Broken line is a bleed the whole system kinda thing, but maybe start on the side you broke the line on. You can cheat a little when you put on the new line and cycle some fluid into it before hook-up. Replacement is what it is not really a short cut there.

Dang lol I'm worried about the brake line twisting in half more then anything right now and was hoping there mite be a short cut to doing it all but oh well how long should it take to fix it and do I need to bleed the rear brakes since they are drums. Sorry kinda new to doing brakes when it comes to drums Iv always done 4 wheel disc brakes. This is the first vehicle I have had with both systems.

No. Always start from the wheel furthest away from the master cylinder.

Chances are air has migrated into the proportioning valve and the only wat to be sure it's all out is to bleed everything. Some sort of rust busting spray stuff should help a bit with changing the line. I suggest getting the wrenches for breaking line fittings.
Soak them down and use line wrenches, not ordinary combo's. Sometimes I use a little heat from a MAPP torch if it really won't budge.
Sometimes you end up twisting the line no matter what you do. In that case replace the hard line back to the next fitting. If they're that rusted they probably need it anyway.
BTW check the other wheels too, the flex lines are probably all the same age. No point in doing the no-brake-pucker three more times.

Just remember to always carry a pair of small vice grips. You can pinch the line shut if it ever happens again and make it home or somewhere to fix it, you'll just be minus a wheel to break with.Also if you are low on brake fluid and don't have any use water not anything oil based. Water doesn't damage the system and isn't flammable.

Im decent at flaring lines if I need to. I do it from time to time with 3/8 copper lines for a/c systems in homes and businesses
