Su Linyue, an ancient book restorer, woke up and became Su Heng, the "only son" of the Su family in Lin'an of the Yong Dynasty. His father died young, leaving behind a frail mother and three sisters each with their own unique talents, who also hid a shocking secret of women disguising themselves as men. The shadow of the imperial examination case ten years ago shrouded the Su family, and the powerful Wei Shoufu was eyeing her. However, her true identity was closely related to the Zhenbei Hou Mansion, which held heavy troops.
With an engraved jade hairpin as a guide and half a tiger charm as evidence, Su Linyue was forced to embark on the road to the imperial examination. The smell of gunpowder at the water transport terminal has not yet dissipated, and the writings of Gongyuan have been stained with blood. She not only wants to stand out in the examination room, but also protects her family from the pursuit of the shadow guards, and also needs to uncover the court game behind the child-exchange conspiracy. When the bronze mask slips and the Feng Shui eye is revealed, the puzzle that started in the Guiyou Examination Hall will finally reach its sharpest end between the strategies written by her and the silver scissors in her sleeves.
