An inexplicable drop was usually a plot in novels to show the helplessness and despair of the characters in the face of setbacks. It could be a conspiracy or an overt plot, depending on the background of the story and the character of the character. In some cases, the decline could be due to external interference or internal corruption. This decline could be a conspiracy. For example, in Dream of the Red Chamber, Jia Baoyu described his situation after he was robbed in Yi Hong Courtyard as "down and out, as if he had sunk into a bottomless abyss, as if he had fallen into a fog, and his future was bleak." This decline could be due to the conspiracy of external forces. In other cases, the decline might be due to the character's own reasons. This decline might be an overt plot. For example, in Water Margins, Lin Chong lost his official position and status after being recruited by Liangshan Lake. However, he was not intimidated by the decline and chose to accept reality and continue to work for Liangshan Lake. This decline could be due to the character's own efforts and decisions. Whether it was a conspiracy or an overt plot, an inexplicable fall could become an important element in the plot of a novel to shape the character and the plot of the story.
