Jing Shen Nian

On a spring night in 1992, in the rain at Nanjing Medical College, top student Lin Hong disappeared mysteriously after studying in the evening. Three days later, her body was dumped in a manhole on campus, and her clothes were scattered in another well. Blood stains and vague shoe prints in the hallway became the only clues. B-type blood stains, the fleeing shadow glimpsed by the school guard, the missing iron rod... The murderer was like a ghost blending into the rainy night, making the case a knot in the mind of Interpol Li Jianguo for twenty-eight years. Time goes by, the campus is renovated, and the evidence is covered with dust, but the oath at the well remains unchanged. In 2020, incomplete DNA fragments collided in the gene pool and sparked sparks, pointing to a seemingly ordinary man in Pei County, Xuzhou. When the lights in the interrogation room came on, behind Ma Mougang's smile were the dragging tracks buried by the years, the fragments of clothes when climbing over the wall, and the long-overdue phrase "You are finally here." Beneath the deep well, the echoes of sin never cease.
