Li Ange, an ancient painting restorer in society, has an unknown secret: he can touch ancient paintings, sneak into the creation scene with his consciousness, and feel all the emotions in the pen and ink. This ability is a curse, forcing him to endure the joys and sorrows of thousands of years, until the criminal investigation captain Jiang Shubai came to his door with an unsolved case.
The police detected the human tissue of the victim who was murdered three years ago in the paint of the national treasure "Thousand Miles of Rivers and Mountains". When science fails in the face of mystery, Jiang Shubai, who firmly believes in logic and physical evidence, has to turn to Li Ange's unexplainable power of "empathy".
One is the detective in the painting, able to see the truth buried by time; the other is the anchor in reality, defending order in the fog. When the two were forced to partner up, they discovered that there was a mysterious organization hidden behind the case that could use or even create "evil paintings". And Li Ange's past is inextricably linked to all of this...
The truth is hidden in the depths of ink. They must break into a painting that spans thousands of years, and pursue a cruel conspiracy that wanders between ancient and modern times amidst the storm of emotions and the murderous intent of reality.
