I've turned on the tube puzzles and the wiring puzzles in Dragon Noir, but I can't find the third generator.
I think you need to go as far left as possible and then fly to reach it.
I'd appreciate if you can give me an advice too.
I cannot find a way to reach the generator located at the top of this screen (as I suppose). The problem is that if you take flying ability from puddle near checkpoint, it will expire before you can get to this screen :(
