Chapter 905 Underwater Ruins

It is June now, and the sun is still relatively abundant. Therefore, when the three of them were on the boat, they all felt a little stuffy in their wetsuits. However, this stuffiness disappeared after entering the water, especially as the depth continued to increase, the temperature also began to increase. Gradually decreases.

Because the thermal conductivity of water is much higher than that of air, people lose more heat in the water than on land. Fortunately, there are diving suits to keep out the cold, and recreational diving like this generally does not dive too deep. , because of the pressure, every 10 meters of diving in the water will increase the pressure by one atmosphere, and there will be a danger of nitrogen intoxication after more than 30 meters (ordinary recreational diving cylinders are mainly filled with compressed air, which is 21% Oxygen and 79% nitrogen. High pressure will cause nitrogen to integrate into the body. Similarly, breathing oxygen under high pressure for too long can also cause oxygen poisoning).

The underwater ruins that Zhang Heng and the others went to this time were probably at a depth of about 25 meters. There was basically no danger at this depth. With Zhang Heng's water skills developed in the Black Sail copy, even without any equipment , he can dive to this depth with just one breath. Of course, in that case, he won't be able to stay down there for long. Basically, he will have to go back for air when he sees the ruins.

Strictly speaking, this visit to Okinawa is not Zhang Heng’s first time diving.

When he was a child, he went to see corals in Sanya with his parents, but it was a purely family-oriented leisure activity. The depth of the dive was less than eight meters, and the time he spent underwater was also very short, only twenty minutes, and there were many people in the whole process. Accompanied by coach.

To put it into perspective, when Zhang Heng wore equipment and stayed underwater for a long time, it was still in the Apollo training camp. NASA used the underwater environment to simulate weightlessness. Zhang Heng not only had to stay underwater, but also had to receive signals from there. The console instructions complete a series of operations.

Therefore, Zhang Heng didn't feel unfamiliar when he returned to the water.

Whether it's the feeling of weightlessness or the quietness underwater, the seawater isolates almost all sounds. Every diver can basically only hear his own inhalation and exhalation when diving, especially his exhalation. When you are inflated, the bubbles pass through the sea water and float upwards, making a very reassuring sound.

Nelly was indeed as competent as she said. She always stayed no more than two meters away from the two of them, closely watching their physical and mental conditions and confirming that they did not encounter any trouble when diving. Then she made a gesture and pointed to the ruins not far away, asking the two of them to follow her.

In fact, she didn't need to specifically signal, as long as she dived into the water, it was difficult to ignore the scene in front of her. This is a huge underwater palace or pyramid-shaped building. It looks very dilapidated from the outside. It is said that it can be traced back to about 10,000 BC.

If this submarine site was built by the people who lived here at that time, then their production technology level may have reached the level of the Egyptians when they built the pyramids, and you must know that the latter occurred around 3,000 BC.

This is why many experts firmly believe that the building made of stones in front of them is just a coincidence of nature. However, after seeing the neat stone steps and the smooth and square right-angled rock walls with her own eyes, Han Lu is still more willing to believe it. It’s really the relics left by some mysterious lost civilization.

She even saw traces of what appeared to be gates and roads.

Nili gestured for Zhang Heng and Han Lu to get closer, and she picked up the underwater camera, took a photo of the two of them with the underwater ruins in front of them, and then swam towards the gate.

Han Lu followed closely with a video recorder, while Zhang Heng glanced at the time and direction on the diving computer, and then followed.

The three of them passed through the stone gate one after another. It was said to be a city gate, but in fact it was just three pieces of stone put together. During this period, leisurely tropical fish swam past Zhang Heng's eyes from time to time. In addition, Zhang Heng Heng also saw a small sea hare.

This kind of sea creature lives up to its name. It looks as cute as a little rabbit with long ears (but it is not ruled out that there are ugly sea rabbits. There are many kinds of these things). Even a strong woman like Han Lu , even a little girl like Nelly couldn't bear the cuteness of this kind of thing, and took pictures around it, just like a photographer on the Victoria's Secret stage.

It took about a minute to move forward. After that, the three of them swam through a somewhat narrow place. At the narrowest point, only two people could be side by side. Then the field of view suddenly became wider, as if they had arrived here. In the hall of an underwater palace.

Looking around, there are walls made of rocks, and above our heads is the sparkling water.

Nili, who was leading the way at the front, stopped, folded her left and right hands together, and swung her thumbs up and down quickly. This was telling them that there were turtles to see ahead. Han Lu swam over when she saw this, and sure enough, they were there. She saw two turtles between the rocks, so she waved to Zhang Heng behind her, signaling him to follow them quickly.

But Zhang Heng seemed to have not seen her waving, and remained where he was, seemingly in a trance.

I don’t know why, when he first saw this underwater ruins, Zhang Heng had a feeling of déjà vu in his heart. However, at first, this feeling of déjà vu was not too strong, but when he came to this open-air ruins " "Lobby", this feeling appeared again, and this time, Zhang Heng knew where his sense of déjà vu came from.

He had a strange dream before in the alien copy. In the dream, he came to a seaside town with a gloomy atmosphere. After collecting the shadow set, he returned to the seaside town again. At that time, he was This feeling, and now, this feeling appears again.

Considering what happened in that small town later, this was not a good sign.

Although this diving spot is quite famous and receives a lot of tourists every year, and no one has had any accidents here so far, Zhang Heng does not want to doubt his instinctive perception.

Afterwards, he decisively gave Han Lu and Nili a thumbs up, asking for a promotion.

Nili felt a little strange. She didn't know why Zhang Heng suddenly stopped the dive. She also wanted to ask Zhang Heng what difficulties he encountered. On the contrary, Han Lu was more experienced. She and Zhang Heng had experienced the death dream incident together. Finally, he had unconditional trust in the latter, and he also knew that there was another, crazier and darker world hidden under the ordinary world.

Therefore, upon seeing this, he did not question why Zhang Heng made such a decision. Instead, he immediately made a firm upward gesture.

But then, Nelly's expression suddenly changed, and she anxiously made obscene gestures.

Please save the poor child and vote for two monthly votes... I have been looking for information on diving and Yonaguni Island recently.
