Why was it impossible for White Night Killer to have a second movie?

" Murderer in White Night " was a mystery novel. It was about Lin Yuhui, a criminal police officer, who had a life and death struggle with his prey, a mysterious character, while tracking down a serial killer. At the end of the story, Lin Yuhui successfully caught the murderer, but he also realized that he had lost the trust of this person and this person was already dead. Because the story ended with the death of a character and did not give a specific cause of death, the author, George Miller, explicitly forbade readers from expecting a second book. In fact, George Miller had no plans to write a second novel, so White Night became an out-of-print novel. It's important to note that this doesn't mean that readers can't find novels similar to White Night Chase elsewhere. It's just that these novels may not be as original as George Miller's or as influential as White Night Chase.
