Prince Murong Jing He of the Great Yan Dynasty led his Weibei Army to reclaim Qingzhou, a lost territory. His triumphant victory should have been a moment of glory, but soon after his army entered the city, a devastating fire broke out. Whispers spread throughout Qingzhou, accusing Murong Jing He of harboring a grudge against the people for their alleged betrayal of Great Yan. Rumor had it that the prince, now known as the ruthless "Butcher General", ordered the city to be burned to the ground. In the flames, a young girl named Mei Lin lost her entire family. Heartbroken and consumed by vengeance, she vowed to kill the one responsible for the massacre. She s a secret organization known as the Shadow Works, where she undergoes years of brutal training after consuming a deadly poison that turns her into an unstoppable assassin. Mei Lin's first mission is finally assigned: to assassinate her greatest enemy, Prince Murong Jing He himself. Disguised as one of a hundred Xiyan beauties sent to the Great Yan as part of a political marriage alliance, she patiently waits for her chance to strike. But what Mei Lin doesn't know is that the man who masterminded her entire assassination mission—setting her on this path of revenge—is none other than Murong Jing He himself.
