Qi Ming'er's Weird Adventure

"This is an adventure novel with a different world intertwined with supernatural beings and technology + a single-line narrative" . As long as Qi Ming'er can remember, the thirty-meter-high giant wall and the giant trees surrounding it have stood on the edge of the city. It seems like they have grown up together on this land. When she was young, she always liked to pester her grandfather and ask: "Who lives outside the wall?" And grandpa's answer is always the same: "There are ghosts and ghosts living outside. Your parents were killed by those ghosts."
