Yi Hang is a courier with special abilities. He sent an A-item, but the recipient was swallowed by a black vortex in front of him. All that was left at the scene was a button-sized launcher and a "beat six" gesture. He was suspected by the police and fired from the company, but received a suicide note from the deceased—— "Find that library and destroy all dark supernatural books." Dongxu Association gave him a direction: special correspondent. But he didn't know that his life experience had the same origin as those sealed dark powers. He didn't even know that his father's disappearance was also related to this incident. There was only a garbled message that no one could decipher, still lying in the bracelet. Some answers have been hidden for a lifetime, and it's time for someone to find them. This novel and its characters are purely fictitious.
