On his eighteenth birthday, Lin An's world shattered.
He thought it was just another ordinary sunset in an ordinary life, but in that dark alley, in order to protect the most important person, the sleeping shadow in his body suddenly awakened and turned into a terrifying force that tears apart reality.
This power brought no glory, only cold eyes and an "invitation" that could not be refused. An organization called "Guardians" told him: Welcome to the real world - a jungle of high martial arts under the appearance of a bright city, with undercurrents of supernatural powers and predators of the weak and the strong.
Here, trust is a luxury and betrayal is the norm. Close friends may suddenly turn against each other, and the harsh instructor seems to be hiding a double face. The lies about his father's ordinary past were ruthlessly torn apart, and replaced by a cruel truth closely connected with the taboo experiment "Shadow Prison".
He is the chess piece, the experiment, and the only key.
Lin An must learn to walk on the edge of lies and conspiracy. Manipulate shadows, devour light, and struggle to survive in a quagmire filled with dangers. He must become strong enough to tear through the darkness that shrouds everything, find the answer to his father's disappearance, and keep the last remaining light in his heart amidst the ashes that burn everything.
This is an urban martial arts sadomasochism legend about growth, betrayal and protection. When the world is full of shadows, can you still believe in the direction of light?
