Chapter 777: First Acquaintance with Scuba Diving
Due to cultivating immortals at night, Dayu, who was called by Ji An, had not woken up yet, and was in a state of confusion, looking around curiously.
Then seeing the old elephant, the big bear greeted its chicken-eating teammates: "Oh~"
The old elephant's trunk poked out, stroked the panda's head, and the elephant emperor's version of the head touching and killing was launched.
Waiting for Ji An to pick up Aman, close the door, and tell Giselle, who was already eager to try, that they could turn around, Dayu was overwhelmed by four black girls who flew over in a blink of an eye.
The four black girls are all eye-catching swimsuits, and their figures are outstanding, even the female bandit Anji is not exempt from vulgarity, she takes the lead in occupying the favorable terrain, pounces on her chest and hugs the bear's head, and buries her face in it.
Dayu, who squatted down, was still burly, four black girls in swimsuits were in his arms, the king's breath was leaking, his mouth was hung with a faint disdain, his dark eyes stared at his chest, and then turned to Ji An: "Oh~~"
Ji An asked the parrot, "What's the dead fat house?"
Parrot: "It said there were only a few? Is there any? ”
Due to the drop in the water level, the sandbar that surfaced is located on the east side of the waterhole, and because it is still morning, the cliff wall, shrubs and trees more than 10 meters high behind it cast shadows, and it is not very sunny for the time being.
Dayu was waiting for the black girls to finish sticky, the old elephant walked aside, the huge weight left huge footprints on the sandbank, found a comfortable position to lie down, took out the PAD it packed in the GC bag, looked at the parrot, the elephant's trunk blew out a low resonance, and the parrot honestly translated: "The elephant asks you to share hot spots." ”
Ji An's mobile phone hotspot was turned on, and the old elephant used his trunk to gather the still wet sand pile, put the PAD on, and pointed the tip of his nose to the screen.
Later, when the black girls had rubbed enough of the pandas, they let go, and sent penguins to ask Ji An for the pick-up fee. Why can pandas rub in vain?
Ji An gave it a jar of fat house happy water.
Dayu crawled to the old elephant's side, sat down, held the Sprite jar in the bear's paws, stared at the screen of the old elephant while snorting the straw and dark circles under his eyes, stretched out his paws from time to time, pointed and pointed, and suggested which card the old elephant should play.
In other words, the happy landlord or Dayu introduced the old elephant to play......
The parrot grunted and Aman didn't know what they were talking about, Aman nodded stupidly, and Ji An walked up to the old elephant and asked if he could go into the water.
"Whew~" The two huge ears like sheets opened, and after listening for a moment, the old elephant looked east, and the elephant's trunk typed directly into the game dialog box.
The other two players of the game: "What dialect is this?"
"What does the landlord say?
Ji An: "I know that one, leave it alone for the time being, and talk about it when it wants to meet."
Are there crocodiles under the surface of the water? Can they go into the water?"
The old elephant listened carefully for a while, and said yes, seeing that Shizuka and Fugui were also curled up together to sleep lazy, Ji An took out a bunch of diving equipment that had just been taken out of the arsenal and put it on the beach.
In fact, he has wanted to do underwater live broadcast for a long time, but he has never had the opportunity before, and he will not use the diving equipment. However, the fangs who can go to the sky and enter the sea will, which is a compulsory subject in "boarding schools".
Taking advantage of the presence of the teacher, Ji An decided to suspend the live broadcast for a day and ask the teachers for advice on how to dive.
Mina, the black cow, is wearing a red and white floral swimsuit, the little bird is holding the arm of the black and white Dayu in the form of a person, kneeling on the beach with his side legs, watching the old elephant play cards together, Anji and Sister Hei lie back on the deck chair, one drinks beer, one snorts, wears sunglasses, and basks in the warm sunshine that has just been cast on the sandbank.
"Always remember not to hold your breath after entering the water, and always pay attention to using a respirator to keep breathing. Maca first introduced the use of the respirator, followed by the buoyancy balancer, how to reconcile the specific gravity of its counterweight and buoyancy, and some simple gestures.
Theoretical knowledge is redundant for a scumbag like Ji An, listening to it is equivalent to listening in vain, and practice is his best teacher. It just so happened that Maca thought so.
After the introduction of the two pieces of equipment necessary for scuba diving, the breathing apparatus and the buoyancy balancer, without much nonsense, go directly into the water.
Because of the crucial safety of scuba diving, it is not a matter for Ji An, it is really not good, opening a door underwater, sneaking back to Sifang Mountain, at most wasting a little water in the pool.
Maca has already worn a 5mm thick diving suit, the temperature is as high as 30 degrees today, and a rhinoceros leather that is enough to prevent rock bumps, Ji An said that there is no need to wear it, just a pair of big pants, bare-chested oxygen tubes, wearing swimming goggles respirator, stepping on the duck under the influence of flippers and walking underwater.
Maca didn't say much, since she learned from practice, she would only learn to be obedient when she tasted the hardships.
There are some tricks, if no one teaches them, and you have to take many detours on your own, such as what if you get into the water when you are underwater and your goggles get into the water?
Starting with 1 meter underwater, which is equivalent to snorkeling, Maca said on the water: "If you feel water in your goggles, lower your head, let the water gather on the lenses, and then take a breath of oxygen and blow through your nose."
With a little force, the air will squeeze the water out of the goggles. ”
Ji An did so, and the bubbles "gurgling" overflowed from the edge of the goggles, squeezing out the water in the goggles, but it was obviously underwater, but the water outside couldn't get in, which felt very magical for the scumbag.
When it reached two meters, the water pressure had already squeezed the inside of the ears, and Ji An obeyed the request to float slowly, this water pressure would not affect the body, a fierce man, Maca just wanted him to get used to it.
When Ji An surfaced and saw that he was picking his ears, Maca said: "When you go down to the water and still feel uncomfortable in your ears, pinch your nose and swallow your saliva, and the air in your lungs will balance the ear pressure." ”
It takes a process for the body to adapt to the water pressure, so that the water pressure squeezes out the air in the blood, which generally only needs to reach a certain depth and then stand still for a while.
And Ji An keeps going down and coming up, and the depth is gradually deepening, the key is that Maca wants him to develop the habit of entering and exiting slowly, entering slowly and coming out slowly, so that it will not cause strong squeezing stimulation to both sides.
Ji An was testing the limit of the water pressure in his body little by little, and the beginning went smoothly until he was 4 meters underwater.
Today, the temperature is 30 degrees Celsius, and the water in the pool is "filtered" through the underground river, which is exceptionally clear, and as the Serengeti enters the dry season and the sun is scorching, the water temperature within 4 meters is still acceptable.
But 4 meters seems to be a dividing line, once it is broken, it is like washing hands in winter below, a little unbearable, and even the color of the water is vaguely changing on this dividing line.
The speed of loss of body temperature under water is 25 times that of the ground, and the shirtless Ji An goes back and forth, up and down, and the body temperature has been taken away a lot, and after 4 meters, he shivered, slowly floated, and honestly went to wear a 5mm thick diving suit.
Ji An returned to the shore, the sun had already warmed half of the sandbar, and Anji said: "Dry your body first and then put on a wetsuit." ”
Maca seconded and said, "Then you take a break, I'll go down and play first." ”
Physical strength is not a problem for Ji An for the time being, the ginseng fruit is not needed, he drank some water, lay on the beach and basked in the sun, dried his body, and then, the three voices behind him came out at the same time
"The enemy has 30 seconds left to reach the battlefield ......"
Ji An sat up and looked back. ()
