Ling Shuang (a post-apocalyptic S-level ice + healing double superpower), after time travel, her ability was suppressed to F level by the rules of the world. She needs to gradually unlock it and discover that her superpower is the key to purifying the "filthy power" of the beast world.
· World view: The beast world is being eroded by the mysterious "black spot disease". The infected beasts will turn into bloodthirsty beasts, and female fertility will drop sharply.
· Core conflict: Ling Shuang's arrival is not only the hope of saving the world, but also regarded by all forces (including some corrupted ancient beings) as the "key" to break the balance or... The most perfect "container".
