Looking at the anxious fishermen, a group of tourists are confused.

They calmly looked at the sea, the water was surging slowly, and the white waves were rushing to the shore one after another, looking like an ordinary high tide.

And the beach that the villagers stretched out their hands to point to was even quieter, and there were waves beating around, and the sea water that came over here was relatively calm, and there were no waves, so it slowly surged up.

The layman looks at the bustle, and the insider looks at the doorway.

Compared with the old sea ghosts in the village, Ao Muyang can only be regarded as half an expert, he didn't see anything wrong with this wave, but he understood the word shouted by the villagers: offshore current!

Offshore currents are also called fault tides, and foreign currents are also called rift currents.

This is mainly due to the fact that when the waves hit the shore and are hindered by the land, they break up, and a large amount of sea water rushes up to the land and has to find a way back to the sea, but because of the push of the subsequent waves, the sea water will initially move in a direction parallel to the beach, and finally converge into one or more strong currents to return to the sea, and this process is constantly repeated.

During its circulation, there is no problem with the first half, as is the case at high tide, when the sea rushes to the land.

The problem arises in the second half of the cycle, when a large amount of sea water flows parallel to the beach, followed by a tidal wave that collides and creates a whirling force, like a whirlpool.

In this case, if someone stays within the influence of the current, it is easy to be swept into the sea.

Ao Muyang remembers reading a document that was the result of a long-term study by maritime emergency agencies in Brazil and Australia, which showed that about 90 percent of drowning in Oceania and South America was caused by rip currents.

In the United States, about 150 people drown each year due to offshore currents, which is more than the number of people killed by storms, hurricanes and tornadoes combined!

Seeing an offshore current, he immediately ran into the sea.

Offshore currents appear silently, because they are inconspicuous on land, so it is generally believed that they appear unsuspectingly, and can occur in any weather conditions, until someone is caught in the middle of it and realizes that they are in trouble.

But then it will be more difficult to get out of trouble, and the speed of the typical offshore current is about 2 meters per second, which is faster than the average person's swimming speed.

Because of the high speed of the current, it has a suction force like a whirlpool, so once you get caught in it, not only ordinary water riders but even lifeguards are often pulled out to sea, resulting in drowning.

That is, this time there were many people on the beach, and there were many veteran fishermen staying here, who had experience, and saw that the tide was surging along both sides, and the water was darker and there were almost no waves, so they judged the identity of the offshore current: there is a local proverb about this kind of disaster, which is called 'white waves and green water, whoever wants to go down will regret it'.

Otherwise, there are so many people on the beach today, and the offshore current suddenly threatens to threaten, and many people will definitely encounter danger.

Hearing the anxious and frightened voices of the villagers, the tourists knew that something was going on and left the beach and ran to the beach.

Ao Muyang went in the opposite direction, he shouted while running towards the sea: "You must leave the sea, you can't let the waves touch, especially the child, hurry up and pull the child up!"

There are small whirlpools on the rip current, which can be dangerous even if they don't reach people's knees, and the hidden eddies below the surface of the water can overturn people, and it is dangerous if they fall to the ground and fall into the water.

Amid the shouts of him and the villagers, the people left the place where the tide was rising, but they were able to leave in time because they were already on the shore, and there were still people in the sea.

The people in the sea found the danger, and two of them stayed in the sea, and they were so frightened that they tried to raise their heads above the surface and rushed to shore with their hands and feet.

There are family members on the shore who are so anxious that they jump to their feet: "Come on, help, my husband is in the water!" "Dad, hurry up, come up, it's dangerous!"

Ao Wenchang's father, Ao Qianyao, rushed to the shore and shouted: "You two steady, steady! Don't swim any further, it's useless to fight against nature! Listen to me, you don't have to try to swim back to the shore against the current, you stay calm, will you tread water? Tread water, show your head! Can you float? You steady, let's go to the boat!"

His voice was not loud, but it was at high tide, and the sound of the tide crashing on the shore was drowned out, and the two people in the sea were already panicking, they wanted to go ashore against the current, but they swam farther away from the shore......

That's the terrible thing about the rip current, it sweeps people back into the sea, and it flows faster than people swim, and falling into the rip current is like falling into quicksand, the more you struggle, the deeper you fall.

The reason for this is that the flow of the sea water in the offshore current is inconsistent, which is a balance in itself, and the struggle of man can break this balance!

Ao Muyang was about to jump into the water, he knew that it was too late to send a boat, because the two people in the sea would be too panicked, and they would struggle more and more, and when the sea water choked into their mouths, the two would be finished!

Seeing him go into the water, Ao Qianyao hurriedly grabbed him: "Don't, don't rush into the water, village chief, let's hurry up and drive the boat to throw a lifebuoy, people have to plant a ...... one by one"

"It's okay, I can handle it!" Ao Muyang pushed him away and jumped into the water amid the nervous screams of tourists and villagers.

When you look at it from the shore, there is no difference between the offshore current and the ordinary ocean current, but after going deep into the sea, you will find that the seabed where the offshore current occurs is lower than on both sides, and there are white waves on the surface of the sea rushing to the shore, like an ordinary high tide, but the water below the sea water flows to the middle of the sea, which is like a low tide, which is exactly like this, which leads to the emergence of a seawater vortex.

He found the two people in the sea for the first time, Jin Dan reversed, and Ao Muyang accelerated closer to a man.

Rip currents are troublesome for ordinary people, and for him they were nothing at sea, but when they came back from their trip to the South China Sea a year ago, they encountered a storm at sea, and the scene was much more terrifying than it is now.

Approaching the panicked man, Ao Muyang grabbed his chest from behind, and his arms passed under his armpits, just avoiding his arms.

He surfaced to let the man breathe a sigh of relief first, and then saw the general swimming after him, so he pushed the man to the general and said, "Brother, hold this dog's belly, don't touch its limbs!"

The man was flustered, but he could see that his swimming skills were good, and his psychological quality was also good, and after finding that someone came to save him, he temporarily stabilized himself, and after hugging the general, he cooperated with the treading of water, and no longer struggled indiscriminately.

The other man was even worse, he had already sunk into the water!
