The Colorless Devil Deep in the Sea Fog

After the century-old disaster known as the "Great Flood," the planet inhabited by humans was almost completely submerged by sea water, and the survivors could only live on the last artificial island, Noah Island. But when humans began to rebuild their homes, toxic sea fog began to drift to every corner of the planet all year round. At the same time, "mechanical sea beasts" from the depths of the sea appeared, as well as mutated human groups-"devil species." Different demon species have different powers. They lurk in human society. Although their numbers are very small, their destructive power is extremely strong. Therefore, the demon species are expelled, eliminated, or conducted various experiments by ordinary humans on the island... In the 89th year of the New Calendar, there were more and more radical demon species.
