The day Shen An returned to his hometown from the provincial capital, his father's urn was still collecting ashes on the storage shelf of the funeral parlor. No one in town told him that his father fell from the second floor of the morgue. He took over his father's shift and worked the night shift, a thousand and one nights. On the first night, the body in cabinet No. 3 In the morgue sat up on its own. The next night, he touched the hand of the body and saw an image - the night his father fell, there were three people in the morgue. On the third night, Deputy Director Jiang came to the funeral parlor to have tea with him. He smiled and said, "Xiao Shen, your dad's matter has been settled. Don't pry around." Shen An said, I didn't ask. After Deputy Director Jiang left, Shen An took out his mobile phone. On the screen was a photo of skin tissue scraped from the fingernails of the right hand of the body in Cabinet No. 3. He sent a message: Check this DNA for me. Recipient: Provincial Forensic Center, Director Zhao.
