In the Xia Kingdom, every person awakens with a resonance—a bond to either an element or a legendary beast. Yet Li Luo shattered this expectation, born with a blank resonance that marks him as an anomaly. Though he carries the prestige of House Loulan, one of the five Great Houses, his parents' mysterious disappearance years ago left him vulnerable. The rival houses circle like predators, plotting to seize his family's power, while simultaneously pursuing the stunning Jiang Qing'e—his betrothed and the capable leader now guiding House Loulan through treacherous times. Li Luo seeks obscurity and wishes to dissolve their engagement, but Jiang Qing'e refuses to release him. Stripped of power and burdened by duty, the "useless young master" must navigate impossible choices: discover if his blank resonance harbors hidden potential, shield his House from ambitious enemies, and uncover whether his supposed weakness might become his greatest strength.
