The Mysterious Resurrection of the Doomsday World

My name is Li Cheng, and during an ordinary evening self-study, a mysterious resurgent spirit came to the world. The difference is that the supernatural recovery comes very quickly. In just three months, 90% of the world's cities have fallen. Terrifying ghosts have taken control of the cities, and people have become ghost slaves of the walking dead. And I picked up a strange notebook during the supernatural incident that happened in school. It will help me survive in this world and seek the possibility of ending the supernatural era.
