Something that I don't see discussed much is how the Chi You Men are trying to acquire the mirrors so the legendary Chinese monster "Chi You" can be resurrected and devour the world.
I think it's Master Chen who says "if the dragon and Phoenix meet the gates of heaven and earth will open and Chi You will resurrect itself on earth”.
Shenmue 2 opens things up for the supernatural and I'm sure further chapters will expand this even more.
But I want to know what everyone else thinks.. with Shenmue being so grounded in reality are we talking about an actual monster?. Chi You is depicted as a sort of Bull/Ox humanoid, sometimes with multiple arms and as the current series stands it would be very much out of place.
So maybe it's not an entity as such, but maybe a curse or a power that can be harnessed?.
