Here's a comprehensive guide on "The Tree who Stands Alone" quest in Genshin Impact, based on general gameplay patterns and information available up to my last update.
Unlocking the Quest 
1.Location: This quest typically begins in Mingyun Village, located in the Liyue region.
2.Quest Giver: You need to speak with an NPC, likely a ghost named Yuan Hong, found near a bulletin board or a notable spot in or around the village.
Quest Walkthrough
3.Starting the Quest: Talk to Yuan Hong. He'll give you some background story and direct you toward finding his lost will or notes.
4.Finding the Lost Notes: Head to a nearby hut or area in Mingyun Village where you'll find the "Book of Lost Notes" or similar item, which will give you clues or directly mark the locations of the will fragments on your map.
5.Collecting the Will Fragments: First Fragment: Usually located in a small cave or nook near the starting area, possibly requiring you to glide down from a higher point.
6.Second Fragment: Might be inside another cave within the village, hidden behind some breakable objects or ores.
7.Third Fragment: Often requires you to travel a bit further, possibly to a cliff or a secluded spot where you might encounter enemies like hilichurls or slimes.
8.Fourth Fragment: Could be inside a mine or cave, with some mining involved or near a mining cart.
9.Confrontation and Completion: After collecting all the pieces, you might encounter some Treasure Hoarders or need to solve a simple puzzle involving the environment (like digging at a specific spot or activating something with a shovel).
10.Return to the tree or the area indicated by the quest to finalize the quest, possibly involving some digging or interaction with the environment to unearth a treasure.
Quest Rewards
•Adventure EXP: Around 400
•Primogems: Typically 50
•Liyue Shrine of Depths Key: One key to unlock a shrine for more rewards.
Quest Tips 
•Combat: Be prepared for minor combat in some locations where the will fragments are found. Enemies might include hilichurls, treasure hoarders, or geo slimes.
•Exploration Tools: Use characters with abilities that help in exploration, like Anemo Traveler's ability to create an upward gust or any character with a claymore to break ore quickly.
•Map Navigation: If available, use the game's navigation or pin system to mark locations on your map if the quest doesn't auto-mark them for you.
•Co-op Mode: If you're finding it challenging to locate the fragments or deal with enemies, consider entering Co-op mode where other players can help.
Remember, while this guide is based on patterns common to Genshin Impact quests, specifics might vary with updates or new content released after my last knowledge update in early 2024. If the quest mechanics or rewards have changed, looking up recent guides or posts on gaming forums or X would provide the latest insights.
