When you get down to the Torii gate in Aruami, if you go to the left, there is a cube puzzle that is unrelated to the Cleansing Defilement quest.
You will not be able to access the Teleport Waypoint nor the Domain if you do not do these quests. Once you’ve completed the world quests “ A Strange Story in Konda” and “ Sacrificial Offering,” you’ll be tasked with finding three more shrines in the quest “ Cleansing Defilement.” One of these shrines is in Aruami. Our Genshin Impact guide will provide the cube puzzle solutions.
There are several sets of puzzles in these ruins that you’ll have to complete in order to unlock access to a Waypoint Teleporter and a Domain. Once you complete several of the quests in the Sacred Sakura Cleansing Ritual world quest line in Genshin Impact, you’ll have access to the Araumi ruins.
