"Occasional Roar~"

The sailboat was racing against the wind, and the water was rapidly retreating under the boat. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Sometimes the speed was so fast that the bow of the ship jumped half a foot high, and then fell heavily on the sea, splashing the sky and scattering in all directions.

Men mostly love the thrill of speed, and this is no different at sea.

Experience the thrill of unparalleled speed and excitement that will make you feel happy. He couldn't help but let out a strange cry in his mouth, and he sent a song, "Song to the sky".

At this time, there was a sudden "drop" in my ears, and the system prompt sounded after a long time.

Check it out, it turns out that [Navigation] has been upgraded to LV2.

With a lot of information coming back in his mind, he immediately felt like he had taken the maneuvering of the Whale to another level.

Grasping the mast in hand, one hand reaches into the sea to experience the temperature of the current, the boat is too fast, and the palm of the hand marks a long water mark on the water.

With a slight flick of the sail rope, the canvas instantly reverses its direction and keeps moving fast against the wind speed. "Experienced old fishermen will follow the currents. There was a slight difference in temperature in the water, and I only had to sail to one of the hotter currents to avoid losing my way. ”

"I believe you are no strangers to the sailing competition, which is a beautiful and challenging project, using a buoy to enclose a polygonal body of water on the sea surface, and the participating sailboats sail around the standard, and the wind force and direction on the sea surface are complex and changeable. In order to win against the clock, the players must always 'see the wind and steer'. ”

"Most people think that sailboats are pushed by the wind, and sailing downwind allows the boat to get the fastest speed. In fact, a sailboat that is completely downwind cannot achieve the best speed. ”

"Outsiders look at the bustle, insiders look at the doorway. ”

Chen Ergou said with a smile on his face: "Actually, there are two forms of force that the air acts on the sail: one is that when the air flows, it can have an impact on the object blocking the way. It is easy to understand that when a sailboat is sailing downwind, it is propelled by the dynamic force of the air. ”

"The other is that when the air velocity on both sides of the sail is different, there is a pressure difference. In fluid mechanics, this scientific principle is called Bernoulli's principle, which roughly means that the static pressure is lower at the higher the velocity of the gas, and the lower the velocity of the gas, the greater the static pressure......"

glanced sideways at the live broadcast room, and the barrage was full of an army of question marks.

“？？？”

"It's amazing, I just don't understand. ”

"If you don't agree with each other, you will pretend to be forced, fluid mechanics are used, what do you want to do with the scum. ”

"23333, just pretend to be forced, just be happy. ”

"This one forces me to give full marks. ”

"In the world of scholars, are they so fresh and refined? Eat the dirt and eat the soil. ”

"Hahaha, don't be too high-profile, the grave grass is already a foot high!"

Chen Ergou smiled and explained: "What's so good about pretending, I just know the content of this principle, and it is not okay for me to study it in depth." Bernoulli's principle is simply explained, that is, you fold a small paper bridge with paper, blow air into the bridge hole, and the bridge deck bends down, instead of drumming. In this way, the side with a small gas velocity creates a lateral pressure on the side with a large velocity, and this force is called static pressure. That is, the second form. ”

And when the sailboat sails against the wind, it is under this static pressure that it moves forward. According to Bernoulli's principle, theoretically, when I keep the bow at an angle of 30~40 degrees to the direction of the sea breeze, the pushing efficiency is the highest. ”

"As far as I know, in August 2000, the French-designed sailing yacht Hydroptere reached a speed of 35 knots, almost 70 kilometers per hour, even when the wind speed was only 15 knots. ”

"Isn't that scary? But that's the objective fact. Compared to him, my whale can only be described as turtle speed. ”

The wind was not very fast at sea now, but he felt that the Whale was sailing far faster than it had been last night.

It's just the vast sea, as far as the eye can see, the sea and the sky are connected in a line, except for the water is still water. Not to mention the islands, you can't even see a single seabird.

His food and water were running out quickly, and the Whale continued its seemingly never-ending journey. If he hadn't been sure that he was on the right track, it would have been terrible to lose his way on the sea.

And just like that, more than an hour passed.

Suddenly, Chen Ergou felt that the sea was not calm. [Animal Taming] told him that there was an intention to move under the sea, and a very large and noisy message was transmitted. This wared him: "What happened?"

The audience didn't know why, and followed his gaze to look at the sea where there was nothing.

"Nothing?"

"No...... Wrong. ”

Suddenly, several large fish jumped up on the sea level, jumped out of the water and fell high into the water, splashing a large wave.

The whole sea was churned and churned, and the speed was extremely fast, and in the blink of an eye, it was in front of you.

"Dolphins!"

"Oh my God!"

"Lots of dolphins!"

Chen Ergou's eyes were sharp, and he instantly discovered the true face of these big fish.

The live broadcast room was boiling, and everyone who saw it was dumbfounded-

"A big wave of seafood is coming. ”

"it, dolphins migrate. ”

"Dolphin sound, I heard it, it's a real dolphin sound, haha. ”

"it, it's a spectacular picture, it's worth watching it once in my life. ”

Dolphins, usually people can only see them in the aquarium. That figure, that body shape, that charming smile, are all well-deserved darlings of nature! Usually people can see one or two, and that is very strange. However, thousands of dolphins migrate in the vast ocean below the surface of the sea, and from time to time they leap out of the water and compete with each other, like thousands of arrows in unison.

Such a large-scale dolphin migration is truly spectacular.

That scene is simply amazing, there are thousands of them, rare in a hundred years, magnificent!

Chen Ergou controls the dog egg on the water surface to aerial photograph this dolphin migration, with silver-gray dorsal fins, a white belly, and a smooth and curved nose. Swam quickly from afar, and in the blink of an eye, you came around the ship.

There are also a few cheerful chirps, the sound is crisp and pleasant, this is the real dolphin sound.

Chen Ergou was excited in his chest, but he felt that his chest was blocked, and he only felt that there was too much excitement to express. glanced at the popularity in the live broadcast room, and it has soared to more than 16 million.

In such a scene, it is very necessary to sing a song.

spent 1 million popularity to buy a song, and a fast-paced and cheerful piano prelude suddenly began to sound in the live broadcast room.

Chen Ergou grabbed a large conch shell and stood at the bow of the boat to blow it, struck the bamboo tube with bamboo chopsticks with one hand, making a rhythmic sound of empty sound, and shouted loudly: "Friends, blow the horn, beat the war drums, let's start the performance, prepare to open your eyes." ”

"A new song is here, please enjoy and advise. ”

He flaunted like a circus clown, declaring awkward presiding lines.

The exaggerated movements, even I was amused, and a hoarse laugh came out of my slightly hoarse throat. Suddenly, he shouted at the top of his throat and shouted wildly, in response to the chirping of dolphins. The howl gradually rose and fell, and the long howl turned into a rhythmic chant, and some hoarse voices echoed between the sea and the pods of dolphins.

Yeah， you could be the greatest， you can be the best

You can be the greatest, and you can be the best

You can beat yourself in the chest like King Kong

You can conquer the whole world, you can win wars

You can talk to God and knock on His door

You can put your hands up, you can fight against time

……

At first, the audience was a little stunned because the song was in English. But then the beautiful tune, like a rousing movement, makes people addicted to it.

And so it is.

The singing is passionate and enterprising, and it is inspiring. The theme of the song is to follow your dreams, the world changes because of you, and the inspirational notes and touching rhythms hit it off.

In this vast and passionate sea, even greater decibels were released, and as the scattered wind swept through the waves and boats, he did not notice that the loud chirping of the dolphins around him seemed to be more loud.

In his consciousness, he seemed to perceive that the wind and the sea resonated in his song, and the scorching sun above his head suddenly became less dazzling, and a dark cloud shrouded his head, blocking the direct rays of the scorching sun, but the sea became more and more brilliant and bright.

You could go the distance， you can run the mile

You can stay the course, you can travel thousands of miles in a day

You can go straight through hell with a smile on your face

You can be a hero, you can get gold medals

Break records that others thought were impossible

There will be a day

The whole world will know your name

Because you are the brightest flame of all

Be a champion！
