Mr. Nian injected his mystical Qi into the bone slowly and watched the piece of bone shimmer with even more luster due to the infusion of mystical Qi. It slowly began to show signs of coldness. As there were more mystical Qi being delivered into it, a blanket of frost eventually formed on the surrounding ground. The temperature sank swiftly to freezing point and kept on decreasing.
Mr. Nian then shifted slightly to scrutinize the God's Bone under the sun. He fed some mystical Qi into the bone again to make certain of its state before cutting it a few times with a short sword. Lastly, he made a fire and attempted to burn the God's Bone.
After several attempts, he could finally conclude that this was the authentic God's Bone. It was genuine without a shred of doubt.
