Gui'an Dao

In the chaotic times of the late Yuan Dynasty, Gui Fu, a young man from a military household in Gui'an County, Huzhou, was involved in a shocking mystery due to his ancestral "Gui'an Sword". This ancient sword is engraved with the inscription "Twenty-three years of the Yuan Dynasty". The "water ripples" on the sheath hide a miniature hydrographic map of the Tiaoxi River Basin. The "curled grass pattern" on the sheath and the ancestral motto "it will appear when it is green" point to a cross-era secret command system that integrates optical, chemical and physical triggers. Local military and political official Liao Daheng regarded it as a "key" and incorporated Gui Fu as a "decoder". Through curriculum training and personality shaping experiments, he forced him to decipher the truth about Gui's old ministry and the control of Taihu-Tiaoxi water transportation in the "curse of knowledge". This is a hard-core decryption of intellectual battles: an interdisciplinary puzzle of hydrology, ekiden, dialects, ordnance, chemistry and optics, intertwined with the love of father and son, the doubts of master and apprentice, and the righteousness of the old department; it is also a tragic song about "guarding the return to peace" - the truth is scorching, sobriety is the price, and true peace is sometimes hidden in the edge of a sharp edge that cannot be sheathed.
