Five or six hundred meters to the northeast, there was a metal buoy fixed by a heavy anchor, swinging back and forth along the ocean current in the ocean trough, emitting a hollow echo at a depth of about 80 meters.

For normal people, diving to a depth of 80 meters is very dangerous, but Gu Kun is obviously not a normal person. When he went sailing the day before yesterday, he originally wanted to test his diving ability, but unfortunately the water was too shallow at that time.

Practice this.

The diving record for people on earth without equipment is 120 meters, and the record for people wearing a pressurized suit can reach 330 meters. Gu Kun feels that 80 meters is no difficulty for him.

He slowly swam over and quickly dived to the designated depth under his own power. Then he turned on the diving flashlight and took a closer look. Sure enough, it was a cylinder several meters long with hemispherical ends at both ends.

Gu Wan, who has lived for two generations, is very familiar with this stuff.

This thing generally comes in two categories: small and large. The small one is thrown by an anti-submarine aircraft. It is about the same size as a rocket launcher, has a short detection range, and is disposable. It is often fixed with a buoy floating on the water.

The big one is the one in front of me. It looks like it was lost by a warship. The barrel weighs several hundred kilograms and is anchored with heavy objects that sink to the bottom. The detection range can be dozens or even hundreds of nautical miles. It can be used for many years.

Trash can also be sold for a lot of money.

To get rid of such a big thing, the most common way is to winch it away together with the anchor weight below. Gu Kun did this when he had a big ship in his previous life.

But now his boat is too small, so he can only break the metal cable and remove the sonar alone.

Gu Kun tried it, but it was just an ordinary stranded steel wire rope, not as thick as a battery car lock bar. Moreover, after being soaked in the sea for three to five years, even the nickel-chromium steel was somewhat rusted.

He came prepared, took out the hydraulic pliers on his back, cut several times, and broke several bundles of steel wires. He 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 up the trawl rope, returned to the previous position, wrapped the pontoon tightly with the trawl net, and prepared to launch the boat and pull it.

Normal deep-water diving emphasizes descending quickly and ascending slowly. If the pressure drops too quickly, dissolved oxygen in the blood vessels will precipitate and form bubbles. This is oxygen poisoning, which is very dangerous.

However, there are exceptions, that is, if the total duration of entering the water is less than 20 minutes, you can go down quickly and get up quickly. Because in such a short period of time, the blood vessels have not adapted to the high pressure of deep water, and then the pressure is immediately decompressed, so there is no oxygen release.

problem.

Gu Kun is obviously in the latter situation, because he is a fast swimmer and has abnormal physical fitness. From diving to searching to operating and resurfacing, it takes less than 20 minutes in total.

And the reason why he didn't cut the cable completely just now was also after careful consideration.

Because he hopes that when shipping, the buyer will see that the wire rope of the sonar buoy is in a torn state, so that it can be explained as "accidentally tangled in the trawl while fishing."

If the cut is neat and it looks like it was cut by hydraulic pliers, then it is a mistake and others will suspect that you have planned it for a long time.

The second reason is that it is too dangerous to cut it directly. Just imagine how painful it would be for the archer to feel the string of a fully drawn stiff bow being suddenly cut.

A steel wire rope as thick as a little finger can be thrown out instantly if it breaks, and can easily kill a diver.

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

If it were an incompetent diver who had done it, two lives would have been lost just now.

Yesterday I went to the editor to sign it and apply for a completed copy of an old book.

But the editor was away all day yesterday and couldn't find it. So the signing pace may be a day or two slower.
Chapter completed!
