Shen Li appears to be the cold and ethereal chief senior disciple of Taiqing Palace with a firm Dao heart, but she is actually a seasoned appearance-obsessed person who cannot hide her thoughts, her heart full of infatuation and complaints about her master Lu Wuchen. Believing her disguise is perfect, she does not know that Lu Wuchen, the number one sword supreme of the three realms who cultivates the ruthless Dao, can actually hear all her inner thoughts. From initial rage and bashfulness to being attracted by her lively and authentic self, Lu Wuchen's Dao heart is completely shaken by her, and after going through entanglements, the two finally become a celestial couple.
