Remove Next & Previous Post. Not Just Hide.

I just want to remove next and previous post link from my posts. I know CSS code can hide the links but the links will be still visible in source code and visible to google bots. Moreover hiding a link is not really good staff at all as google warns against hiding links. So my question is how can I completely remove next and previous post links from my website.

** Even though I am using colormag theme and I asked them several questions in their themegrill forum but most of the time they are not answering. This is may be their business policy. Whatever is it if anyone can help me to understand where wordpress usually put codes (I assume php functions) for showing next and previous post links I think I can figure out myself what codes are liable for previous and next links in colormag theme.

Any help will be highly appreciated.
