Liu Wenxuan is reborn from the ashes of a fierce fire and a tainted reputation, returning to the White Deer Academy thirty days before it was ravaged by bloodshed. In his past life, he was involved in a plot by the powerful official Yan Song to silence and eliminate him, all because he had saved a dying man carrying the forbidden book "Records of the Mountains and Rivers." Liu Wenxuan was among those who died with his friends, bearing the shame of treason. In his current life, he is no longer the innocent and passionate young scholar he once was. Holding the memories of the future, he knows that a scroll is about to appear, containing the imperial edict and the evidence of Yan Song's treachery and murder. When the dying messenger falls before him again, Liu Wenxuan calmly retrieves the scroll and, with a clever ruse, plants false evidence in the hands of his rival and friend, Yan Song's pawn, Qin Lie. Liu Wenxuan is no longer alone in his fight, but uses his pen as a sword to split the key passages of the forbidden book, and with the clever tactic of "transmitting books through clothing," he makes every one of the three hundred students in the academy a living "forbidden book," rendering the executioners of the Black Ice Platform powerless. Meanwhile, he befriends his childhood friend, Qin Lie, who is from a noble family but has been hiding due to their family's wrongdoing, and together they form an unbreakable bond. As Liu Wenxuan faces the web of deceit spun by Yan Song, the internal suspicions and betrayals within the academy, and the inevitable cavalry that will arrive in thirty days, he uses his foresight as a chess piece, and the hearts of men as his pawns, to launch a desperate counterattack with words as his weapon and truth as his blade. He must save the academy and bring the history that was attempted to be erased by the flames back to the light within thirty days.
