He Wen, a graduate student in history, accidentally transmigrates to a strange world built from “historical fact,” where the rise and fall of dynasties is dictated by the Heavenly Dao’s edits. He awakens the heaven-defying artifact “Fragment,” which can rewrite small parts of history. But the artifact is guarded by a strict mentor who values historical law above all else and punishes He Wen’s every tall tale with thunderous force. Naturally talkative, He Wen always manages to derail serious historical events at life-or-death moments with modern memes and specious arguments, setting off a chain of wildly imaginative butterfly effects. From the solemn laws of Qin to the absurd banquets of Tang, he struggles to survive between his mentor’s pursuit and history’s power to correct itself. To get home, he must use his silver tongue to bluff the ancients and the artifact to patch up the holes, all without completely shattering the timeline, embarking on a madcap adventure that brings official history and unofficial accounts together.
