Return to Ruins from the Deep Sea: the Call of the Fish Skin Letter

Lu Chen's life was torn apart by a repeated nightmare of falling into the sea. When he woke up from the dream for the seventh time, sea salt appeared out of thin air on his pillow, the fish in the fish tank crashed into him crazily, and the birthmark on his chest became hot with the tide. Grandpa's fish-skin letter and father's logbook before his disappearance all point to a dust-shrouded secret. Behind him are the forces of the deep sea that are pressing closer and closer, and in front of him is the family's century-old fate and the truth about his father's disappearance. There is no way out of this call from the deep sea.
