'Blood sure'?

What's the meaning of'Blood sure'?

[MrPedantic]

Hello DF

It might mean "blood certainly", e.g.

1. Blood sure is red = blood certainly is red.

Or a coinage that means "as sure as blood":

2. The pact between us is blood-sure = the pact between us is sealed in blood.

Or a typo for "bloody sure" ("bloody" is a mild and slightly old-fashioned British intensifier):

3. I'm bloody sure that didn't happen = I am very sure that didn't happen.

Do you have more context?
