Mr. Do's Book on Herbal Medicine

Are you here for some medicine? My medicine will not be made for any random person, so don't just stand there! What? You aren't here for the medicine? A no's a no, but why are you making a face like that? Are you unsure of my skills as a pharmacist?

I am the primary student of Tae Sang. I left Mu Lung a long time ago, seeking my own methods to create medicine, but that doesn't mean I lost my touch! If you do me a favor, I'll make you a medicine right now! What do you think, do you want to help me?

If you really believe in me, then you've got a keen eye for talent! My request is simple. Since I've been away from Mu Lung for so long, I've lost all kinds of formulas that use rare herbs that can only found here. I'd love for you to find Old Paper for me.

What? How am I Tae Sang's student if I don't learn from him these days? Since I had been missing for a while, the teacher seemed quite angered by it and decided not to teach me anything. But if you bring me 25 Old Papers, my skills will match that of Tae Sang!

What? You don't believe me? Go ask Tae Sang right now! Ask him if he remembers a student named Mr. Do?

Eh? Who are you? Ah, you're the one that promised to deliver Old Paper last time. Oh wow? All 25?? You may not look like much, but you definitely seem to be a strong-willed individual. Now, please take this."

The book Book on Herbal Medicine is written by me. The formulas featured in the book cannot be made public, so please don't show it to others. If you bring the book, I'll definitely make you a medicine!

You have not elected 25 Old Papers yet. Well, come to think of it, The Book Ghost at Mu Lung seems to require special codes, which makes it hard to obtain.
