On the sandbank, the Xiangrui troops fought again, and in the water, Ji An turned his head down, gently swinging his flippers.

Putting on a wetsuit is equivalent to an extra layer of skin, which can largely isolate the external water temperature, which is something he can't do even if he wears a locust crown.

Slowly crossed the dividing line four meters underwater, and under the effect of the wetsuit, it was a little chilly, but it didn't feel that cold. Maca suspended and stopped and asked Ji An about the situation with gestures, Ji An nodded, and the two continued to dive.

Descending from the sandbar, there is a vertical cliff, and at a depth of 6 meters, there is a "platform" protruding from the cliff wall, where the two of them stay.

In fact, 6 meters of water depth is not a matter for most young guys, a fierce thing, but Maca is a practice instead of teaching, and Ji An is the first time for the first brother, if the chief is played bad by her, the fun will be great, so Maca still slows down the pace, nine shallow and one ...... No, from shallow to deep.

This has to be replaced by the female bandit Anji, knowing that Ji An is really durable, and the diving speed may be slow, but until Ji An can't stand the water pressure and stops by himself, Anji will not follow him step by step, and a wave will directly make him ****.

The two stopped on the "platform" at 6 meters, and Maca asked Ki'an to try adjusting the buoyancy balancer.

There is a hallmark distinction between novice divers and veteran drivers, depending on whether the diver can "hover in place" underwater and "volley" in motion. The oxygen tank itself has a lot of weight, just like a person carrying a stone into the water and sinking straight down, at this time a buoyancy balancer is needed to adjust the balance between buoyancy and gravity.

In addition, Maca also demonstrated various underwater marching movements to Ji An, such as when there are many obstacles, when the hands and feet cannot be stretched, they can provide forward momentum by holding water on their chests with their hands.

And this action is also useful when parachuting, or in other words, diving and skydiving are similar in many places, after all, they are both called diving in English.

The biggest common denominator is that safety comes first, and in the final analysis, it's all about playing with life. Whether it's worth it or not has to vary from person to person, some people feel that it is purely painful, impatient to find excitement, and some people think that this is the wonderful thing about life, people live a lifetime, and they always have to experience something different.

Ji An played by himself for more than ten minutes, and his physical strength didn't need to worry about Maca at all, seeing that it was almost over, Maca signaled to continue diving.

The two stepped out of the platform together.

Soon after, Ji An touched the bottom of the waterhole at a depth of 12 meters, as long as he slowly adapted, always pay attention to keep breathing, this pressure is nothing, many instructors take newcomers to experience diving for the first time can go down to 40 meters. As for the newcomer's discomfort the next day, endure it and pass~

"Hiss" "Gurgling...... The quiet underwater world unfolded in front of Ki'an's eyes, and he could only hear the sound of water and his own breathing through the respirator.

The waterhole was clear, and Ji An looked up, and under the direct sunlight of the Serengeti, it seemed that pillars of light were thrown into the water, and they appeared shadowy with the water waves.

The visibility under the water is still very high, and the green aquatic plants around them float in the water, gently swaying with the movements of Ji An and Maca, and groups of small fish swim and wander among the aquatic plants, curiously looking at the two-legged beast that they saw for the first time.

Claustrophobia can go berserk here, but divers enjoy a different kind of tranquility and the laws of physics that are very different from those on land.

Observe the surrounding environment, judging from the experience of the anchor Fat Tiger and the first brother in the live broadcast circle, the underwater live broadcast will definitely be welcomed by his audience, and among the more than 20 million viewers who are tired of the noise of the city, there may be many people who will be deceived by him.

The live broadcast can't be opened today, and Ji An, a beginner, doesn't know what situation he will encounter, in case he has to open the door and escape, it will be embarrassing.

There is also the fact that the auspicious troops on the water cannot be exposed, and the dragon descending Arhat that you may encounter later, and you don't know what it looks like.

However, Ji An does not have much hope for this, people do not want to meet, and it is an underwater creature, even if Ji An has a tail fin, he can't catch up, and today he is still mainly learning to dive.

Maca patted Ji An on the shoulder, pointed ahead, Ji An nodded, adjusted the balancer, kicked the flippers, and swam forward against the aquatic grass layer and Maca.

The bottom of the pond is shallow at the edge and deep in the middle, showing a slope of slope downward.

There were some trees that had fallen from the shore around, and Ji An was still wondering if it was a gloomy wood, so he touched it with his hand, and it immediately became rotten and dented.

After tens of millions of years of oxygen-free carbonization, these fallen trees will only be eroded and decayed by microorganisms in the water.

There is no one here all year round, to be more precise, no one has ever come, there are many big fish under the water, and Ji An saw many tilapia weighing more than ten catties hiding in the grass and secretly looking at the two-legged beast.

As for some 2-meter-long African giant catfish swimming by, Ji An's rhinoceros skin and eight suits are not vegetarian, but Zhan Lu does not dare to use them, and the sharp runes will scatter as soon as they see blood.

Sticking to the bottom of the pond diagonally downward, Ji An followed Maca for a while, and unconsciously the water depth showed that it was already 21 meters, Maca stopped, pointing to the edge of the east side of the cliff, where there is a "stone cave" with a diameter of less than 1 meter, and you can see the faint water lines.

If nothing else, this should be the entrance to the underground dark river that connects the outer tributaries, that is, the place where the dragon descending Arhat enters and exits the waterhole.

It's a pity that it's too small, Maca tried it, and she barely passed, but it was too risky, and she might not be able to get out if she squeezed in. Moreover, the oxygen tank will certainly not be able to hold them up for a distance of more than 20 kilometers.

Ji An didn't expect to find the Dragon Descending Arhat, but he had nothing to do anyway, so he just played.

The most important thing underwater is to avoid panic.

When man enters the water from the land, he is in a world that is completely unfamiliar and even the laws of physics have changed, which is equivalent to entering one realm from one realm to another, in the metaphorical parlance. There are rules in the water world, people come across the boundary, whether they are swimming or diving, they must abide by the rules here, as long as they master and use them properly, people can have fun here, and even some people who deeply understand the rules, two people can share a breathing apparatus to escape.

And any door in Ji An's hand is equivalent to a magic weapon that can break the boundary, so the rules of the water world can be said to be invalid for him, and if he can't do it, he will slip away, which is very convenient.

With confidence in his heart, Ji An, who dived to the bottom of the pool more than 20 meters deep for the first time, began to wave.

After adjusting the balancer and slightly reducing the buoyancy, Ji An walked into space, that is, compared to the moon, the water resistance is a bit large, he continued to reduce the buoyancy, and walked the underwater world with the oxygen tube on his back, a new world that covers more than 85% of the earth's area, most of which has not been explored and unknown.
