Netherworld Doctor's Orders

My body temperature is 28°C and my heartbeat is 12 beats per minute. With my left eye I could see the "stuff" filling the hospital. My right hand is often clenched unconsciously - as if holding an invisible chain. Colleagues whispered: Dr. Shen hasn't been feeling well lately, and he always smells like a morgue. They were right. I literally just came back from the morgue. After Fengdu collapsed, the world became a hunting ground for evil spirits. And I, a doctor who died once, became... The last night watchman in this hunting ground.
