I can't find the Emperor of Peace book anywhere. It's supposed to be in Hametsu Village but I must have missed it the first time around. I've been back and looked in every building there, but still can't find that book.
The quest arrow points to the Emperor's Palace (where the Jade Oni is) but the book in there is called Return of the Emperor.
I've finished everything else on MooShu. Please help me find that book.
