So after saving all of them they decided that he is spy wow kingdom really does have some smart people in it.. he kept reminding them to prepare for battle helped them and now this lol
this is a reference to 10,000 years cultivating in ice cold palace (I think that is the novels name). {edit: 80 Years Of Signing-In At The Cold Palace, I Am Unrivalled was the name.}
