When I opened my eyes again, I went back to three months before I was killed. As an ordinary civil servant in the archives, I was naive and weak in my previous life, and eventually became the outcast in the revenge chess game. This time, I will use the secret files in the archives to uncover Gu Yanchen's revenge conspiracy and find out the serial murder case behind him. But during the investigation, the fear from my previous life repeatedly invaded me, and I began to suffer from brief mental trances. Fortunately, the cold detective Lu Chenyuan broke into my life. Although he questioned my abnormality, he could always protect me at critical moments. In this game of chess, I am no longer a chess piece, but the chess player. I must let all evils surface!
