"But their numbers... There are too many Dream Builders, right? Is it because they can't be completely killed?"
"Sneering Angels cannot be completely killed, they are a manifestation of supernatural powers permeating through the layers"—he recalled the exact words once spoken by Old Mo, it turns out this was what the Night Watchman told Old Mo.
"Their number is not that many." The Night Watchman denied, "Most often it is the same one, or the same group, their souls only infiltrate the layers and possess the people in the mundane world; they themselves cannot return."
