Ten years ago, his parents disappeared mysteriously, and ten-year-old Lin Ye was selected by a mysterious organization to become a candidate for the guardian of the night. Ten years later, he returned with superpowers and memory fragments, only to find that the city was undercurrent, strange beasts were rampant, and forces from all sides were entrenched. Every night, he transformed into a shadow hunter, tracking the monsters hiding in the darkness - until he discovered that the guardian's fate was far more cruel than imagined. When the truth gradually emerged, the missing organization appeared again, and the parents' clues actually pointed to the top secret place. This time, he chose not to protect it, but to destroy the entire night.
