"If you want to explore the seabed, you must start with a deep dive!"
......
Deep dive.
An advanced swimming posture.
It is often regarded as one of the must-learn skills by some swimming enthusiasts.
The key lies in the depth of the dive.
Some people who have undergone professional training can even dive to a depth of four or five hundred meters to experience the limits of the human body.
However, Ren Yan never intended to teach his students in this way.
Just go down to the bottom of the sea and take a look. It's about 50 to 60 meters deep.
Of course, the most crucial thing is that, to dive four or five hundred meters, Ren Yan feels that even if he knows the technique, he probably won’t be able to do it.
This thing requires not only skills, but more importantly, talent.
A talent that allows one to compress one's lungs infinitely.
So far, as far as Ren Yan knows, the only people who can achieve this are those who make a living from it.
For ordinary people, the maximum distance seems to be only about 200 meters.
"Alright, everyone, follow me!"
Ren Yan, who had put on his diving equipment and avoided the students to a certain extent, stood in front of his students again and began to explain deep diving.
"Deep diving is actually no different from your usual treading water swimming."
"It's just that the sea surface is replaced with the sea, and the techniques used are basically the same."
"It might even be easier because this time you have tools like flippers that can give you a lot of power."
"There are only three points you need to pay attention to."
“The first point is the wearability of the equipment.”
"The exposed areas of your wrists and ankles must be as close to your skin as possible."
"The second thing is to fix the flipper. If it really falls off on the seabed and cannot be rescued, the other flipper will also have to be removed."
"Otherwise, there is a high possibility that it will cause your body to become out of balance, leading to some unnecessary accidents."
"But the above two are just trivial matters."
"The most important thing is the choice of oxygen tank and mask."
"The oxygen tanks used for deep diving are generally between 0.6 and 60 liters, and the material used is usually lighter aluminum."
"But even if they are made of aluminum, their overall weight will vary greatly, and this weight will bring different levels of difficulty to your infiltration."
"So, be sure to choose the oxygen tank that best suits your physical condition."
"Don't ever think that you can stay in the sea longer because of the large capacity. This idea is very dangerous."
"I don't want to tell you more about the principle of biting off more than you can chew."
"As for the best place for the oxygen tank, just put it on your back, like I did."
"Use the breathing tube on the mask and connect it to the oxygen tank to achieve the purpose of spontaneous breathing. Similarly, breathe in through the mouth and out through the nose."
"If the breathing tube breaks during the journey, you must ascend as soon as possible and replace it with a new one."
After saying that, Ren Yan demonstrated the real thing in front of everyone in Class Nine.
The drone also synchronized this scene faithfully to the live broadcast.
For a moment, netizens even felt a little nostalgic.
They have all forgotten how long it has been since Teacher Ren taught like this.
“The second point is to dive down.”
"There are two main ways. The first is to raise your hands and use your own weight to naturally dive to the bottom of the water."
"This method is safer, but less efficient."
"As for the second method, it is to dive into the sea headfirst and work in reverse by treading water, sending yourself completely to the bottom of the sea."
"This kind of technique is fast, but requires relatively high skills."
"If you are skilled at treading water, you can give it a try."
“The final difficulty is also the most important difficulty.”
“Overcome your fear of the deep sea.”
"In the deep sea, you will experience a sense of claustrophobia. This claustrophobic feeling will make you feel uncomfortable and even stiff."
"These are normal physiological responses of organisms to danger, just like animals playing dead."
"But if this really happens at the bottom of the sea, then you will face true death."
"So what you need to do is to adapt, adapt from diving to deep, step by step, to overcome your psychological fear of the ocean."
After saying this, Ren Yan pointed to the boat:
"I have said all that needs to be said. Now go to the ship's warehouse and find your deep-diving equipment and follow me in a practical exercise."
After these words were spoken, everyone in Class 9 was stunned for a moment, then they rushed up like the wind and found the deep-diving equipment that their teacher had hidden deep in the warehouse.
Although they didn't know how likely their unlucky teacher would buy these things.
But they do know where the teachers usually spend the class funds.
It’s no wonder that the other side’s team fee always starts at tens of thousands. Just looking at the quality of the deep-diving equipment, you can tell that it’s not cheap.
Unlike other students who happily chose equipment that suited their body shapes and ran back to this strange island.
Ah Wei looked at the equipment in his hand, with only one thought left in his mind.
"Should I have a good talk with my teacher?"
He doesn't mind buying things, but should I have a good talk with him about the types of things to buy and the amount to be spent?
Otherwise, how will I keep accounts in the future? !
......
Ignoring the confusion in Wei's heart.
After confirming that there was no major problem on the island, the teacher prepared to take the students diving again.
