I Raise My Grandma in a World of Rules

My name is Chen Sui. I was born in the millennium and am a left-behind child raised by my grandmother. On the day I graduated from graduate school, the whole world was suddenly covered in countless "rules." Those who broke the rules died miserably, with their bodies covered in red rashes and mold spots. The survivors fled in all directions, but I went against the flow of people and returned to my hometown. Pushing open the wooden door of the old house, I saw my grandma sitting in front of the stove, waiting for me to eat as she did before. But I remember it clearly - she died three years ago. A broadcast came from outside the house: Residents are advised to note that if the deceased returns, do not look at them and do not eat anything. My favorite pickled fresh food is stewed on the stove, and the heat is filled with the aroma of rotten bones. Grandma turned back and picked up the bowl with a smile: "Nanny, eat it while it's hot."
