Lin Mu studied the ruler carefully and figured out its level. 'Peak Immortal Grade Weapon.'
His expression became slightly more serious. He had expected the Bone Ruler to be powerful, yet seeing the weapon's complete form still exceeded his expectations.
What Lin Mu did not know was that the Bone Ruler was a special existence for the old man. It was not always such a strong weapon and originally had been a mere mundane bone. The elders who had suffered under his punishments knew the story quite well.
When the Head was just a new elder, he used to be quite cordial, but disciples used to take advantage of that and abuse his kindness. Eventually he had enough and was so furious that he picked up an oily bone from a tray nearby and started beating the disciple who had angered him.
