There was nothing unusual found at the seabed, and the two were finally preparing to return, but at that moment, Wen Xian was suddenly drawn to a shadow on the surface of the sea not far away.
From below, it looked like a large ship, but the bottom of that ship was unlike regular ships.
It seemed that something was installed underneath.
Just as Wen Xian wanted to take a closer look, suddenly, Lu Xiao grabbed her and they quickly left.
Wen Xian was puzzled, but Lu Xiao’s attitude was very firm.
Wen Xian obediently left because she knew that Lu Xiao must have recognized what it was.
And indeed, that was the case.
When the two surfaced, Wen Xian removed her breathing tube and gasped for air as she asked,
"What was that thing?"
As Wen Xian spoke, her gaze also shifted towards the distant sea surface, where a huge ship had appeared at some point, resembling a ferry for tourists. From the outside, it looked completely normal.
Lu Xiao also stared at the ship, "It’s an underwater detector, to be more precise, probably a more complicated detector."
The ultrasound must have reached a certain intensity, making it impossible for marine life to live in this area.
Hearing this, Wen Xian immediately pieced together a rough idea.
"I wonder who is on that ship and what their purpose is." Wen Xian pursed her lips, her expression complex.
"Let’s leave this area first."
Afterwards, the two swam towards their boat.
Wen Xian intended to report this situation since it severely affected the survival of the marine life.
But what Wen Xian did not know was that at that moment, in a closed space, two people stood in front of a screen displaying a photo captured by their equipment.
And in the photo, two black figures in diving suits appeared.
"Have we been spotted?"
Another middle-aged man, dressed in a suit, spoke indifferently, "Not necessarily, perhaps to them, it’s just an ordinary ship."
"Regardless, keep an eye on them, we can’t let these two divers spoil our plans," the blond man said.
As Wen Xian and her companion were leaving the area, they encountered a dolphin.
However, this was a dolphin tangled in fishing nets, approaching them actively seeking help.
After all, dolphins are highly intelligent; the intelligence of an adult dolphin can match that of a seven-year-old child.
Wen Xian and Lu Xiao dived into the water to help it cut free from the fishing net. It joyfully circled around them and even emitted cheerful calls.
Seeing the dolphin in better condition compared to the previous one eased the uneasiness in her heart slightly.
However, what Wen Xian didn’t expect was that after the dolphin emitted its cheerful call, more dolphins soon came over, leaping above the water.
Wen Xian watched this scene, smiling at Lu Xiao with an indescribable sense of delight.
"Wen Xian, they seem to really like you."
Lu Xiao watched the dolphins leaping at the surface and said.
The rescued dolphin swam over, circling Wen Xian, its smooth head even nudging her abdomen. Wen Xian thought nothing of it, taking it as a sign of gratitude.
Seeing this, Lu Xiao’s slender eyes deepened slightly.
Dolphins use sonar to navigate but can also sense life through it.
