Reborn seven days before the apocalypse, Yang Shu's first move isn't to stock up on food and water. She rushes to her best friend's home to save her. But all she manages to bring back is a cold corpse and a little child who has cried himself hoarse. She buries her best friend in the backyard, thinking at least she can lay her to rest. After the apocalypse, the safe zone is built, the wire fences are up, and the sheep are back in their pens. Everything is going according to plan. Until one morning, the mound of earth in the backyard splits open. Her best friend emerges from the ground wrapped in a cocoon of silk like a spider's web, while a faint light glows in the little one's palm. The man who helped dig the grave back then leans against the doorframe, smiling carelessly. “Sister Yang, looks like the best friend you planted has bloomed.”
