The trigger location of the [Time and Wind] world quest is on the unnamed island to the right of the original Mondstadt Star Cliff. The general route is from the teleportation point in Mondstadt's Fallen Star Valley to the Star Cliff, then a long flight to the island, and finally through the wind field and wind ring to the Temple of Thousand Winds. The general flow chart is as follows
Starting from the teleportation point of Falling Star Valley, go all the way up to the top of Star Reaching Cliff. You can see the nameless island to the right.
After your physical strength is restored, you can set off. If you are almost out of physical strength during the journey, quickly open your backpack and eat Northland smoked chicken (preferably delicious), and then fly a short distance to the island.
After arriving on the island, go directly to the right and you will see a tent and a pile of rocks that can be broken.
After breaking the pile of rocks, you can see a note underneath. After picking it up, open the backpack to view the contents.
According to the content on the note, adjust the time to 2 a.m., turn on the elemental vision and look at the sundial and surroundings
You can find 4 strange green light balls on the island (under elemental vision),
Pick up wind seeds and fly upward)
Note that the last green light ball is on the water. It needs the rock attribute character's Wild Star as a stepping stone to break it, or the ice attribute character creates a piece of ice on the water surface.)
