The System told me to found a sect, help all under heaven, and become a grandmaster of my generation.
That does sound pretty good.
But, System, I don't believe a word you say! You're a busted System with a silver tongue, but what the hell is all this?
Where did the ghosts come from? Weren't monsters forbidden from becoming spirits after the founding of the nation? Where did all these demons come from? The Heavenly Palace, the Underworld, Gensokyo...
Oh, right, what's Gensokyo doing here?! System, get out here and explain! Where did all this stuff come from?!
Weren't we supposed to found a sect and let everyone ascend? How did this turn into a mastermind-behind-the-scenes spiritual qi revival story?!
