The recommended novel for solving cases in broad daylight was " Cracking the Case: The Beginning of the Fusion of Police Dog Olfactory Genes." This novel told the story of an ordinary police officer, Luo Fei, who solved one bizarre case after another by fusing with the police dog's olfactory gene through a gene fusion system. He had gradually climbed from a small policeman to the top. The novel was about a detective, and the plot was compact and fascinating.
