- Shen Wujiu: On the surface, he is a handsome young man from a famous family, but in fact, he is a road fool + a slouch in reasoning. Every time I analyze the case, I can come up with a 100,000-word bloody plot, and I always say seriously, "There is only one truth - the murderer must be for love!"
- Ling Shuang: A cold and aloof iceberg beauty, good at tracking and disguise, but she has a fatal weakness - she is afraid of dogs. Every time he saw Ah Fu's spiritual dog Wangcai, he would instantly lose his power and hide behind Shen Wu Jiu, trembling.
- Ah Fu: The youngest nine-bag disciple of the Beggar Clan, he has his own "Beggars Clan Information Network" and can find out any gossip within ten minutes, but half of his "intelligence" is always false news from hearsay.
