Chapter 908

When he opened his eyes again, Zhang Heng regained his vision, which was clearer than before the red tide.

This is his first time to use [filter lens] underwater. Zhang Heng was worried about whether the red sea water belongs to the natural environment, but now it seems that [filter lens] is still effective for this red tide.

Not only did the red color disappear, but even the sea water became transparent within 300 meters.

Zhang Heng soon found the former and he separated from Nelly.

The latter is now swimming to the depth of the ruins, and in front of her, Zhang Heng's old friend, a half man half fish frog monster, is holding a flashlight, flashing a few times from time to time, luring Nelly.

Zhang Heng didn't find any other monsters nearby.

Another good news is that when Zhang Heng observed the half human, half fish frog monster for a while, he found that the Red Sea also had an impact on it, but its visibility in the red tide was still higher than that of human beings, about three to four meters in front of him.

That's why it can see Nelly, but Nelly can't see it clearly.

But Zhang Heng still failed to see Han Lu nearby.

In fact, where his eyes could reach, there was no place to hide.

However, Zhang Heng knows that Han Lu's disappearance must have something to do with this half human, half fish frog monster, so as long as he keeps up with this monster, he may be able to find Han Lu.

Zhang Heng didn't hesitate any more. After taking the mirror, he immediately swam to Nelly. At the same time, he always paid attention to the distance between himself and the monster in front of him to keep himself in the other's field of vision.

Zhang Heng sees that under the guidance of the monster, Nelly comes to the stone wall where Han Lu used to be. When Zhang Heng doubts that they have no way to go, he sees that the stone wall suddenly trembles. After that, the crack on the wall, which is about one foot wide and can only accommodate sea turtles, begins to expand, just like a giant beast opening its mouth.

The half human, half fish frog monster, who leads the way, rushes directly into the crack, then takes out a flashlight and greets Nelly behind. However, no matter how dull Nelly is, she feels a bit of danger in the face of the sudden crack.

She hesitated for a moment outside the crack, but finally found that Han Lu's desire outweighed her fear of danger, and Nelly swam into the crack with her teeth clenched.

But not long after she got into the crack, the flashlight beam in front of her disappeared.

Nelly's brain affected by the red sea water is also a little sober. She begins to feel afraid. The diving guide is not a lifesaver for divers. They do help their divers deal with some dangers, but they are only within their ability.

When the danger is beyond their scope or endangers themselves, the submarine guide also needs to know when to let go. After all, it's just a profession, and being a hero means paying for generations.

Now the situation is obviously not what Nelly can deal with, she is in a strange underwater corridor, surrounded by strange rocks, visibility is very low.

Nelly doesn't know how long the corridor is, whether there is a fork in the road, or where the corridor will take her. She has just swam a short distance forward. According to the diving computer, her depth is gradually decreasing, which is not a good sign. In addition, Nelly finally thinks of Zhang Heng who was left outside by her.

That's a big reason why she decided to turn around.

But when she came back the same way, she found another thing that made her feel extremely terrifying.

The cracks in the wall of the rock have now been closed, and they are only about a foot wide.

At this time, Nelly could not calm herself down any more. She tried to insert her palm into the crack and break off the rock walls on both sides, because since the crack can be expanded before, it means that the stone walls around it should also be movable, but reality has poured a basin of cold water on Nelly.

No matter how hard she tried, the crack was still, as if the huge opening did not exist before.

And after some intense activities, Nelly consumed a lot of compressed air and began to feel depressed. But fortunately, she has rich diving experience and has dealt with some underwater crises. Even in such a bad environment, she has not completely collapsed like those rookies.

After confirming that the crack in front of her would not open again, Nelly cleaned up her mood, checked her residual pressure gauge, confirmed her direction from the diving computer, and continued to swim along the underwater corridor.

Now, she can only hope that there is another exit ahead so that she can leave here.

Nelly turned on the flashlight, one is to illuminate the road ahead, looking for an exit, the other is to hope to get in touch with "Han Lu" again.

But then she didn't see Han Lu again, but she saw something else.

When the underwater remains of Naguo Island were first discovered, they caused a great sensation, but after that, there was no key evidence to prove that the remains were really built by a lost civilization. Even those neat looking brick walls and steps and so on may be just a coincidence of nature.In order to support the relic hypothesis, some enthusiasts even forged some coins or pottery pots with magical patterns, but these Xibei goods obviously can't stand the test of modern technology.

However, Nelly knows that what she sees now is absolutely not forged by modern people.

The wall carvings on both sides of the stone wall obviously have a very long history, but it's not hard to understand. It tells the story of some creatures that look like Mermaid hunting sea animals. In addition, there are stories of some of them falling in love with human beings, at least from the perspective of Nelly.

The mermaid gave gifts to the woman on the shore, and then they married, and the woman gave birth to children. Those children grew up for a period of time and then returned to the sea, which was quite romantic in the eyes of a girl like Nelly who had heard many Mermaid legends.

She was even fascinated by the wall carvings. Even after years of baptism and current erosion, they were still miraculously lifelike. If it wasn't for her dangerous situation, Nelly would definitely like to stop and enjoy them.

In fact, she had already taken out her underwater camera and pressed the shutter on some of the engravings.

These wall carvings are the end of the dispute with Naguo island over whether this ancient site was built by nature or by earlier human beings. Any one of these wall carvings will cause a huge sensation when it is taken to the shore.

If, of course, she can still get back to shore alive.
