The Ruthless Killer's Revenge

Lee Hyun, the deadliest assassin ever produced by the Valley of Villains, faces his final trial before leaving the order: five lethal beauties sent by his master Gwi-hee, each bent on killing him. But Hyun, having already reached the pinnacle of "absolute heartlessness," subdues them all without a moment's hesitation and earns his master's approval. Reborn as the Valley's strongest killer, Hyun steps into the outside world and crosses paths with Yook Si-eun, a poisoned woman hunted by Black Dragon Clan ninjas. Even as she begs desperately for help, he coldly turns away—until the ninjas' provocation draws a chilling bloodlust from him, his gaze seizing the room like a blade.
