The dead of night did not mean much to cultivators. Some techniques needed the light of the stars and moons to advance or even just the lack of the sun itself. Sleep was more of a choice for Immortals so stopping at sunset was no longer a requirement either.
Still, cultivators are social creatures and taking time to rest from a day or more of labor was normal. Isolation was also normal for cultivation sessions.
Thus night time could be lively or empty depending on the location.
Lind and Delenn chose to leave at the deepest part of the night. The moons in the sky were currently far away on the horizon so it was even darker than normal. The pair were currently at an alley in Amber Scale City.
Unlike before when they got out of Kun City, they were not using a gateway at all.
"You know they will be angry at us." Delenn teased him but he only nodded. She understood they had to be gone before anyone noticed they were not in their alcoves in the cavern.
