Yes, I suggested it to the author. Set up some "urban legend" NPCs that need special conditions to find. These NPCs may not be human, they need to take specific conditions to meet, and they need specific methods to invite (such as using temples, altars or rituals) and interact . There are also some superiors and colleagues who work with the players (the players cannot be part-time all day long), such as chefs who bake dim sum together, strong female CEOs, etc., and even make a special "tenant" club system. But the author says there is too much to do and he may update it.
