After the "Great Melt", the "miasma sea" that corroded all things swallowed up the old world, and humans huddled in the last isolated island city. Ling, a young man who made a living by scavenging, accidentally discovered an ancient compass that was not corroded by the miasma sea during a deep-sea operation. This compass does not point to the north, but stubbornly points to the legendary "Eternal Night Lighthouse" that has long been abandoned. In order to find out the truth behind his parents' disappearance and to unlock the secret of the compass, Ling embarked on a route to the forbidden land. There, he met the mysterious tower guardian and gradually uncovered a shocking secret about the survival of mankind and the sea of stars. This is not only a journey of survival, but also a redemption of civilization.
