The human world is on the verge of collapse. The depths of the blue sea are both full of infinite hope and hidden in bloody darkness. The peaceful life of the Geocentric Mermaids has been broken. Faced with the invasion of human technology, what should they do? Desire and nature, aliens and humans, where is the hope of life in the vast world?
In the unpredictable political situation and the indistinguishability of friends and foes, human scientists and underwater mermaids work together to overcome the crisis of trust, mediate with different forces, and establish a profound friendship.
