In her past life, the half-demon maiden Yu Xi was ostracized and used by the immortal sects, only receiving long-overdue kindness from Zhong Xian of the demon clan at the end of her life. Reborn, she gains the ability to hear inner voices, decisively rejecting her hypocritical fellow disciples and following the outwardly cold yet inwardly warm Zhong Xian into the demon realm. Assuming all demon cultivators feared by everyone were cold and ruthless, she never expected her master and senior brothers to be harsh in words but soft in heart, protecting her like a precious treasure. As past conspiracies float to the surface, Yu Xi grows amidst familial companionship, joining hands with her new family to uncover the truth and rewrite her destiny.
