that was not 5 minutes
I am guessing all of those guys popping up distracted him before that event so those distractions stopped from paying attention to the ledge which killed him earlier
i was not trying kill everything I was just trying to destroy the remnants of the earth nation because it is much easier to do that than conquer it and keep it under control.
plus I was not killing everything I conquered
I was keeping the fire nation intact
I was only destroying the one thing I that would take a while to co quer
the earth enders
after that I could take down the water nation easily
