Southern Dynasty: The Empress's Mentor Returns to Slaughter Them All

(Wei-Jin era setting + political intrigue + woman disguised as a man + the revenge of a ruthless power minister)

“Swallows that once nested beneath the eaves of the Wang and Xie mansions now fly into the homes of ordinary folk.”

She was a daughter of the Xie clan of Chen Commandery, one of the most illustrious families to flourish for two centuries during the Wei, Jin, and Northern and Southern Dynasties. When her country fell, her family was destroyed, and the glory she had held as the emperor's tutor turned to dust along with it.

When she opened her eyes again, she was back before the fall. The foreign invaders had yet to arrive, and the traitors within had yet to be purged. Then she would strike without hesitation and carve out a new golden age.
