"My shadow, my light - this is the oath engraved in the bones of every Night's Watchman."
Yu Cheng, an ordinary college student, was attacked by a heart-eating demon on a rainy night. In order to protect his loved ones, he awakened the forbidden ability to control shadows. When he discovered that his mother had been a member of the mysterious organization "Night Watch" and that he had a cursed bloodline called the "Shadow King" flowing in his body, his fate had already been rewritten.
"Rookie, remember -" Leng Yan captain Bai Yue threw the blood-stained Tang knife to him, "the more shadows devour, the faster the humanity will be lost."
But when the fourth-level shadow beast tore the city apart, and when his relatives and comrades fell in front of his eyes, Yu Cheng still chose to let the darkness swallow him completely. The moment the shadow wings that covered the sky spread out, he saw the truth clearly: the so-called curse was just the cruelest gift from the gods to mortals.
In a world where shadow beasts feed on fear, the most dangerous monsters often wear human skin. And true light is born from the deepest darkness.
