Without hesitation, Lex used Evisceration on the robot that had spoken. But as he had long suspected, the technique had no effect. No matter, he didn't mind doing things up close and personal.
On his fists, he was currently wearing iron knuckles that he had bought from the Guild room. Unlike normal iron knuckles, these could be charged up using Lex's spirit energy. Once they were charged, the next time they made contact with anything, they would release a concentrated burst of energy. That, accompanied by Lex's ridiculous physical strength, made it so no spiritual technique was required. Brute strength was enough to take down any foe he faced, so far at least.
That was exactly why Lex threw himself at the robot that had spoken earlier and kicked its body. He did not want to defeat it too quickly. He did not know if the robots felt pain, but he definitely knew the satisfaction of beating it senselessly.
