Duke poured more magic power into the yellow sand, which bound the assassin tightly enough to make breathing difficult.
"If you refuse to say anything, then I'll have no choice but to crack open your skull and take a look myself." Duke only said it to scare him; in truth, he had no real methods of interrogation.
Unlike those Wizards who specialized in souls, who could directly view memories within another person's soul to obtain information.
Upon hearing Duke's words, a flicker of fear flashed through the male assassin's eyes, followed by ruthless resolve.
In an instant, black blood seeped from the corner of his mouth, carrying a foul stench.
In only a moment, after his heart pounded violently several times, it suddenly shattered, killing him on the spot.
Duke did not even have time to stop it. The assassin must have used some method to commit suicide.
He would rather die than reveal a single piece of information, leaving Duke no chance at all.
Duke was a little dumbfounded. He had only said it casually—who would have thought he would scare the assassin into killing himself?
He knew the assassin was not afraid of him. There was probably some consequence even worse than death that made him choose death over leaking information.
Duke was somewhat puzzled. Just who had set their sights on him, to have such utterly loyal suicide agents working for them?
