The White Robed Prime Minister

Mulan, the Royal Luck Star, is tasked by the late emperor to marry a prince and secure the succession. Remembering her past love, she assists the eldest prince, Lu Chenzhou, to ascend the throne. Disguised as a man, she becomes the Prime Minister, stabilizing the nation, and later travels to the northern frontier to lead battles against the enemy, turning her black hair white. However, after Lu Chenzhou takes the throne, he fears her achievements, favors the concubine Qin Jiaojiao, exposes her true gender, and humiliates and harms her and her servants. Heartbroken, Mulan severs her ties, resigns her post, and leaves the capital. Subsequently, Lu Chenzhou employs treacherous advisors, disrupts the government, invites foreign invaders, and causes the people to flee. At the earnest request of Lu Yanxiu, Mulan reorganizes the army, pacifies the chaos, and drives out the enemies. Upon the new emperor's ascension, she reveals her true identity, is bestowed the title of White Robed Prime Minister, and aids the new ruler in creating a prosperous era.
