Ye Qing observed for a while, determined the location, and then left. According to Handsome Fatty Wang, these people wouldn't be able to break through the cave until tomorrow night at the earliest, so he certainly wasn't going to wait here day and night.
By the time he rushed back to the city, it was already past four in the morning. Ye Qing didn't stay at a hotel; instead, he went to the place where Monkey and the others were staying and rested there for a bit.
In the morning, Monkey and his brothers returned from outside. Ye Qing had initially sent them to find Handsome Fatty Wang, but they obviously couldn't find him. As the twelve-hour effect of the pill was nearly up, they couldn't just linger outside.
Monkey was actually the most anxious one, having personally experienced the effects of the "poison." So, after Ye Qing woke up, Monkey stayed close by, carefully serving Ye Qing and the other as they had breakfast.
