Xie Shuyi sticks to ancient books and official history, and only written historical materials are true; Xiao Yao travels to the mountains, rivers and countryside, believing in folk rumors and historical facts.
Three years ago, the two had conflicting ideas about an unsolved case that had been pending for a century, so they became tit-for-tat and broke up.
Secret relics are unexpectedly unearthed in a silent ancient temple, old cases are stirred up again, and former rivals are forced to work together again.
Distinguish official history and make up for it with unofficial history. One person writes a book tracing the origin, while the other person travels on the wind to explore the world. They dismantled the mystery of time in the secret realm of mountains and rivers, dispelled their obsessions and cleared up their past suspicions through side-by-side investigations. Two-way reconciliation, strong forces working together to overturn a century of injustice and restore the tampered historical truth.
