Princess Ning's Night at the Pavilion

Princess Ning Wanxiao, the legitimate daughter of the Grand Marshal, was sent to the palace as a maid after her father was assassinated by Emperor Murong Xu. Determined to kill the emperor and avenge her family, she escaped the Emperor's humiliation and accidentally fell into the pavilion of Wei Changting, the supervisor of the Western Factory. Wei Changting is actually the former Crown Prince Li Changting, who disguised himself as a eunuch for ten years to control the Western Factory while seeking revenge and restoring the country. He also holds a deep affection for Ning Wanxiao from her childhood kindness. The two form an alliance to face the coming crises together.
