Pan Long put the old steward's corpse into the Replica Classic of Mountains and Seas. He wasn't worried it would contaminate anything—as long as he didn't spend spiritual energy to redeem it, nothing from the Classic of Mountains and Seas World could leave the book. It would simply dissolve into spiritual energy in the world between.
That went for the corpse of a mere mortal who worshipped an Evil God. Even the Evil God itself would be no different.
He was curious, though. If this world really was as the deranged Old Count had claimed, and the planet beneath their feet was actually a sealed Evil God, what would happen if that Evil God followed him into the world between?
The spiritual energy released when it collapsed would be a sight to behold...
Of course, it was only a thought. He didn't believe a word that madman had said.
The game had no explicit plot, but it offered hints from several directions. The clearest evidence was that the Moon God's account of this world was completely at odds with the Old Count's. The Moon God said the world was merely a deity's dream, while the Old Count said it had been built upon a deity's body. They agreed that "once the deity woke from its dream, this world would collapse," but on almost everything else, their stories differed.
As for nonsense like "if such-and-such happens, the world will be destroyed," pick any lunatic who believed in some crackpot religion and at least nine out of ten would say the same thing. The ones who didn't were the rare exceptions.
Anyone who believed that stuff really ought to see a doctor and get a thorough brain scan, just to check whether the folds in their brain were smoother than everyone else's...
