Through dozens of different cases, this book entangles multiple characters such as lawyer Qin Zheng, prosecutor Zhong Jiani, forensic doctor Lin Zhou and his assistant Lu Yuwei, and villain lawyer Su Wenyuan. Social hot spots, extreme disputes, ethical controversies, workplace games, family feuds and life choices unfold in turn. Some cases are funny and absurd on the surface, but in fact they hide profound human struggles and legal dilemmas. The three volumes respectively focus on young lawyers' first entry into the workplace, persistence and decision-making in complex cases, and finally the in-depth dialogue between the system and human nature. The book is full of legal humor, satire, and warmth, showing the light and gray of the law. In the end, the characters gradually understand the practical significance and boundaries of the law through their own growth and struggle. The whole book has a tight rhythm, a coherent story, and distinct character growth. Multiple story lines are parallel and intertwined, and are laid out delicately but without losing interest.
