Emphasizing a negation with "bing"
One of the many uses of 并 (bìng) is to add emphasis to a sentence that uses 不 or 没. Because you're emphasizing a negation, 并 is often used when expressing disagreement, or pointing out a flaw in someone's argument. While the word 并 is not inherently combative, it can certainly be used that way.
You can take pretty much any sentence with a negated verb,and give it a little extra kick with 并. Just put it before the 不 or 没. Note that when used with 不, you can negate an adjective as well.
Subj. + 并 + 不 + Verb / Adj.
Subj. + 并 + 没（有) + Verb
