Leonel took deep, heaving breaths. It had been a while since he needed to breathe so heavily to get something done.
His battle with Coldar lasted almost an entire week. Leonel wasn't sure if time in the tribulation and the time outside were the same or not, but regardless, a week here still very much felt like an entire week.
Even when he clearly had the upperhand, the Fiend Demon had refused to give up, forcing them to continue the battle again and again. To make things worse, the Fiend Demon's regenerative abilities were simply off the charts, it didn't seem like Leonel could cause it a single injury that could actually harm it.
