You can remain Sectless, and you can join only one Sect at a time. Joining is most useful when its weekly rules match your normal play, its shop has something you want, or its signature Martial Art is worth learning early. A clue normally unlocks the joining quest; walking straight to the final NPC does not replace that step.

Hidden Mountain and its Mohist story are officially upcoming, and the July 13 teaser still uses future-tense wording. Until a live patch note, normal region access, and the Mohist Hill Entry Clue agree, the older 墨山道 blueprint and component routes are cross-version information rather than current instructions.
