Weird Resurgence: the Knocker Is at My Door at the Beginning

A time travel begins with an endless hell. Zhang Yu saw a cold corpse that looked exactly like him in front of him, and there was a strange knock on the door outside the door at night. Then the blood moon rises into the sky and all ghosts travel. Streets, buildings, crowds... There are ghosts threatening death hidden everywhere in the world. All sentient beings can only hide in a small space and tremble, lingering and waiting for death. The world needs a savior. It was not until later that Zhang Yu understood that only he could save the world.
