Zhou Chengjin had never seen ghosts since he was a child, but he had been frightened and often had fevers. When he was nine years old, his fever persisted and even offering incense and worshiping Buddha did not work. A Taoist priest passing by gave him a knife to bless his growth.
The knife has been wrapped in black cloth. There is an inscription on the inside of the black cloth, sealing the knife.
People attack, and swords receive.
