For several miles around the castle, the canyon was clear of all locusts. With the curve of the black river forming a natural barrier on three sides of the castle, Z really only needed to focus on defending the front of the castle once he cleared the sides.
As it turned out, clearing the locusts wasn't as hard as he had imagined. He literally had only begun the intro to his custom background music, and they all died. Yet Z would never believe that the trial in front of him was so simple.
His devilish boss would never miss out an opportunity to make him work, and since Lex wanted him to get some real world experience, there was no way that the scourge of locusts would be so easily dealt with. The very fact that Z could not determine what trouble it was that Lex expected him to face itself revealed that he was lacking in experience.
He analysed the situation in a little more depth. He recalled the mercenaries they had brought the Inn to, and their condition.
