During the Yonghe period of the Eastern Jin Dynasty, the powerful minister Huan Wen made three northern expeditions, and undercurrents surged between the government and the public. When Lu Wenyuan, a clerk from a poor family, was handling a secret report in the military mansion, he discovered that there were two versions of the military report. On a rainy night, a mysterious businessman forced him to deliver a strange bamboo slip, but the person who contacted him died under the Suzaku Bridge after delivering it. Lu Wenyuan was involved in a fatal chess game between three parties: Huan Wen's confidant Xu Miao threatened his sister's property and ordered him to spy on his political enemy Xie An; the Xie family gave jade as a sign of goodwill, and his daughter Shi Qingyi repeatedly tested him; an even more mysterious organization with the name "Crane the Moon Shines on the Water" left behind ironclad evidence of corruption in the military and a packet of powdered medicine called "Three Days of Drunkenness".
