My Prison Cellmate from Time Travel

Xie Yun looked down at himself - his tattered coarse clothes were stained with blood, and his wrists were bruised by the rough iron chains. He pinched his thigh hard, and the pain made him wake up completely. This is not a dream. Three hours ago, he was the deputy director of surgery at a tertiary hospital and had just completed an eight-hour heart surgery. I just took a short nap in the duty room, and when I opened my eyes again, I arrived at this ghost place. System? Goldfinger? Ning Changan called tentatively in his mind, but the only response he received was painful moans from deep in the cell. This novel and its characters are purely fictitious.
