Characters in horror movies often meet their doom while "going to the toilet." The same holds for paranormal novels. By extension, this logic should also apply to Mysterious Dungeons.
Yet, Mingliang stood tall, unabashedly announcing, "I need to go to the toilet." If anyone present had read too many fantasy novels, they would have gasped and muttered, "Truly terrifying."
This instance offered a highly realistic experience. Going without meals led to hunger and drained stamina; lack of sleep caused drowsiness; and not using the toilet resulted in the distinct sensation of an overfull bladder.
Apparently, Mingliang's bladder had reached its limit. His face was flushed, as if he'd just been kissed by a beautiful woman. But Gu Mian knew Mingliang hadn't experienced such good fortune; his bladder merely felt like it was about to burst.
