Lin Zhi, a cultural relics modeling specialist, transmigrates to the Great Zhou dynasty and becomes the wife of Shangguan Yu, the male lead she modeled herself. One moment she's helping the emperor look after his grandsons; the next, she's sorting out the family troubles of several princes. In short, after Lin Yimu appears, the tense relations between the royal brothers and their wives, and even between the ruler and his ministers at court, all grow harmonious thanks to her. She also joins Prince Qi, Shangguan Yu, on the border to repel the enemy, ultimately becoming a “worthy princess” who protects the empire and its people.
