Zhang Heng opened his eyes again and regained his vision, which was clearer than before the red tide appeared.
This is the first time he has used the [Filter Lens] underwater. Zhang Heng was also a little worried about whether the red sea water belongs to the natural environment, but now it seems that the [Filter Lens] is still effective for this red tide.
Not only did the crimson color disappear, but even the sea water within three hundred meters became transparent.
Zhang Heng soon found Nelly who had been separated from him before.
The latter is currently swimming into the depths of the ruins, and in front of her, Zhang Heng's old friend, a half-human, half-fish-frog monster is holding a flashlight, flashing it from time to time, luring Nelly .
Zhang Heng didn't find any other monsters nearby.
Another piece of good news is that when Zhang Heng observed the half-human, half-fish-frog monster for a while, he found that the red sea water also affected it, but its visibility in the red tide was still higher than that of humans. It looks like three to four meters in front of you.
That's why it can see Nelly, but Nelly can't see its appearance clearly.
But Zhang Heng still couldn't see Han Lu nearby.
In fact, wherever he looked, he didn't find any place to hide.
However, Zhang Heng knew that Han Lu's disappearance must be related to this half-human, half-fish-frog monster, so as long as he kept up with this monster, he might be able to find Han Lu.
Zhang Heng didn't hesitate any longer. After putting on the mask, he immediately swam towards Nelly. At the same time, he always paid attention to the distance between himself and the monster in front, so as to keep himself out of the opponent's field of vision.
Zhang Heng saw that Nelly came to the stone wall where Han Lu was before under the guidance of the monster. Just when Zhang Heng wondered that they had nowhere to go, he saw that the stone wall suddenly trembled. The upper crack, which was about a foot wide and could only accommodate sea turtles, began to expand continuously, as if a giant beast was opening its mouth.
The half-human, half-fish-frog monster who led the way took the lead and rushed directly into the crack, then took out the flashlight and greeted Nelly behind, but no matter how slow Nelly faced the sudden crack, it would be too late at this time. There was a sense of danger.
She hesitated outside the crack for a moment, but finally her desire to find Han Lu overwhelmed her fear of danger, and Nelly gritted her teeth and swam into the crack.
But it wasn't long before she entered the crack that the flashlight beam in front of her disappeared.
Nelly's brain, which was affected by the red sea water, became a little clearer. She began to feel afraid. Dive guides are not the lifelines of divers. They will indeed help the divers they lead to deal with some dangers, but that is only within their ability danger within.
And when the danger is beyond their control or endangers themselves, the dive guide also needs to know when to let go. After all, this is just a profession, and being a hero often means paying for it.
The current situation is obviously beyond what Nelly can handle. She is in a strange underwater tunnel, surrounded by strange rocks, and the visibility is very low.
Nelly didn't know how long this corridor was, whether there was a fork in the road, or where this corridor would take her. She had just swam a short distance forward, and according to the dive computer's display, the depth she was in was It is gradually declining, which is not a good sign. In addition, Nelly finally remembered Zhang Heng who was left outside by her at this time.
This is also a big reason why she decided to make a U-turn.
But when she returned the same way, she found another thing that made her feel extremely horrified.
The cracks on the rock wall before have now closed again, returning to a width of only about one foot.
At this moment, Nelly couldn't calm herself down anymore. She tried to insert her palm into the gap and split the rock walls on both sides, because since the crack could expand before, it meant that the surrounding area The stone wall should be movable, but the reality poured cold water on Nelly.
No matter how hard she tried, the crack wouldn't move at all, as if the huge opening didn't exist at all.
And after some strenuous activities, Nelly consumed a lot of compressed air, and at the same time began to feel depressed. But fortunately, she has a wealth of diving experience after all, and has also dealt with some underwater crises. Even in such a harsh environment, she did not completely collapse like those rookies.
After confirming that the crack in front of her would not open again, Nelly collected her emotions, checked her residual pressure gauge, confirmed her direction on the dive computer, and continued to swim forward along this underwater passage. .
Now, she can only hope that there are other exits ahead, allowing her to leave here.
Nelly turned on the flashlight, one is to illuminate the road ahead and find the exit, and the other is to hope to get in touch with "Han Lu" again.
But then she couldn't see Han Lu again, but saw something else.
The underwater ruins of Yonaguni Island caused a great sensation when they were first discovered, but there has never been any crucial evidence to prove that the ruins were really built by a lost civilization, even those that look very Whether it's neat brick walls and steps or something, or maybe it's just a coincidence of nature.
In order to support the relic hypothesis, some fanatics even forged some coins or clay pots carved with magical patterns, but these Xibei products obviously cannot stand the test of modern technology.
However, Nelly knew that what she saw now was absolutely not faked by modern people.
The wall carvings on both sides of the stone wall obviously have a very long history, but they are surprisingly not difficult to understand. They tell the story of some creatures that look like mermaids hunting sea beasts. In addition, there are Some of them fall in love with humans, at least from Nelly's point of view.
The mermaid gave gifts to the women on the shore, and then the two got married, and the woman gave birth to children, and those children returned to the sea after growing up for a while. This was quite romantic in the eyes of a girl like Nelly who had heard a lot of mermaid legends.
She was even a little fascinated by it. Even after years of baptism and ocean currents, those wall carvings are still miraculously lifelike. If it wasn't because she was in danger, Nelly would definitely want to stop and appreciate it.
In fact, she has already taken out her underwater camera and snapped the shutter on some of the wall carvings.
These wall carvings are equivalent to the end of this ancient site on Yonaguni Island. Whether it is a supernatural workmanship of nature or an earlier human construction dispute, any pair of them on the shore will cause a huge sensation.
Of course, the premise is that she can return to the shore alive.
