Plot Summary of Heavenly Secrets Bureau
Heavenly Secrets Bureau follows Gu Yu Qing, the son of a former Imperial astronomer who was executed under mysterious circumstances.

Determined to uncover the truth, he joins forces with Li Ling Yue, the Ninth Princess of the royal family. But she’s not your typical noble — she’s a skilled healer with a sharp mind, a quiet courage that matches Yu Qing’s determination. Together, they begin investigating a string of eerie and seemingly unconnected events: people struck by lightning, signs of sorcery, strange omens in the stars.
As they connect the dots, they find themselves uncovering layers of hidden truths that all seem to point back to the same chilling prophecy — and to a plot that could bring down the empire itself.
