I worked as a tour guide in the Forbidden City. I was struck by lightning and was struck by an ancient locust tree before I was knocked unconscious. I caught the Soul-Calming Nail in the tree core with my bare hands. When I woke up, there was a black and blue mark on my palm, and ghost figures floating all over the ward screamed at me. Someone from the National Security Bureau pushed open the door and came in: "Ms. Zhong Wan, what you caught is the soul-eating nail from the Qintian Prison of the Ming Dynasty." "There are 30,000 Yin soldiers suppressing the underground of the Forbidden City. The seal was loosened last night."
Behind them, the ghostly figure of a faceless officer slowly emerged.
"I found you," it said with its black hole-like mouth, "the new nail keeper."
