An isolated island in the vast sea, a high-rise building serves as a prison, and the original sin is an indelible mark engraved on all survivors.
The solitary Lan Yi sits on the first floor with her hard power, cold and aloof, and is completely trusted by everyone under her command; Li Yuyi, whose real name is concealed, takes up the safety of the entire building, suppresses his innate rage, and guards the companions who have accompanied him along the way.
The seven buildings are separated from each other, and each has its own leader. Gluttony, greed, jealousy... All kinds of original sins haunt people's hearts. Natural disasters broke the isolation between islands, and originally hostile buildings were forced to unite. Everyone struggled through layers of dangers, making repeated choices between the nature of original sin and the goodwill of human nature, and together they tore apart the secrets of the caged world and embarked on the uncertain road home.
Purpose: Only by facing one's own shortcomings can salvation be achieved
