Unlocking the Quest 
•Prerequisites: You would need to have completed earlier quests in Chapter I, likely including "An Impromptu Change of Plan" or similar introductory quests in Liyue that familiarize you with the region.
Quest Walkthrough
1.Starting the Quest: This quest might begin by speaking with an NPC at a significant location in Liyue, like Liyue Harbor or near Mt. Tianheng. This could be Ganyu, Keqing, or another character involved with Liyue's administration or the Adeptus.
2.Visit the Adeptus: You're directed to seek out an Adeptus or another mystical figure in Liyue, which often involves going to a high or secluded place like Jueyun Karst or Mt. Aozang.
3.Ascend to the Clouds: Travel to Skyfrost Nail or a Similar Location: You might need to climb or use mechanisms like wind currents or geovishaps to reach an elevated area, often involving puzzles or combat with elemental creatures or hilichurls.
4.Meeting the Adeptus: Upon reaching the designated spot, you'll meet an Adeptus like Cloud Retainer or another guardian of Liyue. This meeting might involve a discussion or a task to prove your worth or intentions.
Complete the Adeptus's Task
5.Trial or Challenge: The Adeptus might set a task for you. This could be:
6.A Combat Trial: Defeat waves of enemies or a mini-boss in an arena-like setting.
7.Puzzle Solving: Use elemental skills to solve environmental puzzles or activate ancient mechanisms.
8.Errands: Sometimes, it might involve fetching items or ingrefornts from dangerous or hard-to-reach places.

•Character EXP Materials: To help with character leveling.

Quest Tips 
Team Composition:
•Geo Characters: Since you're dealing with Geo puzzles and interactions, having Geo characters like Zhongli, Ningguang, or the Geo Traveler can be beneficial for creating constructs or resonating with Geo structures.
•Healer: Always ensure you have a healer like Barbara, Jean, or Qiqi to keep your team alive, especially if you encounter combat situations.
Exploration and Navigation:
•Use characters with abilities that help with mobility. Venti's ability to create an upward wind current can help in reaching high places, or use Anemo Traveler's skills for similar effects.
•Look for wind currents or Anemo rings to glide higher or further, which might be crucial for reaching certain areas or solving puzzles.
Puzzle Solving:
•Geo Constructs: Interact with or place Geo constructs on pressure plates or use them to reach higher platforms. Remember, constructs can also block mechanisms or protect you from environmental hazards.
•Elemental Sight: Use Elemental Sight to reveal hidden mechanisms or clues that are not visible to the naked eye.
Combat Tips:
•Elemental Reactions: Use these to your advantage, especially in areas where enemies might be clustered. Swirl (Anemo + another element), Crystallize (Geo reactions), or other reactions can give you an upper hand in battles.
•Protective Characters: If you have characters that can create shields (like Noelle or Zhongli), use them to minimize damage, especially during puzzle sections where combat might be unexpected or environmental damage could occur.
Environmental Interaction:
•Clouds or Mist: If the quest involves clouds or mist, look for interactions that might clear paths or reveal platforms. This could involve activating certain mechanisms or using specific elements like Anemo to disperse clouds.
Quest Mechanics:
•Follow the Narrative: Pay close attention to dialogues and cutscenes. Characters might give hints about what to do next or how to interact with the environment.
•Use of Items: There might be specific items you need to cook or collect. Ensure you follow the quest instructions to prepare or find these items.
Preparation:
•Food and Healing: Before starting, cook plenty of food for healing and buffs. Also, have dishes that can revive characters just in case.
•Leveling: Make sure your characters are adequately leveled for the recommended quest level to handle any combat with ease.
•Save Often: Use waypoints to save your progress, especially before attempting puzzles or entering what looks like a combat scenario.
•Co-op Mode: If you find the puzzle or combat too challenging, consider entering co-op mode. Other players can sometimes offer different solutions or help with tougher enemies.
Keep in mind that details might evolve with game updates or if there are variations in how quests are structured in different versions of the game. Always check in-game for the most current quest steps or consult recent players' guides for any changes or updates to this quest.
