Sorry. The answer may be obvious to some but I want to be sure. In a way this is a generic question but likely the tickets would be CX hence putting it here.

I know if you buy a ticket from A to C and if it needs to stopover in B, and if there is a delay in the leg A->B, the airline will get you to C eventually.

However, what happen if I deliberately break it up. Like, I buy (in one ticket) A to B, self-made a stopover of 10-14 hours, then B to C. What happen if there is a delay on the leg of A to B beyond 10-14 hours, would the airline still get me to C free of charge? Here is a solid example: Normally a flight from LHR to ICN would stopover HKG for a few hours but I want to break it up so that it is LHR->HKG, 10-14 hours later HKG->ICN. What if there is a delay on the first leg beyond 10-14 hours, would the airline still ship me to ICN on the next available flight?

Grateful for some clarification here please.
