I can't say for sure if a particular novel is the most shocking in history because it's a subjective question. Different people have different views on different types of novels. However, some novels may be controversial because of their absurd, eccentric, or illogical plots or shocking dialogue. For example, novels such as The Three-Body Problem, Ghost Blows Out the Light, and Grave Robber's Chronicles were all popular among readers, but some people thought their plots were too shocking. In short,"the most shocking novel in history" was a subjective question. Different people had different opinions.
