This remote fishing village has a rule passed down from generation to generation: every blood moon year, everyone must close their doors and windows tightly on the night of sacrifice, and no one is allowed to go out no matter what sound they hear. As the town's night watchman, Lin Mo shouldn't have interfered with taboos, but he saw that thing with his own eyes on the watchtower - a huge tentacle floating from the sea, and every inch of his skin was covered with rotating eyeballs.
He wanted to run, but found that the entire town was surrounded by invisible walls.
