Arthur slammed the Knight's body to the ground, and it caved under the weight of Arthur's spiritual arm. For some reason, the barrier that made him unable to attack others couldn't deflect his spiritual power.
"I've made myself clear." Arthur walked toward the bars, and they bent open to allow him through. He stood beside the Knight of Nobility. "I don't care about your status or your titles. If you insult those with me, prepare to die."
"Don't get arrogant." The Knight of Nobility struck the ground to get up, creating a hole in it. He levitated in the air as he grabbed his grabbing the hilt of his sword.
Blinding light exploded from the Knight's arm as the heat rose. Arthur frowned as he felt space compress, and he side-stepped.
The sword slash flew past his face and destroyed his cell, room, and tore a large part from the wall. Arthur disappeared from his spot and appeared behind the Knight. He struck with an open palm covered in liquid fire.
