More than half of the Lesser Demons in the underground arena were defeated quickly with the combined efforts of Liam, Ludwig, and the other Natives.
Everyone contributed in their own way when it came to obliterating the Lesser Demons, and nobody overdid it, well almost nobody. While Kian, Felicia, and Olivia were doing their utmost to make sure that they could defeat as many opponents as possible without endangering their own life, Ludwig was the exact opposite. He didn't worry about the Shedim around him and viciously cut everyone in his way apart.
His fighting style, if one could call it such, purely consisted of destruction. There was no poise, or elegance in his movement. But that was not something Ludwig required to mercilessly butcher hundreds of Shedim in less than half an hour. Most of the opponents Ludwig defeated were Ordinary Shedim and Elite Shedim but that didn't really matter much when it came to demonstrating his dominance over the Lesser Demons.
