In the ninety-sixth year since the founding of Dayong, historians not only recorded the past, but also determined who had existed.
The father of Gu Shenyan, a junior official at the National History Museum, was convicted of "forging the former prince". In thirty days, his name will be cut off and he will completely disappear from the memories of relatives and friends and the reincarnation of the world.
In order to save his father, Gu Shenyan saw the erased old ink on a page of abandoned history. He can make up for the true history with witnesses, physical evidence and civil evidence, but he must pay the price with his own memory.
When he wrote back the name of the former prince, someone in the imperial mausoleum that had been sealed for hundreds of years opened his eyes, and the fate of the country was shaken. Gu Shenyan finally understood: some lies maintain peace, and some truths are enough to make the world fall back into old disasters.
Since the immortal relies on the history of history to live forever, he uses the truth as his blade to kill the immortal from the history books.
