Alright, so most people seem to be on the side of the spirit, and I've been pretty much convinced by those arguments. That said, the spirit literally told us not to get involved. There might be reason for that. Given the inhuman mentality of spirits, it might not thank us for interfering when it already told us to bugger off. Also the entire situation is rather unclear, and I'd rather Ling Qi only jump to fight when she has a clearer reason than 'because my gut says so'.
Therefore, I choose to side with the spirits and Ling Qi's own common sense by picking

Spirit doesn't want us interfering in this fight, let's go wander around, try to get more info, and see if we can jump into some more pivotal fight.
