Lin Zhi transmigrates into the Yongle era as the daughter of a minor official. She assumes her life will amount to little more than household chores, marriage, and children, with a chance to watch the Yongle Encyclopedia take shape along the way.
That is, until she discovers a scrap of paper hidden in a secret compartment in her father's study, bearing the ominous words “Mars guards the Heart.” To protect her family, she is forced into the fog, carefully navigating the gaps between ancient texts and the imperial court.
She thinks it is merely a plot targeting her father.
Then, one snowy night, she takes shelter from the rain at a tea stall on a street corner. A gaunt old Daoist sitting across from her suddenly pushes a worn, yellowed silk booklet her way.
She looks down. On its cover is the name of a forbidden book lost to history: The Tui Bei Tu.
The old Daoist's voice is as soft as falling snow, yet every word is startling:
“Someone is using it to rewrite history. I, however, want to use it… to change the fate of the Great Ming.”
“And you are the only one in the divination who can wield the brush.”
From then on, she hides at the edges of women's quarters, the history archives, and nautical charts, using ink as her needle to quietly stitch together the broken threads of the dynasty's fortune.
She restores records of natural disasters that were erased; she adds safe harbors for fleets sailing overseas; she plants the seeds of elementary texts that women a century in the future will be able to read.
Years later, the histories record the Yongle Golden Age as one of favorable weather, peaceful seas, and flourishing education.
No one knows that at a tea stall on a snowy night, someone handed over a forbidden book, and someone else accepted a silent brush.
The game of the empire's fate had already begun, with a move made where the ink was not yet dry.
