❤️ Main Relationship
步重华 (Bu Chonghua) × 吴雩 (Wu Yu)
Fandom ship name: 葱花鱼 (Cōng Huā Yú, from Chonghua's "scallion" and Wu Yu's "fish")
✨ Introduction
Tun Hai is the second book of Huai Shang's Po Yun (Breaking Through the Clouds) series, shifting the focus from the first book's Yan Xie and Jiang Ting to a new pair in the same narcotics world. Bu Chonghua is a model police captain — academy-trained, disciplined, health-conscious, and cold to the point of arrogance. Wu Yu is a low-ranking officer who seems unmotivated and allergic to authority, hiding a past nobody in the precinct is meant to know: he spent twelve years as an undercover agent inside a drug cartel, going by the name A Gui (阿归), and lost the only person who knew his real name when his brother-in-arms Xie Xing (解行) died in the cartel's Red Mountain interrogation room to protect his cover.
The romance grows out of the cases: Bu Chonghua is assigned to lead a new anti-narcotics effort, Wu Yu is quietly pulled back into the field, and the two men — one who was saved by a child named A Gui twenty years ago and one who never expected to be saved at all — keep colliding until suspicion turns into trust and trust into devotion. It is a 强强 (equals) pairing: both are exceptionally good at their jobs, both are stubborn, and neither surrenders easily.
🌏 Background
The story is set in the fictional coastal city of Jinhai, in the same shared universe as Breaking Through the Clouds. It opens with the "502 skull" case and expands into a wide investigation of transnational drug trafficking, money laundering, and the cartel network Wu Yu once lived inside. The central mystery runs on two tracks at once: what the cartel is planning in Jinhai, and what exactly happened during Wu Yu's twelve years undercover — a history told in fragments of memory, scar tissue, and the snacks he stress-eats (spicy strips above all). Readers of the first book will see Jiang Ting and Yan Xie again in supporting roles, but Tun Hai stands on its own case file.
🎭 Themes & Tone
- Trauma and survival: what twelve years undercover costs, and what it cannot take
- Mutual salvation: two men who each believe they are beyond saving
- Police brotherhood and found family, including the women of the precinct
- Moral ambiguity: loyalty, revenge, and the line between justice and vengeance
- Romance between equals, earned slowly inside a case-driven plot
Tone: gritty and intense, with sudden flashes of deadpan humor (mostly snacks) and a hard-won HE.
👥 Main Characters
- 步重华 (Bu Chonghua) — young captain of the anti-narcotics unit; academy elite, severe, secretly romantic, obsessed with healthy eating
- 吴雩 (Wu Yu) — transfer officer hiding a legendary undercover past; reads people instantly, flinches from care, loves spicy strips and instant noodles
- 解行 (Xie Xing) — Wu Yu's brother-in-arms from the undercover years; his death in the Red Mountain interrogation room is the wound the whole story circles
- 江停 (Jiang Ting) & 严峫 (Yan Xie) — the leads of Breaking Through the Clouds, appearing as senior allies and reluctant babysitters
✨ Iconic Quote
- 吴雩 (Wu Yu): "Your name is carved beneath the earth; my soul walks toward death — and lives again." (你的名字永刻地底,我的灵魂向死而生。)

🔥 Why It’s Popular
- Wu Yu is a fandom-defining 美强惨 (beautiful, strong, tragic) character — a hero who is damaged, difficult, and utterly human
- The case plot is denser and more realistic than the average danmei police novel, with a genuinely suspenseful long game
- The romance is restrained and adult: two competent men choosing each other, step by step
- Strong reception for its female supporting characters and their friendship, a rarity in the genre
- A satisfying sequel for Breaking Through the Clouds readers, but fully readable standalone
