"Humpback whales swim slowly, about 8 to 15 kilometers per hour."

"When their mouths are opened, their special elastic ligaments can temporarily cause the lower palate to fall off temporarily, forming an angle of more than 90 degrees, and the transverse diameter of the mouth can reach 4.5 meters, which can swallow a large amount of krill or smaller fish in one bite."

"But the diameter of their esophagus seems too small, and it is very vivid to imagine the horns we have seen in our lives;"

"Humpback whales cannot swallow larger foods, so scaled shrimp, scaled fish, capelin fish, and stubble fish... are their main foods."

Unfortunately, Li Ming's passionate commentary did not turn the audience's attention to him, even if he asked the system to open a small screen in the lower right corner.

These happy family composed of these three humpback whales is now the protagonist of the live broadcast room.

But soon, Li Ming gained something, and the sonar showed that there was something under the seabed!

The water depth here is only 20-30 meters, and some of them are even only a few meters to more than ten meters;

As the humpback whale family gradually moved away, when the drone returned to the yacht, Li Ming, who was holding an underwater metal detector, had already put on his whole body of equipment and was about to be launched;

When the water friends saw this outfit, they asked him if he had made new discoveries.

While detecting what he carried with him, Li Ming explained with a smile: "Just just now, I found something under the water. I plan to go down and take a look!"

"If you watch my live broadcast, brothers who are interested in diving must pay attention. I have always forgotten to tell you."

"When diving, you should pay special attention to the weather conditions. Cloudy, rainy or windy weather is not suitable for diving, because the waves mainly come from wind. Usually, cloudy and rainy days will have stronger winds and lower temperatures.

"When the wind is strong and the waves are strong, not only will you feel very uncomfortable when diving, but you will also consume your physical energy excessively. In addition, the low temperature will also cause physical discomfort and may also cause accidents..."

After saying that, he dived underwater with his back, and the footage of the live broadcast room also switched from the drone to the camera on his diving helmet.

From the blue sky to the azure seabed, the refraction of the sunlight through the sea water has been much more eased. The sea surface above him is getting farther and farther away from him, and the seabed is still quiet and peaceful.

A Kempli turtle quietly swam past Li Ming's right hand, which surprised him particularly.

He pointed to the gray-green Kemp's turtle in the distance and said

"Brothers, this is a guy, but it is quite precious. It belongs to the "IUCN Red List of Endangered Species" and only a few thousand of them are in the world."

"This is the smallest species in the turtle population. It has no teeth, but has a wide beak like a bird's beak, and mainly eats some seaweed, jellyfish and sea urchins...."

[If you don’t say it, I thought you had a Codonopsis and Turtle Soup for dinner today!]

[We will call the police after eating!]

【Tell yourself that it is a protective animal...】

Seeing that the barrage in the live broadcast room became more and more obedient, Li Ming quickly changed the subject.

"When we dive, we should always look up and pay attention to the surrounding conditions, including the distance from the shore, weather conditions, whether there are ships nearby, and vehicles on the water..."

When he dived to 5-10 meters, the sea water was still very clear.

But when she reached the bottom of the sea 15 meters deep, something happened.

The place where he dived was close to Dry Turtle Island, which was affected by ocean currents such as the Gulf of Mexico warm current and Peruvian cold current. What's more, the underwater undercurrents are everywhere, and the water flow stirs up waste everywhere in the sea sand, causing the seabed to have turbid vision.

Li Ming took a look at the depth meter. He was only 19 meters away from the water surface;

In fact, the surroundings were not dark, and there was no problem that the sunlight penetrated this depth of water, but he could not see clearly the surrounding situation at all, and could only see the white sand and stone seabed under his feet.

Even he turned on the high-power searchlight he carried with him, but he couldn't see clearly the place around him 3 meters away. His eyes were filled with sand and dust after being stirred up by the water flow.

Now let alone treasure hunting, it is even more difficult for Li Ming to identify the direction under the water like this, even if it is even more difficult for him to distinguish the direction under the water.

The audience sitting on the computer screen was even more confused. They only heard the sound of Li Ming's ventilation, and the sound of bubbles forming "gurgling" on the seabed when the oxygen box vents carbon dioxide from the oxygen box behind him was removed.

[Barrel protection, nothing can be seen]

[High-energy warning prompt, you can easily lose your direction now]

[Brother Ming probably doesn't even know where he is now, and the surroundings are turbid]

The audience began to worry about Li Ming's physical safety, fearing an accident.

When Li Ming saw the situation in front of him, he knew that it was almost impossible to find that thing under such circumstances, but he could freely solve it for the lost side.

He said with a confident smile:

"For an old sailor like me, there are many solutions to lose direction on the seabed. Next, I will demonstrate it to you."

"We can think about the reference objects and find a way out when we get lost on land, but there are few reference objects in the ocean, unlike on land where we have high visibility and many reference objects. If you don't bring a compass and depth chart, please refer to my approach."

Li Ming pressed the exhaust port of the oxygen box behind him, took a deep breath of oxygen before vomiting it out, and then let go, and then saw a huge bubble forming on the seabed.

The huge bubble quickly escaped from everyone's sight, and the king flew over his head.

At this time his magnetic voice rang again;

"Because the air is insoluble in water and has a lot of density than water, the bubbles that I exhale will now rise vertically."

"When we lose our sense of direction at the bottom of the water, we just need to swim in the direction of the bubble rising. If you can't figure out whether it's tilting or what, pay attention to the upward direction of the bubble and judge your posture."

"If you float halfway, you don't know whether you are rising or diving, pay attention to the speed of your exhalation bubbles rising."

"If the minimum bubble in the spit bubble rises faster than yourself, then you prove that you are in a stay or in a down state, and if you are rising faster than the bubble, you are in an up state."

Suddenly, this wave of professional operation demonstrations was recognized by the audience, and various gift special effects began to seize the position of the comment area.

[The old driver is indeed excellent. This wave of operations is OK. You can apply for a card!]

【Learn, it is impossible for me to dive in a landslide】

.....

After explaining here, Li Ming swam quickly towards the sea in the direction of the bubble;

Soon, he returned to the clear and clean water area again, where the water flow was much smoother and the surrounding vision became wider.

For this difficult situation where the visible range of the seabed is extremely low, Li Ming had already arranged a response when he set out in advance.

But just returned to the yacht, he hadn't waited for him to take out his secret weapon;
Chapter completed!
