When diving, there is a different probability of encountering the Shanghai stream depending on the dive site.

The downward flow the name speaks for itself is the downward current. This can be seen from the bubbles exhaled from the mouth of the three people. The originally rising bubbles suddenly circled around the body and then began to float downwards. The two turtles who went away, but not far away saw that the situation was far from good and retracted into the rock crack, and at the same time the vision of the three people began to become muddy.

Fortunately, except for Zhang Heng, the other two are not newbies. This is not the first time that Han Lu has encountered an ocean current. Therefore, he will not be as flustered as a beginner. Han Lu is next to the stone wall. Put your body on the stone wall and grab the stone wall like a gecko.

Nelly turned on her flashlight and took a picture of a big rock nearest to Zhang Heng, signaling Zhang Heng to go over, and she also went there herself. The two people were not falling fast, which means they encountered The current is not strong, which makes Nelly relaxed, and Han Lu and Zhang Heng are also very calm.

The most dangerous thing under water is to fall into a panic. Not only can you not solve any problems, but the random struggle will accelerate the consumption of oxygen, and the wrong operation is likely to cause more trouble. Han Lu has enough diving Experience Nellie is not too worried, she is really worried about Zhang Heng on the other side, especially the latter just asked to ascend, but in the blink of an eye, he encountered a current.

Fortunately, as of now, Zhang Heng not at all was in a panic, swimming with Nelly to the rock.

About a minute and a half or so, Nelly felt that the current was getting smaller, so she gestured and asked Zhang Heng how much gas he still had.

Zhang Heng looked at the residual pressure gauge, which showed that he still had about 120 bar of gas. The three people stayed underwater for a short time, and they basically moved at a depth of about 3 meters, not at all. The dive was too deep. , So the gas in the gas cylinder does not consume much, and it is still far from the warning line.

But since Zhang Heng has decided to ascend, Nelly, as a dive guide, certainly has no reason to continue to dive, but before ascending, the two still need to join Han Lu at the stone wall.

Unlike the relatively clear seawater before, because of the influence of the current, it brought a lot of sand and impurities, and the visibility in the water became very low. Nelly turned on her flashlight again, but I don’t know if it was due to lack of power. The flashlight in her hand flashed several times this time before it gradually stabilized.

However, when Nellie moved her flashlight to the rock wall where Han Lu was, she suddenly found that there was no shadow of the latter.

Nelly blinked, she seemed a little unable to believe what she saw in front of her, because when Lu came down, Han Lu was the first person to find a place where she could fix her body, and apparently she was out of sight at the time. Dangerous, after that, the three people were separated by less than two minutes. Han Lu justified leaving this position in such a short time.

Nelly turned the flashlight to other directions nearby, and the silhouette of the searcher Han Lu, but there was no receipt, and at this time, Nelly saw Zhang Heng gesturing to her and pointed to the top of her head.

Nellie thought it was Zhang Heng who found Han Lu, but when she looked up, she saw the strange scene she had never seen in so many years of diving experience, only to see that the sea of ​​water above them was visible with naked eye The speed keeps turning red.

Is this a red tide?

Nellie lives by the sea. Although she has not seen the red tide in person, she is not unfamiliar with this natural phenomenon. Red tide is generally caused by some phytoplankton, bacteria or protozoa in the seawater that explode or reproduce Caused by high concentration, it will discolor the seawater and cause great harm to the environment.

However, this Sea Territory is a famous diving spot on Yonaguni Island. The residents of the island have always attached great importance to the ecological environment. For many years, the nearby Sea Territory has never experienced a red tide, and the red tide generally affects the upper sea water, Nelly. But found that the red piece above his head was approaching them quickly.

Soon the 2 people are also filled with red seawater, the color of these seawater is actually very close to human blood, surrounded by this is very infiltrating people, and the most important thing is that they will further reduce the visibility, now Ni Li can only see a distance of less than 2 meters in front of her, and even the silhouette of Zhang Heng has become indistinct.

Even with Nelly ’s rich diving experience, I ca n’t help but feel anxious now, mainly because this strange “red tide” appeared sooner or later, by chance at their point of looking for Han Lu, let the next The search job suddenly became difficult.

Nelly wanted to take Zhang Heng up first and then come back to find Han Lu herself, because Zhang Heng had already asked her to ascend before the descending stream appeared, but the divers needed time to ascend because the pressure at different depths was different. At deeper depths, nitrogen will dissolve into the blood.

At this time is mainly the danger of drunk nitrogen mentioned earlier. At this time, nitrogen is dissolved in the blood, and if the pressure is reduced rapidly, the nitrogen dissolved in the blood will precipitate out and cause thrombosis. Divers suffer from diving sickness, but they can directly explode their lungs.

Therefore, when ascending from the water, it is necessary to have a safe stop time. It will take 70% of the fastest time when Nelly sends Zhang Heng to the ship and comes back. Let me say whether she can get her wish in the blood-red water. Going back to where she is now, Han Lu was not in the vicinity at the time, so it’s hard to say, and the gas remaining in her cylinder may not be enough to support her to conduct a search for too long.

If at ordinary times, Nelly can choose to take Zhang Heng together to find Han Lu, but due to the effect of this strange red tide, as long as the two people are slightly separated, they may not see each other. In this kind of bad Under the circumstances, Nellie is not confident that she can still take care of Zhang Heng when looking for Han Lu.

Han Lu has disappeared. Don’t lose Zhang Heng again.

After a short period of thought, Nelly decided to take Zhang Heng up first, because she also had a luck in her heart, maybe Han Lu had already stepped back to the ship first, and they could see each other when they floated to the surface. And speak frankly, even if she now takes Zhang Heng to venture to Han Lu, it is actually just try one’s luck.

But as Nelly was about to ascend with Zhang Heng, she seemed to catch a glimpse of black shadows passing by her in the afterglow of her left eye.

Will that be Han Lu? There was a hint of hope in Nelly’s heart. Although the shadow just passed quickly, she still saw a rough outline. It was indeed like a person wearing a diving suit.
