Youyou is innately endowed with the power of spiritual communication with all beasts. Before the Xuande Gate, with just a few milky, cute words, she tamed the rampaging fierce Xuanming black panther from the Western Regions. The nine-phoenix silver lock, a relic of the late empress worn around her neck, arouses the suspicion of the tyrant Xiao Chong, who temporarily imprisons her in the side hall of the Chonghua Palace. With her purity and kindness, Youyou successively melts the hearts of the cold-faced crown prince Xiao Jingyuan, the proud second prince Xiao Jingyan, and the gentle third prince Xiao Jingyu, forming an alliance of three princes to protect their sister.
