The quicksand bottle is a reward for the copy of Sun Moon Well. For the first time every day, copies of Riyuejing will be distributed according to the number of "elite" combat rounds. Star sand can be exchanged for quicksand bottles. This treasure chest has three floors. If players want to change, they must choose the best.
You can also get star sand by completing the weekly quicksand bottle task. You can collect more star sand in exchange for quicksand bottles through this task and the copy task of Sun Moon Well. In addition to the Golden Pavilion Fairy, you can also provide advanced animal decisions, treasure dishes, quick secret orders and other rewards (the task is refreshed randomly once a week, and a large number of stars and sands are given at one time).
