After Lu Chuan and the others completed their crime scene investigation, Wang Changjiang and Shen Yan began a further examination of the body.
Unlike the focus of the crime scene investigation, forensic doctors primarily determine the time and cause of death through examination of the body.
"Judging by the degree of skin swelling, the body has been submerged in water for more than twenty-four hours."
The degree of skin swelling varies with the length of time the body has been submerged in water.
Wang Changjiang is an expert in this area, having previously dissected many water-logged corpses and is very experienced in judging the degree of skin swelling.
Shen Yan listened attentively, taking careful notes.
Unlike Lu Chuan's rapid progress, Shen Yan's learning has been gradual, having learned a lot from Wang Changjiang over the past two years.
"The degree of submersion is mainly determined by the eyes and fingers."
