The sea breeze in Canglu is always wrapped in the salty moisture that cannot be dissolved, but the dead silence at the seaside pier is more suffocating than the thick fog.
Ling Zhou clutched the deep-sea dead wood left behind by his brother, and pieced together the truth about his brother's disappearance amid the fishermen's cloudy eyes and gray-scaled hands and feet. People at the dock were all saying "the sea is shouting". They were staring at the dark forbidden sea line in a daze, chanting "sink" repeatedly. Even the captain of the fishing team was hiding something. When Ling Zhou discovered that light gray scales appeared on the back of his hands, and the old ancestral talisman tattoo began to heat up, he finally understood that his brother's disappearance was not an accident, and the city-state's ban was not protection. The deep sea shrouded in thick fog contained secrets that could drag everyone into madness.
The scales spread faster and faster, and the whispers of the deep sea echo in his ears day and night. Ling Zhou must break through the forbidden sea line before completely turning into "them", find his brother, and also find the indescribable fear that stares at humans in the darkness. This is not only a journey to find a person, but also a game with the sleeper in the deep sea. Every step closer to the truth is an inch closer to madness.
