Nodding my head in response I walked slowly towards his desk. He unstoppered the potion and handed out the knife. Hesitating, I grabbed the knife and poke a different finger. Hovering my finger over the opening, I let a drop of blood drop into the potion. The potion slowly turned into the same shimmering red as my potion did. He took the potion and swirled it a couple of times. Then he slowly poured the potion onto the parchment.
