I found this sentence in a book:
I think I kind of understand it: something like "Ignoring the narrow dug paths, I chose the direction in which many abandoned lights hung, and proceeded while devising my own way", but I'm not sure about what いかにもついでに and ような means in this context.
I think those two parts, いかにもついでに and ような, are not linked in a single form. As for いかにもついでに, I know the single words いかにも and ついでに, but I'm not really sure about what they mean in this case.
For context, the character is trying to find her way to the surface, and after finding a service tunnel and opening it by thawing some ice, there is not sign she dug any passage; there is not much added by the text, as far as I understand, since one chapter ended with the character entering the tunnel, and the next started with:
followed by the sentence I'm unsure about.
All in all, my guess is:
- the paths in questions aren't dug by the character, but they are already there
- いかにも is linked to 無視, meaning she is completely ignoring those paths; or maybe is linked to ついでに掘った, reinforcing it
- ついでに is linked to 掘った, and adds a sense like those paths were dug incidentally, while digging the main path
- ような means "ignoring the path that looked like they were dug incidentally", so is how the character perceives them, rather than an objective fact
but I'm not really sure.
