Lin Yuan, a modern scholar of Song history, unexpectedly transmigrates as Wang Shen, a Northern Song prince consort, and becomes caught up in the Crow Terrace Poetry Case. Armed with knowledge of the future, he tries to change the tragic fate of his dear friend Su Shi, but every step is fraught with danger. Distance only brings them closer, and warnings become ironclad evidence. Each rational intervention is swallowed up by the wheels of history and the inevitability of human nature, becoming yet another cog driving destiny forward. When the dust settles, he finally understands: humanity cannot learn from history. The true tragedy was forged long ago, in the very attempt to avert it. This is a bloody dialogue between knowledge and fate, a mournful elegy for a transmigrator reduced to a footnote in history.
