Now turn back; this path leads back to the first floor of the tower. Lower this staircase (remember this staircase), so you won't need to teleport when returning later.
After entering the main gate, go right.
Come over and insert the switch you just picked up (don't forget to dismantle it for recycling).
You can obtain "Hunyuan Stone" behind the furnace.
After obtaining the Hunyuan Stone, you can teleport directly to the top of the tower and hand it over to the friendly Ghost Messenger. This will also refresh subsequent quests.
