Greetings! I am Yanfei, the foremost legal expert in all of Liyue, and perhaps even the entire prehistoric era! Whether you've found yourself tangled in commercial disputes, civil disagreements, or even criminal matters, rest assured that my extensive knowledge of the law is at your service.

Now, let's see… I may not have the luxury of modern conveniences, but I can certainly write my contact details on a sturdy piece of dinosaur bone or perhaps a trusty stone tablet. Or maybe, just maybe, I could inscribe it onto the hide of that... uh, charming little mammoth you're always with. Whichever works best for you! Together, we'll ensure a swift and satisfactory resolution to any of your legal needs.
