In these suspense novels, many different methods of murder appeared. For example, in the murder case in " Night of Rose Rain," the murderer's throat was slit, but no traces of the murderer were left behind. In " Record of Leaving the Cliff," Chen Yu used ghost-faced moths, corpse beetles, and other netherworld creatures to kill the tomb robbers who invaded the tomb. In " Nine Mysterious Case Teams," there were cases of killing through space, killing with astrology, and killing by human spontaneous combustion. In short, the killing methods in these novels were varied and ingenious, leaving the readers hanging on their noses and unable to solve the mystery for a long time. I hope you like my recommendation.
