It's not the peak season for diving in Yonaguni Island.

This can also be seen from the business of the dive shop in the recent period, Zhang Heng and Han Lu are the second batch of tourists to come to dive in the past week, and as far as Nelly knows, the first batch of people will fly back at noon today.

So if nothing else, the three of them are the only divers in this sea area, and it is precisely because of this that Neli judged that the figure just now was Han Lu's, because there was no fourth person in this sea area at all.

In other words, Han Lu was probably less than two or three meters away from them, so Neli also rekindled her hope, and she even subconsciously ignored the problem that the black shadow was moving very fast.

In fact, it was not the speed that humans could move underwater, but at this moment, Nely's heart was full of joy to find Han Lu, even if she noticed the unreasonable movement speed, most of them would be explained by ocean currents or something, and because of this, Han Lu might need their help even more.

So Neli then gestured for Zhang Heng to follow her, but then she saw Zhang Heng stretch out his hand and make a stop there movement for her, and then Zhang Heng crossed his fists on his chest, and then pointed with his fists in the direction where the black shadow disappeared.

This means danger in the diving gesture.

Since Nelly has seen that black shadow, of course she will not miss it with Zhang Heng's observation, and unlike Nelly's glimpse, Zhang Heng's eyes have captured the movement of that black shadow, although it is only less than a second, but Zhang Heng has already recognized what that thing is.

Yes, that's right, that dark shadow is the half-human, half-mermaid monster he encountered in that mysterious and gloomy seaside town in the previous trial of the shadow set.

Zhang Heng didn't expect that he would actually see these monsters in the real world again.

And unlike the situation when Zhang Heng drove a peerless in the town and defeated a hundred, after entering the water, they actually changed the clumsy way of moving on land before, and became like a fish in water.

After the Black Sail Copy, Zhang Heng's water nature has been exercised very well, at least he can kill most of the people who do not live on the sea, but it is still not comparable to this kind of thing that changes at the genetic level, they are the product of the combination of humans and monsters, breaking the reproductive isolation between species.

It already has the biological characteristics of many sea creatures, and the flippers that Nelly saw before were their real feet, and compared to divers, they don't need oxygen tanks to move underwater, they can breathe directly by their gills, and their speed underwater is at least twice as fast as on land.

On the contrary, Zhang Heng's skills are not as flexible as on land, and every move will feel the resistance from the sea water, and at the same time, he also needs diving equipment to stop underwater, so it is not so easy for him to gain the upper hand here.

If it was just one, Zhang Heng would barely be able to cope with it, but if there were as many of them as in the seaside town before, it would be a big trouble.

This is also the reason why Zhang Heng is so vigilant now.

However, after seeing Zhang Heng's gesture, Nelly mistakenly thought that the other party was just nervous because of this sudden red tide, and just wanted to rise, Nelly could understand Zhang Heng's current mood, this was originally her choice, but that was before seeing "Han Lu", now that she knew that "Han Lu" was by her side, and then let Nelly give up looking for it and take Zhang Heng up directly, it would be difficult for her to pass this hurdle in her heart, especially when the gas in the gas cylinder was still sufficient.

Therefore, while trying to calm Zhang Heng down, Neli wanted to tell the latter that Han Lu was nearby through gestures.

But Zhang Heng still put on a dangerous posture towards her, and Nelly was also a little impatient, I don't know if it was because of the red sea around her, which made her more irritable than usual, especially when she saw the flash of the flashlight coming from a distance, Nelly immediately turned on her flashlight excitedly and shone it on the opposite side, and then she planned to swim over there.

But as soon as she turned around, she was stopped by Zhang Heng, and the suppressed anger in Neli's heart suddenly rushed up.

She didn't know what the relationship between Zhang Heng and Han Lu was, but since the two of them went to Yonaguni Island together for a vacation, it must not be as simple as ordinary friends, but when Han Lu was in danger, Zhang Heng not only didn't want to rescue his companion, but stopped her three times and twice.

Neli put herself in Han Lu's perspective, and now she would definitely feel extremely cold, so she directly broke free of Zhang Heng's arm in a fit of anger and swam towards the place where the flashlight light came from.

At this moment, her heart was completely filled with anger, and she even forgot to let Zhang Heng behind her follow her, in fact, now she has no other thoughts in her head, only the idea of swimming forward, as if she was completely enchanted.

Nelly's diving skills are still very good, and unlike Zhang Heng who is always vigilant around, Nelly is just trying to find Han Lu, so the two quickly separated in this red water.

Zhang Heng was a little helpless, he noticed that Neli was emotionally abnormal, but there was not much he could do underwater, and he couldn't knock Neli out directly. As for Zhang Heng himself, he doesn't know if it's because he doesn't have much of his own feelings left, or because of some other reason, but he seems to be immune to the red sea around him.

And after losing Han Lu and Neli one after another, Zhang Heng became more and more calm.

Because he knew that those half-human, half-mermaid monsters were coming at him, just like in that strange dream and later shadow trial, the other party's target was always him.

But Zhang Heng did not give up looking for the whereabouts of the two girls, because he came to Japan for a vacation, most of his props were not brought with him, and even if he brought it, it would be difficult to come in handy underwater, after all, there was no Lego here for him to assemble, and Paris's arrow could not be shot underwater.

However, Zhang Heng was glad that he still had [Filter Lenses] and [Betty's Shell], these two props were in the thigh pocket of his wetsuit at the moment, sealed with Velcro.

Zhang Heng opened his pocket and first took out the [Filter Lens] from it, which was also the equipment he needed most now.

- The field of view within 300 meters is not affected by factors such as light and natural environment.

This attribute may not seem very brilliant and not very lethal, but anyone who has played a real-time strategy game basically knows the importance of vision, especially in today's environment where you can't see anything clearly.

Zhang Heng took a deep breath, took off the mask, stuffed the [filter lens] into it, and then brought the mask back again, tilted his head slightly, pressed the upper part of the mask with his fingers, and then began to exhale with his nose, and soon the bubbles gathered on the upper part of the mask, squeezing the seawater out from under the mask, and after repeating it twice, the seawater in the mask was drained clean.
