Yu Chizhou, an ancient book restorer at the Provincial Library, took over a dilapidated old book with no author and no date of publication.
The title of the book has only four words: "Principles of Bianhe River Water".
The strangest thing about this book is not that the paper comes from the Northern Song Dynasty, nor that the book records a long-lost river, but that every time Yu Chizhou repairs a page, a line of ink will appear on the edge of the page.
The ink seemed to be written for him.
"Page seven cannot be supplemented."
"There is no countercurrent in the Bianhe River. What is countercurrent is the human heart."
"If you have seen this word, it means there is still someone alive waiting for you in the seventh year of Yuanfeng."
After an unexpected repair accident, Yu Chizhou walked into the book and appeared in the cabin of the Bianhe River in the seventh year of Yuanfeng.
At that time, Bianjing was prosperous on the surface and had good water transportation, but secretly a man-made flood was approaching. Someone tampered with the water register, secretly changed the river map, and privately changed the floodgates, preparing to use the flood to cover up an old case involving several states.
The only thing Yu Chizhou could rely on was his experience in restoring ancient books and the dark river in the book that should not exist.
But he gradually discovered that this book was not waiting for a savior.
It is waiting for someone willing to admit that history is not perfect.
