Lin Yuan, a modern scholar of Song Dynasty history, accidentally traveled through time and became Wang Shen, the Prince Consort of the Northern Song Dynasty, and was caught in the whirlpool of the Wutai Poetry Case. He relied on his prophecy to try to reverse the tragic fate of his best friend Su Shi, but failed at every step and was frightened at every step. Alienation turns into fetters, and early warning turns out to be ironclad evidence. Every rational intervention becomes a gear that drives fate in the face of the great wheel of history and the inevitability of human nature. When the dust settled, he finally realized: Human beings cannot learn lessons from history, and real tragedies have already been forged while trying to avoid tragedies. This is a bloody dialogue between knowledge and destiny, a sad elegy in which the time traveler becomes a footnote in history.
