One of the main reasons Raze had attacked the Lethal Bite Clan in the first place was to breakthrough, to become a middle stage warrior.
He had been struggling for a while now and had reached the peak of the initial stage. His power was still growing, but he hadn't broken through to the middle stage.
It wouldn't be an exaggeration to say that he might have been the strongest 6th stage warrior in the whole of Pagna, no, in the history of Pagna.
There were a few ways one could grow stronger and try to break through to the next stage, but there was something that Raze had that made it easier for him compared to others.
That was the deadly extraction technique. So skilled at using the technique, Raze could even use it in the middle of a fight to drain his enemies somewhat.
The more energy one had, the longer it would take to fully drain them. Which was why most of the time, it wasn't something he would use in battle.
