When he was six years old, Qi Yuan witnessed the tragic death of his parents and brother at home. The blood soaked her father's unfinished chess game, and also soaked her entire life thereafter. She was the last child hidden by her mother's body, and the only survivor of the massacre. Her adoptive parents, the Gu family, gave her a second life, and her sister, Gu Nianan, spent twelve years of companionship, gradually warming her frozen heart.
Twelve years later, 18-year-old Qi Yuan stood on the podium of the World Go Championship and became the youngest world champion in history. There were flashing lights in the audience, but she spoke calmly: "My name is Qi Yuan. Twelve years ago, my parents and brother died in the 719 massacre. I hope the public security organs will restart the investigation."
One stone stirs up a thousand waves. The murderer of the year appeared again - encrypted emails and voice-changed phone calls pushed Qi Yuan into a new abyss. They asked her to hand over the chemical experiment records left by her parents, which were the secrets of the core technology for making new drugs. Otherwise, her current relatives will repeat the same mistakes they made twelve years ago.
When her asthmatic sister Gu Nianan was kidnapped in a video, and when the nightmare from twelve years ago reappeared, Qi Yuan joined the task force as a police psychological consultant. She fought side by side with the criminal police captain Jiang Huai and the police academy student Jiang Hongzhou, using the precise layout of Go to solve unsolved cases, and using the blade of criminal psychology to uncover the deepest darkness of human nature. She gradually discovered that the person who killed her whole family was not just one person, but a huge and intricate criminal network.
There are nineteen ways on the chessboard, and every step is life or death. In this round, Qi Yuan not only wants to win back the truth, but also protects her remaining family.
Intent: Use rational chess games to open up the abyss of human nature, and use love and protection to transcend hatred.
