There was nothing unusual at the bottom of the sea, and the two men finally prepared to return.

However, at this time, Wen Xian was suddenly attracted by a shadow on the sea not far away.

From the bottom, it looks like a big ship, but the bottom of the ship is different from ordinary ships.

Something seems to be installed underneath.

Just when Wen Xian wanted to take a closer look, suddenly, Lu Xiao pulled her away directly.

Wen Xian was puzzled, but Lu Xiao's attitude was very tough.

Wen Xian also left obediently, because she knew that Lu Xiao should recognize what it was.

And that's exactly what happened.

When the two of them surfaced, Wen Xian released the breathing tube, gasped slightly and asked:

"What's that?"

Wen Xian said, his eyes also looked at the sea in the distance, and a huge boat appeared in this area at some point, but it looked like a ferry for tourists, and from the outside, there was nothing unusual at all.

Lu Xiao also stared at the ship: "It's a submarine detector, to be precise, I'm afraid it's a more complex detector." ”

The ultrasound must have reached a certain intensity that made it impossible for the creatures of this place to live here.

Hearing him say this, Wen Xian suddenly guessed a seven-seven-eighty-eight.

"I don't know who the people are on that ship, and what purpose they are doing this. Wen Xian pursed his lips lightly, his expression complicated.

"Let's get out of here first. ”

The two men then swam to the boat.

Wen Xian wanted to report the situation, after all, it seriously affected the survival of these sea creatures.

It's just that Wen Xian didn't know that at that time, in an enclosed space, two people were standing in front of a screen, and a photo was detected and taken by their device on the screen.

Two black figures in wetsuits appeared in the photo.

"We've been discovered?"

A blonde man said.

Another middle-aged man was wearing a suit and said in a light tone: "Not necessarily, maybe in their opinion, this is just an ordinary ship." ”

"In any case, we still keep an eye on the point, and we can't let these two little divers ruin our plans. The blonde man said.

......

When Wen Xian and the others left the sea again, they encountered another dolphin.

However, this is a dolphin with a fishing net wrapped around its body, and when it approached them, it took the initiative to call for help.

After all, dolphins have a very high IQ, and the IQ of an adult dolphin can reach that of a seven-year-old child.

Wen Xian and Lu Xiao helped it cut the fishing net after entering the water, and it happily surrounded them, and also let out a cheerful cry.

Seeing that the dolphins here were much better than before, the uneasiness in her heart slowed down slightly.

But what Wen Xian didn't expect was that after the dolphins made a quick call, soon more dolphins came over and jumped on the surface of the sea.

Wen Xian watched this scene and smiled at the landing owl, with some indescribable surprises.

"Wen Xian, they seem to like you very much. ”

Lu Xiao looked at these dolphins jumping on the surface of the sea.

The dolphins they rescued swam over and surrounded Wen Xian, their smooth heads touching her abdomen, Wen Xian didn't think much about it, just thought they were grateful.

And Lu Xiao looked at this scene, but his slender eyes deepened slightly.

Dolphins perceive orientation through the sonar that happens, but they also feel life.
