A cruise ship was sailing on the endless blue water.
The ship was very big, but once it entered the deep sea, it looked as small as a grain of sand in the desert from a distance.
And the people on it seemed even smaller.
"It is recorded in the old legends that mermaids are inside the sea. They live in the water like fish and when their eyes weep, they can produce pearls."
There were five or six people scattered on the deck, their eyes fell on the young and handsome professor, listening to his explanation quietly.
"Of course, these are just legends." The young professor smiled slightly, "But precisely because of these legends, the ocean seems more mysterious and fascinating. However, since our topic this time is to study marine life, it is beneficial to understand these related legends."
"Professor, do you think these legends are true?"
