When Zhang Heng opened his eyes again, he regained his vision, and it was clearer than before the red tide appeared. This was the first time he used his Filter Lens underwater. Initially, he was worried that the red tide did not fall under the natural category, but now, it seemed that the lens worked well in this red tide.

The red tide disappeared before him, and the seawater became transparent to him within 300 meters.

Zhang Heng soon found Nellie, who had separated from him earlier. The latter now swam toward the ruins. And in front of her, Zhang Heng's old friend, a half-man, half-fish-frog monster, was holding a flashlight, flashing at Nellie to draw her closer to him.

Zhang Heng did not spot other monsters beside him for the time being.
