Until this point, both sides had only been sending out 3rd class soldiers and the occasional 4th class to manage them. Even Niflheim's mass-produced Puppet Mechs couldn't surpass the barrier of 4th class strength.
This was the result of choosing quantity over quality.
When Long Chen and his private militia entered the fray, things became even more chaotic. Asgard and Niflheim weren't able to just focus on each other anymore, they had to be wary of countless others who wanted to reap benefits from their conflict.
But Long Chen's group was different from those vultures. Their advent onto the battlefield earned them the nickname of "Bloody Cavalry," depicting how they charged in without fear and caused a river of blood to flow under their feet.
