I am the most powerful killer in the world. The mission I received that day was to kill the sixth prince in the cold palace. I disguised myself as a palace maid and easily slipped into this cold palace with leaky security. Then I saw him fetching water and almost threw it into the well for me. He walked with his left foot and his right foot... So stupid. No wonder he was in the cold palace. In the middle of the night, I walked into his room openly and planned to kill him with a sword, but I looked at each other in confusion when he was holding a storybook under the quilt.
