One of the aboriginal humans was injured by glass shards from the aquarium that suddenly exploded, causing chaos in the area. While peeking through the slit of his clamshell, Hei Anjing noticed that the room they were in was something close to a laboratory. This can mean he is currently a mermaid considered an experimental subject.
One human had his face stabbed by glass shards and was squirming on the ground while covered. By the time the other humans had arrived, they saw the scene inside the laboratory, and the one they checked first was the aquarium instead of the injured human.
A man in a white robe said, "Get another aquarium! The little mermaids will die with less water at such a young age! Who the hell destroyed the nest of these little mermaids?!"
AGHHH~
