Whether or not Mo Cheng's story was true, the information he had told her was something Li Meirong could no longer choose to ignore. He claimed they had both been transferred into a novel he had read as a child, and whether or not that was indeed what had happened, his knowledge was too important to overlook.
If he was indeed correct, then that would mean Zhu Qingyue was the greatest villain of this world, and would somehow end up being imprisoned after being beaten by Mo Cheng. And that was only if Mo Cheng even managed to defeat him in the first place.
If he wasn't able to defeat Zhu Qingyue, then wouldn't that mean that this world would be, ultimately, destroyed?
As Li Meirong thought on this, the image brought about by the pixie's illusion flashed through her mind once more: Zhu Qingyue's monstrous form, looming over her as he ate her alive.
