Plants on Fu Erdie's balcony that mutated after the apocalypse. They can dissolve corpses completely, distinguish between different types of blood, absorb blood and convert it into white light that heals wounds and purifies the apartment. Their branches and roots can seal cracks, absorb insects and odors as waste, purify air by drawing in smoke, and self-repair the apartment. They also protected Fu Erdie during her four-day unconscious state by sealing the room tight.
