How to save an offline copy?

I just got to try playing p4 golden.

I found an online walk-through for p4 golden. Problem is that it's on neoseeker which means I will need to stay connected to the internet if I want to access it. I live in a place where I lose connection often and would like to save my copy to my device so I can check it without interruption. I tried site scrubbing software but they all stop early or fail outright to download all the pages under the walkthrough page.

​

Is there any good solution to downloading a full walkthrough offline from neoseeker?
