Here's how you can approach the "Overstretched" World Quest in Genshin Impact based on general patterns and common game mechanics.
Unlocking the Quest 
1.Prerequisites: Typically, you would need to have completed certain parts of the main story (Archon Quests) or reached a specific Adventure Rank. Given the information from sources, you might need to complete the "Ending Note," which is part of the Prologue: Act 3 Archon Quest.
2.Location: Look for the quest start near Bishui Plain in Liyue. Specifically, you might find the quest initiator, Qiaoxi, standing on the north end of a bridge south of the Statue of The Seven in Dihua Marsh.

3.Starting the Quest: Speak with Qiaoxi. Make sure to select the dialogue option that accepts the quest.
4.Investigate Nearby Camp: Head to the area Qiaoxi directs you to, which could involve swimming or gliding to a nearby island or camp.
5.Combat: Engage with the enemies at the camp. For enemies like a shielded opponent, use elemental reactions; for instance, use Pyro to break a Geo shield.
6.Return to Qiaoxi: After clearing out the enemies, return to Qiaoxi to report back. This might involve another conversation to conclude the quest.
Quest Rewards
•Adventure EXP: Approximately 300
•Primogems: Around 20
•Mora: 20,000
Quest Tips 
•Elemental Advantage: Ensure your party has a good mix of elements to deal with different enemy types effectively. Pyro for wooden shields, Electro or Cryo can also be useful depending on enemy types.
•Swimming Tip: If you need to swim to an island, remember the swimming technique mentioned: hold the sprint button (R1 on PlayStation-like controls) and tap forward on the joystick intermittently for efficient swimming without quickly depleting stamina.
•Quest Dialogue: Always choose the option to help or investigate further when offered in dialogues to ensure you don't miss out on starting the quest.
Remember, while this guide provides a structured approach based on typical quest patterns in Genshin Impact, specifics like exact locations or enemy types might vary slightly with game updates or if there are variations in quest implementation. If you're having trouble finding or initiating the quest, checking in-game quest logs or speaking to NPCs in the mentioned areas should set you on the right path.
