Ling Feng, a celebrated entrepreneur and leading figure in the business world, is found dead in his study on a quiet morning. His suicide note says he took his own life because of work pressure, but the young detective Shen Qing notices a string of anomalies: Ling Feng’s phone contains an unsent text with a string of mysterious numbers hidden inside; the people close to the deceased seem to be keeping dark secrets; and a chain in the study appears to conceal a story that cannot be told.
As the investigation deepens, Shen Qing discovers that what Ling Feng was involved in before his death was not merely ordinary business rivalry, but a vast conspiracy behind an international deal. Everyone has complicated motives and aims, and behind the apparent “suicide” lies a deadly struggle for power.
Amid the fog surrounding the case, Shen Qing gradually uncovers the truth about Ling Feng’s death and slowly realizes that he has become deeply entangled in a vast crisis. As layer after layer of the mystery is unraveled, Shen Qing must not only face threats from the forces behind it, but also make difficult choices amid complicated emotional entanglements.
