As night falls, the editing room of Jiangtan Evening News is brightly lit.Female reporter Zhang Xiaoqian holds an anonymous letter in her hand, her eyes full of nervousness and curiosity.The letter contained a partial photo and a line of disturbing text: A game called “Nine-Gongge” is about to begin.

According to the letter, starting now, every three days, the newspaper will receive one-ninth of a complete photo.Twenty-four days later, when these nine photos are put together, the truth about the Jiangyang murder case will be revealed to the world.But if - Evening News - were to neglect for any day and fail to publish the photos on time, then there would be an explosion somewhere in the city.

After urgent discussions between the newspaper's editor-in-chief Yan Liang and the task force, they decided to adopt a strategy of limited sales and targeted distribution of newspapers, aiming to draw out the manipulators behind it.Yan Liang knows very well that this is a dangerous game, but it is also the only clue to uncover the truth.
