Bleach Manga thread (SPOILERS)

1) If what happened in there didn't carry over outside of the reality, it would be pointless doing any sort of training in there.

Actually, no. Training could carry over without any injuries either of them gets carrying over as well. Training taking place there makes perfect sense if injuries don't carry into the outside world. You have a battlefield you can blow up as much as you want without getting any attention, you can train for however long as you want without any problems, you can train until your body is broken and bleeding but once you're in the outside you're completely fine.
