The mysterious sea under the modern background is an uninhabited desert island that seems to be lacking in resources but actually hides mysteries. There are no zombie mutations, and it focuses on natural survival and a two-person world.
Core conflict: The heroine Su Mian's "brain-boosting emperor/drama queen" attribute VS the cruel (and unfair) reality of survival on a deserted island.
Survive by going against the grain. Others' survival is "Survival in the Wilderness", and the heroine's survival is "Longing for Life", living on a desert island. The laughter is created through the contrast between the heroine's crazy inner complaints and her calm appearance (or pretending to be dead).
