The Devils Killer (4)
Klaus spent the next four hours sitting on the body of the Flaming Wolf, consuming core after core. He hadn't made much progress leveling up in the past few hours, so he used the time to close the gap. He added the 400 points he gained from leveling up to level 5 straight into his stamina, which helped him recover much faster.
Although his Star Qi was heavily drained, he still had enough to push his Overlord healing passive skill into overdrive. After consuming hundreds of cores from his earlier hunt and eating some regular food, he managed to recover his stamina and restore about 70% of his Star Qi.
He also boosted his experience points to 32 million, leaving him just a million and some spare coins short of reaching level 6. That level-up was crucial—he needed it for his final target, the Dark Flame Demon Wolf, a really nasty creature that would require every skill in his arsenal.
