The incense stick that Zhang Wang had lit to tell time had long gone out and he had completely forgotten to refill it. And it was thus he lost track of the day and now that the ash and soot had been cleared from the skies, he didn't really have a good excuse to back it up aside from his own laziness.
Yu Yanlin was no help, snuggling with him in bed late into the morning, not bothering to notify his beloved the elapsing time. The demon king had feigned fatigue, with eyes closed and sleepy groans. He clung to Zhang Wang like a possessive kitten. And who was Zhang Wang to deny him? He revered times like this, where he could run his fingers through Yanlin's hair, and watch his peaceful expression without any interruption.
Zhang Wang was pleasantly lazy, with Yanlin's hand thrown over his belly, he took the time to browse through his system and try to make out what in the world was going on.
